As California broiled in high temperatures and drought last year, academic institutions across the country released study after study that suggested rising temperatures and less moisture were part of a new normal. Columbia University scientists showed that five centuries have passed since the Golden State has been as dry as it currently is. Read more
If you want to understand how scientists think about their subjects, sit down with a group of them and start a conversation. Two dozen middle and high school educators got that opportunity during a workshop earlier this month with scientists at Columbia University's Lamont-Doherty Earth Observatory. Read More
Hydroclimate is an increasing focus of the paleoclimate community and the last several years have seen important data products developed to study hydroclimate variability and change during the Common Era. The workshop Comparing Data and Model Estimates of Hydroclimate Variability and Change Over the Common Era discussed emerging themes. Read more
Throughout the 2016 presidential campaign, The Science Coalition is asking people to answer the question: Why should science matter to the presidential candidates? Watch responses from Jason Smerdon and Columbia University students. Watch the video
When Mount Tambora erupted in 1815, it spewed dust and sulfate aerosols into the stratosphere with a force more powerful than any eruption since. As the aerosols and particulates circulated around the globe, they cooled the planet, disrupting agriculture and leading to what became known as the “year without a summer.” Read more
Among firs and cedars high in the Sierra Nevada, scientists are using an array of instruments to monitor the health of the forest, measure the snowpack and track the water that melts and seeps into the soil. A team of scientists including Lamont-Doherty Earth Observatory's Justin Mankin and Deepti Singh studied how declines in snowpack will likely affect the water supplies of different regions around the world.

In this short audio interview, Justin Mankin, a postdoctoral fellow at Lamont-Doherty Earth Observatory and NASA Goddard Institute for Space Studies, describes how a changing climate may change the way cultures get their water in the spring and summer. Listen to the interview
Europe is warmer now than it has been at any time over the past 2,000 years, new research shows. A new study led by Lamont-Doherty Earth Observatory's Edward Cook and involving 45 scientists from 13 countries used tree-ring chronologies to develop a drought atlas of climate history in Europe and the Mediterranean.

When it comes to drought in the West, we ain’t seen nothin’ yet. That’s the conclusion from a new study that links an increasing risk of decades-long drought episodes in the western United States to human-induced climate change. The study predicts drought severity outside the bounds of what’s thought to have occurred over the past 1,000 years, based on local tree-ring records. Read More
Last week, scientists measured an average concentration of atmospheric carbon dioxide of 400 parts per million for the first time in human existence. This hour, Kathleen Dunn is joined by a climate scientist about what these levels mean for the future of the planet. Read More
