The main message we want to get out there is that climate change is caused by the rotten economic system.

Our economic system, run for profit and waste and based primarily on the extractive industries, is the cause of climate change. We have wasted the earth's treasure and we can no longer exploit it cheaply.

The main message of Climate Revolution is that climate change is caused by the rotten financial system we've got, designed to create poverty and rip off any profits for a small amount of rich people. Meanwhile, it destroys the earth.

The measurements show long-term trends. Glaciers react to climate change, and warmer temperatures in the Alps are reflected in the results.

If we let climate change run its course, this could be a fairly typical winter 30 or 40 years from now.

We're vulnerable to begin with, and climate change exacerbates the vulnerability.
