Several states are experimenting with weather modification to try to generate snow as water supplies shrink. An atmospheric scientist explains the history behind it – and the challenges.

Innovation made the 2022 Winter Games possible in Beijing, but snowmaking has limits in a warming climate.
In Beijing’s climate, you could coat a Sydney apartment in a few inches of snow with the same energy the air conditioning would use in an hour.
From pioneering green energy grids to mountains of fake snow.
Snowmaking machines can produce enough snow to cover a run, but artificial snow is very different from natural flakes that fall from the sky.
An analysis of 21 former Winter Olympic venues found that only one of them would be suitable and offer safe racing conditions for athletes if greenhouse gas emissions continue to rise.
Winters are getting warmer, yet Bostonians were digging out from nearly 2 feet of snow from a historic blizzard in late January. Why is the Northeast seeing more big snowstorms like this?
In order for snow to form, two distinctive weather properties are needed: cold temperatures and moist air. The Sahara can tick these boxes.
It’s hard to get accurate measurements, but a nationwide network of more than 8,000 volunteers with rulers and specific standards reports after every storm.
Preparing for being active in cold weather can help keep us safe and increase our enjoyment.
Salty water seeps into our soils and groundwater through surface runoff and storm-water pipes. The long-term storage of salt in the environment impacts aquatic life, infrastructure and drinking water.
New climate simulations show that there will be more rain and less snow falling in the Arctic by the end of the century, particularly in the fall and winter.
Researchers are uncovering how microplastic particles are carried in wind, rain and snow to remote regions of our planet.
Roof slopes in traditional Chinese architecture reflect snowfall patterns over a millennium.
As rivers run dry in the Rocky Mountains and the West, it’s easy to wonder where all the snow you see on mountain peaks goes. Some of it ends up in the air, but researchers aren’t sure how much.
Drought conditions are so bad, fish hatcheries are trucking their salmon to the ocean and ranchers are worried about having enough water for their livestock.
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.
