For us that love the winter in southern Vermont, this winter season has been a challenge. There is not enough snow for cross-country skiing or snowmobiling, and it’s been a bit too warm for safely skating on the lakes. This is just the luck of the draw for this year’s weather, although the most recent regional climate assessment out of the University of New Hampshire states that there is a documented climatic trend of warmer winters, resulting in wetter and heavier snowfalls and a higher likelihood of icing.
And although some of us bemoan this new climate normal, there is an even greater storm, or lack thereof, on the horizon. The Washington Post recently highlighted an Arizona town whose neighborhood’s water supply had been cut off due to the extended drought. This is just the first ripple for all the states that receive water from the Colorado River. According to Scientific American, the entire Colorado Plateau is in the longest drought that it has experienced in more than 1,200 years and the National Oceanic and Atmospheric Administration projects that future climate conditions for this area of the country will be warmer temperatures, less snow-pack and higher frequency of extreme droughts.
So why should we be concerned way over here on the Connecticut River? Well, according to the US Department of Agriculture, approximately 50 percent of the products we consume, such as beans, lettuce, tree fruit and nuts, come from this region, especially from the states of Arizona and California and even parts of northern Mexico. USDA adds that this is a region where 92 percent of its agriculture requires irrigation. Irrigated water also supplies the feed for the livestock in these and other Southwestern states.
The major source of this irrigated water is the Colorado River, a river watershed with a water deficit so great that both the large reservoirs associated with the river’s Hoover and Glen Canyon dams have dropped to such low levels that “dead zones” are forming behind the dams, which is due to the lack of biologically life-saving oxygenated waters coming from upstream. Concurrently, as the water levels continue to drop behind these hydroelectric dams, they will soon be so low that water will not be able to be diverted to the electric turbines. A recent study by Power Consulting said with the loss of hydro-power due to the large-scale drought, the western power grid is poised to experience blackouts.
The overarching Federal agency that determines how much water each state can receive from the Colorado River has told the receiver states that they need to cut their demand drastically and immediately. If these states take no action, the water flow will be reduced to these states, not only impacting agriculture but cities as well. So, if you see in the not too distant future an inflationary jump in the price of your fresh produce and meat, or you start to hear of disruption to industries that are highly dependent on electricity, such as the servers that provide the nation its computer cloud storage, you might begin to connect the dots between the driver that dumps that hard-to-shovel wet snow here is intimately linked to those dry, hot-scorching days there.
