We built this tool for people to enjoy (and we hope you did!), but also to highlight something important.

14 of the 15 hottest years on record have occurred since 2000 - and 2015 was the hottest of the lot.

Human-made climate change is changing our weather at an alarming rate.

What does that mean?

That means more floods...

...more droughts...

...and more devastating storms.

We need to break free from fossil fuels to save the planet.

Will you join our campaign to make the Nobel Foundation cut its funding for the fossil fuels industry?
