2.2.3 The effect of people and places

The footprints in the above Carbon Trust and National Statistics studies are for an average UK citizen. But footprints vary for different individuals and households. For example, another study showed that, on average, people aged 50 to 64 have heavier footprints than all other UK age groups, mainly due to their high spending on car and air travel, eating and drinking, and medical and financial services (Haq et al., 2007, p. 7).

The National Statistics study showed that the UK regions wi

Conclusion

Hydropower was the earliest means of commercial electricity generation, and currently dominates alternative electricity supply. However, its global capacity for large-scale exploitation is less than six times that currently installed.

Growth of hydropower is slow and its contribution to global electricity supply is falling. Both are due to economic factors, the slow pace of large-scale project construction, the remoteness of high-potential sites, and increasing resistance to the social

2.6.1 Weighing up the evidence: the full cast of suspects

Figure 36 (again adapted from the TAR) takes your thoughts on Question 11 on a stage. It gives estimates of the cumulative effect since pre-industrial times of the various climate change agents, with the contributions expressed in terms of radiative forcing. Note that the figure also includes yet another device for communicating the IPCC's confidence in a particular finding - an indication of the 'level of scientific understanding' that accompanies each estimate. This reflects the authors' su

1.2.4 Surgical methods of contraception

Surgical methods are by and large the most drastic and irreversible ones, ranging from castration to relatively untraumatic tube-tying. Because of the psychological and physiological side-effects, surgical removal of the testes or ovaries is not generally carried out for contraceptive reasons alone, although these operations may be carried out for other reasons, such as the presence of malignant tumours. Any kind of surgical sterilization can be physiologically traumatic for a woman, as it in

Battlefield: The Battle of Midway (3/12)
In June 1942, the most decisive naval battle of WWII was fought between the United States of America and the Japanese empire.

Victory or defeat depended not on the big guns of battleships, but on the carrier born bombers and torpedo bombers flying over vast tracks of ocean to seek and destroy their

Before the Industrial Revolution everything was produced by hand. Beginning in the 19th century, advances in manufacturing revolutionize the American way of life. A man named Samuel Slater memorized the plans for factories and brought them over to America. This started up the Industrial Revolution in America. Americans began moving into cities to work in factories. Assembly lines started appearing in factories which led to unskilled workers like women and children working. (2:31)
