It was the Seine’s rise and fall, in response to heavy rain, that inspired our current understanding of river systems.
Only clouds that are tall with big water drops can make rain, but they also stop most of the light, which makes them look grey.

The effects of climate change are being strongly felt in the North, but how caribou respond depends on what changes occur.
Rainbows get their round shape from a process called reflection.
Georgina, age 5, wants to know why rainbows are round.
The Acros Fukuoka eco-building in Fukuoka, Japan boasts one of the world’s most famous green roofs. The GRIT Lab at the University of Toronto is working to bring green roofs to the city and beyond in order to combat climate change.
Green roofs could play a critical role in helping cities cope with extreme rainfall events in the age of climate change. The roofs essentially suck up stormwater like sponges if designed properly.
New research shows Australian farmers are adapting to climate change, offsetting at least part of a climate change-induced decline.

The record floods of 1954 and 1974 still stand as Lismore's high-water marks. But Tropical Cyclone Debbie delivered her deluge far more abruptly than the rains that triggered those historic floods.

Another summer, not quite like the other summers.
We all know what to expect from summer in Australia. From December through March it will be hot, there will be storms and floods, and there will be bush fires. It’s been like that for as long as history…
Australia’s latest summer has been significant for weather and for climate.
This summer hasn’t just felt hot. It’s been hot. In fact, the summer of 2012-13 is now the hottest on record. Average temperatures beat the record set in the summer of 1997-98, and daytime maximum temperatures…
A warmer atmosphere holds more moisture, and that can lead to more extreme rainfall.

Rainfall extremes are increasing around the world, and the increase is linked to the warming of the atmosphere which has taken place since pre-industrial times. This is the conclusion of a recent study…
What does it matter how much rain falls on the ocean? For understanding climate, it matters quite a lot.
Surprising evidence from the oceans suggests they are responding to warming at a faster rate than we previously thought. These changes are expressed by patterns of freshening and enhanced salinity in the…
A mosquito being rained on is the equivalent in size, mass and force of a human being hit by a car, so how do they survive…
