Once mercury is emitted into the atmosphere from the smokestacks of power plants, the pollutant has a complicated trajectory; even after it settles onto land and sinks into oceans, mercury can be re-emitted back into the atmosphere repeatedly. This so-called...

Oceans have absorbed up to 30 percent of human-made carbon dioxide around the world, storing dissolved carbon for hundreds of years. As the uptake of carbon dioxide has increased in the last century, so has the acidity of oceans worldwide. Since pre-...
Reducing global greenhouse gas emissions could have big benefits in the U.S., according to a report released today by the U.S. Environmental Protection Agency (EPA), including thousands of avoided deaths from extreme heat, billions of dollars in saved infrastructure expenses, and prevented...

Overview
Researchers from MIT and Tsinghua University in Beijing are collaborating to bring new insights into how China—now the world’s largest emitter of carbon dioxide (CO2)—can reverse the rising trajectory of its CO2...
For millennia, Egypt has relied on the Nile River for its agriculture. So Egyptians were understandably upset in 2011 when their upstream neighbor, Ethiopia, announced plans to build a hydroelectric dam that threatened to reduce the flow out of the spigot: the Grand Ethiopian Renaissance Dam (...

Most economists agree that if we want to efficiently reduce CO2 emissions, we’ll need to put a price on carbon. But a nagging question remains. How are we supposed to figure out a price for an invisible, amorphous gas that underpins the economy and transforms...

According to present plans, the Grand Ethiopian Renaissance Dam (GERD) — now under construction across the Blue Nile River in Ethiopia — will be the largest hydroelectric dam in Africa, and one of the 12 largest in the world. But controversy has...

Earlier this year, weather and climate agencies around the world declared 2014 the warmest year on record, even though the increase in global mean temperature has slowed. This warming “hiatus” has puzzled climate scientists, as it deviates from climate...
The Minamata Convention on Mercury, adopted by the UN in 2013, aims to reduce global mercury pollution by setting limits on specific pollution sources and prohibiting new mercury mining. Certain aspects of the treaty are still under negotiation, for instance the convention gives nations the...
