Millions Of Species Going Extinct? Well, Maybe Only 600 ! By Paul Homewood It was not long ago that we were bombarded with ludicrous claims that a million species were threatened “by humans”.
A new study puts all of this into perspective: Almost 600 plant species have been lost from the wild in the last 250 years, according to a comprehensive study. The number is based on actual extinctions rather than estimates, and is twice that of all bird, mammal and amphibian extinctions combined. Scientists say plant extinction is occurring up to 500 times faster than what would be expected naturally. In May, a UN report estimated that one million animal and plant species were threatened with extinction. Recent Studies Indicate Species Extinctions Decline With Warming – Mass Extinction Events Due To COOLING. By Kenneth Richard on 16.
May 2019 During the last few hundred years, species extinctions primarily occurred due to habitat loss and predator introduction on islands. Extinctions have not been linked to a warming climate or higher CO2 levels. In fact, since the 1870s, species extinction rates have been plummeting. Image Sources: Loehle & Eschenbach (2012), BBC, Wrightstone, 2019 In the past it has been widely reported that high and abruptly changing CO2 concentrations led to climate conditions that were “too hot for complex life to survive” on the planet.
Anxious About Extinctions? Go Check The Facts! Mass extinction lie exposed: life is thriving. Gregory Wrightstone: exposing the mass extinction lie. Summary: The latest chapter of the climate campaign consists of warnings about a coming mass extinction of species.
Here is a stunning analysis of these claims by Gregory Wrightstone. This made a big impact at Wednesday’s House hearings. The UN's species extinction fraud. Earth Day 2019: The sixth mass extinction and the imperative of apocalypse. Having celebrated Earth Day and warned of various dimensions of environmental collapse since 1970, are there any circumstances even barely conceivable under which the environmental left would say that no more Earth Days are needed?
By Benjamin Zycher Earth Day—Lenin’s birthday—stands for the proposition that environmental crises both immediate and looming are eternal, with mankind always the central cause, and that the unbroken record of failure of Earth Day doom and gloompredictions for almost five decades actually should be a source of pride.
In short, in terms of its endless predictions of apocalypse, the environmental left truly believes—indeed, it is driven to believe, it must believe, it cannot believe otherwise—that an invincible record of past failure is irrelevant with respect to future performance, a point to which we return below. It gets worse or, rather, better: Wow. Let us delve briefly into what we do know. Another dodgy Earth Day ploy hyping flawed and failed “species extinction” propaganda. Guest essay by Larry Hamlin The latest 2019 Earth Day event, the 50th since the first such propaganda event started in 1970, has the proclaimed theme of “Protect Our Species” and offers the usual and often repeated litany of species mass extinction alarmist exaggeration including: “human beings have irrevocably upset the balance of nature and, as a result, the world is facing the greatest rate of extinction since we lost the dinosaurs more than 60 million years ago.
Biodiversity and land sparing. Why are lions decreasing, wolves increasing and tigers holding steady?
My article for Reaction on biodiversity: Driven perhaps by envy at the attention that climate change is getting, and ambition to set up a great new intergovernmental body that can fly scientists to mega-conferences, biologists have gone into overdrive on the subject of biodiversity this week. They are right that there is a lot wrong with the world’s wildlife, that we can do much more to conserve, enhance and recover it, but much of the coverage in the media, and many of the pronouncements of Sir Bob Watson, chair of the Intergovernmental Panel on Biodiversity and Ecosystem Services (IPBES), are frankly weird. The threat to biodiversity is not new, not necessarily accelerating, mostly not caused by economic growth or prosperity, nor by climate change, and won’t be reversed by retreating into organic self-sufficiency. Here’s a few gentle correctives. The Extinction Rebellion’s hysteria vs. climate science. Summary: The Extinction Rebellion and the Green New Deal arouse fears of extinction for other species, and humanity.
Only the complicit silence of climate scientists makes this possible. Compare the alarmists’ claims with what scientists said in the IPCC’s Fifth Assessment Report (AR5). Too bad that journalists don’t. Climate hysteria goes mainstream. Climate scientists are silent. Nature crisis: Humans ‘threaten 1m species with extinction’-BBC. By Paul Homewood h/t Robin Guenier Jaime Jessop responds to the latest UN report on bio-diversity:
UN’s Extinction Warning Does Not ADD Up. The Truth About The Latest Mass Extinction Scare. Global Warming off the hook? Alien species are primary cause of recent global extinctions. Alien species are primary cause of recent global extinctions Alien species are the main driver of recent extinctions in both animals and plants, according to a new study by UCL researchers.
University College London They found that since 1500, alien species have been solely responsible for 126 extinctions, 13% of the total number studied. The Extinction of Honest Science. With no significant warming for 20 years, the climate alarmists need better scares.
The temperature rise of about 0.8 degC in more than 100 years is not only non-scary, it’s been immensely beneficial for feeding the globe’s burgeoning population. Now the “extreme weather” furphy is at work, with any storm or flood attributed by Al Gore and the Climate Council to fossil fuel emissions. There’s the purported “ocean acidification” but I’m yet to see evidence that it has hurt a solitary crab, let alone a species. As for sea-level rises, well, check my birthplace, Fremantle, butting the Indian Ocean: its tide gauge shows 12 cms rise in the past 120 years – compare that with 20cm for the length of my hand.
An Example of AR4 WG2 False Alarmism (Extinction) By Rud Istvan, This post is a lightly reworked last third of much longer essay No Bodies in ebook Blowing Smoke, foreword by Professor Judith Curry of Georgia Tech. It concerns the demonstrably misleading dishonesty of AR4 WG2 concerning climate change caused species extinctions, and the shoddy science behind the one paper AR4 ultimately relied upon. It is a saga not yet told at WUWT, which Charles the Moderator thought might be interesting since actually very science based in a perverse way. One of the firmer catastrophic anthropogenic global warming (CAGW) predictions made by IPCC AR4 WG2 was an alarming increase in species extinctions. §4.4.11 Global synthesis including impacts on biodiversity was fairly specific. If warming reached 3°C above pre-industrial levels (projected absent serious mitigation) 21-52% of all species were committed to extinction (not necessarily yet extinct) by 2100.
The Breakthrough Institute - Welcome to the Narcisscene. Global Extinction Rates: Why Do Estimates Vary So Wildly? Most ecologists believe that we are in the midst of the sixth mass extinction. Humanity’s impact on nature, they say, is now comparable to the five previous catastrophic events over the past 600 million years, during which up to 95 percent of the planet’s species disappeared. We may very well be. But recent studies have cited extinction rates that are extremely fuzzy and vary wildly. The Millennium Ecosystem Assessment, which involved more than a thousand experts, estimated an extinction rate that was later calculated at up to 8,700 species a year, or 24 a day.
More recently, scientists at the U.N. The golden toad, once abundant in parts of Costa Rica, was declared extinct in 2007. But nobody knows whether such estimates are anywhere close to reality. Nor is there much documented evidence of accelerating loss. Moreover, the majority of documented extinctions have been on small islands, where species with small gene pools have usually succumbed to human hunters. He is not alone. About the mass extinctions supposedly occurring now - Fabius Maximus website. Summary: More fears fed by activists.
As the papers cited below show, they have little support from science – but are seldom rebuked by scientists. Each round of such exaggerated claims erodes away the public’s trust. The leaders of science institutions show little interest in fixing this problem. We cannot afford to have science’s credibility squandered for short-term political gains. The Sky is Falling! New paper from Loehle & Eschenbach shows extinction data has been wrongly blamed on climate change due to island species sensitivity. One of the most famous extinctions -The Dodo, a flightless bird endemic to the Indian Ocean island of Mauritius – Image via Wikipedia Guest post by Dr. Craig Loehle Last year, Willis Eschenbach had a WUWT post about extinction rates being exaggerated in the literature. I offered to help him get this published, and it is now out. The Latest Climate Scare: Mass Die-Offs. How many animals are really going extinct?
A century ago this fall, the world’s last passenger pigeon, a bird named Martha, died at the Cincinnati Zoo. Her death marked the end of an astonishing decline in that bird’s numbers; in America’s first centuries, passenger pigeons were so abundant that stories about them can be almost impossible to believe. Cotton Mather described a flock a mile wide that took hours to pass overhead, and John James Audubon reported that they blocked out the sun like an eclipse.
By 1900, thanks to deforestation and overhunting, passenger pigeons had disappeared from the wild. Baseless claim from WWF: Half of global wildlife lost, says new WWF report. Are 30 thousand species going extinct every year? Summary: The warnings become increasingly dire and shrill as we approach November’s United Nations Climate Change Conference in Paris. One theme warns about the increasing rate of extinctions, described with astonishing numbers — and projected to add humanity to the endangered species list. IPCC’s species extinction hype “fundamentally flawed” Before you read this, I’ll remind WUWT readers of this essay: Extinctions and shutting down the Gulf Stream. By Andy May. Species Extinction Rate Plummets Whopping 96% During Warming, Elevated CO2. By Kenneth Richard Last month, National Geographic and other news organizations ran the disheartening headline “First Mammal Species Goes Extinct Due to Climate Change“1. Study: high CO2 levels equated to “warm average temperatures and flourishing life” low CO2, “preceding an ice age and eventual mass extinction”
From the UNIVERSITY OF MISSOURI-COLUMBIA: Paleoclimate researchers find connection between carbon cycles, climate trendsCarbon cycling research can help scientists predict global warming and cooling trends COLUMBIA, Mo. – Making predictions about climate variability often means looking to the past to find trends. Fabricating Climate Doom – Part 3: Extreme Weather Extinctions Enron Style. Guest essay by Jim Steele, Director emeritus Sierra Nevada Field Campus, San Francisco State University. IPCC admission from new report: ‘no evidence climate change has led to even a single species becoming extinct’ In 2007, the IPCC predicted that rising global temperatures would kill off many species. But in its new report, part of which will be presented next Monday, the UN climate change body backtracks. There is a shortage of evidence, a draft version claims. Climate Change and Extinction: What Is Natural?
Guest opinion by Dr. Tim Ball | Proponents of the anthropogenic global warming (AGW) hypothesis successfully, but inaccurately, present natural events as unnatural. It works, because most don’t know what is natural. False Alarm: Debunked Climate Paper Triggers Apocalyptic Scare-Mongering. Causes of the Quaternary Megafauna l Extinction Event by Marianne Lehnert.
