Coffee yields from Columbia are declining and prices are rising, because of warmer, wetter weather. Many scientists think global warming is responsible.

The extent of Arctic sea ice cover reached a record low this winter, tying the record low mark set in the winter of 2005, according to the National Snow and Ice Data Center. Scientists consider the decline of sea ice to be a sign of manmade global warming.

"Democrats have attempted to get Republicans to confront the science on climate change, in an effort to halt moves to block regulation of greenhouse gas pollution. But it's not clear that the appeal to reason worked."

Henry Waxman (D-CA), ranking member of the House Energy Committee, speaking Monday at the Center for American Progress, said "The Republicans in Congress have become the party of science deniers, and that is profoundly dangerous."

Besides being a keystone of the ocean ecosystem, coral reefs are of huge commercial value. But they are seriously threatened by floods, runoff, rising ocean temperatures and acidity which are all symptoms of our fossil-fuel economy.

Global warming is causing dramatic changes in the Arctic Ocean. The earlier melting of annual ice is causing the regular spring blooms of plankton to peak up to 50 days earlier -- possibly disrupting the entire ecosystem of fish, shellfish, birds, and marine mammals that depend on the plankton.

"A NASA satellite designed to study aerosols' influence on climate and measure solar energy failed to reach orbit [Friday] morning. The crash marks the second time in two years that a NASA climate satellite has failed to launch."

"The Department of Energy said on Thursday it has offered a conditional $102 million loan guarantee to support a wind farm in Maine. The financial aid will support the Record Hill wind project, a 50.1 megawatt wind power plant and transmission line in Maine."

"Environmental activist Tim DeChristopher knew what he was doing when he made $1.8 million in false oil and gas drilling bids at a federal auction. He knew he couldn't possibly pay for them. And he knew he could end up behind bars. But he did it for the cause. On Thursday, a federal jury convicted him on two felony counts of interfering with and making false representations at a government auction."

Republicans and some coal-state Democrats are trying to stop EPA from regulating greenhouse gas emissions, saying it will hurt jobs. But several economists point to evidence from past history and other nations which suggests that the exact opposite is the case.
