Researchers identify sharp rise to about 0.35C every decade, after excluding natural fluctuations such as El Niño

Researchers identify sharp rise to about 0.35C every decade, after excluding natural fluctuations such as El Niño

Humanity is heating the planet faster than ever before, a study has found.

Climate breakdown is occurring more rapidly with the heating rate almost doubling, according to research that excludes the effect of natural factors behind the latest scorching temperatures.

It found global heating accelerated from a steady rate of less than 0.2C per decade between 1970 and 2015 to about 0.35C per decade over the past 10 years. The rate is higher than scientists have seen since they started systematically taking the Earth’s temperature in 1880.

“If the warming rate of the past 10 years continues, it would lead to a long-term exceedance of the 1.5C (2.7F) limit of the Paris agreement before 2030,” said Stefan Rahmstorf, a scientist at the Potsdam Institute for Climate Impact Research and co-author of the study.

    “An important caveat, however, is that the acceleration may prove temporary,” said Beaulieu, who has published on the topic but was not involved in the new study. She added that the strong El Niño of 1998 also produced a period of apparent anomalous warming.

    “The relative slowdown that followed was interpreted as evidence of a pause in global warming,” she said. “Continued monitoring over the next several years will be essential to determine whether the accelerated warming rate identified here represents a lasting shift or a transient feature of natural variability.”

    It might be temporary. It might be transient. Then again, it might not be. We’d be taking a huge risk by proceeding on the assumption that it will only be temporary. If we’re wrong the consequences could be severe. Maybe some people are willing to risk the future on hope, but I don’t think that’s a wise decision.

    You ever hear the saying: hope for the best, prepare for the worst? We’re not prepared. Not even close. It’s true the worst case scenario isn’t likely, but it is possible. And worse case, though not necessarily worst care scenarios are also possible, and more likely. We’re not prepared for those either.
