This remarkable colonization is having a beneficial impact on climate change. As the blooms die back phytoplankton sinks to the sea-bed where it can store carbon for thousands or millions of years.

Researchers examined climate changes that have taken place over the past 800,000 years, and discovered that the melting icebergs in the North Atlantic and changes in the El Niño Southern Oscillation have a great influence on the intensity of monsoon rains.

Each of those billion lightning flashes produces a puff of nitrogen oxide gas (NOx) that reacts with sunlight and other gases in the atmosphere to produce ozone. Using data gleaned from aircraft observations and satellites, NASA scientists recently took steps toward a better global estimate of lightning-produced NOx and found that lightning may have a considerably stronger impact on the climate in the mid-latitudes and subtropics.

A new study shows that corals spawn when regional wind fields are light. When it is calm, the eggs and sperm have the chance to unite before they are dispersed.

The study found that almost any change that makes land cover less "green" contributes to warming. A perhaps less intuitive finding is that conversion of any land to agricultural use results in cooling, even land that was previously forested.

There are some doubts, considering the planet's atmosphere is only 1 percent as dense as that of the Earth. Mars, however, definitely has clouds, drastically low temperatures and out-of-this-world dust storms. A professor of atmospheric sciences now hopes to analyze and forecast Martian weather.

The findings indicate a major cause of this ice loss is very likely to be the rise in global temperatures.

Their findings have potentially important implications for understanding global climate, both past and future.

And they've been aided by ever more sophisticated computer models that make estimating the relative impact of each type of pollutant more reliable. Yet the complexity of nature -- and the models used to quantify it -- continues to serve up surprises. The most recent? Certain gases that cause warming are so closely linked with the production of aerosols that the emissions of one type of pollutant can indirectly affect the quantity of the other. And for two key gases that cause warming, these so-called "gas-aerosol interactions" can amplify their impact.

This is considerably south of the inhospitable habitat than one usually imagines for mammoths, and for the characteristically dry and cold climate that prevailed during the ice ages in the north of Eurasia.

Perhaps ironically, these volcanoes first caused global warming -- by releasing massive amounts of carbon dioxide into the atmosphere. When they stopped erupting, Earth's climate was thrown off balance, and the ice age began.

Researchers argue that policymakers should plan a summit now to look at these pollutants, which range from soot to ozone and methane, because they will be more complicated to regulate than is the case with carbon dioxide.
