It's what we're doing with the by products. We dig all the goodness out of the earth and don't replenish it. We litter our oceans with rubbish, poisons and plastics. Even Russia was or is dumping all their nuclear waste into the sea. Daily we're stripping global forests in order to make way for industry and with all the Co2 being emitted - are there are enough plants and trees to absorb it all.As the Arctic warms up and sea ice coverage decreases the Suns heat falls on dark water which absorbs it rather than on white ice/snow which largely reflects it global warming increases. Likewise frozen tundra thawing will also emit much CO2. These tipping points are of major concern to those who know this stuff. IPCC predictions are always exceeded.
and they are? Im still cautiously sceptical of the whole thing and Im not sure humans can stuff up a planet "all by themselves"...we were born with socalled superior brains and were expected to evolve in the ways in which we have..the higher intelligence that put us here would not have allowed such a dangerous toy to fall into such ignorant hands.. we are only using by pruducts of earth after all..thats like saying having our own blood returned to us during a transfusion is poisonous and will kill us
I'm still not sure on this global warming panic - but we do need to start cleaning up in a big way and disposing of our wastes and poisons properly, driving less and planting more trees.
We need less people. Perhaps all the natural disasters that are ahead of us will help clean the planet up a bit and eliminate a few of us.
