The instrumental period began in the Antarctic with the International Geophysical Year, about 50 years ago. The snapshot we have of the climate during this period is tiny in the long history of the continent. Determining how the environment of the Antarctic will evolve over the next century presents challenges. Climate models are the only means we have of providing synoptic views of future environmental behaviour, albeit crudely and at coarse resolution. However, the effects of increased greenhouse gases are already evident, and the effects of their expected increase over the next century, if they continue to rise at the current rate, will be remarkable because of their speed.

The United States Clean Air Act is legislation authorizing the Environmental Protection Agency to control air pollutiants on a national level.

Climate change is already with us. Scientific evidence shows that past emissions of greenhouse gases (GHG) are already affecting the Earth’s climate.Without further policies to combat climate change, the OECD projects GHG emissions will grow by about 52% by 2050.This Policy Brief highlights the OECD’s work on the likely impact of various courses of action to mitigate climate change, and the costs of inaction.

This document, part of the Synthesis and Assessment Products described in the U.S. Climate Change Science Program (CCSP) Strategic Plan. Climate affects the design, construction, safety, operations, and maintenance of transportation infrastructure and systems. The prospect of a changing climate raises critical questions regarding how alterations in temperature, precipitation, storm events, and other aspects of the climate could affect the nation's roads, airports, rail, transit systems, pipelines, ports, and waterways. Phase I of this regional assessment of climate change and its potential impacts on transportation systems addresses these questions for the region of the U.S. central Gulf Coast between Galveston, Texas and Mobile, Alabama. This region contains multimodal transportation infrastructure that is critical to regional and national transportation services. Historical trends and future climate scenarios were used to establish a context for examining the potential effects of climate change on all major transportation modes within the region. Climate changes anticipated during the next 50 to 100 years for the central Gulf Coast include warming temperatures, changes in precipitation patterns, and increased storm intensity. The warming of the oceans and decline of polar ice sheets is expected to accelerate the rate of sea level rise globally. The effects of sea level …

Water plays a key role in the development and functioning of society by serving as a basic resource for activities such as irrigation, livestock production, fisheries, aquaculture, and hydroelectric power. Adequate water use in house-holds, businesses and manufacturing is a prerequisite of economic growth. Since many of the world's diseases are waterborne, we need clean water and sanitation for reducing the incidence of these diseases. And, most significantly, water provides habitat and sustenance for a rich diversity of plant and animal species that make up aquatic and riparian ecosystems, providing the basis for many of the goods and services received by society. Society is forcing unprecedented changes on global water resources through worldwide abstraction and pollution of water. Society also has a pervasive indirect impact because anthropogenic greenhouse gas emissions are causing long-term global changes in weather extremes and climate. Changes in the global water system are difficult to understand with simple cause-effect relationships because of the intense and complex linkages and feedbacks between different parts of the system. These changes and linkages also sometimes lead to abrupt changes in water systems such as the eutrophication of coastal aquatic systems, loss of biodiversity, the exceedance of safe water supply in …
