Megadrought and Megadeath in 16th Century Mexico
The native population collapse in 16th century Mexico was a demographic catastrophe with one of the highest death rates in history. Recently developed tree-ring evidence has allowed the levels of precipitation to be reconstructed for north central Mexico, adding to the growing body of epidemiologic evidence and indicating that the 1545 and 1576 epidemics of cocoliztli (Nahuatl for "pest") were indigenous hemorrhagic fevers transmitted by rodent hosts and aggravated by extreme drought conditions.

Assessing the Costs of Climate Change and Adaptation in South Asia
.This Asian Development Bank (ADB) study examined the economic costs associated with the impacts of climate change and the cost and benefits of adaptation in Bangladesh,Bhutan, India, the Maldives, Nepal, and Sri Lanka. The study aimed to (i) assess the biophysical impacts of climate change in the region, including individual country impacts, and (ii) estimate the total economic loss to the countries in the region by 2100, taking into account the different scenarios and impacts projected across vulnerable sectors, and then to estimate the magnitude of funding for adaptation measures required to avert such potential losses. Results of the study will aid development of future policies and programs for climate change adaptation in the region, including initiatives for regional cooperation and capacity building in climate change management. The study covered the following sectors: agriculture, terrestrial ecosystems, water, marine and coastal resources (except Bhutan and Nepal), health, and energy.

Climate Change and Insurance: An Agenda for Action in the United States
This report is the first report of its kind that attempts to overlay a detailed distillation of climate change science with U.S. insurance industry activities around climate change. This report aims to go beyond an investigation of only hurricanes to also address the implications for the U.S. insurance industry of other impacts of climate change including forest fires, floods, and storm surge (although storm surge is not commercially insured, this report describes how government insurance backstops interact intimately with commercial insurance products and with consumer perception of risk). The report finds that U.S. insurers are far ahead of many of their overseas counterparts in assessing current catastrophic (cat) risk through sophisticated cat risk modeling that is based on historical weather events; however, U.S. insurers appear to lag behind their European peers who have begun to conduct studies of climate change and are beginning, though slowly, to incorporate future climate change scenarios into cat risk models, particularly for flooding.

Climate Change and Water: Technical Paper VI
The Technical Paper addresses the issue of freshwater. Sea level rise is dealt with only insofar as it can lead to impacts on freshwater in coastal areas and beyond. Climate, freshwater, biophysical and socio-economic systems are interconnected in complex ways. Hence, a change in any one of these can induce a change in any other. Freshwater-related issues are critical in determining key regional and sectoral vulnerabilities. Therefore, the relationship between climate change and freshwater resources is of primary concern to human society and also has implications for all living species.

Services and Supply Chains - The Role of the Domestic Private Sector in Water Service Delivery in Tanzania.
This report presents findings from a review of the service activities of informal private water vendors in Dar es Salaam. Tanzania’s capital is a rapidly growing city, and around 70% of the population lacks proper housing and lives in informal settlements. Large parts of the city remain unserved by the water utility and many of those who have access to the piped network suffer from intermittent supply. As a result, small-scale private water vendors provide an essential service for many, in particular low-income households in the city.
Predicting Global Change Impacts on Mountain Hydrology and Ecology: Integrated Catchment Hydrology/Altitudinal Gradient Studies: A workshop report
Documentation resulting from an international workshop in Kathmandu, Nepal, 30 March - 2 April 1996. The following themes were addressed by the working groups: 1. "Role of ecology and hydrology for the sustainable development in mountain regions" (the "human dimensions"). 2. "Coupled ecological and hydrological studies along altitudinal gradients in mountain regions", with a sub-group dealing with the "Assessment of the spatial distribution pattern of basic water balance components." 3. "Impacts of global change on the ecology and hydrology in mountain regions", with a sub-group on the "Identification of global change impacts on hydrology and ecology in high mountain areas."
Global Change and Mountain Regions: The Mountain Research Initiative
The strong altitudinal gradients in mountain regions provide unique and sometimes the best opportunities to detect and analyse global change processes and phenomena. Meteorological, hydrological, cryospheric and ecological conditions change strongly over relatively short distances; thus biodiversity tends to be high, and characteristic sequences of ecosystems and cryospheric systems are found along mountain slopes. The boundaries between these systems experience shifts due to environmental change and thus may be used as indicators of such changes. The higher parts of many mountain ranges are not affected by direct human activities. These areas include many national parks and other protected environments. They may serve as locations where the environmental impacts of climate change alone, including changes in atmospheric chemistry, can be studied directly. Mountain regions are distributed all over the globe, from the Equator almost to the poles and from oceanic to highly continental climates. This global distribution allows us to perform comparative regional studies and to analyse the regional differentiation of environmental change processes as characterised above. Therefore, within the IGBP an Initiative for Collaborative Research on Global Change and Mountain Regions was developed, which strives to achieve an integrated approach for observing, modelling and investigating global change phenomena and processes in mountain regions, including their impacts on ecosystems and socio-economic systems.

Decision-Support Experiments and Evaluations using Seasonal-to-Interannual Forecasts and Observational Data: A Focus on Water Resources
This Synthesis and Assessment Product focuses on the connection between the scientific ability to predict climate on seasonal scales and the opportunity to incorporate such understanding into water resource management decisions. It directly addresses decision support experiments and evaluations that have used seasonal-to-interannual forecasts and observational data, and is expected to inform (1) decision makers about the relative success of experiences of others who have experimented with these forecasts and data in resource management; (2) climatologists, hydrologists, and social scientists on how to advance the delivery of decision-support resources that use the most recent forecast products, methodologies, and tools; and (3) science and resource managers as they plan for future investments in research related to forecasts and their role in decision support. It is important to note, however, that while the focus of this Product is on the water resources management sector, the findings within this Synthesis and Assessment Product may be directly transferred to other sectors.
Florida's Global Warming Solutions: A Study for: World Wildlife Fund
This report assesses how the set of national actions presented in America’s Global Warming Solutions would affect Florida’s energy systems, carbon emissions and economy. This study finds that by 2010, the set of national actions to reduce global warming would decrease Florida’s primary energy use by 26 percent and its carbon emissions by 36 percent. They would also provide increasing annual savings reaching about $300 per-capita in 2010 and averaging about $110 per-capita per year between now and 2010. Thus, the State would cumulatively save about $17 billion over that period. The set of national actions would also create approximately 39,000 net additional jobs in Florida by 2010. They would reduce emissions of other pollutants and begin to shift the basis of the State’s economy towards more advanced, energy-efficient technologies and cleaner resources. The table below summarizes these results.
Texas' Global Warming Solutions: A Study for World Wildlife Fund
This report outlined and evaluated a plan through which the United States could reduce its annual carbon-dioxide emissions by about 654 million metric tons of carbon (MtC) by 2010, 36 percent below businesses-usual projections for that year. This brings 2010 emissions to 14 percent below 1990 emissions, thereby exceeding the reductions required under the Kyoto Protocol of the United Nations Framework Convention on Climate Change (UNFCCC). The study also found that these reductions could be obtained with net economic savings, almost 900,000 net additional jobs, and significant decreases in pollutant emissions that damage the environment, and are harmful to human health, especially of children and elderly.
New England's Global Warming Solutions: A Study for World Wild life Fund
This report presents a detailed analysis of the energy impacts, carbon and pollutant emissions reductions, and economic benefits in New England of the national policies and measures analyzed in America’s Global Warming Solutions. That study indicated that the region would reap about one sixth of the net national employment created. As two years have passed since that study was begun, time has been lost for pursuing and implementing the policies and measures evaluated along the same temporal path. Now, achieving such benefits by 2010 would require an even more aggressive set and schedule of policies, or else the benefits would occur somewhat later in time. Nonetheless, these results show that a truly aggressive national policy commitment to the problem of climate change could achieve large near-term carbon emissions reductions along with environmental and economic gains.
Turning Up the Heat: How Global Warming Threatens Life in the Sea
This new report argues that rising temperatures have impacted the world's oceans to a far greater extent than previously acknowledged. Addressing topics such as sea-level rise, ocean circulation, coral reefs, sea birds and invertebrates, as well as the increasing threats to Salmon, the report predicts a dangerous chain reaction in marine ecosystems if global warming continues unabated. On the positive side, it also argues that decisive actions now to reduce pollution can slow the warming and preserve the world's oceans.

China in the International Politics of Climate Change: A Foreign Policy Analysis
This report looks into the developments in China’s political response to the threat of climate change from the late 1980s when the problem emerged on the international political agenda, until 2004. Three theoretically based explanatory models are employed to identify the factors that have influenced Chinese foreign policy-making on climate change in the past, and furthermore how these factors are likely to influence China’s future climate change policy. The three models emphasize respectively: national interests in terms of costs and benefits; domestic political bargaining; and learning through diffusion of knowledge and norms.

Antarctic fact-file
Antarctica is a continent for science. All countries working in Antarctica carry out scientific research, in a surprising range of physical and biological sciences, from the vastness of space to the minute scale of micro-organisms. Activities are regulated by the Antarctic Treaty, which has been in force since 1959 and is signed by all countries operating there. The Treaty reserves the continent for peaceful purposes, and all military and industrial activities are banned.
Climate change
The Earth's climate has not been constant over geological time. This record is contained in ice, which has built up as snowfall accumulated in distinct yearly layers. Pockets of air trapped between the snow crystals contain traces of past atmospheres, which in turn tell us about the climate at the time the snow formed. Glaciologists collect this record by drilling ice cores and then use sensitive chemical techniques to analyse the layers.
The ozone hole
Discovery of the hole in the ozone layer showed that human activity can have major, and often unexpected impacts on the planet. The destruction of ozone in the stratosphere high above the planet's surface has been brought about as the result of the widespread use of chemicals which under normal conditions are chemically inert and harmless
Understanding ecosystems
Plants and animals live in environments which change over different periods of time. Some changes happen each year with the seasons, whilst others take hundreds or even millions of years. As these changes occur, living organisms respond in different ways. To cope with the changing seasons, individuals can change their physiology or behaviour, for instance by hibernating or migration. In response to longer-scale change, species may adapt through evolutionary change. If they cannot, they must either move away or become extinct.
The Surface Ocean - Lower Atmosphere Study: Science Plan and Implementation Strategy
SOLAS (Surface Ocean - Lower Atmosphere Study) is a new international research initiative that has as its goal: To achieve quantitative understanding of the key biogeochemical-physical interactions and feedbacks between the ocean and the atmosphere, and of how this coupled system affects and is affected by climate and environmental change. Achievement of this goal is important in order to understand and quantify the role that ocean-atmosphere interactions play in the regulation of climate and global change. The domain of SOLAS is focussed on processes at the air-sea interface and includes a natural emphasis on the atmospheric and upper-ocean boundary layers, while recognising that some of the processes to be studied will, of necessity, be linked to significantly greater height and depth scales. SOLAS research will cover all ocean areas including coastal seas and ice covered areas. A fundamental characteristic of SOLAS is that the research is not only interdisciplinary (involving biogeochemistry, physics, mathematical modelling, etc.), but also involves closely coupled studies requiring marine and atmospheric scientists to work together. Such research will require a shift in attitude within the academic and funding communities, both of which are generally organised on a medium-by-medium basis in most countries.
