@Matthew96296853@bfacedplague@volcaholic1 Nonsense from John Chewshoes. There is no CO2 “red line of death”. CO2 frequently dipped very low in the past. Your CO2 chart on the other hand accurately depicts the sharp rise in the gas driving modern warming. Temperature is already racing to catch up
@bfacedplague@ArcadiaX1013@volcaholic1@grok The National Academy of Sciences repeatedly cleared Dr Mann and upheld his findings in at least two separate independent investigations. No Grok involved.
Here's the original source article for the Smithsonian exhibition chart you posted. Did you read it?

"Editor's note (11/22/2023): Over the years, we have heard from readers who tell us that they have seen this article being cited by people who deny the reality or seriousness of human-caused global warming. To make it harder for anyone to mischaracterize this article, we are adding this note:
The fact that Earth has been hotter in the past than it is today doesn't prove that recent global warming is natural.Forest fires can have both natural and human causes. So can climate change. It is partly through figuring out what caused the periods like the ones described in this article that we came to understand that carbon dioxide sets the thermostat of Earth's climate.
The fact that Earth has been hotter in the past than it is today doesn't prove that current warming is harmless, either to people or other life on Earth.Some previous hot periods led to global mass extinctions.
The hot house periods described in this article occurred millions and millions of years before humans existed.
They have no bearing on whether modern human civilization can cope with the level of warming we are likely to face if we do not stop adding greenhouse gases to the atmosphere.
Like nothing we’ve ever seen:
Earth’s hottest periods—the Hadean, the late Neoproterozoic, the Cretaceous Hot Greenhouse, the PETM—occurred before humans existed. Those ancient climates would have been like nothing our species has ever seen.
Modern human civilization, with its permanent agriculture and settlements, has developed over just the past 10,000 years or so. The period has generally been one of low temperatures and relative global (if not regional) climate stability. Compared to most of Earth’s history, today is unusually cold; we now live in what geologists call an interglacial—a period between glaciations of an ice age.
But as greenhouse-gas emissions warm Earth’s climate, it's possible our planet has seen its last glaciation for a long time.
@ernstvingerhoe1@rahmstorf Wrong on all counts
CO2 levels are indeed rising, but volcanoes have nothing to do with it. CO2 frequently dipped below 200 ppm in the past with no ill consequences. The chart you’ve posted is from Berner et al, who understand and support modern GHG theory.
Everything that could be going wrong, all in one image.
Climate change, rising seas, corruption. (Beachfront properties are public per Mexican Constitution, although enforcement is lax).
Restitutions to the original communities will be slow in coming.
Some angry investors lol
Profepa informa:
Ante la situación de colapso inminente de la construcción irregular en San Pancho, Nayarit, provocado por los huracanes y tormentas, Profepa acudió al sitio para encontrarse con las autoridades de Protección Civil. Acompañaremos los protocolos de emergencia que determinen para dar prioridad a la protección a la vida, la salud y la integridad de las personas.
La Profepa continuará presente para apoyar y buscar que las medidas que se ejecuten tengan el menor impacto ambiental.
Continuaremos informando.
