Rising temperatures due to climate change means more precipitation falls as rain rather than snow, reducing snowpack levels, and threatening water supplies for many parts of Washington. In many areas, climate change is likely to increase water demand while water supplies are shrinking.
Will Seattle be affected by global warming?
Seattle is already seeing the impacts of climate change, including record-breaking heat and smoke from West Coast wildfires; in the coming decades, parts of the city will be periodically inundated with floodwaters. … Seattle’s Space Needle obscured by smoke from wildfires in September 2020.
How will global warming affect the Pacific Northwest?
Climate change will alter Northwest forests by increasing wildfire risk, insect and disease outbreaks, and by forcing longer-term shifts in forest types and species. Many impacts will be driven by water deficits, which increase tree stress and mortality, tree vulnerability to insects, and fuel flammability.
How will rising sea levels affect Washington state?
Sea level rise will exacerbate existing risks and vulnerabilities, such as shoreline and coastal bluff erosion, storm surge, flooding and groundwater intrusion. Washington State is due for a new sea level rise assessment.
How will climate change affect the Puget Sound?

What will Seattle look like in 2050?
Central estimates indicate that Seattle will experience 10 inches of sea-level rise by 2050, and 28 inches by 2100, and 47 inches by 2150. While chronic inundation is a concern, sea-level rise impacts will first be noticed episodically with more frequent tidal flooding events.
Why is Washington state so hot right now?
Heat domes, or sprawling ridges of high pressure, are a staple of summertime. … The high-pressure system has been centered near the international border, with clockwise flow around it bringing easterly winds for much of the Columbia River Basin and, broadly, Idaho, Washington and Oregon.
How does the Pacific Ocean affect Washington’s climate?
Washington’s western boundary is formed by the Pacific Ocean. The seasonal change in the temperature of the ocean is less than the seasonal change in the temperature of the land, thus the ocean is warmer in winter and cooler in summer than the adjoining land surfaces.
What is Washington state climate?
Washington has two distinct climate zones. Mild, humid, summer days west of the Cascades rarely rise above 26°C (79°F), and winter days seldom drop below 8°C (46°F) while the east of the state has warm summers and cool winters.

Is Whidbey Island sinking?
Generally speaking, scientists believe the area around Neah Bay on the Olympic Peninsula is rising while the land in the South Sound in sinking. Whidbey Island is on kind of a pivot point, which makes it difficult to predict its vertical movement.
How high is Seattle above sea level?
The average sea level in Puget Sound is currently projected to rise about 24 inches (+/– 12 inches) by 2100, though other studies suggest it could rise much higher. While there is broad consensus about the upward trajectory of sea level, scientists are still learning how fast, or slow, change will occur.
Is Seattle prepared for climate change?
Seattle is preparing for a changing climate and the resulting economic, infrastructure, health, and other community impacts by integrating consideration of climate change into decision making and identifying mitigation and adaptation actions to enhance the resilience of services and infrastructure.
Is Seattle Getting Rainier?
Seattle has also become even wetter, if you can believe that. … That soggy decade has pushed Seattle’s new annual rainfall normal to 39.34 inches — a rise of nearly 2 inches from our previous normal of 37.49 inches.
