You've provided no evidence or hard facts to back your claim that the current warming is largely or even equally natural. Only an argument and opinions.
you know I can't quite get whether you just have no ability to understand what I say or just choose to ignore it.
I have never claimed current warming is largely or equally natural variance, or CO2 driven or anything else. Thats what you keep saying I have said, when I have not. My point is that the correllation with CO2 levels and global warming is not that strong as the warming trend was in place well before the CO2 levels were high enough to have an effect.
All I have done is provided evidence that the current warming trend started around 200years ago and is still continuing and that natural trend can't be dismissed as having no ongoing effect.
I will make it clear for you....the level of contribution of CO2 to current observed warming is not known. NOT KNOWN..... IS NOT KNOWN BY ANYONE.....IS A SOURCE OF SIGNIFICANT DEBATE BY SCIENTISTS....ALL CLAIMS OTHERWISE ARE THEORY ONLY (ON BOTH SIDES OF THE ARGUMENT)
Regarding your graph, im not sure what that means, it no secret or even debated that CO2 levels have risen and are currently 30% higher than at any time in the recent past (from your graph).....if you are trying to suggest that CO2 emmissions from 1800 created a strong warming trend immediately that has continued at the same rate since then, I think you had better find some backup for that, because I don't think anyone disputes that the influence of CO2 on warming was miminal until mid 1900's.
