This spring, IRI implemented a new methodology for seasonal temperature and precipitation forecasts. We asked Simon Mason, Andrew Robertson and Tony Barnston, senior climate scientists who lead the development and tailoring of IRI’s forecasts, to answer some fundamental questions about the new forecast.
As the world warms due to human-induced climate change, many scientists have been projecting that global rainfall patterns will shift. In the latest such study, two leading researchers map out how seasonal shifts may affect water resources across the planet.
A new analysis of global satellite observations shows that vegetation can powerfully alter atmospheric patterns that influence climate and weather.
A new global study has found that the number of lawsuits involving climate change has tripled since 2014, with the United States leading the way.
A young researcher explains why she is taking to advocacy for science.
Glaciers around the world have retreated at unprecedented rates and some have disappeared altogether. The melting of glaciers will affect drinking water supplies, water needed to grow food and supply energy, as well as global sea levels.
On May 2, 2017, Lamont-Doherty Earth Observatory and the Tamer Center for Social Enterprise at Columbia Business School will co-host conference for climate scientists and business and finance leaders to discuss to how a science-based approach can inform and guide investment decisions.
In the first such continent-wide survey, scientists have found extensive drainages of meltwater flowing over parts of Antarctica’s ice during the brief summer. Many of the newly mapped drainages are not new, but the fact they exist at all is significant; they appear to proliferate with small upswings in temperature, so warming projected for this century could quickly magnify their influence on sea level.
On every continent and ocean, Earth Institute field researchers are studying the dynamics of climate, geology, natural hazards, ecology and other subjects with direct applications to the challenges facing humanity.
Up to now, it has been a mystery why much of the fresh water resulting from the melting of Antarctic ice shelves ends up in the depths instead of floating above saltier, denser ocean waters. Scientists working along one major ice shelf believe they have found the answer.
