The air did seem fine this week so what was causing all the high readings?
Boris’s muppet alter-ego was out and about on Friday calming everybody down – Boris Johnson accused of ‘complacency’ over air quality
Although he is the man who can do most to tackle the situation and his comments are aggravating to say the least, I have to agree with his rank amateur unscientific commentary that “it seemed fine”.
I have a vague idea it had a lot to do with the poor people in Africa losing their topsoil as the global air circulation blows it over to us, in which case Boris would be powerless anyway. I shall look into it further.
