Good source of climate change data

[popeyespappy]

I fail to see how. I'm merely responding to a facetious statement with sarcasm. Do I really need to put a smiley after every statement I submit? I disgress, I'll ask you an honest question, how do you differentiate between a natural climate change trend and a trend induced by anthropogenic climate change?

Your sarcastic remark to the comment I made to another forum member amounted to an accusation of lying about having read articles by anthropogenic global warming skeptics. The fact is I have investigated many skeptical claims. When I am presented with a claim about global warming I ask questions. What is the source of the claim? What is the evidence that the claim is true? What is the evidence that it is not?

Asking these questions is why I know that there is a large body of empirical evidence in support of anthropogenic global warming. It’s why I know that in the last 30 years there has been no correlation between solar irradiance or cosmic rays and global temperatures. And it is why I know that despite the IPCC’s inclusion of a non peer reviewed statement about Himalayan glacier melt that Himalayan glaciers are in fact receding at an accelerating rate.



I differentiate between a natural climate change trend and a trend induced by anthropogenic causes based on the currently available evidence. The climate responds to forcing. It doesn’t make a difference to the climate if the forcing is natural or caused by humans. The evidence tells us the forcing that drove historical climate change was natural in origin. It also tells us that the forcing driving the current warming trend is anthropogenic CO2.
