Nature rounds up reaction from researchers around the world to US President Donald Trump's decision t
o pull the United States out of the Paris climate agreement.
Jane
Lubchenco, marine ecologist at Oregon State University in Corvallis and
former administrator of the US National Oceanic and Atmospheric
Administration:
Where to start? President
Trump’s decision to withdraw from the Paris Agreement shows a blatant
disregard for the wishes of most Americans and business leaders, an
irresponsible and callous dismissal of the health, safety and economic
well-being of Americans, a moral emptiness in ignoring impacts to the
poorest people in the US and around the world, and gross ignorance about
overwhelming scientific evidence. Far from “protecting America” as the
president stated, withdrawing from Paris will make America more
vulnerable and diminish its world leadership. It is terrifying that the
individual who should be leading the rest of the world is so arrogant
and irresponsible.
Our collective future and
that of much of the rest of life on Earth depends in part on confronting
climate change and ocean acidification. Doing so requires global
collective action. It’s hard to imagine anyone consciously choosing to
leave a legacy of impoverishment, economic disruption, increasingly
bizarre weather, health impacts ranging from heat strokes to spread of
diseases, rising sea levels and flooding — but that is just what the
president has done. Moreover, the new path and the president’s proposed
budget would forego significant economic opportunities.
Fortunately,
mayors, governors, faith leaders, scientists and business executives
understand what is at risk, respect the scientific evidence, and see the
powerful economic potential and moral imperative in shifting to
renewable energy, preparing to adapt to changes already under way, and
investing in science and monitoring to guide future decisions. There is
strong economic momentum to continue these actions, but they would have
been accelerated and more effective with strong action and forceful
leadership from the president. Alas, he has chosen instead to stick his
head in the sand.
Jean-Pascal van Ypersele,
climate scientist at the Catholic University of Louvain in
Louvain-la-Neuve, Belgium, and former vice-chair of the
Intergovernmental Panel on Climate Change (IPCC):
President
Trump's decision to introduce a request to leave the Paris agreement in
2020 is regrettable. It negates both the results of (1) serious
scientific analyses (many made by US scientists) about the urgency to
address the climate change problem; and (2) the rigorous assessment made
by the IPCC about the technical and socio-economic aspects of response
options, including their significant co-benefits in other areas like air
quality, energy security, health or job creation.
President
Trump's speech attempting to justify his decision was an amazing
concentrate of some of the worst climate confusers' and fossil
lobbyists' arguments.
The United States has
played a very important role over the years to foster and nurture
quality scientific research about the causes and processes of climate
change, the potential risks and the response options. It is a shame that
this leadership by the US is temporarily lost. Others in Europe, Asia
and emerging economies will most likely compensate for this loss,
transforming a difficulty into an opportunity.
Almost
150 countries, representing close to 85% of greenhouse-gas emissions,
have now ratified the Paris agreement. Removing the US contribution from
this total still leaves almost two-thirds of the emissions covered by
the remaining countries, which have confirmed their plans to honour the
agreement. This means that the transition to a low-carbon economy, now
seen as an opportunity by many, will continue unabated, with or without
the US.
Susanne Dröge, climate-policy researcher at the German Institute for International and Security Affairs in Berlin:
The
US pull-out is bad news for the international climate process. The
United Nations negotiations need to focus on implementation. This will
become more difficult, also because it is unclear how Trump wants to
renegotiate the agreement. Political attention is absorbed due to the US
move, attention that is needed for much more important issues such as
bringing climate action forward.
Thomas
Stocker, former co-chair of climate science for the IPCC, and climate
and environmental physicist at the University of Bern, Switzerland:
Trump’s
decision to ignore scientific facts of climate disruption and the high
risks of climate-change impacts is irresponsible not only towards his
own people but to all people and life on this planet. The US
administration prefers old technology over innovation and
transformation. It is rejecting the enormous benefits and returns that
leadership in the next industrial revolution — decarbonization — has to
offer.
The United States is the second-biggest
emitter of carbon dioxide worldwide (and has contributed, with Europe,
52% of the share of cumulative carbon emissions since
industrialization). It is withdrawing from its historical responsibility
to reduce greenhouse-gas emissions and lead the way forward. Given the
continuous commitment of most countries to reduce emissions, and the
firm leadership of Europe, China and Russia in shaping the
transformation towards a decarbonized economy, the United States runs
the risk of being left behind and missing one of the greatest economic
opportunities of our time.
Susan Lozier, oceanographer at Duke University in Durham, North Carolina:
Trump’s
decision is as short-sighted as it is disheartening. The oceans already
hold about 35% of the carbon dioxide that has been released to the
atmosphere since the Industrial Revolution. Nothing good for the ocean
and the life it contains comes from this storage. Whether you simply
admire marine life or count on it for your livelihood, this decision
shouldn’t sit well. An already fragile ocean is further imperilled.
Kevin Anderson, deputy director of the Tyndall Centre for Climate Change Research in Manchester, UK:
Beneath
the veil of the low-carbon rhetoric of the Paris agreement, there is no
evidence of a mitigation agenda even approaching the scale of our
international obligations. Trump’s ostensibly reckless decision can be
used either as a further excuse for continued apathy or as a catalyst
for transforming our comfortable rhetoric into meaningful and timely
action. In that regard, Trump’s ignorant blunderings can inadvertently
be a force for good. Channelled positively, it could yet oblige the rest
of us to forego our increasing reliance on speculative technologies and
incremental carbon prices and begin to shape a mitigation agenda that
is fit for purpose.
We need to take Trump at
face value. If he is successful in returning the US to a coal-based
economy (and that looks unlikely), then the European Union needs to
borrow his ‘protectionist’ cloak and put in place carbon standards for
imported goods.
Finally, let’s keep Trump in
context. US states and cities have considerable devolved powers — and
many of their leaders continue to favour climate science.
Joeri Rogelj, energy researcher at the International Institute for Applied Systems Analysis in Laxenburg, Austria:
The
US withdrawing from the Paris agreement is damaging for international
collaborative efforts to limit climate change, but will likely be most
damaging to the US economy itself. The US has decided to sideline
itself, internationally, diplomatically and morally — not to prepare
itself for the future, but to gaze into the past for a few more years.
Many other major economies, including China and the European Union, have
indicated their strong commitment to implementing the climate
agreement. This signal will spur innovation and business development in
these regions. However, the US government refuses to give US businesses
such a clear sense of direction and is disregarding the most robust
scientific evidence by doing so. By setting research, innovation and
business priorities based on misleading short-term political goals, the
US will miss the boat and might become a laggard in the global
technology and innovation landscape.
The
climate issue is a global and a cumulative problem that was not solved
in one go with the Paris agreement, but requires incremental updates and
adjustments of climate action. To halt climate change, global carbon
dioxide emissions need to be capped and annual emissions need to be
brought to zero. One country failing on its commitments thus implies
that deeper emissions cuts are required in other regions or later in the
future. This makes the problem harder and less equitable to solve.
Oliver Geden, visiting research fellow at the Institute for Science, Innovation and Society, University of Oxford, UK:
The United States gave up climate leadership on the day of Trump's inauguration. In March, Trump announced his
rollback of Obama-era climate regulations.
So it’s been clear for some time that the US federal government is not
going to act on climate change in the foreseeable future. Withdrawing
from the Paris agreement is just another step, although a highly
symbolic one.
For now, it seems that this step
reunites the rest of the world, but only on the symbolic level. It is
quite easy for a government to declare that it will stick to the Paris
agreement. But in a regime of bottom-up climate policy that still aims
to achieve top-down temperature targets, other governments would need to
step up and declare that they increase their mitigation pledges — and
act accordingly. That's obviously the harder thing to do.
Katharine Hayhoe, director of the Climate Science Center at Texas Tech University in Lubbock:
The
biggest loser from the decision could be the United States itself. Why?
Because although the Paris agreement is a climate treaty, a triumph for
evidence-based decision-making, it’s also much more: a trade agreement,
an investment blueprint and a strong incentive for innovation in the
energy and the economy of the future.
Earlier this week, India broke its own record for the lowest bids for electricity from solar power. Last month,
Ernst & Young listed its most attractive markets for renewables: the United States came third, behind China and India. And earlier this year, China announced a
US$360-billion investment in clean energy
to create 13 million new jobs. The US announcement shows that it will
be doing its best to turn back the clock, while the rest of the world
accelerates into the future.
It’s true that
federal policy is only one piece of the pie, and not even the biggest
one. Cities, states and private industry have arguably played an even
more important role in shaping US technological innovation, energy mix
and carbon emissions over the past ten years, even under proactive
federal climate policy. But Trump’s announcement sends a strong message
that the US would rather be one of only two nations in the world that is
not interested in preventing “dangerous anthropogenic interference with
the climate system”. That other nation? War-torn Syria. (Note that
Nicaragua is also opting out of the agreement — but in that case it’s
because it wants to do more, not less.)
Atte Korhola, climate-policy and environmental-change researcher at the University of Helsinki, Finland:
The
US withdrawal from the Paris climate agreement is very disappointing
and unfavourable for the United States and the rest of the world. Many
climate scientists consider the Paris agreement insufficient for
limiting warming to 2 °C, so the task will be all the harder now.
However, international climate agreements have not been very effective
so far in reducing emissions, so there is still hope that the United
States will proceed on other fronts, such as through bilateral
agreements, clean-tech development and investing in new ‘negative
emissions’ technologies.
But the plans by the
Trump administration to cut more than 30% from the Environmental
Protection Agency’s budget and about 70% of the funding for
renewable-energy research and development unfortunately don’t point in
this direction. The situation in all respects is quite depressing. The
only hope is that the US states, cities and companies will continue
their effective work to cut emissions.
Benjamin Santer, climate scientist at Lawrence Livermore National Laboratory in California:
In Shakespeare's
Julius Caesar,
Brutus said these famous lines: "There is a tide in the affairs of men.
Which, taken at the flood, leads on to fortune; Omitted, all the voyage
of their life is bound in shallows and in miseries."
Today, the United States pulled out of
the Paris climate agreement
and missed the rising tide. Far from "Making America Great Again", this
decision condemns the United States to becoming one of the 'has-beens'
of history. We will become increasingly irrelevant to the rest of the
world. They are going forward; we are going backward.
Hans Joachim Schellnhuber, director of the Potsdam Institute for Climate Impact Research in Potsdam, Germany:
It
will not substantially hamper global climate progress if the US really
quits the Paris agreement, but it will hurt the American economy and
society alike.
China
and Europe have become world leaders on the path towards green
development already and will strengthen their position if the US slips
back at the national level. Innovative states such as California, the
world's sixth-largest economy, will keep going for climate action,
however. The Washington people around Trump hide in the trenches of the
past instead of building the future. They fail to recognize that the
climate wars are over, while the race for sustainable prosperity is on.
David Victor, climate-policy expert at the University of California, San Diego:
The
odds of other countries renegotiating Paris are low to zero. The whole
structure of the Paris agreement is to allow countries to set their own
commitments. So there is nobody to negotiate with if a country needs to
adjust. This claim that the problem with Paris is that the deal wasn’t
struck properly is a disingenuous argument that is not informed by how
Paris actually works, nor by any reality about how the world actually
crafts big complex deals.
Glen Peters, climate-policy expert at the Center for International Climate and Environmental Research in Oslo:
It
seems that Trump and his advisers have completely misconceived what the
Paris agreement is. All his reasons for pulling out were basically the
concessions that forged the path to the creation of the Paris agreement.
Paris is the agreement that Trump desires!
The
genius of Paris is to allow countries to put forward emission pledges
that they feel they can meet (Nationally Determined Contributions). The
US pledge was put forward by the US, alone. Countries are already
enacting their emissions pledges, and — as could be expected by the
design of the Paris agreement — most countries show signs of exceeding
their conservative emissions pledges. China looks like it may peak its
emissions a decade earlier than pledged. India has slowed down on coal
consumption and sped up on solar deployment. Even the US has made great
strides in the past decade, and was poised to make more.
The
irony is that Paris is working, because it is designed to be flexible
to the national circumstances that Trump himself champions!
Myles Allen, climate scientist at the University of Oxford, UK:
The
Paris agreement is far from perfect, and one of its problems, as we are
seeing now, is the lack of any real penalty for pulling out. Talk of
trade sanctions is pure hyperbole and the last thing the world needs
right now. But perhaps it is time to think about a simple product label:
“Made in and sourced from regions that support the Paris climate
agreement.” With California and Oregon insisting they will abide by the
terms of the Paris agreement anyway, we could then have an interesting
discussion about whether and how this could be stuck on Californian
orange juice — or computers containing Intel chips.
Painful
though it may be for the agreement’s supporters, acknowledging that it
isn’t perfect must also be part of the response to this proposal to
renegotiate the US terms of participation. Some, no doubt, will see this
as just a distraction tactic. Others would argue that even to begin to
negotiate would be to deliver Trump an ill-deserved political “win”. But
thinking beyond 2020, we will eventually need to work out how to make
the agreement both more effective and more acceptable to nations,
companies and individuals that own substantial fossil-fuel reserves — or
the US won’t be the last to leave.
Benjamin Sanderson, climate modeller at the National Center for Atmospheric Research in Boulder, Colorado:
Today's
announcement that the US will depart from the Paris agreement is
unfortunate, but it is no time for fatalism. From this point forward,
there are now large uncertainties in global mitigation efforts over the
coming years. The long-term evolution of the climate hinges on what
other countries, and agents both within and outside of the US, do in
response to the US departure from the agreement.
A
complete failure of the agreement at this point, with business-as-usual
growth for another decade, would almost certainly commit the planet to
significantly more warming than the Paris goals, and the human
consequences of this would be catastrophic. However, some major
remaining signatories have expressed a commitment to increasing
mitigation goals, and within the US, many states, cities and some of the
country's largest companies are committed to mitigation irrespective of
the US participation in the agreement.
Decisions
made today are made in the context of confident projections of future
warming with continued emissions, but clearly there is more to do to
better characterize the human and economic consequences of delaying
action on climate change and how to frame these issues in the context of
other concerns. The role of the scientific community is more important
than ever, both to continue to provide the best possible research to
inform decisions, and to communicate any risks associated with further
emissions in a publicly accessible fashion.
