Regarding Allen Best’s April 7 column, “An unsolved math problem on the Colorado River”:
The issue of future western U.S. (west of the 100th meridian) water supplies in a naturally dry climate with well documented recurring periods of drought certainly deserves careful consideration and advance planning for conservation and adaptation.
Examination of historical versus current flow amounts, possibly severe future flow shortages and the dual problems of over allocation and over use are known issues that have been in discussion for a good number of years. Hopefully discussions will continue to flow (pun intended) in the right direction.
However, linking the hula-hoop science of climate change alarmism to drought conditions that may or may not be any longer or severe than what has occurred in the past along with what can only be called a dubious claim about a supposedly in-the-books temperature increase and what is to be expected in some unknown future seems like a bit of headline grabbing, rife speculation.
The author states temperatures have risen by 3 degrees Celsius (5.4 degrees Fahrenheit) since 1970. He does not say where this is reputed to have occurred nor how the measurement was taken, verified and validated. That’s a whole lot of historically, unprecedented increase in temperature in an unprecedentedly short period of time.
Per widely circulated, pessimistic proclamations from the purveyors of climate alarmism, an increase in temperature of more than 1.5 degrees Celsius from the 1880 pre-industrial level is believed to be a no-turning-back tipping point. Despite the fact that, per published reports from within the European Union, we may have already surpassed this end-of-the-world temperature increase, life in the western U.S. goes on as we enter a not unexpected period of hardly unprecedented warming.
Recent years only qualify as the hottest “on record” because activists define “the record” as merely the past 140 or so years. About 150+ years ago, the Earth emerged from the Little Ice Age, which was the coldest period of the past 10,000 years. As temperatures continue their recovery from the Little Ice Age, temperatures should naturally set new “records” on a regular basis. Before the Little Ice Age, and during most of the time period that human civilization has existed, temperatures were warmer than today, CO2 levels were higher and the climate may have also been wetter. It is more likely for our climate to be wetter when it’s warmer.
