jesus...40% in 2 days? that does not bode well....
A new study, published this week in the journal Nature Climate Change, supports predictions that the Arctic could be free of sea ice by 2035.
Earth's magnetic field acts like a protective shield around the planet, repelling and trapping charged particles from the Sun. But over South America and the southern Atlantic Ocean, an unusually weak spot in the field -- called the South Atlantic Anomaly, or SAA -- allows these particles to dip closer to the surface than normal.
In a first-ever study using ozone data collected by commercial aircraft, researchers from the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder found that levels of the pollutant in the lowest part of Earth's atmosphere have increased across the Northern Hemisphere over the past 20 years. That's even as tighter controls on emissions of ozone precursors have lowered ground-level ozone in some places, including North America and Europe.
Greenland lost a record amount of ice during an extra warm 2019, with the melt massive enough to cover California in more than four feet (1.25 meters) of water, a new study said.
After two years when summer ice melt had been minimal, last summer shattered all records with 586 billion tons (532 billion metric tons) of ice melting, according to satellite measurements reported in a study Thursday. That’s more than 140 trillion gallons (532 trillion liters) of water.
This massive fire is one of thousands of blazes sweeping the Brazilian Pantanal - the world's largest wetland - this year in what climate scientists fear could become a new normal, echoing the rise in climate-driven fires from California to Australia.
An enormous chunk of Greenland's ice cap has broken off in the far northeastern Arctic, a development that scientists say is evidence of rapid climate change.
The glacier section that broke off is 110 square kilometers (42.3 square miles).
The Arctic is one place that’s been hit particularly hard by climate change. Now a new study has shown that the Arctic is beginning to transition into an entirely new climate state, leaving its predominantly frozen state behind.
An international effort that brought together more than 60 ice, ocean and atmosphere scientists from three dozen international institutions has generated new estimates of how much of an impact Earth’s melting ice sheets could have on global sea levels by 2100. If greenhouse gas emissions continue apace, Greenland and Antarctica’s ice sheets could together contribute more than 15 inches (38 centimeters) of global sea level rise – and that’s beyond the amount that has already been set in motion by Earth’s warming climate.
