In the years to come, the combination of climate change and population growth could have a devastating effect on the planet and, needless to say, on humanity.

The world that you and I live in is increasingly challenged. Population growth, pollution, over-consumption, unsustainable patterns, social conflict, climate change, loss of nature... these are not good stories.

Today's voguish threats, including climate change, population growth, massive war, and resource depletion, are all amenable to a fix if we act prudently. And even if we don't, these problems are incapable of obliterating all of humanity, let alone destroying the Earth. No, the real End of Days will happen slowly, as the Sun ages.

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.
