[Our common home is under attack! Our dearest comrade Planet Earth, who gives us life, is slowly shedding us. At the ends of the Earth, the Ice Caps are melting because humans cannot stop their addiction to cheap oil. In Africa, western oil corporations exploit weak regulations to sell toxic fuel to our fellow beings. Capitalism is at war with our common home! Their blind obsession with hording wealth and power will destroy all life on this planet. The strength of the Earth if far more than ours. Earth has faced far worse and lived to bring new life again! In essence, we only destroy ourselves. We must realize that the struggle for Communism is the struggle for our planet! Upon this planet we are all related. From the grass we walk upon, to the flora and fauna that nourish us, to our fellow humans, we are all related. -El Condor]
Second lowest minimum for
Arctic ice cover in 2016 reached the second lowest minimum on record, tied with 2007.
The sea-ice extent on 10 September stood at 4.14 million sq km, some way short of the 3.39 million sq km record low in 2012.
Arctic sea-ice cover grows each autumn and winter, and shrinks each spring and summer.
It has long been regarded as a sensitive indicator of change to the Earth’s climatic system.
The ice extent has been tracked by the US National Snow and Ice Data Center (NSIDC) in Boulder, Colorado, using satellite measurements.
However, the centre cautioned that the figures were preliminary, adding that changing winds could still push the ice extent lower.
Ted Scambos, NSIDC lead scientist, commented: “It really suggests that in the next few years, with more typical warmer conditions, we will see some very dramatic further losses.”
This year’s minimum is seen as something of a surprise as scientists believed that the low atmospheric pressure and cloudy skies in June and July had slowed down the melt.
“It’s pretty remarkable that this year’s sea-ice minimum extent ended up the second lowest, after how the melt progressed in June and July,” said Walt Meier, a sea ice scientist with Nasa’s Goddard Space Flight Center.
“June and July are usually key months for melt because that’s when you have 24 hours a day of sunlight – and this year we lost melt momentum during those two months.”
Record global land and sea surface temperatures in 2015 that continued to shatter records well into 2016 had led many to believe that the Arctic melt would reach a new low mark this year. But some scientists, including experts from Reading University in the UK, argued that their analysis of melt ponds on ice floes indicated that 2016 would not beat 2012.
While tying for the second lowest minimum in the satellite era, this year’s figure is in fact well above the 2012 melt, which saw the ice cover fall to 3.41 million sq km (1.32 million sq mi) – 50% lower than the 1979-2000 average.
Fuel ‘too dirty’ for Europe sold to Africa
Swiss firms have been criticised in a report for their links to the African trade in diesel with toxin levels that are illegal in Europe.
Campaign group Public Eye says retailers are exploiting weak regulatory standards.
Vitol, Trafigura, Addax & Oryx and Lynx Energy have been named because they are shareholders of the fuel retailers.
Trafigura and Vitol say the report is misconceived and retailers work within legal limits enforced in the countries.
Three of the distribution companies mentioned in the report have responded by saying that they meet the regulatory requirements of the market and have no vested interest in keeping sulphur levels higher than they need to be.
Although this is within the limits set by national governments, the sulphur contained in the fumes from the diesel fuel could increase respiratory illnesses like asthma and bronchitis in affected countries, health experts say.
Why are regulations so lax?
The picture is changing but there are still several African countries which allow diesel to have a sulphur content of more than 2,000 parts per million (ppm), with some allowing more than 5,000ppm, whereas the European standard is less than 10ppm.
Rob de Jong from the UN Environment Programme (Unep) told the BBC that there was a lack of awareness among some policy makers about the significance of the sulphur content.
For a long time countries relied on colonial-era standards, which have only been revised in recent years.
Another issue is that in the countries where there are refineries, these are unable, for technical reasons, to reduce the sulphur levels to the standard acceptable in Europe. This means that the regulatory standard is kept at the level that the refineries can operate at.
Some governments are also worried that cleaner diesel would be more expensive, therefore pushing up the price of transport.
But Mr De Jong argued that the difference was minimal and oil price fluctuations were much more significant in determining the diesel price.
What’s so bad about sulphur?
The sulphur particles emitted by a diesel engine are considered to be a major contributor to air pollution, which the World Health Organization (WHO) ranks as one of the top global health risks.
It is associated with heart disease, lung cancer and respiratory problems. The WHO says that pollution is particularly bad in low and middle income countries.
Reducing the sulphur content in diesel would go some way to reducing the risk that air pollution poses.
What’s being done about it?
Unep is at the forefront of trying to persuade governments to tighten up the sulphur content regulations and is gradually making progress.
In 2015, the East African Community introduced new regulations for Kenya, Uganda, Rwanda, Burundi and Tanzania. Diesel cannot now have more than 50ppm in those countries.
It is clear that the situation has improved since 2005.
Unep’s Jane Akumu is currently working with the West African regional grouping Ecowas and its Southern African counterpart Sadc to try and change the regulations there.
She told the BBC that she was optimistic that governments would bring down the legal sulphur limits as the arguments in favour are compelling.
