It has been noted that “even before the early ancestors of modern humans began walking on 2 legs, climate change was a constant and ongoing process.
During an earlier warm era, trees and plants now common in areas of the United States were found near the North Pole.
Only 18,000 years ago most of the North American Continent was covered in ice.
From historical records a recent cooling period known as the little ice age occurred from the 15th to the 19th century.
This cooling caused a decline in human existence because of massive crop failures and hypothermia related disease.
The subsequent warming trend that began in the 19th century has been good for humans; however, for the first time in history our activities may be affecting the environment in ways that are contributing to global climate change.”
On June 14, 2014, President Obama gave the commencement speech at the University of California, Irvine.
When challenging political opposition to government policy to respond to ongoing global climate change, the President spoke as follows:
“Now, part of what’s unique about climate change, though, is the nature of some of the opposition to action.
It’s pretty rare that you’ll encounter somebody who says the problem you’re trying to solve simply doesn’t exist….
And today’s Congress, though, is full of folks who stubbornly and automatically reject the scientific evidence about climate change. They will tell you it is a hoax or a fad.”
These comments ought to resonate in Sacramento as we deal with an ongoing drought.
In May 2014, a group of academic scientists published a research paper on the probable causes of the 2013-2014 California drought. Some of its results are summarized.
Severity – California 2013 – 2014 drought was historic in minimal levels of rain
Cause – upper-level drought-producing weather ridge
Influence – intensity of drought-producing weather ridge traceable to human-induced global warming
Future – persistent and cyclic California droughts will be more severe going forward
The current drought in California will impact much of Sacramento’s economy, including increasing the price of food.
Emerging scientific evidence that this drought, and its impacts on Sacramento, is influenced by human-induced global warming compels deniers to present competent and peer-reviewed scientific evidence to the contrary.
