Too much emphasis, in discussions at contemporary event blogs such as this one, get bogged down in arguments over cataclysms.

This makes for heated exchanges but overlooks the real issues of slow aridification, shifting precipitations patterns, changes in local flora, etc. that result from changing climates.

Everyone argues over a Roland Emmerich type scenario… whereas the reality we face is one of change too gradual for any Hollywood blockbuster, but still way too quick for us to adapt to with our agricultural and economic systems, not to mention the rest of biosphere.
