Human hunters off the hook? Climate change caused wooly mammoths' extinction, say scientists.
Uh huh. So how do they know this?
Climate change, rather than human hunters, drove the wooly mammoth to extinction. That’s the claim from scientists who say that the hairy beasts lost their grazing grounds as forests rapidly replaced grasslands after the last ice age, roughly 20,000 years ago. The researchers used palaeoclimate and vegetation models to simulate the plant cover across the mammoths’ habitat around that time.
Yes folks, it's a modelling study. Another one. From the paper's abstract, the researchers took output from the Hadley Centre's Unified Climate Model and pumped it into another model which purports to simulate how a variety of plants react to temperature changes. So even if the vegetation model works it still relies on the Hadley Centre model being something one can rely on. Is it just me that finds this all rather unconvincing. I mean is the Hadley Centre Unified Model something you'd want to bet the house on?
Well, according to this article, the Unified Model is:
"the same model that is used to produce every weather forecast you see on British terrestrial television."
