RE: SHOCK UN WARNING: Only 3 YEARS Left to SAVE THE PLANET!!!
Yes, the Earth will be fine if CO2 levels keep increasing. But, most animal life, including humans, will be gone. Five mass extinctions of life have occurred in Earth's history and the sixth mass extinction is well underway. People may not want to accept these scientific facts, but it won't make them go away.
Of course. But implying that man can somehow change this is pomposity at it's finest. We're not even close to being that powerful. Like George Carlin said "the earth will shake us off like a bad case of fleas".
There are so many variables and man has only collected data for the past 150 years. We aren't even close to understanding what our contribution is to this. Of course, it makes sense not to add to the problem, however, I'll bet you that even if we do change our ways so that our carbon footprint is completely invisible, mass extinction will still occur and on the schedule that the earth determines, not what we determine.
Totally agree. The first five extinctions occurred when humans weren't around yet, although for different causes. Even if the sixth mass extinction, whatever its cause (it's probably mostly us), does continue until completion, I think life on Earth will bloom again, but far, far into the future.
