Top-down and bottom-up modelling techniques have been used to answer the question of how much would it cost to reduce greenhouse gas emissions. These two types of models, however, were conceived and designed through different disciplines, for different purposes and lead to very different conclusions. Recent attempts to compare the two modelling approaches illustrate the difficulty in reconciling their results. In this paper, both modelling techniques are described and discussed, and the gap between their results is explored.
This paper presents information relevant to rule-making for geopressuredgeothermal development on state-owned lands. The analysis is focused on those potential social and economic effects of resource development, if any, which may require special attention during the leasing and permitting process. For the most part, many of the expected socioeconomic impacts are not unique to geothermal development, but are already being felt by residents of the fairways because of ongoing developmental activities. The social and economic impacts likely to result from resource development depend upon characteristics specific to the site and surrounding social and economic systems. Specific impacts and their probability, magnitude,...

Mountain streams provide important habitats for many species, but their faunas are especially vulnerable to climate change because of ectothermic physiologies and movements that are constrained to linear networks that are easily fragmented. Effectively conserving biodiversity in these systems requires accurate downscaling of climatic trends to local habitat conditions, but downscaling is difficult in complex terrains given diverse microclimates and mediation of stream heat budgets by local conditions. We compiled a stream temperature database (n = 780) for a 2500-km river network in central Idaho to assess possible trends in summer temperatures and thermal habitat for two native salmonid species from 1993 to 2006....
