Washington D.C. — For the second year in a row, scientists behind a major annual climate report say they have spotted weather crises that would not have occurred if not for global warming caused by human-made climate change.

In the “Explaining Extreme Events from a Climate Perspective” report — the latest and seventh edition of which was published Monday — 120 climate scientists from 10 countries detailed the extreme weather events from 2017 and what role if any climate change played in the disasters.

The report, which is actually a collection of peer-reviewed essays from the Bulletin of the American Meteorological Society, covers incidents in every continent around the world. In many cases, they say there are links between the world’s worth weather and its ever-evolving climate. For example, without human-backed warming of the Pacific Ocean, Tanzania, Ethiopia, Kenya and Somalia would not have witnessed an extensive drought and subsequent famine last year.

“The consequences in nature are unfolding in front of our eyes,” Martin Hoerling, a NOAA research meteorologist said at Monday’s unveiling of the report at the American Geophysical Union conference in Washington, D.C. He said that in 1990, the first Intergovernmental Panel on Climate Change predicted that the world would experience exactly these types of weather events in 30 years.

Here’s a quick rundown of how some of these events unfolded in the U.S. in 2017.

Drought, The Great Plains and the Camp Fire

California may have an unwelcome reputation as a tinderbox, based on 2018’s run of huge wildfires. But last year provided some forewarning for what has happened recently across other parts of the American West, Hoerling said.

Starting in May 2017, the Northern Great Plains — namely South Dakota, North Dakota, and Montana — were swept by a four-month-long drought. Monday’s report found that climate change made this drought 50 percent more likely to happen, largely because of a drop in relative humidity. It was so dry that the region recorded its fifth lowest levels of soil moisture in nearly 40 years. At the same time, more than half of this region also experienced records lows in rainfall.
