PennFuture is hosting a Twitter chat with renowned Penn State climate scientist (and our good friend!) Michael Mann aka @MichaelEMann on Wednesday, September 17, from 2pm-3pm EDT. Use the hashtag #AskDrMann to participate. You won't wanna miss it!

Mann has been at the forefront of the climate change conversation over the past decade, from his widely-recognized research to his many media appearances explaining the science behind global warming.

He recently penned an op-ed in the Allentown Morning Call, where he urged the public to become more involved in the climate debate, and called on policymakers to regulate both carbon dioxide and methane -- greenhouse gases that are accelerating climate change.
