NASA Study Links "Smog" to Arctic Warming

In a global assessment of the impact of ozone on climate warming, scientists at the NASA Goddard Institute for Space Studies (GISS), New York, evaluated how ozone in the lowest part of the atmosphere (tropospheric ozone) changed surface temperatures over the past 100 years. Using the best available estimates of global emissions of the various gases that produce tropospheric ozone, the GISS computer model study reveals how much this single air pollutant and greenhouse gas has contributed to warming in specific regions of the world.

Impact of Climate Warming on Polar Ice Sheets Confirmed

03.08.06

In the most comprehensive survey ever undertaken of the massive ice sheets covering both Greenland and Antarctica, NASA scientists confirm climate warming is changing how much water remains locked in Earth's largest storehouse of ice and snow.
