Climate Change

"Midwestern Democrats, who want duties placed on countries who don't limit greenhouse gas emissions, are at odds with Obama."

"July was the hottest the world's oceans have been in almost 130 years of record-keeping. ... Meteorologists said there's a combination of forces at work this year: A natural El Nino system just getting started on top of worsening man-made global warming, and a dash of random weather variations. The resulting ocean heat is already harming threatened coral reefs. It could also hasten the melting of Arctic sea ice and help hurricanes strengthen."

"Beetles and fire, twin plagues, are consuming northern forests in what scientists say is a preview of the future, in a century growing warmer, as the land grows drier, trees grow weaker and pests, abetted by milder winters, grow stronger. Dying, burning forests would then only add to the warming."

"Mexico is suffering from its driest year in 68 years, killing crops and cattle in the countryside and forcing the government to slow the flow of water to the crowded capital."

"Since the mid-1990s, hurricanes and tropical storms have struck the Atlantic Ocean with unusual frequency -- or have they? Two new studies suggest that the situation may not be so clear."

"Glaciers on the iconic Teton Range are shrinking, researchers say, joining a growing list of glaciers in North America and beyond that are losing their surface area and potentially reducing the water supply for nearby regions."

"As the hot days in Texas get even hotter, it may just be too much for some birds and fish. From the American goldfinch to the gray snapper, some species have been moving north for years, searching for cooler ground. And their quest may someday lead them to migrate out of the state -- forever -- especially if climate change continues to make Texas warmer, as predicted."

"The latest round of preparatory talks for the U.N. climate conference concluded today with negotiators lamenting that the languid pace of talks could mean there won't be a deal on emissions in Copenhagen this December."

"Leading figures from the French wine and food industries are urging their government to push for a strong global agreement at a United Nations climate summit in Copenhagen in December, warning that failure to cut greenhouse gases will devastate their sector."
