Pennsylvania has released an updated report on how future climate change may impact the state, about 18 months after it was due.

Marc McDill, a Penn State University forestry expert who worked on the report, says the evidence is "very, very strong" that Pennsylvania's climate is going to change significantly. McDill says that by 2100 the climate here will probably be more like what Georgia is now.

The report says that greenhouse gases from humans are mostly to blame for temperatures that have already climbed since about 1950.

The report finds there could be significant impacts to Pennsylvania wildlife, rivers, lakes, and aquatic ecosystems, but that economic impacts are likely to be focused on certain industries, with a small effect on the overall economy and to public health.
