Indeed. Every Presidential Administration since the Johnson Administration in 1965 has been fully briefed on the climate changing effects of our FF GHG emissions. All since Nixon instead chose to kick the mounting human impact can down the road for future generations to suffer from. Like us today.
Wrong. All the observed warming since 1950 or so is driven by human activities, primarily the human burning of fossil fuels.
Sorry, I don't retain institutional access anymore so I'm in the dark right now, too.
The US press is owned by billionaires with interests inimical to the vast majority of citizens. American Pravda.
Not odd. The methodology used hasn't been independently verified. This is normal scientific process.
A ghg "runaway" a la Venus is unphysical for the Earth.

Restating scientific evidence is not arguing. It's how scientists work. Kvetching and handwringing noted.

We're a long way from ocean heat sink saturation.

Not really. In the eastern US, the global geoids represent coastal sea level relatively well.
Thanks for the implicit admission that you're just here to troll. Whether you actually just lack understanding of the science or just choose to ignore it doesn't really matter at this point.
Troll reported and blocked. All should do likewise.
Context, not rationalization. If you have a cogent point to make, please plainly state it.

Carbicide, or something greater, is the test for all emergent sentiences.
Essentially, a Hothouse Earth (more than 4°C warming by 2100) would be like our civilization being hit by a bus. From Steffen et al 2018:
"The impacts of a Hothouse Earth pathway on human societies would likely be massive, sometimes abrupt, and undoubtedly disruptive."

No Venus-syndrome for the Earth, per Venus expert James Hansen:

Hansen notes that it won't take a runaway to undermine civilization as we enjoy it.
As for temperature increases to come, those are driven by our emissions. When those stop, warming stops.
Choices made in the next decade or two set the stage for the next several thousand years. Irreparable sea level rise could force the migration of billions, over the next few hundred years.
Unfortunately, uncertainties abound. Most are dependent on the carbon pathways society actually follows, others are dependent upon if we're actually where we think we are, in terms of how the climate is responding to forcings to-date. Choices matter, in terms of mitigation and adaptation.
The paper refers to Earth's climate having two stable states, one that supports land-based ice and a commmmensurate climate that allowed human civilization to thrive and a hotter one without land-based ice and much more inimical to humans. We near that possible transition.

Temperatures plateau within a decade of the cessation of the burning of fossil fuels...but then remain elevated above preindustrial for centuries before slowly ebbing. Based on many, many studies dating from 2008 or so.

Per Archer 2008, GHG warming will persist longer than nuclear waste.
A really long time.
Sea levels further removed from the source of land-based ice mass losses will rise more while those adjacent will drop. The top panel shows West Antarctica losses, middle shows Greenland losses, bottom shows losses from both.
Yep. Sea levels further removed from the source of land-based ice mass losses will rise more while those adjacent will drop. The top panel shows West Antarctica losses, middle shows Greenland losses, bottom shows losses from both.
By itself, the planting of trees is at best a feel-good endeavor. Even planting a trillion trees would only offset 7.5 years of our FF GHG emissions. A transition away from fossil fuels to readily available alternatives is the real solution.
