Several recent media articles have suggested that even if the US adopted the Green New Deal, or somevariant thereof, which reduced or eliminated US CO2 emissions, the impact on global warming would be “barely measurable”. These ...

China is aggressively pursuing economic development, including construction of numerous coal generating stations, steelmaking facilities and cement kilns. These actions, while inconsistent with the goal of the Paris Accords, are consistent ...

The consensed climate science community has consensed on the hypothesis that anthropogenic CO2 emissions are largely or totally responsible for the recent increase in global average surface temperature. Some even refer to CO2 as the climate...

The consensed climate science community and its animated spokespersons ...

The UNFCCC program objectives center on stabilizing and ultimately reducing global annual CO2 emissions. The Kyoto Accords and the Paris Accords place great emphasis on developed country reductions in annual emissions. However, over the ...

The global climate is changing, as it has over the entire period we have been able to study using a variety of proxies. The consensed climate science community attributes most or all of the climate change which has occurred since 1950 to ...

Many members of the consensed climate science community refer to CO2 as the “control knob” of the climate. Some suggest that increased atmospheric CO2 concentrations resulting from human activities are solely responsible for the...

The graphs below show atmospheric CO2 levels over the past 800,000 years and the past 1020 years. The longer term graph illustrates the cyclical nature of atmospheric CO2 concentrations, varying from a low of approximately 173 ppm to a high...

The effect of CO2 in the globe’s atmosphere on global temperature is the result of the absorption of infrared radiation emitted from the surface of the globe toward space. The quantity of radiation emitted by the surface of the globe ...

“It doesn't matter how beautiful your theory is, it doesn't matter how smart you are.  If it doesn't agree with experiment, it's wrong.” --Richard P. Feynman

In my commentary “Emissions or Equity”, I discussed the philosophical issues regarding global “greenhouse gas” emissions reductions. Now let’s look at the numbers.

The graph below shows the trends in global ...

The first argument of the consensed climate science community is that global “greenhouse gas” emissions must be reduced to avoid a potential future climate catastrophe if the global average near-surface temperature increase ...

The United Nations and several national governments have begun referring to climate change as an existential threat, meaning a threat to the future existence of life on earth. This is a political position intended to draw attention to the ...

Numerous individuals and organizations, including Clintel and the Copenhagen Consensus Center, have calculated the potential effect of US CO2 emissions reductions on global average temperatures or temperature anomalies in the future. These ...

The UN and numerous national governments are promoting the fantasy that the global energy economy can transition to a fossil-fuel-free, all-electric everything energy economy by 2050. In this fantasy, intermittent renewable generation ...

A recent study by a multinational group of scientists has determined that: “From a quarter to half of Earth’s vegetated lands has shown significant greening over the last 35 years largely due to rising levels of atmospheric ...

The Biden Administration has produced a new US INDC (Intended Nationally Determined Contributions) after rejoining the Paris Accords. The new INDC roughly ...

The International Organization for Standards (ISO) promulgates a broad range of standards developed by one or more of its 163 national members and agreed to by the membership. Companies globally are encouraged to adopt these standards in ...

The principal thrust of the UNFCCC and the IPCC has been on climate change mitigation through reductions in global annual emissions of CO2 and other ‘Green House Gases’ (GHGs). The focal point of their efforts has been keeping ...

The earth has experienced roughly cyclical warming and cooling periods over at least the past 800,000 years, accompanied by roughly cyclical increases and decreases in atmospheric CO2. The positive temperature anomalies over this period ...

Most government environmental regulations are based on observations of atmospheric concentrations, exposure durations and adverse health effects. Specific sources of emissions of the pollutants in question are measured individually and the ...

Much has been said and written about the anticipated effects of President Trump’s decision to withdraw the US from the Paris Climate Accord. Several US cities and states have announced their intention to conform to the CO2 reduction ...

The Wall Street Journal recently published an opinion piece by Fred Krupp, the President of the Environmental Defense Fund (EDF). The piece was not accompanied by a disclaimer that the piece was the opinion of Mr. Krupp and did not ...

"A goal without a plan is just a wish." – Antoine de Saint-Exupéry

The Biden Administration has yet to release a plan to reach its stated CO2 emission reduction goals for 2030, 2035 and 2050. However, the ...

Current conversation regarding climate change is largely couched in terms such as “crisis”, “emergency” and “existential threat”. However, the use of these descriptors is political posturing, not ...

The potential for climate change to have adverse effects on the globe, its climate and its population is the subject of great international angst, fomented continuously by the UN secretariat, the UN FCCC, the IPCC, international NGOs, ...

The sensitivity of the global climate to increasing atmospheric CO2 concentrations, specifically to a doubling of atmospheric CO2 from 270 to 540 ppm, is one of the most critical issues in climate science. Sensitivity in combination with ...

This “smart joke” apparently originated in computer science in the ...

The US federal government is supposed to conduct cost / benefit analyses of proposed programs to establish their cost effectiveness. In practice, the costs are often grossly underestimated and the benefits grossly overestimated.

Much has ...

We have much to be thankful for this Thanksgiving and much to be concerned about as well.

We can be thankful that the increased CO2 in the atmosphere has contributed to increased agricultural productivity, which is essential to feed our ...

The Paris Agreement “entered into force on 4 November 2016”. A total of 197 “parties” have “ratified” the Agreement. Ratification of the Agreement is voluntary. Establishment of Nationally Determined ...

The Biden Administration has established targets of reducing US GHG emissions by 50-52% by 2030 and achieving net zero emissions from the electricity sector by 2035. The Administration has not yet publicized a plan to achieve these targets....
