World Scientists Warning to Humanity

Scientists Warn of Global Dangers

Tomorrow is World Population Day. A good day to take note of the warnings coming from the world’s scientists.
“Humanity is on a collision course with Nature.
A damaged Nature will survive. We may not.
We must change course to avert an ecological disaster.”
Twenty-five years ago, 1700 scientists published a warning and recommendations for controlling environmental pollution and population growth. Except for global efforts to curtail ozone emissions, the warning had no effect. Last fall, more than 20,000 scientists issued a new warning urging efforts to change our disastrous path toward global ecosystem devastation.

The Time is Growing Short

GR:  An article from last June should be on everyone’s mind now. Here’s my discussion followed by a link to the article.

A group of scientists analyzed the sources of CO2 and the dynamic relationship between the quantity of CO2 in the atmosphere and global temperature to devise a global carbon budget they could use to assess the effect of timing of changes in CO2 emissions. The analysis enabled them to calculate the changes we must make to preserve a livable climate. You’ll have to read the article to see the individual sources of CO2 that must be adjusted. I wanted to mention the timing for the budget. The analysis shows that if CO2 emissions begin to fall immediately and reach zero in 30 years, we will remain within the global warming limits set by the Paris treaty. After the flat emissions of 2014, 2015, and 2016, the authors believed that the fall in emissions was ready to begin. This is good, because their budget shows that if we wait to 2020 to start tapering off CO2 production, we only get 20 years to reach zero emissions. If we wait to 2025, we get less than 10 years to reach zero. Transforming our energy use that quickly would be impossible.

SO, how are we doing. Six months after the analysis was published, we find that 2017 emissions have gone up, not down. Lot’s of positive changes have begun, but we have to wait to see what happens in 2018. If we begin to taper off CO2 emissions by 2020, we will have 20 years to reach zero emissions. I suggest you take a look at the six milestones the authors believe must be reached by 2020. Then you can monitor the world’s progress toward painful climate change (the Paris treaty) or disastrous climate change (with too many storms, fires, heat waves, and rising seas).

Now, let me finish by saying that climate change is just one of the approaching disasters. Human population and its impact is growing, wildlife species are going extinct at incredible rates, freshwater supplies are dropping, and toxic wastes are building up. If we can’t do more than take our CO2 emissions to zero over the next 20-30 years, most of the diversity and beauty of life on Earth will disappear.

Christiana Figueres and colleagues set out a six-point plan for turning the tide of the world’s carbon dioxide by 2020.

Illegal Pot Farms Are Fouling California Waterways with Banned Pesticides

GR: Legalizing marijuana has been a progressive goal for many years. Over the same period, illegal pot farming and distribution has been one of the nation’s largest illegal industries. Now, the industry is becoming legal. Fine; people should have freedom to make personal choices. However, the pot industry, like most other industries has no concern for the consequences of its business operations. The story below is about pesticides, but other reporters have described the loss of wilderness, wildlife, soil, and water as pot farmers shove nature aside to make a profit.

Legalizing an industry can give public (government) control over product safety and environmental abuse. Of course, the current American administration is working hard to give all industries unregulated freedom comparable to the illegal pot industry. We all hope that this is a temporary blip in public control of the irresponsible actions of the weaker members of our species and that we can reinstate regulations soon.

“Illegal cannabis grow operations are polluting California waterways with banned pesticides, according to reports from Reuters. Despite recent legalization of recreational marijuana in the state, California still accounts for over 90% of illegal grow operations within the U.S. The extent of contamination puts wildlife and drinking water at risk, necessitating increased monitoring and enforcement to stop ongoing ecological damage.

“Unreleased reports obtained by Reuters indicate the presence of pesticides, such as diazinon and carbofuran, which have been linked to a range of adverse human health outcomes. Both chemicals inhibit acetylcholinesterase (AChE), an enzyme important for the transmission of nerve impulses. When AChE is inhibited, acetylcholine accumulates leading to overstimulation of neurotransmitters, resulting in muscle weakness, confusion, and paralysis, among other symptoms. Both chemicals have also been shown to be highly toxic to birds. According to EPA reports from the 1980s, carbofuran applications contributed to the death of between one and two million birds each year. Diazinon has likewise been linked to hundreds of bird kill incidents, with reports in the 1980s involving over 23 bird species in 18 states.

“Reuters reports that law enforcement officers have been hospitalized from only touching plants or equipment contaminated with illegal pesticides. A police dog almost died from jumping in contaminated water, and there have been accounts of cows poisoned by nearby grow operations. “Carbofuran is in the water, and it’s not supposed to be,” said Mourad Gabriel, PhD, an ecologist who works with law enforcement on marijuana contamination issues to Reuters.

“According to Dr. Gabriel, half of the streams in eight watersheds known for illegal cannabis cultivation are contaminated with pesticide residues. “It’s like a layer cake,” Dr. Gabriel indicated. “They put chemical on chemical on chemical. We’ll find different chemicals in the water on different years.” Indeed, while some creeks tested clear during one season, return testing is finding new chemicals making their way into streams, likely as a result of their movement through the soil.” –Beyond Pesticides (Continue: Beyond Pesticides Daily News Blog » Blog Archive Illegal Cannabis Operations Are Fouling California Waterways with Banned Pesticides – Beyond Pesticides Daily News Blog.)

This Summer’s Gulf ‘Dead Zone’ Could Be Bigger Than Connecticut

GR:  Farms are a far greater source of toxic wastes than urban areas. Farming does it all. First, it obliterates natural habitats, second, it increases soil erosion, and third, it invites pesticide poisons that kill insects and the wildlife that depend on them. Join the Union of Concerned Scientists’ call on Congress to reject the Trump administration’s unacceptable budget cuts at the USDA, and instead vote to fully fund proven programs that keep our water clean, improve farmers’ livelihoods and help hungry families.

“Summer is almost here, and you know what that means. Sun, sand and … a watery wasteland devoid of all life? Yep, this is the time each year when a team of federal and university scientists predicts the size of the so-called dead zone that will develop in the Gulf of Mexico later in the summer. We’re waiting for that official prediction, but based on federal nitrate flux data and Midwest weather patterns this spring, it seems likely that it will be bigger than usual.

“That means a swath of marine habitat considerably larger than the state of Connecticut could be lifeless by summer’s end—a haunting prospect for coastal ecosystems, fisheries, and the men and women who earn their livelihoods from them. And the Trump administration’s budget proposal and general antagonism toward science and environmental protection are likely to make the problem worse in the future.

“Marine and coastal dead zones are the result of a phenomenon called hypoxia—a state of low dissolved oxygen that occurs when excess pollutants, such as nitrogen and phosphorus, accumulate in bodies of water. These nutrients feed blooms of algae that, when they die and decompose, deplete the oxygen in the surrounding water. Hypoxia is a silent killer, suffocating organisms that can’t escape the low-oxygen zone quickly enough, and causing others to flee.

“As we wrote a year ago when the National Oceanographic and Atmospheric Administration (NOAA) predicted an “average” (roughly Connecticut-sized) Gulf dead zone, even average is not the same as normal. Nitrogen and phosphorus can come from many sources, but the largest are due to human activity, including sewage discharges and fertilizers from farm fields running off into rivers and streams.

“In 2010, researchers at the University of Illinois showed that the problem of runoff from industrialized, corn-and-soybean intensive agriculture, with its system of underground drainage channels, dwarfs the impact of cities and other nutrient sources in the Midwest. Essentially, each year the Mississippi River and its many tributaries meandering through the Corn Belt quietly funnel a vast amount of agricultural pollution into the Gulf.” –Karen Perry Stillerman (More: This Summer’s Gulf ‘Dead Zone’ Could Be Bigger Than Connecticut.)
