Earth’s own large-scale iron fertilization experiments over 500,000 years show adding iron to the equatorial Pacific surface has little effect.
The World Surf League is providing $1.5 million in first-year funding for ocean science at Lamont as part of an innovative new philanthropy called WSL PURE.
The Ozarks are some of the country’s most productive forests. They also sit in a warming “hole”, where temperature rise hasn’t yet taken hold.
A new citizen science project turns surfers and other ocean enthusiasts into the eyes of scientists studying the world’s coral reefs.
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.
Mesoscale turbulence is where most of the kinetic energy in the oceans can be found, and it may play powerful roles in the global climate.
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.
A new study uses sediment cores to track the expansion and retreat of glaciers through time and finds they are more sensitive than realized.
As excess carbon dioxide is absorbed into the oceans, it is starting to have profound effects on marine life, from oysters to tiny snails at the base of the food chain.
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.
As global temperatures rise, knowing just how far Greenland’s ice sheet shrank in the past could help scientists predict sea level rise in the future.
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.
Iceland has seen fast-rising temperatures since the 1970s, and glaciers–a big source of runoff for hydropower–are visibly receding.
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.
