We have to face the reality of climate change. It is arguably the biggest threat we are facing today.

Climate change is the Everest of all problems, the thorniest challenge facing humankind.

In my view, the great long-term challenges today, apart from the most urgent need to tackle climate change, is creating meaningful employment for young people.

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.
