'Our planet is teetering on the edge of several tipping points that once
passed, will topple into a cascade of ecological changes.
Extreme heatwaves, droughts, floods, and storms are becoming more common and
intense; the energy trapped by Earth's atmosphere and oceans fizzing up like a
carbonated soft drink under pressure.
Now a new study simulating Earth's future out to 2100 shows just how
fundamentally incremental changes in temperature and precipitation could alter
climes on a local level, so much so that we would have to redraw maps first
conceived in the 1880s.
"By the end of the century, 38 percent to 40 percent of the global land area is
projected to be in a different climate zone than today," writes the team of
researchers, led by senior author Paul Dirmeyer, a climate scientist at George
Mason University in Virginia.
Depending on which climate models the researchers used to generate projections
of future global change, those estimates could rise even further, such that
close to 50 percent of Earth's land area could be thrust into an unfamiliar
climate zone. The shifts became more pronounced with the latest generation of
climate models, which are more sensitive to changes in climate and predict
steeper rates of global warming.'
