Future Temperature Predictions Based on Global Circulation Models

This study leverages data from the IPCC DDC web tool to present temperature anomalies projected for the late 21st century, comparing anomalies from 2080-2099 against the 1961-1990 baseline. Utilizing NASA's GISS-ER model, it outlines three scenarios based on IPCC SRES guidelines: Worst Case (A2), Moderate Case (A1B), and Best Case (B1). The analysis provides January and July temperature forecasts, allowing for an understanding of potential climate outcomes under different emission scenarios.

Presentation Transcript

  1. Global Circulation Model Predictions of Future Temperatures • Maps compiled from the IPCC DDC web tool that allows access to GCM modeling results • NASA’s GISS ER model used for all simulations • Temperature anomalies presented as difference between late 21st century temperatures (2080-2099 average) and the 1961-1990 30-year average baseline. • IPCC SRES Scenarios presented as: • Worst case (A2) • Moderate case (A1B) • Best case (B1) • Note – other scenarios can be found that give worse “worst” case and better “best” case predictions, but the ones chosen here are commonly used
