Guest essay by Dr. Patrick J. Michaels It’s hard to say how many punny posts we came up with using those words when Carol Browner was Bill Clinton’s EPA Administrator, but here we use it in the context of a recent Science paper by J-F.
‘Carbon dioxide and global warming changed that’
Testifying before Congress, former UN climate scientist Dr. Patrick Michaels says increased carbon dioxide concentrations in the atmosphere are causing a ‘remarkable greening of planet Earth’. Michaels says previous government calculations of the “Social Cost of Carbon” erroneously ignore the substantial benefits of increased CO2.
DR MICHAELS: “There is another systematic error in the previous calculations of the SCC [Social Cost of Carbon]. We live on a planet that is becoming greener because of the direct physiological effects of increasing carbon dioxide on plant photosynthesis. A massive survey of the scientific literature by Dr. Craig Idso shows this caused a $3.2 trillion increment in agricultural output from 1961 to 2011.”

In eastern Tibetan forest, signs of tree growth amid climate change
Researchers follow a lead from nomadic herders and find a forest getting nutrients and water from thawing permafrost

- Word of mouth from nomadic herders led Lucas Silva into Tibetan forests and grasslands. What his team found was startling: rapid forest growth in tune with what scientists had been expecting from climatic changes triggered by rising levels of carbon dioxide.
On the eastern Tibetan Plateau — in an area where it was thought that “climatically induced ecological thresholds had not yet been crossed” — Silva’s team found that the increasing availability of soil nutrients and water from thawing permafrost is stimulating the chemistry of the wood in a species of fir trees (Abies faxoniana).
“Our results confirmed the reports of local herders and showed a recent increase in tree growth that has been unprecedented since the year 1760,” Silva said. “These result demonstrate that under a specific set of conditions, forests can respond positively to human-induced changes in climate.”
The findings were published Aug. 31 in Science Advances, an online, open-access publication of the American Association for the Advancement of Science.
Nomads had reported their observations to study co-author Geng Sun of China’s Chengdu Institute of Biology in Sichuan, China. The research team traveled to the region in eastern Tibet where they found old-growth forests, smaller patches of trees and trees isolated on the perimeter of the forests.
“We wanted to take a long term view of changes in tree growth across this gradient,” Silva said. “To do so, we combined tree-ring measurements with laboratory analyses to look for changes in growth as well as chemical signals of climatic change.”…
Guns and Tractors Threaten Biodiversity More Than Global Warming
Finally … and so blindingly obvious to those not blinded by the AGW propaganda. The main driver of wildlife extinction is not climate change, but humanity’s harvesting of species and our ever-expanding agricultural footprint. This is according to a new study of nearly 9,000 ‘threatened’ or ‘near-threatened’ species. While scientists acknowledge climate change is a threat, they found that three-quarters are being over-exploited for commerce, recreation or subsistence. Demand for meat and body parts, for example, have driven the Western gorilla and Chinese pangolin to near extinction, and pushed the Sumatran rhinoceros – prized in China for bogus medicines made from its horn – over the edge. And more than half of the 8,688 species of animals and plants evaluated are suffering due to the conversion of their natural habitats into industrial farms and plantations, mainly to raise livestock and grow commodity crops for fuel or food. By comparison, only 19 per cent of these species are currently affected by climate change, they reported in a study published in the peer-reviewed journal Nature. Conservation budgets, the researchers argued, must reflect this reality. And then some of the usual BS ‘There is no need to see tradeoffs among different conservation priorities – we need them all,’ Peter MacIntyre, an expert on the ecology of fresh-water systems at the University of Wisconsin, told AFP. Translation: The AGW cult wants all the money.

‘Selfish vegans are ruining the environment’ – ‘Vegan diet wastes available land that could otherwise feed more people’
. “When applied to an entire global population, the vegan diet wastes available land that could otherwise feed more people,”
If you’ve ever suspected nothing is more annoying than prissy, sanctimonious vegans, it turns out you have company: Nature wants to punch them in the face, too.
As is often the case with virtue-signaling lifestyles, number-crunching doesn’t quite justify the supposed benefits of granola-crunching. “When applied to an entire global population, the vegan diet wastes available land that could otherwise feed more people,” concluded news site Quartz in a review of a scientific study published in the journal Elementa that compares the sustainability of various eating patterns.
Just as global-warming hysteria leads to draconian restrictions and taxes that devastate the poor in order to provide conscience relief to progressives, totalitarian eating habits aren’t as sustainable as more moderate ones. For instance, trying to grow crops on land best suited for use as grazing land for cattle means wasting resources.
Considering 10 different kinds of diet patterns, the study concluded that veganism rated only in the middle of the pack, as the fifth-most sustainable. Two kinds of omnivore scenarios did better, as did “dairy-friendly vegetarian,” which came in first, and “egg-and-dairy-friendly vegetarian,” which placed second.
As for the omnivores, the highest-rated (third overall) in terms of sustainability was the scenario in which nobody is a vegetarian, but everybody cuts back on meat modestly (13 percent). Red meat, poultry and fish would continue to be the leading protein sources, as they are now.…
CAMP NELSON, Calif. (AP) — At the foot of a giant sequoia in California’s Sierra Nevada, two arborists stepped into harnesses then inched up ropes more than 20 stories into the dizzying canopy of a tree that survived thousands of years, enduring drought, wildfire and disease.
There, the arborists clipped off tips of young branches to be hand-delivered across the country, cloned in a lab and eventually planted in a forest in some other part of the world.
The two are part of a cadre of modern day Johnny Appleseeds who believe California’s giant sequoias and coastal redwoods are blessed with some of the heartiest genetics of any trees on Earth – and that propagating them will help reverse climate change, at least in a small way.
“It’s a biological miracle,” said tree climber Jim Clark, firmly back on the ground and holding a green sprig to his lips as if to kiss it. “This piece of tissue … can be rooted, and we have a miniature 3,000-year-old…
The surprising discovery that plants may be responsible for up to 30 per cent of the world’s methane, a powerful greenhouse gas, is no reason to stop planting forests, a scientist has warned. A team led by Frank Keppler, of Max Planck Institute for Nuclear Physics in Germany, found that living plants emit 10 to 1000 times more of the gas than decaying matter. And plants increase their methane emissions when warmed by the sun, it was found. Plants have long been seen as weapons against global warming because they absorb another greenhouse gas, carbon dioxide. It’s a surprise, said David Etheridge of the CSIRO’s Marine and Atmospheric Research division. “You think you know everything.” Sydney Morning Herald, 13 Jan 2006

‘Going solar isn’t green if you cut down tons of trees’: Six Flags ‘to level 66 acres of trees’ to make room for solar panels
It’s music to an environmentalist’s ears: Six Flags Great Adventure wants to power its park with solar energy by installing a solar panel farm on a portion of the 134 acres of land it owns in Jackson, New Jersey. But as the company spells out its plan, the needle scratches across the record: To make room for the panels, it plans to level 66 acres of trees.
The plan, the largest solar installation in New Jersey, will generate 21.4 megawatts of electricity, enough to power the amusement park’s Garden State facility. The company projects that the initiative will eliminate approximately 215,000 tons of CO2emissions over 15 years, a result that it says more than compensates for the loss of trees.
“We are excited about the fact that this project will reduce carbon emissions by 31 times more than the trees and shrubs that will be removed, and that we will become the world’s first solar-powered theme park,” said Kristin Siebeneicher, communications manager for Six Flags Great Adventure and Safari. She added, “This project is a positive for the environment and will not harm the habitats of threatened or endangered species, nor impair protected wetlands or watersheds.” (Six Flags says that at the moment, it does not plan to carry out similar projects at its other parks.)
Those opposed to the project say if Six Flags really wanted an environmentally friendly project, it would have placed the lion’s share of the solar panels on one of its parking lots, creating so-called canopies—structures with panels placed
