Venus holds warning for Earth
30 November 2010
A mysterious high-altitude layer of sulphur dioxide discovered by ESA’s Venus Express has been explained. As well as telling us more about Venus, it could be sending a warning to those on Earth seeking to inject our atmosphere with sulphur droplets in an attempt to mitigate climate change.
Venus is blanketed in sulphuric acid clouds that block our view of the surface. The clouds form at altitudes of 50–70 km when sulphur dioxide from volcanoes combines with water vapour to make sulphuric acid droplets. Any remaining sulphur dioxide should be destroyed rapidly by the intense solar radiation above 70 km.
So the detection of a sulphur dioxide layer at 90–110 km by ESA’s Venus Express orbiter in 2008 posed a complete mystery. Where did that sulphur dioxide come from?
Now, computer simulations by Xi Zhang, California Institute of Technology, USA, and colleagues from America, France and Taiwan show that some sulphuric acid droplets may evaporate at high altitude, freeing gaseous sulphuric acid that is then broken apart by sunlight, releasing sulphur dioxide gas.
“We had not expected the high-altitude sulphur layer, but now we can explain our measurements,” says Håkan Svedhem, ESA’s Venus Express Project Scientist.
“However, the new findings also mean that the atmospheric sulphur cycle is more complicated than we thought.”
As well as adding to our knowledge of Venus, this new understanding may be warning us that proposed ways of mitigating climate change on Earth may not be as effective as originally thought.
Nobel prize winner Paul Crutzen has recently advocated injecting artificially large quantities of sulphur dioxide into Earth’s atmosphere at around 20 km to counteract the global warming resulting from increased greenhouse gases.
The proposal stems from observations of powerful volcanic eruptions, in particular the 1991 eruption of Mount Pinatubo in the Philippines that shot sulphur dioxide up into Earth’s atmosphere. Reaching 20 km in altitude, the gas formed small droplets of concentrated sulphuric acid, like those found in Venus’ clouds, which then spread around Earth. The droplets created a haze layer that reflected some of the Sun’s rays back into space, cooling the whole planet by about 0.5°C.
However, the new work on the evaporation of sulphuric acid on Venus suggests that such attempts at cooling our planet may not be as successful as first thought, because we do not know how quickly the initially protective haze will be converted back into gaseous sulphuric acid: this is transparent and so allows all the Sun’s rays through.
“We must study in great detail the potential consequences of such an artificial sulphur layer in the atmosphere of Earth,” says Jean-Loup Bertaux, Université de Versailles-Saint-Quentin, France, Principal Investigator of the SPICAV sensor on Venus Express. “Venus has an enormous layer of such droplets, so anything that we learn about those clouds is likely to be relevant to any geo-engineering of our own planet.”
In effect, nature is doing the experiment for us and Venus Express allows us to learn the lessons before experimenting with our own world.
What madness, that scientists are willing to to consider spraying known toxic carcinogens into the atmosphere. Aside from the chemtrail operations, the chemtrail/geo-engineering patents, aircraft still use leaded fuel, that falls onto the subjects on the earth who breathe the known toxic carcinogens. Biodegradable hemp ethanol is the solution to the toxic fuel issue. Why are aircraft even using fuel for propulsion anyway?
All of the money, energy, resources in the world that have gone into this economic crisis via bank bailouts for the bankrupt banks was enough to create:
I link all the pollution with our earth and venus in my film Peak Oil, Economic Collapse are a Fraud. Maybe venus was like earth and their civilization destroyed their atmosphere the same way human kind is on earth? I am not saying I know that is true, I am considering the possibility. The planet venus presents human kind with a mystery to think about.
Think about this quote “We must study in great detail the potential consequences of such an artificial sulphur layer in the atmosphere of Earth,” says Jean-Loup Bertaux, Université de Versailles-Saint-Quentin, France.
What about an artificial layer of aluminum, barium and more? None of this is good for anything living on this planet. Why are Nobel prize winners turning out to be nothing more than mad scientists, war mongers, liars and crooks? It is a shame Nobel’s name is being used to promote such devolved human values.
What in the world are they spraying?
