Ecologist Maria Uriarte investigates the effects of Hurricane Maria on the forests of Puerto Rico, and how long-term climate change may affect them.
In a new study, researchers have mapped out a large variety of discarded pharmaceuticals dissolved throughout the Hudson River. They say that in some places, levels may be high enough to potentially affect aquatic life.
Upmanu Lall, director of the Columbia Water Center, explains South Africa’s water shortage and why places in the U.S. could be at risk, too.
Adding protective barriers around street trees could reduce load on city sewers, study finds.
The Columbia Water Center (CWC) is a leader in applying the science of water and climate to solve real world problems. With current events in mind, we worked with our partners to make progress on several key projects.
Human-influenced climate warming has already reduced rainfall and increased evaporation in the Mideast, worsening water shortages. Up to now, climate scientists had projected that rainfall could decline another 20 percent by 2100. But the Dead Sea cores suggest that things could become much worse, much faster.
Thousands of years before Biblical times, during a period when temperatures were unusually high, the lands around the Dead Sea now occupied by Israel, Jordan and surrounding nations suffered megadroughts far worse than any recorded by humans. Warming climate now threatens to return such conditions to this already hard-pressed region.
Plastic microbeads, common in soap, toothpaste and other consumer products, are flooding waters. A team from Lamont-Doherty Earth Observatory is doing the first large-scale assessment of their impact on New York’s waterways.
Now, nearing the end of our three-week cruise of the North Pacific off Hawaii, we are working to understand how these tiny bacteria connect and communicate with one another.
