Winters in northeastern North America have warmed faster than summers, with impacts on ecosystems and society. Global climate models (GCMs) indicate that winters will continue to warm and lose snow in the future, but uncertainty remains regarding the magnitude of warming. Here, we project future trends in winter indicators under lower and higher climate-warming scenarios based on emission levels across northeastern North America at a fine spatial scale (1/16°) relevant to climate-related decision making. Under both climate scenarios, winters continue to warm with coincident increases in days above freezing, decreases in days with snow cover, and fewer nights below freezing. …
Two Kinds Of Polar Knowledge, Lawrence C. Hamilton
Two Kinds Of Polar Knowledge, Lawrence C. Hamilton
Faculty Publications
Outreach and communication with the public have substantial value in polar research, in which studies often find changes of global importance that are happening far out of sight from the majority of people living at lower latitudes. Seeking evidence on the effectiveness of outreach programs, the U.S. National Science Foundation sponsored large-scale survey assessments before and after the International Polar Year in 2007/2008. Polar-knowledge questions have subsequently been tested and refined through other nationwide and regional surveys. More than a decade of such work has established that basic but fairly specific knowledge questions, with all answer choices sounding plausible but …

Sociopolitical Silos: Environmental Views And The Multiplicative Effect Of Same-Party Friends, Lawrence C. Hamilton, Joel Hartter, Curt Grimm
Faculty Publications
Analysis of climate and other environmental questions on three regional survey projects conducted over 2017–2020 (9,000+ interviews) elaborate on the well-known importance of political factors by adding support for three newer propositions. First, strength of political identification predicts climate-change views within the ranks of conservatives but not within ranks of liberals, evidence that conservatives’ climate-change views are more politically determined. Second, factor analysis suggests that climate-change beliefs meet statistical criteria for being an indicator of sociopolitical identity, alongside the traditional indicators of ideology and party, or the newer one of Trump support. This result calls for caution interpreting models that …
Generational Aspects Of U.S. Public Opinion On Renewable Energy And Climate Change, Lawrence C. Hamilton, Joel N. Hartter, Erin Bell
Generational Aspects Of U.S. Public Opinion On Renewable Energy And Climate Change, Lawrence C. Hamilton, Joel N. Hartter, Erin Bell
Sociology
The topics of climate change and renewable energy often are linked in policy discussions and scientific analysis, but public opinion on these topics exhibits both overlap and divergence. Although renewable energy has potentially broader acceptance than anthropogenic climate change, it can also sometimes face differently-based opposition. Analyses of U.S. and regional surveys, including time series of repeated surveys in New Hampshire (2010–2018) and northeast Oregon (2011–2018), explore the social bases of public views on both issues. Political divisions are prominent, although somewhat greater regarding climate change. Such divisions widen with education, an interaction effect documented in other studies as well. …

Economic Contributions Of Winter Sports In A Changing Climate, Hagenstad Consulting, Inc., Elizabeth Burakowski, Rebecca Hill
Earth Systems Research Center
In mountain towns across the United States that rely on winter tourism, snow is
currency. For snow lovers and the winter sports industry, predictions of a future with
warmer winters, reduced snowfall, and shorter snow seasons is inspiring them to
innovate, increase their own efforts to address emissions, and speak publicly on the
urgent need for action.
This report examines the economic contribution of winter snow sports tourism to
U.S. national and state-level economies. In a 2012 analysis, Protect Our Winters and
the Natural Resources Defense Council found that the winter sports tourism industry
generates $12.2 billion and 23 million …
The News You Choose: News Media Preferences Amplify Views On Climate Change, Jessica L. Bolin, Lawrence C. Hamilton
The News You Choose: News Media Preferences Amplify Views On Climate Change, Jessica L. Bolin, Lawrence C. Hamilton
Sociology
How do choices among information sources reinforce political differences on topics such as climate change? Environmental sociologists have observed large-scale and long-term impacts from news media and think-tank reports, while experimental science-communication studies detect more immediate effects from variations in supplied information. Applying generalized structural equation modeling to recent survey data, previous work is extended to show that political ideology, education and their interaction predict news media information choices in much the same way they predict opinions about climate change itself. Consequently, media information sources serve as intervening variables that can reinforce and, through their own independent effects, amplify existing …

Vegetation phenology is a sensitive indicator of climate change and has significant effects on the exchange of carbon, water, and energy between the terrestrial biosphere and the atmosphere. The Tibetan Plateau, the Earth's “third pole,” is a unique region for studying the long‐term trends in vegetation phenology in response to climate change because of the sensitivity of its alpine ecosystems to climate and its low‐level human disturbance. There has been a debate whether the trends in spring phenology over the Tibetan Plateau have been continuously advancing over the last two to three decades. In this study, we examine the trends …

Does It Matter If People Think Climate Change Is Human Caused?, Joel N. Hartter, Lawrence C. Hamilton, Angela E. Boag, Forrest R. Stevens, Mark J. Ducey, Nils D. Christoffersen, Paul T. Oester, Michael W. Palace
Sociology
There is a growing consensus that climate is changing, but beliefs about the causal factors vary widely among the general public. Current research shows that such causal beliefs are strongly influenced by cultural, political, and identity-driven views. We examined the influence that local perceptions have on the acceptance of basic facts about climate change. We also examined the connection to wildfire by local people. Two recent telephone surveys found that 37% (in 2011) and 46% (in 2014) of eastern Oregon (USA) respondents accept the scientific consensus that human activities are now changing the climate. Although most do not agree with …

Staying In Place During Times Of Change In Arctic Alaska: The Implications Of Attachment,Alternatives, And Buffering, Henry P. Huntington, Philip A. Loring, Glenna Gannon, Shari Fox Gearheard, S. Craig Gerlach, Lawrence C. Hamilton
Sociology
The relationship between stability and change in social-ecological systems has received considerable attention in recent years, including the expectation that significant environmental changes will drive observable consequences for individuals, communities, and populations. Migration, as one example of response to adverse economic or environmental changes, has been observed in many places, including parts of the Far North. In Arctic Alaska, a relative lack of demographic or migratory response to rapid environmental and other changes has been observed. To understand why Arctic Alaska appears different, we draw on the literature on environmentally driven migration, focusing on three mechanisms that could account for …

Flood Realities, Perceptions, And The Depth Of Divisions On Climate, Lawrence C. Hamilton, Cameron P. Wake, Joel N. Hartter, Thomas G. Safford, Alli J. Puchlopek
Sociology
Research has led to broad agreement among scientists that anthropogenic climate change is happening now and likely to worsen. In contrast to scientific agreement, US public views remain deeply divided, largely along ideological lines. Science communication has been neutralised in some arenas by intense counter-messaging, but as adverse climate impacts become manifest they might intervene more persuasively in local perceptions. We look for evidence of this occurring with regard to realities and perceptions of flooding in the northeastern US state of New Hampshire. Although precipitation and flood damage have increased, with ample news coverage, most residents do not see a …

Wildfire, Climate, And Perceptions In Northeast Oregon, Lawrence C. Hamilton, Joel N. Hartter, Barry D. Keim, Angela E. Boag, Michael W. Palace, Forrest R. Stevens, Mark J. Ducey
Sociology
Wildfire poses a rising threat in the western USA, fueled by synergies between historical fire suppression, changing land use, insects and disease, and shifts toward a drier, warmer climate. The rugged landscapes of northeast Oregon, with their historically forest- and resource-based economies, have been one of the areas affected. A 2011 survey found area residents highly concerned about fire and insect threats, but not about climate change. In 2014 we conducted a second survey that, to explore this apparent disconnect, included questions about past and future summertime (fire season) temperatures. Although regional temperatures have warmed in recent decades at twice …

Trust In Scientists On Climate Change And Vaccines, Lawrence C. Hamilton, Joel N. Hartter, Kei Saito
Sociology
On climate change and other topics, conservatives have taken positions at odds with a strong scientific consensus. Claims that this indicates a broad conservative distrust of science have been countered by assertions that while conservatives might oppose the scientific consensus on climate change or evolution, liberals oppose scientists on some other domains such as vaccines. Evidence for disproportionately liberal bias against science on vaccines has been largely anecdotal, however. Here, we test this proposition of opposite biases using 2014 survey data from Oregon and New Hampshire. Across vaccine as well as climate change questions on each of these two surveys, …

Climate warming is projected to affect forest water yields but the effects are expected to vary. We investigated how forest type and age affect water yield resilience to climate warming. To answer this question, we examined the variability in historical water yields at long-term experimental catchments across Canada and the United States over 5-year cool and warm periods. Using the theoretical framework of the Budyko curve, we calculated the effects of climate warming on the annual partitioning of precipitation (P) into evapotranspiration (ET) and water yield. Deviation (d) was defined as a catchment's change in actual ET divided by P …

EARTH’S CLIMATE CHANGES. It always has and always will. However, an extensive and growing body of scientific evidence indicates that human activities—including the burning of fossil fuel (coal, oil, and natural gas) for energy, clearing of forested lands for agriculture, and raising livestock—are now the primary force driving change in the Earth’s climate system. This report describes how the climate of northern New Hampshire has changed over the past century and how the future climate of the region will be affected by a warmer planet due to human activities.

A major achievement in research supported by the Kluane Lake Research Station was the recovery, in 2001 –02, of a suite of cores from the icefields of the central St. Elias Mountains, Yukon, by teams of researchers from Canada, the United States, and Japan. This project led to the development of parallel, long (103 – 104 year) ice-core records of climate and atmospheric change over an altitudinal range of more than 2 km, from the Eclipse Icefield (3017 m) to the ice-covered plateau of Mt. Logan (5340 m). These efforts built on earlier work recovering single ice cores in this …

Earth Sciences
Land-use change to meet 21st-century demands for food, fuel, and fiber will depend on many interactive factors, including global policies limiting anthropogenic climate change and realized improvements in agricultural productivity. Climate-change mitigation policies will alter the decision-making environment for land management, and changes in agricultural productivity will influence cultivated land expansion. We explore to what extent future increases in agricultural productivity might offset conversion of tropical forest lands to crop lands under a climate mitigation policy and a contrasting no-policy scenario in a global integrated assessment model. The Global Change Assessment Model is applied here to simulate a mitigation policy …

Long‐term data from the Hubbard Brook Experimental Forest in New Hampshire show that air temperature has increased by about 1 °C over the last half century. The warmer climate has caused significant declines in snow depth, snow water equivalent and snow cover duration. Paradoxically, it has been suggested that warmer air temperatures may result in colder soils and more soil frost, as warming leads to a reduction in snow cover insulating soils during winter. Hubbard Brook has one of the longest records of direct field measurements of soil frost in the United States. Historical records show no long‐term trends in …

The availability of nitrogen represents a key constraint on carbon cycling in terrestrial ecosystems, and it is largely in this capacity that the role of N in the Earth's climate system has been considered. Despite this, few studies have included continuous variation in plant N status as a driver of broad-scale carbon cycle analyses. This is partly because of uncertainties in how leaf-level physiological relationships scale to whole ecosystems and because methods for regional to continental detection of plant N concentrations have yet to be developed. Here, we show that ecosystem CO2 uptake capacity in temperate and boreal forests …

Indicators Of Climate Change In The Northeast 2005, Adam Markham, Cameron P. Wake
The Sustainability Institute Publications
Climate changes. It always has and always will. What is unique in modern times is that human activities are now a significant factor causing climate to change. This is evident in the recent rise in key greenhouse gases, such as carbon dioxide (CO2), in the atmosphere, and in the recent increase in global temperatures in the lower atmosphere and in the surface ocean.
The evidence presented in this report clearly illustrates that climate in New England is also changing. Over the past 100 years, and especially the last 30 years, all of the climate change indicators for the region reveal …

Over one‐third of the land area in the South Platte Basin of Colorado, Nebraska, and Wyoming, has been converted to croplands. Irrigated cropland now comprises 8% of the basin, while dry croplands make up 31%. We used the RHESSys model to compare the changes in plant productivity and vegetation‐related hydrological processes that occurred as a result of either land cover alteration or directional temperature changes (−2°C, +4°C). Land cover change exerted more control over annual plant productivity and water fluxes for converted grasslands, while the effect of temperature changes on productivity and water fluxes was stronger in the mountain vegetation. …
