My colleagues and I argue these warming trends are unlikely the result of natural climate variability alone. The effects of human-made climate change appear to have worked in tandem with the significant influence natural variability in the tropics has on Antarctica’s climate. Together they make the South Pole warming one of the strongest warming trends on Earth.
Why This Matters: Climate scientists long thought Antarctica’s interior may not be very sensitive to warming, but no major region of our planet is untouched by climate change. Antarctica’s ice sheet contains enough water to raise global sea levels by nearly 200 feet, according to the World Meteorological Organization. Thus accelerated warming in the region has serious implications for coastal communities around the world.
The Study: As CNN reported, Clem and his team analyzed weather station data at the South Pole, as well as climate models to examine the warming in the Antarctic interior.
They found that between 1989 and 2018, the South Pole had warmed by about 1.8 degrees Celsius over the past 30 years at a rate of +0.6 °C per decade — three times the global average.
The scientists said the main cause of the warming was increasing sea surface temperatures thousands of miles away in the tropics.
by Julia Fine, ODP Contributing Writer Climate change is, of course, a global phenomenon, but out of the contiguous United States, the Northeast is experiencing it particularly severely. As Kate Olson recently reported in Civil Eats, farmers in Maine are “struggl[ing]” with this “new, harsher climate reality” that includes even more deeply unpredictable weather events […]
by Julia Pyper, host and producer of Political Climate John Podesta has had a long and distinguished career in American politics. The veteran Democrat official recalls a time when Members of Congress were open to working across the political aisle, the debate was healthy and the resulting policies were less prone to repeal. But today […]
As John Schwartz reported for the New York Times, for more than 40 years, scientists have had an idea of how much greenhouse gases will warm our planet. They’ve expressed the answer as a range of possible temperature increases, between 1.5 and 4.5 degrees Celsius, that will result from carbon dioxide levels doubling from preindustrial […]
