This website describes what kind of research NCAR is doing and what they have been finding on the issue of climate change. It goes into detail about what the climate was like in the past, the climate in the future, and what the causes of climate change really is. The climate has been changing ever since the Earth began, even before humans, but modern weather measurements only go back to 100-150 years ago. We don't know what the climate of the Earth really was in the prehistoric times. The Earth is getting warmer. According to tests, the Earth's surface temperature has risen more than 1.33 degrees fahrenheit since the late 1800s. There is more about what is causing the climate to change and what the climate will look like in the future.
