WASHINGTON — Choices made now about carbon dioxide emissions reductions will affect climate change impacts experienced not just over the next few decades but also in coming centuries and millennia, says a new report from the National Research Council.

WASHINGTON/PARIS (Reuters) - Governments will have to grapple with sharply higher upfront costs to deploy clean energy technologies and halve carbon emissions by 2050, the International Energy Agency said on Thursday.

UNITED NATIONS — Rich and poor nations need a "clean energy revolution" in order to cut greenhouse gas emissions responsible for global warming, UN chief Ban Ki-moon said here Wednesday.

Climate scientists have long warned that global warming could unlock vast stores of the greenhouse gas methane that are frozen into the Arctic permafrost, setting off potentially significant increases in global warming.

World production of fossil fuels-oil, coal, and natural gas-increased 2.9 percent in 2008 to reach 27.4 million tons of oil equivalent (Mtoe) per day.1 (See Figure 1.) In the first half of the year, producers strained to meet global demand, but when the recession took hold later in the year the m
