Park Williams Discovers History and Science in a Tree Ring

Park Williams studies trees and climate, in particular the causes of drought and the effects of climate change on forests. In this latest in a series of Earth Institute videos, we spoke to him about what he does, what’s important about it, and how his interest in history and environmental science blended into a career.

The Science of Carbon Dioxide and Climate

The vast majority of scientists around the world agree that our climate is changing at a faster rate than ever recorded in human history because of our use of fuels such as coal and oil, so-called fossil fuels. The conclusion rests on basic physics known since the early 1800s, when physical scientists first recognized that carbon dioxide, then a recently discovered gas, could act as a sort of greenhouse, preventing heat introduced by the sun from escaping back into space – the “greenhouse effect.”

Save EPA

Until now, Administrator Pruitt has been an enemy of EPA, but he has a chance to change the narrative and demonstrate that his conservative principles are consistent with the goals of environmental protection. I hope he decides to save EPA and serve the American people.

Putnam studies glaciers around the world, part of an effort to understand past climate change and the potential impacts of warming today.

In High Sierras, Remnants of Ice Age Tell a Tale of Future Climate

Aaron Putnam’s research in the California Sierras is part of an effort to study glaciers around the world—in Europe’s Alps, the Himalayas, Mongolia, Patagonia, New Zealand. He’s working on an important piece of the worldwide climate puzzle that can help us understand what’s ahead in a warming world.
