Arguments Against Both Climate Change and Overkill
Detractors have asserted that neither the overkill nor climate change hypotheses can explain several observations. Among these are the observation that browsers, mixed feeders and non-ruminant grazer species suffered most, while ruminant grazers generally survive However a broader variation of the overkill hypothesis may predict this, because changes in vegetation wrought by anthropogenic fire preferentially selects against browse species. Because of perceived shortcomings of the overkill or climate change hypotheses alone, some scientists support a combination of climate change and overkill.

Famous quotes containing the words arguments, climate and/or change:
“It has often been argued that absolute scepticism is self-contradictory; but this is a mistake: and even if it were not so, it would be no argument against the absolute sceptic, inasmuch as he does not admit that no contradictory propositions are true. Indeed, it would be impossible to move such a man, for his scepticism consists in considering every argument and never deciding upon its validity; he would, therefore, act in this way in reference to the arguments brought against him.”
—Charles Sanders Peirce (1839–1914)
“The climate of Ohio is perfect, considered as the home of an ideal republican people. Climate has much to do with national character.... A climate which permits labor out-of-doors every month in the year and which requires industry to secure comfort—to provide food, shelter, clothing, fuel, etc.—is the very climate which secures the highest civilization.”
—Rutherford Birchard Hayes (1822–1893)
“The most conservative man in the world is the British Trade Unionist when you want to change him.”
—Ernest Bevin (1881–1951)
