Paleoclimatologist studies sea levels in a desert

Exactly how much did the sea level rise three million years ago? Okay. Probably not a question you’ve asked yourself lately. But the question and, more importantly, its answer are significant. They will help scientists understand how fast and how high our current sea levels are likely to rise as today’s global warming trend melts the remaining ice sheets in Greenland and Antarctica. Fortunately, there are researchers wrestling with the problem. Chief among them is Maureen Raymo, a paleoclimatologist at Boston University. Raymo heads a multidisciplinary team that is spending its second summer digging for evidence in the desert of …

The man behind the climate models

Warren Washington literally wrote the book on climate modeling. Introduction to Three-Dimensional Climate Modeling, which he co-authored with Claire L. Parkinson in 2005, is the classic graduate-level text in the field. A former head of the American Meteorological Society and an adviser to every president — Republican and Democrat alike — since Jimmy Carter, Washington has devoted his life to creating increasingly precise and accurate computer models of Earth’s climate. “What people need to understand is that these are not untested models scientists have dreamed up,” says Washington, now a senior scientist at the National Center for Atmospheric Research (NCAR). …

Evidence of climate change springs ahead with blooming wildflowers

Spring certainly seems to arrive earlier these days than it used to. But is it a sure sign of global warming or just natural variability? After decades of careful research on wildflowers, University of Maryland ecologist David Inouye has some definitive — and disturbing — answers. This summer Inouye returns to the Rocky Mountain Biological Laboratory for the 40th consecutive year to study changes in wildflower populations some 9,500 feet high in the Rocky Mountains near Crested Butte, Colo. His work offers some of the most detailed understanding yet about climate change and its effects on alpine plant and animal …

Are butterflies the silent harbingers of global warming?

Camille Parmesan studies the effects of global warming by chasing butterflies. Sounds fanciful, but it is anything but. Her careful field observations of butterfly populations have produced compelling evidence of how climate change has already affected our living planet. In several landmark studies, she has helped pave the way for a body of eye-opening research that has tracked changes in numerous populations of plants and animals. It all started back in the early 1990s, when Parmesan was a graduate student happily studying the diet of the Edith’s checkerspot butterfly (Euphydryas editha). She was drawn into the field by her love …

Tracking surface water on a warming planet

Keith Cherkauer studies mud. It’s a dirty business that has revealed a lot about global warming. As he trudged through rural Indiana farmland earlier this spring, Cherkauer, an agricultural and biological engineer at Purdue University, paid close attention to the way his boots sank more than an inch into the mud before they reached the solidly frozen soil below. The way surface water travels under these soil conditions fascinates Cherkauer — and worries him too. For the past decade, he has been monitoring soil temperatures and patterns of freezing and thawing in the upper midwestern region of the United States. …

Glacier gumshoe seeks secrets of climate change in ice

It takes a certain kind of person to gather ice cores from remote glaciers, cart them back to a lab, and unlock the clues they contain about the climate record. Such a person needs to be hardy and skilled enough in the field to lead expeditions loaded with equipment into some of the world’s most rugged-and frigid-mountain terrain. Back at the lab, this person needs technical acumen and a meticulous attention to detail in order to measure the cores’ trace chemicals down to the parts-per-trillion level. To be a glacial detective, in other words, a person needs to be a …
