- Even Dust Particles Have A Ripple Effect On Climate Far Away
When a small pebble drops into a serene pool of water, it causes a ripple in the water in every direction, even disturbing distant still waters. NASA researchers have found a similar process at work in the atmosphere: tiny particles in the air called aero ...

- A NASA Space Sleuth Hunts The Trail Of Earth's Water
For the first time, NASA scientists have used a shrewd spaceborne detective to track the origin and movement of water vapor throughout Earth's atmosphere. This perspective is vital to improve the understanding of Earth's water cycle and its role ...

- From Icehouse To Hothouse: Melting Ice And Rising CO2 Caused Climate Shift
Three hundred million years ago, Earth's climate shifted dramatically from icehouse to hothouse, with major environmental consequences. That shift was the result of both rising atmospheric carbon dioxide concentrations and the melting of vast ice she ...

- Kent Moore: Physicist, Hurricane Rider
Science doesn’t always happen at a lab bench. For University of Toronto Mississauga physicist Kent Moore, it happens while strapped into a four-point harness, flying head-on into hurricane-force winds off the southern tip of Greenland. Moore, chair of the ...

- The Insides Of Clouds May Be The Key To Climate Change
As climate change scientists develop ever more sophisticated climate models to project an expected path of temperature change, it is becoming increasingly important to include the effects of aerosols on clouds, according to Joyce E. Penner, a leading atmo ...

- UW Scientists Cite Evidence That Global Warming Fuels Stronger Atlantic Hurricanes
Atmospheric scientists have uncovered fresh evidence to support the hotly debated theory that global warming has contributed to the emergence of stronger hurricanes in the Atlantic Ocean. The unsettling trend is confined to the Atlantic, however, and does ...

- Hurricane Can Form New Eyewall And Change Intensity Rapidly
Data collected in 2005 from Hurricane Rita is providing the first documented evidence that rapid intensity changes can be caused by clouds outside the wall of a hurricane's eye coming together to form a new eyewall. Hurricanes can gain or lose intens ...

- Global 'Sunscreen' Has Likely Thinned- NASA
A new NASA study has found that an important counter-balance to the warming of our planet by greenhouse gases – sunlight blocked by dust, pollution and other aerosol particles – appears to have lost ground. The thinning of Earth’s "sunscreen" of ...

- Global Temperature-- Politics Or Science?
The entire debate about global warming is a mirage. The concept of ‘global temperature’ is thermodynamically as well as mathematically an impossibility, says professor at The Niels Bohr Institute, University of Copenhagen, Bjarne Andresen who has analyzed ...

- Scientists Derive Bottom-up Air-sea Momentum Transfer Under Major Hurricane
Scientists at the Naval Research Laboratory- Stennis Space Center (NRL-SSC) have directly derived the air-sea momentum exchange at the ocean interface using observed ocean currents under Hurricane Ivan and determined that it decreases when winds exceed 32 ...
