When
science speaks of what world governments and their peoples once
thought of as an impossibility and, the vast majority of Australian
politicians still refuse to admit the extent of the perilous
situation situation we find ourselves in, then as a society we have
entered a dark place.

‘Hopeless
and broken’: why the world’s top climate scientists are in
despair

Hundreds
of the world’s leading climate scientists expect global
temperatures to rise to at least 2.5C (4.5F) above preindustrial
levels this century, blasting past internationally agreed targets and
causing catastrophic consequences for humanity and the planet, an
exclusive Guardian survey has revealed.
Almost
80% of the respondents, all from the authoritative Intergovernmental
Panel on Climate Change (IPCC), foresee at least 2.5C of global
heating, while almost half anticipate at least 3C (5.4F). Only 6%
thought the internationally agreed 1.5C (2.7F) limit would be met.
Many
of the scientists envisage a “semi-dystopian” future, with
famines, conflicts and mass migration, driven by heatwaves,
wildfires, floods and storms of an intensity and frequency far beyond
those that have already struck.
Numerous
experts said they had been left feeling hopeless, infuriated and scared by the failure of governments to act despite the clear scientific
evidence provided.
“I
think we are headed for major societal disruption within the next
five years,” said Gretta Pecl, at the University of Tasmania.
“[Authorities] will be overwhelmed by extreme event after extreme
event, food production will be disrupted. I could not feel greater
despair over the future.”
But
many said the climate fight must continue, however high global
temperature rose, because every fraction of a degree avoided would
reduce human suffering.
Peter
Cox, at the University of Exeter, UK, said: “Climate change will
not suddenly become dangerous at 1.5C – it already is. And it will
not be ‘game over’ if we pass 2C, which we might well do.”
The
Guardian approached every contactable lead author or review editor of
IPCC reports since 2018. Almost half replied, 380 of 843. The IPCC’s
reports are the gold standard assessments of climate change, approved
by all governments and produced by experts in physical and social
sciences. The results show that many of the most knowledgeable people
on the planet expect climate havoc to unfold in the coming decades.
The
climate crisis is already causing profounddamage to lives and livelihoods across the world, with only 1.2C
(2.16F) of global heating on average over the past four years. Jesse
Keenan, at Tulane University in the US, said: “This is just the
beginning: buckle up.”
Nathalie
Hilmi, at the Monaco Scientific Centre, who expects a rise of 3C,
agreed: “We cannot stay below 1.5C.”
The
experts said massive preparations to protect people from the worst of
the coming climate disasters were now critical. Leticia Cotrim da
Cunha, at the State University of Rio de Janeiro, said: “I am
extremely worried about the costs in human lives.”
The
1.5C target was chosen to prevent the worst of the climate crisis and
has been seen as an importantguiding star for international negotiations. Current climate
policies mean the world is ontrack for about 2.7C, and the Guardian survey shows few IPCC
experts expect the world to deliver the huge action required to
reduce that.
Younger
scientists were more pessimistic, with 52% of respondents under 50
expecting a rise of at least 3C, compared with 38% of those over 50.
Female scientists were also more downbeat than male scientists, with
49% thinking global temperature would rise at least 3C, compared with
38%. There was little difference between scientists from different
continents.
Dipak
Dasgupta, at the Energy and Resources Institute in New Delhi, said:
“If the world, unbelievably wealthy as it is, stands by and does
little to address the plight of the poor, we will all lose
eventually.”
The
experts were clear on why the world is failing to tackle the climate
crisis. A lack of political will was cited by almost three-quarters
of the respondents, while 60% also blamed vested corporate interests,
such as the fossil fuel industry.
Many
also mentioned inequality and a failure of the rich world to help the
poor, who suffer most from climate impacts. “I expect a
semi-dystopian future with substantial pain and suffering for the
people of the global south,” said a South African scientist, who
chose not to be named. “The world’s response to date is
reprehensible – we live in an age of fools.”
About
a quarter of the IPCC experts who responded thought global
temperature rise would be kept to 2C or below but even they tempered
their hopes.
“I
am convinced that we have all the solutions needed for a 1.5C path
and that we will implement them in the coming 20 years,” said Henry
Neufeldt, at the UN’s Copenhagen Climate Centre. “But I fear that
our actions might come too late and we cross one or severaltipping points.”
Lisa
Schipper, at University of Bonn in Germany, said: “My only source
of hope is the fact that, as an educator, I can see the next
generation being so smart and understanding the politics.”
