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.
A leap and a plunge into the snow could earn this arctic fox its supper.

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.
Deicing salts keep winter roads passable but do a lot of harm in the process.

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.
Permafrost is thawing across the Arctic, releasing microbes and organic materials that have been trapped in the frozen ground for thousands of years.

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.

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.
This Arctic heat wave has been unusually long-lived. The darkest reds on this map of the Arctic are areas that were more than 14 degrees Fahrenheit warmer in the spring of 2020 compared to the recent 15-year average.

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.
They may look comfy to sit on but you’d plummet through and hit the ground.

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.
As climate change intensifies, much of the nation’s building stock will need upgrading to strengthen it against flooding, snowstorms and other weather hazards.
Snow fell during the AFL match between the GWS Giants and the Hawthorn Hawks at the UNSW Canberra Oval.

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.
The air up high is just really bad at ‘holding’ onto the radiation coming from the Sun, and the warmth passes straight through it on its journey toward the ground.
