Mega Drought Means No More Fruits and Nuts in Califonia
by John Lawrence
California's Central Valley produces 25% of the nation's food, including 40% of the nation's fruits, nuts, and other table foods. In 2010 Bill McKibben wrote, "The federal government says that thirty-six states face water shortages in the next five years, which is bad news for farming, since 70% of the water we use goes for irrigation, and irrigated fields supply as much as 40% of the world's food. ... In California in the spring of 2009, groups of farm workers, many wearing surgical masks against the blowing dust, marched for 4 days to demand the federal government somehow supply them with more water - the year's drought had already cost the state 23,700 jobs and $477 million in revenue. Farmers are already letting orchard trees die for lack of water to keep them alive; in the Central Valley unemployment grew 9.4% in a year through July 2009. "There's no water, so there's not much work," Kiki Torres told a reporter." That was 13 years ago and since then things have only gotten worse. The problem is not only in California but around the world. Since planet earth is warming, not enough snow is falling in the Sierra Nevada mountains which forms most of California's water supply. If precipitation falls as rain, it runs off. When it falls as snow, it forms a snowpack which acts as a reservoir, that gently releases its water in the spring as the snow pack melts. This is as true in the Himalayas and the Andes as it is in the Sierra Nevada. That is why agriculture is under threat world wide, and planet earth is facing a disastrous situation when it comes to the human race being able to feed itself.
Nobel laureate Steven Chu, after being named secretary of energy, told an audience in California, "I don't think the American public has gripped in its gut what could happen. If we don't dramatically slow global warming, the rapid melt of the Sierra snowpack means we're looking at a scenario where there's no more agriculture in California." Since that speech, not only have we not dramatically slowed global warming, we have accelerated it. In an article, "Megadrought in southwestern North America is region’s driest in at least 1,200 years," Anna Novoselov reported:
"Existing climate models have shown that the current drought would have been dry even without climate change, but not to the same extent. Human-caused climate change is responsible for about 42% of the soil moisture deficit since 2000, the paper found.
"One of the primary reasons climate change is causing more severe droughts is that warmer temperatures are increasing evaporation, which dries out soil and vegetation. From 2000 to 2021, temperatures in the region were 0.91 degrees Celsius (about 1.64 degrees Fahrenheit) higher than the average from 1950 to 1999.
“Without climate change, the past 22 years would have probably still been the driest period in 300 years,” Williams said. “But it wouldn’t be holding a candle to the megadroughts of the 1500s, 1200s or 1100s.”
"As of Feb. 10 [2022], according to the U.S. Drought Monitor, 95% of the Western U.S. was experiencing drought conditions. And in summer 2021, according to the U.S. Bureau of Reclamation, two of the largest reservoirs in North America — Lake Mead and Lake Powell, both on the Colorado River — reached their lowest recorded levels."
The dire predictions of Bill McKibben's 2010 book Eaarth, have only gotten worse since the human race has failed in its responsibility to protect the planet mainly due to a lust for profits. It's the modern day equivalent of the Noah's Ark scenario, only this time the human sins are a reluctance to set the profit motive aside and do what's necessary to make sure that the planet remains a habitable environment. Instead of flooding, the worst effects more likely will be drought and a dwindling food supply. Parched earth cannot produce food. Earth's food supply is dependent on snowpacks in the Sierra Nevada and glaciers in the Himalayas. The warming planet is producing more precipitation but in the form of rain which runs off causing floods in many instances. What we need now is the equivalent of a mega rain barrel to catch the rain, since water is not going to be stored much longer in the form of ice. Snowpacks and glaciers are going the way of the dodo bird which, in case you haven't heard, has gone extinct. In addition to that the parched earth is causing more and larger forest fires which are spewing even more greenhouse gasses into the atmosphere. But not to worry. In a capitalist economy only the poor will suffer. What little food remains will be bought up by the rich.
The parched earth is also causing more forest fires releasing even more greenhouse gasses into the atmosphere. Forests act as a carbon sink. Forest fires release that carbon. Trees withdraw carbon from the atmosphere and store it. The less trees on earth, the less is the ability of the planet to withdraw greenhouse gasses with the result that global warming is sped up. The Washington Post reported in an article, Massive wildfires helped fuel global forest losses in 2021:
"Unprecedented wildfires raged across Russia in 2021, burning vast swaths of forest, sending smoke as far as the North Pole and unleashing astounding amounts of greenhouse gases into the atmosphere.
"Logging operations continued. Insect infestations wreaked havoc. The relentless expansion of agriculture, meanwhile, fueled the disappearance of critical tropical forests in Brazil and elsewhere at a rate of 10 soccer fields a minute.
"Around the globe, 2021 brought more devastating losses for the world’s forests, according to a satellite-based survey by the University of Maryland and Global Forest Watch. Earth saw more than 97,500 square miles of tree cover vanish last year, an area roughly the size of Oregon."
It's a feedback loop: less water, more parched earth, more forest fires, more greenhouse gasses released into the atmosphere, more global warming, less water. The human race has not proved itself to be that concerned about future generations which might cause it to deny itself whatever pleasures are available to the current generation. Self sacrifice is not the norm. The result is that we are sacrificing future generations and condemning them to a hellish earth.
