I mean there must a threshold temperature when once reached, chain of events will occur to eventually end all life on earth. (Don’t say it’s already started, because we can still survive at current temperature, right? If not, are you saying were already doomed?)

A lot hotter than it is now. But in 1,000,000,000 years the sun will expand and swallow the earth (Mercury, Venus, and Mars as well) and I doubt that life will survive this event.
At a higher temperature than anything we’ll see for a very long time.
The problem with global warming is not that we’re all gonna die. It’s that a mere 2-3 degree C change will cause massive destruction to our modern society.
Seacoasts will flood and agriculture will be damaged. Rich countries can cope, but the expense will send the world economy into a depression that will make the 1930s look like good times.
In poor countries already struggling to feed themselves many (not all) will die of starvation.
More details here:
The Earth will not be destroyed or become uninhabitable. It’s not a disaster flick. But, unless we do something, it will be very very bad. The worst global disaster in human history.
Well species are going extinct at a rate of 3 per hour. That’s believed to exceed any mass extinction on record. So when people ask this question I often wonder, “What do you want? Ten per hour? Fifty? One Hundred?” Some ecosystems and species are obviously more adaptable than others. Still, I can’t help believing that the large scale migrations of entire species from their historic habitat to new areas is as significant as the extinctions.
science by fear- sad.
move on. nuthin’ to see here.
this is a normal cycle.
move along, go about your business.
At 45 C and above polypeptides in aqueous solution have structural phase transitions. At 60 C and above most hydrated proteins will denature. Most forms of life will find survival difficult at 45 C and impossible above 60 C. There are a few species adapted to life in hot springs and volcanic vents that will continue to do well even at elevated temperatures. The earth’s average temperature is 15 C and AGW is unlikely to produce a 30 C rise. The earth will remain habitable, but many species will become extinct.
we’re going to die? the hell you say
you mean we can’t just keep going theway we been going
somebody ‘s gotta do some thing QUICK!
I’m sure you mean (un)inhabitable and my guess is scientists don’t even know something like that for sure. Maybe our species will evolve and adapt. Think about it, that has happened since the begining of time. That might be part of GOD’s master plan. Did cave men have AC?
