The suffering ahead

This CNN article about global warming is very interesting and these two paragraphs caught my eye:

The report follows two studies by the IPCC earlier this year warning that unabated greenhouse gas emissions could drive global temperatures up as much as 6 degrees C (11 degrees F) by 2100, triggering a surge in ocean levels, destruction of vast numbers of species, economic devastation in tropical zones and mass human migrations.

Even the most stringent efforts outlined in the report, however, would not save the globe from suffering. An increase in temperatures to 2 degrees C (3.6 degrees F) could still subject up to 2 billion people to water shortages by 2050 and threaten extinction for 20 percent to 30 percent of the world's species, the IPCC said.

Destruction of vast numbers of species.
Economic devastation in tropical zones.
Mass human migrations.
Extinction of 20 percent to 30 percent of the world's species.

This is what we're currently looking at for our future on this planet.

Sickening, worrisome, and just plain sad.
