Researchers dial in to ‘thermostat’ in Earth’s upper atmosphere
A team has found the mechanism behind the sudden onset of a ‘natural thermostat’ in Earth’s upper atmosphere that dramatically cools the air after it has been heated by violent solar activity. Geology News — ScienceDaily
The ancient atmosphere and carbon and nitrogen in Earth’s crust
Carbon and nitrogen are central to life on Earth – life cannot exist without them, but an overabundance in the atmosphere imperils the life we have. So how much carbon and nitrogen is there on planet Earth? And how much … Continue reading
Megadrought risks in southwest U.S. soar as atmosphere warms
As a consequence of a warming Earth, the risk of a megadrought — one that lasts more than 35 years — in the American Southwest likely will rise from a low chance over the past thousand years to a 20- … Continue reading
