What they believe
-
Climate policy is expensive and has a low success rate in cutting emissions.
Third, climate policy is staggeringly expensive and accomplishes remarkably little. The world has already spent more than $16 trillion on climate measures, with promises of hundreds of trillions more. Yet a landmark study in Science examined 1,500 climate policies across 41 countries over two decades and found that only 4% meaningfully cut emissions.

Global economic analysis shows that reaching net zero costs more than its climate benefits.
Globally, the best economic analysis shows going net zero costs far more than its climate benefits.

Estimates of sea-level rise displacement are overstated when accounting for adaptation.
We are warned that rising seas could displace 187 million people, a figure that assumes humanity does nothing for an entire century. Once you account for the seawalls and adaptation that people obviously undertake, that estimate of displacement turns out to be overstated 600-fold or more.

Unchecked warming is expected to cost between 2% and 3% of global GDP by the end of the century.
But the best climate economists consistently estimate that unchecked warming will cost 2% to 3% of global GDP by the end of the century.

If the entire rich world went net zero by 2050, it would cause a temperature reduction of less than 0.2°F by 2100.
But this is true even for the entire rich world - if it actually went net zero by 2050, it would still cause only a miniscule temperature reduction of less than 0.2°F by 2100.

The world's big development banks are funneling over $85 billion of their scarce funds into climate initiatives instead of health and education.
Worse, the world's big development banks are funneling over $85 billion of their scarce funds into trendy climate virtue-signaling initiatives, starving real basics like health and education.

Implementing 12 specific policies would cost approximately $35 billion a year and save 4 million lives annually.
Altogether, our 12 policies would cost about $35 billion a year - chicken feed compared to the more than $10 trillion needed to deliver the UN's Sustainable Development Goals. That $35 billion would save 4 million lives annually and provide benefits to the bottom half of the world worth a trillion bucks - generating jobs, stability and a safer planet.

Net-zero policies will cost hundreds of trillions of dollars and deliver few benefits.
Rather, it insists that we shouldn't deny the costs of climate policy - and must admit that net-zero will cost hundreds of trillions of dollars and deliver few benefits.

Even if all rich countries reached zero carbon emissions, it would avert less than 0.2°F of warming by the end of the century while causing massive GDP hits.
The main UN model shows that even if all rich countries were to cut their carbon emissions to zero, it would avert less than 0.2°F of projected warming by the end of the century, while imposing massive hits of up to 18% on rich-world GDP by 2050.

Western actions are no longer central to solving climate change.
Leaders from Europe, Australia and Canada, making ever-larger climate promises with ever-emptier rhetoric, ignore the crucial reality that Western actions are no longer central to solving climate change.

Future emissions will come overwhelmingly from developing nations.
While the West dominated carbon emissions in the past, future emissions will overwhelmingly come from China, India, Africa, Brazil, Indonesia and other countries clambering out of poverty.

Unaddressed climate economics might shave 2-3% off global GDP by 2100.
Unaddressed, climate economics shows that it might shave 2-3% off global GDP by 2100-meaning we'll be 435% richer instead of 450%.

Climate policy spending crowds out efforts to tackle poverty, disease, and hunger.
That is money spent on climate that won't be spent on preventing disease and hunger.

What is a korrent?
A korrent is a belief a person has stated in their own words: one sentence stating the claim, backed by a quote and a source, kept at korrents.com.
Under a name here, the quoted block is what they actually said. The korrent beneath it is the claim those words support, in korrents' wording — tap it to see the record, its source, and who else holds it.
Nobody here wrote their own korrents. They are compiled from public statements, and a person can change their mind, which is recorded too.

About the English under a post
Some people here publish in a language other than English. Where they do, this site shows a machine translation beneath the post, in this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the serif above is exactly what the person published, and it is what to quote them on. A translation can be wrong in ways that matter, especially about tone.
Only the post's own words are translated. A quoted post, a linked article and a belief on korrents.com are left in their original language.
