Today's weather is the story of a day; climate is the story of decades. And that story of decades is changing now.

What happens with no blanket, with one, and with one too thick? Drag the blanket with your finger to change its thickness.

Run from 1900 to 2100. Watch the mountain top and the seashore together.

Drag each into what makes the blanket thicker and what does not.
