Two years later,the results did not.But then why doesnt life increasingly emerge on Earth as our temperatures get warmer?
While the switch may prompt some to assert that climate change is not hazardous to living creatures,Mayhew explained that the timescales in his teams study are huge--over 500million years--and therefore inappropriate for the shorter periods that we might look at as humans concerned about global wanning.Many global warming concerns are focused on the next century.He saidand the lifetime of a species is typically one to 10 million years.
I do worry that these findings vill be used by the climate skeptic community to saylook.Climate warming is fine。he said.Not to mention the numerous other things we seem to do to create a storm of threats to biodiversitythink of what habitat(栖息地)destruction,overfishing,and pollution can do for a speciesviability(生存力).Those things,Mayhew explained,give the organisms a far greater challenge in coping with climate change than they would have had in the absence of humans.
If we were to relax all these pressures on biodiversity and allow the world to recover over millions of years in a warmer climate.then my prediction is it would be an improvement in biodiversity,he said.So it looks like we need to curb our reckless treatment of the planet first,if we want to eventually see a surge in the number of species on the planet as temperatures get warmer.We dont have 500 million years to wait.
