Extreme weather – Analysis and Comment

Flood forecasts in real-time with block-by-block data could save lives – a new machine learning method makes it possible

The majority of flood-related deaths involve vehicles in water. What if flood models could warn of the risks street by street using real-time storm forecasts? Machine learning can make it possible.

Smart meters and dynamic pricing can help consumers use electricity when it’s less costly, saving money and reducing pollution

Most households pay a flat rate 24/7 for electricity although the cost of generating it fluctuates through the day. Wireless technologies are changing that system.

Why a warming climate can bring bigger snowstorms

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?

Ocean heat is at record levels, with major consequences

While surface temperatures were about the 6th warmest on record in 2021, the upper oceans were at their hottest – and they’re a stronger indicator of global warming. A top climate scientist explains.

How Arctic warming can trigger extreme cold waves like the Texas freeze – a new study makes the connection

Counter to what you might expect, events like the February cold wave that froze Texas can actually become more likely with global warming.

Is climate change to blame for extreme weather events? Attribution science says yes, for some – here’s how it works

A new attribution study finds human-caused climate change made Europe’s July floods more likely. What about Tennessee’s flooding? An atmospheric scientist explains how scientists make the connection.

Global evidence links rise in extreme precipitation to human-driven climate change

Scientists used artificial neural networks to analyze precipitation records. They found evidence of human activities influencing extreme rainfall or snowfall around the world.

What exactly is the polar vortex?

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.
