Volcanoes Have Shifted Asian Rainfall

Powerful volcanoes potential to shift rain patterns

Scientists have long known that large volcanic explosions can affect the weather by spewing particles that block solar energy and cool the air. Some suspect that extended “volcanic winters” from gigantic blowups helped kill off dinosaurs and Neanderthals. In the summer following Indonesia’s 1815 Tambora eruption, frost wrecked crops as far off as New England, and the 1991 blowout of the Philippines’ Mount Pinatubo lowered average global temperatures by 0.7 degrees F — enough to mask the effects of manmade greenhouse gases for a year or so.

Soybean sprouts struggling in dry conditions. Biologists have now solved the structure of a critical molecule that helps plants survive during droughts.

A team of biologists in California led by researchers at The Scripps Research Institute and the University of California (UC), San Diego has solved the structure of a critical molecule that helps plants survive during droughts. Understanding the inner workings of this molecule may help scientists design new ways to protect crops against prolonged dry periods, potentially improving crop yields worldwide, aiding biofuels production on marginal lands and mitigating drought’s human and economic costs.

Acidic Clouds Nourish World’s Oceans

Water droplets in clouds generally form around dust and other particles. When clouds evaporate, as they often do naturally, the surface of the particle can become very acidic. This is especially true where the air is polluted.

Scientists at the University of Leeds have proved that acid in the atmosphere breaks down large particles of iron found in dust into small and extremely soluble iron nanoparticles, which are more readily used by plankton.

Tornado Threat Increases As Gulf Hurricanes Get Larger

Large tornadoes occurring near gulf coast.

Tornadoes that occur from hurricanes moving inland from the Gulf Coast are increasing in frequency, according to researchers at the Georgia Institute of Technology. This increase seems to reflect the increase in size and frequency among large hurricanes that make landfall from the Gulf of Mexico.
