Why Apocalyptic Claims About Climate Change Are Wrong

Authored by Michael Shellenberger via Forbes.com,

Environmental journalists and advocates have in recent weeks made a number of apocalyptic predictions about the impact of climate change. Bill McKibben suggested climate-driven fires in Australia had made koalas “functionally extinct.” Extinction Rebellion said

“Billions will die” and “Life on Earth is dying.”

Vice claimed the “collapse of civilization may have already begun.” 

Few have underscored the threat more than student climate activist Greta Thunberg and Green New Deal sponsor Rep. Alexandria Ocasio-Cortez. The latter said,

“The world is going to end in 12 years if we don’t address climate change.”

Says Thunberg in her new book,

“Around 2030 we will be in a position to set off an irreversible chain reaction beyond human control that will lead to the end of our civilization as we know it.”

Sometimes, scientists themselves make apocalyptic claims.

“It’s difficult to see how we could accommodate a billion people or even half of that,” if Earth warms four degrees, said one earlier this year. “The potential for multi-breadbasket failure is increasing,” said another. If sea levels rise as much as the Intergovernmental Panel on Climate Change predicts, another scientist said, “It will be an unmanageable problem.”

Apocalyptic statements like these have real-world impacts. In September, a group of British psychologists said children are increasingly suffering from anxiety from the frightening discourse around climate change. In October, an activist with Extinction Rebellion (”XR”) — an environmental group founded in 2018 to commit civil disobedience to draw awareness to the threat its founders and supporters say climate change poses to human existence — and a videographer, were kicked and beaten in a London Tube station by angry commuters. And last week, an XR co-founder said a genocide like the Holocaust was “happening again, on a far greater scale, and in plain sight” from climate change.

Climate change is an issue I care passionately about and have dedicated a significant portion of my life to addressing. I have been politically active on the issue for over 20 years and have researched and written about it for 17 years. Over the last four years, my organization, Environmental Progress, has worked with some of the world’s leading climate scientists to prevent carbon emissions from rising. So far, we’ve helped prevent emissions increasing the equivalent of adding 24 million cars to the road.

I also care about getting the facts and science right and have in recent months corrected inaccurate and apocalyptic news media coverage of fires in the Amazon and fires in California, both of which have been improperly presented as resulting primarily from climate change. 

Journalists and activists alike have an obligation to describe environmental problems honestly and accurately, even if they fear doing so will reduce their news value or salience with the public. There is good evidence that the catastrophist framing of climate change is self-defeating because it alienates and polarizes many people. And exaggerating climate change risks distracting us from other important issues including ones we might have more near-term control over.

I feel the need to say this up-front because I want the issues I’m about to raise to be taken seriously and not dismissed by those who label as “climate deniers” or “climate delayers” anyone who pushes back against exaggeration.

With that out of the way, let’s look whether the science supports what’s being said.

First, no credible scientific body has ever said climate change threatens the collapse of civilization much less the extinction of the human species.

“‘Our children are going to die in the next 10 to 20 years.’ What’s the scientific basis for these claims?” BBC’s Andrew Neil asked a visibly uncomfortable XR spokesperson last month.

“These claims have been disputed, admittedly,” she said. “There are some scientists who are agreeing and some who are saying it’s not true. But the overall issue is that these deaths are going to happen.”

“But most scientists don’t agree with this,” said Neil. “I looked through IPCC reports and see no reference to billions of people going to die, or children in 20 years. How would they die?”

“Mass migration around the world already taking place due to prolonged drought in countries, particularly in South Asia. There are wildfires in Indonesia, the Amazon rainforest, Siberia, the Arctic,” she said.

But in saying so, the XR spokesperson had grossly misrepresented the science.

“There is robust evidence of disasters displacing people worldwide,” notes IPCC, “but limited evidence that climate change or sea-level rise is the direct cause”

What about “mass migration”? 

“The majority of resultant population movements tend to occur within the borders of affected countries,” says IPCC.

It’s not like climate doesn’t matter. It’s that climate change is outweighed by other factors. Earlier this year, researchers found that climate “has affected organized armed conflict within countries. However, other drivers, such as low socioeconomic development and low capabilities of the state, are judged to be substantially more influential.”

Last January, after climate scientists criticized Rep. Ocasio-Cortez for saying the world would end in 12 years, her spokesperson said

 “We can quibble about the phraseology, whether it’s existential or cataclysmic.”

He added, “We’re seeing lots of [climate change-related] problems that are already impacting lives.”

That last part may be true, but it’s also true that economic development has made us less vulnerable, which is why there was a 99.7% decline in the death toll from natural disasters since its peak in 1931.

In 1931, 3.7 million people died from natural disasters. In 2018, just 11,000 did.  And that decline occurred over a period when the global population quadrupled.

What about sea level rise? IPCC estimates sea level could rise two feet (0.6 meters) by 2100. Does that sound apocalyptic or even “unmanageable”?

Consider that one-third of the Netherlands is below sea level, and some areas are seven meters below sea level. You might object that Netherlands is rich while Bangladesh is poor. But the Netherlands adapted to living below sea level 400 years ago. Technology has improved a bit since then.

What about claims of crop failure, famine, and mass death? That’s science fiction, not science. Humans today produce enough food for 10 billion people, or 25% more than we need, and scientific bodies predict increases in that share, not declines.

The United Nations Food and Agriculture Organization (FAO) forecasts crop yields increasing 30% by 2050. And the poorest parts of the world, like sub-Saharan Africa, are expected to see increases of 80 to 90%.

Nobody is suggesting climate change won’t negatively impact crop yields. It could. But such declines should be put in perspective. Wheat yields increased 100 to 300% around the world since the 1960s, while a study of 30 models found that yields would decline by 6% for every one degree Celsius increase in temperature.

Rates of future yield growth depend far more on whether poor nations get access to tractors, irrigation, and fertilizer than on climate change, says FAO.

All of this helps explain why IPCC anticipates climate change will have a modest impact on economic growth. By 2100, IPCC projects the global economy will be 300 to 500% larger than it is today. Both IPCC and the Nobel-winning Yale economist, William Nordhaus, predict that warming of 2.5°C and 4°C would reduce gross domestic product (GDP) by 2% and 5% over that same period.

Does this mean we shouldn’t worry about climate change? Not at all. 

One of the reasons I work on climate change is because I worry about the impact it could have on endangered species. Climate change may threaten one million species globally and half of all mammals, reptiles, and amphibians in diverse places like the Albertine Rift in central Africa, home to the endangered mountain gorilla.

But it’s not the case that “we’re putting our own survival in danger” through extinctions, as Elizabeth Kolbert claimed in her book, Sixth Extinction. As tragic as animal extinctions are, they do not threaten human civilization. If we want to save endangered species, we need to do so because we care about wildlife for spiritual, ethical, or aesthetic reasons, not survival ones.

And exaggerating the risk, and suggesting climate change is more important than things like habitat destruction, are counterproductive.

For example, Australia’s fires are not driving koalas extinct, as Bill McKibben suggested. The main scientific body that tracks the species, the International Union for the Conservation of Nature, or IUCN, labels the koala “vulnerable,” which is one level less threatened than “endangered,” two levels less than “critically endangered,” and three less than “extinct” in the wild.

Should we worry about koalas? Absolutely! They are amazing animals and their numbers have declined to around 300,000. But they face far bigger threats such as the destruction of habitat, disease, bushfires, and invasive species.

Think of it this way. The climate could change dramatically — and we could still save koalas. Conversely, the climate could change only modestly — and koalas could still go extinct.

The monomaniacal focus on climate distracts our attention from other threats to koalas and opportunities for protecting them, like protecting and expanding their habitat.

As for fire, one of Australia’s leading scientists on the issue says,

“Bushfire losses can be explained by the increasing exposure of dwellings to fire-prone bushlands. No other influences need be invoked. So even if climate change had played some small role in modulating recent bushfires, and we cannot rule this out, any such effects on risk to property are clearly swamped by the changes in exposure.”

Nor are the fires solely due to drought, which is common in Australia, and exceptional this year. “Climate change is playing its role here,” said Richard Thornton of the Bushfire and Natural Hazards Cooperative Research Centre in Australia, “but it’s not the cause of these fires.”

The same is true for fires in the United States. In 2017, scientists modeled 37 different regions and found “humans may not only influence fire regimes but their presence can actually override, or swamp out, the effects of climate.” Of the 10 variables that influence fire, “none were as significant… as the anthropogenic variables,” such as building homes near, and managing fires and wood fuel growth within, forests.

Climate scientists are starting to push back against exaggerations by activists, journalists, and other scientists. 

“While many species are threatened with extinction,” said Stanford’s Ken Caldeira, “climate change does not threaten human extinction… I would not like to see us motivating people to do the right thing by making them believe something that is false.”

I asked the Australian climate scientist Tom Wigley what he thought of the claim that climate change threatens civilization. “It really does bother me because it’s wrong,” he said. “All these young people have been misinformed. And partly it’s Greta Thunberg’s fault. Not deliberately. But she’s wrong.”

But don’t scientists and activists need to exaggerate in order to get the public’s attention?

“I’m reminded of what [late Stanford University climate scientist] Steve Schneider used to say,” Wigley replied.

“He used to say that as a scientist, we shouldn’t really be concerned about the way we slant things in communicating with people out on the street who might need a little push in a certain direction to realize that this is a serious problem. Steve didn’t have any qualms about speaking in that biased way. I don’t quite agree with that.”

Wigley started working on climate science full-time in 1975 and created one of the first climate models (MAGICC) in 1987. It remains one of the main climate models in use today.

“When I talk to the general public,” he said, “I point out some of the things that might make projections of warming less and the things that might make them more. I always try to present both sides.”

Part of what bothers me about the apocalyptic rhetoric by climate activists is that it is often accompanied by demands that poor nations be denied the cheap sources of energy they need to develop. I have found that many scientists share my concerns.

“If you want to minimize carbon dioxide in the atmosphere in 2070  you might want to accelerate the burning of coal in India today,” MIT climate scientist Kerry Emanuel said.

“It doesn’t sound like it makes sense. Coal is terrible for carbon. But it’s by burning a lot of coal that they make themselves wealthier, and by making themselves wealthier they have fewer children, and you don’t have as many people burning carbon, you might be better off in 2070.”

Emanuel and Wigley say the extreme rhetoric is making political agreement on climate change harder.

“You’ve got to come up with some kind of middle ground where you do reasonable things to mitigate the risk and try at the same time to lift people out of poverty and make them more resilient,” said Emanuel.

“We shouldn’t be forced to choose between lifting people out of poverty and doing something for the climate.”

Happily, there is a plenty of middle ground between climate apocalypse and climate denial.

  1. My opinion? Climate is ALWAYS changing! I remember as a child (in the 40’s and 50’s) we had many days of summer that were in the 90’s! Today, there are maybe 2 or 3. More damage is done by the creation of a false narrative, than by facts. I guess our liberal colleges are molding the truth to fit their political motives.

    • Agree! False science with made up facts are putting this environment in danger. This is just a Globalist “money grab” for Globalist handlers, and their representatives to make big money by using OUR money.

      Liberal colleges need a job. They don’t want to actually teach but indoctrinate. All with political motives. Just look at the 3 so-called Constitution professors who really have no clue about the Constitution. Just full of hate because their Party or Candidate didn’t win.

      GOD BLESS PRESIDENT TRUMP! GOD BLESS THE USA!

      • As AOC’s boy-toy said, “It’s not about climate change”. It’s about control and profit for big-money interests who hope to make a buck on our ‘fears’.

    • You are right. Archeologist have found that there are deserts where seas used to be and villages under the melted ice , which means it wasn’t always frozen.
      NASA has to continually change the direct North for the computer guidance systems, because the poles are trying to switch places. Which according to science it has done about 2 time’s in history.

  2. https://www.breitbart.com/politics/2019/12/06/proudly-pro-life-nj-senator-casts-first-vote-against-funding-planned-parenthood/

    Wow, Thank you Senator Testa.

    “From a larger fiscal perspective, with Governor Murphy raising spending by billions and demanding massive tax increases year after year, I don’t believe this is something we can afford,” the senator said. “Along with their misguided sanctuary state policies, spending millions on abortion providers is another example of the misguided priorities of Trenton Democrats.”

    “New Jersey Right to Life is fighting against the funding bill.

    “The state of New Jersey should not be using taxpayer money to fund a private nonprofit organization,” Right to Life Executive Director Marie Tasy said. “It’s important to note that Planned Parenthood opted out of the Title X program because they refused to comply with the regulations that they physically and financially separate their abortion business from family planning services.”

    Why I put this under “climate change” is this is the Globalist plan for overpopulation. Sick as it is AND make money off of it by selling baby body parts.

    Murphy, the German Ambassador for Obama, who thinks he knows New Jersey, has been spreading the Globalist wealth with OUR money. And as you can see, raising our taxes because he can’t stand that people in New Jersey have money in their pockets because of what President Trump did.

    GOD BLESS PRESIDENT TRUMP! GOD BLESS THE USA!

  3. https://www.breitbart.com/politics/2019/12/06/emma-thompson-delivers-end-times-climate-prophecy-foretells-pets-eaten-crop-failures-and-ruined-lives/

    Sorry Ms. Thompson, but your “crystal ball” foretells nothing. I have to laugh. People sent rabbits down to Venezuela to help with the food shortage. You know, you raise meat rabbits and then you eat them. But no, Peta went down and made them think they were “pets”. so is that what you mean by “eating your pets” Ms. Thompson? Shaming people who need food is not the way to get your “climate change” mantra across.

    So who’s really hurting our Environment? Who’s cause is really hurting those who need food?

    GOD BLESS PRESIDENT TRUMP! GOD BLESS THE USA!

    • Sorry, in New Jersey it’s the environmentalists. There plans to clean up superfund sites thru sewer systems have failed miserably. Polluting our drinking water to a point that a little bit of man-made uranium is A-OK. But don’t worry environmentalists helped pass that law. lol

      Have to laugh here as the representatives have been pushing the oil fired homes into gas because of this farce. Oil fired homes run much cleaner than gas. But then again the manuscript of “oil business bad” wouldn’t work.

      GOD BLESS PRESIDENT TRUMP! GOD BLESS THE USA!

    • If Thunberg is right then all the Geological Scientist are wrong. My bet would be that Thunberg is nothing more than an alarmist and that Climate change is nothing more than Mother Earth doing what Mother Earth has done since the beginning ,Change.

  4. For a more accurate look at the why’s and when’s of “Climate Change” read the book”Inconvenient Facts” written by Gregory Wrightstone.

  5. The problem, I believe, is that the initial impact of climate change is so gradual that it allows people to ignore it. We’re like the apocryphal frog in a pot coming to a boil. It seems fine in the pot until too late the frog realizes what is happening and is cooked. There are clear impacts of climate change going on right now, for example, the Arctic is warming faster than other parts of the planet and this has had consequences on sea ice and on the jet stream sending blasts of cold air further south in the U.S. Northeast while Alaska basks in record heat. The loss of land ice in the Himalayas is going to have serious consequences for parts of India that depend on it for water.

    Mr. Shellenberger is quite right to question involvement of climate change in events such as California fires, but notice he says “primarily not climate change”. The impact of climate change is very small in observed events, but it will be getting larger and larger. Tidal flooding and storm surges in Florida is getting very slightly worse, but it’s going to get more worse.

    What has people like me worried is that while impacts are very small right now, it will surely accelerate, and right now the resistance to doing anything about climate change is leaving me with the fear that we will realize too late that we are being cooked.

    Professor Adrian Raftery, a statistician at the University of Washington, and colleagues were unhappy with IPCC’s ad hoc forecasts for climate change so they collected a lot of data and produced a statistical forecast. Their conclusions, published in Nature, was that the planet’s population would level off due to a “demographic transition” resulting in a leveling off of global warming. They further concluded, though, that it was unlikely to level off at less than 2 degrees Celsius. This is a hopeful result, but it also means some dire effects. Our world, at 2+ degrees Celsius greater, will be very different from our current world.

  6. People who are worried about ‘climate change’ are those who are too lazy or inept to adapt.
    The world is cyclical, and as any motional ball will do, is to rotate and wobble. That was set in motion billions of years ago, and inevitably will change. The earth’s axes have changed over time, causing the cyclical winds and storms to move with it. Just like another poster pointed out, archaeologists have found deserts where seas once stood, and towns under miles of ice. Earth’s inhabitants have adapted in the past, and must always in the future. Yes, there’s a time limit too. Nothing lasts forever. Stars and planets have expired, as discoveries of our solar system have proven. One day the motion will come to an end. Many, many climactic events have happened long before our industrial age started, so that alone proves we really don’t have much to do with what the earth experiences. Use your brain and adapt, or move; just like our ancestors had to do.

  7. I would hate to think what all these lefty teachers are teaching the children !!! It is science fiction, not science!
    Telling them the false narrative that civilization will end in 10 to 12 years, and egged on by Tom Steyer and Soros etc (when they know better), but it suits their narrative and partisan politics. Disgracefull !!!
