Atmosphere of Venus water and subsequent rise of the levels of other greenhouse gases. Despite the harsh conditions on the surface, the atmospheric pressure and temperature at about 50 km to 65 km above the surface of the planet is nearly the same as that of the Earth, making its upper atmosphere the most Earth-like area in the Solar System, even more so than the surface of Mars. Due to the similarity in pressure and temperature and the fact that breathable air (21% oxygen, 78% nitrogen) is a lifting gas on Venus in the same way that helium is a lifting gas on
Suicide in the United Kingdom (4 per cent). Hanging is the most common method used by women, closely followed by self poisoning. Inhalation of domestic gas was the most common method of suicide during the mid-twentieth century.

Later, suicide by inhalation of carbon monoxide from car exhausts became common, but has declined since the introduction of catalytic converters. Age-standardised rates generally fell between 1981 and 2007, with rates in subsequent years increasing to reach a peak of 11.1 deaths per
