In a world of worsening climate extremes, a single red line has caught many people's attention.
The line, which charts sea surface temperatures in the North Atlantic Ocean, went viral over the weekend for its startling display of unprecedented warming — nearly 2 degrees (1.09 Celsius) above the mean dating back to 1982, the earliest year with comparable data.
Ocean temperatures are so anomalously high that Eliot Jacobson, a retired mathematics professor who created the graph using data from the National Oceanic and Atmospheric Administration, had to "increase the upper bound on the y-axis," he said.
