Part 2 – Satellite-Era Sea Surface Temperature Versus IPCC Hindcast/Projections

THE INDIAN AND ATLANTIC OCEANS

INTRODUCTION

This post is a continuation of Part 1 – Satellite-Era Sea Surface Temperature Versus IPCC Hindcast/Projections.  It examines the differences between multi-model mean of the IPCC 20C3M (Hindcast)/SRES A1B (Projection) for Sea Surface Temperatures and the observations using Reynolds OI.v2 Sea Surface Temperature (SST) anomalies, a satellite-based SST dataset.  Part 1 covered the global oceans and the Pacific. This post discusses the Indian and Atlantic Oceans.  ….

….That is, since 1982, the Sea Surface Temperatures for the Indian, North and South Pacific, and South Atlantic have warmed much more slowly than projected by the models. The models have failed to capture the higher rise in North Atlantic SST anomalies because they do not include the additional natural variability that’s attributable to the Atlantic Multidecadal Oscillation.
