The reduced flow of the Colorado river has nothing to do with global warming. It has everything to do with the population & development boom in the southwest. Increasing demand, not decreasing supply. Of course, the MSM just has to get their plug in there for ManBearPig.
Our population explosion and development boom is going to cause all kinds of environmental problems, health problems, and shortages leading to an increased cost of resources. Just look at the increasing demand for oil. All the alternative energy sources in the world will not offset demand due to growth in population. But hey, let’s just keep bringing in the millions a year across our borders because after all, that’s not our biggest threat.
There is indeed decreasing supply as well as increasing demand.
However, there have been routinely decades-long droughts in the Colorado basin going back thousands of years.
Unfortunately, the 20th Century was a period of unusually stable and high rainfall in the basin, and this is when it was settled. People got used to a “normal” that wasn’t normal at all.
