La Niña may be gone, but won't be forgotten soon. Armed with the latest satellite data gathered over the Pacific Ocean, meteorologists are still calling for continued heat in the western U.S. and an unusually active hurricane season. (Reuters)
Methane and other gases may have played a greater role than carbon dioxide from coal and oil burning in warming Earth's surface, according to a recent study. (Fox News, Los Angeles Times)
Researchers have discovered that calcium is good for your health and the Earth's. The amount of calcium in seawater is a direct indicator of carbon dioxide quantities in the atmosphere, and ocean chemistry helps to control the Earth's warmth. (Daily Californian, Excite News)
According to a recent study, one third of the Earth's wildlife and vegetation and is under threat from global warming and could disappear or change beyond recognition by the end of this century. (Reuters, The New York Times, CNN)
Satellite data shows an usually early drop in the level of upper level ozone over the Antarctic. (ABC News, Reuters, MSNBC, Associated Press)
A warmer world may not be our destiny, based on the latest research from James Hansen's study of greenhouse gases that cause increasing global temperatures. (The New York Times)
An editorial cites both bad news and good news on global warming, from open water at the North Pole to James Hansen's report stating "It may be more practical to slow warming than is sometimes assumed." (The Washington Post)
Open water at the top of the world isn't evidence that the North Pole is melting, polar scientists say. The singular hole at the top of the world is likely just a temporary opening. (The Dallas Morning News)
As the Earth's climate heats up, the difference between the warm surface and colder upper air will increase, triggering more violent weather, such as thunderstorms that spark fires. (The Los Angeles Times)
Climate fluctuations have been noted throughout history. For 400 years, the Earth's climate warmed, allowing Vikings to settle in Greenland. Then the earth cooled into a "Little Ice Age" which lasted some 400 to 700 years, possibly ending in 1900. (Christian Science Monitor)
Forecasters blame this month's freakish snow storm in Britain and unusual weather in the United States on a change in the jet stream, caused by La Niña. (Fox News)
Representatives from 180 countries who signed the Kyoto Protocol will meet in France in September to work out an international agreement to curb greenhouse gas emissions. (Reuters)
Scientists says that Britain faces the threat of becoming a tropical island unless efforts are made to fight global warming. (Nick Nuttall, The London Times)
Arctic scientists have reviewed 40 years of polar research that shows consistency with climate change model forecasts. (Peter N. Spotts, Christian Science Monitor)
British researchers have concluded that carbon dioxide levels in Earth's atmosphere are higher than they have been in 20 million years. (BBC News)
Research shows that ragweed and other plants produce significantly more pollen as carbon dioxide increases in the atmosphere, greatly affecting allergy sufferers. (Associated Press, Reuters, USA Today)
After four years of inundating a forest with carbon dioxide, the principle greenhouse gas, researchers have noticed that some forests have thrived. (ABC News)
Researchers suggest a global effort to reduce air pollution, especially tropospheric ozone and black carbon, would slow global warming. (CNN, The London Daily Telegraph and the Environmental News Network)
Australian scientists are working on a plan to reduce greenhouse gases in the atmosphere by injecting excess quantities of carbon dioxide underground. (Reuters)
In a study of desertification in the southwestern United States, remote sensing imagery has documented an invasion of mesquite bushes into a former grassland. (ScienceDaily.com)
Scientists say that the Atlantic coastal United States, the Caribbean and Central America may face the increased threat of major hurricanes for another 20 or 30 years, and warmer Atlantic Ocean temperatures may be a main contributor. (ABC News)
Researchers suggest that thriving microbes consume trapped carbon from dead vegetation and soils underneath glaciers, which would be released as carbon dioxide and methane during transitions between ice ages and interglacial periods. (New Scientist)
The National Hurricane Center lowered its yearly estimate of hurricanes in the Atlantic Ocean, but it will still be a season with more hurricanes than normal. They forecast 11 named storms, 3 of them major hurricanes. (Reuters)
The winter of 1999-2000 brought relatively little snow to parts of the North American continent, according to data from NASA's Terra satellite snow melted early compared to normal years. (Robinson Shaw, Environmental News Network and Craig Linder, States News Service)
Hurricane forecaster William Gray has revised his forecast for this hurricane season because of the fading of the La Nina event. Gray now predicts 11 named storms, 7 of them hurricanes, 3 of those major hurricanes. (Associated Press)
The United States is proposing incentives to countries that plant trees and farm in ways that absorb carbon dioxide in order to attain the emissions standards set by the Kyoto Protocol. (Andrew C. Revkin, The New York Times)
A deep ocean current originating near Antarctica is influencing marine life nearly halfway around the world, and may be a key to understanding climate change. (MSNBC News)
Oceanographers discovered long-term shifts in the temperature of the Pacific Ocean, which could help scientists better predict climate change. (Reuters)
Research has shown that ozone, a major constituent of smog, directly effects the genes associated with the aging process in plants. The study concluded that ozone accelerates a plant's aging process. (ScienceDaily.com)
