Pumping seawater onto the Antarctic landmass to form ice and stop sea levels rising stands little chance of success, scientists say.
If Arctic soils melt and release frozen carbon, the impact would cost almost half the world’s annual gross domestic product, researchers say.
Scientists warn that burning up the planet’s remaining fossil fuel would cause all Antarctic ice to melt and produce devastating sea level rise.
Scientists report that the great oceanic “lung” is again breathing in vast amounts of carbon dioxide from the atmosphere, but can’t say why or whether it will last.
Global temperatures have risen by 1 degree Celsius (nearly 34 degrees Fahrenheit) in the past 150 years, and one scientist says a doubling of that could unleash catastrophic sea-level rise this century.
A changing climate, rather than natural causes, is the main reason for Alaska’s glacier loss, which is set to speed up, U.S. scientists say.
The southern continent’s mysteries start to unfold as scientists use satellite data to measure the extent and pattern of ice loss that threatens to be a “runaway problem."
A panel of international climate scientists says the world has only until 2050 to bring carbon emissions to zero -- and the rewards for doing so would be immense.
Natural variability may at the moment be affecting Antarctica’s temperature more than human activity is, but climate change will still be a major influence.
Not cutting emissions of greenhouse gases could mean driving the planet across systemic boundaries from which there would be no return. Not cutting emissions of greenhouse gases could mean driving the planet across systemic boundaries from which there would be no return.
