BMJ says global warming should be declared a public health emergency…

GLOBAL WARMING

Intro: The BMJ, a top medical journal, has been accused by critics of being ‘alarmist’ as it joins the green agenda…

A leading medical journal has warned that global warming is a ‘public health emergency’ that will cause thousands of deaths worldwide.

The BMJ claims that the ‘mayhem’ it will inflict on future generations will make deaths from the ebola outbreak ‘pale into insignificance’.

In an unusual move, the journal has set aside 11 pages of this week’s issue to warn doctors of the dire consequences of global warming – without any obvious relevance to medicine.

Critics described the article as ‘alarmist’ and ‘desperate’.

But in a separate commentary, the BMJ’s editor Dr Fiona Godlee defends the piece by saying doctors must understand the problem if they are to help tackle it. It is not the first time the publication – formerly known as the British Medical Journal – and its editor have spoken out on such a highly charged issue.

In July, it carried a piece calling for doctors to be allowed to help the terminally ill to die – prompting concern among medics.

In her most recent comments, Dr Godlee warns that seven million people die worldwide every year due to pollution and this will only increase if greenhouse gas emissions – which cause global warming – rise further. She points out that reducing these emissions by walking rather than using the car will have added benefits of reducing obesity, heart disease and diabetes.

And she calls on the World Health Organisation (WHO) to declare the issue a public health emergency – putting it on a par with the current ebola outbreak in West Africa which has claimed 3,000 lives since February.

‘Deaths from ebola infection, tragic and frightening though they are, will pale into insignificance when compared with the mayhem we can expect for our children and grandchildren if the world does nothing to check its carbon emissions.

‘And action is needed now,’ the article concludes.

Last year, experts from the Intergovernmental Panel on Climate Change (IPCC) warned that the average global temperature had risen by 0.5C in 50 years. They predicted that over the next century temperatures will increase by 3C causing a rise in sea levels, flooding, disease outbreaks and, as a result, mass migration of refugees. Politicians are striving to reach an international agreement by December next year on legally-binding targets to reduce greenhouse gas emissions. It would aim to limit global warming to just 2C, and will replace the Kyoto Protocol which came into effect in 2005.

However the last attempt at a deal, at the Copenhagen climate conference in 2009, ended in disaster, and many politicians are worried about a similar result this time.

Dr Benny Peiser, of the Global Warming Policy Forum, a think-tank founded by the climate-change denier and former Chancellor Lord Lawson, accused the BMJ report of being needlessly alarmist.

He said: ‘The World Health Organisation would become a global laughing stock if they were to follow the ridiculously over-the-top demands of a green alarmist editor. There is a real disconnect between what they are saying and the reality.’

He added that the article was ‘just desperate’, saying: ‘The smaller the chance of an international agreement, the more desperate they get.’

Rare beetle found in abundance…

MELOE BREVICOLLIS

A rare flightless beetle in Britain, thought to be close to extinction, has been found in abundance on a Hebridean island.

The short-necked oil beetle was thought to have disappeared completely until 2008, when scientific surveys uncovered two small populations in South Devon, and the Isle of Coll.

Researchers working for RSPB Scotland and charity Buglife have now found more than 150 of the threatened insects. This equates to a 400 per cent increase since the last count was made in 2010.

Scientists also identified two new sites on the island for the beetles, which rely on wild bees and their larvae to survive.

A spokesperson and natural recovery officer at RSPB Scotland, said:

… This was a beetle that was thought to be extinct for about 60 years… A small population was found in Devon and then, out of nowhere, about 20 individuals were discovered on Coll.

… To go back and find the species in such abundance now shows they are doing a lot better than we ever dreamt they could be.

The beetle – Latin name Meloe brevicollis – is named for the toxic oil secretions it produces when threatened.

A conservation officer at Buglife Scotland, said:

… The abundance of wildflowers in the machair and dunes of the island, combined with lots of warm, bare sand provide a near-perfect habitat for the solitary bees that the beetles depend on.

Pesticides require to be cut to save bees…

COLONY COLLAPSE DISORDER

Bees are an essential part of our life-cycle. Without them, flowers would not be pollinated and crops would fail. And as the world’s human population continues to grow, bee numbers in recent times have been falling, indicating that there is a big problem looming. Scientists are concerned.

Biologists and environmentalists have been puzzling about the cause for some time. Of particular concern is what has become known as colony collapse disorder, an affliction that has already led to the death of entire hives of bees during the winter months. The collapse of colonies is something which has been happening with frequent occurrence. The finger of suspicion is now pointing ever more firmly at insecticides and aggressive agricultural practices, especially those chemicals containing compounds known as neonicotinoids.

These are recently developed pesticides that have become widely used in agriculture because they are much less toxic to humans and other animals than the chemicals they replaced.

Evidence is mounting, though, that they are highly toxic to bees. A scientific study has found that hives that had similar levels of mite and parasite infestation, also thought to be a factor in colony collapse, were much more likely to die if the bees had also been exposed to neonicotinoid pesticides.

Empirically, several studies have now borne out this effect, with researchers edging closer in identifying the casual mechanism – that neonicotinoids are responsible for disrupting the immune and neurological systems of bees. This makes them less resistant to disease caused by parasites.

European and British regulators have already moved to restrict the use of neonicotinoids, but the case for a much tougher clampdown to reverse the loss of honey bees is gaining traction.
