Gas production, consumption and export Gas production, consumption and export
In terms of total world production, the Caspian accounts for 3.29% of oil production and 3.6% of gas production (BP 2009). The main focus of the oil and gas industry continues to be in the areas of Azerbaijan, Kazakhstan and Turkmenistan.

Climate feedbacks - the connectivity of the positive ice/snow albedo feedback, terrestrial snow and vegetation feedbacks and the negative cloud/radiation feedback Climate feedbacks - the connectivity of the positive ice/snow albedo feedback, terrestrial snow and vegetation feedbacks and the negative cloud/radiation feedback
Feedback refers to the modification of a process by changes resulting from the process itself. Positive feedbacks accelerate the process, while negative feedbacks slow it down. Part of the uncertainty around future climates relates to important feedbacks between different parts of the climate system: air temperatures, ice and snow albedo (reflection of the sun’s rays), and clouds. An important positive feedback is the ice and snow albedo feedback...

Major mineral fuel resources in Europe, Caucasus and Central Asia Major mineral fuel resources in Europe, Caucasus and Central Asia
Mineral fuels for electricity and heat generation take primarily two forms: fossil fuels in the form of oil, natural gas and coal, and uranimum ore for nuclear power. Oil and gas are distributed in different belts, primarily in the North Sea, Caucasus and Northern Russia. Coal in different forms is still an important fuel resource and resources are distributed over the region. Uranium resources are primarily in Ukraine and Central Asia.

Hydropower potential (theoretical possitibility for electricity generation) Hydropower potential (theoretical possitibility for electricity generation)
xHydropower, generating electricity through turbines, represents a clean and renewable energy source, but not without problems. Dams and reservoirs disrupt the natural flow, and may increase siltation and evaporation, in addition to severe impacts for wildlife, for instance migrating fish. The gross theoretical capability, presented in this map, represents a calculation based on the topography and precipitation in the countries, and is the amount...

SO2 air concentration SO2 air concentration
Sulfur dioxide (SO2) is a colourless gas with a sharp,irritating odour. It is produced from the burning of fossil fuels (coal and oil) and the smelting of mineral ores that contain sulfur. There are several areas in the Barents region that have very high amounts of SO2 levels that have caused environmental problems.

Kyoto protocol, cost of implementation Kyoto protocol, cost of implementation
The Kyoto Protocol is only a first step towards combating climate change. Drastic reductions of greenhouse gas emissions are required to avoid the most threatening consequences of global warming. Concerns are raised that the price for the economy will be too high, but studies indicate that there will only be a small reduction in GDP to reach the Kyoto targets and that it is possible to stabilize the concentration of CO2 at low costs. The GDP los...

Mitigating climate change: cost in 2050 (out of GDP) Mitigating climate change: cost in 2050 (out of GDP)
Global average GDP might be reduced by 1–4% if we reduce the emissions of CO2 so that we stabilize the concentration in the atmosphere at 450 ppmv. In 2003 the concentration was 375 ppmv. If we stabilise at higher concentration levels, the GDP reduction will be less. The projected mitigation scenarios do not take into account potential benefits of avoided climate change. Cost-effectiveness studies with a century time scale estimate that the mit...

Energy consumption, economic development and CO2 emissions; selected Latin America countries Energy consumption, economic development and CO2 emissions; selected Latin America countries
As a rule of thumb, economic growth is closely related to growth in energy consumption because the more energy is used, the higher the economic growth. However, it is possible to decouple energy consumption and economic growth to some extent.. More efficient use of energy may entail economic growth and a reduction in energy use. Energy efficiency may very well be an economic driving force. With an increasing use of sustainable energy sources, th...

CH4 emissions in 2000; Latin America and selected countries CH4 emissions in 2000; Latin America and selected countries
Since pre-industrial times, the atmospheric concentration of methane (CH4) has increased by 150%. Methane is a greenhouse gas that has a global warming potential that is 23 times stronger than CO2. (IPCC 2001) In 2000 the total world CH4 emissions was estimated at 6,000 million tonnes of CO2equivalents. In South America the emissions of CH4 per capita is almost twice the world average, while the per capita emissions in Central America and Caribb...

Change in precipitation for scenarios A2 and B2; Tropical America Change in precipitation for scenarios A2 and B2; Tropical America
When global surface temperatures increase, changes in precipitation and atmospheric moisture are very likely to increase: the hydrological cycle will be more active, and the atmosphere will increase its water holding capacity. Atmospheric water vapour is a climatically critical greenhouse gas, and more of it leads to a stronger greenhouse effect through natural feedback systems. As a rule of thumb, precipitation will increase in areas that alre...

CO2 emissions in the world and in Latin America and the Caribbean CO2 emissions in the world and in Latin America and the Caribbean
A comparison between the amount of CO2 emissions of the world and latin America and the Caribbean. Since pre-industrial times, the atmospheric concentration of greenhouse gases has grown significantly. The present level of carbon dioxide concentration (around 375 parts per million) is the highest for 420,000 years, and probably the highest for the past 20 million years. CO2 is the greenhouse gas that contributes most to the enhanced greenhouse e...

Tropical hydropower dams as greenhouse sources Tropical hydropower dams as greenhouse sources
Large tropical hydropower reservoirs in Latin America may have a potential adverse impact on the climatic system through releasing greenhouse gases into the atmosphere. Submerging large areas of land and tropical vegetation under water and fluctuations in water level promote physical-chemical processes that decompose the organic matter and generate methane and carbon dioxide emissions. In the initial years of operation, emission levels are especi...

This graphic displays greenhouse gas emissions per capita in Latin America and the Caribbean compared to countries in the Organisation for Economic Co-operation and Development (OECD).

In Brazil there are noticeable benefits for using alcohol as a fuel over traditional gasoline. This graphic illustrates the reduction in use of fossil fuels (gasoline) in favor of ethanol/alcohol. This has lead to a reduction in emissions of CO2 emissions, as illustrated by the bottom chart.

Approximately 12 % of the world’s energy supply comes from renewable energy sources (biomass, waste and other renewables, excluding hydropower). The average renewable share in Latin America is higher than the world average,. But even if the energy supply from renewables will increase in Latin America, the percentage share of renewables of total energy supply is projected to decrease in the years to come. (World Energy Outlook 2004). Latin Ameri...

Sea level rise due to the melting of mountain and subpolar glaciers Sea level rise due to the melting of mountain and subpolar glaciers
Oceans change as a result of the impact of climatic variability on glaciers and ice caps that further contributes to fluctuation sin sea leve. Observational and modelling studies of glaciers and ice caps indicate an average sea level increase of 0.2 to 0.4 mm/yr during the 20th century. Since the Last Glacial Maximum about 20,000 years ago, sea level has risen by over 120 m at locations far from present and former ice sheets, as a result of los...

Cooling factors 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, but at the same time the upper white surface of clouds reflects solar radiation back into space. Albedo - reflections of solar radiation from surfaces on the Earth - creates difficulties in exact calculations. If e.g. the polar ice...
