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.”

The summer season over the Greenland ice sheet is characterized by surface melting, creating a texture of patterns with supraglacial lakes and streams, crevasses and canyons. Over the past decades, melting has been increasing in Greenland, hence increasing its contribution to sea level rise. In this project, we specifically study how meltwater drains and how albedo (e.g., how ‘bright’ the surface is) modulates melting.

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.
