PurposeThe purpose of this paper is to discuss the recent history of climate action planning at the University of New Hampshire (UNH), a public university with a long history of sustainability action and commitment. Items discussed include a partnership with Clean Air‐Cool Planet (CA‐CP) to produce a greenhouse gas (GHG) inventory tool that adapted national and international inventory methodologies to the unique scale and character of a university community; involvement of administrators, faculty, staff and students in climate action planning, including to meet the requirements of the American College & University Presidents' Climate Commitment (ACUPCC); and the role of climate action planning within a broader institutional goal of integrating sustainability across curricula, operations, research and engagement efforts.Design/methodology/approachBackground and historical information is shared in terms of best practices and lessons learned.FindingsSuccessful climate action planning includes campus‐wide stakeholder involvement, an institution‐wide commitment to sustainability, and careful planning and partnerships that tie into a higher education institution's educational mission and identity and that take into account the culture and sense of place of each institution.Practical implicationsThe paper contains lessons learned and best practices from which other institutions of higher education might learn.Originality/valueUNH, a recognized national leader in sustainability and climate protection, and CA‐CP developed one of the first emissions inventory tools for higher education in the USA. The tool has been adopted by more than 1,000 campuses and was adopted by the ACUPCC as the recommended tool for campuses not already participating in another GHG inventorying program. Instead of recreating the wheel, campuses may be able to learn from UNH and CA‐CP's climate planning experience and history.

We evaluate the relative desirability of alternative futures for the upper Merrimack River watershed in New Hampshire, USA based on the value of ecosystem services at the end of the 21st century as gauged by its present-day inhabitants. This evaluation is accomplished by integrating land-use and socioeconomic scenarios, downscaled climate projections, biogeophysical simulation models, and the results of a citizen-stakeholder deliberative multicriteria evaluation. We find that although there are some trade-offs between alternative plausible futures, for the most part, it can be expected that future inhabitants of the watershed will be most satisfied if land-use planning in the intervening years prioritizes water supply and flood protection as well as maintenance of existing farmland and forest cover. With respect to climate change, it is expected that future watershed inhabitants will be more negatively affected by the projected loss of snow cover than the anticipated increase in hot summer days. More important than the specific results for the upper Merrimack River watershed, this integrative assessment demonstrates the complex yet ultimately informative potential to link stakeholder engagement with scenario generation, ecosystem models, and multiattribute evaluation for informing regional-scale planning and decision making.

The papers in this Special Issue are the primary technical underpinnings for the Northeast Climate Impacts Assessment (NECIA), an integrated regional-scale assessment of projected climate change, impacts and options for mitigation and adaptation across the US Northeast. The consequences of future pathways of greenhouse gas emissions on projected climate and impacts across climate-sensitive sectors is assessed by using downscaled projections from three global climate models under both higher (Alfi) and lower (B1) emissions scenarios. The findings illustrate that near-term reductions in emissions can greatly reduce the extent and severity of regionally important impacts on natural and managed ecosystems and public health in the latter half of this century, and increase the feasibility that those impacts which are now unavoidable can be successfully managed through adaptation.

AbstractClimate change is altering the timing and duration of the vernal window, a period that marks the end of winter and the start of the growing season when rapid transitions in ecosystem energy, water, nutrient, and carbon dynamics take place. Research on this period typically captures only a portion of the ecosystem in transition and focuses largely on the dates by which the system wakes up. Previous work has not addressed lags between transitions that represent delays in energy, water, nutrient, and carbon flows. The objectives of this study were to establish the sequence of physical and biogeochemical transitions and lags during the vernal window period and to understand how climate change may alter them. We synthesized observations from a statewide sensor network in New Hampshire,USA, that concurrently monitored climate, snow, soils, and streams over a three‐year period and supplemented these observations with climate reanalysis data, snow data assimilation model output, and satellite spectral data. We found that some of the transitions that occurred within the vernal window were sequential, with air temperatures warming prior to snow melt, which preceded forest canopy closure. Other transitions were simultaneous with one another and had zero‐length lags, such as snowpack disappearance, rapid soil warming, and peak stream discharge. We modeled lags as a function of both winter coldness and snow depth, both of which are expected to decline with climate change. Warmer winters with less snow resulted in longer lags and a more protracted vernal window. This lengthening of individual lags and of the entire vernal window carries important consequences for the thermodynamics and biogeochemistry of ecosystems, both during the winter‐to‐spring transition and throughout the rest of the year.
