Exploring the science–policy interface on climate change: The role of the IPCC in informing local decision-making in the UK
Building on the Intergovernmental Panel on Climate Change’s (IPCC) review of
how to make its Assessment Reports (ARs) more accessible in the future, the research
reported here assesses the extent to which the ARs are a useful tool through which scientific
advice informs local decision-making on climate change in the United Kingdom. Results from
interviews with local policy representatives and three workshops with UK academics, practitioners
and local decision makers are presented. Drawing on these data, we outline three
key recommendations made by participants on how the IPCC ARs can be better utilized as a
form of scientific advice to inform local decision-making on climate change. First, to provide
more succinct summaries of the reports paying close attention to the language, content,
clarity, context and length of these summaries; second, to better target and frame the reports
from a local perspective to maximize engagement with local stakeholders; and third, to work
with local decision makers to better understand how scientific advice on climate change is
being incorporated in local decision-making. By adopting these, the IPCC would facilitate local
decision-making on climate change and provide a systematic review of how its reports are
being used locally. We discuss implications of these recommendations and their relevance to
the wider debate within and outside the IPCC as to the most effective way the IPCC can more
effectively tailor its products to user needs without endangering the robustness of its scientific
findings. This article is published as part of a collection on scientific advice to government
Knowledge and perceptions about the health impact of climate change among health sciences students in Ethiopia: a cross-sectional study
Climate Change and Local Public Health in the United States: Preparedness, Programs and Perceptions of Local Public Health Department Directors
While climate change is inherently a global problem, its public health impacts will be experienced most acutely at the local and regional level, with some jurisdictions likely to be more burdened than others. The public health infrastructure in the U.S. is organized largely as an interlocking set of public agencies at the federal, state and local level, with lead responsibility for each city or county often residing at the local level. To understand how directors of local public health departments view and are responding to climate change as a public health issue, we conducted a telephone survey with 133 randomly selected local health department directors, representing a 61% response rate. A majority of respondents perceived climate change to be a problem in their jurisdiction, a problem they viewed as likely to become more common or severe over the next 20 years. Only a small minority of respondents, however, had yet made climate change adaptation or prevention a top priority for their health department. This discrepancy between problem recognition and programmatic responses may be due, in part, to several factors: most respondents felt personnel in their health department–and other key stakeholders in their community–had a lack of knowledge about climate change; relatively few respondents felt their own health department, their state health department, or the Centers for Disease Control and Prevention had the necessary expertise to help them create an effective mitigation or adaptation plan for their jurisdiction; and most respondents felt that their health department needed additional funding, staff and staff training to respond effectively to climate change. These data make clear that climate change adaptation and prevention are not currently major activities at most health departments, and that most, if not all, local health departments will require assistance in making this transition. We conclude by making the case that, through their words and actions, local health departments and their staff can and should play a role in alerting members of their community about the prospect of public health impacts from climate change in their jurisdiction

Methane fueled engine performance and emissions characteristics
A 1983 Ford 3.8 liter V-6 engine was fueled with methane and tested on an engine dynamometer in order to begin to generate a data base that could be used to estimate emission levels and fuel economy for a driving cycle from a 3-point mini map method. The results showed that, with the proper control of pertinent engine variables, the engine would probably meet the current State of California Emission Standards that have been formulated to account for methane as an unburned hydrocarbon, without having to resort to a catalytic converter, and with Joules fuel consumption comparable, if not better than that for a gasoline-fueled vehicle. Unburned fuel in the exhaust was found to be comprised of between 87 and 96 percent methane. MBTH total aldehyde emissions were found to vary between 27 and 67 molar ppm
Effects of experimental watering but not warming on herbivory vary across a gradient of precipitation
Climate change can affect biotic interactions, and the impacts of climate on biotic interactions may vary across climate gradients. Climate affects biotic interactions through multiple drivers, although few studies have investigated multiple climate drivers in experiments. We examined the effects of experimental watering, warming, and predator access on leaf water content and herbivory rates of woolly bear caterpillars (Arctia virginalis) on a native perennial plant, pacific silverweed (Argentina anserina ssp. pacifica), at two sites across a gradient of precipitation in coastal California. Based on theory, we predicted that watering should increase herbivory at the drier end of the gradient, predation should decrease herbivory, and watering and warming should have positive interacting effects on herbivory. Consistent with our predictions, we found that watering only increased herbivory under drier conditions. However, watering increased leaf water content at both wetter and drier sites. Warming increased herbivory irrespective of local climate and did not interact with watering. Predation did not affect herbivory rates. Given predictions that the study locales will become warmer and drier with climate change, our results suggest that the effects of future warming and drying on herbivory may counteract each other in drier regions of the range of Argentina anserina. Our findings suggest a useful role for range-limit theory and the stress-gradient hypothesis in predicting climate change effects on herbivory across stress gradients. Specifically, if climate change decreases stress, herbivory may increase, and vice versa for increasing stress. In addition, our work supports previous suggestions that multiple climate drivers are likely to have dampening effects on biotic interactions due to effects in different directions, though this is context-dependent
