Deep Oceans May Mask Global Warming for Years at a Time

Computer simulations of global climate lead to new conclusions.Earth's deep oceans may absorb enough heat at times to flatten the rate of global warming for periods of as long as a decade--even in the midst of longer-term warming. This according to a new analysis led by scientists at the...

New Method to Measure Snow, Soil Moisture With GPS May Benefit Meteorologists, Farmers

A research team led by the University of Colorado at Boulder has found a clever way to use traditional GPS satellite signals to measure snow depth as well as soil and vegetation moisture, a technique expected to benefit meteorologists, water resource managers, climate modelers and farmers.The...

Do Dust Particles Curb Climate Change?

Meteorologists urge new research on the influence of aerosols.A knowledge gap exists in the area of climate research: for decades, scientists have been asking themselves whether, and to what extent man-made aerosols, that is, dust particles suspended in the atmosphere, enlarge the cloud cover and...

Global Warming May Dent El Niño’s Protective Shield from Atlantic Hurricanes, Increase Droughts Elsewhere

MIAMI -- El Niño, the periodic eastern Pacific phenomenon credited with shielding the United States and Caribbean from severe hurricane seasons, may be overshadowed by its brother in the central Pacific due to global warming, according to an article in the September 24 issue of the...

Air pollution is reducing light rains in China

Air pollution in eastern China during the last 50 years has led to a reduction in the amount of light rainfall of almost a quarter. This is revealed by an international study conducted with support from the University of Gothenburg, Sweden. There is a risk that the consequences will be increased...

Lightning's Mirror Image ... Only Much Bigger

Scientists capture one-second image of huge lightning flowing 40 miles upward from stormWith a very lucky shot, scientists have captured a one-second image and the electrical fingerprint of huge lightning that flowed 40 miles upward from the top of a storm.These rarely seen, highly charged...

Harbingers of increased Atlantic hurricane activity identified

University Park, Pa. -- Reconstructions of past hurricane activity in the Atlantic Ocean indicate that the most active hurricane period in the past was during the "Medieval Climate Anomaly" about a thousand years ago when climate conditions created a "perfect storm" of La...

Beating the radar: Getting a jump on storm prediction

Satellite observation of cloud temperatures may be able to accurately predict severe thunderstorms up to 45 minutes earlier than relying on traditional radar alone, say researchers at the University of Wisconsin-Madison Space Science and Engineering Center.Scientists from the Cooperative...

Dust Plays Larger Than Expected Role In Determining Atlantic Temperature

MADISON - The recent warming trend in the Atlantic Ocean is largely due to reductions in airborne dust and volcanic emissions during the past 30 years, according to a new study.Since 1980, the tropical North Atlantic has been warming by an average of a quarter-degree Celsius (a half-degree...
