Anyone with a sense of the 4.5 billion-year history of climate and geological change on our planet knows that change is the only true global constant. Global warming is re-structuring the world's climate zones, with some estimates that by 2100 polar and mountain climates disappearing altogether and formerly unknown ones emerging in the tropics (keep in mind that the Antarctic was once a tropical life-zone).
When climate zones shift, the animals and plants that live in them will be at greater risk of extinction, said Jack Williams, a geographer at the University of Wisconsin-Madison.
"What we've shown is these climates disappear, not just regionally,
but they're disappearing from the global set of climates, and the
species that live in these climates really have nowhere to go as the
system changes," according to Williams.
Acclerating climate change will also lead to dramatic shifts in the
behavior of nation states and the human species as a whole. I've listed
recent posts on climate change and global warming.
