Emmylee at my birthday BBQ

Emmylee at my birthday BBQ

It’s been a quiet week after my bursts of energy around my birthday. Speaking of which, today is Emmylee’s.

*ties knot in finger to remember to phone her*

Give Emms my camera and I get an 8gb SD chip full of selfies…

Anyway, today she’s reached the ripe old age of eight.

BIG news, American waistlines have grown an inch in the last decade.

More news, to fight cancer… roll in the kitty litter.

It appears that the bacteria, Toxoplasma gondii, we get from our feline buddies and is carried by 60% of the population is a cancer hunting/destroying bacteria. What can I say, get closer to your pussy! Cheaper than chemotherapy.

Sad news…

The reason we need Marina da Silva for presidenta! (See last wee’ks CTWW)

The dams are dry, sorry too late

In recent months Brazil has undergone a severe water shortage, particularly in the state of São Paulo. A report in the news this morning is rather disturbing. It appears that deforestation of the Amazon basin has reached a threshhold The vegetation of the Amazon basin let moisture rise and so produce the clouds that moved across the country and fell as rain. Apparently, there is not enough vegetation left to make suffcient moisture to form the necessary clouds. Brazil’s inaction, or insufficient action, has caused their own demise. Had the country been more prudent earlier, we wouldn’t have these drought problems. Another example of man’s inability to husband the planet effectively.

This week it was reported that deforestation in Brazil increased for the first time in the last few years, despite a major illegal logging band being dismantled.

Now let’s move along.

This week’s CTWW is about CFCs

This week, let’s deal with any ozone-depleting chemicals in our lives. Here are some steps to take:

  • Check labels and avoid any solvents, cleaning supplies, foams, etc. which contain CFCs (in addition to the common names mentioned above, they might be found on the label as methane, ethane, Trichlorotrifluoroethane).
  • Check storage areas for old aerosol cans, fire extinguishers, or air conditioning units and dispose of them properly (call your hazardous waste disposal department for information on the best way to dispose of them).

There’s a lot more, check the banner above for the rest.

greencheckMy life is CFC Free.

My refrigerator is only a couple of years old and CFC free.

I don’t have any old stuff like aerosols, fire extinguishers, etc in use that might contain CFCs; and I don’t use air conditioning.

However, I do still have my two old fridges that are bound to have CFCs. I haven’t thrown them out as I use them in the carport for storage cupboards.

“In Brazil, a pilot project was launched to remedy this problem. Working within the framework of the Swiss Climate Protection Initiative, the Swiss foundation SENS International launched a project to recycle old refrigerators and other cooling appliances in a manner compliant with Swiss standards.
It is not enough to merely replace old refrigerators with more energy-efficient and environmentally friendly ones. The old appliances also need to be recycled in a manner that ensures the complete extraction and destruction of CFCs. However, this requires a certain degree of know-how, specific equipment and facilities as well as new legislation. Until fairly recently, these factors were missing.”Source No date given.

The problem is the recycling plant is in São Paulo, 460km away. I’ll have to look into this further and see if there are any facilities here in Rio.

Another source tells me there is a comprehensive recycling programm for old fridges but doesn’t sy where, have to look further.

Meanwhile, it’s back to bed… 3am writing CTWW, I am seriously in need of therapy.

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.

The Halley Research Station in Antarctica, where the hole in the ozone layer was first discovered

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.

Grim discovery

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.
