“Paleo-clamatology“. Anthony Watts disparages scientific studies until he finds one that suits him. Incomplete data, cherry-picking, needs confirmation, wait for new data, they “don’t share”, whatever he can come up with to brush inconvenient research aside. But if he likes the conclusion the paper is immediately the Holy Grail.
In the case of this report from Nature about oxygen-18 isotopes in molluscs as paleoclimate indicators, Anthony thinks it will “surely stick in the craw of many who think we are living in unprecedented times of warmth“. He also ‘cautiously’ declares “the data resolution is incredible.” Good skepticism there, Anthony.
Now this kind of data is very interesting. It will be exciting to watch the study’s reception by knowledgeable scientists and how it develops under further scrutiny and deeper analysis. I hope to hear a lot more about it.
But a few things stick out in the context of Anthony’s praise: First, the data is from a single Icelandic bay. Not a global signal. Second, the author says “What we’re getting to here is palaeoweather.” Weather ain’t climate, right Anthony? Third, the presented data stops at 1600 AD, well before reliable direct temperature measurements were available or the onset of what some people call Global Warming.
I bet Dr. William Patterson is about to find he has some creepy new friends that will be hard to shake.
