How is climate change affecting the Pacific Northwest?

Why is Seattle getting so hot?

Why is it so hot? The region is experiencing what is called a heat dome. A giant zone of high pressure over the region is compressing the air and generating heat underneath it. In addition, the winds are coming from the East, bringing in inland heat.

Why is Northwest so hot?

The oppressive heat that settled in the Pacific Northwest was the result of a wide and deep mass of high-pressure air that, because of a wavy jet stream, parked itself over much of the region. Known as a heat dome, such an enormous high-pressure zone acts like a lid, trapping heat so it accumulates.

How will climate change affect Alaska?

Average annual temperatures have increased by 3 degrees Fahrenheit and average winter temperatures by 6 degrees Fahrenheit. Alaskans are already seeing earlier spring snowmelt, widespread glacier retreat, drier landscapes, and more insect outbreaks and wildfires because of climate change.

How is climate change affecting Puget Sound?

The Puget Sound watershed — the area west of the Cascades Mountains that stretches from the state capitol up to the Canadian border — is warming. It also faces rising seas, heavier downpours, larger and more frequent floods, more sediment in its rivers, less snow, and hotter, drier summer streams.

What is Washington state climate?
