'There is unequivocal evidence that Earth's lower atmosphere, ocean, and land surface are warming; sea level is rising; and snow cover, mountain glaciers, and Arctic sea ice are shrinking. The dominant cause of the warming since the 1950s is human activities. This scientific finding is based on a large and persuasive body of research.'

The AMS is currently supporting a campaign to educate the public and the media on the subject of climate change. A recent survey of weather forecasters in the US showed a distinct lack of understanding of climate change and more than a 50% denial rate of climate change. The AMS is citing this lack of understanding and belief in scientific research as the reason why public opinion and US policy continues to turn a blind eye to impacts human activity is having when it comes to climate change.
