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.

Climate change is the biggest threat facing the world, and yesterday’s United Nations Security Council meeting was focused on the topic. United States climate envoy John Kerry, who participated in the virtual meeting, warned that ignoring the crisis and its threats to global security would mean “marching forward to what is almost tantamount to a mutual suicide pact.”
Why this Matters: Global food security, poverty rates, and public health are all negatively impacted by climate change. These destabilizing forces are already driving people to migrate and shifting power balances on the international stage.
