New Hampshire’s climate is changing. The frequency and intensity of extreme precipitation events is increasing and such a trend is consistent with indicators of climate change. According to a recent report, Climate Change in the Piscataqua/Great Bay Region: Past, Present, and Future (2011) climate change is already affecting the state in many ways. Temperatures, overall precipitation (especially in winter) and the frequency of extreme precipitation events are all rising. River discharge is increasing. Sea surface temperatures in the Gulf of Maine are rising, as is sea level.
The New Hampshire Seacoast has some very densely populated communities and they will be exposed to significant risks and challenges from these changes; risks to infrastructure, public health, natural resources, industry and overall quality of life. As these threats become more evident, so does the need to be proactive in protecting communities. (From the Clean Air Cool Planet Northeast Needs Assessment, 2011)
Being prepared for a changing climate includes many of the same steps required for communities to be better prepared for individual storms. Preparing for the effects of changing climatic conditions provides a head-start in preparing for the effects of individual storms. Take a look at Climate Resources for more information.
