Environmentalists Trash Science 7 Enviro Predictions From Earth Day 1970 That Were Just Dead Wrong Photo of Andrew Follett




Environmentalists truly believed and predicted during the first Earth Day in 1970 that the planet was doomed unless drastic actions were taken.
Humanity never quite got around to that drastic action, but environmentalists still recall the first Earth Day fondly and hold many of the predictions in high regard.
So this Earth Day, The Daily Caller News Foundation takes a look at predictions made by environmentalists around the original Earth Day in 1970 to see how they’ve held up.
Have any of these dire predictions come true? No, but that hasn’t stopped environmentalists from worrying.


From predicting the end of civilization to classic worries about peak oil, here are seven environmentalist predictions that were just flat out wrong.
1: “Civilization Will End Within 15 Or 30 Years”
Harvard biologist Dr. George Wald warned shortly before the first Earth Day in 1970 that civilization would soon end “unless immediate action is taken against problems facing mankind.” Three years before his projection, Wald was awarded the Nobel Prize for Physiology or Medicine.
Wald was a vocal opponent of the Vietnam War and the nuclear arms race. He even flew to Moscow at one point to advise the leader of the Soviet Union on environmental policy.
Despite his assistance to a communist government, civilization still exists. The percentage of Americans who are concerned about environmental threats has fallen as civilization failed to end by environmental catastrophe.
2: “100-200 Million People Per Year Will Be Starving To Death During The Next Ten Years”
Stanford professor Dr. Paul Ehrlich declared in April 1970 that mass starvation was imminent. His dire predictions failed to materialize as the number of people living in poverty has significantly declined and the amount of food per person has steadily increased, despite population growth. The world’s Gross Domestic Product per person has immeasurably grown despite increases in population.
Ehrlich is largely responsible for this view, having co-published “The Population Bomb” with The Sierra Club in 1968. The book made a number of claims including that millions of humans would starve to death in the 1970s and 1980s, mass famines would sweep England leading to the country’s demise, and that ecological destruction would devastate the planet causing the collapse of civilization.
3: “Population Will Inevitably And Completely Outstrip Whatever Small Increases In Food Supplies We Make”
Paul Ehrlich also made the above claim in 1970, shortly before an agricultural revolution that caused the world’s food supply to rapidly increase.
Ehrlich has consistently failed to revise his predictions when confronted with the fact that they did not occur, stating in 2009 that “perhaps the most serious flaw in The Bomb was that it was much too optimistic about the future.”
4: “Demographers Agree Almost Unanimously … Thirty Years From Now, The Entire World … Will Be In Famine”
Environmentalists in 1970 truly believed in a scientific consensus predicting global famine due to population growth in the developing world, especially in India.
“Demographers agree almost unanimously on the following grim timetable: by 1975 widespread famines will begin in India; these will spread by 1990 to include all of India, Pakistan, China and the Near East, Africa. By the year 2000, or conceivably sooner, South and Central America will exist under famine conditions,” Peter Gunter, a professor at North Texas State University, said in a 1970 issue of The Living Wilderness.”By the year 2000, thirty years from now, the entire world, with the exception of Western Europe, North America, and Australia, will be in famine.”
India, where the famines were supposed to begin, recently became one of the world’s largest exporters of agricultural products and food supply per person in the country has drastically increased in recent years. In fact, the number of people in every country listed by Gunter has risen dramatically since 1970.
5: “In A Decade, Urban Dwellers Will Have To Wear Gas Masks To Survive Air Pollution”
Life magazine stated in January 1970 that scientist had “solid experimental and theoretical evidence” to believe that “in a decade, urban dwellers will have to wear gas masks to survive air pollution…by 1985 air pollution will have reduced the amount of sunlight reaching Earth by one half.”
Despite the prediction, air quality has been improving worldwide, according to the World Health Organization. Air pollution has also sharply declined in industrialized countries. Carbon dioxide (CO2), the gas environmentalists are worried about today, is odorless, invisible and harmless to humans in normal amounts.
6: “Childbearing [Will Be] A Punishable Crime Against Society, Unless The Parents Hold A Government License”
David Brower, the first executive director of The Sierra Club made the above claim and went on to say that “[a]ll potential parents [should be] required to use contraceptive chemicals, the government issuing antidotes to citizens chosen for childbearing.” Brower was also essential in founding Friends of the Earth and the League Of Conservation Voters and much of the modern environmental movement.
Brower believed that most environmental problems were ultimately attributable to new technology that allowed humans to pass natural limits on population size. He famously stated before his death in 2000 that “all technology should be assumed guilty until proven innocent” and repeatedly advocated for mandatory birth control.
Today, the only major government to ever get close to his vision has been China, which ended its one-child policy last October.
7: “By The Year 2000 … There Won’t Be Any More Crude Oil”
On Earth Day in 1970 ecologist Kenneth Watt famously predicted that the world would run out of oil saying, “You’ll drive up to the pump and say, ‘Fill ‘er up, buddy,’ and he’ll say, ‘I am very sorry, there isn’t any.’”


Numerous academics like Watt predicted that American oil production peaked in 1970 and would gradually decline, likely causing a global economic meltdown. However, the successful application of massive hydraulic fracturing, or fracking, caused American oil production to come roaring back and there is currently too much oil on the market.

American oil and natural gas reserves are at their highest levels since 1972 and American oil production in 2014 was 80 percent higher than in 2008 thanks to fracking.
Furthermore, the U.S. now controls the world’s largest untapped oil reserve, the Green River Formation in Colorado. This formation alone contains up to 3 trillion barrels of untapped oil shale, half of which may be recoverable. That’s five and a half times the proven reserves of Saudi Arabia. This single geologic formation could contain more oil than the rest of the world’s proven reserves combined.

Study: Global Warming Has Improved U.S. weather? Obama Global Warming/: Climate Change is the Greatest Threat? What?

 






The media release is below.
###
Recent warmer winters may be cooling climate change concern
NEW YORK UNIVERSITY
The vast majority of Americans have experienced more favorable weather conditions over the past 40 years, researchers from New York University and Duke University have found. The trend is projected to reverse over the course of the coming century, but that shift may come too late to spur demands for policy responses to address climate change.
The analysis, published in the journal Nature, found that 80 percent of Americans live in counties where the weather is more pleasant than four decades ago. Winter temperatures have risen substantially throughout the United States since the 1970s, but summers have not become markedly more uncomfortable. The result is that weather has shifted toward a temperate year-round climate that Americans have been demonstrated to prefer.
“Rising temperatures are ominous symptoms of global climate change, but Americans are experiencing them at times of the year when warmer days are welcomed,” explains Patrick J. Egan, an associate professor in NYU’s Wilf Family Department of Politics who authored the study with Duke’s Megan Mullin.
However, he and Mullin, an associate professor at Duke’s Nicholas School of the Environment, discovered a looming shift in these patterns when they used long-term projections of temperature changes to evaluate future weather Americans are likely to experience. According to these estimates, nearly 90 percent of the U.S. public may experience weather at the end of the 21st century that is less preferable than weather in the recent past.
“Weather patterns in recent decades have been a poor source of motivation for Americans to demand policies to combat the climate change problem,” observes Mullin. “But without serious efforts to reduce greenhouse gas emissions, year-round climates ultimately will become much less pleasant.”
In a 2012 study, the duo found that local weather temporarily influences people’s beliefs about evidence for global warming. That research, which appeared in the Journal of Politics, found that those living in places experiencing warmer-than-normal temperatures at the time they were surveyed were significantly more likely than others to say there is evidence for global warming.
In the Nature study, Egan and Mullin took a broader approach to understanding weather patterns–and how Americans experience them. The researchers analyzed 40 years of daily weather data (from 1974 through 2013) on a county-by-county basis to evaluate how the population’s experience with weather changed during this period, which is when climate change first emerged as a public issue.

They found that Americans on average have experienced a steep rise in January maximum temperatures–an increase of 1.04 °F per decade (0.58 °C). By contrast, daily maximum temperatures in July rose by only 0.13 °F per decade (0.07 °C). Moreover, humidity in the summer has declined somewhat since the mid-1990s. In other words, winter temperatures have become warmer for virtually all Americans while summer conditions have remained relatively constant.

To quantify how Americans are evaluating these changes, Egan and Mullin drew upon research by economists examining weather’s role in growth of the Sun Belt and population declines in the Northeast and Midwest. Using these findings, they developed a metric of the average American’s preferences about weather. This “weather preference index” (WPI) reflects the U.S. public’s preferences for places with warmer temperatures in winter and cooler temperatures and lower humidity in summer. The index also takes into account preferences about precipitation. Egan and Mullin found that WPI scores have risen in counties accounting for 80 percent of the U.S. population since the 1970s.

But projections of future temperatures–and future WPI scores–offer a markedly different picture. Climate change models predict that under all potential levels of future warming, average summer temperatures will ultimately rise at a faster rate than winter temperatures. Using these projections, the researchers calculated that under a severe warming scenario, WPI scores will decline such that an estimated 88 percent of the U.S. public will experience less pleasant weather at the end of this century than it has in the past 40 years.

Claim: Gradual Decline Of Dinosaurs Before Extinction, Mass Extinction Of Dinosaurs Thought To Have Been Triggered By An Asteroid ? Or Was It The Flood? As Found In Genesis 6 That The Question Here?

So The Question IS Ask Here , If You believe that  Dinosaurs were all kill  Asteroid ? OR You Believe Dinosaurs were all kill in the flood. It,s not that hard.

 

 

Was Noah’s Flood Global?

Did Noah experience a local flood which left only a few sediment layers, as floods do today? God’s record is clear: the water covered the entire globe and killed all the animals on earth. Such unique conditions are the only way to explain worldwide fossil-bearing layers thousands of feet deep.

Local Floods Help Us Understand Noah’s Flood Geology

Geologists repeatedly discover the catastrophic effects of local flooding on the earth’s surface, resulting in the same conclusion each time: that substantial amounts of water can have the same geological effect in a short period of time (even laying down rock layers) that hypothesized millions of years of slow water flow would have.

Noah Did More than Build an Ark

Like people today, almost certainly the people of Noah’s day were busy enjoying the pleasures of life and did not believe or care that judgment was coming. In 2 Peter 2:5, Noah is described as a “preacher of righteousness.”

Psalm 104 and the Flood

Psalm 104:6–9 sheds important additional light on the geological effects of the Flood. “The mountains rose, the valleys sank down to the place which You established for them” (vs. 8).

Liberal Trash Science.,Claim: Ground-level artificial lights disrupt bird migration, You Think Before They Put This Out They Have Again Ask Bird Watching Group's First?

###
CENTRAL ORNITHOLOGY PUBLICATION OFFICE
It’s not just lights on skyscrapers that can impact migrating birds–new research in The Condor: Ornithological Applications demonstrates that even ground-level artificial lights can affect birds passing overhead at night.
Most birds migrate at night, and artificial light disrupts migrations in a variety of ways, throwing off birds’ natural navigation abilities and even attracting them to fatal collisions with buildings. The bulk of the research on how lights affect birds has been focused on lights on tall structures like skyscrapers and cell towers, but most artificial lights are actually near ground level–street lights, porch lights, and car headlights, to name just a few.
Matt Watson, David Wilson, and Daniel Mennill of the University of Windsor recorded the flight calls of migrating birds passing overhead during the 2013 fall migration in southern Ontario, Canada, comparing sites with and without ground-level artificial lights. Analyzing 352 hours of recordings, including the calls of at least 15 bird species, they found that significantly more flight calls were recorded at lit sites than at dark sites. “By pointing microphones at the night sky, we can survey migratory birds based on the quiet sounds they produce in flight,” says Mennill. “This simple technique offers a special opportunity because we can resolve particular species of birds, or groups of species, using a fairly simple technology.”
“It was exciting to find that even low-level anthropogenic lights affect call detections from migrating birds,” adds Watson. Their findings have several possible explanations–ground-level lights could be disorienting birds, causing them to call more often and decrease their altitude as they attempt to straighten themselves out, or they could actually be attracting additional birds, as has already been documented with higher-elevation lights. In either case, artificial lights are causing migrating birds to waste energy, which could affect their chances of surviving their journey.
This study underscores importance of studying the consequences for wildlife when human activities alter the natural environment. “Anthropogenic light has profound effects on wild animals. For migratory birds, we know that lights on top of skyscrapers, communication towers, and lighthouses disorient and attract birds,” says Mennill. “Our study reveals for the first time that even low-intensity lights on the ground influence the behavior of migratory birds overhead.”

Emails reveal NY AG Schneiderman. other AG’s colluding with Al Gore and greens to investigate climate skeptics








Washington, D.C. (April 15, 2016) – The offices of New York Attorney General Eric Schneiderman (D), and other politically-aligned AGs, secretly teamed up with anti-fossil fuel activists in their investigations against groups whose political speech challenged the global warming policy agenda, according to e-mails obtained by the Energy & Environment Legal Institute (E&E Legal).
E&E Legal released these emails on the heels of a Wall Street Journal report about a January meeting, in which groups funded by the anti-fossil fuel Rockefeller interests met to urge just this sort of government investigation and litigation against their political opponents. After the Competitive Enterprise Institute (CEI) criticized these AGs’ intimidation campaign, the U.S. Virgin Islands’ Claude Earl Walker — one of the AGs working with Schneiderman — subpoenaed ten years of CEI records relating to the global warming issue.
The e-mail correspondence between Schneiderman’s staff, the offices of several state attorneys general, and activists was obtained under Vermont’s Public Records Law, and also show Schneiderman’s office tried to obscure the involvement of outside activists. His top environmental lawyer encouraged one green group lawyer who briefed the AGs before their March 29 “publicity stunt” press conference with former U.S. Vice President Al Gore not to tell the press about the coordination. At that event the AGs announced they were teaming up to target opponents of the global warming agenda.
David Schnare, E&E Legal’s General Counsel, noted, “These emails show Schneiderman’s office suggested their outside-activist green allies deceive the press; meanwhile, AGs in his coalition have subpoenaed at least one policy group’s correspondence with the media. We call on these AGs to immediately halt their investigation and lay out for the public the full extent of this collusion, producing all records or information provided them in briefings or other work with the outside activists, including those they are trying to keep secret through a Common Interest Agreement.”
The latter point references the New York and Vermont AGs trying to claim privilege for discussions and emails even with outside groups in this effort to go after shared political opponents, including each state that receives an open records request immediately alerting the rest to that fact. In that case, according to the Schneiderman office’s draft, every state was to immediately return any records to New York. To its credit Vermont objected to that as, naturally, being against state laws.
The documents cover the weeks leading up to that aforementioned press conference with numerous AGs, led by Schneiderman and Gore. They show communication and coordination between:
Lem Srolovic, chief of the New York Attorney General’s Environmental Protection Bureau
Scot Kline, a Vermont assistant attorney general
Matt Pawa, an environmental lawyer who works with the Climate Accountability Institute and the
Global Warming Legal Action Project of the Civil Society Institute
Peter Frumhoff, director of science and policy for the Union of Concerned Scientists
Pawa and Frumhoff have been pushing for this investigation for years, at least since a 2012 workshop titled “Establishing Accountability for Climate Change Denial,” a brainstorming session in California for activists on convincing attorneys general to investigate “deniers” through the Racketeer Influenced and Corrupt Organizations Act (RICO).
“These emails strongly suggest the financial motive for AGs to pursue their political opponents, not content with merely silencing and scaring away support for those who dare disagree with their extreme global warming agenda,” said Craig Richardson, E&E Legal’s Executive Director. “Alarmingly, government officials are actively trying to cover up their coordination by using a Common Interest Agreement, even to claw back records already circulated, which another attorney general properly objected to as violating state law.”
Emails recently obtained by CEI also show academics aspiring to “convince state AGs to file suit” under RICO laws, also plainly with an eye toward obtaining a massive settlement to underwrite the global warming campaign. CEI awaits a ruling by a Virginia court on other related correspondence that should prove highly relevant to these AGs’ campaign.
As the Vermont and New York correspondence show, Pawa and Frumhoff were invited to secretly brief the state attorneys general. They each received 45 minutes to provide arguments on “climate change litigation” and “the imperative of taking action now” immediately prior to the AGs’ press conference, according to schedules prepared by Schneiderman’s office.
The next day, March 30, Pawa wrote to Srolovic of New York and Kline seeking help. A Wall Street Journal reporter wanted to talk to Pawa, and he asked the two officials: “What should I say if she asks if I attended?”
Srolovic of the New York State Attorney General’s office replied: “My ask is if you speak to the reporter, to not confirm that you attended or otherwise discuss the event.”
The documents obtained by E&E Legal also include responses to a questionnaire sent to the state attorneys general by the New York AG’s office. The US Virgin Islands Attorney General noted he had just completed an $800 million settlement from Hess Oil company — used to create an “environmental response trust” and promote solar power — and was interested in using this coalition to identify “other potential litigation targets” and ways to “increase our leverage”.
AGs across the country have criticized these investigations, calling them efforts to “silence critics”
Attorneys General across the country have come out strongly against these investigations. West Virginia AG Patrick Morrisey said, “You cannot use the power of the office of the Attorney General to silence your critics.” Oklahoma AG Scott Pruitt and Alabama AG Luther Strange issued a joint press release stating, “It is inappropriate for State Attorneys General to use the power of their office to attempt to silence core political speech on one of the major policy debates of our time.” AG Jeff Landry of Louisiana said, “It is one thing to use the legal system to pursue public policy outcomes; but it is quite another to use prosecutorial weapons to intimidate critics, silence free speech, or chill the robust exchange of ideas.”
Following are the actual e-mails E&E Legal received through it’s open records request:
Work groups and first call set
Vermont OGA cover letter
Vermont OAG intended authorities
Vermont & New York OAGs fine with Sharon Eubanks joining Pawa for AGs briefing
Questionnaire responses
New York OAG wants to call Vermont OAG w something learned
New York OAG wants Pawa to not confirm participation to WSJ
Gore is adding star power and words to avoid
Development of Agenda
Common Interest Agreement and discussion
Calls with Pawa and Frumhoff
Call agenda
AG’s principles
The Energy & Environment Legal Institute (E&E Legal) is a 501(c)(3) organization engaged in strategic litigation, policy research, and public education on important energy and environmental issues. Primarily through its petition litigation and transparency practice areas, E&E Legal seeks to correct onerous federal and state policies that hinder the economy, increase the cost of energy, eliminate jobs, and do little or nothing to improve the environment.

More Liberal Trash Science, Claim: Twentieth century warming allowed moose to colonize the Alaskan tundra

“The average shrub height in 1860 is only an estimate, which is a limitation of the study.” Not science. An unverifiable hypothesis.
The media release is below.

Twentieth century warming allowed moose to colonize the Alaskan tundra
Warming increased shrub availability for foraging, allowed moose to colonize hundreds of miles of tundra
PLOS
The establishment of moose in tundra regions of Alaska was the result of warmer and longer summers that increased their shrub habitat, according to a study published April 13, 2016 in the open-access journal PLOS ONE by Ken Tape from the University of Alaska, USA, and colleagues.
Moose, an iconic wildlife presence throughout Alaska, were actually absent from its tundra regions earlier in the 20th century. It was previously speculated that overhunting was responsible for this absence.
In the tundra landscape characterized by very short plants, moose must forage on shrubs sticking up above the snow during winter to survive. The authors of the present study therefore wanted to investigate whether a lack of available shrub vegetation was an alternative explanation for the previous absence of moose in the tundra. They used recent changes in shrub cover and relationships between shrub height and summer temperature to estimate the available moose habitat in Arctic Alaska around 1860, to compare it to that available in 2009.
The researchers estimated that average shrub height has increased since 1860 from around 1.1m to around 2m, greatly increasing the available forage sticking up above the snow. They therefore suggest that shrubs prior to the 20th century were too short and sparse in the tundra to support moose. They posit that as shrub habitat has increased as a result of twentieth century warming extending the summer growing season, moose have moved northward into tundra regions.
The average shrub height in 1860 is only an estimate, which is a limitation of the study. Nonetheless, the study provides evidence that shrub availability may explain the 20th century colonization of the tundra by moose. The authors suggest that the northward shift of moose in Alaska by hundreds of miles may be one of the most dramatic wildlife changes linked to climate change.
Ken Tape notes, “Although scientists have been anticipating changes to wildlife in response to the observed changes climate and vegetation of the Arctic, this is one of the first studies to demonstrate it. We showed that the large-scale northward shift of moose was likely in response to their increasing shrub habitat in the tundra.”

Claim: Decrease in air pollution associated with decrease in respiratory symptoms among children False. Since air quality is not associated with childhood asthma in the first place.

 



 The media release is below.


One of the most important things you can do to manage your asthma is to work with your healthcare provider to identify and minimize your exposure to your asthma triggers.

Triggers are allergens, irritants, or conditions that cause your asthma symptoms to worsen. It’s important to know what triggers your asthma symptoms. Triggers vary from person to person, so you should learn which specific ones affect you. While it may be impossible to avoid every single asthma trigger, there may be things you can do to help. Being able to identify and avoid your triggers is important.

Below you’ll find tips on dealing with various types of asthma triggers. If you are able to reduce your exposure to some of these triggers but you still experience asthma symptoms, talk with your healthcare provider.

Select the triggers below to find out more.
                           
Cockroaches
Many people with asthma are allergic to the dried droppings and remains of cockroaches.
  • Keep food and garbage in closed containers (never leave food out)
  • Use bait or traps to eliminate cockroaches
  • If a spray is used to kill roaches, stay out of the room until the odor goes away

Decrease in air pollution associated with decrease in respiratory symptoms among children
THE JAMA NETWORK JOURNALS

Decreases in ambient air pollution levels over the past 20 years in Southern California were associated with significant reductions in bronchitic symptoms in children with and without asthma, according to a study appearing in the April 12 issue of JAMA.

Childhood bronchitic symptoms are significant public and clinical health problems that produce a substantial burden of disease. Ambient air pollutants are important determinants of bronchitis occurrence. Since 1992, significant improvements in air quality have been observed across Southern California due to a broad range of air pollution reduction policies and strategies. Kiros Berhane, Ph.D., of the University of Southern California, Los Angeles, and colleagues examined whether improvements in ambient air quality in Southern California were associated with reductions in bronchitic symptoms in children. The study involved children (age range, 5-18 years) from 3 groups, and was conducted during the 1993-2001, 1996-2004, and 2003-2012 years in 8 Southern California communities.

A model was used to estimate the association of changes in pollution levels with bronchitic symptoms. The primary measured outcome among children was annual age-specific prevalence of bronchitic symptoms during the previous 12 months based on the parent’s or child’s report of a daily cough for 3 months in a row, congestion or phlegm other than when accompanied by a cold, or bronchitis.
The 3 cohorts included a total of 4,602 children (average age at baseline, 8 years; 49 percent girls; 45 percent Hispanic white) who had data from 2 or more annual questionnaires. Among these children, 19 percent had asthma at age 10 years. The authors found that decreases in ambient concentrations of nitrogen dioxide, ozone, and particulate matter with an aerodynamic diameter less than 10 µm (PM10) and less than 2.5 µm (PM2.5) were associated with significant decreases in bronchitic symptoms in children with and without asthma. The reductions were proportionally larger in children with asthma and remained similar when examined at 10, 13, and 15 years of age during the follow-up period. Among patients with asthma, the reductions in bronchitic symptoms tended to be larger in boys and among children from households with dogs.

“While the study design does not establish causality, the findings support potential benefit of air pollution reduction on asthma control,” the authors write.
