Beyond the Arctic, Climate Change in Oregon
As the climate changes, the Arctic is melting twice as fast as the rest of the world. But that doesn't mean that the rest of the country is escaping the effects of climate disruption. In fact, climate disruption can be felt far beyond the Arctic. To highlight the impacts of climate change both in the melting Arctic and across the country, this week exiled (costumed) polar bears will be visiting other communities that are also feeling the heat. You can follow the tour online here. Read on for a glimpse at what climate disruption could mean for people in Oregon.
Climate change is gradually unveiling itself throughout the Pacific Northwest in a variety of ways, including alterations in precipitation and temperature that will ultimately affect numerous industries in the state of Oregon. More specifically, agriculture, skiing, forestry, and salmon will all be impacted by Oregon’s changing climate. Salmon are often identified as an iconic species for the Pacific Northwest, as well as a keystone species in many ecosystems, thus their endangerment as a result of warming temperatures is an extremely significant issue. Warmer temperatures in Oregon will result in more rain precipitation and less snowfall, which will cause overall smaller annual snow-packs and consequently altered stream-flow times. An increase in precipitation could potentially cause frequent floods, therefore increasing mortality rates among salmon eggs due to gravel aggravation. The salmon lifecycle may also be affected as a result of snowpack melting earlier in the spring, hence disrupting the normal migration patterns for sea-bound fish. Additionally, warmer river temperatures bring an influx of problems for developing salmon, such as providing ideal habitat for other fish species that pose as competitors or predators of salmon, thus lowering their survival rates. Warm water temperatures may also provide insufficient nutrients and resources for developing salmon. Evidently, salmon will be negatively affected by climate change in countless ways, thus the management and restoration of salmon habitat has the utmost importance when dealing with global warming in the Pacific Northwest.
While salmon will undoubtedly be negatively impacted by warming temperatures, there are other consequences of climate change in Oregon that also hold significance, such as agriculture. More frequent droughts could reduce water supply needed for sufficient irrigation, growing seasons could be altered, and an invasion of pests may arrive due to warmer temperatures. All of these concerns may jeopardize the stability of Oregon’s agriculture industry. Health distresses may also become significant if Oregon begins to see increased smog as a result of higher temperatures. Pollen seasons could be longer as well, posing additional threats to people with allergies or asthma. Economically, many industries in Oregon will most likely be affected because of a disruption in BPA hydroelectric power, due to a lower water supply in the summer months. Moreover, the skiing industry could disappear altogether if winter snowpack is dramatically reduced. Frequent droughts in the summertime will bring recurrent and heightened wildfires, so the timber industry could likewise be adversely affected. Clearly, Oregon is already seeing the effects of a changing climate, but many unforeseen consequences are possible in the near future, which is why Oregonians need to use mitigation and management to alleviate these impending costs.-- Annie Weaver, Sierra Club, Oregon
