Chart of global temperature since 1950 showing the phase of the El Niño-La Niña cycle. Via NASA. A new study finds that when climate models factor in the temporary warming and cooling impact of El Niño and La Niña, they accurately predict recent global warming. And that is consistent with recent studies that led one climatologist to say, “Global temperatures look set to rise rapidly.” GLOBAL WARMING CONTINUES TO ACCELERATE A study last year found that global warming has accelerated in the past 15 years, especially in the ocean.
