In a column appearing in Italy's La Repubblica, Lamont's Marco Tedesco discusses the darkening of Greenland and how that contributes to a cycle of melting. The column is written in Italian.
Global warming will require big changes in how we management water, the Desert Sun writes. “In general, what a measure like this is telling us is that our historical reliance on snow is untenable in a future climate," said Lamont's Justin Mankin.
The vast Greenland ice sheet is seeing a record-breaking level of melt for so early in the season. “The potential implications, in terms of runoff and so on, they alter the memory of the snowpack, the potential implications can be big either for the same season or future seasons,” said Lamont's Marco Tedesco.
If climate change continues, we can expect a large rise in sea level this century, and it will only get worse in the centuries to come. The BBC talks with Lamont's Maureen Raymo.
A landslide last October detected in Alaska by Lamont's Colin Stark and Göran Ekström might be the biggest non-volcanic landslide recorded in North American history. It also created a wave that sheared alders more than 500 feet up the opposite hillside.
The World Surf League just launched a non-profit, WSL PURE. It will help researchers at Columbia University's Lamont-Doherty Earth Observatory study climate change and the ocean.
The World Surf League has just launched a whole new wing of their organisation, WSL PURE. This time, it's all about giving back. The new philanthropic wing is putting $1.5 million in first-year funding into ocean science at Lamont-Doherty Earth Observatory.
“More melting creates more darkening and accelerates the melting itself — a positive feedback effect,” Lamont's Marco Tedesco said.
“You won’t open your mouth in the Hudson River, and that’s symbolic of a lot of things,” says Wade McGillis, an associate research professor at Lamont. “We want to figure out if we can restore it to a pristine system. If you don’t know what you’re doing to it, you can’t figure out ways to fix it. ”
Lamont's Adam Sobel reminds readers to differentiate between weather and climate. If you really want to know what is going on with climate change, he said, look at the long-term averages over large areas. Do not be fooled by short-term weather fluctuations.
Lamont's Robin Bell talks about the urgent need for Antarctic research. A recent study found that, with very high carbon emissions, melting ice from Antarctica could cause seas to rise 1.14 meters (3.74 feet), give or take 36 centimeters, by 2100 — and much more by 2500.
The New Yorker talks to a team of scientists, including Lamont Associate Research Professor Mike Kaplan and Adjunct Associate Research Scientist Aaron Putnam, who are researching how quickly the ice in the Himalayas is melting.
The devastation caused by earthquakes is evident all across the world, but could something like this happen in our area? Fox news talks with Jim Gaherty.
When plants respire, they contribute a massive carbon flux to the atmosphere so their response to higher temperatures is a major concern for scientists. A new study from Lamont's Kevin Griffin finds plants might not respond to warming as thought.
Higher temperatures in France are producing exceptional vintages, but the run will come to an end if global warming continues at the current rate, a new study from Lamont's Ben Cook suggests.
Carbon emissions hit a dramatic high nearly 10 million years after the demise of the dinosaurs some 66 million years ago. But emissions now far surpass that. "What we're doing today is much more extreme than what happened in Earth's history," says Lamont's Bärbel Hönisch.
Climate change has pushed French wines into uncharted territory, and could force producers to relocate or abandon the grapes that helped to make their vineyards famous, according to a study from Lamont's Ben Cook.
"Our analysis showed that wine harvests are happening earlier, which has historically been a harbinger of high-quality wines. But we also found that changing local weather conditions could make it harder to determine when to expect high-quality wines, and that higher temperatures could force wine growers to use different grape varieties," writes Lamont's Ben Cook.
A crew of scientists led by Lamont's Park Williams has been making its way through the Ozark Mountains, dodging snakes and poison ivy to study tree rings, to see how they're reacting to climate change.
"When it comes down to climate and carbon sequestration, these are global problems," says Lamont's Kevin Griffin.
