Venus inferno due to 'runaway greenhouse effect', 
say scientists
_____________________________


29 Nov -7 - Once styled as Earth's twin, Venus was transformed from a haven for water to a fiery hell by an unstoppable greenhouse effect, according to an investigation by the first space probe to visit our closest neighbour in more than a decade

Like peas in a cosmic pod, the second and third rocks from the Sun came into being 4.5 billion years ago with nearly the same radius, mass, density and chemical composition.

But only one, Earth, developed an atmosphere conducive to life. The other, named with unwitting irony after the Roman goddess of love, is an inferno of carbon dioxide (CO2), its surface hot enough to melt steel.

But this was not always so, says Hakan Svedhem, an ESA scientist. Venus, he believes, may have been partially covered with water before it became doomed by global warming.

              Uh huh. And the global warming on Venus was caused by humans, 
              I presume. Oh well, include the words ‘global warming’ in your proposal,
              and you’ll get funding.
