Malaria risk and climate change
Plasmodium vivax, with the Anopheles mosquito as a vector, is an organism causing malaria. The main climate factors that have bearing on the malarial transmission potential of the mosquito population are temperature and ...

Radiative forcing - energy balances and the greenhouse effect
Radiative forcing is the change in the balance between radiation coming into the atmosphere and radiation going out. A positive radiative forcing tends on average to warm the surface of the Earth, and negative forcing te...

Climate change and vector-borne diseases
Climate change and altered weather patters would affect the range (both altitude and latitude), intensity, and seasonality of many major tropical vector-borne and other infectious diseases - such as malaria and dengue fe...

Trends in global temperatures
The figure shows the combined land-surface air and sea surface temperatures (degrees Centigrade) 1861 to 1998, relative to the average temperature between 1961 and 1990. The mean global surface temperature has increased...

Temperature trends and projections
Using the IS92 emission scenarios, projected global mean temperature changes relative to 1990 were calculated up to 2100. Climate models calculate that the global mean surface temperature could rise by about 1 to 4.5 cen...

Scenarios of sea level rise, now - 2100
Using the IS92 emission scenarios, projected global mean sea level increases relative to 1990 were calculated up to 2100. Taking into account the ranges in the estimate of climate sensitivity and ice melt parameters, and...

Sea level rise due, past and scenarios due to global warming
Over the last 100 years, the global sea level has risen by about 10 to 25 cm. Sea level change is difficult to measure. Relative sea level changes have been derived mainly from tide-gauge data. In the conventional tide-g...

Climate change impact on mountain vegetation zones
The figure shows a comparison of current vegetation zones at a hypothetical dry temperate mountain site with simulated vegetation zones under a climate-warming scenario. Mountains cover about 20% of the Earth's continent...

CO2 emissions from industry
This map depicts the unequal distribution of industry in the world. The significant part of carbon dioxide emissions comes from energy production, industrial processes and transport. The industrialised countries conseque...

The carbon cycle
The global carbon cycle shows the carbon reservoirs in GtC (gigatonne= one thousand million tonnes) and fluxes in GtC/year. The indicated figures are annual averages over the period 1980 to 1989. The component cycles ar...

World ocean thermohaline circulation
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. W...

Projected changes in CO2 and climate: assumptions in the IPCC 1992 scenarios
Projected anthropogenic CO2 emissions from fossil fuel use, deforestation and cement production are shown for some of the IPCC emission scenarios. The highest emission scenario - IS92e - assumes moderate population grow...

Potential climate change impacts
If greenhouse gas concentrations keep rising, climatic changes are likely to result. Those changes will potentially have wide-ranging effects on the environment and socio-economic and related sectors, such as health, agr...

IPCC and UNFCCC - Institutional framework
In 1988, UNEP and WMO jointly established the Intergovernmental Panel on Climate Change (IPCC) as concern over changes in the climate became a political issue. The purpose of the IPCC was to assess the state of knowledge...

Greenhouse effect
Human activities are causing greenhouse gas levels in the atmosphere to increase. This graphic explains how solar energy is absorbed by the earth's surface, causing the earth to warm and to emit infrared radiation. The g...
