Global Warming’s ‘Missing’ Heat: It May Be in the Indian Ocean

by | 5.20.2015 at 12:00pm
Increases in westward-blowing winds over the Pacific Ocean are thought to be pushing great masses of water--and heat--through the Indonesian straits, into the Indian Ocean.

Since the late 1990s, global warming has stabilized, even as greenhouse gases have risen. That defies simple models that say the temperature should keep going up. Many scientists think much of the heat trapped in the atmosphere by greenhouse gases is being soaked up and stored by the oceans–at least for now. A team of oceanographers now says they know where it went.

This week marks the launch of the new Columbia Initiative on Extreme Weather and Climate, a cross-disciplinary collaboration between a variety of centers, research groups and individuals from across Columbia University. The Initiative, led by Adam Sobel, kicked off on Monday evening with a World Leaders Forum panel event in Low Library. Panelists discussed a wide range of science and policy topics related to extreme weather, showing the interdisciplinary nature of the new Initiative.

NPCC's updated flood risk map

A new report gives a worrisome picture of climate-related problems the New York region will likely face this century. Temperatures are projected to rise, extreme precipitation and heat waves will be more frequent, and sea level could rise as much as 6 feet.

Glaciers in one part of West Antarctica are melting at triple the rate of a decade ago and have become the most significant contributor to sea level rise in that region, a new study says. The study found that the glaciers in the Amundsen Sea Embayment of West Antarctica have shrunk by an average of 83 gigatons a year for two decades—the equivalent of the weight of Mount Everest every two years.

Scientists at Columbia University’s Earth Institute will present important talks at the Dec. 15-19 meeting of the American Geophysical Union, the world’s largest gathering of earth and space scientists. Here is a journalists’ guide in rough chronological order.

Why are Past Surface Temperatures and CO2 Concentrations Important?

By burning fossil fuels for heating, electricity, transportation and other purposes, humans add CO2 to the atmosphere. Yet, by comparing ways in which the Earth’s temperature, CO2 concentration, sea level and ice sheets have changed in the past, we are able to learn valuable lessons about the climate system of today and tomorrow.

This fall, the photographs of Sebastião Salgado provide the springboard for an ambitious program of panel discussions, lectures and film screenings addressing the urgent issue of climate change, at the International Center of Photography in New York City.

8 Ways We Can Strengthen Development and Increase Climate Resilience

President Obama addresses the 2014 UN Climate Summit.

President Obama this week announced a set of actions designed to help populations here and abroad develop better resilience against drought, sea level rise and other consequences of a changing climate. At The Earth Institute, the International Research Institute for Climate and Society has been working on these issues for years — making regular climate forecasts, insuring farmers against bad weather, and using data to better anticipate outbreaks of disease, manage water resources and improve forest management, among other programs.
