Don’t you just hate it when teenagers insist that they know the answers to all the world’s problems, but we oldies are too stupid to see that they are right?
They
say things like this: ‘The scientific evidence is that if we have not taken
dramatic action within the next decade, we could face irreversible damage to
the natural world and the collapse of our societies.’ (‘Irreversible damage?’
‘Collapse of our societies’? C’mon …)
Or
this: ‘If we do not change course by 2020, we risk missing the point where we
can avoid runaway climate change.’ (‘Runaway climate change’? What’s that, for
goodness sake?)
Typical
teenage over-simplification. A failure to understand the complexities and
uncertainties of climate science. And a millennial vision of an apocalypse that
has more in common with cultish fanaticism than rational discourse among
sensible adults.
Ah.
Sorry. I may have misled you. Those quotes aren’t, in fact, from the
16-year-old Swedish climate activist Greta Thunberg but from the sage and
living saint Sir David Attenborough, who’ll be marking his ninety-third
birthday in a couple of weeks’ time, and the secretary-general of the United
Nations, António Guterres, who will be seventy next week. Sprightly though they
both undoubtedly are, neither could reasonably be labelled a teenager.
(By
the way, if you haven’t yet watched Attenborough’s recent TV documentary Climate Change – The Facts, please do.
You can find it by clicking here. But I should warn you: it is truly
terrifying.)
My
point is simply this: yes, Greta Thunberg is only a teenager, but her warnings
about the urgency of the climate change crisis are precisely mirrored by what
scientists have been saying for ages. Her youth, her pigtails, and her
Asperger’s, which results in her speaking with unusual clarity and force, mean
that she can capture the headlines and the front-page photos in a way that not
even David Attenborough can match.
Take
her much-misunderstood demand that governments should commit to zero carbon
emissions within the next twenty years. In a speech to MPs this week, she said:
‘Our emissions have to stop if we are to stay below 1.5-2 degrees Celsius of
warming. The “lowering of emissions” is of course necessary, but it is only the
beginning of a fast process that must lead to a stop within a couple of decades
or less.’
How
absurd, say her critics, by whom I mean those who will not or cannot
understand. How can anyone seriously believe that within two decades, the whole
of humanity can simply stop using fossil fuels? Planes, cars, ships, power
generation, industry?
After
all, according to a report this week in the Financial Times, greenhouse gas emissions from planes more than doubled between 1990
and 2016, and if Heathrow gets its third runway, its capacity will rise from
480,000 to 740,000 flights per year by the mid-2020s. But
perhaps Greta Thunberg’s critics and the cynics should try listening more
carefully to what she actually said, because her next sentence was ‘By “stop”,
I mean net zero.’
But
of course that’s not what we are doing. Instead of planting more trees to act
as the earth’s lungs, we’re chopping them down. According to a new analysis by
the World Resources Institute, demand for beef (produced from cattle that are
fed on soya, which is grown on land which has been deforested), palm oil
(produced from trees grown on vast plantations where once tropical forests
stood), and chocolate (produced from cocoa grown on land once occupied by
forests in, for example, Ghana and Ivory Coast) means forests are still
disappearing at a terrifying rate.
It’s
nearly eight years now since I reported from the Amazon, at a time when the
then Brazilian government was grappling with the dilemma of how to protect the
environment while continuing to expand the economy. (My TV report from July
2011 is here.) But now, after the election of the populist,
anti-environmentalist president Jair Bolsonaro, there’s no longer any doubt:
agri-business interests have won, and the environmentalists have lost.
It’s
hard, but not impossible, to find heroes in this dismal tale of impending doom.
Greta Thunberg is one of them, for having forced the issue into the political arena.
So too are the thousands of Extinction Rebellion protesters, who with immense
good humour, discipline and imagination, have risked arrest to draw attention
to the seriousness of the crisis.
I
also think a round of applause is due to the former mayor of New York, Michael Bloomberg, who over the past two years has contributed a total of $10 million
to the United Nations Climate Change secretariat to cover the gap left by the
Trump administration’s withdrawal from the 2016 Paris climate change agreement.
Yes,
I know his personal wealth is estimated at $60 billion, so he can certainly
afford it. Even so, I applaud the gesture. On its own, of course, it won’t save
the planet. But it might just help.
