The arduous task of cleaning up from catastrophic flooding is underway across the Northeast after storms stretched the region’s flood control systems nearly to the breaking point.
As scorching heat grips large swaths of the Earth, a lot of people are trying to put the extreme temperatures into context and asking: When was it ever this hot before?
A heat dome occurs when a persistent region of high pressure traps heat over an area. The heat dome can stretch over several states and linger for days to weeks, leaving the people, crops and animals below to suffer through stagnant, hot air that can feel like an oven.
Flash droughts develop fast, and when they hit at the wrong time, they can devastate a region’s agriculture.
A century ago, English mathematician Lewis Fry Richardson proposed a startling idea for that time: constructing a systematic process based on math for predicting the weather. In his 1922 book, “Weather Prediction By Numerical Process,” Richardson tried to write an equation that he could use to solve the dynamics of the atmosphere based on hand calculations.
As winds and waves from Typhoon Merbok devastated communities along the coast of Western Alaska in 2022, Reppi Swan Sr.’s phone began to ring at Kivalina, a barrier island 80 miles above the Arctic Circle.
If it seems like extreme weather disasters such as hurricanes and wildfires are becoming more frequent, severe and costly, it’s because they are. And that trend is influencing people’s movements.

If you want to track changes in the Amazon rainforest, see the full expanse of a hurricane or figure out where people need help after a disaster, it’s much easier to do with the view from a satellite orbiting a few hundred miles above Earth.
Meteorologists have gotten a lot better at forecasting the conditions that make tornadoes more likely. But predicting exactly which thunderstorms will produce a tornado and when is harder, and that’s where a lot of severe weather research is focused today. Often, you’ll have a line of thunderstorms in an environment that looks favorable for tornadoes, and one storm might produce a tornado but the others don’t.
