A climate change for ‘glaciogenic’ art

A climate change for ‘glaciogenic’ art

By Lakshmi Chandrasekaran Glaciers and forests show jagged retreats in Jill Pelto’s paintings while the sky above heats up. Pelto, a graduate student studying climate science at the University of Maine, uses her art to convey the impacts of climate change on world environments. She overlays climate change research data with striking colors and vivid…Read More

Cosmic rays from the galaxy help track retreat of glaciers on Earth

Cosmic rays from the galaxy help track retreat of glaciers on Earth

By Lakshmi Chandrasekaran Cosmic rays, hurling across the galaxy near light-speed, generate a time machine on Earth for us to measure the retreat of the glaciers and the pace of climate change. Ph.D. student Peter Strand, at the University of Maine, drilled samples of quartz from boulders in Mongolia’s Altai Mountains this summer to tap…Read More

Artificial trees might be needed to offset carbon dioxide emissions

Artificial trees might be needed to offset carbon dioxide emissions

By Janice Cantieri Physicist and engineer Klaus Lackner makes artificial trees – but not the kind that decorate living rooms and lobbies. His artificial trees can capture carbon dioxide directly out of the air—and they’re 1,000 times more efficient than nature’s trees in doing so. Millions of the trees could eventually generate “negative carbon emissions,”…Read More

COMER CONFERENCE EXPLORES NEW FRONTIERS OF CLIMATE CHANGE CAUSES AND IMPACTS

COMER CONFERENCE EXPLORES NEW FRONTIERS OF CLIMATE CHANGE CAUSES AND IMPACTS

By Bryce Gray, Sarah Kramer, Neil Murthy, Danielle Prieur, Kevin Stark and Jia You – As the leaves turn gold in southwest Wisconsin each fall, climate scientists from around the world gather there to share their latest findings on the causes and impacts of abrupt climate change. This Comer Family Foundation’s annual conference on abrupt climate…Read More

Fixing climate is good for the economy, says veteran climate scientist

Fixing climate is good for the economy, says veteran climate scientist

By Jia You – Richard Alley works at the forefront of climate research, interpreting the time machine of climate past locked in ice cores he collected in some of the coldest places on Earth. The University of Pennsylvania geoscientist has spent more than 10 field seasons in Antarctica, Greenland and Alaska collecting clues from the…Read More

High temperatures add new complexity to drought in the West

High temperatures add new complexity to drought in the West

By Bryce Gray – The nearly five-year drought afflicting California and Nevada has restricted water usage, emptied reservoirs to historic low levels, and even caused the land to sink in areas of extreme groundwater depletion. As Ben Hatchett will tell you, the ordeal has left climate scientists with many of the same questions as everybody…Read More

California’s past lake levels give clues to current droughts

California’s past lake levels give clues to current droughts

By Danielle Prieur – Climatologist Sidney Hemming of Columbia University first came to the Mono Lake Basin in California to assist her husband, Gary Hemming, with his research but found important links between prehistoric lake levels and current drought conditions. “I first went out there to collect water samples with my husband who was interested in…Read More

MISSIVES FROM MONGOLIA: CHASING DOWN THE ICE AGE

MISSIVES FROM MONGOLIA: CHASING DOWN THE ICE AGE

By Sarah Kramer – The Altai Mountains of western Mongolia may be concealing secret amidst the splendor. The breathtaking alpine landscape could hold clues to how abrupt climate change might have impacted our ancestors— and how it may impact our descendants. This summer, a team of scientists, students and historians trekked through the hills and…

Greenland caves could hold clues for climate change

Greenland caves could hold clues for climate change

By Bryce Gray – Clues unearthed from the northernmost caves on the planet could help plug a 10,000-year gap in Greenland’s ice core record, providing essential information about where the climate may be heading now. But perhaps spelunking climatologist Gina Moseley’s most shocking discovery from this past summer’s expedition was the abandoned army rations that expired 60 years ago…

SCIENTISTS EXPLORE BETTER WAYS TO TELL THE GLOBAL WARMING STORY

SCIENTISTS EXPLORE BETTER WAYS TO TELL THE GLOBAL WARMING STORY

By Kevin Stark – Throngs of demonstrators frustrated with government inaction on climate change filled the streets of Manhattan in fall. They wore cardboard cutout life preservers that said “preserve our communities.” They carried a giant sunflower, nearly the width of a city street. Colorful signs, young and old, a cross-section of America. And there…
