Around three billion people worldwide depend on rice for their diet. But a new study finds that rice and other crops grown under high levels of atmospheric carbon dioxide results in lower levels of some nutrients.

New Research

More Carbon Dioxide in the Air Makes Some Crops Less Nutritious

Crops such as rice and wheat have lower concentrations of some nutrients when they’re grown under an atmosphere with higher levels of the greenhouse gas

An experiment with corals taken from the warm waters of the U.S. National Park of American Samoa showed that at least one species can quickly adapt to rising heat.

This Coral Has Shown It Can Weather Warmer Waters

Corals are not expected to do well with climate change. But the ability to adapt to warmer oceans could give them more time

Phoenix glows even after 10 p.m. one April night in this image made with a camera sensitive to infrared light, which is generated by heat and invisible to the naked eye. Researchers call the city an “urban heat island.”

The Reality of a Hotter World is Already Here

As global warming makes sizzling temperatures more common, will human beings be able to keep their cool? New research suggests not

Antarctica Was Once As Warm As Sunny California

Nearby polar regions got up to Florida-level temperatures

As climate change makes wet places wetter and dry areas drier, the frequency of drought is expected in increase in certain locations. Droughts, such as this one in Kenya in 2006, can increase food insecurity, especially among the poor.

Eight Ways That Climate Change Hurts Humans

From floods and droughts to increases in violent conflict, climate change is taking a toll on the planet’s population

Small island nations such as Tuvalu in the South Pacific face a wide range of threats from climate change, including rising seas that will inundate the land.

Five Frightening Observations From the Latest International Climate Change Report

Adaptation cannot save us from all the negative impacts of pumping greenhouse gases into the atmosphere

The Weddell Sea is covered in ice during the Antarctic winter. But in the winters of the mid-1970s, satellite imagery detected a large-ice free area the size of New Zealand.

The Northern Hemisphere's mid-latitudes have experienced many heat waves in recent years, such as one that fueled Rocky Mountain wildfires in summer 2012. Warmer-than-normal temperatures appear red in this NASA image of North America on June 28, 2012.

Summer Heat Waves May Be Linked To Sea Ice Loss

As ice melts, the jet stream gets stuck in the north, causing warm weather to linger in the south—but the reason why this occurs remains unknown
