How climate scepticism turned into something more dangerous

Doubts about the science are being replaced by doubts about the motives of scientists and their political supporters. Once this kind of cynicism takes hold, is there any hope for the truth? By David Runciman

Last month Donald Trump announced his intention to withdraw the United States from the Paris climate accord. For his supporters, it provided evidence, at last, that the president is a man of his word. He may not have kept many campaign promises, but he kept this one. For his numerous critics it is just another sign of how little Trump cares about evidence of any kind. His decision to junk the Paris accord confirms Trump as the poster politician for the “post-truth” age.

But this is not just about Trump. The motley array of candidates who ran for the Republican presidential nomination was divided on many things, but not on climate change. None of them was willing to take the issue seriously. In a bitterly contentious election, it was a rare instance of unanimity. The consensus that climate is a non-subject was shared by all the candidates who appeared in the first major Republican debate in August 2015 – Jeb Bush, Scott Walker, Ben Carson, Ted Cruz, Marco Rubio, Rand Paul, Chris Christie, John Kasich, Mike Huckabee and Trump. Republican voters were offered 10 shades of denialism.

'Limitless applications': the 'magic powder' that could prevent future crises

Metal organic frameworks could solve everything from water shortages to rotting food. Now Australian scientists have found a way to commercialise it

It sounds like a distant dystopian crisis: a world where global food and water supply chains buckle under the strain of overpopulation and climate change, before being contaminated by weapons of mass destruction unleashed in a desperate fight for access to what little is left.

While the crisis may not be as unrealistic or far away as it seems, scientists are already coming up with potential solutions. One is the curiously named metal organic frameworks (MOFs), a powder of nano-engineered crystals with an apparently endless variety of uses.

France to ban sales of petrol and diesel cars by 2040

Move by Emmanuel Macron’s government comes a day after Volvo said it would only make fully electric or hybrid cars from 2019

France will end sales of petrol and diesel vehicles by 2040 as part of an ambitious plan to meet its targets under the Paris climate accord, Emmanuel Macron’s government has announced.

The announcement comes a day after Volvo said it would only make fully electric or hybrid cars from 2019 onwards, a decision hailed as the beginning of the end for the internal combustion engine’s dominance of motor transport after more than a century.

Why it's D-day for Donald Trump at the G20 in Hamburg | Michael H Fuchs

The president’s foreign policy credentials are about to face their sternest test yet as global opinion of the US plummets

Michael H Fuchs is a former US deputy assistant secretary of state

Donald Trump will travel to Germany this week to participate in his first G20summit. While most multilateral meetings are full of lofty rhetoric about global cooperation – and feature slightly awkward group photos that resemble a high school yearbook – the G20 meeting appears uniquely engineered to challenge Trump’s foreign policy instincts. Trump may face his most difficult in-person foreign policy test in Hamburg.

Presidential travel is often filled with pomp and circumstance, but such trips can also reveal a president’s true colors. Saudi Arabia – a repressive dictatorship – was Trump’s choice for his first stop in office. While there, Trump made time for meetings with some of the world’s less savory leaders, but had no time for meeting with the members of civil society systematically repressed in the Middle East. In Europe afterwards, he removed language affirming America’s commitment to defend Nato allies from his speech, sending shudders through the continent.

What Nottinghamshire’s bee-eaters tell us about conservation and big business

Exotic migrants to the UK have set up home in a quarry owned by a sand mining company – an industry that is destroying wildlife habitats worldwide

At the end of June some exotic migrants flew into the country who have been enthusiastically welcomed by the Daily Mail. Following a hazardous journey from southern Europe a gang of seven bee-eaters have set up home in a desolate quarry in Nottinghamshire.

But while their presence is an inspiring example of the benefits of free movement, their choice of a quarry owned by Mexican minerals multinational Cemex raises some difficult questions about the relationship conservation has with big business.

Naomi Klein: how power profits from disaster

After a crisis, private contractors move in and suck up funding for work done badly, if at all – then those billions get cut from government budgets. Like Grenfell Tower, Hurricane Katrina revealed a disdain for the poor. By Naomi Klein

There have been times in my reporting from disaster zones when I have had the unsettling feeling that I was seeing not just a crisis in the here and now, but getting a glimpse of the future – a preview of where the road we are all on is headed, unless we somehow grab the wheel and swerve. When I listen to Donald Trump speak, with his obvious relish in creating an atmosphere of chaos and destabilisation, I often think: I’ve seen this before, in those strange moments when portals seemed to open up into our collective future.

One of those moments arrived in New Orleans after Hurricane Katrina, as I watched hordes of private military contractors descend on the flooded city to find ways to profit from the disaster, even as thousands of the city’s residents, abandoned by their government, were treated like dangerous criminals just for trying to survive.

How Obama's climate change legacy is weakened by US investment in dirty fuel

Exclusive: an agency inside the Obama administration poured billions into fossil fuel projects that will lead to global carbon emissions on a damaging scale

President Barack Obama has staked his legacy on the environment, positioning his administration as the most progressive on climate change in US history.

However, an obscure agency within his own administration has quietly spoiled his record by helping fund a steady outpouring of new overseas fossil fuel emissions – effectively erasing gains expected from his headline clean power plan or fuel efficiency standards.

The last thing we should be doing is providing corporate welfare to some of the biggest polluters on the planet

We thought the situation was going to improve under Obama. We had no idea it was going to be far worse

Obama's complicated legacy on climate change - video

Trump and the GOP may be trying to kneecap climate research | Dana Nuccitelli

While Trump claims to be open-minded on climate, there are ominous signs that Republicans will try to slash climate research

Last week, Donald Trump’s space policy advisor Bob Walker made headlines by suggesting that the incoming administration might slash Nasa’s climate and earth science research to focus the agency on deep space exploration. This caused great concern in the scientific community, because Nasa does some of the best climate research in the world, and its Earth science program does much more. Walker suggested the earth science research could be shifted to other agencies, but climate scientist Michael Mann explained what would result:

It’s difficult enough for us to build and maintain the platforms that are necessary for measuring how the oceans are changing, how the atmosphere is changing, with the infrastructure that we have when we total up the contributions from all of the agencies ... we [could] lose forever the possibility of the continuous records that we need so that we can monitor this planet.

The fact that they have reported temperature that they said was the highest temperatures...in history...it turned out that they were only 39% sure of that figure. Well that’s a press release, not a scientific kind of statement. I’m interested in scientific integrity. I’m interested not in scientific analysis that goes to a politically correct outcome.

I don’t think it’s the vast majority of climatologists who believe that [global warming is happening and man-made] ... among climatologists there is still a debate about the causes of the global warming. And so I think that debate is healthy, and I am entirely concerned about the fact that some of the climatologists that do not buy into the orthodoxy are being prevented from even having their works published.

the number of skeptical qualified scientists has been growing steadily; I would guess it is about 40% now.

97% of working climate scientists say the temperature is rising, and human activity is a significant contributing factor.

Frightened by Donald Trump? You don’t know the half of it | George Monbiot

Many of his staffers are from an opaque corporate misinformation network. We must understand this if we are to have any hope of fighting back against them

Yes, Donald Trump’s politics are incoherent. But those who surround him know just what they want, and his lack of clarity enhances their power. To understand what is coming, we need to understand who they are. I know all too well, because I have spent the past 15 years fighting them.
