Abstract
Lack of local information on climate change impacts is increasingly recognized as an important barrier to progress in adaptation. However, simply providing decision makers with higher-resolution climate information will not ensure successful adaptation. In order for there to be appropriate information uptake and use, it is essential to understand the political constraints and conditions under which decision makers operate. A detailed examination of the current regulatory context in relation to climate and weather impacts can provide insight into the barriers and obstacles affecting decision makers in adaptation endeavors.
This study examines the experiences of the municipalities of Tompkins County, New York, as they attempt to manage stormwater in compliance with federally mandated regulations. The current policies fail to adequately address the fundamental problems affecting local government in New York: fragmented jurisdiction, interagency communication, inability to cope with unfunded mandates, enforcement, and the promotion of informed decision making. The way forward may be the adaptive governance approach for the management of complex environmental issues. This article is intended to serve as an initial model for other university-based researchers that are interested in serving their local communities with weather, climate, and policy research and are willing to engage in the complexities involved.

Abstract
This paper describes work to improve the understanding of the broad range of factors affecting the occurrence of postfire flooding, with emphasis on an event that occurred in the Alpine Shire, Victoria, Australia, in 2003. Analysis and mesoscale modeling of the conditions surrounding the event suggests that the drivers of the extreme rainfall event were above-average precipitable water in the atmosphere, significant values of CAPE, producing strong updrafts within the thunderstorm capable of supporting large quantities of suspended water droplets, and thunderstorm cell regeneration in the same area. However, atmospheric instability was further enhanced by anabatic breezes, above-average boundary layer moisture, and increased surface heating resulting from reduced surface albedo and soil moisture of the recently burned fire surface. Flash flooding resulted, due to 1) the storm cells likely being pulse wet microbursts, 2) cell regeneration over the same area (very little horizontal movement), and 3) the small catchment size. It is likely that a further contributor to the observed flash flood was the reduced infiltration often observed in recently burned catchments; these factors will be explored in a subsequent hydrologic study. It is intended that the mechanisms elucidated in this study will assist in emergency preparedness in the Alpine Shire. Given the warmer conditions expected with near-term anthropogenic climate change for the Alpine Shire, and the concomitant increase in fires, this causal relationship, even for a relatively rare event, has implications for emergency managers and Alpine Shire residents.

Efforts are being made to develop new paradigms for climate change adaptation policy at both the national and the international levels. However, progress in vulnerability and adaptation research has not been matched by advancement on practical policy initiatives. The complexity of the challenge to develop methods and means to support adaptation to climate change necessitates a diversity of approaches. This diversity is healthy, and yet it is possible to define some key characteristics and tools that can promote practical outcomes. In this paper, some methodologies that have proved successful are reviewed. These include a mapping of contextual circumstances, an appreciation for multiple perspectives, and the importance of a “boundary object” in forging strong interactions among project participants. Further, a toolkit of approaches for natural scientists is presented. This toolkit can be used to organize work in collaboration with stakeholders and other participants and can help overcome barriers to a meaningful contribution to the policy process. Fundamentally, this challenge will require approaches that are more grounded in meaning, narration, and reflection.
