Abstract Climate change is expected to accelerate the hydrologic cycle, increase fraction of precipitation that rain, and enhance snowpack melting. The enhanced hydrological cycle also snowfall amounts due increased moisture availability. These processes are examined in this paper Colorado Headwaters region through use a coupled high-resolution climate–runoff model. Four simulations annual over conducted. verified using Snowpack Telemetry (SNOTEL) data. Results then presented regarding grid...
In this paper we examine current policies to combat drought in urban areas the United States illuminate lessons learned for building climate adaptive capacity. We conducted interviews with practitioners involved management at water utilities across U.S. understand: 1) both short- and long-term actions taken response drought; 2) perceptions of what constitutes an 'effective' whether how was measured; 3) limitations response. apply criteria from a theoretical framing capacity then 'reason by...

Climate regime shifts occur at irregular intervals and have profound persistent impacts on ocean temperature circulation patterns the dynamics of marine fish populations. Despite a growing scientific literature some attention to implications such for domestic fisheries, issue has received little in context international fishery management. This paper presents evidence significance climatic shifts, draws upon recent history conflict between Canada United States over Pacific salmon management...
This project examines the sensitivity of behavior and attitudes regarding wildfire risk to perceptions drought climate change impacts, documents current state homeowner mitigation effort in Clear Creek County, Colorado. Survey results demonstrate that homeowners have a fairly accurate understanding impact other environmental factors, majority undertaken most obvious investments, such as pruning vegetation around home. Perception weather factors has significant on perception concern about but...
Marine biological resources are likely to come under increasing stress over the course of 21st century as global climate change and ocean acidification interact with other stresses, including heavy fishing pressures marine pollution, create far reaching difficult‐to‐predict changes in species abundance, spatial distribution, trophic interactions. The governance systems place for fisheries environment, more broadly, will be critical determining extent which these can managed sustainability....
Abstract Scenarios of global climate change were examined to see what impacts they might have on transboundary water management in the Columbia River basin. Scenario changes natural streamflow estimated using a basin hydrology model. These scenarios tended show earlier seasonal peaks, with possible reductions total annual flow and lower minimum flows. Impacts adaptation responses determined through two exercises: (a) estimations system reliability reservoir model performance measures (b)...
A multi-step decision support process was developed and applied to the physically legally complex case of water diversions from Upper Colorado River across Continental Divide serve cities farms along Colorado's Front Range. We illustrate our approach by simulating performance an existing drought-response measure, Shoshone Call Relaxation Agreement (SCRA) [the adaptation measure], using Water Evaluation Planning (WEAP) tool hydrologic cycle systems model]; Statistical DownScaling Model...
Severe freezes are a serious problem for the citrus growers of central Florida. To investigate possible climatic causes intermittent freezes, this paper examines influence several atmospheric circulation patterns on winter temperatures in The Pacific/North American pattern is shown to be particularly influential and North Atlantic Oscillation also significant, while Southern does not show direct effect. A decreasing trend Florida since 1947 can explained by fluctuations former two patterns....
Using multivariate time series models, Alaska's statewide commercial catch of three salmon species during 1925-1994 is shown to be related surface temperatures in particular large regions the eastern North Pacific. Previous research has indicated that interdecadal changes Alaskan levels are large-scale climate regime The present work focuses on interannual variability by controlling for climatic shifts mid-1940s and mid-1970s. For sockeye (Oncorhynchus nerka) chum (O. keta), relationships...
ABSTRACT: This paper reports on the current assessment of climate impacts water resources, including aquatic ecosystems, agricultural demands, and management, in U.S. Great Plains. Climate change region may have profound effects users, urban industrial users alike. In central Plains Region, potential changes include winter snowfall snow‐melt, growing season rainfall amounts intensities, minimum temperature, summer time average temperature. Specifically, results from general circulation...

In the 1980s Florida was struck by an unusual series of severe freezes that caused enormous damage to citrus groves. While acreage in relatively freeze-free parts state has expanded rapidly since these freezes, serious questions remain about commercial viability growing crops some central counties. This paper considers role freeze risk plays investment decisions growers. A simplified example is used estimate tolerable levels for individuals evaluating at different discount rates, and show...
