Heat is heading for new extremes

Heatwaves that used to arrive once every 20 years or so could become annual events by 2075 across almost two-thirds of the planet’s land surface – if humans go on burning ever more fossil fuels and releasing ever more greenhouse gases. Claudia Tebaldi, visiting scientist at the US National Center for Atmospheric Research, and Michael Wehner, senior staff scientist at […]

Antarctic Ice Sheet Mass gains greater than losses

Antarctic Ice Sheet

A new NASA study on the Antarctic Ice Sheet says that an increase in Antarctic snow accumulation that began 10,000 years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers. The research challenges the conclusions of other studies, including the Intergovernmental Panel on Climate Change’s (IPCC) 2013 report, which says that […]

The Sun Is Coming!

Earth got off relatively easy last week after being hit by the biggest blast of solar radiation since 2005—but we may not be so lucky next time. Last week’s coronal mass ejection, in which a solar flare whipped an arc of magnetic particles toward Earth at 4 million mph, led some airlines to reroute flights away from the poles, where […]

Antarctic Thaw Now Unstoppable

The continued melting of the West Antarctic ice sheet is progressing faster than expected, and the resulting rise in sea levels will have a global impact.The stark new findings point to a potential sea-level rise of up to 10 feet or more in the coming centuries. This increase in the global sea-level will threaten many major cities, including New York, […]
