Re-infestation by 'Aedes aegypti' Re-infestation by 'Aedes aegypti'
Climate change affect the health of the population, not only through heat waves and waterborne diseases, but also as a result of the expansion of geographical areas conducive to the transmission of vector-borne diseases such as yellow fever, dengue and malaria. Species of mosquitoes, such as the group ‘Anopheles gambiae’, ‘A. funestus’, ‘A. darlingi’, ‘Culex quinquefasciatus’ and ‘Aedes aegypti’, are responsible for propagation of the majority of...

Fifty million climate refugees by 2010 Fifty million climate refugees by 2010
Today we find a world of asymmetric development, unsustainable natural resource use, and continued rural and urban poverty. There is general agreement about the current global environmental and development crisis. It is also known that the consequences of these global changes have the most devastating impacts on the poorest, who historically have had limited entitlements and opportunities for growth.

Larimichthys polyactis Catch in early 2000s and predicted Catch Shift Larimichthys polyactis Catch in early 2000s and predicted Catch Shift
(a) Current (early 2000s) and (b) climate-shifted distributions of the small yellow croaker Larimichthys polyactis (Sciaenidae). The climate-shifted distribution was predicted by a dynamic bioclimate envelope model described by Cheung et al. (2008), under a hypothetical increase in average global ocean temperature of 2.5°C. Boundaries of Exclusive Economic Zones are delineated by the dashed lines.

Human use and conversion of tropical forests Human use and conversion of tropical forests
Tropical forests hold the largest terrestrial carbon store and are active carbon sinks. Reducing emissions from deforestation and degradation is a vital component of tackling dangerous climate change. In addition, tackling illegal and ill-managed logging will be an important part of reducing emissions from forestry.

Maps of average sea ice extent in the Arctic summer (September) and winter (March), and in the Antarctic summer (February) and winter (September) Maps of average sea ice extent in the Arctic summer (September) and winter (March), and in the Antarctic summer (February) and winter (September)
Passive microwave sensors on satellites have monitored the extent of the sea ice cover since 19782. This technique is widely used to investigate fluctuations in ice extent over the seasons, variability between years, and longterm trends. The seasonal variation of ice extent is much greater in the Antarctic where there is about six times as much ice in winter as in summer. Currently, in the Arctic, ice approximately doubles from summer to winter. ...

Uptake of Carbon Dioxide from the Atmosphere Uptake of Carbon Dioxide from the Atmosphere
Arctic marine systems currently provide a substantial carbon sink but the continuation of this service depends critically on arctic climate change impacts on ice, freshwater inputs, and ocean acidification.

World ocean thermohaline circulation (alternative version) World ocean thermohaline circulation (alternative version)
The global conveyor belt thermohaline circulation is driven primarily by the formation and sinking of deep water (from around 1500m to the Antarctic bottom water overlying the bottom of the ocean) in the Norwegian Sea. When the strength of the haline forcing increases due to excess precipitation, runoff, or ice melt the conveyor belt will weaken or even shut down. The variability in the strength of the conveyor belt will lead to climate change in...

Historical trends in carbon dioxide concentrations and temperature, on a geological and recent time scale Historical trends in carbon dioxide concentrations and temperature, on a geological and recent time scale
The most recent geological history, in the last hundred thousand years, has been characterised by cycles of glaciations, or ice ages. The historic temperatures, through these times, have been low, and continental ice sheets have covered large parts of the world. Through ancient air, trapped in tiny bubbles in the Antarctic ice, we have been able to see what the temperature cycle was at that time, and also the concentration of carbon dioxide (CO2)...

Increases in annual temperatures for a recent five-year period, relative to 1951-1980 Increases in annual temperatures for a recent five-year period, relative to 1951-1980
Warming is widespread, generally greater over land than over oceans, and the largest gains in temperatures for the planet are over the North American Arctic, north central Siberia, and on the Antarctic Peninsula. These recent increases in temperature are confirmed by changes in other features: loss of sea ice, shift of tundra to shrub vegetation, and migration of marine and terrestrial ecosystems to higher latitudes.

Greenland, showing rates of surface-elevation change between the late 1990s and 2003 Greenland, showing rates of surface-elevation change between the late 1990s and 2003
Mass-balance estimates for Greenland show thickening at high elevations since the early 1990s at rates that increased to about 4 cm per year after 2000, consistent with expectations of increasing snowfall in a warming climate. However, this mass gain is far exceeded by losses associated with large increases in thinning of the ice sheet near the coast. Total loss from the ice sheet more than doubled, from a few tens of billions of tonnes per year ...

Caspian and Balkhash endemic species are under threat of extinction. It is estimated that ten percent of total area needs to be protected in order to sustain development and the countries of the region are seriously behind that benchmark.

The graphic shows emissions of anthropogenic greenhouse gases from 1990 to 1995, with projections to 2020. The main greenhouse gases are CO2, CH4, N2O, HFCs, PFCs and SF6. GLobal warming is largely believed to be the result of emissions of greenhouse gases from human activities including industrial processes, fossil fuel combustion, and changes in land use, such as deforestation.
