Rising Temperatures May, Or May Not, Affect Biodiversity

The effects of temperature changes may be a big deal, overstated, or mitigated by evolution, say stubbornly scientific scientists

A volley of studies into the likely effects of climate change on various animal species - and thus on biodiversity worldwide - have come out in the last few days. The headliner, examining butterflies in Massachusetts, seems to indicate that rising temperatures are having powerful ecological effects: but another pair of studies showed that other factors may be more powerful than warming, and yet another appears to indicate that dangers are being overblown.
