    Nature Conservancy Scientist Nels Johnson says climate change will come in many forms, from major flooding to intense heat.

    Johnson: Today Philadelphia sees 20 days of 90 degrees or warmer. Under some of the climate change scenarios the more extreme ones especially if don’t really do much to control emissions over the next several decades we could be seeing as many as 70 or more days of 90 degrees.

    Johnson says increased temperatures and floods need to be taken into consideration when building bridges and storm drainage systems. He adds working on cutting down on carbon emissions from fossil fuels could help delay the effects of climate change.
