Love it or hate it, winter means snow and ice for much of the US. In many places, though, snow is becoming a scarce resource.
As climate change intensifies, much of the nation's building stock will need upgrading to strengthen it against flooding, snowstorms and other weather hazards.
Cold fronts swept south-eastern Australia, bringing snow and freezing temperatures. While snow is expected to decrease with climate change, cold snaps are likely to keep coming.
New research forecasts that climate change will make multiyear stretches with low snow levels more common across western North America – bad news for water managers, farmers, foresters and skiers.
It helps if you imagine the ground here on Earth as a big heater. It keeps us warm, and if you move away from the heater you feel cold.
Patching concrete sidewalks, roads and bridges after every season of snow and ice is expensive. A team of engineers is now testing a new approach harnessing bacteria to patch the potholes and cracks.
A climatologist who studies precipitation trends explains how climate change is projected to make flooding events in the Midwest more severe and more frequent.
When it snows, it pours – but why do municipalities treat the roads with salt? A chemist explains how salt affects water and ice.
Layering on winter gear is annoying. But with temperatures reaching minus 50 in some parts of the country, it is essential to protect your skin from frostbite, which can happen in minutes.
An atmospheric scientist explains why water can do some strange-looking things at very cold temperatures, and what's different about snowfalls on Mars.
Awe-filled learning unfolds as a kindergarten class, accompanied by educators, investigates snow and water with tools, toboggans and more.
Climate change is shrinking winter snow cover in Northeast forests, which protects tree roots and soil from repeated freezing and thawing. This could stunt tree growth and forest carbon storage.
Technology can only go so far in making sense of our vast and intricate atmosphere.
Rapidly dropping temperatures, rain and wind are hitting south-eastern Australia, due to a perfect combination of warm seas and low-pressure systems.
Governments and private companies have been seeding clouds to create snow for decades, without proof that it actually works. A recent study peered into clouds in search of answers.
No matter how cold it is, you're lucky you don't live on Venus.
Halfpipe snowboarders like Scotty James may seem laid-back and relaxed, but they are subjected to high physical load and fatigue induced by training and competition.
The US was hit by a 'bomb cyclone' last week, bringing icy cold and driving snow. These storms develop very rapidly, forming outside the tropics, typically on continental east coasts in winter.
Scientists used to believe that snowfall could never reach the ground.
A reliable water supply from Australia's mountain catchments depends on intact and functioning ecosystems.
