This Map Shows Where Warming Has Accelerated Some parts of the globe are not just heating up, but heating up faster than they were just a few decades ago. A new analysis reveals where warming has gained pace.It found that, starting in the 1980s, warming began to accelerate in a few regions, first in the eastern Mediterranean and North Pacific, and later in New Zealand, southeast China, Bolivia, and the Gulf of Mexico.In some places, scientists speculate that efforts to slash pollution have caused warming to speed up.
