Solar and wind generators have suddenly become just as cheap as other ways to produce electric power
Through dust, not rust, the metal plays a complex, controversial role in Earth’s climate
COMIC: The reef-builders face larger threats, scientists say. Chief among these is warming seas.
To slow or stop global warming, the world agrees it must cut carbon dioxide emissions. But monitoring each nation’s output of greenhouse gases is not always straightforward.

Are we supposed to take care of the planet or should it take care of us? Willis Jenkins explains how religion shapes the conflicting views over climate change and other environmental issues.
Complex mathematical tools are aiding the battle to identify invasive species before they get a foothold in the environment. But bureaucracy can blunt the techniques.
Revolutionary techniques using traces of environmental DNA are analyzing entire ecosystems “from microbes to whales”
The humble bivalves can clean polluted water and bump up diversity — but in dammed rivers and fouled watersheds, many species face extinction. With help, maybe they can save themselves.
To understand what might be lost, ecologist Janet K. Jansson taps molecular methods to explore Earth’s underground microbes, from the permafrost to the grasslands
Agricultural economists are homing in on hybrid, low-input methods that will both safeguard the environment and feed the future billions
Feeding the planet — now and tomorrow — is no small task. Plant biologist Pamela Ronald says sustainability means using every tool in the toolbox.
Earth-friendly certifications and standards abound for products like coffee, chocolate and palm oil. But do the programs work?
Researchers probe the weather-like physics of deadly infernos
The only way for humanity to solve its environmental problems may be to abandon our quest for continual economic expansion. It’s time to study what a future of degrowth might look like, some researchers say.
After 100 years as a national park and eons as a geological wonder, the American icon continues to reveal layers of its past and of the landscape ahead
