On the brink: sixth mass extinction

where did i say we were not having an affect. i said we are not causing it. if you had bothered actually looking at the whole chart you would have noticed that about 330,000 years ago co2 was at least as high as it is today and maybe a little higher. so tell me how in the world did we get that much co2 in the atmo at that time. and you are like all of the other "man made climate change" people if the facts dont fit what your trying to sell then those facts arent important. also looking at that chart again, the last peak. the temps were higher than today and the co2 was lower. so if co2 is what...

that isnt what the chart says. the chart shows the opposite in fact, the higher the dust the lower the temp. now why would that be, maybe because the dust reflects the radiation away from the earth. another point i would like to make, i dont know if i can find this info to link to or not. but the last 10,000 years has been the earths most stable climate ever. http://www.ncdc.noaa.gov/paleo/ctl/clihis10k.html Charts are only as good as the understanding you have of what created the trends.

i am not saying that climate change isnt happening. i am just saying it isnt man made. man may be helping it along, but we are not causing the climate to change. this planet goes through climate change ever 300,000 years. we are currently at the peak of that time period. so in about 150,000 years we will be in another ice age. There have been about 30 natural climate shifts since the end of the Younger Dryas (about 10,660 BP). This one is different. Why do I think humans are involved? CO2 levels are climbing exponentially. We're the only known source of extra CO2. The climate is measurably war... [More]

man may be helping it along, but we are not causing the climate to change. Nit picking. If because of human-caused activities, the temperature is 2 degrees warmer than it would otherwise have been, that's still man-caused warming. BTW: those climate models predict that without human involvement, we would now be in a cooling period, the mean global temperature having peaked about 2006. Doug

Can't you all just agree that climate changes happen naturally but man has made these changes more drastic with his continued pollution of his environment?

Can't you all just agree that climate changes happen naturally but man has made these changes more drastic with his continued pollution of his environment? 100 cement eldorado!

Can't you all just agree that climate changes happen naturally but man has made these changes more drastic with his continued pollution of his environment? No... i refuse to agree man has made things worse. i blame women.

Can't you all just agree that climate changes happen naturally but man has made these changes more drastic with his continued pollution of his environment? You have probably hit the nail on the head. That is exactly what I think. Now lets see if we can prove it. Doug

Can't you all just agree that climate changes happen naturally but man has made these changes more drastic with his continued pollution of his environment? Nothing to disagree with there, and I don't think many climate scientists would either. Br Cornelius

Humans are already down that road and sadly taking the animals with us. I wonder what will come first, Aliens or an unexplained asteroid? From afar, I'm watching the human race demolish itself. Not very interesting to watch but it suits me. I think we deserve it a little. Humans caused it.
