Nasa: Antarctic ice-shelf will be gone by 2020

According to a new study by Nasa, Antarctica’s Larsen B ice-shelf is on course to completely disintegrate within the next five years. Studies show that the 10,000-year-old ice shelf, after partially collapsing in 2002, is “quickly weakening.” “These are warning signs that the remnant is disintegrating,” said Ala Khazendar of Nasa’s Jet Propulsion Laboratory (JPL) in Pasadena, California. “Although it’s […]

Drastic climate change

An analysis of isotopes in marine fossils from around the world yielded the most complete record of Earth’s temperatures yet—and showed that the planet is heating up at a rate unprecedented in the past 11,300 years. Scientists say that if it weren’t for greenhouse gas emissions, a cooling trend that began 5,000 years ago after a shift in the planet’s […]
