Tropical glaciers are melting fast: Looking for clues to climate change

Madhurita Goswami, Dec. 18, 2019 — Most of us associate glaciers with Antarctica or the northern ice-sheets of the Arctic and Greenland. It may come as a surprise that scientists Alice M. Doughty and Meredith Kelly are studying tropical glaciers at the Rwenzori Mountains of Uganda to improve our understanding of climate change. The Rwenzori…Read More

Climate science pioneer Wallace Broecker memorialized at namesake symposium

Zack Fishman, Dec. 18, 2019 — The locked office of the late climate scientist Wallace “Wally” Broecker displays a wooden ship’s wheel, mounted on a window-paneled wall behind his former desk. The wheel overlooks the forested campus of Columbia University’s Lamont-Doherty Earth Observatory, where Broecker conducted research for nearly 70 years. It originated from one…Read More

4,000 floating robots take on climate change

By Elena Bruess, Oct. 16, 2019 – I ziplined recently with a scientist who told me that her work involved almost 4,000 floating robots and a massive global computer database that could help her predict the future of our world’s climate. This was during a break in the Comer Climate Conference and the woods behind…Read More

Khumbu Glacier in Nepal offers clues to rapid retreat of ice

By Anne Snabes, Dec. 19, 2019 – The Khumbu Glacier in the Himalayas retreated rapidly in the past, offering clues to how the glacier will behave in the future, University of Maine research suggests. Laura Mattas, a master’s student at the university, conducted field research this summer on the Khumbu Glacier in Nepal. She presented…Read More

Tiny shells reveal clues to ocean health in North Pacific

By Anne Snabes, Dec. 19, 2019 – Calcium carbonate, a primary ingredient in the shells of tiny marine organisms, reduces the acidification of our world’s oceans. The ocean is approximately 30% more acidic than when the Industrial Revolution began, and carbon dioxide emissions from human use of fossil fuels have greatly contributed to this increase.…Read More

Renowned geoscientist talks climate research, renewable solutions

By Zack Fishman, Oct. 29, 2019 — Richard Alley caught a cold while flying to southwest Wisconsin for the annual Comer Climate Conference land, hosted each fall by the Comer Family Foundation. But the illness didn’t stop the seasoned scientist from celebrating each research presentation with emphatic words of encouragement, and he used his closing…Read More

Greenland ‘ice tongue’ at risk of melting away — again

By Zack Fishman, Nov. 12, 2019 — A 30-mile-long strip of sea ice in northwest Greenland, once thought to be a permanent structure, didn’t exist until 2,000 years ago, according to newly published research from researchers at Oregon State University. The findings suggest that some of the Arctic may melt more quickly in today’s warming…

Fox in the field: Following the tracks of climate triggers in Mongolia

By Stephanie Fox, August 20, 2019 – I should probably explain that headline. In mid-July, I left my Illinois home and headed to Chicago’s O’Hare International Airport. That’s where I met up with two scientists, a high school teacher and a rising university freshman. Together we boarded a plane to Beijing, China, then Ulaanbaatar, Mongolia,…

Safety requirements for Antarctic climate scientists can take your wisdom teeth

By Stephanie Fox, Jan. 12, 2019– What do Antarctic climate scientists and Nordic Vikings have in common? More than you’d think. After being cast out of Iceland for murdering his neighbor, Erik the Red, the notorious Viking who walked the Earth around 985 A.D., braved the unforgiving seas in search of a new home. That’s…

WHAT CAN WE DO TO SLOW CLIMATE CHANGE?

WHAT CAN WE DO TO SLOW CLIMATE CHANGE?

By Karyn Simpson, Dec. 20, 2018 – Columbia University Geology Professor Wally Broecker, the pioneering grandfather of climate science, laid it on the line. The two ways we know of to bring down civilization are nuclear bombs or carbon dioxide emissions from fossil fuels, the driving force of climate change, he said this fall during…

HOW MUCH CARBON DIOXIDE CAN WE LOCK IN THE DEEP OCEANS?

Aaron Dorman, Dec. 16, 2018 – Natural ocean biology can help remove carbon dioxide from the atmosphere by trapping it in surface algae that sinks to the bottom of the sea. That’s the focus of research by two Columbia University scientists. These studies concluded that iron fertilization of the oceans surrounding Antarctica had occurred in…

RESEARCHERS AGREE – TAXING CARBON EMISSIONS OFFERS A SOLUTION TO CLIMATE CHANGE

By Valerie Nikolas, Nov. 13, 2018 – “We have to put a price on carbon,” Columbia University scientist Wallace Broecker, the geoclimatologist who coined the phrase “global warming” in a 1975 study, said at the Comer Climate Conference held in southwestern Wisconsin in early October. The latest United Nations’ climate change report and the Nobel…

“LAKE MAFIA” GETS TOUGH ON CLIMATE CHANGE

Aaron Dorman Medill Reports, Oct. 31, 2018 – An alpine forest turns into a desert within a mere 16,000 years – the geologic equivalent of a blink of an eye. The transformation is just one climate mystery waiting to be solved. Wondering what drives local rainfall? Curious about tipping points for the entire global weather…
