Our world is losing ice at a record rate
The rate at which ice is disappearing across the planet has been speeding up, with 65% since the 1990s, a survey of global ice loss using European Space Agency satellite data reveals. Source: https://earthsky.org/earth/esa-satellites-show-record-rate-ice-loss…
Earth is Losing Ice Faster Today Than in the Mid-1990s, Study Suggests
Earth’s ice is melting faster today than in the mid-1990s, new research suggests, as climate change nudges global temperatures ever higher. From a report: Altogether, an estimated 28 trillion metric tons of ice have melted away from the world’s sea ice, ice sheets and glaciers since the mid-1990s. Annually, the melt rate is now about 57 percent faster than it was…
2020 Was Second-Hottest Year On Record, NOAA Says
An anonymous reader quotes a report from NBC News: Data released Thursday by the National Oceanic and Atmospheric Administration, or NOAA, showed that 2020 now ranks as the second-hottest year, with average temperatures hitting 58.77 degrees Fahrenheit — a mere 0.04 degrees cooler than 2016, which holds the record. The Northern Hemisphere experienced its hottest year on record, surpassing the 20th…
