Björn Lomborg: Oliver Tickell has abandoned his climate change argument

Oliver Tickell defends against my critique his visions of 4C leading to a catastrophic future. Two casual observations lend themselves readily. First, Tickell has entirely abstained from defending his claim for human extinction from 4C. Thanks. Second, I was clearly wrong when I said that Tickell's claim for 70-80 metres of sea level rise had maxed out campaigners' scare potential because that means all ice is melted. Showing an amazing ability to raise the stakes none the less, Tickell now talks about sea level going 100m higher.

The UN climate panel (IPCC) says that 4C will lead to a rise a hundredth of that figure; but Tickell simply claims such moderate projections are "dangerously misplaced". All I can see is that such facts are terribly inconvenient.

Nonsensical Noise or Solar Signal?

[CO2 Science] The two researchers thus conclude that "the sun is influencing climate significantly more than the IPCC report claims," and that "the current anthropogenic contribution to global warming is significantly over-estimated." In fact, citing Scafetta and West (2007), they go on to say they "estimate that the sun could account for as much as 69% of the increase in earth's average temperature, depending on the TSI reconstruction used."
