A climate scientist explains the forces behind the summer’s extreme downpours and dangerous heat waves, and why new locations will be at risk in the coming year.
Rainwater may be contaminated with chemicals and scientists are still uncertain about their effects.
As recent deluges in St. Louis and Kentucky show, flash flooding can happen in urban and rural areas, with deadly results in either setting.
Extreme downpours brought deadly flooding to the Appalachian region, just a few weeks after the destructive Yellowstone River flood.
Again, thousands of residents in Western Sydney face a life-threatening flood disaster. Obviously, nature is a major culprit – but other drivers are also at play.
In general, most people drive more safely when it rains. However, some underestimate the danger, which can increase risk.
There is a growing interest in planting small trees in urban areas. However, large trees have significant advantages.
One weather configuration has been responsible for record-breaking downpours in Australia, South America, and South Africa this year.
You can’t photograph the inside of a twister, but radar offers some clues.
Could South Africa’s recent flooding have been foreseen? It has long been a challenge for scientists and engineers around the world.
Emission of greenhouse gases is on the rise, an indication that the worst lies ahead.
This score is a massive four points higher than the year prior. But as La Niña subsides, we’ll quickly feel the long-term warming trend again, with bushfires picking back up next season.
Parts of southeast Australia are inundated yet again. Clearly, short-term weather forecasts are not enough to protect communities in times like these.
In a damp or water-damaged environment, toxic mould species grow and release spores that can cause health problems if inhaled.
In order for snow to form, two distinctive weather properties are needed: cold temperatures and moist air. The Sahara can tick these boxes.
Preparing for being active in cold weather can help keep us safe and increase our enjoyment.
Extended periods of rain are most likely found in locations where mountains are near oceans.
After one La Niña, the Pacific sometimes retains cool water which enables a second La Niña to form.
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.
An atmospheric river is a band of warm, moisture-laden air many hundreds of kilometres long and hundreds of kilometres wide. It can dump prodigious amounts of rain over a large area.
