Climate change mitigation

1. Geophysical potential for wind energy over the open oceans

"Wind speeds over open ocean areas are often higher than those in the windiest areas over land, which has motivated a quest to develop technologies that could harvest wind energy in deep water environments. However, it remains unclear whether these open ocean wind speeds are higher because of lack of surface drag or whether a greater downward transport of kinetic energy may be sustained in open ocean environments. Focusing on the North Atlantic region, we provide evidence that there is potential for greater downward transport of kinetic energy in the overlying atmosphere. As a result, wind power generation over some ocean areas can exceed power generation on land by a factor of three or more."

2. Public receptiveness of vertical axis wind turbines

"We find that the visual differences between the vertical and conventional wind turbines did not matter very much in any of the hypothetical settings in which we placed them. However, the prospect of killing fewer birds registered strongly with our survey respondents, though it could be outweighed by concern for cost. We also show that certain segments of the population, particularly those who are more educated, may be open to a more extensive deployment of vertical axis turbines in urban communities."

3. Getting the numbers right: revisiting woodfuel sustainability in the developing world

"The existing projects expect to produce offsets equivalent to ~138 MtCO2e. However, when we apply NRB values derived from spatially explicit woodfuel demand and supply imbalances in the region of each offset project, we find that emission reductions are between 57 and 81 MtCO2e: 41%–59% lower than expected."

13. Attributing changing rates of temperature record-breaking to anthropogenic influences

"The frequency of hot and cold record-breaking temperature occurrences is shown to be changing due to the anthropogenic influence on the climate. Using ensembles of model simulations with and without human-induced forcings, it is demonstrated that the effect of climate change on global record-breaking temperatures can be detected as far back as the 1930s. On local scales, a climate change signal is detected more recently at most locations. The anthropogenic influence on the increased occurrence of hot record-breaking temperatures is clearer than it is for the decreased occurrence of cold records."

14. Thirty-Three Years of Marine Benthic Warming Along the US Northeast Continental Shelf and Slope: Patterns, Drivers, and Ecological Consequences

"Benthic temperatures increased throughout the domain, including in the Gulf of Maine. Rates of benthic warming ranged from 0.1 to 0.4 °C per decade, with fastest rates occurring in shallow, nearshore regions and on Georges Bank, the latter exceeding rates observed in the surface. Rates of benthic warming were up to 1.6 times faster in winter than the rest of the year in many regions, with important implications for disease occurrence and energetics of overwintering species."

Climate change impacts

39. The Future of Giant Clam-Dominated Lagoon Ecosystems Facing Climate Change

"The various documented cases support the hypothesis that mass mortalities of giant clams are triggered by climate variability, enhanced by the geomorphological specificities of these atolls. The exact mechanisms leading to mortalities and consequences for the whole ecosystem remain unknown and are probably case-dependent. These collapsing ecosystems represent well the fast impact that climate change can have on reef ecosystems."

40. Implications of Future Northwest Atlantic Bottom Temperatures on the American Lobster (Homarus Americanus) Fishery

"H. americanus experiences thermal stress at temperatures above 20°C, and projected increases in temperature is likely to result in changes in the distribution of optimal thermal egg hatching and settlement indicators. Inshore regions of southern New England, where H. americanus biomass and catch have been declining historically, will likely become inhospitable under either future scenario, while thermal egg hatching and settlement indicators will expand offshore and in the Gulf of Maine. These changes imply that members of the fishery based in southern New England may need to recapitalize to larger vessels to prepare for potential changes brought on by future climate warming."

41. Temporal changes in bird functional diversity across the United States

"We found increases in local bird species richness and taxonomic equitability that plateaued in the early 2000’s while total abundance declined over the whole period. Functional richness, the total range of traits in an assemblage, increased due to the rising prevalence of species with atypical life-history strategies and under-represented habitat or trophic preferences. However, these species did not trigger major changes in the functional composition of bird assemblages. Inter-annual variations in climate and primary productivity explained the richness of bird life-history traits in local assemblages, suggesting that these traits are influenced by broad-scale environmental factors, while others respond more to more local drivers."

69. Quantifying the influence of the terrestrial biosphere on glacial–interglacial climate dynamics

"On average across the period, the terrestrial biosphere has a −0.26?°C effect on temperature, with −0.58?°C at the Last Glacial Maximum. Depending on assumptions made about the destination of terrestrial carbon under ice sheets and where sea level has changed, the average terrestrial biosphere contribution over the last 120?kyr could be as much as −50?°C and −0.83?°C at the Last Glacial Maximum."
