Domestic Wood Burning Leads To “Very High Pollution Alert” For London
By Paul Homewood
From the BBC:
A "very high" air pollution warning has been issued for London for the first time under a new alert system.
Warnings are being issued at bus stops, roadside signs and Tube stations under the new system set up by London Mayor Sadiq Khan.
The rise has been attributed to cold, calm and settled weather, meaning winds are not dispersing local pollutants.
The mayor said "the shameful state of London’s toxic air" meant he had to trigger the alert.
"This is the highest level of alert and everyone – from the most vulnerable to the physically fit – may need to take precautions to protect themselves from the filthy air," he said.
A spike in pollution on Sunday was the highest level recorded since April 2011……
The last time pollution reached this level was early last month, according to pollution monitoring stations run by King’s College London.
However, a spike in pollution levels on Sunday "when there wasn’t much traffic on the road, was significant" Dr Fuller said.
In recent weeks several "high" alerts have been issued.
The current weather conditions, coupled with an "unusually high amount of domestic wood burning", has led to the highest pollution alert being issued.
I was too young to remember the great London smogs of the 1950s, but they led to Clean Air Acts, which amongst other things introduced smokeless zones where only certain types of coal could be burnt.
Unfortunately because of our obsession with “clean” renewable energy, we appear to be going backwards again.
