[MCN] Climate models wrong again, & in the usual direction

[Lance Olsen]

Public Release: 22-Jan-2018
New Eocene fossil data suggest climate models may underestimate future polar warming
FLORIDA MUSEUM OF NATURAL HISTORY
A new international analysis of marine fossils shows that warming of the polar oceans during the Eocene, a greenhouse period that provides a glimpse of Earth's potential future climate, was greater than previously thought.

Excerpt from release

"Yes, the tropics are warming but nowhere near to the same degree as the polar regions," Evans said. "That's something we really need to be able to understand and replicate in climate models. The fact that many models are unable to do that at the moment is worrying."

“The impacts of temperature may also be more indirect, but still related to physiological tolerances. 
For example, in spiny lizards (Sceloporus), local extinctions seem to occur because higher temperatures 
restrict surface activity during the spring breeding season to a daily time window that is overly short [23]. 

Similarly, increased air temperatures may both decrease activity time and increase energy maintenance costs, 
leading organisms to die from starvation rather than from overheating [14].”
