Climate change

Whereas weather is the daily to seasonal changes in patterns of temperature, precipitation, humidity, and wind; climate change is the long-term trend of these patterns. Some short-term climate variation is normal from cycles of the Pacific Decadal Oscillation and El Niño-Southern Oscillation; however, natural causes and natural variability alone cannot explain the rapid increase in global temperatures in the last 50 years. A chief cause, say scientists, is the rise in global greenhouse gases due to human activity. This range of natural and human factors driving the warming or cooling influences on global climate plays an essential role in shaping ecosystems, including Puget Sound.

Overview

A 2015 report from the University of Washington provides the most comprehensive assessment to date of the expected impacts of climate change on the Puget Sound region.

We have published a yearly round-up of stories from our magazine Salish Sea Currents. The 2020 edition focuses on the impact of climate change on the Salish Sea and includes a special section on the effect of global warming on infectious diseases in the ecosystem. 

Few environment problems in the Salish Sea have been studied more than the steep decline in salmon populations. But one potential contributor to these declines has gained less attention. Scientists say infectious disease may play a wider role than previously understood.

Years after the appearance of the devastating marine heat wave known as "the blob," scientists are still working to understand how it has affected the Salish Sea. In some ways, they say, it is like the blob never left.

The revival of an Indigenous aquaculture practice has come to the southern Salish Sea. Clam gardens could help First Nations in British Columbia and Washington state address issues of climate change and food sustainability. 

Identifying kelp stocks that are tolerant of warmer waters could help the Salish Sea’s iconic underwater forests survive climate change.

Historically, the eastern part of the state has seen the largest impacts from fires, but climate change is now increasing the risk west of the Cascades. That could have big implications for many rural communities throughout Western Washington, including those in the Puget Sound region.
