It is estimated that there are over a billion personal computers in the world at present. In developed countries these have an average life span of only 2 years. In the United States alone there are [..]
The changes in cold-season mean temperatures over Arctic land regions are broken into three latitudinal bands for each region, as shown on the small map (which has an outer rim of 50° N). Error bars [..]
The water resources of small islands and low-lying coastal areas are very susceptible to sea-level rise. This figure illustrates the direct impacts on the water resources sector, as well as the [..]
By far the largest area of glaciers and ice fields are found in Canada (about 201 000 km2), followed by Alaska (about 75 000 km2) with about 700 km2 in the rest of the USA. Glaciers and ice fields [..]
Thirty reference glaciers with almost continuous
mass balance measurements since 1975
show an average annual mass loss of 0.58 m water
equivalent for the past decade (1996–2005), which is
more [..]
Glaciers and ice caps form around the world where snow deposited during the cold/humid season does not entirely melt during warm/dry times. This seasonal snow gradually becomes denser and transforms [..]
In spring, the ice is snow-covered and there is very little open water. Most sunlight is reflected, but some is absorbed. This absorbed sunlight leads to melting, which in turn reduces the ice albedo [..]
The Basel Convention has before it an amendment which would ban the export of hazardous waste for disposal to developing countries. Some countries (for example those in the European Union) have [..]
It is estimated that there are over a billion personal computers in the world at present. In developed countries these have an average life span of only 2 years. In the United States alone there are [..]
Mines use toxic chemicals including cyanide, mercury, and sulphuric acid, to separate metal from ore. The chemicals used in the processing are generally recycled, however residues may remain in the [..]
Hazardous waste needs to be monitored and controlled from the moment the waste is generated until its ultimate disposal. Proper hazardous waste control requires a plan to reduce the amount of waste [..]
To highlight the distribution of wealth and power in the world of today, this cartogram sizes the countries according to their relative financial status, here presented through gross domestic product [..]
A generalized diagram of how multinational networks exploit and natural resources in developing countries through numerous temporary subsidiaries and the use of corruption and security firms to ensure [..]
Waste collection is a basic public service performed for everyone in OECD countries. Everyone? Well, a closer look reveals that this is not the case for a significant number of people. If these [..]
Waste, including extremely hazardous waste like radioactive
material, toxic heavy metals and poisonous PCBs are routinely being loaded into trucks, and transported across continents. Some is loaded [..]
