STUDY: Global Warming ‘Slowdown’ Could Last Another 15 Years

earth-sunWith 2016 on track to being the warmest year on record, some climate scientists and environmentalists declared the recent slowdown in global warming to be over.

But that might not be the case, according to a new study by National Oceanic and Atmospheric Administration (NOAA) scientists. They say there’s a 16 percent chance global warming could progress at a slower rate through 2020, and a 6 percent chance the slowdown could last until 2030.

“The spike in global temperatures from the 2015/2016 El Nino has caused some to declare the warming slowdown to be over,” Dr. Judith Curry, a Georgia Tech climate scientist who was not involved in the study, wrote in her blog.

“This is not necessarily the case; we will need at least another 5 years of observations to determine whether the slowdown is over and warming resumes at a pace of at least 0.2¬∞C/decade, or whether the slowdown will continue for another decade or two,” she wrote.

Scientists have been struggling to explain why global temperature rise slowed down in the years after 1998, a period called the “slowdown” or “hiatus” in warming. It not only surprised scientists, but forced them to question the climate models used to predict future warming.

The climate warmed at about half the rate predicted by climate models since 2000, according to the NOAA study, which sought to answer the question of why the models were so far off. In the process, they suggest there’s a chance of no warming or even slight cooling in the future.

    Ozone levels in the stratosphere stabilized after the full implementation of the Montreal Protocol in 1996. Both tropospheric and stratospheric temperatures subsequently started to level out as well.
