The Last Time There Was This Much CO2, Trees Grew at the South Pole
“The glaciers shrinking fastest are in central Europe, the Caucasus region, western Canada, the U.S. Lower 48 states, New Zealand and near the tropics,” lead author Michael Zemp, director of the World Glacier Monitoring Service at the University of Zurich told Time Magazine. Glaciers in those places are losing an average of more than 1 percent of their mass each year, according to the study. “In these regions, at the current glacier loss rate, the glaciers will not survive the century,” added Zemp.
Another recent report showed that the last time there was this much CO2 in the atmosphere (412 ppm), in the Pliocene Epoch 5.3 to 2.6 million years ago, sea levels were 20 meters higher than they are right now, trees were growing at the South Pole, and average global temperatures were 3 to 4 degrees Centigrade (3°-4° C) warmer, and even 10°C warmer in some areas. NASA echoed the report’s findings.
And if business as usual continues, emissions will only accelerate. The International Energy Agency announced that global carbon emissions set a record in 2018, rising 1.7 percent to a record 33.1 billion tons.
