Ask questions to clarify evidence of the factors that have caused the rise in global temperatures over the past century.
Satellites find big climate threats — ultra-emitters of methane
Eyes in the sky show many of the worst methane emitters are in countries that produce a lot of oil and gas, such as Russia and the United States.
Nuevo informe de la ONU sobre el clima: no hay tiempo que perder
En el informe de la ONU se vinculan directamente las temperaturas extremas, lluvias e incendios en todo el mundo con el clima cambiante de la Tierra.
World’s oceans have warmed to a ‘point of no return’
More than half the global ocean sees temperature extremes that 100 years ago were rare.
Let’s learn about tornadoes
Tornadoes are often spawned by thunderstorms — but can also emerge from hurricanes and wildfires.

Let’s learn about the science of the Winter Olympics
From scientific innovations to climate change and weather, there’s plenty of science to be found among the feats of amazing athleticism.
Climate change is upping the height of Earth’s lower atmosphere
The upper edge of the troposphere, the slice of sky closest to the ground, rose 50 to 60 meters (165 to 200 feet) a decade from 1980 to 2020.By Freda Kreier
Can scientists develop an icy sanctuary for Arctic life?
The final refuge for summer sea ice may also protect the creatures that depend on it. Saving it is an ambitious goal with many hurdles.By Freda Kreier
From icebergs to smoke, forecasting where dangers will drift
Smoke drifts. Fish eggs float downstream. Where such drifting things end up may seem a mystery. But research can predict where they’ll end up.
Potty-trained cows could help reduce pollution
About a dozen calves have been trained to pee in a stall. Toilet training cows on a large scale could cut down on pollution, scientists say.
Research on climate and more brings trio the 2021 physics Nobel Prize
Syukuro Manabe and Klaus Hasselmann pioneered work on simulations of Earth’s climate. Giorgio Parisi probed complex materials.
Moon’s orbital wobble can add to sea-level rise and flooding
In a dozen years or so, the tide-enhancing effects of a wobble in the moon’s orbit should lead to dramatically higher sea levels in some coastal cities.By Sid Perkins
Tiny animals survive 24,000 years in suspended animation
Tiny bdelloid rotifers awake from a 24,000-year slumber when freed from the Arctic permafrost.
