Even if 2021's worldwide average temperature failed to surpass previous years' records, last year's climate events were nonetheless "a stark reminder of the need to change our ways, take decisive and effective steps toward a sustainable society and work toward reducing net carbon emissions," Carlo Buontempo, director of Copernicus, told the Times.
La Niña conditions, "a recurring climate pattern characterized by lower surface temperatures in the Pacific Ocean," assisted in lowering the mean temperature early in the year, though its effects were later offset by higher temperatures in many countries (though not all) between June and October, writes the Times, per Copernicus.
"When we think about climate change, it's not just a single progression, year after year after year being the warmest," said scientist Robert Rohde of Berkeley Earth. "The preponderance of evidence — which comes from looking at ocean temperatures, land temperatures, upper atmospheric temperatures, glaciers melting, sea ice changes — are telling us a coherent story about changes in the earth system which points to warming overall."
"Slight variations up or down, a year or two at a time, don't change that picture," he added. Read more at The New York Times.
