The National Climate Assessment was released this week, which summarizes climate change's impacts on the United States, now and in the future. Produced by a team of more than 300 experts and guided by a 60-member Federal Advisory Committee, the study was also extensively reviewed by the public, federal agencies and a panel of the National Academy of Sciences.
The report finds that if greenhouse gas emissions continue to increase, global warming could exceed 10 degrees by the end of the century. A quote from the study's overview says, "This National Climate Assessment concludes that the evidence of human-induced climate change continues to strengthen and that impacts are increasing across the country."
This scientific report is mandated by Congress and is the pinnacle of years of work by hundreds of the nation's leading climate experts. They reviewed the scientific literature and summarized how climate change is affecting our country. The two main conclusions are:
The planet's climate is changing; it is apparent across the U.S. and the last 50 years' worth is chiefly due to human activities, particularly the burning of fossil fuels.
Extreme weather is on the rise in recent decades and new, stronger evidence confirms that some of these increases are human-caused.
Our homes, food, water and the very air we breathe are being affected.
Global warming is more than something that our children and future generations will face. It is our reality now. Climate change is already affecting our country and economy. Now that the situation is hitting home, perhaps we will start to make the changes we must make to reduce our carbon footprints and fund clean energy projects.
