Extreme Weather Map | Fact Sheet
Hitting Close to Home | Global Warming is Fueling Extreme Weather Across the U.S.
Every year, weather-related disasters injure or kill hundreds of Americans and cause billions of dollars in damage.  Many of the risks posed by extreme weather will likely increase in a warming world. Scientists have already noted increases in extreme precipitation and heat waves as global warming raises temperatures and exacerbates weather extremes. 
Weather-related disasters affect millions
- Every Montana citizen lives in a county that was affected by at least one federally declared weather disaster since 2010.
- Montana experienced six weather-related disasters including severe storms, wildfires, floods, and droughts since September 2010.
New Online Map Shows Weather-Related Disasters and Extreme Weather’s Personal Impact
Environment Montana’s new interactive extreme weather map shows weather-related disasters in the United States over the last five years and tells the stories of the people and communities who have endured some of those disasters.
Map visitors can focus in on specific types of weather and even add their own stories of how extreme weather has affected their lives.
Extreme weather causes widespread destruction
- In 2015 drought conditions persisted across numerous western states, including Montana. Hundreds of thousands of acres of farmland remained fallow and required excess groundwater for irrigation. The total estimated costs of the 2015 western drought were more than $1 billion in the region.
- For the first time on record, in 2015 wildfires in the United States burned more than 10 million acres in a single year, including areas in Montana. The wildfires caused at least 12 deaths and more than $1 billion in estimated damages in the affected region. 
Weather extremes are becoming more common
Globally, 2015 was Earth’s hottest year on record, surpassing 2014.  Many types of extreme weather are expected to become more frequent or severe in a warming world, which could lead to more weather-related disasters.
- Tropical Storms and Hurricanes: Global warming has the potential to make tropical storms more destructive. Hurricanes and other coastal storms are likely to be more powerful  and rainier,  while storm surges could be more destructive as sea levels rise. 
- Heavy Rain and Snow: Extreme precipitation is already increasing; continued trends could increase the risk of intense downpours, heavy snowstorms and severe flooding. 
- Droughts and Wildfires: While global warming is anticipated to bring more rain to some areas, it will also likely elevate temperatures and extend dry spells. The potential for stronger drought—and greater area burned by wildfires—will increase, particularly in the West and Southwest.
Montana must cut global warming pollution
To protect our children and our communities from a future of worsening extreme weather, Montana, its cities, and the nation should limit global warming pollution to levels consistent with the Paris Climate Agreement—at least 40 percent below 1990 emissions by 2030 and at least 80 percent by mid-century. Essential steps include:
- Effectively implement the Clean Power Plan. Montana should drop its legal challenge to the Clean Power Plan, the largest single step that the United States has taken to reduce dangerous carbon pollution from power plants. Moreover, the state should plan to comply with the policy using clean energy solutions, cover new and existing plants, and ensure that polluters pay.
- Maximize energy efficiency. Montana and its cities should expand energy efficiency programs and adopt net-zero energy building codes and retrofit standards.
- Shift to 100 percent clean power. Meeting our climate goals will require accelerating deployment of clean, renewable energy sources such as solar and wind power. The state should increase its clean energy standard.
- Use clean energy for transportation and heating. Montana should shift energy for transportation and heating away from fossil fuels and toward electricity or other forms of clean energy.
- Keep dirty fuels in the ground. To protect the global climate and our health, the nation must cease construction of any new fossil fuel infrastructure and leave our coal, oil and gas reserves in the ground.
