"Members of the Senate Agriculture Committee will vet options this week for the sweeping energy and climate bill, which they are expected to play a significant role in shaping."
Secretary of State Hillary Clinton's visit to India will bring a $10-billion deal to sell U.S. nuclear reactors to that country -- but probably not break the impasse on whether India will join other nations trying to limit greenhouse emissions.
The UN-based International Maritime Organisation (IMO), which regulates ocean shipping, agreed Friday to voluntary proposals aimed at cutting carbon emissions.
"A new burst of coal-fired power plant construction now underway -- the largest in decades -- will put 43 new coal plants on American soil in the next five years, and all of them will escape the performance standards written into the climate bill now moving through Congress."
"BEIJING -- Top U.S. officials on Wednesday left open the possibility that China might not have to accept a hard cap on its greenhouse gas emissions under a new global climate change treaty."
"A dramatic warming of the planet 55 million years ago cannot be solely explained by a surge in carbon dioxide levels, a study shows, highlighting gaps in scientists' understanding of impacts from rapid climate change." One implication is that the current warming episode could prove worse than now predicted, as models may not fully account for feedback mechanisms that amplify warming.
"During the past few centuries the near-equatorial band of dense precipitation that supplies freshwater to nearly one billion people has migrated hundreds of miles to the north —most likely because of a warming world, scientists say."
"In addition to weakening Earth’s natural shield against excessive radiation levels, ozone depletion above Antarctica has significantly dampened the Southern Ocean’s ability to absorb atmospheric CO2 and has accelerated acidification of southern polar waters, new research shows."
The monsoon arrived late and weak in India this year -- a phenomenon some attribute to climate change. As it ponders drought and crop failure, India continues to insist that rich nations must solve the climate problem without its help.
"The world's leading industrial nations tentatively agreed Wednesday to try to prevent global temperatures from rising above a fixed level, after a more far-reaching proposal to slash production of greenhouse gases fizzled... ."
"Hydrofluorocarbons ... are ... many thousands of times more potent than CO2 as climate warming agents, and scientists say their spread could become as much as 50 percent of the global greenhouse gas problem by 2050. Yet the public is barely aware of the issue, and as the White House works to hammer out its policy, it seems to want to keep it that way."
