There’s the distinct possibility of 8c change by 2100 under business as usual. 8c means palm trees at the arctic and no clouds ever forming. If you think that’s a tenable position for life then you’re fully on the denier side.
Furthermore your claim on "clouds will never form" is plainly wrong, and more likely than not, the opposite of what actually happens in a 8° hotter earth.
Climate change is happening, no real doubt about that, but the mindless apocalyptic claims that are parroted around need to stop, because not only are they wrong, but they also decrease the credibility of actual legitimate claims.
There also have been several points in time where the earth was experiencing mass extinctions and survived those just fine.

> For most economic sectors, the impact of climate change will be small relative to the impacts of other drivers (medium evidence, high agreement). Changes in population, age, income, technology, relative prices, lifestyle, regulation, governance, and many other aspects of socioeconomic development will have an impact on the supply and demand of economic goods and services that is large relative to the impact of climate change.
> The Representative Concentration Pathways 8.5 scenario (RCP8.5), a very high emissions scenario examined by climate scientists, has the Earth’s atmosphere reaching around 1,100ppm by the year 2100. But this would require the world to massively expand coal use and eschew any climate mitigation over the rest of this century.
Also, it’s clearly a “tenable position for life” because temperatures were that high as recently as 55 million years ago, and mammals survived: http://www.bbc.com/earth/story/20150914-when-global-warming-...
The question is can we keep industrial scale food production going? Can we get people enough clean water?
Name another species that can create its own energy, create new materials and cure diseases.
The ones who have contributed the least to climate change will almost certainly suffer the most -- this isn't a matter of whether or not our species will survive, it's a matter of injustice.
Seems to be a very counterproductive way of discussing this.
