Despite breathless climate reporting about ever more fire

The US burned area last year was the lowest this century

It was less than 7% of the 1930s

Climate does increase the burned area

but zoning and forest management are much more important

Thread + refsImage
We actually have good decadal estimates of US burned area from 1900

2023 saw less than 3% of the area that burned each year in 1900s (1900-1909)

Climate change played a minor role in the wildfires that devastated California in the past three years, a panel of experts said

blaming most on land management and development.

"25% ...from climate change, and 75% is the way we manage lands"

Reduction in US burn in the middle of last century is likely due to fire suppression

Part of the uptick over the past decades likely due to climate

But we're badly informed, when e.g. Economist tell us “wildfire in America has quadrupled in 40 years”

And no, US forest area has not decreased since 1900

actually, it has slightly increased

If the entire world keeps burning a crazy amount of fossil fuels

annual burned area in the US will stay about constant

EPA estimates for the Fourth National Climate Assessment, cfpub.epa.gov/si/si_public_r…
Image
If the entire world reduces CO₂ emissions dramatically — about 70% from RCP8.5 — it means just slightly lower burned area in 2100

It should be obvious that zoning and forest management is much quicker, cheaper and will help many more people better, faster Image
More houses are being built in high-risk areas for wildfires

Maybe our first wildfire policy should focus much more on stopping people from building in vulnerable areas?

And then better fire regulation for those who stay?

Despite breathless climate reporting about ever-more fires

US fires burn 5-10x less today

Even with extreme climate emissions, area burned stays about same across century

Climate does increase burned area,

but zoning and forest management much more important

Contrary to what you constantly hear in the media

Global fire in 2023 burned 𝙡𝙚𝙨𝙨 than normal

Yes, Canada burned very much more (constantly reported), but surely the media should also tell you that US, Africa and Europe burned much less?

gwis.jrc.ec.europa.eu/apps/gwis.stat…

Climate alarmists scare us of ever more fire

But NASA satellites show that the world is burning 𝙡𝙚𝙨𝙨

Why don't we hear this?

Congrats to Germany

Super-expensive but ineffective climate policies mean

De-industrialization

with small climate benefit

Germans pay ever more for power

Even before war in Ukraine, costs had increased more than 50% from 2000 to early 2022

to 35 euro-cents per kWh (or 38 US¢)

Not surprisingly, Germans can afford ever less electricity, with consumption per person actually declining since 2017

Wrong:

Just 6 months ago, the International Energy Agency predicted that rapid replacement with electric cars would mean gasoline demand peaked in 2019

Climate political correctness = bad predictions

The International Energy Agency has gone all-in claiming/hoping that the end of fossil fuels is just around the corner

It puts them in sharp disagreement with Biden's Energy Information Administration, which sees more gas, oil and coal use up to 2050

rogerpielkejr.substack.com/p/going-all-in…
Image
We're being told that electric cars are just about to take over

But remember, most governments (except Norway) can't afford to lavishly subsidize all these cars

Biden's EIA estimates that by 2050, most cars globally will still run on fossil fuels

We need better information

China is super-cold, with Beijing coldest in seven decades

Yet, some just can't help themselves: claiming it is caused by global warming

Apart from sounding stupid, it is also simply wrong

reuters.com/world/china/ch…
Image
Apparently, a climatologist claims that the China cold fits with climate change, because we'd expect more extreme cold waves

But no, that is *not* what the 2023 UN Climate Panel summary report tells us

*All* global warming models show — not surprisingly — less frost, fewer cold days, fewer cold nights

We're told solar and wind future

But when there is no wind and sun?

Batteries!

But

In 2024, storage just 5min

After that, need 100% backup, mostly fossil fuels

In 2050: 47min

Yet, 100% Solar&Wind needs almost three months



frontiersin.org/articles/10.33…
eia.gov/outlooks/ieo/d…
Image
Lots of people suggest batteries can fix intermittency

Yes, but makes 𝗿𝗲𝗻𝗲𝘄𝗮𝗯𝗹𝗲𝘀 𝗰𝗼𝘀𝘁𝗹𝗶𝗲𝗿 because we need to pay for backup

More realistic solar & wind 2x or more

from cheap but very unreliable to expensive and only less unreliable

lazard.com/research-insig…
Image
Most people don't appreciate that

most renewables (RE) to date are only possible because they are backed up by modern fossil (MF) fuel tech

(such as Combined Heat and Power and Integrated Gasification Combined Cycle)

Paris climate policy will cost a sizable fraction of 21st century prosperity

Two new, explosive, peer-reviewed papers show net-zero/1.5°C :

Benefit $4.5 trillion/year

Cost $26.8 trillion/year

Total loss is $1,800 trillion over the century

We must do better

🧵 + refs Image
New special issue of peer-reviewed journal 𝘊𝘭𝘪𝘮𝘢𝘵𝘦 𝘊𝘩𝘢𝘯𝘨𝘦 𝘌𝘤𝘰𝘯𝘰𝘮𝘪𝘤𝘴

First climate economic article shows cost and benefit of 1.5°C target

worldscientific.com/doi/10.1142/S2…
worldscientific.com/doi/10.1142/S2…
Image
Climate benefit of 1.5°C policy is less than 0.5% of global GDP by mid-century and 3.1% by 2100

This is an overestimate, as it assumes change from absurdly high damage (RCP8.5) to 1.5°C

Based on new meta-analysis, 39 papers w/61 published estimates
