Is the planet warming up faster?
This is not a word-for-word transcript
Neil
Hello This is 6 Minute English from BBC Learning English I’m Neil
Sam
And I’m Sam
Neil
“No one is too small to make a difference” Do you know who said that, Sam?
Sam
Wasn’t it climate change activist, Greta Thunberg?
Neil
That’s right She went on to say this in her message to world leaders: “I don’t
want you to be hopeful I want you to act as if your house is on fire Because it is”
Sam
Her speech reflected the feelings of many young people around the world who
think that not enough action is being taken on climate change
Neil
And they may be right, judging by the record-breaking temperatures that hit
Canada and the north-west of the United States in July this year
Sam
Yes, Greta Thunberg’s plea to ‘act like your house is on fire’ became a reality for
residents of the small town of Lytton, Canada which burned to the ground in a
shocking wildfire – a fire that is burning strongly and out of control
Neil
So, was the Lytton wildfire yet another climate change wake-up call? A wake-up
call is the expression used to describe a shocking event that should make people
realise that action is needed to change something
Sam
Well, maybe not, according to some climatologists who, worryingly, say that
what happened in Lytton should not even have been possible So in this
programme we’ll be asking if scientists have dangerously misunderstood the
realities of climate change
Neil
But first it’s time for my quiz question and it’s about that extreme weather in
Canada It broke records when the temperature in Lytton hit an all-time high on
1st July - but just how hot did it get? Was it:
a) 39 point 6 degrees?,
b) 49 point 6 degrees? or
c) 59 point 6 degrees Celsius?
Sam
All those temperature look really high, especially for snowy Canada I’ll say a) 39
point 6 degree C
Neil
OK, Sam, we’ll find out the answer later on Seeing your hometown burn to the
ground is bad enough, but perhaps even worst was the fact that the wildfires
were so unexpected
Sam
According to weather pattern modelling done by a team of Oxford University
researchers, such extreme heat was impossible - in theory, at least
Neil
The research team was led by climatologist, Geert Jan van Oldenborgh Here he
is in conversation with BBC World Service programme, Science in Action:
Roland Pease
This is a wake-up call beyond the wake up calls that we’ve had before
Geert Jan van Oldenborgh
Yes, and it’s a very big shock in the sense that we thought we knew how
heatwaves react to global warming and within which boundaries they’re
increasing (of course they’re increasing in temperature) but it’s a gradual process
we thought and then you get this thing and it’s not gradual at all – it’s a huge
jump!
Sam
Professor Van Oldenborgh had been studying the impact of global warming on
heatwaves - short periods of time when the weather is much hotter than usual
Neil
Along with other climatologists, he thought that climate change was gradual –
changing or happening slowly, over a long period of time
Sam
But the Canadian heatwaves caused him to think again Instead of being gradual
the temperatures saw a jump, or a sudden increase, of five degrees And it’s this
sudden jump that’s got Professor Van Oldenborgh and his team worried
Neil
By collecting data from all over the world climatologists try to predict changes in
the pattern of global warming
Sam
But, as Geert Jan van Oldenborgh told BBC World Service’s, Science in Action, the
heatwave in Lytton didn’t fit these predictions at all:
Geert Jan van Oldenborgh
Everything looked like a nice regular gradual trend like we were used to up to
last year and then you suddenly break all your records by four or five degrees, I
mean, this is something that’s no supposed to happen and it has really shaken
our confidence in how well we understand the effect of climate change on
heatwaves
Neil
Despite all his research, Professor Van Oldenborgh is still unable to explain such
extreme and sudden changes in the climate – and this, he says, has shaken his
confidence - made him doubt something that he was certain was true
Sam
And it’s this lack of understanding worrying researchers because, as the story of
the town of Lytton shows, the effects of climate change may be even worse than
expected
Neil
Maybe it’s time we all took notice of Greta Thunberg’s wake-up call to take
action on climate change
Sam
Especially if even cold, northern countries like Canada, or Britain for that matter,
can experience such extreme changes Speaking of which, Neil, what was the
answer to your quiz question?
Neil
Ah yes, in my quiz question I asked you exactly how high the temperature
reached in the Canadian town of Lytton What did you say, Sam?
Sam
I thought it was a) 39 point 6 degrees Celsius Was I right?
Neil
Well, you were close but in fact it got even hotter, actually reaching 49 point 6
degrees Celsius – the highest temperature ever recorded in Canada by at least 5
degrees!
Sam
Phew! That’s hot Well, we’d better recap the vocabulary from this programme
because we might be hearing these words a lot more in the future! Let’s start
with a wildfire which is an out-of-control fire that is burning the countryside
Neil
A wake-up call is an event which should make people realise that action needs to
be taken to change a situation
Sam
A heatwave is a period of days or weeks when the weather is much hotter than
usual
Neil
A jump is a sudden increase…
Sam
…whereas gradual means happening slowly, over a long time
Neil
And finally, if something shakes your confidence, it makes you doubt something
that you thought was true
Sam
That’s it for our look at one of the hottest years on record
Neil
Bye for now!
Sam
Bye!
