Scientists have rejected a government climate report released last year which claimed 15-year "hiatus" in global warming, stressing that it never actually existed.
A group of scientists - including Michael Mann of "hockey stick" curve fame - has released a new report debunking a controversial National Oceanic and Atmospheric Administration (NOAA) report from last year. The scientists said that global warming has accelerated faster than surface temperature readings have shown.
"Overall, there is compelling evidence that there has been a temporary slowdown in observed global surface warming," Ed Hawkins, a climate scientist at the University of Reading and co-author of the paper, wrote in a blog post on the new research.
Hawkins noted that "the most recent observed 15-year trends are all positive, but lower than most previous similar trends in the past few decades which is a clear demonstration that the rate of change has slowed since its peak."
A Stanford University study published last year in September has denied any chance of global warming hiatus. The study team added, "An apparent lull in the recent rate of global warming that has been widely accepted as fact is actually an artifact arising from faulty statistical methods." "Our results clearly show that, in terms of the statistics of the long-term global temperature data, there never was a hiatus, a pause or a slowdown in global warming," said Noah Diffenbaugh, a climate scientist in the School of Earth, Energy & Environmental Sciences, and a co-author of the Stanford University study.
