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.

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.
Paleontologists have discovered fossil remains belonging to an enormous ‘toothed’ bird that lived for a period of about 60 million years after dinosaurs.
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.
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.
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.
