The latest weekly Drought Monitor update set another grim record. The brutal U.S. drought expanded to 65.45% of the contiguous U.S. — the highest ever in the Monitor’s 12-year history. The previous record was 64.8% — set just last week.

In the third quarter alone, crop production dropped $12 billion “due to this summer’s severe heat and drought.” The drop in farm inventories was so sharp in the last quarter that it wiped 0.2% off of U.S. GDP in the latest revision.

In Texas, the drought has killed more than 300 million trees. Nearly 98% of Nebraska is in extreme to exceptional drought — 3 months ago, none of it was!

The United States will suffer a series of severe droughts in the next two decades, according to a new study published in the journal Nature Climate Change. Moreover, global warming will play an increasingly important role in their abundance and severity, claims Aiguo Dai, the study’s author.

His findings bolster conclusions from climate models used by researchers around the globe that have predicted severe and widespread droughts in coming decades over many land areas…

“We can now be more confident that the models are correct,” Dai said, “but unfortunately, their predictions are dire.”
