Climate Change

Climate change and global warming pollution harm Maine people, wildlife, and our environment. Global warming, also known as climate change, is caused by a blanket of pollution that traps heat around the earth. This pollution comes from cars, factories, homes, and power plants that burn fossil fuels such as oil, coal, natural gas, and gasoline.

Climate-changing pollution knows no boundaries. It enters the atmosphere, spreads across the globe, and traps heat around the earth for 50-200 years after it is emitted. That is why we need to reduce global warming pollution now, because our children, and their children, will still feel the effects of global warming for years to come. Currently, the levels of carbon dioxide in the atmosphere are at their highest levels in hundreds of thousands of years.

Learn how you can reduce climate-changing pollution and advocate for a cleaner, healthier Maine.
