Why “Environmental” Groups Have Gone Mad

I am sure that I have long since been ex-communicated by most “environmental” groups, but I still regard myself as an environmentalist in that I believe that the natural world should be preserved when it can be shown that such action will also be economically beneficial. My goal is to improve both human welfare and the environment; the current environmental groups claim that they are reducing the impact of humans on the environment. But they are actually making humans and the environment worse off in most of their high profile activities. I do not see how anyone can call himself or herself an “environmentalist” and advocate any of the following goals of many “environmental” organizations:

    o Reducing Earth’s level of atmospheric CO2. As discussed previously, if there is any real danger from the level of CO2 in the atmosphere it is that it is dangerously low. Making CO2 emissions lower increases the risk of CO2 plant starvation during the next ice age, and with it, the food supply for most of the world’s human, animal, plant populations. Those who advocate lowering the atmospheric CO2 levels are really advocating mass starvation of most plants and animals, including humans. I find this absolutely reprehensible, particularly when every climate-related argument for reducing CO2 emissions has been found to be scientifically invalid, including the claim that human activities are increasing atmospheric global warming by increasing atmospheric CO2 levels.

    o Chopping up or frying millions of birds and bats who encounter wind or solar farms. Birds and bats are probably the biggest consumers of insects injurious to humans and other animals. Decimating them by the use of ultra costly wind and solar projects is both unwise and anti-environmental. We need as many birds and bats as we can get, and we need as low a population of injurious insects (which many birds and bats eat) as possible.

    o Preventing the use of DDT, the only economical pesticide with a proven record of preventing malaria but not harming humans or birds, in less developed countries. Outlawing the use of DDT condemned tens of millions to death and hundreds of millions to one of the most debilitating diseases still rampant in the less developed world.

    o Opposing the use of fracking to lower the cost of extracting oil and natural gas. Fracking and associated technology is quite safe and one of the best technologies to increase production of oil and natural gas at a lower cost. It is forcing OPEC to keep prices of these vital fuels lower than they otherwise would be. It does have the disadvantage that fracking for natural gas reduces emissions of CO2 compared to coal, but this is well worth it for providing the advantages of improving human lives by using plentiful, inexpensive gas and oil. There are alleged to be some minor risks, but there are ways to reduce even these rather than banning the use of fracking. Fracking increases human welfare, which is strongly associated with an improved environment.

    o Increasing the cost of using energy to assist humans in their daily tasks by favoring unreliable, intermittent, and more expensive sources. Increasing the cost of using energy by raising its cost will decrease its use and thus human welfare and economic productivity, which are strongly associated with an improved environment as humans turn to such issues as their basic needs are satisfied.

    o Pushing down the reliability of electric power systems. The poster child for this is the State of South Australia, which has now suffered from five state electricity blackouts in the last six months as a result of closing down dependable fossil fuel generating stations in favor of unreliable “renewable” sources.

    o Pushing a very intolerant version of climate alarmism which according to one study has had a cost of roughly $1.5 trillion per year and is based on invalid science. These resources could have been used to really improve human welfare and the environment.

It is long past time for “environmental” groups to do something constructive that will make life on Earth better rather than worse. What they have done in recent years have resulted in all costs and no benefits. They have been taken over by left wing radicals, who are now trying to control the use of energy, which is drastically decreasing human welfare. This hurts humans including lowering their standard of living, which means they will do less to preserve the environment because their basic needs will be less adequately met.

Scientists link California droughts and floods to distinctive atmospheric waves

From NCAR/UCAR:

BOULDER, Colo. — The crippling wintertime droughts that struck California from 2013 to 2015, as well as this year’s unusually wet California winter, appear to be associated with the same phenomenon: a distinctive wave pattern that emerges in the upper atmosphere and circles the globe.

The high- and low-pressure regions of wavenumber-5 set up in different locations during January 2014, when California was enduring a drought, and January 2017, when it was facing floods. The location of the high and low pressure regions (characterized by anticylonic vs. cyclonic upper-level air flow) can act to either suppress or enhance precipitation and storms.

Scientists at the National Center for Atmospheric Research (NCAR) found in a recent study that the persistent high-pressure ridge off the west coast of North America that blocked storms from coming onshore during the winters of 2013-14 and 2014-15 was associated with the wave pattern, which they call wavenumber-5. Follow-up work showed that wavenumber-5 emerged again this winter but with its high- and low-pressure features in a different position, allowing drenching storms from the Pacific to make landfall.

“This wave pattern is a global dynamic system that sometimes makes droughts or floods in California more likely to occur,” said NCAR scientist Haiyan Teng, lead author of the California paper. “As we learn more, this may eventually open a new window to long-term predictability.”

The finding is part of an emerging body of research into the wave pattern that holds the promise of better understanding seasonal weather patterns in California and elsewhere. Another new paper, led by NCAR scientist Grant Branstator, examines the powerful wave pattern in more depth, analyzing the physical processes that help lead to its formation as well as its seasonal variations and how it varies in strength and location.

The California study was published in the Journal of Climate while the comprehensive study into the wave patterns is appearing in the Journal of the Atmospheric Sciences. Both papers were funded by the National Science Foundation, which is NCAR’s sponsor, as well as by the Department of Energy, the National Oceanic and Atmospheric Administration, and NASA.

The new papers follow a 2013 study by Teng and Branstator showing that a pattern related to wavenumber-5 tended to emerge about 15-20 days before major summertime heat waves in the United States.

Strong impacts on local weather systems

Wavenumber-5 consists of five pairs of alternating high- and low-pressure features that encircle the globe about six miles (10 kilometers) above the ground. It is a type of atmospheric phenomenon known as a Rossby wave, a very large-scale planetary wave that can have strong impacts on local weather systems by moving heat and moisture between the tropics and higher latitudes as well as between oceanic and inland areas and by influencing where storms occur.

The slow-moving Rossby waves at times become almost stationary. When they do, the result can be persistent weather patterns that often lead to droughts, floods, and heat waves. Wavenumber-5 often has this stationary quality when it emerges during the northern winter, and, as a result, is associated with a greater likelihood of persistent extreme events.

To determine the degree to which the wave pattern influenced the California drought, Teng and Branstator used three specialized computer models, as well as California rainfall records and 20th century data about global atmospheric circulation patterns. The different windows into the atmosphere and precipitation patterns revealed that the formation of a ridge by the California coast is associated with the emergence of the distinctive wavenumber-5 pattern, which guides rain-producing low-pressure systems so that they travel well north of California.

Over the past winter, as California was lashed by a series of intense storms, wavenumber-5 was also present, the scientists said. But the pattern had shifted over North America, replacing the high-pressure ridge off the coast with a low-pressure trough. The result was that the storms that were forced north during the drought winters were, instead, allowed to make landfall.

Clues to seasonal weather patterns

Forecasters who predict seasonal weather patterns have largely looked to shifting sea surface temperatures in the tropical Pacific, especially changes associated with El Niño and La Niña. But during the dry winters of 2013-14 and 2014-15, those conditions varied markedly: one featured the beginning of an El Niño while the sea surface temperatures during the other were not characteristic of either El Niño or La Niña.

The new research indicates that the wave pattern may provide an additional source of predictability that sometimes may be more important than the impacts of sea surface temperature changes. First, however, scientists need to better understand why and when the wave pattern emerges.

In the paper published in Journal of the Atmospheric Sciences, Branstator and Teng explored the physics of the wave pattern. Using a simplified computer model of the climate system to identify the essential physical processes, the pair found that wavenumber-5 forms when strong jet streams act as wave guides, tightening the otherwise meandering Rossby wave into the signature configuration of five highs and five lows.

“The jets act to focus the energy,” Branstator said. “When the jets are present, the energy is trapped and cannot escape.” But even when the jets are present, the wavenumber-5 pattern does not always form, indicating that other forces requiring study are also at play.

The scientists also searched specifically for what might have caused the wave pattern linked to the severe California drought to form. In the paper published in the Journal of Climate, the pair found that extremely heavy rainfall from December to February in certain regions of the tropical Pacific could double the probability that the extreme ridge associated with wavenumber-5 will form. The reason may have to do with the tropical rain heating parts of the upper atmosphere in such a way that favors the formation of the wavenumber-5 pattern.

But the scientists cautioned that many questions remain.

“We need to search globally for factors that cause this wavenumber-5 behavior,” Teng said, “Our studies are just the beginning of that search.”
