The two strongest potentially credible constraints, and conclusions
In Part 1 of this article the nature and validity of emergent constraints[1] on equilibrium climate sensitivity (ECS) in GCMs were discussed, drawing mainly on the analysis and assessment of 19 such constraints in Caldwell et al. (2018),[2] who concluded that only four of them were credible. An extract of the rows of Table 1 of Part 1 detailing those four emergent constraints is given below.[3]

In the mid-1900’s many scientists were suggesting the Earth was cooling. Now scientists are forecasting global warming. Indeed, instrumental data shows global temperatures warmed by approximately 1-degree C during the past 165+ years. With warming rates of 0.5 to over 1.3 degrees C per century this has caused considerable alarm for many. This recent warming is commonly attributed to increasing greenhouse gases, primarily CO2.
This post examines natural paleoclimate trends and simple characteristics of past and present climate cycles at different time scales.

Little is known about the ice age human occupation of the Pacific Coast of Canada. Here we present the results of a targeted investigation of a late Pleistocene shoreline on Calvert Island, British Columbia. Drawing upon existing geomorphic information that sea level in the area was 2–3 m lower than present between 14,000 and 11,000 years ago, we began a systematic search for archaeological remains dating to this time period beneath intertidal beach sediments (…)

German CO2 equivalent emissions refuse to budge 10 straight years running, despite hundreds of BILLIONS invested in green energies.
As we have been hearing recently, global CO2 emissions continue their steady climb, despite the trillions of dollars committed to green energy sources worldwide and efforts to curb CO2 emissions.

Just as a follow up to my earlier post on German GHG emissions, I have looked at the comparative energy consumption figures for 2009 and 2016 (…)
