The Earth Institute’s International Research Institute for Climate and Society makes probabilistic forecasts for rainfall and temperature for the next six months. How does it do this?
Extreme Weather and Climate
Superstorm Sandy was a wake-up call for a lot of people in New York City, including Adam Sobel, who’s spent more than two decades studying the physics of weather and climate.
California’s wet and snowy winter brings welcome relief from a years-long drought that has challenged the state’s water supply and agricultural system. But climate scientist Richard Seager of Lamont Doherty Earth Observatory offers words of caution: Remember what happened, because it will happen again.
Michelle Ho grew up in Australia, the driest inhabited continent, with an appreciation for the value of having a clean glass of water to drink. Now, she conducts research for the Columbia Water Center on America’s water systems.
Park Williams studies trees and climate, in particular the causes of drought and the effects of climate change on forests. In this latest in a series of Earth Institute videos, we spoke to him about what he does, what’s important about it, and how his interest in history and environmental science blended into a career.
In a paper published in the journal Science, researchers looked at increasing trends in the severity of tornado outbreaks, measured by the number of tornadoes per outbreak. They found that these trends are increasing fastest for the most extreme outbreaks.
As global temperatures rise and heat records are broken, many wonder if New York City’s heat waves this summer were a result of climate change, and if we will experience more of them in the future.
The heavy rains and flooding in Louisiana have been devastating. Can we attribute the severity of it to climate change? How you measure that depends on the questions you ask.
Attributing Extreme Weather to Causes—Including Climate Change
New research and more powerful computer models are advancing scientists’ ability to tease apart the forces that can worsen extreme weather. In a new report, a committee of the National Academy of Sciences that includes Columbia’s Adam Sobel assesses the young field of attribution studies.
With Chapala’s destructive landfall in Yemen just a couple of days in the past, a second tropical cyclone, Megh, has just formed in the Arabian Sea. This one is not forecast to become anywhere near as intense as Chapala did—though we know intensity forecasts can be wrong, as they were at early stages for both Chapala and Patricia.
