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 ...

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...

Main greenhouse gases
The table lists some of the main greenhouse gases (such as carbon dioxide, methane, and freons) and their concentrations in pre-industrial times and in 1994; atmospheric lifetimes; anthropogenic sources; and Global Warmi...

CO2 concentration in the atmosphere (1959-1998)
CO2 concentrations in the atmosphere have been measured at an altitude of about 4,000 meters on the peak of Mauna Loa mountain in Hawaii since 1958. The measurements at this location, remote from local sources of polluti...

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...

Climate scenarios for cereal production
The figure shows change in cereals production under three different GCM equilibrium scenarios (percent from base estimated in 2060). While there are still uncertainties about whether climate change will cause global agri...

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...

Potential impact of sea level rise: Nile Delta
Rising sea level would destroy weak parts of the sand belt, which is essential for the protection of lagoons and the low-lying reclaimed lands in the Nile delta of Egypt (Mediterranean Sea). The impacts would be very ser...

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...

Freshwater stress and risk
One study suggests that although global water conditions may worsen by 2025 due to population pressure, climate change could have a net positive impact on global water resources. NB! Note that other studies indicate tha...

Temperature and CO2 concentration in the atmosphere over the past 400 000 years
Over the last 400,000 years the Earth's climate has been unstable, with very significant temperature changes, going from a warm climate to an ice age in as rapidly as a few decades. These rapid changes suggest that clima...

Impact of Temperature Rise on Robusta Coffee in Uganda
Developing countries, whose economies often rely heavily on one or two agricultural products, are especially vulnerable to climate change. This graphic shows that with an increase of only 2 degrees Celsius, there would b...

Trends in the ice-breaking date in the Tornio river, Finland
The icebreaking date for the Tornio River in Finland has been recorded since 1693. With the increased greenhouse effect, impacts on the cryosphere are likely. One impact will be less ice on rivers and lakes. Freeze-up da...

Thinning of the Arctic sea-ice
Sea-ice draft is the thickness of the part of the ice that is submerged under the sea. Comparison of sea-ice draft data acquired on submarine cruises between 1993 and 1997 with similar data acquired between 1958 and 1976...

Sensitivity, adaptability and vulnerability
The potential impacts of climate change on the environment and socio-economic systems can be understood in terms of sensitivity, adaptability and vulnerability of the system, and this figure defines these terms.
