Man can’t help himself, he just keeps screwing up.

A new threat to the Ozone Layer has been discovered; well, four actually.

Mysterious new man-made gases pose threat to ozone layer

Dealing with the hole in the ozone layer has been one of the most successful international science projects

Scientists have identified four new man-made gases that are contributing to the depletion of the ozone layer.

Two of the gases are accumulating at a rate that is causing concern among researchers.

Worries over the growing ozone hole have seen the production of chlorofluorocarbon (CFC) gases restricted since the mid 1980s.

But the precise origin of these new, similar substances remains a mystery, say scientists.

Lying in the atmosphere, between 15 and 30km above the surface of the Earth, the ozone layer plays a critical role in blocking harmful UV rays, which cause cancers in humans and reproductive problems in animals.

Scientists from the British Antarctic Survey were the first to discover a huge “hole” in the ozone over Antarctica in 1985.

The evidence quickly pointed to CFC gases, which were invented in the 1920s, and were widely used in refrigeration and as aerosol propellants in products like hairsprays and deodorants.

Remarkably, global action was rapidly agreed to tackle CFCs and the Montreal Protocol to limit these substances came into being in 1987.

A total global ban on production came into force in 2010.

Now, researchers from the University of East Anglia have discovered evidence of four new gases that can destroy ozone and are getting into the atmosphere from as yet unidentified sources.

Three of the gases are CFCs and one is a hydrochlorofluorocarbon (HCFC), which can also damage ozone.

“Our research has shown four gases that were not around in the atmosphere at all until the 1960s which suggests they are man-made,” said lead researcher Dr Johannes Laube.

The scientists discovered the gases by analysing polar firn, perennial snow pack. Air extracted from this snow is a natural archive of what was in the atmosphere up to 100 years ago.

The researchers also looked at modern air samples, collected at remote Cape Grim in Tasmania.

They estimate that about 74,000 tonnes of these gases have been released into the atmosphere. Two of the gases are accumulating at significant rates.

“The identification of these four new gases is very worrying as they will contribute to the destruction of the ozone layer,” said Dr Laube.

“We don’t know where the new gases are being emitted from and this should be investigated. Possible sources include feedstock chemicals for insecticide production and solvents for cleaning electronic components.”

“What’s more, the three CFCs are being destroyed very slowly in the atmosphere – so even if emissions were to stop immediately, they will still be around for many decades to come,” he added.

Opinion:

…and they don’t know where they are coming from. Unbelievable.

Sounds to me like they’d better find out pretty fast.

Just another example of man’s incompetence.

 

 

Make you Fink on Friday

stop frackingWhy oil companies and governments should frack off!

There has been much said over this fracking issue, oil companies telling us that it’s safe, despite triggering earthquakes (which bought experts say is nothing related to the fracking), flammable gases cropping up in kitchens in such quantities that the kitchen tap can be ignited (once again, bought experts say this is not a result of fracking). The governments are rubbing their hands with glee at the prospect of endless oil, then lying through their teeth telling us that it is safe and we need it.

But a report yesterday tells the horrible truth.

California has run out of water. In Texas many areas are also out of water. Areas of these states have become desserts, farmers can’t irrigate crops.

Why?

Because they have wasted 97 billion gallons of water fracking.

The aquifers that keep the water running have dropped 300 metres, that is nothing short of disastrous.

When a river or a lake  is depleted, it is replenished after the next good rain. Not so with aquifers, they take years to replenish, some even centuries.

The aquifers are the delicate balance of nature between drought and plenty; you destroy them and you’ve got nothing left.

The truth about fracking is that it is to see how many ways you can f**k over Mother Nature.

Further, fracking involves injecting chemicals along with the vast quantities of water, Where does that contaminated water go? What chemicals are involved? How do these chemicals affect life?

Countries across the globe are getting into this bullshit, Cameron is fighting tooth and nail to get fracking going in Britain. The man is an IDIOT! As are all politicians who support fracking. New Zealand is doing it, New Zealand? It’s on a major tectonic plate line, are they going to trigger more earthquakes?

Who gives a shit, drill baby drill!
