Q: How are policy makers, journalists and the public, who are not scientists, supposed to filter out who’s right and who’s wrong?Singer also says "there has been no rise in temperature for some 17 years," which is downright false: HadCRUT4 shows 0.11 ± 0.06 °C of warming over the last 17.0 years (uncertainty is 2σ calculated via OLS). GISS data has it at 0.15 ± 0.06 °C.
Singer: The IPCC has a way of ignoring inconvenient facts. It’s actually fraudulent but we don’t like to use that term, not because we’re scared of being sued but because all it does it get the other side’s back up.
Of course, it's also false because it ignores the strong ocean warming over that time.
There's also this bit of obfuscation:
Singer: Well, it depends on where you start. If you start from the last ice age, 18,000 years ago, it certainly is much warmer. If you start 1,000 years ago, from the medieval climate warming, then it’s slightly cooler. If you start from the (Middle) Ice Age or let’s say around 1700 or so, then it is definitely warmer. So it has been warming. The earth is warming, not steadily, but in jumps.When historians of the year 2200 write the history of climate change, is anyone going to come out worse than Fred Singer?
