An Engineer’s Observations
  • 11/22/16 at 8:21 AM
  • Climate Change
  • Ed Reid

Several aspects of government-funded climate science appear both curious and disturbing. The current level of government funding of climate science is certainly adequate to support rigorous scientific investigation, data gathering and ...

Analytical Caution

  • Climate Change
  • Ed Reid

The previous commentaries on coincidence and causation regarding temperature anomalies and sea level referred to two interactive composite graphs (here and here). These graphs each combine paleoclimatic estimates of historical conditions ...

  • Coincidence: the occurrence of events that happen at the same time by accident but seem to have some connection, Merriam-Webster
  • Causation: the act or agency which produces an effect, Merriam-Webster

Climate Sensitivity

The IPCC has recently lowered its estimated range of climate sensitivity to a doubling of atmospheric CO2 concentration. The IPCC AR6 estimated range is 2.5-4.0, with an expected value of 3.0. However, studies ...

Sea Level Change

  • Climate Change
  • Ed Reid

One of the greatest climate change concerns expressed by low lying coastal and island nations is the threat which would result from rising sea levels, caused by a combination of thermal expansion and the melting of glacial and land ice. ...

Sea Level Graphs

The graph below plots global sea level over the past approximately 800,000 years. Note the cyclical nature of sea level over that period. Sea level ranges from a high of +11 meters to a low of -133 meters. The low levels are associated with...

Sea Level Rise “Settled Science”

  • Climate Change
  • Ed Reid

“There is a total absence of data supporting the notion of a present sea level rise; on the contrary all available facts indicate present sea level stability. On the centennial timescale, there was a +70 cm high level in the 16th and ...

Signal / Noise Ratio (Sea Level)

  • Ed Reid

“Signal-to-noise ratio (abbreviated SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise.”,


Another of the ...
