With the most optimistic outlook on global warming how soon before the human race is extinct?

Answer 1

I think the most optimistic outlook on global warming is that humans take action to stop releasing such an overwhelming amount of greenhouse gases. If that occurs, the Earth will be able to recover from this unprecidented warming (yes, we're warmer now than the Earth's natural cycling) and humans-- and many other animals-- won't go extinct.

Answer 2

If you watch An Inconvenient Truth, it goes into full detail about all that. Great documentary if you can put with listening to Al Gore's monotone voice for a few hours.

Basically, according to what he said in it, in theory the temperature on Earth will be well beyond unbearable within 50 years. I think its a little far fetched, but I guess that's why not enough people are concerned with it.

The basis of that was from showing a graph of CO2 levels on Earth and their relation to the temperatures over the past 650000 years. The whole graph shows little rises and falls throughout time, which made the difference between modern time and ice age climates. It shows that currently the CO2 levels have gone up over (can't remember the exact number but it was quite substantial) percent in the past 10 years especially, and by using history as a guideline, within this century the temperature will follow suit.

It also covers in detail the relation from rising temperatures to the massive amount of record hurricanes in the past decade. Rather interesting to be honest.

I guess that's not the most optimistic as much as pessimistic look on global warming, but hope it fills you in a bit.

Answer 3

I'm not sure That tit isn't just a great big cycle that the earth keeps going through. Global warming probably won't off the human race anytime soon but those knuckleheads in the mid-east and their ideals might so it soon enough.

Answer 4

if global warming was going to kill us, it would done so after every ice age....there is an ice age, then there is global warming..it is a natural process of the earth....
