Record global heat in the first half of 2016 has caught climate scientists off-guard, reports Thompson Reuters Foundation.

“What concerns me most is that we didn’t anticipate these temperature jumps,” David Carlson, director of the World Meteorological Organization’s (WMO) climate research program, told Thompson Reuters Foundation late Monday. “We predicted moderate warmth for 2016, but nothing like the temperature rises we’ve seen.”

“Massive temperature hikes, but also extreme events like floodings, have become the new normal,” Carlson added. “The ice melt rates recorded in the first half of 2016, for example—we don’t usually see those until later in the year.”

Indeed, extreme weather events are currently wreaking havoc around the world.

In Southern California, firefighters are battling one of the “most extreme” fires the region has ever seen. The so-called sand fire had consumed 38,346 acres as of Wednesday morning and forced the evacuations of 10,000 homes, and one person has died.

Meteorologist Eric Holthaus reported on the unusual fire last Friday in Pacific Standard:

Time-lapse footage filmed on July 23 showed the fire’s tall flames and rapid growth:

“Since late 2011,” Holthaus explained, “Los Angeles County has missed out on about three years’ worth of rain. Simply put: Extreme weather and climate conditions have helped produce this fire’s extreme behavior.”
