I too often read "The planet is dying! 😱"

It is not. The planet is adapting to what we're doing. There will always be a rich ecosystem on our planet.

But that ecosystem will adapt to the point where we no longer have a place in it.

No, the planet is not dying. We are.

Please understand that this planet is much more powerful than we will ever be. In geohistoric scale, we are a flyspeck. Thinking that we would be able to extinguish the life on this planet is rather arrogant. No, not even with nukes. All we will accomplish is our own extinction.

@KleineMaulwurf just insane. It's all in this teaser from 100 yrs ago (give or take some comfirmatory studies)

@grob @KleineMaulwurf Not quite. First of all, Arrhenius was off by a factor of two in his estimate of climate sensitivity. Secondly, he corrected the numbers (too far) later. Thirdly, he was convinced that this warming would take hundreds of years and would actually be beneficial (reasonable from his perspective at the beginning of the 20th century).

However: it was later discovered that the oceans take up most of the emitted CO2. It took until the 1960s to see that this is not enough.

@dgfeist "off by a factor of two" — so by experimental physics standards, he was pretty much spot on?

Consider that he got this precision by measuring moonlight.
