A small group of Himalayan glaciers grew in size when the earth became hotter 9,000 years ago, new research shows.

Global warming could actually chill down North America within just a few decades, according to a new study that says a sudden cooling event gripped the region about 8,300 years ago.

Sea Levels Rose as Much as Two Feet This Summer in U.S. East

Sea levels rose as much as 2 feet (60 centimeters) higher than predicted this summer along the U.S. East Coast, surprising scientists who forecast such periodic fluctuations. The immediate cause of the unexpected rise has now been solved, U.S. officials say in a new report (hint: it wasn't global warming). But the underlying reason remains a mystery.

New Carbon Dioxide Data Helps Unlock The Secrets Of Antarctic Formation

The link between declining CO2 levels in the earth's atmosphere and the formation of the Antarctic ice caps some 34 million years ago has been confirmed for the first time in a major research study.

Summer Temperatures Lower Than Normal Over Most of US

Global warming doesn’t necessarily mean that temperatures are rising every year, everywhere. Superimposed on global trends are local and regional climate effects that may differ from global trends. For example, the average June-August 2009 summer temperature for the contiguous United States was below average – the 34th coolest on record, according to a preliminary analysis by NOAA’s National Climatic Data Center in Asheville, N.C. August was also below the long-term average. The analysis is based on records dating back to 1895.

Another Factor that Impacts our Climate
September 13, 2009 11:09 AM - R. Greenway, ENN

UCLA atmospheric scientists have discovered a previously unknown basic mode of energy transfer from the solar wind to the Earth's magnetosphere. The research, federally funded by the National Science Foundation, could improve the safety and reliability of spacecraft that operate in the upper atmosphere. "It's like something else is heating the atmosphere besides the sun. This discovery is like finding it got hotter when the sun went down," said Larry Lyons, UCLA professor of atmospheric and oceanic sciences and a co-author of the research, which is in press in two companion papers in the Journal of Geophysical Research.

German ships successfully make "Arctic Passage"

Two German cargo ships have successfully navigated across Russia's Arctic-facing northern shore from South Korea to Siberia without the help of icebreakers, the shipping company said. The two merchant ships belonging to Beluga Shipping Gmbh were able to make the cost-saving voyage by the fabled Northeast Passage because of the reduction in the polar ice cap due to global warming, the company said.

Arctic Ecosystems Changing, May be Irreversible

The dramatic changes sweeping the Arctic as a result of global warming aren't just confined to melting sea ice and polar bears — a new study finds that the forces of climate change are propagating throughout the frigid north, producing different effects in each ecosystem with the upshot that the face of the Arctic may be forever altered.

India Could Halve Emissions Growth, at a Cost
September 10, 2009 07:32 AM - Anna da Costa, Worldwatch Institute

Growth in India's carbon emissions could be nearly halved by the year 2030 through the use of known practices and technologies, according to a new report from McKinsey & Company. Through a "step-change in...efforts to lower emissions," India's carbon output could grow from 1.6 billion tons in 2005 to only 2.8 billion tons in 2030 as the country's population expands and its economy develops, the report said. This is down from a previously projected 5-6 billion tons for 2030.

Salazar says U.S. climate bill high on agenda

Despite Washington's nearly single-minded focus on healthcare reform, the Obama administration still expects the U.S. Senate to pass climate change legislation, Interior Secretary Ken Salazar said on Tuesday.
