Easy: you pay 25 quid; they take it, and wipe their … with it

Kapish?

Perhaps it briefed Carter-Ruck !
It was discovered that chlorine emissions from a mountain (can`t remember the name) was the cause of the hole, not CFC's. The whole campaign was dropped without explanation but the CFC regulations were kept in place.

Mount Erebus.
(The one on which the NZ jet crashed during a fly past, killing 257, in Nov 1979)
Another brilliant thing about it was that the ozone layer had only been discovered relatively short time before, so no one know whether it was "supposed" to have a hole in it, or not.

Perhaps it is time that a solution was found for the excess CO2. I don`t mean cutting emissions and planting more trees or any of those planet friendly options. What we need is an answer which accepts the way things are not how they should be. The cure for venereal disease was not getting rid of sex but antibiotics.

(Just as well !)

One possibility is seeding the oceans of the world with iron in which they are extremely deficient. Look at the amount of life round every sea-bed wreck.
The theory is that this would cause an algal bloom, and foraminferae, which would make their tiny shells and fall to the floor of the ocean, thereby locking up CO2
in the form of calcium carbonates, as happened in the Jurassic, 240 - 170m years ago.
I realise that this is trying to turn the clock back, but the alternative might be to start the migration of peoples to places which are going to be more temperate

It`s more of that kind of thinking that`s needed. I think a lot more could be considered if a multi discipline approach was applied. We have far too many specialists these days with every issue neetly pigeon-holed. Gone are the days of the polymath.

Climate change is natural and normal. We are not long out of an ice age and given the planet is approx 4.5 billion years old there will be temperature increases and temperature drops, at one point the whole planet was covered in ice to a depth of several miles (Snowball Earth) Temps will climb again wherether we try and stop it or not, Mother nature will do her 'thang' whilst life on the planet will have to acclimatise or go extinct.

Out planet like the rest of the solar system is affected by changes in the sun, either sun spot activity or as it ages, expamsion ino a snazzy red giant which will probably engluf us turning us to a nice cinder if anything survives at all before the sun uses all it's fuel up and shrinks to become a white swarf.

Nothing we do will stop nature taking it's course, we can't stop sunspots forming, we can't stop volcanoes erupting, we can't even control the wind, how are we going to control a whole planet's climate?

Tinkering with the weather is a bad idea anyway as if we cause it to rain in one place instead of another there will be a chain reaction with untold consequences as it is all interlinked and reliant on itself.

it's like  building flood barriers to prevent flooding on a flood plain.

When heavy rain arrives, the river can't flood natually as it should, the result is the water builds up and backs up causing flooding where there was no flooding before or the water speeds down the river damaging  the flood defences and  breaking out durther down river flooding places that never flooded before.

new defences are build causing the problem to spread upstream and down and we end up with rivers fenced in by concrete down to the sea, resulting in loss of wildlife and nutrients in the soil and considerably environmental damage all round evwen to affecting sealife.

We cannot change outr climate no matter what we do,nor should we even try. Instead we should and must learn to adapt the same ous life before us did. if we don't adapt we will become extict ( we'll die out anyway in another 5 billion years or so when the sun expamds and planets caramelise.

Recently on Japanese TV, one of their universities has developed a prototype to deal with excess CO2 produced from power producing plants.
The waste CO2 is captured in containers, then sea water is pumped in as a fine spray.
This readily absorbs the CO2.
This liquid then passes through 'seaweed growing' chambers, the seaweed grows and produces 'ethanol' which is then used to power the power plant to greatly reduce the amount of coal formerly used.
The seaweed is then used for food consumption, and presumably, if any excess should occur I suppose it could be used as fertiliser. big grin

Anyone familiar with James Lovelock's Gaia Theory of the earth as a self-regulating organism?

I have highlighted the last line but one in red. I love irony and rarely has it proved as much fun as in this case. Schadenfreude!
 


Antarctic rescue of Akademik Shokalskiy ship completed





The BBC's Andrew Luck-Baker describes his rescue experience

Rescuers in Antarctica have safely transferred all 52 passengers stranded on the ice-bound research vessel Akademik Shokalskiy.

The Australian rescue operators said the scientists and tourists were now all aboard the ship Aurora Australis.

They were flown there in groups by a helicopter from a Chinese ice-breaker.

The Shokalskiy has been trapped since 24 December. Its 22 crew are expected to remain on board to wait until the vessel becomes free.

The Shokalskiy was trapped by thick sheets of ice driven by strong winds, about 1,500 nautical miles south of Hobart - the capital of the Australian state of Tasmania.

The vessel was being used by the Australasian Antarctic Expedition to follow the route explorer Douglas Mawson travelled a century ago.

'White-knuckle ride'

"We've made it to the Aurora australis safe & sound. A huge thanks to the Chinese & @AusAntarctic for all their hard work!," expedition leader Chris Turney tweeted.

The helicopter belongs to the Chinese icebreaker, Xue Long, and each flight took about 45 minutes, round-trip.


The first group of passengers is airlifted out



The ship's passengers sang songs on New Year's Day as they awaited rescue

The Akademik Shokalskiy has been trapped since Christmas Eve



The BBC's Andrew Luck-Baker, who was on board the Akademik Shokalskiy, says the 15-minute one-way flight was a "white-knuckle ride".

The passengers were taken to an ice floe next to the Aurora Australis and then ferried on to the ice-breaker by a small boat.

Our correspondent says the Russian crew staying behind could be on the Akademik Shokalskiy for weeks before the pack ice clears.

The Australian Maritime Safety Authority's (Amsa) Rescue Co-ordination Centre, which was overseeing the operation, had earlier said it was unlikely the rescue would go ahead on Thursday as hoped because of the sea-ice conditions.

But it later reported: "Aurora Australis has advised Amsa that the 52 passengers from the Akademik Shokalskiy are now on board."

The passengers are not expected back in Tasmania until mid-January.

Several attempts to break through to the ship by sea - by the Xue Long, Aurora Australis and French-flagged L'Astrolabe - failed because of the thickness of the ice.

Andrew Luck-Baker says the Aurora Australis, although big, was simply not up to the task and there is speculation two larger vessels may be coming to the area in the weeks to come.

Despite being trapped, the scientists continued their experiments, measuring temperature and salinity through cracks in the surrounding ice.

One of the aims was to track how quickly the Antarctic's sea ice was disappearing.

The ship had plenty of stocks and was never in danger.
