Many people think climate change is increasing the frequency of natural disasters but they actually declined by 10% over the last two decades, the best-available data show

“The period since 2000 is viewed as the most reliable for data reliability, but it is safe to say that even since 2000, coverage has improved. So the 10% decline is possibly an underestimate.“ @RogerPielkeJr

Much of what people think about climate change is wrong

Deaths from natural disasters have declined dramatically but more people think they increased than think they decreased

The cost of natural disasters has declined as a share of GDP but more people think their cost went up than down

Neither the Intergovernmental Panel on Climate Change (IPCC) nor any other scientific body predicts climate change will reverse the declining disaster death toll and yet 3x more people believe it will than believe it won’t

US CO2 emissions declined 14% over the last decade but 3x more people believe they rose

Carbon emissions *globally* *declined* over the the last decade and yet 62% of Americans surveyed said they went up and just 10% said they didn’t

Climate change has been one of the most-discussed and most-covered news stories of the last two decades and so much of the responsibility for the public believing things that simply aren’t true comes not from lack of information but rather the constant barrage misinformation.

It is common to hear journalists lament declining overall trust in the news media, particularly among Republicans, but the massive gulf between basic climate facts and what people believe suggests such distrust is warranted & indeed should have declined not risen among Democrats.

This is particularly true because Dems are more likely than Rs to believe false information about many aspects of climate change, as the Google surveys show. (I was a Democrat until April when I changed my party affiliation to “No party preference)

Forty-two percent of Democrats and 35 percent of Republicans agreed with the statement, “More people are dying from natural disasters.”

Seventy-one percent of Democrats and 30 percent of Republicans agreed with the statement, “Climate change is increasing the cost of natural disasters as a percent of GDP.”

76 percent of Democrats and 34 percent of Republicans agreed that “Deaths from natural disasters will rise in the future due to climate change.”

67 percent of Democrats and 43 percent of Republicans agreed that “Carbon emissions have risen in the United States over the last 10 years.”

In reality, carbon emissions declined by 14 percent between 2011 and 2020.

But haven’t disasters hammered banks? Nope. “How Bad Are Weather Disasters for Banks?” asks the title of a recent report by three NY Fed economists. “Not very,” they answer in the first sentence of the abstract.

The reason is because “weather disasters over the last quarter century had insignificant or small effects on U.S. banks’ performance.” The study looked at FEMA-level disasters between 1995 and 2018, at county-level property damage estimates, and the impact on banking revenue.

While scientists expect hurricanes to become 5% more intense they also expect them to become 25% less frequent

What about floods? It’s true that more people are being exposed to them but that’s because cities along rivers are growing. Flood deaths & damages are declining

What about droughts? They’re not increasing in US or globally

What about fires? Warmer temperatures dry out the wood but they don’t increase fuel load, and fuel load determines fire intensity. Forest management not climate change thus determines whether you have high-intensity, crown-burning, forest-destroying fires.

What about shrubland fires in places like Malibu in Southern California? “Ignitions explain more than temperature … One hundred percent were human caused, … powerline failures have been the dominant cause”

What about food production? Technology (eg fertilizer, irrigation, & tractors) will continue to outweigh temperature increases. We produce food in many climates around the world, including very hot and dry ones.

What about sea level rise? We can handle it

How does climate change rank compared to wars, disease, asteroids, super-volcanoes, and tsunamis? Much lower. There’s no *scientific* scenario for climate change posing an existential risk. By contrast, consider an asteroid.

Is there some place you can see an overview of the best-available science, complete with references? There is!

Is there some easy-to-read book you can read that lays out the science on climate change, plastics, meat, species, energy, and food told through fun stories? There is!

Climate alarmism is harmful to mental health and is increasingly used as an excuse by politicians. They blame climate change for bad disaster preparedness and management. We see that with fires, flooding, and hurricanes. That’s bad for many reasons:

Q: If apocalyptic thinking is so easily debunked, why is it so powerful?
