Train versus plane in a busy world. Schedules provided for train and plane for the following routes: New York-Washington D.C., Tokyo-Osaka, Paris-London and Hamburg-Münich.

One certified emission reduction unit is equivalent to a one-tonne reduction in greenhouse gas emissions (measured in CO2 equivalent).

Household appliances with a standby mode and CO2 emissions from standby mode. Displayed in million tonnes per year for various countries all around the world.

Climate change global processes and effects involving human activities, main climate features and major threats.

You do always have the option of remembering how much energy went into building your house.

Countries that are signatories to the Kyoto Protocol have a tool for helping them in the Emissions Trading Scheme. In the Kyoto scheme each allowance is called an Assigned Amount Unit (AAU). Each entity equals one tonne of CO2 equivalent.

Buildings (residential and commercial) account for 10 to 15% of all greenhouse gas emissions, including almost 70% carbon dioxide and 25% methane.

Meat imports in 2005 and Meat consumption displayed as kilograms of CO2 equivalents per 100 kilocalories of product for major countries around the world.

Red areas where high percentage of children with stunted growth - used as a proxy for poverty - coincide with a high freshwater biodiversity index - a proxy for biodiversity - likely indicate areas in which poor people have no other choice than to unsustainably extract resources, in turn threatening biodiversity.

This map may be used to show areas in which biodiversity is threatened in relation to poverty on a continental scale. Areas where high percentage of underweight children - used as a proxy for poverty - coincide with a high occurrence of amphibian species and endemic bird areas - a proxy for biodiversity - may indicate areas in which poor people likely have no other choice than the unsustainable extraction of resources, in turn threatening biodive...

This map may be used to show areas in which biodiversity is threatened. Areas where high poverty and high population density coincides with high biodiversity may indicate areas in which poor people likely have no other choice than to unsustainably extract resources, in turn threatening biodiversity. The map has been produced from three primary data sources – stunted growth data collected on first level administrative units from FAO (FAO 2004), po...

Some of the world's least developed countries are located in hotspot areas of high importance for biodiversity. This map displays Human Development Index (UNDP) by country and hotspot regions overlaid on that.

The relative species abundance, as a ratio of the biodiversity before the advent of man, is high in desert areas. The areas are relatively pristine and has seen little changes induced by human activities. Impacts are most clearly seen at the edges of deserts, in the basins of western North America, along Baja California, and in the drylands of Central Asia and the inland Far East. The graphic is using the IPCC SRES A2 experiment as a parameter.

In desert areas by 2050, the majority of the temperature increase, according to the NCAR-CCSM3 model (and the IPCC SRES A2 scenario), will occur in the Northern Sahara, western Australia and in the inland deserts of North America. The precipitation will increase closer to the equator, but with large decreases primarily in Australia.

The main land use change in desert areas has been the conversion of relatively barren drylands for agricultural needs, partially through irrigation. The conversion has historically primarily been to use the land for grazing, but the 2050 scenario suggests that small areas on the fringes of deserts will be converted to cropland. The model otherwise predicts modest changes for 2050.

SRES scenarios show the period 2071 to 2100 relative to the period 1961 to 1990, and were performed by AOGCMs. Scenarios A2 and B2 are shown as no AOGCM runs were available for the other SRES scenarios.

The impact of human activities on wilderness qualities has been modelled using the GLOBIO-2 model. The model uses infrastructure and settlements as proxies and measure the degree by which habitats have reduced their wilderness qualities, by fragmentation and disturbance. According to the model, huge tracts of desert areas are relatively undisturbed, the majority of highly impacted areas are in the drylands of Central Asia and North America.

Species that has been introduced on purpose or spread in the wild threaten livelihoods in agriculture or water resources. As illustrated in this map, some regions of South Africa have very high ratios of invasive alien plants and are subject to government projects to limit the distribution and information campaigns informing the public.

The graph shows the total emission of 6 major greenhouse gases in Norway from 1985 to 1996 with projections to 2010. Greenhouse gases are largely produced through human activities including industrial processes, fossil fuel combustion, and changes in land use, such as deforestation.

The graph shows emissions of N2O in Norway from 1985 to 1996. Nitrous oxide (N2O) is emitted to the atmosphere by both natural such as combustion and anthropogenic sources such as industrial processes and fertilizers.
