What the World Thinks of Climate Change
We all know that climate change can generate great debate in the United States. But what about the rest of the world?

A Dire Warning on Rapid Climate Change
Sea level rise from melting ice sheets in Antarctica and Greenland threatens catastrophe for coastal cities within decades unless strong measures are taken to reduce CO2 emissions from the use of fossil fuels, argues climate scientist James Hansen.

Spontaneous Clumping of Tropical Clouds
If you take a look at nearly any satellite image of clouds in the tropics, you’ll notice that the clouds tend to be organized into clusters. One specific type of cloud organization called “self-aggregation.” Self-aggregation is the tendency of tropical clouds to spontaneously clump together, solely due to interactions between the clouds and the surrounding…

How Genomics Can Help Famine-Prone Nations Weather Climate Change
A team of biologists and agronomists has identified genomic signatures in plants indicating they are resilient to stresses such as drought or toxic soils. The multi-year study, expected to help developing-world farmers, was done with sorghum, one of the world’s most common crops.

An Algorithm to Investigate Unwelcome Plankton
Computer scientists at Columbia University will work with oceanographers to understand what has caused an unusual plankton-like species to rapidly invade the Arabian Sea food chain, threatening fisheries that sustain more than 100 million people.

Sustainability Policy Is Taking Hold in China
I left China encouraged by the widespread receptivity to the theory and practice of sustainability, but aware of the huge challenge that lies ahead. As we flew from Guiyang to Beijing for the return flight home, I looked down and saw a countryside dotted with scores of windmills. The transition from a coal-based economy to…

The Pope’s Challenge on Climate Change
Pope Francis’s broad-ranging encyclical warns that we are destroying our common home and face an immense and urgent challenge to protect it. But it goes far beyond just the subject of climate change, calling for a holistic and sustainable future.

Antarctica’s Retreating Ice
While the ice sheets on West Antarctica and the Antarctic Peninsula are usually the ones to make the news in relation to climate change, recent studies have documented transformations that are taking place on the East Antarctic Ice Sheet as well. On the continent as a whole, large areas of ice have already melted and…

Glacial Earthquakes May Help Forecast Sea-Level Rise
Glacial earthquakes are produced as massive ice chunks fall off the fronts of advancing glaciers into the ocean. A new study of the quakes’ mechanics may give scientists a way to measure ice loss remotely and refine predictions of sea-level rise.
The first Earth Day in 1970 ignited a movement to stop polluting our planet. Today, our scientists and experts are tackling the most pressing challenges to achieve real-world impact. This Earth Day, join us in our commitment to realizing a just and sustainable future for our planet. Visit our Earth Day website for ideas, resources, and inspiration.
