summers in the UK uh are getting super
hot. We are on track right now uh
according to the UK Met Office for
probably the hottest summer uh on
record. We're we're we're tracking as as
hot as it's ever been. And uh this is a
uh this is something cities uh around
the world are having to deal with.
hotter summers, uh longer duration heat
waves, more extreme temperatures, the
highs getting higher, the length of
these hot spells lasting longer. Uh but
you know, cities that have transported
have have have dealt with this um in in
in very different ways and and the
experience of of those commutes is is is
quite a bit different in different
places.
>> Yeah. I mean, the one of the issues with
the London Underground is some of the
older infrastructure. It's like quite
literally creaking infrastructure. So,
what options do cities like London have
in in trying to adapt if they can't
install air conditioning?
>> Yeah, and that's a really really great
point. If you look at uh the subway
commute in uh Tokyo, in in Beijing, you
know, they've they've got, you know, air
conditioned uh uh uh subway carriages.
They've got air conditioned platforms.
They're able to uh blow in this sort of
refrigerated air. It's not quite air
conditioning, but it it manages to bring
down the temperature a little bit. And
then, you know, in Beijing, they have uh
uh uh uh subway carriages that are even
colder for for for business people that
have to wear jackets and suits or or or
or tights and uh you know, more formal
business attire every day. Um but a lot
of those systems um uh as you as you as
you hinted at were built you know in the
last uh several decades not a century
ago like London's underground or you
know a century ago like parts of the the
Paris metro and we see these uh these
subway systems in these cities with the
really old uh and in many cases deep
narrow tunnels that were built a century
ago really Victorian era uh architecture
in these places really struggling to add
air conditioning and to keep those uh
systems cool and that's increasing as it
gets hot uh and gets hotter outside. But
you know also these uh subway systems
themselves uh add heat uh to to the
tunnel. surprising amount of that heat
comes from just, you know, putting the
brakes on uh these uh subway cars
themselves.
