The Watchers Share Email 6109 Email Share A leading Chinese meteorologist says the country will employ more rainmaking technology and make better use of it in the next five years. Some 560,000 manipulations of the weather have been conducted since 2002 using aircraft, rockets and projectiles carrying dry ice or silver iodide particles to stimulate rainfall, resulting with release of 489.7 billion tons of rain and saved about $10.4 billion in economic losses the China Meteorological Administration reported. China started with weather modification program in 1958. For the 2008 Olympics, China had 30 airplanes, 4,000 rocket launchers, and 7,000 anti-aircraft guns to stop rain.

The methane has been trapped by ice, but is able to escape as the ice melts. Writing in the journal Nature Geoscience, the researchers say this ancient gas could have a significant impact on climate change.
The Watchers Share Email 41 Email Share The springtime began to feel more like summer for most of North America. March 2012 saw thousands of daily temperature records fall in the contiguous United States (often called the “lower 48”), and the entire month was the warmest March in a temperature record that dates back to 1895. For the month, the eastern two-thirds of the United States, as well as the Canadian provinces of Ontario, Quebec, and Manitoba, saw temperatures in the GISS map approaching as much as 10 degrees Celsius (18 degrees Fahrenheit) above normal (deepest reds on the map). Temperatures were similarly extreme in the Arctic Ocean around Svalbard, the Barents Sea, and the Kara Sea. Far eastern Siberia, Alaska, and northwestern North America were significantly colder, while much of Europe and western Russia were warmer than normal (following a much colder February).

"Wind Map" on March 29, 2012 at 9:00pm ET. (Credit: Screenshot by Dara Kerr/CNET) Two technology artists who head Google's "Big Picture" visualization research group debuted a new project this week that shows a time-lapse animation of wind speeds across the U.S.
An invisible, ancient source of energy surrounds us—energy that powered the first explorations of the world, and that may be a key to the future. This map shows you the delicate tracery of wind flowing over the US. The wind map is a personal art project, not associated with any company. We've done our best to make this as accurate as possible, but can't make any guarantees about the correctness of the data or our software. Please do not use the map or its data to fly a plane, sail a boat, or fight wildfires :-)
