I agree with you, ignorant fucks here who don't know shit about earth's physical or historical geology. In the recorded human history of 4000 years, last ten years were the hottest with the highest CO2 concentrations. The whole industrial age/revolution wasn't as bad as the last 10 years.
well... 4000 years is a horrible time scale to compare CO2 when the earth has been around for 4.wtver billion years... that's 8.88e^-7.... or 8.88e^-5% ..wtf... yo.. so the earth warms up in 10 years.. like it hasn't done that before humans even even were playing with stones and sticks... and everyone get's their panties in a knot.. seriously chill out....
Fact: I the recorder human history (4000 years or so) earth's average temperature has NEVER been as high as it has been in the last 10 years. Fact: We are deforesting and reproducing ignorant fucks like yourself too fast for the earth to handle. WHO THE FUCK TOLD YOU THAT MORE CO2 means "faster" plant growth? Too much of anything is deadly, too much oxygen in the air will fucking kill you, and too much co2 in the air will do likewise to the plants. Go read about deforestation.
Fact: 1000 years ago the Mediaeval Warm Period was several degrees F warmer than now, and the Cretaceous and Jurassic for example were even warmer than that, where animals thrived!
Fact: We ARE deforesting too fast, which concerns me as well.
Fact: Farmers inject CO2 into their greenhouses to make their plants thrive - and they do quite nicely.
Fact: CO2 concentrations in the past were 4000-7000ppm compared to 380ppm today, with no runaway greenhouse, which is why we're talking now!!
Fact: The Apollo astronauts breathed pure oxygen the entire spaceflight and moonwalks with no ill effects.
Fact: CO2 is what plants inhale and is vital for their photosynthesis. With adequate water and other nutrients, 100% CO2 in their atmosphere poses no problems.
It may be helpful to the world if you had some itty bitty understanding of what you're trying to rebuke. Hmm??
OMG, pure oxygen? are you kidding me? Do you know 100% pure oxygen is toxic for your lungs? It can actually harm your brain. Long term exposure to 100% oxygen will damage your brain 100% oxygen is a neurotoxin. Are you suggesting that 3 astronauts spent 14 days in a space shuttle and space suits with 100% oxgen without any harmful effects? I find that extremely hard to believe. No living thing can survive 14 days in 100% pure oxgen environment, well maybe microscopic organisms.
true.... the Apollo 1 mission (the one that burned up on the launch pad) was inface 100% oxygen.. well.. that is a mixture for disaster.. i love it how people think they have the "facts".... (btw .. .im not saying u have the wrong facts 'cause ur spot on)

Fact: Temperature change PRECEDES CO2 levels.
Fact: CO2 levels were far higher in the past - even during massive ice ages & have no correlation to temperature.
Fact: More CO2 = faster plant growth to feed nations.
Fact: Enjoy the warm periods - grain doesn't like to grow in ice.
Fact: Overpopulation will be a massive problem that nobody seems to care much about.
Fact: REAL science is stifled.
Fact: We are deforesting and reproducing ignorant fucks like yourself too fast for the earth to handle.

Do some research on Apollo and you'll discover it's true.
I highly doubt that even .0001% of new building is for underground housing... why do you say that people are building underground?
DAY AFTER TOMOROW IS A MOVIE!
Watch 28 Days Laters... thats what zombies would be like...
None of your comments make any sense.
I'm sorry.
