Why we all need to cool down about global warming

Across the rich world, school students have walked out of classrooms and taken to the streets to call for action against climate change.

They are inspired by 16-year-old Swedish activist Greta Thunberg, who blasts the media and political leaders for ignoring global warming and wants us to “panic.” A global day of action is planned for March 15.

Although the students’ passion is admirable, their focus is misguided.

This is largely the fault of adults, who must take responsibility for frightening children unnecessarily about climate change. It is little wonder kids are scared when grown-ups paint such a horrific picture of global warming.

For starters, leading politicians and much of the media have prioritized climate change over other issues facing the planet. Last September, United Nations Secretary-General Antonio Guterres described climate change as a “direct existential threat” that may become a “runaway” problem. Just last month, The New York Times ran a front-page commentary on the issue with the headline “Time to Panic.”

And some prominent politicians, as well as many activists, have taken the latest report from the United Nations Intergovernmental Panel on Climate Change to suggest the world will come to an end in just 12 years.

This normalization of extreme language reflects decades of climate-change alarmism. The most famous clip from Al Gore’s 2006 film An Inconvenient Truth showed how a 20-foot rise in sea level would flood Florida, New York, the Netherlands, Bangladesh and Shanghai omitting the fact that this was seven times worse than the worst-case scenario.

A separate report that year described how such alarmism “might even become secretly thrilling effectively a form of ‘climate porn.’”

And in 2007, The Washington Post reported that “for many children and young adults, global warming is the atomic bomb of today.”

When the language stops being scary, it gets ramped up again.

British environmental campaigner George Monbiot, for example, has suggested that the term “climate change” is no longer adequate and should be replaced by “catastrophic climate breakdown.”

Educational materials often don’t help, either.

One officially endorsed geography textbook in the United Kingdom suggests that global warming will be worse than famine, plague or nuclear war, while Education Scotland has recommended The Day After Tomorrow as suitable for climate-change education. This is the film, remember, in which climate change leads to a global freeze and a 50-foot wall of water flooding New York, man-eating wolves escape from the zoo, and spoiler alert Queen Elizabeth II’s frozen helicopter falls from the sky.

Reality would sell far fewer newspapers. Yes, global warming is a problem, but it is nowhere near a catastrophe.

The IPCC estimates the total impact of global warming by the 2070s will be equivalent to an average loss of income of 0.2-2 percent similar to one recession over the next half-century.

The panel also says that climate change will have a “small” economic impact when compared to changes in population, age, income, technology, relative prices, lifestyle, regulation and governance.

And while media showcase the terrifying impacts of every hurricane, the IPCC finds that “globally, there is low confidence in attribution of changes in [hurricanes] to human influence.”

What’s more, the number of hurricanes that make landfall in the United States has decreased, as has the number of strong hurricanes. Adjusted for population and wealth, hurricane costs show “no trend,” according to a new study published in Nature.

Another Nature study shows that although climate change will increase hurricane damage, greater wealth will make us even more resilient.

Today, hurricanes cost the world 0.04 percent of GDP, but in 2100, even with global warming, they will cost half as much, or 0.02 percent of GDP.

And, contrary to breathless media reports, the relative global cost of all extreme weather since 1990 has been declining, not increasing.

Perhaps even more astoundingly, the number of people dying each year from weather-related catastrophes has plummeted 95 percent over the past century, from almost a half-million to under 20,000 today while the world’s population has quadrupled.

Meanwhile, decades of fearmongering have gotten us almost nowhere.

What they have done is prompt grand political gestures, such as the unrealistic cuts in carbon dioxide emissions that almost every country has promised under the 2015 Paris climate agreement. In total, these cuts will cost $1-2 trillion per year.

But the sum total of all these promises is less than 1 percent of what is needed, and recent analysis shows that very few countries are actually meeting their commitments.

In this regard, the young protesters have a point: The world is failing to solve climate change.

But the policy being pushed even bigger promises of faster carbon cuts will also fail, because green energy still isn’t ready. Solar and wind currently provide less than 1 percent of the world’s energy, and already require subsidies of $129 billion per year.

The world must invest more in green-energy research and development eventually to bring the prices of renewables below those of fossil fuels, so that everyone will switch.

And although media reports describe the youth climate protests as “global,” they have taken place almost exclusively in wealthy countries that have overcome more pressing issues of survival. A truly global poll shows that climate change is people’s lowest priority, far behind health, education and jobs.

In the Western world, decades of climate-change exaggeration have produced frightened children, febrile headlines and grand political promises that aren’t being delivered. We need a calmer approach that addresses climate change without scaring us needlessly and that pays heed to the many other challenges facing the planet.
