Changes in vegetation shaped globaltemperatures over last 10,000 years wustl ScienceAdvances
Thompson had long been troubled by a problem with models of Earth's atmospheric temperatures since the last ice age. Too many of these simulations showed temperatures warming consistently over time.
But climate proxy records tell a different story. Many of those sources indicate a marked peak in global temperatures that occurred between 6,000 and 9,000 years ago. Thompson had a hunch that the models could be overlooking the role of changes in vegetation in favor of impacts from atmospheric carbon dioxide concentrations or ice cover."But previous models only show a limited amount of vegetation growth," he said."So, even though some of these other simulations have included dynamic vegetation, it wasn't nearly enough of a vegetation shift to account for what the pollen records suggest.
"Expanded vegetation during the Holocene warmed the globe by as much as 1.5 degrees Fahrenheit," Thompson said."Our new simulations align closely with paleoclimate proxies. So this is exciting that we can point to Northern Hemisphere vegetation as one potential factor that allows us to resolve the controversial
