The earth has went through several mass extinctions in the past.

 

The earth was almost completely covered in ice at one point

 

The earth was almost completely free of ice at one point.

 

Yet here we are.

 

Every day there are hundreds of new materials/physics/energy breakthroughs - assisted by ever increasing AI capability. https://phys.org/new...amo-effect.html

 

Spraying reflective substances into the air is Cro-Magnon engineering. I am talking about new technology. 

 

I am optimistic.

 

You are simply naïve.

 

The abovementioned events happened on timescales incompatible with human ones. Humankind can't/won't be interested in waiting 10 000+ years for reversal of sea levels and this can't be fixed in 50 years (what most people max planning horizon is). These processes don't work like that.

The Earth may go through another Ice Age at some point in the future but it won't be due to humans and they certainly can't do anything about it.

Humanity can probably prevent the next ice age by manipulating the greenhouse gases composition. Unfortunately warming up the planet is easier than cooling it...

Just another development (among hundreds this week) in the development of clean energy: https://www.nanotech...fuel-with-light

 

Obviously, creating useful fuel directly from CO2 and sunlight is basically neutral for atmospheric concentrations, but it is not hard to imagine creating a carbon form that is easily sequestered.

as climate change geta worse my belief is all animals, insects etc will flock to russia given how huge it is of nature. On america continent they will probably go to canada.

Once earth runs low enough on resources and becomes hot enough it will activate sn ice to save itself by decrasing its temp from inside.

It has been about 50 years since the initial research that predicted the average temperature of the earth would warm because of increasing CO2. (It has gone up about 0.5 - 1.0 C, depending upon which source you quote)

 

It has been about 35 years since James Hansen kicked off the global warming apocalypse industry.

 

35 years of "code red on the climate", "point of no return", insert your favorite hyperbolic statement. It still does not appear to be an existential threat. AI/AGI is probably still at the top of the list.

 

The arctic sea ice might finally disappear in the next couple of years and the scientists who predicted it would melt 20 years ago can finally say "see, I was right".

 

The saddest part of the whole global warming apocalypse industry is that they mostly refuse to engage in rational productive debate about a good way forward - developing new clean energy - specifically more fusion/fission energy. The aforementioned James Hansen tarnished his reputation (among peers) by proposing the most beneficial way forward was nuclear energy.
