Climate models are likely underestimating the impact of climate change on extreme weather disasters, ice sheet disintegration, sea level rise, and deadly typhoons.
Our own research has shown that climate models are likely underestimating the impact that climate change is having on these extreme weather disasters. They are likely also underestimating the potential for ice sheet disintegration, sea level rise, and deadly typhoons.

The incidence of quasi-resonant amplification (QRA) events has tripled over the past half century.
A recent study of ours in the Proceedings of the National Academy of Sciences showed that the incidence of QRA events has tripled (from roughly one QRA event per summer to roughly three events per summer) over the past half century.

China's carbon emissions have entered a flat or falling trend due to an unprecedented surge in renewable energy deployment.
Driven by an unprecedented surge in renewable energy deployment including wind, solar, batter technological, EVs and high-speed rail, China's carbon emissions have entered a "flat or falling" trend, far ahead of the 2030 deadline.

Human-caused warming is the most dominant force shaping the climate.
Mann says they're is a clear signal that human-caused warming is now the most dominant force shaping our climate-without it, those temperature highs from two years prior would have been essentially impossible.

The warming of Earth's surface will cease shortly after carbon emissions are reduced to zero.
One thing the models tell us with greater confidence now is that the warming of Earth's surface will cease shortly after we reduce our carbon emissions to zero.

The dismantling of NCAR undermines the United States' standing in the advancement of climate science.
The dismantling of NCAR very much undermines the United States' standing when it comes to the advancement of climate science.

Climate science will increasingly occur in other countries as the U.S. moves toward second-class status in science and technology.
Climate science will go on, but increasingly in other countries, as the U.S. continues on its current trajectory toward second class status among industrial nations when it comes to science and technology.

The de-funding of the Mauna Loa observatory and the breakup of NCAR are intended as malicious symbolism by the current administration.
The de-funding of the famous Mauna Loa observatory where rising CO2 concentrations were first measured and charted, as well as the eviction of the NASA Goddard Institute for Space Studies from their iconic home on the upper west side of New York City atop Tom's Diner, and the breakup of the equally iconic NCAR climate modeling laboratory perched on the cliffs of the Flatirons in Boulder Colorado, are intended as malicious symbolism by the current administration.

The COP30 global climate summit in Brazil may have been the last opportunity for nations to reach an agreement limiting planetary warming below catastrophic levels.
The COP30 global climate summit in Brazil may have been the last opportunity for the nations of the world to reach an agreement that limits planetary warming below catastrophic (>1.5C/3F) levels.

Bad actor petrostates and the United States have banded together to weaponize the UNFCCC consensus rule machinery to block fossil fuel phase-out commitments.
They have banded together to weaponize the "consensus" rule machinery of the UNFCCC, hijacking the negotiations and blocking any meaningful commitment or timeline for phasing out fossil fuels.

Economic sanctions against countries that refuse to sign on to climate agreements may be necessary because "name and shame" enforcement does not work.
Such measures seems necessary, as the prior enforcement mechanism of "name and shame" simply doesn't work with parties that have no shame.

The increased intensity and destructive potential of hurricanes can be attributed to human-caused warming.
The increased intensity and destructive potential of these storms too can be attributed to human-caused warming.

Climate change may be altering the behavior of the El Niño phenomenon and its impact on the ocean-atmosphere system.
It is possible that climate change is altering the behavior of the phenomenon. And if that's the case, that it may also be altering the impact the phenomenon has on other attributes of the ocean-atmosphere system, including its influence on seasonal hurricane activity.

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.
