Atmospheric scientist Adam Sobel takes a look at what’s behind the California dam crisis that forced nearly 200,000 people to evacuate.
How did our climate system behave the last time it warmed up like it’s doing today?
Changes in the annual summer monsoon that drops rain onto East Asia likely altered the course of early human cultures in China, say the authors of a new study.
Polar scientists give Obama a warm farewell by collecting climate data in his name.
Research by Lamont’s Billy D’Andreas revealed that over the last century, glaciers in Greenland have been retreating quickly — at a rate at least twice as fast as any other time in the past 9,500 years.
Lamont geochemist Bärbel Hönisch investigates the role of the ocean and, in particular, the role of marine carbonate chemistry in global climate change.
In the far north, climate is warming two to three times faster than the global average. How will these changes affect tundra and boreal forests?
Sonya Dyhrman studies marine microbes and the role they play in producing oxygen, capturing carbon dioxide, and fueling the marine food web.
A new study says that human-induced climate change has doubled the area affected by forest fires in the U.S. West over the last 30 years.
As the Southwestern U.S. grows hotter, the risk of long-lasting megadroughts rises, passing 90% this century if greenhouse gas emissions continue at their current pace.
Ecosystem ecologist Natalie Boelman is studying the effects of climate change on the relationships among migratory songbirds, plants and insects in Alaska.
An expedition to the Canadian Arctic and west coast of Greenland is a moving and motivating experience for leading climate scientist Maureen Raymo.
Scientist Park Williams, recipient of a Climate and Life Fellowship, is examining the influence of climate change on droughts and wildfires.
Ecologist Natalie Boelman is part of a multi-year field campaign to understand the impacts of climate change in Alaska and western Canada.
In this episode of the Huffington Post’s “Talk Nerdy To Me,” Center for Climate and Life Director Peter de Menocal discusses climate change and the Anthropocene.
Earth’s own large-scale iron fertilization experiments over 500,000 years show adding iron to the equatorial Pacific surface has little effect.
Humans have been burning fossil fuels for only about 150 years, yet that has started a cascade of changes that will still be felt 10,000 years from now.
Using computer models, scientists compared our expected future with a scenario in which ozone-depleting substances had never been regulated.
One scientist is focusing on food security and climate shocks. The other is exploring the influence of climate change on droughts and wildfires.
Much of the modern understanding of climate has been shaped by pioneering studies done at Columbia University’s Lamont-Doherty Earth Observatory.
The Indonesian peat fires that have been choking cities across Southeast Asia are creating more than a local health menace—they’re releasing immense stores of CO2.
Scientists have identified 32 water basins where loss of snowpack as temperatures warm is putting the water supplies of large populations at risk.
Using tree rings, a new drought atlas maps the reach and severity of dry and wet periods across Europe and the Mediterranean over the past 2,000 years.
A new study finds that the Horn of Africa is drying at a rate that is both unusual in the context of the past 2,000 years and in step with human-influenced warming.
Ancient pollen is providing new insights into historic droughts in Southern California, including how a series of mega-droughts that changed the ecological landscape.
Since the late 1980s, the Southern Ocean’s rate of CO2 uptake appeared to have stagnated, alarming scientists. New data shows a recovery.
To understand the impact on the Amazon as global warming produces more intense and frequent droughts, we need to understand its water and carbon cycles.
A new study finds that global warming has measurably worsened the ongoing California drought and holds warnings for the future.
A new study of tree rings from Mongolia dating back more than 1,000 years confirms that recent warming in central Asia has no parallel in any known record.
A team of oceanographers says much of the heat trapped in the atmosphere by greenhouse gases is being soaked up and stored by the oceans–at least for now.
During the second half of the 21st century, the U.S. Southwest and Great Plains will face drought worse than anything seen in times ancient or modern, a new study says.
A team of scientists has published the most comprehensive picture yet of how acidity levels vary across the world’s oceans.
