By now those of ours with ears to listen know that we have a climate emergency.
I am growing very weary of articles like this one that say that unless we reduce emissions (sic) we will have a problem.
However,
I present this in honour of Prof.Peter Wadhams whose book A
Farewell to Ice comes out on 1 September.
Time to listen to the ice scientists about the Arctic death spiral
The
Arctic’s ice is disappearing. We must reduce emissions, fast, or
the human castastrophe predicted by ocean scientist Peter Wadhams
will become reality

Ice
scientists are mostly cheerful and pragmatic. Like many other
researchers coolly observing the rapid warming of the world, they
share a gallows humour and are cautious about entering the political
fray.
Not
Peter Wadhams. The former director of the Scott Polar Research
Institute and professor of ocean physics at Cambridge has spent his
scientific life researching the ice world, or the cryosphere, and in
just 30 years has seen unimaginable change.
When
in 1970 he joined the first of what would be more than 50 polar
expeditions, the Arctic sea ice covered around 8m sq km at its
September minimum. Today, it hovers at around 3.4m, and is declining
by 13% a decade. In 30 years Wadhams has seen the Arctic ice thin by
40%, the world change colour at its top and bottom and the ice
disappear in front of his eyes.
In
a new book, published just as July 2016 is confirmed by Nasa as the
hottest month ever recorded, this most experienced and rational
scientist states what so many other researchers privately fear but
cannot publicly say – that the Arctic is approaching a death spiral
which may see the entire remaining summer ice cover collapse in the
near future.

The
warming now being widely experienced worldwide is concentrated in the
polar regions and Wadhams says we will shortly have ice-free Arctic
Septembers, expanding to four or five months with no ice at all. The
inevitable result, he predicts, will be the release of huge plumes of
the powerful greenhouse gas methane, accelerating warming even
further.
He
and other polar experts have moved from being field researchers to
being climate change pioneers in the vanguard of the most rapid and
drastic change that has taken place on the planet in many thousands
of years. This is not just an interesting change happening in a
remote part of the world, he says, but a catastrophe for mankind.
“We
are taking away the beautiful world of Arctic Ocean sea ice which
once protected us from the impacts of climate extremes. We have
created an ocean where there was once an ice sheet. It is man’s
first major achievement in re-shaping the face of the planet,” he
writes.
And,
boy, are we seeing extremes. So far this year, the planet’s average
temperature has been 1.3C warmer than the late 19th century, and 2016
is virtually certain be the hottest year ever recorded.
Britain
and northern Europe may have had average temperatures, but 500
million people in the Middle East and north Africa, along with most
of south-east Asia, have experienced droughts and searingly hot days
and nights, which are only partly to do with the natural El NiƱo
phenomenon. Meanwhile, China, India and the US have seen some of
their longest heatwaves and worst floods in decades, and nearly 100
million people will need food aid in the coming months because of
disrupted rainfall patterns.
Mitribah
in Kuwait has reported a world record 54C, India and Iran have both
recorded their highest ever temperatures, and deadly heatwaves have
struck China, the US, Indonesia and New Zealand. We are perilously
close to the 1.5C limit of warming that all countries signed up to in
Paris last year and on track for a 3C-4C increase which would make
much of the world uninhabitable.
Because
Wadhams says what other scientists will not, he has been widely
slandered, attacked and vilified by denialists and politicians who
have advised caution or non-action. But now he returns their fire,
exhorting people to counter what he calls “the sewage flow of lies
and deceit” emitted by the deniers. Above all, he says, people who
study climate change should speak up and be prepared to risk the
blighting of their careers and absence of honours.
But
he joins other climate researchers to cross lines that the public may
still find unacceptable. He wants global action to find new ways to
remove carbon from the atmosphere, and is not afraid of nuclear power
– both of which answers can be swallowed – but he also argues for
a colossal, global research programme in geo- engineering.
This
is the deliberate attempt to reduce warming by the planetary-scale
manipulation of weather patterns, oceans, currents, soils and
atmosphere to decrease the amount of greenhouses gases.
Spraying
sun-reflecting chemicals into the atmosphere, mimicking volcanoes,
blocking sunlight and fertilising the oceans with iron filings
attracts people who think that technology has all the answers, but it
should strike fear into most of the world, which has not been
responsible for warming and which has no reason to trust politicians’
or scientists’ further meddling with planetary forces.
How
to proceed safely in a warming world without disastrous unintended
consequences? The need for truly urgent action is undeniable, but by
the time answers have been found to the massive questions of science,
engineering and governance that Wadhams agrees need to be solved
before geo-engineering on a planetary scale can go ahead, it will be
far too late.
Climate
change has been caused by ignorance and stupidity and cannot be
solved by endorsing more of the same with geo-engineering. The only
answer is reducing greenhouse emissions. Fast.
