I'm most impressed that you are so confident that man's influence on climate is a myth - for at least 20 years it's been occupying an awful lot of very brilliant minds and taking a heck of a lot of computer time, satellite observations and ice core expeditions.
I'll ring around and tell them all to go home, that you've got it sussed an that your Nobel prize is in the post!
I would largely ignore the second last article also.
What annoys me the most are the words 'predict climate'. We know far too little about climate and the environment to play Ini Mini Miny Mo and on the basis of that result declare that it is "a more serious threat to national security than al-Qaeda". That is just irresponsible.
Gammaray, you are right to question the Man's envolvement in Global Warming, yet wrong to dismiss it. The fact that there is very little proof of its effect does not mean we are blameless. Science should consider all of the variables and we are one of those. Our actions bare consequences, it's just nobody knows what they are or how to distinguish them from what would happen if we were not involved.
Considering historical climate shifts we are just about on the brink of a new ice age, so all this might just be a normal process. Our influence however, might either speed it up or slow it down or perhaps affect its' course.
Either way it is unavoidable.
S.
Gammaray you said 15000 years ago most of Europe was sub-tropical.
I'm telling you it was in an ice age!
Did it ever occur to you that climate change might just be a tad more complex than saying "We've seen big changes in the past therefore it can't be man's influence?"
It may be that it isn't but it may also be that it is. In the few days after 9/11 there was an observed change in the opposite direction http://en.wikipedia.org/wiki/Global_dimming
Which strongly implies that human activity can have an impact.
Which ever way you look at it the following are widely agreed:
1/ The Earth's climate is warming rapidly
2/ Carbon in the atmosphere is at it's highest level for thousands of years
3/ Carbon emissions heat the atmosphere
4/ Humans create carbon emission
I think it's fair to say the planets getting hotter and we're not helping!
Ooop,s pressed the wrong button.
Continued.
In fact some areas are not experiencing any warming, where as others are cooling.
Atmospheric gases change constantly, and although carbon emmisions have increased the atmospheric warming can not be atributed solely to that.
The persentage of carbon emmisions in the atmospher is still increadibly low. Most of the damage is done by land use.
Still the point remains that these changes are natural in the Earths evolution, whether we like it or not.
