How to deal with Global Warming?

2016 report as per above.

“While the detection of greening is based on data, the attribution to various drivers is based on models,” said co-author Josep Canadell of the Oceans and Atmosphere Division in the Commonwealth Scientific and Industrial Research Organisation in Canberra, Australia.

2020 report as per below

NASA satellites have been observing increased green cover on land, which is thought to be due to intensive agriculture to feed growing populations and ambitious tree-planting programs

“China and India account for one-third of the greening, but contain only 9% of the planet’s land area covered in vegetation – a surprising finding, considering the general notion of land degradation in populous countries from overexploitation,” said Chi Chen of the Department of Earth and Environment at Boston University, in Massachusetts, and lead author of the study.

my map shows most of the land has greened and your links support what I said, the world is greening as we warm. The recent report I saw said CO2 accounted for 70% of the greening, 9% for Nitrogen, and the remaining 21% for several factors, like warmer and wetter air. I think I posted the link in the other news thread.

Change means disruption. Disruption means suffering and death. Some foods will disappear. Some species will go extinct. Humans will not be one of them. In the end, there may be fewer of us, and most likely we will be worse off as a whole.

Also many, probably most species adapted to past climate change through continuous range shifting. This time massive global habitat loss means that's not viable for most species. They are stuck.

Global warming expands habitat. The disappearance of the Megafauna and Clovis culture was a result of cooling

All we need to do is convince conservatives the climate is transitioning, and they'll try to stop it.

How does showing a chart going back 12,000 years explain events that occurred over 12,000 years ago?

[Berzerker]

The purpose of the graph was to show the rapid warming when the YD ended, not the onset of the cooling 1300 years before. The extinction was ongoing during the YD but it was not the warming that caused it.

Berz what evidence do you have that the rate of warming would be any easier for our civilization now than it would have been back then? Also, as I mentioned above, back then wild species could substantially shift their ranges. That's dramatically more difficult for most species today due to habitat loss.

I like that the extreme warming at the beginning of the chart briefly had time going backwards. That might explain Friday afternoons at work.

Now put in that graph the expected 2° C increase over 100 years, and tell me it will only have minor effects on the biosphere and the economy.

Also, your chart is horribly off-scale at the start:

the scale is concerned with the Holocene, not the Younger Dryas

The rate of warming back then aint possible now nor was the warming the cause of the YD extinction, on the contrary. Habitat was much more limited because of ice sheets and the cold climate. Warming and CO2 aint the cause of habitat loss, we are.

[N35t0r]

The rate of warming in the past decades is much faster than what happened back then.

capitalism is just a legal way to make money off killing people

As opposed to communism, which is a legal way to kill people just for the sake of it.

I didn't say global warming caused the habit loss, I said habitat loss has made species adaptation to climate change nearly impossible in most cases. Farmland is not habitat for the overwhelming majority of megafauna and not even for most invertebrates. Also, the rate of warming experienced then could be exceeded by a methane spike.

[pchang]

Perhaps if you had couched habitat loss as part of the global capitalist conspiracy, Berz would accept it.

[Berzerker]

Habitat loss is inevitable under capitalism, there's gold in them thar hills
