Record-breaking #climatechange pushes world into ‘uncharted territory’

“Our children and grandchildren will look back on the climate deniers and ask how they could have sacrificed the planet for the sake of cheap fossil fuel energy, when the cost of inaction exceeds the cost of a transition to a low-carbon economy,”

Thin Ice

Climate science has been coming under increasing attack. Geologist Simon Lamb takes a look at what’s really happening with global warming by filming scientists at work in the Arctic, the Antarctic and around the world.

The result is a unique exploration of the science behind global warming, and an intimate portrait of a global community of researchers racing to understand our planet’s changing climate.

The Thin Ice project began over a cup of coffee at a climate change and governance conference in Wellington in 2006. Peter Barrett (Victoria University) suggested to Simon Lamb (then at Oxford University) that he make a film about the science of climate change with his friend David Sington (DOX Productions)

The idea was to let people see an insider’s view of the astonishing range of human activity and scientific work needed to understand the world’s changing climate. Viewers would then be able to decide individually and collectively how to deal with the issue.

Simon and David talked to researchers on four continents as they explained their work measuring changes in the atmosphere, oceans and ice sheets. They also discovered how scientists use computer models to understand the effects of those changes.

With the breakdown of methane hydrates in the Arctic seafloor, we may have already triggered runaway global warming.

Over 20 of the most terrifying images of 2016 - Arctic News

Methane, a greenhouse gas over 20 times more potent than carbon dioxide but a thousand times sparser in the atmosphere, has been rapidly increasing in concentration several-fold with human industrialisation: Graph of temperature variation, methane concentration and carbon dioxide concentration over the last 420,000 years, based on ice core data combined from both hemispheres. Showing a trend of rapid methane increase at the end of each glaciation, previously varying between about 400 and 800 parts per billion, currently around 2000 parts per billion.

This has been both driving and being driven by a ~50% loss in Arctic sea ice volume over the last decade, in a positive feedback cycle:

Combined with the loss of albedo (sunlight reflection) from snow and ice melting, increased water vapour from ocean evaporation further adding to the greenhouse effect, and eventual decrease in aerosol dimming as we give up on the remaining dirtiest and most expensive fossil fuel reserves, while solar output increases again from its recent minimum, this could add up to several degrees of warming:

Stacked bar chart of average temperature anomaly contributions from different feedback cycles, adding up to a rise of 10 degrees centigrade over pre-industrial averages.

Prof. Guy McPherson and Sam Carana have each in their own ways been advocating a dramatic view that such warming is likely to lead to near-term human extinction, but I think they vastly underestimate how tenacious some humans are, along with our ability to construct safe micro-climates for ourselves and grow food efficiently indoors without even using soil, while their prediction of all aerosol dimming stopping due to global industrial collapse forms a circular argument.

Billions of people being displaced by rising sea levels is a certainty and merely a matter of time, with enough ice on the currently-collapsing Greenland ice sheet for ~7m of sea level rise and enough on the relatively-stable Antarctic ice sheet for 58m (190ft), but the rapidity with which that occurs due to global actions to reduce emissions such as ending transcontinental trade in useless/fragile crap and large scale animal agriculture (ha, unlikely), along with how societies around the world handle mass migrations that make today's refugees look trivial and adapt their agricultural practices to shifting climatic zones, will have an influence on whether global population hits a steady plateau this century, or a few billion lives could be lost through famine and resulting worldwide civil wars, in a worst case eliminating us to less than one billion.

However, should that process ignite a global nuclear weapons exchange, then I could see where they are coming from on the threat of extinction, when combined with abandoned spent fuel rod pools evaporating and burning off even more radioactive material to the atmosphere.

You might find this post #NSFW if your occupation supports this insane global anti-economic system, but please enjoy the weekend.

#Shell's 1991 warning: #climate changing ‘at faster rate than at any time since end of ice age’

#climatechange #environment #science

"Shell had, in fact, known of the risks of climate change even earlier. A “confidential” company report written in 1986, also seen by the Guardian, noted the significant uncertainties in climate science at the time but warned of the possibility of “fast and dramatic” changes that “would impact on the human environment, future living standards and food supplies, and could have major social, economic, and political consequences”."

Isn't this basically a #crime against #humanity, acknowledging something but still fighting to stop any action to do anything?

Why we’re all everyday climate change deniers

After Donald #Trump won last month’s US presidential election, hot takes speedily declared it game over for the planet. But as #AlGore said at the weekend, “ #despair is just another form of #denial ”. About this, he is entirely right. Now is not the time to cry into your #graphs of melting #Arctic #sea ice. That only helps the people who #profit from delay on #ClimateChange.

Because #ClimateDenial isn’t just something other people do – bad people, sad people, #stupid people. It’s not just a niche hobby practised by the president-elect and weirder bits of the internet. It’s #mainstream.

Yes, there are those marginal, attention-seeking types who see a bit of light climate denial as banter. You know the type, that annoying guy your mate went to uni with, #Ukip candidates, embarrassing relatives.

Then there are the lonely ones who do it to make friends. There’s a strong social element to a lot of climate #scepticism – conversations in comment threads, #debates in #forums, offline meetups. There’s even climate sceptic fanfic if you know where to look.

There are “lukewarmer” types who admit climate change is happening but flail around looking for reasons why we shouldn’t bother to act. They might argue it won’t be that bad, or even that it’ll have positives – see, for instance, most oil executives.

Some have a genuine – albeit skewed – love of #science. The idea of busting a global warming myth carries the attractive illusion of heroic, outsider #genius. It’s not for nothing that a group of Australian sceptics style themselves on Galileo. There’s also a narrow empiricism to the idea that if you can see snow, global warming can’t be real. As Prof Joanna Haigh politely explained to Boris Johnson in response to one of his less-than-rigorous newspaper columns, it’s because scientists are so into #empiricism that they bother to look at a load of data – not just what you can see out the window at that moment.

But there is an even bigger group than any of the above: the rest of us. You probably agree climate change is happening, have maybe even bothered to cut down on how much meat you eat or bunged Greenpeace a quid or two when Russia locked up those Arctic activists. But most of the time you avoid looking global warming in the eye.

In many ways this everyday denial is understandable. Climate change is abstract. We only know about it through vast, complex, global and multi-generational networks of interdisciplinary, highly advanced science. It’s easy for it to drop out of our minds, even if we believe in it.

It’s also very scary. A friend who, once upon a time, was the greenest person I knew, hugs her infant son tight and tells me softly, slowly: “I just can’t think about climate change since I had him.” This feels entirely rational to me.

But it’s this rather prosaic climate denial that lets the Trumps of the world get away with their more extreme forms. It also lets less extreme politicians and businesses off the hook, helping keep climate change as a low-priority topic. At best it puts the issue to one side, and allows us to imagine that Chinese solar businesses, Elon Musk, Ivanka Trump or some other ethereal hero will save us. At worst, it skips the issue entirely.

Not everyone has the luxury of ignoring climate change. People are already feeling it as #droughts, #wildfires and #floods become more common. As temperatures creep ever higher, it’ll hit more and more of us, more and more obviously. Knock-on effects mean that, along with battling #fire, #water and #mud, #food will become more scarce. If you don’t spot climate change in the rising tides, you may well feel it in your stomach. This is already happening. Arguably, the way climate change affected #crops was a contributing factor in the Arab spring.

But here’s the hopeful bit. Climate change happens by degree, and every fraction of a degree celsius matters. Last month’s report saying we’re already 1.2C above pre-industrial levels is bad. But 1.2C is less risky than 1.5C, which is less risky than 2C.

This doesn’t let us off the hook. Indeed, the idea that 2C is somehow safe is itself a pernicious bit of climate denial. But there isn’t a single point or temperature at which everything is lost. There will always be something to fight for.

A few years ago I saw a climate scientist glumly sitting on a table in a seminar room, swinging his legs, quietly sketching out the vision of the future that kept him awake at night. His picture wasn’t an all-out dystopia where we’ve destroyed humanity. What scared him was a future where we do take action on climate change, but only some. A few rich people live in a comfortable bubble they’ve managed to insulate themselves in, and everyone else is left to battle the storms. Perhaps those lucky few notice the plight of the people they’ve left behind. Or perhaps they insulate themselves from that too.

That future is possible. It might even be probable. But it’s not inevitable. We can choose to see climate change, and we can choose to do this before it’s too late. So how can we escape the quagmire of denial? As it turns out, the first step isn’t that hard: just talk about it. To your #friends, #family, #colleagues – even to yourself. By talking about climate change, you’ll make it feel less scary. By talking about it, we’ll unlock solutions. And, crucially, it’s by talking about climate change that we’ll break the silence that allows it to go unnoticed and #ignored.
