Act for Our Future

The Northwest includes Oregon, Washington, Idaho and Western Montana. According to the U.S. Global Change Research Program report, Global Climate Change Impacts in the United States (2009): 

“Annual average temperature over the Northwest region as a whole rose about 1.5°F over the past century, with some areas experiencing increases up to 4°F. The region’s average temperature is projected to rise another 3 to 10°F in this century, with higher emissions scenarios resulting in warming in the upper end of this range. Increases in winter precipitation and decreases in summer precipitation are projected by many climate models, though these projections are less certain than those for temperature. Impacts related to changes in snowpack, streamflows, sea level, forests, and other important aspects of life in the Northwest are already underway, with more severe impacts expected over the coming decades in response to continued and more rapid warming.”

The report identifies several key issues for the Northwest as climate rapidly changes:

• “Declining springtime snowpack leads to reduced summer streamflows, straining water supplies.”
• Increased insect outbreaks, wildfires, and changing species composition in forests will pose challenges for ecosystems and the forest products industry.”
• "Salmon and other coldwater species will experience additional stresses as a result of rising water temperatures and declining summer streamflows.”
• “Sea-level rise along vulnerable coastlines will result in increased erosion and the loss of land.”

Montana is changing 

From its mountain glaciers and hot springs to its deep tradition of ranchers and land stewardship, Montana’s beauty is bountiful. People from all over the U.S. come to Montana to enjoy its pristine trout streams, extensive vistas, and numerous outdoor activities.

Montana is home to some of America’s most treasured natural environments and magnificent wildlife—grizzlies, wolves and bison to name a few.

Unfortunately, Montana’s unique natural landscapes are at risk from climate change. The fourfold increase in major wildfires in the Western U.S. over the last two decades has been felt by Montanans. Forests will be further damaged by combinations of drought stress and insect infestations.

Predicted higher temperatures and drier weather will lower streamflows and raise water temperatures, harming trout and other fish. Natural treasures are not the only aspect of Montana being threatened; the land which Montanans depend on for ranching and farming will also be impacted by climate change.

Drought and weather variations will lead to decreased forage quality and may force farmers to change crop types. To address climate change, the U.S. must prepare for its impacts and sharply reduce greenhouse gas emissions.
