Climate Change

Mining museums’ genomic treasures

The world’s natural history collections hold billions of biological specimens, many of which still contain DNA. Scientists exploring these genetic repositories are gaining new, historical perspectives on how animals evolve.

Rethinking air conditioning amid climate change

ACs and refrigerators help keep people safe — but they also further warm the planet. Scientists are working on eco-friendlier solutions as global demand for cooling grows.

Bear hibernation: More than a winter’s nap

The creatures’ annual protracted snoozes have much to tell us about the biology of mammals, ourselves included. Now scientists are watching to see how bears will tweak their habits as the climate warms.

Urban evolution: How species adapt to survive in cities

Plants and animals are evolving in cities around the world — offering ways to study longstanding scientific questions and clues to where climate change is taking us

A rise in US flooding — and a rethink

“Gray” infrastructure throws up walls against the coastal flooding affecting many cities. But salvation may lie in leaning in toward green controls like wetlands and mangroves — and heeding the experience of the Dutch.

The history of climate change offers clues to Earth’s future

PODCAST: Digging — quite literally — into our planet’s past to study its paleoclimate has shed light on bygone ice ages and hints at trouble ahead for our now-warming world (Season 2/Episode 4)

Can a fire-ravaged forest of Joshua trees be restored?

VIDEO: In August 2020, the Dome Fire burned more than 40,000 acres of the iconic species’ range in the Mojave Desert, leaving a graveyard of blackened trees. A massive replanting effort now underway hopes to return life to the fragile ecosystem by boosting numbers of the climate-threatened plant.

Lyme and other tick-borne diseases are on the rise. But why?

The complex interplay of ticks, their habitats and hosts — along with changes in land use and climate — may be enabling the spread of the pathogens they carry

How to short-circuit short-term thinking

OPINION: Human behavior is fueling major social dilemmas — from climate change to the Covid pandemic to the spread of misinformation. But that means it’s also the solution, if only we can harness psychology for the common good.

Why there’s no such thing as pristine nature

A growing body of research shows that people have been shaping the planet for millennia — muddying the very idea of wilderness and prompting calls for a revolution in ecology and conservation

Will glow-in-the-dark materials someday light our cities?

Substances that persistently luminesce are already used in some bike lanes, and in the future could be applied to sidewalks, streets and buildings — saving energy and reducing urban heat

Now is the time to prepare for the economic shocks of battling climate change

Shedding reliance on fossil fuels is key to making the leap from a carbon-intensive present to a greener future. Experts say that smart planning and transparent policymaking can ease the transition — and balance the worst financial risks.

How to handle climate anxiety

Worry over the planet’s future is taking a toll on emotional well-being, researchers say. Here’s how to cope so we don’t lose hope for our planet and for ourselves.

The case for ocean optimism

With the health of the ocean under threat, a rallying cry for marine conservation goes global. Here are some of the good-news stories.

Many mangrove restorations fail. Is there a better way?

These carbon-hoarding, coastline-protecting forests are sponges for greenhouse gases. Doing plantings right and involving local communities are key to saving them.

Let’s keep meetings virtual after Covid

OPINION: We don’t want to go back to living on planes and out of suitcases. Virtual meetings are cheaper, more accessible and better for the planet.

Fighting climate change means taking laughing gas seriously

Agriculture researchers seek ways to reduce nitrous oxide’s impact on warming

A healthy environment as a human right

UN recognition would strengthen legal arguments for preserving nature

Growing a more resilient global food system

Covid-19 has been a stress test for the world’s food supply chains — and a preview of looming threats. That’s making efforts to improve the journey from farm to fork more urgent than ever.  

Baking resilience into the food system

VIDEO: Watch our conversation about the pandemic’s effect on global food supplies and distribution, and how we might prevent future crises arising from climate change
