H2O decreasing while CO2 rises !

Dire predictions of global warming all  rely on positive feedback from  water vapor. The argument goes that as surface temperatures rise so  more water will evaporate from the oceans thereby amplifying temperatures because H2O itself is a strong GHG.  Climate models … Continue reading

Trends in Atmospheric Water Vapour

The basis of IPCC predictions is that any moderate warming caused by increased CO2 levels is enhanced by more evaporation from the oceans. Water vapour is itself a strong greenhouse gas and this increase results in a large “positive feedback” … 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
