Warming of the earth's surface
Climate projections for Latin America and the Caribbean indicate that temperature increases will vary according to the particular emissions scenario and country or region concerned. According to the A1B climate change sc...

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...

Energy resources, production and transportation
Energy is vital for the internal and external security of all three countries (see figure). A secure, affordable domestic energy supply is critical to economic development, particularly in energy hungry industrial sector...

Environment and security issues in Ukraine
Compared to its neighbours, Ukraine has a very low Environmental Sustainability Index (ESI) (ranking 108 out of 146 countries; Esty et al. 2005). This is primarily due to the high energy and pollution-intensity of its in...

Energy - environment - security interactions
Recently energy demand in the region has reached and surpassed the 1991 level at the same time as the world oil prices have increased dramatically. Russia, for its part, has started a reappraisal of the political and eco...

Environment and security issues in Moldova
Since water resources are of particular importance to Moldova, water pollution is viewed as a nationally significant threat. Moldova does not have large lakes, and all its larger rivers originate outside its borders. the...

Nuclear energy is not a clean alternative The legacy of the Soviet Union's nuclear activities
Even though the nuclear industry does not significantly contribute to greenhouse gas emissions, it is a disputable alternative to fossil fuels. In the former USSR people and the environment still have to cope with the ...

Energy cost of various construction materials
CO2 emissions are not directly deducible from energy costs. Concrete for instance is a very CO2-intensive material due to the emissions from chemical processes involved in its production, despite the relatively low energ...

Strategic options for climate change mitigation Global cost curve for greenhouse gas abatement measures
This graphic attempts to show 'all in one': the various measures for greenhouse gas reduction with both reduction (in CO2 equivalent) and cost (in Euros) quantified. Read from left to right it gives the whole range of s...

Some examples of the effect of individual behaviour on greenhouse gas emissions in France
The area of the squares is proportionate to the annual reduction in emissions in million tonnes of CO2 equivalent. Estimated values calculated by France's Environment Institute (Ifen), drawing on various sources: Mani...

Climate Change Performance Index 2008
The Climate Change Performance Index developed by Germanwatch is calculated using three weighted indexes: *Emissions trends for energy, transport, industry and residential account for 50 % of total rating; *A countr...

Biological oxygen demand - BOD: 1976-2008
The availability of oxygen is one of the most important indicators of the condition of a water body, because dissolved oxygen, or DO, (the amount of oxygen dissolved in water) is necessary for most aquatic organisms, inc...

Industrial areas and seasonal zones of oxygen depleted waters
This graphic illustrates the strong link between areas with high densities of industrial activity and zones of seasonally oxygen-depleted waters. There is a strong link between areas with high densities of industrial ac...
