The dinosaurs flourished in a very warm climatic period and were both cold-blooded and VERY large. But you would never guess that from the effusions of the alleged scientist below. According to him they should have been about the size of mice.
And this crap was published in "New Scientist". But "New Warmist" has been a better name for that publication for some time now
It is well established that cold-blooded species get smaller as the climate heats up, says Andrew Hirst of Queen Mary, University of London. Experiments show that, on average, 1 °C of warming reduces their adult body mass by 2.5 per cent. The mystery is why.
To find out, Hirst pulled together data on 15 species of copepod that swim in the open sea, focusing on how they grew at different temperatures. As temperatures rose, the copepods got heavier faster. Hirst thinks that's because physiological reactions accelerate at warmer temperatures, allowing the copepods to bulk up faster.
But they also matured to adulthood faster, so their rapid growth ground to a halt at a young age. The overall effect was such that the warmer copepods wound up smaller.
It's not clear why temperature has such a strong effect on the way these organisms mature, but Hirst suspects evolution favours organisms that are flexible in how fast they mature to adulthood. In a competitive environment, this increases the odds that individuals will reproduce before they are killed.
