Evidence disproving tropical ‘thermostat’ theory:global warming can breach limits for life
disproving tropical thermostat theory global warming breach limits for life
2017/3/14
New research findings show that as the world warmed millions of years ago, conditions in the tropics may have made it so hot some organisms couldn’t survive.Longstanding theories dating to the 1980s s...
Long time-series of chemical and isotopic compositions of Vesuvius fumaroles: evidence for deep and shallow processes
