James
Hansen, father of climate change awareness, calls Paris talks 'a
fraud'
The
former Nasa scientist criticizes the talks, intended to reach a new
global deal on cutting carbon emissions beyond 2020, as ‘no action,
just promises’

Mere
mention of the Paris climate talks is enough to make James Hansen
grumpy. The former Nasa scientist, considered the father of global
awareness of climate change, is a soft-spoken, almost diffident
Iowan. But when he talks about the gathering of nearly 200 nations,
his demeanor changes.
“It’s
a fraud really, a fake,” he says, rubbing his head. “It’s just
bullshit for them to say: ‘We’ll have a 2C warming target and
then try to do a little better every five years.’ It’s just
worthless words. There is no action, just promises. As long as fossil
fuels appear to be the cheapest fuels out there, they will be
continued to be burned.”
The
talks, intended to reach a new global deal on cutting carbon
emissions beyond 2020, have spent much time and energy on two major
issues: whether the world should aim to contain the temperature rise
to 1.5C or 2C above preindustrial levels, and how much funding should
be doled out by wealthy countries to developing nations that risk
being swamped by rising seas and bashed by escalating extreme weather
events.
But,
according to Hansen, the international jamboree is pointless unless
greenhouse gas emissions aren’t taxed across the board. He argues
that only this will force down emissions quickly enough to avoid the
worst ravages of climate change.
Hansen,
74, has just returned from Paris where he again called for a price to
be placed on each tonne of carbon from major emitters (he’s
suggested a “fee” – because “taxes scare people off” – of
$15 a tonne that would rise $10 a year and bring in $600bn in the US
alone). There aren’t many takers, even among “big green” as
Hansen labels environment groups.
Hansen
has been a nagging yet respected voice on climate change since he
shot to prominence in the summer of 1988. The Nasa scientists, who
had been analyzing changes in the Earth’s climate since the 1970s,
told a congressional committee that something called the “greenhouse
effect” where heat-trapped gases are released into the atmosphere
was causing global warming with a 99% certainty.
A
New York Times report of the 1988 testimony includes the radical
suggestion that there should be a “sharp reduction in the burning
of coal, oil and other fossil fuels that release carbon dioxide”, a
plea familiar to those who have watched politicians who have traipsed
up to the lectern or interviewer’s microphone in Paris over the
past two weeks.
After
that, things started to get a little difficult for Hansen. He claims
the White House altered subsequent testimony, given in 1989, and that
Nasa appointed a media overseer who vetted what he said to the press.
They held practice press conferences where any suggestion that fossil
fuels be reduced was considered political and unscientific, and
therefore should not be uttered.
“Scientists
are trained to be objective,” Hansen says. “I don’t think we
should be prevented for talking about the the implications of
science.” He retired from Nasa in 2013. “That was a source of
friction. I held on longer than I wanted, by a year or two. I was in
my 70s, it was time for someone else to take over. Now I feel a lot
better.”
From
being possibly America’s most celebrated scientist, Hansen is now
probably its most prominent climate activist. He’s been arrested
several times in protests outside the White House over mining and the
controversial Keystone pipeline extension.
He
is also an adjunct professor at Columbia University. When he’s in
New York, he lives near the campus, surrounded by books piled on
groaning shelves. Hansen’s not slowing down – he’s involved in
a climate lobbying group and still undertakes the sort of scientific
endeavor which helps maintain his gravitas.
One
particular paper, released in July, painted a particularly bleak
future for just about anyone living near the coast. Hansen and 16
colleagues found that Earth’s huge ice sheets, such as those found
in Greenland, are melting faster than expected, meaning that even the
2C warming limit is “highly dangerous”.
The
sea level could soon be up to five meters higher than it is today by
the latter part of this century, unless greenhouse gases aren’t
radically slashed, the paper states. This would inundate many of the
world’s cities, including London, New York, Miami and Shanghai.
“More
than half of the world’s cities of the world are at risk,” Hansen
says. “If you talk to glaciologists privately they will tell you
they are very concerned we are locking in much more significant sea
level rises than the ice sheet models are telling us.
“The
economic cost of a business as usual approach to emissions is
incalculable. It will become questionable whether global governance
will break down. You’re talking about hundreds of million of
climate refugees from places such as Pakistan and China. We just
can’t let that happen. Civilization was set up and developed with a
stable, constant coastline.”
The
paper has yet to be fully peer reviewed and some of Hansen’s
colleagues, including his protege at Nasa, Gavin Schmidt, have voiced
their doubts whether sea level rise will be quite this bad, with the
IPCC projecting up to a meter by 2100.
Brickbats
are thrown in a bipartisan way. Hansen feels Obama, who has made
climate change a legacy issue in his final year in office, has
botched the opportunity to tackle the issue.
“We
all foolishly had such high hopes for Obama, to articulate things, to
be like Roosevelt and have fireside chats to explain to the public
why we need to have a rising fee on carbon in order to move to clean
energy,” he says. “But he’s not particularly good at that. He
didn’t make it a priority and now it’s too late for him.”
Hansen
is just as scathing of leading Republicans who have embraced climate
science denialism to the chagrin of some party elders.
Leading
presidential candidates Donald Trump, Marco Rubio and Ben Carson have
all derided evidence that the world is warming due to human activity
while Ted Cruz, another contender, has taken time out from his
campaign to to sit on an inquiry into climate science that has heard
testimony from a rightwing radio host who has no scientific
background.
“It’s
all embarrassing really,” Hansen says. “After a while you realise
as a scientist that politicians don’t act rationally.
“Many
of the conservatives know climate change is not a hoax. But those
running for president are hamstrung by the fact they think they can’t
get the nomination if they say this is an issue. They wouldn’t get
money from the fossil fuel industry.”
There
is a positive note to end on, however. Global emissions have somewhat
stalled and Hansen believes China, the world’s largest emitter,
will now step up to provide the leadership lacking from the US. A
submerged Fifth Avenue and deadly heatwaves aren’t an
inevitability.
“I
think we will get there because China is rational,” Hansen says.
“Their leaders are mostly trained in engineering and such things,
they don’t deny climate change and they have a huge incentive,
which is air pollution. It’s so bad in their cities they need to
move to clean energies. They realise it’s not a hoax. But they will
need co-operation.”
