Global Effects Of Climate Change On Wildfire: Causal Relationships Of Fire, The Natural Environment And Human Activities, Lindon N. Pronto
Global Effects Of Climate Change On Wildfire: Causal Relationships Of Fire, The Natural Environment And Human Activities, Lindon N. Pronto
Lindon N Pronto
Climate change and human activity is significantly impacting the frequency and severity of wildfires across the globe. Although climate change and human population are the overarching factors affecting wildfires in the current dialogue, the issues are more complex and often not fully understood. These issues range from global temperature increases and severe drought cycles to the relatively new phenomenon of the wildland urban interface (WUI). This is the area where structures are integrated with or immediately surrounded by areas of moderate to high fire risk and are directly linked to fuel types and topographic features. Because climate change is such …
The Influence Of Land Use And Climate Change On Forest Biomass And Composition In Massachusetts, Usa, J. R. Thompson, D. R. Foster, R. Scheller, David B. Kittredge
The Influence Of Land Use And Climate Change On Forest Biomass And Composition In Massachusetts, Usa, J. R. Thompson, D. R. Foster, R. Scheller, David B. Kittredge
David B. Kittredge
Land use and climate change have complex and interacting effects on naturally dynamic forest landscapes. To anticipate and adapt to these changes, it is necessary to understand their individual and aggregate impacts on forest growth and composition. We conducted a simulation experiment to evaluate regional forest change in Massachusetts, USA over the next 50 years (2010–2060). Our objective was to estimate, assuming a linear continuation of recent trends, the relative and interactive influence of continued growth and succession, climate change, forest conversion to developed uses, and timber harvest on live aboveground biomass (AGB) and tree species composition. We examined 20 …

Federal Energy Efficiency And Conservation Laws, John Dernbach, Marianne Tyrrell
John C. Dernbach
This paper provides an overview of U.S. law and policy concerning energy efficiency and conservation. The United States appears torn between two narratives - one expressing the abundant demonstrated opportunities provided by energy savings and the other based on a fear of deprivation from using less energy. Rather than choosing between the two, U.S. law and policy splits the difference - embracing efficiency and conservation more or less halfheartedly. Energy efficiency and conservation policy thus has a Groundhog Day aspect, in which the same or similar arguments are made year after year, decade after decade, and often (it appears) to …
Impacts Of Tropospheric Ozone And Climate Change On Net Primary Productivity And Net Carbon Exchange Of China's Forest Ecosystems, Wei Ren, Hanqin Tian, Bo Tao, Arthur Chappelka, Ge Sun, Chaoqun (Crystal) Lu, Mingliang Liu, Guangsheng Chen, Xiaofeng Xu

We investigated how ozone pollution and climate change/variability have interactively affected net primary productivity (NPP) and net carbon exchange (NCE) across China's forest ecosystem in the past half century. Using the dynamic land ecosystem model (DLEM) in conjunction with 10-km-resolution gridded historical data sets (tropospheric O3 concentrations, climate variability/change, and other environmental factors such as land-cover/land-use change (LCLUC), increasing CO2 and nitrogen deposition), we conducted nine simulation experiments to: (1) investigate the temporo-spatial patterns of NPP and NCE in China's forest ecosystems from 1961–2005; and (2) quantify the effects of tropospheric O3 pollution alone or in combination with climate variability …

Much concern has been raised regarding how and to what extent climate change and intensive human activities have altered water use efficiency (WUE, amount of carbon uptake per unit of water use) in monsoon Asia. By using a process-based ecosystem model [dynamic land ecosystem model (DLEM)], we examined effects of climate change, land use/cover change, and land management practices (i.e. irrigation and nitrogen fertilization) on WUE in terrestrial ecosystems of monsoon Asia during 1948–2000. Our simulations indicated that due to climate variability/change, WUE in the entire area decreased by 3·6% during the study period, with the largest decrease of 6·8% …
The Essential And Growing Role Of Legal Education In Achieving Sustainability, John Dernbach
The Essential And Growing Role Of Legal Education In Achieving Sustainability, John Dernbach
John C. Dernbach
This article suggests that law schools need to play a leading role in the national and global effort to achieve sustainability, including the effort to address climate change. The article first describes the various drivers for sustainability in law schools. Clients are increasingly demanding that their lawyers 'walk the talk,' as many businesses and corporations already are. The universities that provide an institutional home for most law schools are also adopting sustainability policies and practices that influence their law schools. Within the legal profession, the American Bar Association, as well as many state and local bar associations, have adopted a …
Where Do We Stand On Global Warming?, Raymond S. Bradley
Where Do We Stand On Global Warming?, Raymond S. Bradley
Raymond S Bradley
Global temperatures have risen by ~0.8°C since the end of the 19th century. This increase has not been linear, as there have been periods when temperatures were stable for short periods before rising once again. The reasons for these changes in the rate of temperature rise are related to anthropogenic factors (sulphate aerosol pollution versus greenhouse gas inputs to the atmosphere) as well as to natural factors (volcanic eruptions, solar irradiance variations, El Ni.o/Southern Oscillation [ENSO] fluctuations, etc). Over the last decade or so, temperatures have not risen at the same rate as in previous decades, and this has led …

Natural Archives, Changing Climates, Raymond S. Bradley
Raymond S Bradley
Climatic changes have occurred throughout human history, but instrumental measurements do not provide us with a very long perspective on climate variations. In many regions, instrumental records only extend back a century or two. To understand the longer-term variability of the climate system, we rely on natural archives— sediments, ice caps, peat bogs, cave deposits, banded corals and tree rings—in which a record of past changes in climate has been preserved. They are a treasure trove of the climatic and environmental history of the planet and provide information about factors that may have caused the climate to change, such as …

The "Cash For Clunkers" Program: A Sustainability Evaluation, Marianne Tyrrell, John Dernbach
The "Cash For Clunkers" Program: A Sustainability Evaluation, Marianne Tyrrell, John Dernbach
John C. Dernbach
This article describes and evaluates the effectiveness of the Consumer Assistance to Recycle and Save Act of 2009, also known as the “Cash for Clunkers” legislation. Under this law, Congress authorized persons trading in older and less fuel-efficient motor vehicles for newer and more fuel-efficient vehicles to receive a voucher worth up to $4,500 toward the purchase of the new vehicle. The article reviews various studies assessing the effectiveness of this legislation based on economic, social, and environmental criteria. Because these criteria are consistent with the goals of sustainable development, the legislation provides important lessons for future efforts to achieve …

Energy Efficiency And Conservation: New Legal Tools And Opportunities, John Dernbach, Robert Mckinstry, Darin Lowder
John C. Dernbach
Many new and ambitious energy efficiency and conservation laws are being enacted at all levels of government—and with greater financial incentives than provided previously. These innovations are intended to overcome or minimize market barriers such as principal-agent problems, information and transaction costs, high internal discount rates, and up-front capital needs that discourage cost-saving investments. Innovations such as public-private partnerships also require significant legal input and creativity for the client to reap the often remarkably large energy and cost savings. This article reviews a range of these tools, especially financial legal mechanisms, that could help significantly reduce U.S. energy consumption.
