United Nations Framework Convention on Climate Change At the Climate Change Conference in Bali, Parties to the UNFCCC decided to launch formal negotiations on a strengthened international deal on climate change. Whilst welcoming the statement of the G8 on climate change and the environment made in Hokkaido, Japan, this week, UN Secretary-General BAN-Ki moon called on G8 countries to agree to ambitious mid-term emission reduction targets for developed countries by next year in Copenhagen. The United Nations Climate Change secretariat announces the launch of its fellowship programme, the objective of which is to contribute to building capacity for addressing climate change in Parties not included to Annex I to the Convention, in particular Parties that are small island developing States or least developed countries. unfccc.int   (785 words)

Climate Change - Global Climate Change Initiative - global warming - climate change - The Nature Conservancy Climate change is already affecting our lives and the places we live, and has the potential to dramatically impact the lives of future generations. Climate change is caused by the emission of heat-trapping gases – mostly carbon dioxide (CO) – from vehicles, industry, power plants and deforestation. Climate change, on the other hand, is a more general term that refers to changes in many climatic factors (such as temperature and precipitation) around the world. www.nature.org /initiatives/climatechange   (505 words)

Climate change - Encyclopedia of Earth Climate change refers to a change in the state of the climate that can be identified by changes in the average and/or the variability of its properties (e.g., temperature, precipitation), and that persists for an extended period, typically decades or longer. Climate change may be due to natural internal processes or external forcings, or to persistent anthropogenic changes in the composition of the atmosphere or in land use. Climate change is projected to bring some benefits in temperate areas, such as fewer deaths from cold exposure, and some mixed effects such as changes in range and transmission potential of malaria in Africa. www.eoearth.org /article/Climate_change   (7784 words)

Climate Change - An Australian Guide to the Science and Potential Impacts Based on the SRES scenarios used by the IPCC, and regional changes in climate simulated by nine climate models, annual average temperatures in Australia are projected to increase by 0.4 to 2.0 °C by 2030, and 1.0 to 6.0 °C by 2070, relative to 1990. Projections for changes in annual rainfall suggest changes in the south-west lie in the range of -20% to +5% by 2030, and -60% to +10% by 2070, with changes of -10% to +5% by 2030 and -35% to +10% by 2070 in parts of south-eastern Australia. Climate change, and our understanding of it, is evolving rapidly in the real world, and on the scientific, technological and policy fronts, so policies and decisions need to be decided on the basis of the best current information, but in the knowledge that they will need to be adjusted with time. www.greenhouse.gov.au /science/guide/index.html   (4351 words)

Climate Change : Level 1 - Summary on Climate Change and Global Warming Projected changes in climate are expected to have both beneficial and adverse effects on water resources, agriculture, natural ecosystems and human health. Ecosystems have a limited capacity to adapt to climate change; some might not be able to cope as they had done in earlier periods and are expected to suffer damages because: The rate and extent of climate change is expected to be faster and greater than in the past and could exceed nature's maximum adaptation speed; More... www.greenfacts.org /studies/climate_change/level_1.htm   (1355 words)

Basic Information | Climate Change | U.S. EPA The term climate change is often used interchangeably with the term global warming, but according to the National Academy of Sciences, "the phrase 'climate change' is growing in preferred use to 'global warming' because it helps convey that there are [other] changes in addition to rising temperatures." Climate change refers to any significant change in measures of climate (such as temperature, precipitation, or wind) lasting for an extended period (decades or longer). In fact, Alaska has been experiencing significant changes in climate in recent years that may be at least partly related to human caused global climate change. epa.gov /climatechange/basicinfo.html   (1357 words)

Climate change is widely considered to be one of the gravest threats to the sustainability of the planet's environment, the well-being of its people and the strength of its economies. Climate change and the G8 Climate change was made one of the two priorities, along with the development of Africa, at the G8 summit 2005 (held in Gleneagles, Scotland, July 6-8) gathering the eight leading industrialised nations: the United States, Canada, Britain, Germany, France, Italy, Japan and Russia. www.choike.org /nuevo_eng/informes/268.html   (7261 words)

Climate change: some basics Assessing the climatic effects of aerosols involves modeling of regional climates and of clouds, both of which are not yet very reliable. To further complicate matters, cloud properties may change with a changing climate, and human-made aerosols may confound the effect of greenhouse gas forcing on clouds. The risk of rapid climate change is linked to many other problems of concern, like population growth, poverty, loss of biodiversity, or stratospheric ozone depletion. www.faqs.org /faqs/sci/climate-change/basics   (7932 words)

Global Warming Frequently Asked Questions Evidence such as changes in glacial mass balance (the amount of snow and ice contained in a glacier) is useful since it not only provides qualitative support for existing meteorological data, but glaciers often exist in places too remote to support meteorological stations. Large and rapid climatic changes affecting the atmospheric and oceanic circulation and temperature, and the hydrological cycle, occurred during the last ice age and during the transition towards the present Holocene period (which began about 10,000 years ago). Climate models are constantly improving based on both our understanding and the increase in computer power, though by definition, a computer model is a simplification and simulation of reality, meaning that it is an approximation of the climate system. lwf.ncdc.noaa.gov /oa/climate/globalwarming.html   (3356 words)

Climate Change - Wikibooks, collection of open-content textbooks The term anthropogenic climate change is used to attribute changes in Earth's climate to activities of humans. Climate change has become a "hot button" issue over the past few years, and this has only become more extreme as United States policy on climate change as diverged from much of the rest of the world and the scientific community. Is it not reflecting the change in the behaviour ofhte monsoon. en.wikibooks.org /wiki/Climate_change   (5558 words)

Environment - Climate Change Climate change is already happening and represents one of the greatest environmental, social and economic threats facing the planet. The warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global mean sea level. In its Fourth Assessment Report (AR4), published in 2007, the Intergovernmental Panel on Climate Change (IPCC) projects that, without further action to reduce greenhouse gas emissions, the global average surface temperature is likely to rise by a further 1.8-4.0°C this century, and by up to 6.4°C in the worst case scenario. ec.europa.eu /environment/climat/home_en.htm   (954 words)

WHO | Climate Change and Human Health Climate change is a significant and emerging threat to public health, and changes the way we must look at protecting vulnerable populations. The most recent report of the Intergovernmental Panel on Climate Change confirmed that there is overwhelming evidence that humans are affecting the global climate, and highlighted a wide range of implications for human health. Climate change already contributes to the global burden of disease, and this contribution is expected to grow in the future. www.who.int /globalchange/climate/en   (364 words)

Climate Change In September, a group of experts from the genetic conservation, climate science, agricultural development, and plant genetics communities met at the RF Conference Center in Bellagio for a discussion addressing the management of crop genetic conservation in the face of climate change. The head of the Intergovernmental Panel on Climate Change -- which along with Al Gore was awarded the Nobel Peace Prize -- visited the Rockefeller Foundation headquarters in New York today and spoke with both the Board of Trustees and the staff about mitigation and adaptation to global climate changes. Recognizing that various levels of impact from climate change are unavoidable, and in some instances could be devastating, the Rockefeller Foundation’s $70 Million Initiative seeks to build the resilience of communities most likely to be hardest hit by climate change. www.rockfound.org /initiatives/climate/climate_change.shtml   (870 words)

Global Climate Change President Bush is addressing the complex and important issue of global climate change with an ambitious strategy: slow the rate of increase in greenhouse gas emissions, and then, as the science justifies, stop – and then reverse – the accumulation of greenhouse gas emissions in the atmosphere. Climate VISION Partnership: In February 2003, President Bush announced that companies from twelve major industrial sectors and the membership of the Business Roundtable had committed to work with four of his Cabinet agencies (DOE, EPA, DOT, and USDA) to reduce their greenhouse gas emissions in the next decade. Climate Leaders: Announced in 2002, “Climate Leaders” is an EPA partnership encouraging individual companies to develop long-term, comprehensive climate change strategies. www.whitehouse.gov /ceq/global-change.html   (1564 words)

Climate Change (Index) Despite mounting evidence of the reality of climate change, the gap between scientific understanding of the gravity of the problem on the one hand and policy action on the other remains wide. SSI members regularly communicate with legislators and key administration officials to strengthen and support sound science-based policies to reduce the threat of climate change, whether it be interacting at international climate negotiations or challenging congressional efforts to muzzle the Environmental Protection Agency's global warming educational outreach. Having heard from senior Hill staffers that ignorance and misinformation about the most basic climate science still exists among many legislators, SSI has sponsored a series of meetings between a coalition of scientists and their congressional representatives in Washington, D.C. to discuss climate change issues. www.ucsusa.org /ssi/climate_change   (510 words)

Workshop Climate Change 2007 The aims of the conference were to discuss the impacts of global climate change on the Wadden Sea and the Wadden Sea region and to elaborate possible adaptation strategies. A possible solution for estuarine restoration and adaptation to sea level rise could be a floating harbour central to several ports of the North Sea, to transfer cargo from large to small vessels or into pipeline connections to the mainland. Changes in these environmental factors will result in shifts in habitats and species, and in their interactions. www.waddensea-secretariat.org /news/symposia/climatechange/climatechange2007.html   (1665 words)
