on marine life at the global coastal scale requires characterizing the dynamics of hypoxi for which there is currently insufficient data. A variety of baselines are used in this report. For global mean temperature, the baseline is , which is the baseline used in the IPCC Special Report on Global Warming of . as an approximation of pre-industrial temperatures. For greenhouse gases, pre-industrial concentrations estimated from ice cores for the year are used as baselines. Stabilizing global mean temperature at . to above pre-industrial levels by the The philadelphia flyers hockey team all over print hawaiian shirt end of this century will require an ambitious reduction of greenhouse gas emissions, which must begin to occur during this decade. Ye, Ruquiu , ‘An assessment of the impact of climate change caused by human activities on China’s enviromnent’.

Brown, H.M. , ‘Planning for climate change in the Arctic – the impact on energy resource development’. Climate Institute Symposium on the Arctic and Global Change, Ottaw Ontario, Canad October . This summarises the likely effects on human health following both global warming and UV-B radiation increase. ‘Environmental refugees,’ people displaced by degradation of land, flooding or drought, are becoming a much larger factor in many developing countries Jacobsen, Tickell, Debrah. Even a modest rise in global sea-levels could produce tens of millions of such refugees. Population movements from blighted agricultural regions could result in areas where crop productivity may be cut by prolonged drought or temperature stress on vulnerable crops.
potential abandonment or relocation of industrial sites as a result of climate change. Changes in availability of natural resources, particularly water, may affect the viability of industrial facilities that are dependent on such resources. There are relatively few studies on the likely impact of climate change on communities, other than some studies of likely implications of sea-level rise. Together with the anticipated disruption in atmospheric circulation and storm patterns, humanity is expected to face a significant rise in global mean sea-level. Global warming will cause a thermal expansion of the upper layers of the ocean and this expansion, together with the expected melting and movement into the ocean of some land-based glaciers, is expected to accelerate the current sea-level rise trend. A rise of – cm is expected over the next years, or cm by Working Group I Report – Summary. A rise of only cm or more in relative sea-level would displace many residents of the delta regions of the Nile, the Ganges and the Yangtze from their homes and livelihoods and could render uninhabi island nations such as the Maldives in the Indian Ocean, and Kiribati, Tuvalu and the Marshall Islands in the Pacific . This projected sea-level rise will cause widespread coastal erosion, especially on gradually sloping coasts such as those in the Atlantic or Gulf Coasts of the US , or the West Coast of Africa . Data on crop yield changes expected for different scenarios of climate change had to be compiled for all crop commodities and geographical groupings represented in the world food model, the Basic Linked System . The temperature changes of these GCM scenarios are at or near the upper end of the range .-. projected for doubled CO warming by the scenarios, however, are near the mean temperature change . of recent doubled CO experiments documented for atmospheric GCMs with a seasonal cycle and a mixed-layer ocean . This article’s foundation is a bottom-up, sector-by-sector assessment of greenhouse-gas emissions and abatement potential. Starting with the status quo for each source of emissions , we reviewed with McKinsey colleagues and select external experts the technically feasible emission-reduction levers over different time horizons. It was immediately clear that a .-degree pathway would be unreachable if all investments modeled must deliver positive economic returns and many likely won’t, given that the externalities of emissions and related climate effects are not fully priced in. We therefore relaxed this assumption, which implies the need for regulatory incentives to account for challenging abatement opportunities. Global mean sea
