A new study examining explanations for the 10- to 15-year “hiatus” in global warming has scientists “more confident than ever that human influence is dominant in long-term warming.”

“In a time coinciding with high-level political negotiations on preventing climate change, skeptical media and politicians were using the apparent lack of warming to downplay the importance of climate change,” researchers with the Institute for Atmospheric and Climate Science (IACS) in Switzerland wrote in a study published Thursday in the journal Nature.

“A few years of additional data are unlikely to overturn the vast body of evidence that supports anthropogenic climate change,” reads the study, adding the recent El Nino and new data have them “more confident than ever that human influence is dominant” in global warming.

IACS’s study looked at different explanations for the “hiatus” in global warming, which the study defined as the 10 or 15 years after 1998, ultimately to put to rest arguments by skeptics the lack of warming during this time cut into theories of catastrophic warming.

“I think it does a really good job at tying a bow on the last five years or so of hiatus arguments,” Penn State University climate scientist Michael Mann told The Los Angeles Times.

But skeptics are already firing back at IACS’s work.
