In our Solar System, which planet is the hottest, with a mean surface temperature of around 464 degrees ?
Venus or roughly the pressure found underwater on Earth. Venus is by far the hottest planet in the Solar System, with a mean surface temperature of , even though Mercury is closer to the Sun. Venus is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light. It may have had water oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect. The water has probably photodissociated, and the free hydrogen has been swept into interplanetary space by the
Six Degrees: Our Future on a Hotter Planet Six Degrees: Our Future on a Hotter Planet Six Degrees: Our Future on a Hotter Planet (358 pages), is a 2007 (2008 in USA) non-fiction book by author Mark Lynas about global warming. The book looks and attempts to summarize results from scientific papers on climate change. The first chapter describes the expected effects of climate change with one degree (°C) increase in average global temperature since pre-industrial times. The second chapter describes the effects of two degrees average temperature and so forth until Chapter 6 which shows the expected effects of six degrees(°) average global temperature. The effects are
