Doesn't fit the narrative, but

Great Barrier Reef: Better than ever

Two-thirds of all reefs hit all-time high in 2022

aims.gov.au/monitoring-gre…
Official reef-wide average widely published as the Great Barrier Reef got worse

But when it got better, official average stopped in 2020

Here is the optimal average (least-square) based on their published averages for North, Central and South sectors

aims.gov.au/reef-monitorin…
Dr Ridd, former professor of marine physics at James Cook University, has posted his estimate of the reef-wide average here

with examples of how the average was used to say things getting worse but now, as things are better, doesn't get updated

Today, the Great Barrier Reef is better than ever

But ten years ago, we were told about the "Great Reef Catastrophe"

and how the reef would be almost gone today

Moral of the story:

Don't always believe the scare stories

Refs in 🧵
Here is the 2012 article telling us about the terrible state of the Great Barrier Reef

and about how it will almost halve again by 2022 to 5-10%

Impact of new climate legislation

Unnoticeable: 0.0009°F to 0.028°F in 2100

Why is no media describing just 𝗵𝗼𝘄 𝗹𝗶𝘁𝘁𝗹𝗲 your $369 billion will achieve?

Instead, we're being told:

"the most significant legislation in history to tackle the climate crisis" (Biden)

🧵 Image
The CO₂e reduction estimate comes from the Rhodium group's new reduction estimate

My analysis use the average difference between their current policy and Inflation Reduction Act (IRA). This goes from zero in 2022 to 511Mt CO₂e in 2030.

rhg.com/research/infla… Image
The $369 billion only goes to 2030 (still unclear, but not further)

Low estimate assumes IRA only causes reductions for 2022-30 (underestimate)

High estimate assumes IRA continues 511MtCO₂e reductions every year from 2031-2100 (big overestimate)

Long BBC story about Sri Lanka and tea

and not 𝗼𝗻𝗲 mention that the catastrophe was because the President decided to have Sri Lanka go organic on April 27, 2021

Almost as if this is not politically correct to say?

bbc.com/news/world-asi…
President very clear that he wanted to get rid of synthetic fertilizers for health reasons, not to save money

ft.lk/news/Organic-f…

newsfirst.lk/2021/04/29/sri…
A 20-step plan to transform Sri Lanka into "green socio-economy"

renewable energy
environmentally designed urban houses
reduce banned plastic (?)
25% extra tax on cars

Heatwave: "end of human life"

Standard climate scare

Yet simply untrue

Yes, heatwaves kill (stay cool w/AC+follow advice)

But for Spain

1) cold kills 6x more than heat
2) better adaptation means heat deaths 𝗱𝗲𝗰𝗹𝗶𝗻𝗲

Globally:
cold 9x more deadly
total heat+cold⬇️

🧵
For Spain, cold deaths outweigh heat deaths

Both cold and heat deaths have declined, because of better adaptation (air conditioning, better insulated buildings, better warning systems etc)

sciencedirect.com/science/articl…
Indeed, studies for Spain show that most areas are adapting 𝗳𝗮𝘀𝘁𝗲𝗿 than temperatures are increasing

which is why higher temperatures are leading to fewer heat deaths

We need to be honest about the tremendous cost of net zero emissions. Censoring this information (as the White House seems to suggest) will be terrible both for public discourse and taxpayers' wallets.

foxnews.com/media/bjorn-lo…
McKinsey finds a cost of $19,300 per US family in 2022, increasing every year.
A Nature study shows that a 95% reduction will cost each American more than $11,000 every year by 2050.

Maybe scaring people witless with climate alarmism isn't okay?

(apart from being incorrect)

Howard Breen, climate scared Canadian wants to commit suicide bc climate

vice.com/en/article/k7w…
Climate change is real

But problem, not end-of-world

e.g. climate-related disasters killed ever fewer in 2021 — 98.7% less than a century ago

bc richer and more resilient societies reduce disaster deaths

Climate change is real

But problem, not end-of-world

e.g. weather-related damage losses in % of GDP not increasing but actually declining
