UNEP has been active in disseminating information for decision-making and promoting awareness of climate change. In cooperation with the Convention's secretariat, UNEP is taking action to promote the implementation of Article 6 of the Convention, which addresses public awareness, education and training. As part of this effort, UNEP's Gl ...

Cooling factors
The amount of aerosols in the air has direct effect on the amount of solar radiation hitting the Earth's surface. Aerosols may have significant local or regional impact on temperature. Water vapour is a greenhouse gas, b...

Global atmospheric concentration of CO2
Atmospheric CO2 has increased from a pre-industrial concentration of about 280 ppmv to about 367 ppmv at present (ppmv= parts per million by volume). CO2 concentration data from before 1958 are from ice core measurements...

Freshwater stress
Today, the great pressure on water resources is rising human populations, particularly growing concentrations in urban areas. This diagram shows the impact of expected population growth on water usage by 2025, based on t...

Planets and atmospheres
A planet's climate is decided by its mass, its distance from the sun and the composition of its atmosphere. Mars is too small to keep a thick atmosphere. Its atmosphere consists mainly of carbon dioxide, but the atmosphe...

Potential dengue transmission in case of temperature rise
A warmer climate increases occasions of vector borne tropical diseases. This figure depicts weeks of potential dengue transmission under current temperature and 2°C and 4 °C warming. Presence of dengue virus, mosquito ve...

Forest composition case study in North America
Current and projected Ranges of Beech Trees in the US. A warmer climate may have significant effect on the forests. Decidous forests will probably move northwards and to higher altitudes, replacing coniferous forests in...

Sources of greenhouse gases
Shows the sources for greenhouse gases, contributing to climate change, and their relative radiative forcing effect (radiative forcing is the change in the balance between radiation coming into the atmosphere and radiati...

Emissions of CO2 - selected countries (1995)
The rich countries of the world historically have emitted most of the anthropogenic greenhouse gases since the start of the industrial revolution in the latter half of the 1700s. Per capita, the significant emissions sti...

Great weather and flood catastrophes over the last forty years
Some reports suggest that increase in climate variability or extremes has taken place in recent decades. However, there are inadequate data to determine whether such global changes have occurred consistently over the 20t...

UN Convention on Climate Change (UNFCCC)
The United Nations Framework Convention on Climate Convention is the foundation of global efforts to combat global warming. Opened for signature in 1992 at the Rio Earth Summit, its ultimate objective is the 'stabilizat...

Precipitation changes: trend over land from 1900 to 1994
Precipitation has increased over land at high latitudes of the Northern Hemisphere, especially during the cold season. Decrease in precipitation occurred in steps after the 1960s over the subtropics and the tropics from ...

CO2 emissions from land use change
Emissions of carbon dioxide due to changes in land use mainly come from the cutting down of forests and instead using the land for agriculture or built-up areas, urbanisation, roads etc. When large areas of rain forests ...

Six IPCC scenarios
The projection of future climate change depends partly on the assumptions made about future emissions of greenhouse gases and aerosol precursors and the proportion of emissions remaining in the atmosphere.

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...

Change in permafrost temperature in Fairbanks (Alaska)
With a doubling of atmospheric CO2, it is likely that there will be increases in the thickness of the active layer permafrost and the disappearance of most of the ice-rich discontinous permafrost over a century-long time...

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...
