How else can we explain how the planet became uninhabitable from greenhouse gases?
I mean the accelerating CO2 increase must have been caused by humans because that is what the enviro-leftists say is happening here.
In reality it was the Sun (and it's growing strength as a star and proximity to Venus) that caused it to get warmer to the point of where it is now. Higher temps from the sun, mean more water vapour (a much more predominant greenhouse gas than CO2) which resulted in more CO2 released from the planet into the atmosphere.
"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.
The European Space Agency's (ESA) Venus Express, orbiting its prey since April 2006, seeks to explain this astonishing divergence.
Preliminary data from the probe reveal a Venus that is more Earth-like than once thought -- but not in ways that are reassuring.
At first blush, the two worlds, 42 million kilometres (26 million miles) apart at their closest points, could hardly be more different.
Earth's temperature range has remained largely stable and its atmosphere has maintained a balance of gases -- and this, with the precious water covering two-thirds of its surface, has allowed riotous biodiversity to flourish.
Venus' atmosphere, though, overwhelming comprises suffocating CO2 and a permanent blanket of clouds laced with sulphuric acid. Oxygen is nowhere to be found, nor is any water except in atmospheric traces.
Its surface hovers at 457 degrees Celsius (855 degrees Fahrenheit) and has a pressure equivalent, on Earth, to being a kilometer (3,250 feet) under the sea.
But this was not always so, says Hakan Svedhem, an ESA scientist and lead author of one of eight studies published on Wednesday in the British journal Nature.
Venus, he believes, may have been partially covered with water before it became doomed by global warming.
"Probably because Venus was closer to the Sun, the atmosphere was a little bit warmer and you got more water very high up," he told AFP.

The sun is also affecting temperatures here with it's variance, but never to the degree of Venus.
