					IPCC Special reports IPCC Special Report "Extreme Events and Disasters (SREX)" (2012) IPCC just published the Summary for Policymakers of the new special report on "Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation (SREX)". The report was three years in preparation and it synthesises thousands of recent, peer-reviewed scientific studies. It is officially released on November 18th 2011 in Kampala, Uganda. The full SREX report was published in February 2012. ...> 2011 IPCC Special Report "Renewable Energy Sources and Climate Change Mitigation" (2011) Close to 80 percent of the world‘s energy supply could be met by renewables by mid-century if backed by the right enabling public policies a new report shows. The findings, from over 120 researchers working with the Intergovernmental Panel on Climate Change (IPCC), also indicate that the rising penetration of renewable energies could lead to cumulative greenhouse gas savings equivalent to 220 to 560 Gigatonnes of carbon dioxide (GtC02eq) between 2010 and 2050. ...> Impacts of Ocean Acidification on Marine Biology and Ecosystems (2011) IPCC Expert Meeting Report, Bankoku Shinryokan Okinawa, Japan 17–19 January 2011 Understanding the effects of increasing atmospheric CO2 concentrations on ocean chemistry, commonly termed ocean acidification, as well as associated impacts on marine biology and ecosystems, is an important component of scientific knowledge about global change. The Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC) will include comprehensive coverage of ocean acidification and its impacts, including potential feedbacks to the climate system. To support ongoing AR5 assessment efforts, Working Group II and Working Group I (WGII and WGI) of the IPCC held a joint Workshop on Impacts of Ocean Acidification on Marine Biology and Ecosystems in Okinawa, Japan, from 17 to 19 January 2011. The workshop convened experts from the scientific community, including WGII and WGI AR5 authors and review editors, to synthesise scientific understanding of changes in ocean chemistry due to increased CO2 and of impacts of this changing chemistry on marine organisms, ecosystems, and ecosystem services. ...> 2010 Assessing and Combining Multi Model Climate Projections (2010) IPCC Expert Meeting Report of 25-27 January 2010 Climate model results provide the basis for projections of future climate change and increasing numbers of models are likely to contribute to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR5). The heterogeneity in the new generation of climate models and an increasing emphasis on estimates of uncertainty in the projections raise questions about how best to evaluate and combine model results in order to improve the reliability of projections. ...> Sea Level Rise and Ice Sheet Instabilities (2010) IPCC Expert Meeting Report of 21–24 June 2010 Sea level rise is one of the major long-term consequences of human-induced climate change. Future projections of sea level changes and their regional expression are of crucial importance for the sustainability of coastal settlements around the world. ...> Detection and Attribution Related to Anthropogenic Climate Change (2010) IPCC Expert Meeting Report of 14–16 September 2009 The reliable detection and attribution (D&A) of changes in climate and their effects is fundamental to understanding the scientific basis of climate change and in enabling decision makers to manage climate-related risk. ...> Climate Change and Water (2008) IPCC Technical Paper Observational records and climate projections provide abundant evidence that freshwater resources are vulnerable and have the potential to be strongly impacted by climate change, with wide-ranging consequences for human societies and ecosystems. Individual chapters of the full report ...> Towards new scenarios for the analysis of emissions, climate change, impact, and response strategies (2007) IPCC Expert Meeting Report of 19 - 21 September 2007 Scenarios of potential future anthropogenic climate change, underlying driving forces, and response options have always been an important component of the work of the Intergovernmental Panel on Climate Change (IPCC). The IPCC decided that rather than directly coordinating and approving new scenarios itself, the process of scenario development should now be coordinated by the research community. The IPCC would seek to “catalyze” the timely production by others of new scenarios for a possible Fifth Assessment Report (AR5). For this purpose it conveened an expert meeting to consider the scientific community’s plans for developing new scenarios, and to identify a set of “benchmark emissions scenarios” (now referred to in this report as “Representative Concentration Pathways-RCPs”. The RCPs will be used to initiate climate model simulations for developing climate scenarios for use in a broad range of climate-change related research and assessment and were requested to be “compatible with the full range of stabilization, mitigation and baseline emissions scenarios available in the current scientific literature.” ...> Carbon Dioxide Capture and Storage (2005) IPCC Special Report ...> Safeguarding the ozone layer and the Global Climate System (2005) IPCC Special Report The WMO/UNEP Intergovernmental Panel on Climate Change (IPCC) finalized a Special Report on «Safeguarding the ozone layer and the global climate system: issues related to hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs)«. This Special Report describes both scientific and technical information regarding alternatives to ozone-depleting substances (ODSs) that may affect the global climate system. It addresses scientific linkages between stratospheric ozone depletion and climate change, and how the phase-out of ODSs is affecting climate change. HFCs have no ozone-depleting potential but are greenhouse gases, and are used as replacements for ODSs. The report assesses options to reduce emissions of these greenhouse gases, explores their technical feasibility and cost, and addresses environmental, safety and health considerations. The full report will be published in mid-2005 by Cambridge University Press.

Biodiversity change may have many different causes such as land-use and land-cover change, soil and water pollution and degradation and air pollution, diversion of water to intensively managed ecosystems and urban systems, habitat fragmentation, selective exploitation or the introduction of non-native species, and stratospheric ozone depletion. The current rate of biodiversity loss is greater than the natural background loss of extinction. ...> IPCC Special Report on land use, land use change and forestry (2000) The special report of the Intergovernmental Panel on Climate Change (IPCC) reviews the current understanding of the relationship between land use (especially forestry), carbon dioxide emissions and the Kyoto Protocol agreements. The following topics are covered: How does the global carbon cycle operate, and how is it related to forestry activities? What are the accounting rules? How do the models and ground-based assessments of changes in carbon stocks compare? What are the short term prospects for policy implementation? What are the implications for sustainable development? The full text of the report may be downloaded as pdf file (145 kbyte) from the IPCC Server http://www.ipcc.ch/pub/SPM_SRLULUCF.pdf ...> IPCC Special Report on Aviation and the Global Atmosphere (1999) The Intergovernmental Panel on Climate Change (IPCC) has released a special report on the effect of aviation on the global atmosphere entitled «Aviation and the Global Atmosphere«. The report represents the results of unprecedented collaboration between the IPCC and the Scientific Assessment Panel of the Montreal Protocol on Substances that Deplete the Ozone Layer, and provides a detailed assessment of the impact of aircraft engine emissions on climate and atmospheric ozone. ...>
