It seems truth often matters little when pushing climate crisis

Claim in media around world that ‘climate crisis’ makes more heat deaths

No: for constant population, both heat and cold deaths down

We only see more cold and heat deaths if we don’t adjust for population:

because more and especially many more older people

We are badly informed when media claims that this is because of climate

In general, all age groups die less of cold
Of 95+ year olds, 1.5% die each year from cold (29% die of all causes each year)

Heat deaths up, but from very low base, of 95+ year olds, 0.06% die each year

Heat deaths very enlarged:

Most age groups die more, but youngsters (0-19) die much less, likely because more hospital birth

Because this age group is *much* larger, its reduction outweigh increase for old

edition.cnn.com/2021/08/19/hea…

ihmeuw.org/5d6x
With a constant population, we see 670,000 fewer die from cold, and 37,000 fewer die from heat each year

We only see increasing heat and cold deaths because of increasing and aging population

Don't blame it on climate

Global inequality is lower today than last 140 years

Ineq increase hugely in 1800s bc industrialized world pulls away

Ineq decline as poor world (China, India) starts gaining

Gini: 0=no ineq, 1= total ineq

New, amazing data from @PikettyLeMonde & co
wid.world/document/longr… Image
Income development 1820-2020:

In China, per person income dropped from 82% of world average in 1820 down to 20% in 1980, before rising to 109% in 2020

In Indonesia, it dropped from 57% in 1820 to 16% in 1950, up to 68% in 2020

What drives global inequality?

Blue line shows domestic inequality: high, but lower in 1950s-80s

Orange line shows inequality between nations: increase dramatically after rich world industrialization, decline after 1980 as poor world is gaining again

The world’s top medical editors argue for climate action with core argument: Global heat deaths for 65+ increased 50+%

But don’t tell you that the number of 65+ has increased almost as much

Oops

The world’s top medical editors argue for climate action

With amateur mistake: they forget to adjust for more old people

They should correct their paper (but of course, it would also neuter it)

The world’s top medical editors for climate action

Vastly overstating heat deaths
And entirely ignoring dramatic reduction in cold deaths

How are we well informed by this?

You're being lied to:

Report claims disasters 5x over past 50 years

But because of better reporting

How do we know?

Take well-measured US tornados:

They haven't increased at all

New Nature study shows net-zero will cost each American more than $11,000 every year by 2050

That's ~100x more expensive than what Americans are willing to pay

Current, super-expensive climate policy simply won't get net-zero past voters

nature.com/articles/s4155…
New Nature study shows net-zero will cost the US more than 12% of its GDP every year by 2050

For comparison, Social Security today costs 5% of US GDP and Medicare/Medicaid 6.4%

Implausible voters will accept such cost of net-zero

New Nature study shows net-zero will cost the US more than $4 trillion every year by 2050

For comparison, Social Security today costs $1.1tr and Medicare/Medicaid $1.4tr

Heatwave magnitude in the US was highest in the 1930s

How do we know? Follow the science:

It is the conclusion from the US Fourth National Climate Assessment "heat wave magnitude reached a maximum in the 1930s."

science2017.globalchange.gov/downloads/CSSR… p191
Heatwave magnitude in the US was highest in the 1930s

How do we know? Follow the science:

EPA has one — and only one — century-long heat wave indicator. It shows heatwaves strongest in 1930s decade and maxed in 1936

epa.gov/climate-indica…
The official climate information of the US government tells us that over the last century, US heatwaves peaked in the 1930s

This is incontrovertible

But some don't like this information

Climate scientist Dessler argues "that just doesn't look right"

UN routinely warns us that we have just a few years left until catastrophe:

In 1972, half a century ago, Maurice Strong, first UN Environment Programme director warned that

the world had just 10 years to avoid catastrophe
