Climate and Climate Change

Climate Change

Two days before Halloween, 2011, New England was struck by a freak winter storm. Heavy snow descended onto trees covered with leaves.  Overloaded branches fell on power lines.  Blue flashes of light in the sky indicated exploding transformers.  Electricity was out for days in some areas and for weeks in others. Damage to property and disruption of lives was widespread.

That disastrous restriction on human energy supplies was produced by Nature.  However, current and future energy curtailments are being forced on the populace by Federal policies in the name of dangerous “climate change/global warming”.  Yet, despite the contradictions between what people are being told and what people have seen and can see about the weather and about the climate, they continue to be effectively steered away from the knowledge of such contradictions to focus on the claimed disaster effects of  “climate change/global warming” (AGW, “Anthropogenic Global Warming”). 

People are seldom told HOW MUCH is the increase of temperatures or that there has been no increase in globally averaged temperature for over 18 years.  They are seldom told how miniscule is that increase compared to swings in daily temperatures. They are seldom told about the dangerous effects of government policies on their supply of “base load” energy — the uninterrupted energy that citizens depend on 24/7 — or about the consequences of forced curtailment of industry-wide energy production with its hindrance of production of their and their family’s food, shelter, and clothing. People are, in essence, kept mostly ignorant about the OTHER SIDE of the AGW debate.

Major scientific organizations — once devoted to the consistent pursuit of understanding the natural world — have compromised their integrity and diverted membership dues in support of some administrators’ AGW agenda.   Schools throughout the United States continue to engage in relentless AGW indoctrination of  students, from kindergarten through university.  Governments worldwide have been appropriating vast sums for “scientific” research, attempting to convince the populace that the use of fossil fuels must be severely curtailed to “save the planet.”  Prominent businesses — in league with various politicians who pour ever more citizen earnings into schemes such as ethanol in gasoline, solar panels, and wind turbines — continue to tilt against imaginary threats of AGW.  And even religious leaders and organizations have joined in to proclaim such threats.   As a consequence, AGW propaganda is proving to be an extraordinary vehicle for the exponential expansion of government power over the lives of its citizens. 

Reasoning is hindered by minds frequently in a state of alarm.  The object of this website is an attempt to promote a reasoned approach; to let people know of issues pertaining to the other side of the AGW issue and the ways in which it conflicts with the widespread side of AGW alarm (AGWA, for short).  In that way it is hoped that all members of society can make informed decisions.

The Water Planet Earth And Its Climate


Introduction

Many years ago I happened to read a paper by Willis Eschenbach introducing his Water Thermostat. I have forgotten the essence of his paper, but the name stuck with me for years. Now years later and having retired from my normal marine geological activity at the Geological Survey of Finland in 2002, I have been able to dig deeper into the IPCC storyline of manmade global warming. The fact is that my view of the story does not meet ends with the official IPCC storyline where carbon dioxide, instead of being the source of life, is assumed to be the master culprit behind the slight warming of our planet for example since the end of the Little Ice Age 150 years ago. It is said that the warming is caused by the fast developing industrial revolution, luckily learning to exploit fossil fuels, and thus improving human living standards.

Yes! Carbon dioxide has been coined as an evil gas, a pollutant by the US Environ-mental Protection Agency (EPA), warming the atmosphere to catastrophic levels, inducing floods, droughts, super hurricanes and even the “end of humanity”? The ghastly thing is that the IPCC climate narratives have been successfully targeted to scare people in all parts of our wonderful planet with imminent danger due to increasing levels of emissions of CO2 which, as I mentioned above, is in reality, together with water, simply the “must food” for plants, thus also for all life on Earth.

I should point out that from the first IPCC climate assessment report published in 1990, the scare tactics in all four IPCC follow-up reports up to the fifth AR5 WGI science basis report, the scare propaganda has every time intensified. Probably the 6th report, soon to be published, will be close to doomsday propaganda.

In my talk I will try to paint a picture of our planet and how come it has been able to sustain vivid life forms for over half a billion years and this I will do without those complex climate models assumed to be able to mimic nature. But before that, there was recently this interesting link by Professor Toby Tyrrell: https://inews.co.uk/news/planet-earth-has-remained-habitable-for-billions-of-years-because-of-good-luck-8153366. Tyrell a specialist in Earth system science highlighting results of a recent study, published in the Nature Journal Communications Earth and Environment, suggested that “chance” is a major factor in determining whether planets, such as Earth, can continue to nurture life over billions of years. Tyrrell comments: “A continuously stable and habitable climate on Earth is quite puzzling. Our neighbors, Mars and Venus, do not have habitable temperatures, even though Mars probably once did also have water.” Tyrrell concludes: “Pure chance is the reason that Planet Earth has stayed habitable for billions of years.”

I personally do not think that good luck has anything to do with habitability. The fact remains that the conditions for life to evolve have just been plain suitable, i.e. just a few prerequisites are needed:

So what makes Earth so special? Five major reasons!" ...

Key Climate Graphs

Graphs are a powerful tool for illustrating, explaining and summarizing technical information. They are frequently used in climate science to provide historical information and perspective on various aspects of weather, climate and climate change. They are also used to illustrate potential future changes in aspects of climate based on climate models.

The most important aspects of weather in the context of climate and climate change are related to recurring events such as El Nino and La Nina (ENSO), tropical cyclones, floods, droughts, heat and cold waves, tornadoes and wildfires. The extent of the historical records of these various weather events varies. The records are also affected in recent years by the availability of satellites which can detect smaller tornadoes and tropical cyclones which would have been more difficult to detect previously.

The most important aspects of climate and climate change are related to longer term changes (30+ years), including atmospheric CO2 emissions rates and cumulative concentrations, global temperatures and temperature anomalies, global sea level and rate of sea level rise, and model projections of future changes in these climate measures.

One of the primary requirements of good scientific graphical presentations is that the graph cover the entire period for which data is available so that the historical context is available to the users. It is also important that any changes in the sources or methods of collection of the data be explicitly noted. The most significant of these sources and methods issues are the change from proxies to instrumental data and changes in the instruments used to collect the instrumental data.

The following series of commentaries will present several of the most important graphs illustrating each of these climate and weather issues.

    Carbon Dioxide Emissions and Atmospheric Concentration
    Global Temperature
    Sea Level and Sea Level Rise
    Climate Models
    Weather Events

The graphs have been selected to provide perspective on the climate changes and weather events occurring currently. Each graph will be accompanied by observations on its significance and comments on its important characteristics. Note that none of the various line graphs display uncertainty bands, though there is significant uncertainty regarding the graphed values, especially where the graphs include proxy information. The information presented in the bar graphs is typically based on counted observations and thus less subject to uncertainty, though not completely immune from it.

A Short History of CLIMATE ALARM!

 

"1970s Ice Age scare

Numerous reports in the 1970s reflected concern that the Earth was heading towards a new ice age. These are nowadays often dismissed as mere newspaper gossip, but they were far more than that.

Some scientists forecast a full ice age, for instance NASA’s Dr Rasool, who said that air pollution would cause a drop in temperatures of six degrees. Such predictions were of the more extreme variety, but there was widespread acceptance amongst climate scientists that global temperatures had fallen sharply since the 1940s, and that this trend was likely to continue.

The US government was so concerned about events that it set up a Subcommittee on Climate Change in 1974, in turn leading to
the US Climate Program in the same year and the subsequent formation of the Climate Analysis Center, designed to monitor and predict climate change. This was the predecessor to today’s NCEI, the National Centers for Environmental Information run by the US Department of Commerce.

Needless to say, the cooling trend ended soon after the subcommittee was set up, and warming resumed.

 

If the cold does not get you, the heat will!

In the 1980s, the cooling trend reversed, and it did not take long for forecasts of apocalypse to re-emerge, but this time based on the idea of a hothouse planet. In 1989, Noel Brown, director of the New York office of the UN Environment Program did not hold back, warning us that:

  • entire nations could be wiped off the face of the Earth by rising sea levels if the global warming trend was not reversed by the year 2000;
  • coastal flooding and crop failures would create an exodus of ‘eco-refugees’;
  • sea levels would rise by up to three feet;
  • coastal regions would be inundated – one-sixth of Bangladesh could be flooded, displacing a quarter of its 90 million people, and a fifth of Egypt’s arable land in the Nile Delta would be flooded, cutting off its food supply;
  • it would cost the United States at least $100 billion to protect its east coast alone;
  • shifting climate patterns would bring back the Dust Bowl conditions of the 1930s to Canadian and US wheat lands.
  • the most conservative scientific estimate was that the Earth’s temperature would rise from 1 to 7 degrees over the following 30 years.

Well, the year 2000 came and went, emissions of greenhouse gases carried on climbing, and global temperatures rose by a modest 0.4°C. Needless to say, none of Brown’s cataclysms came about either, as later chapters will reveal.

$2 Trillion Climate Plan

President Biden proposed a $2 trillion climate and energy plan during his campaign. He has now begun implementation of that plan, which would provide the funding over his first term in office. The funding would be primarily in the form of incentives to encourage investments in clean energy facilities and equipment and in energy efficiency improvements.

The discussion of this and similar plans rarely includes any mention of the level of private investment and cost required to achieve the plan goals and objectives, or the deadweight losses resulting from replacement of functional facilities and equipment before the ends of their useful lives.

One specific element of the Biden plan is the installation of 500,000 electric vehicle charging stations. This effort would involve acquisition or repurposing of land or building space for installation of the charging equipment, parking spaces for the recharging vehicles and acquisition of additional utility electric service capacity. Depending on the location of the facility, the electric distribution grid might require reinforcement to provide the incremental electric energy. This element of the program would also require some legislative or regulatory requirement for the purchase of large numbers of electric vehicles, probably with continued federal incentive funding to offset a portion of the incremental cost of the vehicles. However, the bulk of the funding for these activities would be private capital.

Another specific element of the program is the upgrading of 4 million buildings and weatherizing 2 million homes. These are both expensive efforts. The building upgrades would be predominantly to commercial and institutional buildings and would likely require substantial owner investment. The home weatherization effort would likely be targeted at low-income homeowners and would probably require a lower percentage of owner investment. Considering the Administration’s intent to terminate fossil fuel use in the US by 2050, the building upgrades would likely require replacement of natural gas, propane and oil heating systems and water heaters with electric equipment, which again might require acquisition of additional electric utility service capacity and perhaps distribution system upgrades as well.

Arguably the most ambitious element of the plan is accelerating the utility industry transition to renewable sources of generation, which the Administration intends to have completed by 2035. This effort would probably require continuation and expansion of federal incentive programs for wind and solar installations, combined with regulatory or legislative requirements for utilities to provide service to these new generating facilities as well as priority positioning in the supply order. As these new facilities come online, they will begin to render some existing utility generation facilities no longer “used and useful”, causing them to be removed from the utilities’ rate bases and abandoned, even though they are still functional.

The abandonment of functional fossil fuel generating stations would not only be a deadweight loss but would also begin rendering the fossil energy resources owned by the utilities and their suppliers as deadweight losses, since the powerplants they supplied were no longer operating.

President Biden’s nominee for Secretary of Commerce has already been quoted as saying that “we need funds for the climate agenda”, though the nature and magnitude of the specific taxes is yet to be determined.

China / Paris Accords

China is the most populated nation on earth. China also has the second largest economy among the nations of the earth. China is a signatory to the Paris Accords, which recognize it as a developing nation. China is also earth’s largest CO2 emitter, producing more than 28% of earth’s anthropogenic CO2 emissions. These factors make China a major force in the global effort to reduce anthropogenic CO2 emissions under the Paris Accords.

Prior to COP 21, nations were asked to submit Intended Nationally Determined Contributions (INDCs) toward the COP objective of reducing global carbon emissions. China’s INDC is summarized as follows:

  • To achieve the peaking of carbon dioxide emissions around 2030 and making best efforts to peak early;
  • To lower carbon dioxide emissions per unit of GDP by 60% to 65% from the 2005 level;
  • To increase the share of non-fossil fuels in primary energy consumption to around 20%; and
  • To increase the forest stock volume by around 4.5billion cubic meters from the 2005 level.

China is clearly making an effort to peak annual CO2 emissions early, as shown in the graphs below. However, they have been far less successful in increasing the share of non-fossil “fuels” in primary energy consumption.

 

China Primary Energy

 

Carbon Dioxide Emissions

 

China currently plans to build an additional 250 GW of coal generation, a 25% increase over its current coal generating fleet. The increased CO2 emissions from these plants would be expected to increase China’s share of global annual CO2 emissions beyond 30%, even with the expected growth of coal generation in other nations.

China President Xi Jinping has announced that China would be “carbon neutral” by 2060, though the new coal plants currently under construction or planned would be expected to have operating lives of 40-60 years, so plants completed in 2030 would be expected to operate until 2070-2090.

China has also committed more than $20 billion for the construction of coal generating stations in other countries, including Bangladesh, Pakistan, Indonesia, Vietnam, South Africa and Zimbabwe. These power generating facilities would further increase global CO2 emissions.

The United Nations, through UNFCCC, is quick to excuse China’s aggressive increases in annual CO2 emissions on the ground of “Environmental Justice”, essentially accepting the Chinese position that its economic growth is a greater current imperative than reducing CO2 emissions in the interest of averting a “climate crisis”, or a “climate emergency” or an “existential threat”. Apparently only CO2 emissions from developed countries would contribute to a “climate crisis”.

The UNFCCC and the developing nations appear willing, even anxious, to watch the developed countries commit economic suicide while they focus on accelerating their economic development.

We are frequently told of the environmental benefits and economic superiority of renewable energy sources, though the developing nations appear to disregard renewables in favor of coal, oil and natural gas. The developing countries are clearly making major investments in fossil fueled electric generation to support their future economic growth, while the developed countries focus on renewables as the path to their economic decay.

Something seems wrong about this picture.

IMPACTS OF CLIMATE CHANGE - PERCEPTION AND REALITY

 

1. The standard narrative

The standard narrative regarding climate change, as represented by the quotes on the opposite page, from some of the world’s most influential people and institutions, is that climate change is already increasing the frequency and intensity of extreme weather events (EWEs) and wildfires, reducing available water and crop yields, increasing diseases, hunger, poverty and human mortality, and reducing productivity of the biosphere and the habitat available for species. It is claimed that these and other climate change impacts are diminishing human and environmental wellbeing, and will reduce them further unless ‘drastic measures to achieve as quickly as possible zero net greenhouse gas emissions’ are taken.

This paper considers whether data on climate-sensitive indicators are consistent with this narrative. Specifically, it examines empirical trends in extreme events, wildfires, water availability, vector-borne diseases, and some indicators of human and environmental wellbeing, such as economic development, poverty rates, life expectancy, biological productivity, and cropland per capita. Since climate change is a global phenomenon, the paper focuses primarily on indicators at the global scale. But it will also examine trends for the US, to a lesser extent China and India (which together comprise over a third of humanity), and, where readily available, aggregated data from developing or low-income countries. However,one should recognise that the existence of a trend in one country (or section of the globe) is not indicative of a global trend.

Moreover, because climate change should not be confused with fluctuations in the weather, the focus will be on long-term trends. Ideally, the temporal record examined should be long enough to, firstly, capture a change in climate. Climate is often defined in terms of 30-year averages. Thus, it should be long enough to define at least two non-overlapping 30-year periods. Secondly, it should also encompass at least one, if not more, full periods encompassing any significant atmospheric or oceanic cycle(s) that could significantly affect the phenomenon for the region under examination. For example, the Atlantic Multidecadal Oscillation, which, it has been theorised, can affect precipitation and droughts on both sides of the Atlantic and hurricane activity in the North Atlantic Basin, has a 60–80 year period.10 Thus, ideally, the temporal record for determining trends for that region should be long enough to span a few of these periods.

Unless explicitly noted, I will use ‘climate change’ synonymously with ‘greenhouse gas induced climate change’.

Misinformation Commission

The past several years have seen the appearance and proliferation of “fact checkers”, some of which are more like “fake checkers” driven by their founders positions on current issues. This evolved into organizations including Facebook, Twitter and Google blocking subscriber content and then banning individuals and organizations from using their services. However, two Duke University professors have now proposed establishment of a federal, “non-partisan” Misinformation Commission, though there is no assurance that such a Commission would be expert or objective. The suggested federal Commission is reminiscent of the Ministry of Truth in George Orwell’s 1984, which was also responsible for the ongoing revision of history.

Climate change would likely be a priority focus of the Commission, since charges of misinformation and the use of epithets such as “denier” and “anti-science” have been commonly aimed at skeptical scientists and politicians by climate change alarmists in the environmental movement, numerous politicians and bureaucrats and by some members of the consensed climate change community. There is even a website which focuses exclusively on exposing and berating scientists and others skeptical of the climate alarmist narrative.

The following are some examples of climate misinformation to assist the Commission.

1. Any statement that climate science is “settled science”, since there are numerous aspects of climate and climate change which are not well understood, including climate sensitivity and atmospheric feedbacks.

2. Any statement that global near-surface temperature anomalies have changed by an increment of one or more hundredths of a degree centigrade, since: the measurements are not made with that precision; many of the measurements are inaccurate and are “adjusted” to correct them; and, many areas of the globe are sparsely measured or unmeasured.

3. Statements that climate models can accurately project or predict future climate conditions, since the models were not able to accurately predict current conditions when they were “tuned” to previous temperature history and none of the models has been verified.

4. Statements that weather events have become more frequent or more intense as the result of climate change, since changes in weather event frequency and intensity have been neutral or negative.

5. Statements that weather events will become more frequent or more intense in the future as the result of some climate change contribution, since these statements are based on unverified attribution models.

6. Statements that the rate of sea level rise has doubled, or that the rate of sea level rise is increasing, based on satellite sea level measurements, since the differences between the satellite sea level measurements and the tide gauge measurements have not been resolved; and, since the purported change in the rate of increase in less than the measurement uncertainty in the satellite measurements.

7. Statements that wildfires have increased as the result of climate change, since satellite data refutes these statements.

8. Statements that climate change is interfering with crop production, since crop production has increased globally and laboratory experiments confirm that increased carbon dioxide concentrations enhance plant growth and the efficiency of plant water usage.

9. Statements that there is a climate “crisis”, or “emergency” or that climate change represents an “existential threat”. These statements are not supported by the IPCC reports nor by the actions of numerous national governments which are aggressively increasing their carbon dioxide emissions to expand their economies.

The climate change which has occurred and is currently occurring has produced net positive effects across the globe. There is no indication that this will change in the foreseeable future.

“The whole aim of practical politics is to keep the populace alarmed (and hence clamorous to be led to safety) by menacing it with an endless series of hobgoblins, all of them imaginary.”, H. L. Mencken

Satellite Temperatures

 

University of Alabama Huntsville (UAH) has released their analysis of lower atmosphere temperature anomalies through December 2020. The current graph is shown below.

 

UAH Satellite- Based Temperature of the Global Lower Atmosphere (Version 6.0)

 

The temperature anomaly decreased by 0.26°C in December 2020, from 0.53°C in November. Dr. Roy Spencer noted that 2020 was the second warmest year in the 42-year satellite record at 0.49°C, compared to 0.53°C in 2016, which was a super El Nino year. The peak monthly anomaly in 2020 was 0.75°C in February, marking the peak of the 2019/2020 El Nino, comparable to the peak temperature in 1998, which was also a super El Nino year.

Dr. Spencer believes that the rapid drop in the anomaly in December marked the beginning of the impact of the current La Nina, which began in the fall of 2020. NOAA expects the current La Nina to persist through at least early Spring and perhaps through the Spring of 2021. It remains to be seen how strong the current La Nina will become, but Southern California Weather Force has issued a super La Nina warning for 2021, projecting the strongest La Nina in recorded history.

The graph below shows the ENSO index values from 1990 – 2020. Note the super El Nino events in 1997/1998 and 2015/2016. Also note that there has not been a very strong or super La Nina during this period. The current La Nina was approaching strong at the end of 2020.

 

Oceanic Nino Index (ONI) - 1990-present

 

Note that ENSO events are not climate events, because of their short duration, but rather weather events. However, both El Nino and La Nina events can have major impacts on global temperatures, as shown in the UAH graph of lower atmosphere temperatures. Note also that, while temperature anomalies returned to pre-El Nino levels after the 1997/1998 and 2009/2010 El Nino events, they did not do so after the 2015/2016 super El Nino. In that case, temperature anomalies remained approximately 0.25°C warmer. There is no basis on which to estimate how long it might take for this residual heat to dissipate if it does.

The Pacific Ocean experienced a Great Pacific Climate Shift in 1977, when the Pacific Decadal Oscillation shifted from its cold phase to its warm phase. It appears that the Pacific Ocean might be in the process of shifting back to its cold stage with the start of the current La Nina. The warm phase of the PDO is characterized by more El Nino events than La Nina events, which would tend to leave residual heat from the El Nino events. The cold phase of the PDO is characterized by more La Nina events, which should tend to reduce or remove the residual heat left by the more frequent and stronger El Nino events during the warm phase.

The Great Pacific Climate Shift began before the satellite era, so it is not captured in the UAH graph above. However, it appears that the residual heat remaining after the 1997/1998 and 2015/2016 El Nino events was captured by the UAH anomaly measurements. It will be interesting to see whether the PDO cold mode shift and the current La Nina will remove some or all of the residual heat.

Interview: Climate Change – A Different Perspective with Judith Curry


"My recent interview on the Strong and Free podcast.


I recently did an interview with Christopher Balkaran on his Strong and Free podcast

While I wasn’t previously aware of Balkaran or his podcast, you can see why I agreed to this interview, from these excerpts from the ‘About’ page:

“I created the Strong and Free Podcast to explore news topics by gathering multiple perspectives together and allowing people and organizations to discuss their opinions with detail. This allows for a nuanced conversation. It also means putting aside my own bias to explore these to the fullest. It means making all guests feel welcomed to share their opinions safely, without fear that the host will paint them into a corner, or make them sound incoherent. I want this place to be truly safe. I believe everyone, even those I disagree with, deserve to be treated with respect and to be on the Podcast to share their perspective. It also means having a concrete discussion on issues and determining the best way forward.  As long as we restore thoughtful approaches to the biggest issues of our time our conversations will have deep, valuable meaning. And, we enrich our own opinion.”

We covered a lot of topics that I think will provide good fodder for discussion and debate here.

Here is a transcript of the interview (quicker to read than to listen to the hour long podcast).  I edited the transcript eliminate thousands of ‘like’, ‘you know’, ‘okay’ (I am really a much better writer than speaker).  I also edited to increase overall coherency of what was said.

Focus on the Magma

magma: molten rock material within the earth from which igneous rock results by cooling    Merriam-Webster

The land surfaces of the earth and the bottom surfaces of the earth’s oceans compose the earth’s crust, a layer of rock more than 24,000 feet to as much as 210,000 feet thick. This crust surrounds the upper and lower mantle and the liquid and solid core of the earth. The temperature of the subsurface earth increases with depth from the surface to the solid core, which has a temperature of ~6,000°C.

Magma, or molten rock from the upper portion of the earth’s mantle, most commonly manifests from active volcanos, which exist both on land surfaces and on the ocean floor.

 

Volcanos

 

Recent research suggests that the warming of the West Antarctic Ice Sheet is, at least in part, the result of volcanic activity on the ocean floor below the ice sheet, rather than the effect of global warming.

Recent research also suggests that one of the causes of melting of the Greenland ice sheet is a mantle plume which allows magma to move up through the earth’s crust, rather than the effect of global warming.

There is also sea floor volcanic activity under the arctic sea ice, which might be contributing to diminishing Arctic sea ice extent.

There is currently renewed focus on dry hot rock geothermal energy in conjunction with explosive or hydraulic fracturing. The above graphic shows that there are areas where hot rock is present at relatively shallow depths. This rock can be fractured between two well bores, one used to inject water into the fractured hot rock and the other to transfer the resulting steam to the surface, where it is used to turn a steam turbine generator, then condensed and reinjected. Fracturing dramatically increases the surface area of the dry hot rock which is in contact with the injected water, thus increasing heat transfer to the water and thus increasing the capacity of the well pair and the generating capacity of the electric generator.

The closer the fractured rock area can be located to the mantle or to a magma pool, the higher the temperature of the fractured rock and the higher temperature and pressure of the produced steam.

Also, the closer to the mantle or a magma pool, the more rapidly heat extracted from the fractured rock can be replaced through conduction from the higher temperature source. This suggests that areas near active or even inactive volcanos might be the most productive early targets, since there are likely to be relatively shallow magma pools.

The capacity of the electric generator at a dry hot rock geothermal site is limited by the ability of the rock surrounding the fractured zone to conduct heat back to the fractured zone as it is removed by the steam generation process. Exceeding this capacity would cause the dry hot rock to cool, reducing its ability to transfer heat at temperature to the injected water.

Dry hot rock geothermal generation would be reliable and dispatchable, making it suitable for baseload generation of generation to supplement intermittent wind and solar.

Biden’s energy & climate incompetence on full display

 

"On his very first day in office Biden killed the TC Energy Keystone pipeline project as reported upon by the Wall Street Journal thereby demonstrating his and the Democratic Party’s colossal incompetence and ignorance of energy and climate realities at home and abroad.

His idiotic decision to revoke the permit for the Keystone XL pipeline was noted by the WSJ article as being “a slap at Canada” demonstrating that under his administration “investors that play by U.S. rules” will be subject to arbitrary political whims that represent nothing but Democrats pushing climate alarmism hype in the name of “fighting climate change” with these schemes always being irrelevant to the continuing global CO2 emissions upward climb driven exclusively by the world’s developing nations led by China and India.  

As addressed in the Wall Street Journal article the Keystone pipeline project would have provided for moving up to 830,000 barrels of crude oil per day from Alberta oil sands to U.S. refineries on the Gulf Coast. This long environmentally reviewed project has no material impact on greenhouse gas emissions since this crude will still be extracted in any event whether for U.S. benefit or benefit to other global purchasers that are adversarial to U.S. energy interests.

Shipping this crude using rail or tanker would increase CO2 transportation emissions by between 28% to 42% and with higher leak likelihood. Killing Keystone will strand billions of dollars in Canadian investment alienating a key ally and kill thousands of U.S. jobs including 10,000 American union construction jobs, steel pipe made in the U.S., a 10 million Green Job Training Fund, $500 million for indigenous suppliers and jobs and 100% renewable power to operate the pipeline.

This absurd purely political hand waving action by Biden clearly signals that his administration intends to promote economically damaging energy and climate actions driven completely by irrational claims based upon scientifically unsupported “climate emergency” propaganda." ...

Global Temperature

Model projections of future climate focus on temperature anomalies compared to temperatures in a 30-year climate reference period. The inputs to these models include estimates of climate sensitivity, solar forcing, atmospheric feedback and the future rate of change of atmospheric CO2 and other “greenhouse gases”. The temperatures which form the 30-year climate reference period are estimates, since the actual data have been “adjusted”, “infilled”, “homogenized” and have also been affected by site moves, instrument changes, instrument drift, site deterioration and the Urban Heat Island (UHI) effect. Temperatures more recent than the end of the 30-year climate reference period are also estimates, for the reasons cited above.

Global temperature and temperature anomaly measurements consist of both near-surface temperature measurements over land and sea surface temperatures over the global oceans. The global oceans comprise approximately 71% of the globe’s surface, or more than twice the land surface area. Ocean surface temperatures are also estimates, since the actual data is subject to all of the issues listed above for near-surface land temperatures, with the exception of UHI. Ocean temperature measurements are also sparse compared to near-surface land temperature measurements, so large areas of the global oceans remain unmeasured.

A recent series of articles by Andy May (here, here and here) present and compare ocean surface temperature analyses reported by several agencies involved in climate change analysis, as shown in the graph below. The graphed lines represent calculated ocean temperatures, rather than anomalies, based on the available ocean temperature data. It is important to note that the same measurements form the basis for all of the reported sea surface temperatures over the period shown in the graph. It is also important to note that the two NOAA sea surface temperature estimates differ by ~5.5°C and that the temperature trends represented by the graph lines are significantly different.

The two NOAA graph lines display a very slight upward trend in estimated sea surface temperatures, while HADSST4 shows a downward trend approximately three times as large as the NOAA upward trend. Note that the graph lines are based on temperature estimates reported to two decimal places. The two NOAA graph lines display virtually identical temperature trends, though the temperature estimates differ by ~5.5°C.

The various agencies which report global average temperature anomaly changes combine the anomalies in these sea surface temperature analyses with the anomalies reported for the near-surface land temperatures. The global average temperature anomaly changes are then reported to two decimal place precision and there is great interest in reported year to year changes of 0.01°C. The precision in the anomaly reporting is greater than the accuracy of the underlying data, even after “adjustment”.

The differences in the reported sea surface temperatures are one of the major reasons why global temperature changes are reported as anomalies, rather than absolute temperatures. However, since the reported average temperature for the climate reference period is an estimate and the reported temperature anomaly is also an estimate, reporting annual changes to two decimal place precision is totally unjustified.

The Rational Climate e-Book


"Patrice Poyet has just published a new 431-page eBook entitled, The Rational Climate e-Book, it is free to download here. Dr. Poyet studied geochemistry, remote sensing, and computer science at Ecole des Mines de Paris / Nice University. He received his doctorate in 1986. As an expert computer modeler, he spends much of the book evaluating climate computer models and uncovers their often-unstated underlying assumptions.

English is not Poyet’s first language and some of his phrasing is awkward, but even so, the narrative is compelling and interesting. You stop noticing the odd sentence structure very quickly.

Poyet declares that climate science is now the religion of our time. He then notes that cooling is far more hazardous than warming and quotes a passage from Trevelyan’s A Shortened History of England:

“The last half dozen years of Williams’s reign (i.e., the 1690s) had been the ‘dear years’ of Scottish memory, six consecutive seasons of disastrous weather when the harvest would not ripen. The country had not the means to buy food from abroad, so the people had laid themselves down and died. Many parishes had been reduced to a half or a third of their inhabitants.” (Trevelyan, 1942, p. 432).

This was the coldest period of the Little Ice Age. During this time people not only died due to cold and drought in Scotland, but also in China and many other parts of the world (May, 2020c, pp. 26-27). Poyet, notes as many others have, that the climate models used to supposedly “prove” humans are controlling the global climate have not successfully predicted anything. The lack of predictive skill invalidates them." ...
