It may be tempting to attribute current weather trends like the record warmth and early rains on climate change caused by humans. 

But KPLU weather expert Cliff Mass says a newly-published paper should give us pause. It shows that the global warming of approximately 1 degree Celsius on the U.S. West Coast since 1900 appears more likely to be the result of natural variations than of human inputs of greenhouse gases.

Tim Durkan

Go ahead and gloat. We’ve got one of those hot, sunny August western Washington weekends ahead that make it worth living here despite the long, dark winters.

Low clouds will melt away, says KPLU weather expert Cliff Mass, as temperatures steadily rise over the weekend, hitting 90 maybe even as early as Sunday and certainly by Monday.  

“A warming period is going to happen,” said Mass. “And that’s because a trough that brought us cooler temperatures this week is moving off and a pretty high-amplitude ridge is building in its place.”
