Extraterrestrial atmosphere reaching 70 m/s or more in the upper troposphere. The stratosphere and mesosphere extend from 65 km to 95 km in height. The thermosphere and exosphere begin at around 95 kilometres, eventually reaching the limit of the atmosphere at about 220 to 250 km. The air pressure at Venus' surface is about 92 times that of the Earth. The enormous amount of CO in the atmosphere creates a strong greenhouse effect, raising the surface temperature to around 470 °C, hotter than that of any other planet in the Solar System. The Martian atmosphere is very thin and composed mainly of
A Beautiful Planet lemur). The movie also reveals what the burning of the Brazilian rainforest looks like from space. Because rainforests are extremely concentrated biodiversity hotspots, the long plumes of smoke which the astronauts see rising from the Amazon jungle represent the extinction of species that might have led to the development of new pharmaceuticals, economically useful discoveries, or the advancement of scientific knowledge. The burning trees also add greenhouse gases to the atmosphere and curtail the capacity of the forest to reduce carbon dioxide and increase oxygen. Even though "A Beautiful Planet" contains a few dire warnings regarding climate change and environmental
