The average warming rate in the Pacific Northwest during the next ~50 yr is expected to be in the range 0.1-0.6°C (0.2-1.0°F) per decade, with a best estimate of 0.3°C (0.5°F) per decade. For comparison, observed warming in the second half of the 20th century was approximately 0.2°C per decade.
How much warmer is the Pacific Northwest expected to get in 2050?
Regardless of the scenario, warming is projected to continue throughout the 21st century in the Pacific Northwest. For the 2050s (2041 to 2070) relative to 1950-1999, temperature is projected to rise +5.8°F (range: +3.1 to +8.5°F) for a high greenhouse gas scenario (RCP8.
What will climate change do to Washington state?
Early effects of a warming Earth have reached Washington state, as we can see from actual measurements. Annual snowpack is declining in the mountains; ancient glaciers are shrinking; sea levels are rising; and coastal waters are becoming less hospitable to sea life.
What do Pacific Northwest climate models predict for annual average precipitation in the future?
Projected Climate Change
Change in annual average precipitation in the Northwest is projected to be within a range of an 11% decrease to a 12% increase for 2030 to 2059 and a 10% decrease to an 18% increase for 2070 to 2099 for the B1, A1B, and A2 scenarios (Ch. … 2: Our Changing Climate).
What is the predicted effect of climate change on the Northwest region of the United States?
Higher temperatures, changing streamflows, and an increase in pests, disease, and wildfire will threaten forests, agriculture, and salmon populations. Sea level rise is projected to increase erosion of coastlines, escalating infrastructure and ecosystem risks.
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.
Is the Pacific Northwest getting warmer?
The Pacific north-west has heated up by an average of 2F (1.1C) over the past century, with growing wildfires, failing coastal fisheries, receding snowpack and increasing heat taking its toll upon a region historically unprepared for such extremes.
How will climate change affect Western Washington?
The changing climate will affect Washington’s agricultural sector, particularly fruits and vegetables, which often require irrigation. Because streams rather than ground water provide most of Washington’s irrigation water, the expected decline in streamflow would reduce the water available for irrigation.

Why is Washington State getting so hot?
The heat is all due to high pressure over Washington state and most of western Canada. There is also have an offshore flow (north and northeasterly winds) at the surface sending hot dry air towards our state from the high desert areas of British Columbia.
What is the climate of the Northwest?
Most of the Pacific Northwest has a cool, wet climate, which has led to the growth of thick forests. … Believe it or not, there are coastal, or temperate, rainforests in the Pacific Northwest, while the inland areas are more dry and warm. The rainforests in this area are some of the rainiest places in the world.
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.
Why does the northwest coast of North America have high rainfall?
The terrain in the PNW is the next key to the puzzle. Moist wind blowing in from the coast hits the Cascade Range, forcing the moisture higher and turning it into thick clouds and dense rainfall further inland. These mountain ranges have elevations that exceed upwards of 10,000 feet.
What is the climate of the northeast region?
Collectively, the states of the northeast are moderately rainy, and in the winter the region experiences heavy snow and freezing rain. The annual precipitation average, which includes both rain and snowfall, is approximately 46 inches a year.
What is the climate in the West Region?
The climate of the West is semi-arid, yet parts of the region get high amounts of rain or snow. Other parts are true desert which receive less than 5 inches (130 mm) of rain per year. The climate is unstable, as areas that are normally wet can be very dry for years and vice versa.
What is the Pacific Northwest environment?
In general, the Pacific Northwest has a wet and cool climate which has led to the growth of extensive forests featuring some of the largest trees in the world. The region’s coastal forests are considered temperate rainforests. More inland, however, the climate can be drier with more harsh winters and warmer summers.
