Heavy rains. Less snow. Up to 60 days of extreme heat, every year by the end of the century. New Hampshire’s 2021 climate assessment, released Wednesday, paints a grim picture of the state’s future, unless greenhouse gas emissions are reduced.
New projections show sea levels on the East Coast could rise about a foot in the next 30 years. They sharpen the focus on what a wetter future could look like on New Hampshire’s Seacoast.
New Hampshire experienced more days over 90 degrees and higher average and overnight temperatures in the summers over the past 50 years, as human activity.
Even if countries cut greenhouse gas emissions immediately, New Hampshire will get warmer and wetter within the next three decades, and towns need to plan.
