Climate Likely to Be on Hotter Side of Projections


Climate Likely to Be on Hotter Side of Projections

Surface relative humidity data from the Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua spacecraft were used to analyze how well leading global climate models reproduce observed relative humidity in Earth's tropics and subtropics.

A new NASA-funded study by the National Center for Atmospheric Research, Boulder, Colo., finds climate model projections that show a greater rise in global temperature are likely to prove more accurate than those showing a lesser rise. The findings, published today in the journal Science, could provide a breakthrough in the longstanding quest to narrow the range of global warming expected in coming decades and beyond.
