Like you, I'd have thought that most of today's plants have evolved to suit today's climate and atmosphere (and soil conditions). And I'd say all agricultural species have been developed for yesterday's climate (wheat, corn, barley, horticulture etc). <br /><br />It's only now that plant breeders (and animal breeders) are working out how to select for the new climate, whether its drought resistance or ability to survive water-logging or maintain protein content despite growth spurts or resistance to mildew and rust etc (and for lower methane production re the animals).<br /><br />As you say, it all gets very complicated for the food web if some plants flower at the wrong time for the pollinators.Souhttps://www.blogger.com/profile/08818999735123752034noreply@blogger.comtag:blogger.com,1999:blog-2313427464944392482.post-22853961358708000812013-07-18T04:30:09.629+10:002013-07-18T04:30:09.629+10:00I note that Ed repeats the CO2 is plant food there...I note that Ed repeats the CO2 is plant food therefore beneficial meme. There is surely more to it than that. Most modern plants probably evolved at a time of lower CO2 levels and there are all sorts of co-evolutionary matters that need to be taken into consideration (eg if the pollinators cannot adapt to a warming world it won't matter how much the CO2 promotes plant growth for example).Catmandohttps://www.blogger.com/profile/12313870265499015076noreply@blogger.com
