You realize Todd is pushing LeDupester's nonsense at you? Read his post #511. Todd doesn't need you to explain this to him.

Hauke, you are correct. Numerous plant and animal species are moving outside their normal ranges in response to rising temperatures. That has disturbed large number of biological cycles and predator-prey relationships. Do not be concerned about Westwall giving you grief. Nor SSDD, jc456, Crusader Frank, LaDexter or a dozen other deniers here. They are all fools still fretting about Al Gore and communist conspiracies.
Really? Then providing links to actual empirical observations shouldn't be a problem for you to provide. Please do so.
