1. The planetary emergency gets substantially worse. And still ‘nobody’ cares.

   ‘Low sea ice extent continues in both poles

   January 5, 2017

   Sea ice in the Arctic and the Antarctic set record low extents every day in December, continuing the pattern that began in November. Warm atmospheric conditions persisted over the Arctic Ocean, notably in the far northern Atlantic and the northern Bering Sea. Air temperatures near the Antarctic sea ice edge were near average. For the year 2016, sea ice extent in both polar regions was at levels well below what is typical of the past several decades.’

2. Funny how only TVNZ never covered this public health issue that affects many of us today????

   Time for TVNZ to be investigated here as this has been covered by every other media.

   Study finds living near a busy road could cause dementia

   Living near a busy road could cause dementia.

   Exposure to traffic fumes and noise was found to raise the risk by up to 12 per cent, according to a major study in UK medical journal, The Lancet.

   It might even explain one in nine cases of dementia among patients living within 50m of major routes. The findings – from research tracking seven million people over a decade – suggest that environmental factors play a role in a disease that affects 850,000 Britons.

   Dementia had been seen as largely genetic but factors such as smoking, obesity and lack of exercise are increasingly under suspicion. And the new study, published last night in the Lancet medical journal, highlights air pollution and noise.

   Costing the NHS £26 billion ($46b) a year, dementia has overtaken heart disease as the biggest cause of death in England and Wales. Drugs can control the symptoms but there is still no effective treatment to slow or cure the disease.

   The Canadian research reveals the closer someone lives to a major road – and the longer they live there – the higher their risk of developing dementia.

   Dr Hong Chen, who led the University of Toronto study, said: ‘With our widespread exposure to traffic and the greater tendency for people to live in cities these days, this has serious health implications.’

   The team plotted the addresses of 6.6million adults aged between 20 and 85 living in the province of Ontario, and then tracked them for 11 years between 2001 and 2012. Those living within 50 metres of a major route – a main urban road or a motorway – were 7 per cent more likely to develop dementia than those who lived 300 metres away. This increased to 12 per cent for those living at the same address for all 11 years.

   Those who lived between 50 metres and 100 metres away had a 4 per cent increased risk, and those between 101 metres and 200 metres had a 2 per cent increased risk. Those living more than 200 metres from a major road had no increased risk, the scientists found.

   The results have major implications for Britain which has a population density five to ten times that of Ontario. The UK is also notoriously bad at controlling air pollution, with 37 cities persistently breaching legal limits set by the EU.

   Scientists suspect that nitrogen dioxide and the sooty particles generated by diesel engines interfere with the blood-brain barrier, the crucial membrane which stops harmful chemicals entering brain cells.

   They also think pollution may provoke inflammation in the brain, a problem which may trigger dementia. Other studies have found that persistent noise is linked to cognitive impairment.

   NHS watchdog NICE last month warned air pollution now contributes toward 25,000 deaths a year in England – almost 5 per cent of the total.

   Professor Tom Dening, director of the centre for old age and dementia at the University of Nottingham, said: ‘It is certainly plausible that air pollution from motor exhaust fumes may contribute to brain pathology that over time may increase the risk of dementia. This evidence will add to the unease of people who live in areas of high traffic concentration.

   ‘It is unlikely that Ontario has the worst air quality in the world, so the risks might be even greater in cities that are habitually wrapped in smog.’

   Environmental lawyer Alan Andrews of law firm ClientEarth, which is spearheading a legal case against the Government over air pollution, said: ‘This study is the latest to show a worrying link between air pollution and a devastating condition that affects hundreds of thousands of older people in the UK.

   ‘The Government needs to urgently introduce a range of ambitious measures to tackle pollution from diesel vehicles.’
