This thread is a compilation of failed or reversed environmental predictions/projections, and the motives and interests behind them. I have archived hundreds of these and will continue to add them to this thread over time.

Let's start with a senior UN environmental official who, in 1989, predicted climate change would be irreversible by 2000.

In 2010, the UN's Intergovernmental Panel on Climate Change (IPCC) declared claims published in its 4th report that the Himalayan glaciers could melt by 2035 are false.

In 2000, a climate scientist at the University of East Anglia proclaimed that within a few years snowfall will become "a very rare and exciting event".

Some educated estimates place more snowfall on Scotland's hills and mountains in 2014 than anytime in the last 69 years.

In 2011, the International Energy Agency proclaimed climate change would be irreversible by 2016.

Yes, it's currently 2019 and, naturally, there are other organizations making the same argument last year and this year too (the time limit is "12 years" now).

But you must be "mad"/a "denier" not to trust them!

In 2009, Prince Charles, the next King, proclaimed we had just 96 months to prevent irreversible climate change.

Later that same year, the Prime Minister of the UK proclaimed we had just 50 days.

In 2006, former Presidential candidate Al Gore proclaimed we have 10 years left until we reach the point of no return. Did we make it past 2016?

Of course, it's not all warming: in 1972, after a meeting of 42 scientists, academics from Brown University sent a letter to President Nixon warning him of their general consensus around the grave threat of global *cooling*.

Just three years later, the New York Times was also very concerned about the forthcoming ice age.

In the first paragraph it assures us that "scientists are firmly convinced". *Gasp*.

Four years later (1979) and scientists featured by the New York Times were predicting the increase in co2 could cause...

...global cooling.

There are many more of these from the New York Times (I'll add more to the thread later). An NY Times book review from 1976 despairs at how the warnings are falling on "deaf ears".

You'll note they were referring to a "climatological consensus" in 1976 too.

Of course, in 1980 the concern among a "lot of scientists" were their predictions about acid rain (again, "pollution" was the main target).

Their solution? Shockingly (sarcasm), they wanted money to fund a $100 million "federal acid rain assessment program".

Back in 1971, The Washington Post was also getting in on the act. Naturally, the problem was, again, "fossil fuels".

Anyone would think there's a politically motivated theme here.

And yes, WaPo reported the scientist is a "first-rate atmospheric physicist".

Here's one of Time's efforts from 1974. "When meteorologists take an avg. of temperatures around the globe, they find the atmosphere has been growing gradually cooler for the last three decades. The trend shows no signs of reversing".

Sound familiar?

And this particularly shocking revelation from Time also sounds familiar (see above) but has an altogether different conclusion: "Areas of Baffin Island in the Canadian Arctic, for example, were once totally free of any snow in the summer; now they are covered year round".

Back to warming (though there are many more on "cooling", as well as every other predicted catastrophe that never pans out):

In 2007 we were informed by climate models that summers in the Arctic will be ice-free by 2013.

In 2009, Al Gore was on the bandwagon again, proclaiming, actually, it will be "nearly ice free" by 2014.

Still not convinced? In 2013, a US Department of Energy backed research project predicted the date the Arctic would be ice free during summer months was actually 2016.

Apparently, it "uses complex modelling techniques that make its projections more accurate than others."

Wait! No! In 2016, a Professor of Ocean Physics at Cambridge proclaimed the actual date will be "next year or the year after".

The latest prediction? 20-40 years, apparently.

To be clear, it's not about whether there will or will not be ice free summers, or even the significance of that, it's about the inability of their methodologies to predict it.

Source: The Guardian

In 2010, a geosciences professor warned us the entire ice mass of Greenland is facing a "tipping point", and that "sometime in the next decade we may pass that tipping point".

In 2004, the Guardian obtained a secret report by the Pentagon warning that the UK will be a "Siberian climate" by 2020. It also warns, "As early as next year widespread flooding by a rise in sea levels will create major upheaval for millions".

Of course it's not just extreme weather we have to be panicked about, in 2005 the UN warned us that we could see 50 million environmental refugees by 2010.

What happened? Well, according to census data, many of the areas in China and the US highlighted by the UN as likely to be the source of environmental refugees are actually among the fastest growing cities in their respective countries. https://asiancorrespondent.com/2011/04/what-happened-to-the-climate-refugees/

Naturally, the UN followed up this failed prediction by deleting the map from its website.

Still worried about impending doom? Fear not. Despite acknowledging the doom-laden predictions about rising sea levels after his electoral victory in 2008, Barack Obama recently purchased a $15 million beachfront property.

Either $15 million means nothing to him, or he doesn't put much stock in the NOAA's (more on them later) data. Oh, and Al Gore also bought an $8.9 million ocean view villa in 2008. Seems this climate change stuff really pays.

Anyway, I addressed the IPCC's 4th report earlier but what about its 3rd report? This is one of the contributors to it, the late Dr. Stephen Schneider, a Professor of Global Change. He was in a documentary in 1978 predicting an upcoming ice age. Come the 21st century, he was...

...making dire predictions about global warming.

He was one of a great many, of course. This is a CBS News segment from 1972 of Walter Cronkite relaying the apocalyptic predictions of scientists about the coming ice age.

Cronkite also delivered an Earth Day special in 1970, where Professor Paul Ehrlich, an infamous harbinger of environmental doom, said this (after discussing starvation):

"Should you think you're safe in the United States you are very sadly mistaken. The picture, then, is not...

...altogether bright...if we don't control our population and environment, [the consequences will] include famine, and plague, and thermonuclear war".

ABC also enjoyed the ice age narrative in the 70s. It cites professionals like Professor Reid Bryson, "the head of the biggest meteorological department in the world", to make its case.

What about the The National Oceanic and Atmospheric Administration (NOAA)? Surely that agency, which is part of the U.S. Department of Commerce, wasn't on the global cooling bandwagon too? Well...yes. Yes it was.

Let's move away from failed predictions temporarily and look at incentives and motives. Why would people who claim "the science is settled" feel the need to criminalize skepticism?

In 2015, 20 climate scientists...

...sent a letter to President Obama urging him to launch a RICO investigation into corporations practicing skepticism.

The actions of this group were motivated by an op-ed written by Senator Sheldon Whitehouse in the Washington Post, which also singled out skepticism among...

...conservative policy institutes for criticism. He refers to it as "the climate denial network".

He's not the only one. Despite the "science being settled", climate activists across the board are trying to criminalize dissent. In 2015, Al Gore and 17 Attorney Generals...

...announced an investigation into energy companies and think tanks over climate change skepticism.

The Attorney Generals issued scores of subpoenas, including one for communications between ExxonMobile and 100 universities, conservative think tanks and academics over...

...a 40 year period.

It doesn't stop there. Attorney General Loretta Lynch announced in a Senate committee in 2016 that discussions had taken place within the DOJ about pursuing civil action again "climate change deniers".

Where are the liberals? They certainly aren't...

...in the Democratic Party.

Let's not forget that in 2014 Democrat Senators, led by Senator Harry Reid, tried to rewrite the First Amendment.

Of course, such people are even writing academic journals with titles like "is climate denial a crime?" and "can responsibility for climate change damage be criminalised?"

Their proposal? They believe the "deception" is "punishable as criminal fraud under several United...

...States statutes".

Despite the abysmal track record of climatologists and supranational and governmental organizations in making environmental predictions, some even want to frame climate change skepticism as a "crime against humanity".

UPDATE: a video showing the commonality between environmental protests in 1970 and today.

In both cases, groups held "die-ins", broadcasters predicted doom, kids took time off school and the "gas mask" narrative was employed.
