You do realize that CO2 is REQUIRED in the atmosphere. The absorption rate compared to the naturally produced rate is showing me that nature seems to be taking care of the extra CO2 we have put out.
Do you have any fancy charts like this showing how much CO2 was absorbed when we had no impact on the earth? Did you know 2 3/4th million years ago the climate was hotter, had higher sea levels and higher levels of CO2 then now?
Yes I did as I pointed out earlier it is thought by some that our lungs developed in a much higher concn of CO2 and that this is the root of quite a few ailments of the modern age...This is behind the attempts to diagnose health by breath analysis... In roman britian we were a wine producing nation. Grapes havent grown here for hundreds of years, but now again on the south coast, they can be harvested...The table above shows what an ENORMOUS amount of CO2 the world absorbs, and as you point out needs to absorb...If our emissions were half our 1995 level it would appear the earth would deal with it for us, in terms of CO2 anyway...
Climate shifts whether we are here or not. Blaming something that occurs naturally on humans is basically a way of saying "We are god, we change the earth for the better or the worse" when really we have nothing but the slightest hand in this.
The world cares very little wether the climate changes or not, life will go on. If it gets too hot the lizards will take over again! The question is wether or not we want to keep ourselves living here for a little longer or not...nature will get along fine without us.
The second point is that the problem is not so much that the climates is changing, but the speed at which its changing. It has prob never changed so quickly, this is what causes the real problems as species dont have time to move to other areas as their habitat warms up or cools down...often even if they could move they cant cause we have built a city in the way...
We are currently in an inter-glacial period and this will last a couple million years maybe less maybe more, but all this global warming talk is just people being paranoid. People think it gets hotter every summer, so they check out weather history and see the average temperatures are getting warmer, but its just normal temperature fluctuation. Its like flipping a quarter. Its not always going to be 50/50 heads tails. You may end up with more heads sometimes you may end up with more tails.
Its not as simple as flipping of coin though, because there IS a little heating up occurring, that was just to show temperature fluctuations as a possible cause for the average temperature being 1-2 degrees warmer ]over the last 150 years.
Possible, but highly unlikely....given the concequences we face, surely it is better we act to limit emissions, and then find out in 100yrs that we were wrong in our assumptions and you get to laugh at us, as a pose to not doing anything and finding out we were right and us not being able to laugh at you very much cause we are starving cause all our crops have failed...thats very selfish of you to load the bet in your favour like that!
If you want to base global warming off of ice cores, then let me tell you, the planet has ALWAYS warmed up in between and before ice ages. That is if the ice cores are as accurate as people think they are.
In between the ice ages it has, but never so fast, also it is thought that we should be entering an iceage rather than warming up...I'll look for some temp data later...
There is really no proof to man made global warming that can't be proven to be false or really what nature is intending to happen.
There is lots...how else can you explain the elevated CO2 level in the air...where has it come from, saying that is like soaking your garden with a hose saying you cant PROVE 100% that this water on my lawn isnt natural...fact CO2 pours out the end of your car, our powerstations and a myriad of other sources...unless you manage to discover some ENORMOUS outpouring of CO2 from natural sources that the 1000's of scientists and billions of dollars has been spent trying to find, your on to a losser with that one!!!
One of the few ways i can think of that we COULD alter climate dramatically is by Nuclear Winter, which i believe is much more possible to happen then man made global warming.
With this we can agree, but that is a discussion for another thread...but I bet that thread just gets nasty...
