Latest Abrupt climate change Stories
Scientists have long been concerned that global warming may push Earth's climate system across a "tipping point," where rapid melting of ice and further warming may become irreversible -- a hotly debated scenario with an unclear picture of what this point of no return may look like.
The role of the hydrological cycle during abrupt temperature changes is of prime importance for the actual impact of climate change on the continents.
The National Research Council says that even gradual climate change can have abrupt impacts in human infrastructure and ecosystems if critical thresholds are crossed, so an early warning system needs to be developed.
Food shortages, natural disasters, energy supply issues and the spread of epidemics are some of the possible climate-related perils the U.S. military needs to prepare to deal with.
Ice samples that profile Greenland glaciers have long been used to give climate scientists historical temperature data, but those samples could be misleading.
An international team of scientists, led by Dr Stephen Barker of Cardiff University, has produced a prediction of what climate records from Greenland might look like over the last 800,000 years.
There have been instances in Earth history when average temperatures have changed rapidly, as much as 10 degrees Celsius (18 degrees Fahrenheit) over a few decades, and some have speculated the same could happen again as the atmosphere becomes overloaded with carbon dioxide.
International team of climate researchers drill through a mile and half of the Greenland ice sheet in search of climate change insights.
North Pacific circulation radically changed by past post-glacial warming.
An international team of scientists, led by Denmark, says it set a single-season deep ice core drilling record this summer in Greenland. The researchers, with the University of Colorado at Boulder as the lead U.S.
