Decelerating Global Warming !

Shown below is an updated version of the 2007 IPCC graph which formed the basis for the claim that AGW was accelerating. The same  analysis repeated in 2012  now shows a deceleration in warming, which  demonstrates just how dubious the original … Continue reading

Thermal inertia and climate feedbacks

Abstract: This post studies the time lag in global  warming following incremental increases in CO2 forcing. It uses a GCM [1] to parameterize these  ”inertia” effects which are mainly due to  slow ocean warming and ice melting. The  Mauna Loa … Continue reading

Global exaggeration ?

I rather suspect that climate scientists have consciously or sub-consciously tended to exaggerate future scenarios in order to boost AGW in the public consciousness as the biggest single threat to mankind. On balance, it now seems far more likely that … Continue reading

Climate sensitivity reduces by ~20% if using the correct TSI value

The latest value of TSI is 1360.8 W/m^2  (ref. Kopp & Lean 2011) measured by SORCE TIM. This is considerably lower than the ~1367 W/m^2  based on previous data that is used in most GCM models, including GISS model II. This lower … Continue reading

Getting to grips with GISS GCM

I have downloaded the GISS GCM Model II [1] and have begun to investigate it. Since all the predictions of future AGW depend on the results from such models I decided I really needed to understand just how they work. … Continue reading
