Latest Abrupt climate change Stories
Two abrupt and drastic climate events, 700 years apart and more than 45 centuries ago, are teasing scientists who are now trying to use ancient records to predict future world climate.
Researchers here have used sediment from the deep ocean bottom to reconstruct a record of ancient climate that dates back more than the last half-million years.
At times in the distant past, an abrupt change in climate has been associated with a shift of seasonal monsoons to the south, a new study concludes, causing more rain to fall over the oceans than in the Earth's tropical regions, and leading to a dramatic drop in global vegetation growth.
A poll of experts finds that a dramatic climate shift such as the death of the Amazon forest or the disappearance of Greenlandâ€™s ice is more than 50 percent likely during the next 200 years under the worst case global warming scenarios.
A new study released Wednesday shows that large, sudden climate changes in the North Atlantic have a rapid impact on the South Atlantic, and also affect weather throughout the entire world.
New data, published yesterday, disproves the recent theory that a large comet exploded over North America 12,900 years ago, causing a shock wave that traveled across North America at hundreds of kilometers per hour and triggering continent-wide wildfires.
The United States could suffer the effects of abrupt climate changes within decades â€” sooner than some previously thought - says a new government report.
An abrupt release of methane, a powerful greenhouse gas, from ice sheets that extended to Earth's low latitudes some 635 million years ago caused a dramatic shift in climate.
What does global warming have to do with global peace? The globe may find out sooner than we think, experts say. "Climate change is and will be a significant threat to our national security and in a larger sense to life on Earth as we know it to be."
