World's Biggest Atlas

Copies of the largest world atlas ever produced have gone on sale at an earth-shattering price of £2,000 each.

Dubbed “the ultimate book about our world”, the luxurious, limited edition Earth is hand-bound in leather with gilded edges and silver-plated corners.

The atlas and its case together weigh 30kg – more than the maximum many airlines set passengers for their baggage allowance.

The 576 pages contain 154 maps and 800 photographs backed with detailed descriptions of every country’s geography, history and culture. Lying closed, the atlas takes up a third of a square metre with four gatefolds opening out to two square metres each.

Ten cartographic experts at the British map company Global Mapping spent eight months compiling Earth with more than 100 overseas colleagues including fellow map makers, geographers and oceanographers. They worked with detail from a continuously updated world database of digital mapping.

Global Mapping’s Alan Smith said: “We all had to keep to the same, consistent specification to make sure everything tied in universally from the way we shaded hills to the presentation of political geography. The sheer physical size of the atlas is amazing. The overall content, including the maps, text and photographs, is very much more detailed than any other atlas ever produced.”

Only 3,000 hand-numbered copies of Earth have been made – one for every 3.3 million people in the world. The atlas is expected to appeal to specialist collectors, libraries, rich individuals with a penchant for mapping and companies seeking lavish, once-in-a-lifetime corporate gifts. Taking the exclusive level even higher, one thousand copies from the print run have had their covers redone in gold leather with gold plated corners at the request of distributors in the Middle East.

Earth is the brainchild of Australian map publisher Gordon Cheers who has already received several hundred orders for copies. He described it as “a time capsule of where we are in the world today”.

The atlas may be impressive but its 30kg weight still pales into insignificance when compared to the mass of the planet itself – estimated at an unpronounceable 6,000,000,000,000,000,000,000,000 kg.

Climate Change - Cities Are The Solution, Not The Problem


Cities are unfairly blamed for greenhouse gas emissions by misguided politicians and well-meaning people who listen to them, and this threatens efforts to truly impact climate change, warns a study in the October 2008 issue of the journal Environment and Urbanization. The paper says cities are commonly blamed for 75 to 80 percent of emissions but that the true value is around half that and the potential for cities to help address climate change is being overlooked because of this error. 

United Nations agencies, former US President Bill Clinton’s climate change initiative and New York Mayor Michael Bloomberg have all claimed that between 75 and 80 per cent of emissions come from cities even though data from the Intergovernmental Panel on Climate Change (IPCC) shows that only 40 percent of all greenhouse gases are from human activities generated within cities.

“Blaming cities for greenhouse gas emissions misses the point that cities are a large part of the solution,” says the paper’s author, David Satterthwaite, a Senior Fellow at the International Institute for Environment and Development (IIED). “Well planned, well governed cities can provide high living standards that do not require high consumption levels and high greenhouse gas emissions.”

Satterthwaite says agriculture and deforestation account for another 30 percent of greenhouse gas emissions and the final 30 percent are from heavy industry, coal, oil or gas fuelled power stations located in non-metropolitan areas and wealthy households, like politicians live in when they are misstating data.

The paper also highlights how it can be misleading to allocate greenhouse gas emissions to places at all. For instance, emissions from power stations should be allocated to those that consume the electricity, not the places where the power stations are located. Emissions generated by industries would therefore be shared by the person consuming the goods the industries produce. 



“Consumer demand drives the production of goods and services, and therefore the emission of greenhouse gases,” says Satterthwaite. “Allocating emissions to consumers rather than producers shows that the problem is not cities but a minority of the world’s population with high-consumption lifestyles. A large proportion of these consumers live not in cities but in small towns and rural areas.” 

Allocating greenhouse gas emissions to consumers increases the share of global emissions from Europe and North America, which makes self-loathing activists happy, but also clarifies the very low emissions per person of most city inhabitants in Africa, Asia and Latin America.

In general, wealthy people outside cities are responsible for more greenhouse gas emissions than those in cities as they have larger homes that need to be heated or cooled, more automobiles per household and greater automobile use.

“The way cities are designed and run can make a big difference,” says Satterthwaite. “Most cities in the United States have three to five times the gasoline use per person of most European cities but not three to five times the living standards.”

Satterthwaite points out that cities offer many opportunities to reduce per capita greenhouse gas emissions, such as by promoting walking, bicycling and public transport and having building designs that require much less energy for heating and cooling.

“Achieving the needed reductions in greenhouse gas emissions worldwide depends on seeing and acting on the potential of cities to combine a high quality of life with low greenhouse gas emissions,” he says.

The freshwater biome


Freshwater is defined as having a low salt concentration — usually less than 1%. Plants and animals in freshwater regions are adjusted to the low salt content and would not be able to survive in areas of high salt concentration (i.e., ocean). There are different types of freshwater regions:

Ponds and lakes
Streams and rivers
Wetlands

The Birth of Eart's Moon: Giant Impact Theory

At the time Earth formed 4.5 billion years ago, other smaller planetary bodies were also growing. One of these hit earth late in Earth’s growth process, blowing out rocky debris. A fraction of that debris went into orbit around the Earth and aggregated into the moon.
