Trees and shrubs in cold-weather climates rely on certain signals, such as temperature and light, to know when to leaf out and bloom. Climate change is scrambling those signals.
Arctic foxes have a few special talents that help them sneak up on unseen prey and pounce.
The media often call unusually cold, snowy storms a 'polar vortex.' The real polar vortex isn't coming down to visit the lower 48, but changes to the polar vortex can influence winter weather.
De-icing salts help us get around in winter, but they corrode cars, crack roads and contaminate rivers and lakes. Scientists are working to develop better options by imitating natural antifreezes.
New research shows that permafrost contains huge amounts of particles that make it easier for cloud moisture to freeze. Thawing permafrost is releasing these ice-nucleating particles.
Food shortages, festivities and far-off fighting – Britain's coldest winters were among its most memorable.
Since 1979, the average number of snow days has fallen by about five per decade.
Paleontologists have discovered fossil remains belonging to an enormous 'toothed' bird that lived for a period of about 60 million years after dinosaurs.
Try a few star jumps every hour, it'll make a massive difference to your warmth.
The Arctic is warming about twice as fast as the planet as a whole, with serious consequences. Scientists have been warning about this for decades.
If you're lucky enough to be able to afford a ski trip, expect it to look different this year. Some extra planning, however, can lower the coronavirus risk to you, your loved ones and the community.
Older records can tell us a lot about Australia's pre-industrial climate, before the large-scale burning of fossil fuels tainted global temperature records.
You might have already felt what it would be like inside a cloud made of condensed water vapor.
Shovelling snow is excellent exercise that works the upper and lower body. However, it's important to remember that digging out from a storm pushes many people to their maximal fitness capacity.
Earth's biggest rivers are streams of warm water vapor in the atmosphere that can cause huge rain and snowfall over land. Climate change is making them longer, wetter and stronger.
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.
