Spring earlier than it was 30 years ago

The international Intergovernmental Panel on Climate Change has another session coming up. It starts Monday in Brussels, no foolin'. And they'll come out with another report. This one will outline effects already seen from climate change and what's expected.

CNET News.com's Zamir Haider interviewed one American member of that panel, Professor Terry Root of Stanford University. Root outlined some specific changes that have been measured. It may sound like good news: spring's now three weeks earlier than it was three decades ago.

But all that extra heat is causing severe problems for some animals with limited ranges. There'll be more extinctions. And change is paving the way for some "tropical" diseases to move north. Malaria. Dengue fever. Hantavirus. She makes it sound like the future is looking sick.
