A Street Cat Named Bob is the autobiography of James Bowen's life on the street, and the story of the friend he find's in a cat he names Bob. I must admit Bob never stops amazing me in this book, he is so intelligent and loyal! I'd love to meet him myself and I can see why everyone who encounters Bob loves him, too.
The Silurian atmosphere shows a decline from carbon dioxide values of 1200 ppm in the Upper Ordovician. Budyko and others (1987) (see Fig. 8) indicated atmospheric oxygen declines from about 65 percent of PAL (Present Atmospheric Level) to about 35 percent of PAL in the Late Silurian.
The atmosphere of Venus is the layer of gases surrounding Venus. It is composed primarily of carbon dioxide and is much denser and hotter than that of Earth. The temperature at the surface is 740 K, and the pressure is 93 bar, roughly the pressure found 900 m underwater on Earth. The Venusian atmosphere supports opaque clouds made of sulfuric acid, making optical Earth-based and orbital observation of the surface impossible.
