CMIP3 Models Versus 20th Century Land Surface Temperature Anomalies

Posted on December 20, 2011 by Bob Tisdale

I was writing the summary post for my recent series that compare observed Global Surface Temperatures to the IPCC and CMIP3 Climate Model outputs when I realized I had not presented Land Surface Temperature Anomaly comparisons. COMPARISONS This post illustrates … Continue reading →

IPCC Models Versus Sea Surface Temperature Observations During The Recent Warming Period

Posted on December 19, 2011 by Bob Tisdale

OVERVIEW This post compares satellite-based Sea Surface Temperature (SST) anomalies to the hindcasts and projections of the multi-model mean of CMIP3 models. CMIP3 is the archive the IPCC used as the source of their models for AR4. The period being … Continue reading →

Mid-December 2011 SST Anomaly Update

Posted on December 19, 2011 by Bob Tisdale

NINO3.4 NINO3.4 Sea Surface Temperature (SST) anomalies (a commonly used El Niño-Southern Oscillation Index) are varying near the threshold of a moderate La Niña. They’ve been bouncing back and forth across -1.0 for a few weeks. For the week centered … Continue reading →

The IPCC AR4 Models Of 20th Century Surface Temperatures With And Without Anthropogenic Forcings

Posted on December 16, 2011 by Bob Tisdale

This is a quick post. It reinforces one of the points made repeatedly in recent comparisons of the observed rise in Global Surface Temperatures during the 20thCentury and of those hindcast by the Multi-Model Mean of the models used by … Continue reading →

It Really Should Go Without Saying, BUT…

Posted on December 14, 2011 by Bob Tisdale

OVERVIEW In a good number of posts over the past few months, we have discussed and illustrated how poorly the coupled ocean-atmosphere climate models used by the Intergovernmental Panel on Climate Change (IPCC) in their 4th Assessment Report (AR4) simulate … Continue reading →
