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.

Renewable Energy With or Without Climate Change

While renewable energy will go a long way to addressing the climate change issue, its development does not require a concern for climate change. The argument for renewable energy is that it is the logical next phase of technological development.

Indonesian Corals Shed Light on Climate System

A new coral salinity record shows that the location of the most significant hydroclimatic feature in the Southern Hemisphere, the South Pacific Convergence Zone, influences a major Pacific Ocean current.

Shifting Monsoon Altered Early Cultures in China, Study Says

The annual summer monsoon that drops rain onto East Asia has shifted dramatically, at times moving northward by as much as 400 km and doubling rainfall in that northern reach. The monsoon’s changes over the past 10,000 years likely altered the course of early human cultures in China, say the authors of a new study.

The Importance of Regulating Lead in Drinking Water

Many schools are being tested for lead in their water. But what about the libraries, hospitals, offices and old apartment buildings? As I observe the new president and his EPA designee, I worry about the adverse effect deregulating environmental protection would have on our families. There is more work to do if we are to truly understand the impact of human technology on the environment and public health.

Chris and Dan discussing notes on locations to visit based on recent satellite images and entering them into the GPS.

Sampling on the Ganges and Brahmaputra Rivers

The final phase of our revolves around visiting chars, sandy river islands, on the Ganges and Brahmaputra River. Chris and Dan are making measurements of soil salinity and moisture and spectra of the soil reflectance, while Liz and I collected samples for OSL dating and understanding the OSL properties of the river sediments here. This entails a mixture of driving around the country and spending time on small country boats and walking around the chars.

Project Aims to Map World’s Oceans by 2030

More than 85 percent of the ocean floor remains unmapped, leaving us in the dark about much of the earth’s topography. A global, non-profit effort will try to remedy that, and influence everything from climate research and weather prediction to mineral resource exploration and fisheries.

Scientists Say They Now Know Why Antarctic Meltwater Stays Below Ocean Surface

Up to now, it has been a mystery why much of the fresh water resulting from the melting of Antarctic ice shelves ends up in the depths instead of floating above saltier, denser ocean waters. Scientists working along one major ice shelf believe they have found the answer.
