Why a mysteriously placed rainbow made perfect symbolic sense – and how weather experts knew the exact date that it appeared.
Get ready for heavier rain.
As the planet warms, the amount of moisture in the atmosphere is increasing. This will cause a lot more heavy rainfall, even in areas that are becoming drier.
Very powerful, try to avoid.
Lightning strikes are powerful – but we haven't had solid estimates of their energy until now. Researchers turned to the hollow stone tubes they create by vaporizing sand for more precise calculations.

High temperatures make droughts worse, right? Wrong: it's the other way around. Ahead of an El Niño summer that looks set to bring drought to much of Australia, here's a quick primer on how they form.
Storm clouds for California?
El Niño explained: how it works, what a mega El Niño this year could bring and how global warming might affect future El Niño-driven weather patterns.
Even another 85 years of global warming won’t stop the odd cold, snowy winter.

Parts of the UK are sizzling thanks to Iberian air.
Luckily, we have more to go on now than just knowing the tracks of previous named storms.
We're no longer caught off guard when hurricanes make landfall, the way people were into the early 1900s. Better communications, measurements and observations all feed into better forecasts and more warning.
A broken paddle on parched earth, one result of four years of drought in California.
What explains the unusually dry and warm weather that's behind California's prolonged drought? And how is climate change contributing?
California has been inundated with stranded, hungry sea lion pups, a result of warm waters causing fish to move.
The "warm blob" of remarkably warm water in the Pacific is changing weather patterns and impacting marine life, providing clues to how ecosystems may change in a warmer future.
Calm after the storm in New York City.
“Snowmageddon” was predicted – three feet of snow, blizzards whipped up by high winds, a freeze of the whole transport system. What New York got was “snowperbole”. Yes, it snowed, but not as badly as predicted…

This year could well see a new record set for the extent of Antarctic sea ice – hot on the heels of last year’s record, which in turn is part of a puzzling 33-year trend in increasing sea ice around Antarctica…
Goldilocks was onto something.
The human body operates at an average internal temperature of 37°C, give or take various fluctuations during the day. But too much or too little external heat can exacerbate certain health conditions…
