Sedimentary Layers and Gas Migration Pathways
In this conceptual model, gas cannot easily reach the sediment surface of the continental slope without being transformed to gas hydrates or diverted upslope by impermeable hydrate-bearing sediment or glacial debris flow...

SLCP Climate Benefit - Avoided Global Warming
Rapid implementation of SLCP mitigation measures, together with measures to reduce CO2 emissions, would greatly improve the chances of keeping the Earth´s temperature increase to less than 2˚C relative to pre-industrial ...

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, Kazakhsta...

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 clima...

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, prima...

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...

BSR relative natural gas consumption
Graphics from the year 2000 Baltic 21 biannual indicator-based status report on sustainable development in the Baltic Sea Region (Baltic 21 Series No 1/2000). BSR relative natural gas consumption has remained constant fr...

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 ...

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...

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 concen...

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...

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 t...

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 cap...

Brazilian alcohol transport fleet and regional climate benefits
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 redu...

Use of renewables and combustible waste for energy production in 2001; Latin America and the Caribbean
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 aver...
