Now updated it seems! But, as the TV people sometimes say, a good time to
check your barometer.
Out of interest, what is the significance of the 1013hPa line? Is that
figure a generally accepted delineation between high and low pressure or
is
it just a facet of this particular forecaster?

1013.25 hPA is average sea-level pressure.

In the good old days of mercury- in- glass barometers, Torrecelli
found the atmosphere supported a 76 cm long column of mercury.
A nice round figure which converts to a not so round 1013.25 mb.
How they decided 76 cm of mercury was an average sea level pressure I
do not know.
Was it the average pressure in Rome in a year around 1643? What about
adjusting to sea level?
Were they that clever?

No pressure, eh -
Does that mean that some ecogreenie teacher is going to press a little
red button and destroy young climate realists who refuse to be
brainwashed by their "educators"?

Yep saw that disgraceful AGW video made by that Rat Bag Richard
Curtis. I've never forgiven him for the nasty hurtful joke he wrote at
Margaret Beckett's expense on the Vicar of Dibley. The poor woman was
humiliated nationally, If I ever bump into the prat I'll let him know.
I hate so called left political comedian as they are invariably
personally cruel and always not the remotest bit funny and think all
they have to do is mention the names Thatcher and Archer and the BBC
type fall about in righteous self hysterics. Yet not one of them
criticised that cruel Beckett so called gag. That's the mind set
we're dealing with.
