Sunlight can break plastic down into chemicals that dissolve in water

Researchers previously thought that sunlight would only ever break down plastics in the sea into microplastics – which then persist in the environment forever. But analysis of real-world bags produced by retailers showed that the effect of sunlight is often very different.


Study estimates how much coal, oil must be left in the ground to curb climate change

Researchers who estimate how much of the world's coal, oil and natural gas reserves should be left unburned to slow the increase in climate-changing gases in the atmosphere have come up with a new, bigger estimate of how much should be left in the ground.

How a laser fusion experiment unleashed an energetic burst of optimism

Scientists have come tantalizingly close to reproducing the power of the sun — albeit only in a speck of hydrogen for a fraction of a second.


Climate change is a ‘hammer hitting us on the head,’ developing nations say

Leaders of vulnerable countries, as well as activists, said Monday’s blistering United Nations report must galvanize global action. But major emitters are dragging their heels.

IPCC climate report: Profound changes are underway in Earth's oceans and ice – a lead author explains what the warnings mean

Some of the climate changes will be irreversible for millennia. But some can be slowed and even stopped if countries quickly reduce their greenhouse gas emissions, including from burning fossil fuels.

To prepare for future climate change, scientists turn to past 'tipping points'

To prepare for future climate change, researchers set out to investigate the "tipping points" that led to historic periods of society-altering climate change.

Pacific Northwest heat wave study predicts more extreme heat

A study suggests that the world can expect more record-shattering heat waves in the future, unless drastic action is taken to curb climate change.

Fauci wants to make vaccines for the next pandemic before it hits

If funded, a government program costing several billion dollars could develop “prototype” vaccines to protect against 20 families of viruses.

Rat nests contribute to fossil record in odd Wyoming cave

It's time to praise pack rats. The small rodents with big eyes are helping scientists decipher climate change deep inside a chilly Wyoming cave.


Catching fire: AI is helping scarce firefighters better predict blazes

As climate change and gaps in forest management create more intense and deadly wildfire seasons, firefighting resources are increasingly stretched to the limit. Researchers like Chris Dunn hope their tools can help ease that pressure by making sure scarce fire resources are deployed as efficiently as possible.

New extreme weather record? Not so fast

California's Death Valley recorded temperatures of 130 degrees Fahrenheit this month, a measurement that could be the highest ever reliably made on Earth.

Top US scientist on melting glaciers: ‘I’ve gone from being an ecologist to a coroner’

Diana Six, an entomologist studying beetles near Glacier national park in Montana, says the crisis has fundamentally changed her profession.

Do leaked climate reports help or hurt public understanding of global warming?

Last month's leaked IPCC report cherry picked grim scenarios, but it's just the latest in a long line of leaks intended to shape perception of climate science.
