Earlier in the year a study from San Diego's Scripps Institution of Oceanography said that there was a 50% chance that Lake Mead would run out of usable water by 2014 as a result of climate change.
This week we heard from researchers at Colorado University that there is less than a 5% chance that Lake Mead would dry up by 2021.
For my money I would bet on the CU reseachers. Their research was presented at the USGS's shindig this week in Scottsdale and should be published next year.
Don't sell the Colorado River short. It is an ancient river and has many good days ahead of it yet.
Predicting the actual effects of climate change is even harder than showing the current effects. What we know is that the planet has a fever and that changes are coming. The discussion should be around what we need to do to reduce greenhouse gas emissions.
This week President-Elect Obama encouraged those of us that have been frustrated with the Bush administration's response to climate change. The president-elect addressed the Global Climate Summit out in California and said, "The science is beyond dispute and the facts are clear...Denial is no longer an acceptable response."
How refreshing it will be to have a president that pays attention to the science around issues rather than one spending his time politicizing agencies and muzzling government scientists.
