Are New Hampshire’S Winters Warming? Yes, But Fewer Than Half Of State Residents Recognize The Trend, Lawrence C. Hamilton, Elizabeth Burakowski

The Carsey School of Public Policy at the Scholars' Repository

In this brief, authors Elizabeth Burakowski and Lawrence Hamilton review some basic evidence about winter warming in New Hampshire, explore to what extent state residents are aware of this trend, and ask who is aware, in terms of characteristics such as age, education, or participation in winter sports. Results from two statewide surveys find limited awareness of the trend overall, and no significant differences by age, education, or winter sports participation. Instead, perceptions of this winter trend depend on political identity: conservatives are much less likely than other groups to recognize that warming has occurred.

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 …

Salt Marsh Values In A Changing World: Examining Sea Level Rise On Tidal Marshes With A Surface Elevation Table, Sarah Martina Tierney

Student Research Projects

Rising seas are threatening coastal communities and putting added pressures on the natural environment. Sea level rise rates are increasing on a global scale (from 1.7 to 3.2 mm/yr). Salt marshes are not only intertidal habitats acutely influenced by sea levels, but they also provide key ecosystem services such as: buffers against storm surges, habitat for wildlife, carbon dioxide storage, and pollutant filtration. In New England, salt marshes have built at a rate of 1 to 2 mm annually over the past 4,000 years, which has kept pace with sea level rise. However, we do not know if salt marshes …

Public Knowledge About Polar Regions Increases While Concerns Remain Unchanged, Lawrence C. Hamilton, Matthew J. Cutler, Andrew P. Schaefer

The Carsey School of Public Policy at the Scholars' Repository

The authors of this brief conduct the first comparative analysis of the polar questions that were part of the National Opinion Research Center's 2006 and 2010 General Social Survey. Developed by scientists at the National Science Foundation's Office of Polar Programs, these questions covered topics such as climate change, melting ice and rising sea levels, and species extinction. The authors report that the public's knowledge about the north and south polar regions significantly improved between 2006 and 2010--before and after the International Polar Year. In addition, respondents who know more about science in general, and polar facts specifically, tend to …

The New Hampshire Greenhouse Gas Emissions Reduction Fund: Year 3 (July 2011-June 2012) Evaluation, Matthew Magnusson, Cameron P. Wake

The Sustainability Institute Publications

The Greenhouse Gas Emissions Reduction Fund (GHGERF) was created by the New Hampshire legislature in 2008 and has been administered by the New Hampshire Public Utilities Commission (PUC). The purpose of the Fund was to support energy efficiency, energy conservation, and demand response programs to reduce New Hampshire’s greenhouse gas emissions. Funding was derived from the State’s participation in the Regional Greenhouse Gas Initiative (RGGI), a cooperative effort by nine northeastern states to reduce carbon dioxide emissions in the electric power sector via a cap and trade program. As of June 2012, RGGI auctions have resulted in revenues to New …

Do You Believe The Climate Is Changing? Answers From New Survey Research, Lawrence C. Hamilton

The Carsey School of Public Policy at the Scholars' Repository

This brief explores how political views influence Americans’ understanding and perception of science. The research is based on a national version of the Community and Environment in Rural America survey called NCERA, and on New Hampshire’s statewide Granite State Poll. Author Lawrence Hamilton reports that most people on both surveys feel that they understand either a great deal or a moderate amount about global warming or climate change. However, deep partisan divisions affect both personal beliefs about climate change and perceptions of agreement among scientists. Democrats are much more likely to state they believe that climate change is happening, caused …

The Sustainability Institute Publications

Earth ’s climate changes. It always has and always will. However, an extensive body of scientific evidence indicates that human activities are now a significant force driving change in the Earth’s climate system. This report describes how the climate of the Piscataqua/Great Bay region of coastal New Hampshire in the United States has changed over the past century and how the future climate of the region will be affected by human activities that are warming the planet.

Overall, the region has been getting warmer and wetter over the last century, and the rate of change has increased over the last …

Climate Change: Partisanship, Understanding, And Public Opinion, Lawrence C. Hamilton

The Carsey School of Public Policy at the Scholars' Repository

In 2010, Carsey Institute researchers began including three new questions about climate change on a series of regional surveys. They asked how much people understand about the issue of global warming or climate change; whether they think that most scientists agree that climate change is happening now as a result of human activities; and what they believe personally about the topic. Survey results show that while large majorities agree that climate change is happening now, they split on whether this is attributed mainly to human or natural causes. Brief author Lawrence Hamilton concludes that most people gather information about climate …

A 700 Year Record Of Southern Hemisphere Extratropical Climate Variability, Paul A. Mayewski, Kirk A. Maasch, James W.C. White, Eric J. Steig, E A. Meyerson, Ian D. Goodwin, Vin Morgan, Tas D. Van Ommen, Mark Aj Curran, Joseph M. Souney Jr, K Kreutz

Earth Systems Research Center

Annually dated ice cores from West and East Antarctica provide proxies for past changes in atmospheric circulation over Antarctica and portions of the Southern Ocean, temperature in coastal West and East Antarctica, and the frequency of South Polar penetration of El Niño events. During the period AD 1700–1850, atmospheric circulation over the Antarctic and at least portions of the Southern Hemisphere underwent a mode switch departing from the out-of-phase alternation of multi-decadal long phases of EOF1 and EOF2 modes of the 850 hPa field over the Southern Hemisphere (as defined in the recent record by Thompson and Wallace, 2000; Thompson …

A 700-Year Record Of Atmospheric Circulation Developed From The Law Dome Ice Core, East Antarctica, Joseph M. Souney Jr, Paul A. Mayewski, Ian D. Goodwin, David Meeker, Vin Morgan, Mark Aj Curran, Tas D. Van Ommen, Anne S. Palmer

Earth Systems Research Center

A 700-year, high-resolution, multivariate ice core record from Dome Summit South (DSS) (66°46′S, 112°48′E; 1370 m), Law Dome, is used to investigate sea level pressure (SLP) variability in the region of East Antarctica. Empirical orthogonal function (EOF) analysis reveals that the first EOF (LDEOF1) of the combined glaciochemical, oxygen isotope ratio, and accumulation rate record from DSS represents most of the variability in sea salt seen in the record. LDEOF1 is positively correlated (at least 95% confidence level) to instrumental June mean SLP across most of East Antarctica. Over the last 700 years, LDEOF1 levels at Law Dome were the …
