Federal scientists: US already feeling effects of climate change
The EPA and the administration might not be fans of climate science, but government scientists from 13 federal agencies have concluded that Americans are feeling the effects of climate change right now. According to the draft report obtained by The New York Times, the average temperature in the country has risen dramatically since the 1980s. Also, it emphasizes how “many lines of evidence demonstrate that human activities, especially emissions of greenhouse (heat-trapping) gases, are primarily responsible for recent observed climate change.”
The scientists linked rising temperatures in the Western and Northern US to man-made climate change, though they can’t find a direct link in the Southeast. They noted how the number and severity of cool nights have decreased since the 1960s and how warm days and heat waves have become more common. The wetter parts of the country are getting more rainfall, while the drier parts are becoming even drier.
They also name human activity as the primary culprit for the rising temperatures in Alaska and the Arctic. Temperatures in those locations are increasing twice as fast as the global average, leading the scientists to warn that the “accelerated rate of Arctic warming will have a significant consequence for the United States…” After all, at the rate land and sea ice is melting in the Arctic, sea levels are bound to rise and threaten America’s coastal communities.
The scientists’ conclusion directly contradicts the administration’s earlier claims that our contribution to climate change is uncertain. That’s why scientists around the country will be following the draft closely — the EPA and the White House will have to approve it before it’s officially released.
The team also said that to be able to prevent global mean temperature from increasing more than 2 degrees Celsius by the end of this century, we need to significantly reduce global carbon dioxide levels. To make that possible, nations all over the globe will have to follow the guidelines set by the Paris climate accord. Unfortunately, the United States, one of the biggest carbon dioxide emitters in the world, walked away from the agreement in June.
