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. Because CO2 in the atmosphere is long lived, it can effectively lock the Earth and future generations into a range of impacts, some of which could become very severe.

(Reuters) - The world's emissions of carbon dioxide from burning coal, oil, and natural gas should rise 43 percent by 2035 barring global agreements to reduce output of the gases blamed for warming the planet, the top U.S. energy forecaster said on Tuesday. Global emissions of carbon dioxide from the fossil fuel sources should rise from 29.7 billion tonnes in 2007 to 42.4 billion tonnes in 2035, the Energy Information Administration said in its annual long-term energy outlook.

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 si

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 market was swamped by excess supply. Energy prices reflected this shift: oil peaked at $144 per barrel in July, then fell to $34 per barrel in December.2 Continuing a decade-long trend, most of the growth was in the... region.
