Arctic sea routes - Northern sea route and Northwest passage Arctic sea routes - Northern sea route and Northwest passage
Sea routes along the edges of the Arctic ocean, or rather along the coasts of Northern Canada and Russia, holds potential for decreasing the number of days in shipping goods from the Pacific to Atlantic coasts in Europe and North America, and vice versa. In addition, this could provide a means to transport natural resources, such as oil and gas, extracted in the Arctic. Currently these routes have not been possible to use this, due to the ice con...

CO2 concentration in the atmosphere (1959-1998) 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 pollution, have clearly shown that atmospheric concentrations of CO2 are increasing. The mean concentration of approximately 316 parts per million by volume (ppmv) in 1958 rose to approximately 369 ppmv in 1998. The annual variation is d...

Africa: Stockholm convention on persistent organic pollutants (POPs) Africa: Stockholm convention on persistent organic pollutants (POPs)
The process initiated by UNEP in 1995, materialised as the Stockholm convention in May 2001. The convention bans chemicals such as chlordane, DDT and PCB and other organic pesticides and industrial chemicals, as well as establishing precautionary approaches for the future. Most African countries are using agents, such as DDT, for control of disease vectors and pests under exemptions.

Emissions of carbon dioxide, in Africa and selected OECD countries Emissions of carbon dioxide, in Africa and selected OECD countries
Africa represents only a small fraction, 3.6%, out of the total carbon dioxide (CO2) emissions per year, yet 14% of the population of the world lives here. The emissions per inhabitant in Libya, the Seychelles and South Africa are on the level of the lowest among OECD countries with the other African countries trailing lower behind them. Regionally, emissions (both per capita and in total) are at their highest in North Africa and in the country o...

Pesticides stockpiles in Africa Pesticides stockpiles in Africa
Mountains of obsolete pesticides are stockpiled in Africa. Problems with labelling, storage, and the supply of unsuitable products, means that they sit around unused, some for as long as 40 years. They include poisons long ago banned (e.g. DDT, aldrin, dieldrin, chlordane, heptachlor, and others). In some cases the pesticides have leaked from damaged containers. Unable to dispose of them safely the likelihood is that the piles will continue to gr...

Paper and paperboard production Paper and paperboard production
Though it is based on wood, a natural renewable resource, the pulp and paper industry is one of the worst sources of pollution. It absorbs more than 40 per cent of all timber felled worldwide. Despite the development of digital communications tools global paper production is expected to increase by 2.2 per cent a year from 330 million tonnes at present to 440 million tonnes worldwide by 2015. The main growth areas are Asia and Eastern Europe, but...

Oil exports from inland Eurasia via the Mediterranean Sea, current and projected (2002 and 2010) Oil exports from inland Eurasia via the Mediterranean Sea, current and projected (2002 and 2010)
The Black and Mediterranean Seas are one of the main outlets for transporting fuel resources that have been extracted around the Caspian Sea region and from further inland. Oil is transported in pipelines to the ports on the Black Sea. Forecast project a dramatic increase by 2010, including the opening of a new port in Turkey.

Mine and industrial site in Koshkar-Ata, Kazakhstan Mine and industrial site in Koshkar-Ata, Kazakhstan
Much of the area near Koshkar-Ata Lake in Kazakhstan, just off the shore of the Caspian Sea, has been severely polluted due to mining activities of uranium phosphate. The area is also affected from chemical plants and metallurgic industries. The pollutants are quickly making there way to the Caspian Sea.

Discharge of pollutants in the Caspian Sea - mercury and cadmium Discharge of pollutants in the Caspian Sea - mercury and cadmium
Mercury and Cadmium are classified as toxic metals, and are persistant pollutants in the environment, that stays in the system and is accumulated through the food chains. The main release of these pollutants are on the west coast of the Caspian Sea, off the coast of Russia and Azerbaijan.

Origin and destination of selected invasive/alien species Origin and destination of selected invasive/alien species
Invasive and alien species that are brought into a new environment, either on purpose or by accident, can quickly exploit ecological niches that are not fully covered by indigenous (local) species. They will then quickly spread and outcompete the local wildlife.

Sampled sediments in the Caspian Sea show that the accumulation is at its worst in the south and southwestern shores of this inland sea, off the shores of Iran and Azerbaijan. Sampled pollutants presented in this map are pesticides (persistant organic pollutants Lindane and DDT - POPs), and the heavy metals Chromium and Nickel.

How the comb-jelly (Mnemiopsis leidyi) is spreading through European seas (invasive species) How the comb-jelly (Mnemiopsis leidyi) is spreading through European seas (invasive species)
The most threatening event for the Caspian ecosystem was the arrival of the North American comb jelly (Mnemiopsis leidyi). It was brought accidentally to the Caspian in the ballast water of oil tankers. Invasive and alien species can exploit ecological niches that are not currently occupied, and spread rapidly, out-competing indigenous species.

Emissions and energy scenarios by source Emissions and energy scenarios by source
Despite the Kyoto protocol and increased concern over the consequences of climate change, world wide emissions of CO2 continues to grow. According to the International Energy Agency (IEA) world total CO2 emissions will increase by 62% from 2002 – 2030. More than two-thirds of the increase will come from developing countries. They will overtake the OECD as the leading contributor to global emissions early in the 2020s. Despite the strong increase ...

Kyoto protocol, projected 2010 target status Kyoto protocol, projected 2010 target status
According to the projections each country has sent to the UNFCCC Secretariat, 14 countries will reach their targets in 2010. Some of the countries that had reached their targets in 2002 will increase their emissions between 2002-2010, while others like Germany will decrease and reach their target in 2010. The number of countries reaching their targets is pretty stable. Projection data for some of the countries that reached their targets in 2002 a...

Past and future CO2 concentrations Past and future CO2 concentrations
Since pre-industrial times, the atmospheric concentration of greenhouse gases has grown significantly. Carbon dioxide (CO2) concentration has increased by about 31%, methane concentration by about 150%, and nitrous oxide concentration by about 16% (Watson et al 2001). 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.

Ok Tedi mine Ok Tedi mine
The Ok Tedi mine is located high in the rain forest covered Star Mountains of Papua New Guinea. Prior to 1981 the local Wopkaimin people lived a subsistence existence in one of the most isolated places on earth. That was before the 10 000 strong town of Tabubil suddenly appeared in the middle of their community. The Ok Tedi mine was built on the world’s largest gold and copper deposit (gold ore capping the main copper deposit).

Biodiversity loss: state and scenarios 2006 and 2050 Biodiversity loss: state and scenarios 2006 and 2050
These projections of biodiversity loss from 2000 to 2050 were produced by the GLOBIO consortium for UNEP's Global Environment Outlook 4. Across the GEO scenarios and regions, global biodiversity continues to be threatened, with strong implications for ecosystem services and human well-being. All regions continue to experience declines in terrestrial biodiversity in each of the scenarios. The greatest losses are seen in Markets First, followed by ...
