Carbon bad, but sulphur is good?
Flannery should come clean. Trials of dumping sulphur and other chemicals into the atmosphere from planes to create a 'sun shield', to encourage global dimming, has been going on for years. Distributing a substance like sulphur from planes is the very definition of a 'chem trail', and these test runs have been on show over Sydney in recent months, for anyone who bothers to look up occasionally.
But he says it may be necessary, as the "last barrier to climate collapse."
Professor Flannery says climate change is happening so quickly that mankind may need to pump sulphur into the atmosphere to survive.
The gas sulphur could be inserted into the earth's stratosphere to keep out the sun's rays and slow global warming, a process called global dimming.
"It would change the colour of the sky," Prof Flannery told AAP.
"It's the last resort that we have, it's the last barrier to a climate collapse.
"We need to be ready to start doing it in perhaps five years time if we fail to achieve what we're trying to achieve."
Prof Flannery, the 2007 Australian of the Year, said the sulphur could be dispersed above the earth's surface by adding it to jet fuel.
He conceded there were risks to global dimming via sulphur.
"The consequences of doing that are unknown."
The 'dimming' that Flannery talks of will be similar to the skies we've come to know well over some Australian cities in recent years. The cloud cover spreads early in the morning, and fills the sky, thin cloud but from horizon to horizon, blocking out much of the direct sunlight, and the cloud cover stays around for days. It's not the miserable grey of London skies, it's just...dim.
You will hear much, much more talk of using chemtrails to fight climate change very soon, if Flannery is speaking of such plans on behalf of international interests, and presumably he is.
ABC's Four Corners current affairs program ran a story on the dangers of global dimming in mid-2005. Despite what Flannery claims, scientists have a pretty good idea of what global dimming will do to the planet :
So more pollution will counter global warming, as long as it's sulphur pollution, but we need to cut carbon pollution and then increase the amount of sulphur in the atmosphere to encourage global dimming, which masks the full effects of global warming, which will destroy much of the world if it's not stopped, but global dimming is also destructive, but not as destructive as global warming, which is being held in check by current global dimming so we need to increase global dimming with sulphur while cutting down on carbon to stop global warming...or something.
Noticed less sunshine lately? Scientists have discovered that the amount of sunlight reaching the Earth’s surface has been falling over recent decades.
If the climatologists are right, their discovery holds the potential for powerful disruption to life on our planet. Already it may have contributed to many thousands of deaths through drought and famine.
Global dimming is a product of the fossil fuels that cause global warming. It is the result of tiny airborne pieces of soot, ash and sulphur compounds reflecting back the heat of the sun.
Scientists have also linked global dimming to the failure of rains in sub-Saharan Africa – and the catastrophic droughts that hit Ethiopia in the 1980s. They worry that the same thing will happen again in areas like Asia, home to billions of people.
The overriding concern expressed by climate scientists in this program is that our climate will be radically altered, rendering many parts of the planet uninhabitable - unless concerted action is taken to combat both global dimming and global warming.
I'm sure it makes perfect sense, if you're a professor.
