David Burton @wattsupwiththat denies what's really warming the world

If you've been around climate stuff these last few days you may well have come across a neat climate graphic at Bloomberg. Eric Roston and Blacki Migliozzi, with help from Kate Marvel and Gavin Schmidt, have charts of global surface temperatures and more. What their charts show are the various contributions to global surface temperature changes since 1880, modeled and observed. There are a number of different charts illustrating the observed annual mean global surface temperature against modeled, as affected by:

1. Natural factors:

• orbital changes only
• solar variation
• volcanic eruptions
• all three natural factors together.

2. Human activity:

• land use changes
• ozone changes
• aerosols
• greenhouse gas accumulation
• all human activity together.

3. Natural factors and human activity combined.

The graphic is worth bookmarking for showing to (normal) people to illustrate how human activity has led to the large rise in global surface temperatures since 1880. There's not much point showing it to deniers, the sort of people who relish articles like the one by David Burton at WUWT the other day (archived here).

You might remember David. He's the chap who spent 547.5 days and nights fretting about Doran & Zimmerman (2009) before coming up with a number-fudging brainwave (It was not a brainwave, it was nothing but Dave's bad arithmetic.)

Denier Weirdness: David Burton @wattsupwiththat finally has a 97% brain wave!

If you haven't realised by now, one of the things that keeps fake sceptics awake at night is trying to figure out ways to reject the fact that climate science shows that humans are causing global warming.

Yesterday on WUWT one fake sceptic, David Burton, published a long article (archived here) telling us how for the last year and a half, he's been thinking of how to protest the Doran and Zimmerman paper, published almost five years ago.
