Seriously, don’t miss this report. It’s mercifully short, and its reference scenario is all too likely. Which is not at all good news. And while you’re at the Breakthrough site, take a look as well at Climate Emergency: What is safe, the 1.5º target, and is the end nigh?, wherein Breakthrough’s David Spratt explains the 1.5C target to an Australian Extinction Rebellion group.
David Spratt, the Australian hawk behind Climate Code Red, and now the Australian Breakthrough Institute, is very good on the science. And on what he calls the “emergency mode.” Not that going into “emergency mode” answer all questions about what must be done, or how to do it. But set that aside for the moment. If what you want is a summary of the science in which there are no punches pulled, watch this presentation, which David gave to a Australian Extinction Rebellion crew in May of 2019
Back in March, I debated Rupert Reed at the Center for European Studies at Berkeley. Rupert is a British Green politician and philosopher (a Wittgenstein expert, actually) who has recently emerged as a spokesman for the Extinction Rebellion. The debate is not uninteresting. In fact, it got quite rather testy at several points, as for example when I felt compelled to defend the IPCC against Rupert’s rather apocalyptic take on radicalism. Here’s the video. . .
It’s two years now since Paris, and time for another dose of Kevin Anderson, straight-shooter extraordinaire. You can get it by watching this talk, given at Anderson’s home base at the University of Manchester. The talk begins at time-code 11:00 and runs until about 42:20. There’s a lot more to say, but Anderson fits a lot into those 31 minutes. My only quibble is with his explanation of why the political elites behind the Paris Agreement were so eager to celebrate it, which I find to be painfully thin. But the mainline of talk is great, as far as it goes, and that’s pretty far, actually. Here’s a sample slide:
If you’re in the mood for a half hour of of me, along in my room talking into a microphone, and you’d like to see a sketch of the book I have under development (it’s called Fair Enough?), you might want to take a look at this video, which was (is?) my contribution to an online climate conference organized by John Foran at UC Santa Barbara’s Environmental Humanities Initiative.
This “nearly carbon-neutral” conference is entirely online. It’s a format that has its charms, not the least of which is that it could be international without involving air-travel. But I must confess that I missed the usual drinks party. You know, actually meeting people and talking. In the flesh.
There are two things to keep in mind if you would know the climate future. The first is that, as scientific statesman John Holdren likes to say, it will come to us as a mixture of mitigation, adaptation, and suffering. The second is that the suffering will be disproportionately visited upon the poor and the innocent.
Where once there was constant recourse to “this storm/drought/surge is consistent with global warming,” we’re now increasingly likely to hear “this storm/ drought/surge would not have happened without global warming.”
Hold these thoughts when considering the massive tome just issued by the IPCC’s Working Group II. (The much briefer Summary for Policymakers, or SPM, is here). Working Group II (or “WG2” for short) is the part of the International Panel on Climate Change – the largest, most sustained, and arguably most important peer-reviewed scientific enterprise in history – which is focused on understanding climate-change related “impacts, adaptation, and vulnerability.” Its report, released on Monday, comes halfway though the year-long roll-out of the three volume set that together make up the IPCC’s “Firth Assessment Report.”
Volume I is focused on climate science in itself – the “physical science basis” of the crisis. It was released in September and can be found here. Volume III, due out later this month, is focused on mitigation – that is, on what the nations of the world can do to slow and then, hopefully, stop greenhouse gas emissions.
Since the release of WG1’s report in late 2013 has perhaps faded from memory, it’s useful to recall it and to pause to appreciate that WG1 did its job well. In fact, it’s not too much to say that the first volume, coming at a time when climate denialism was already sagging, gave us a fine marker of its now accelerating decline. It did so by stepping past the contrived denialist shitstorm that was “Climategate” with a decisive summary and restatement of our increasingly firm – and increasingly grim – understandings.
The Credit Suisse Global Wealth Report is a useful item. In a world where income statistics are generally the best we can do, it leverages its customized Swiss-banker research machine to estimate the real stats, the ones about wealth itself. Wealth as in ownership. I say “estimate” because, well, the really rich don’t particularly like being studied. Anyway, Global Wealth Report 2013 contains some stats I’ve been looking for. Here’s they are, from page 10:
“Our estimates for mid-2013 indicate that once debts have been subtracted, an adult requires just USD 4,000 in assets to be in the wealthiest half of world citizens. However, a person needs at least USD 75,000 to be a member of the top 10% of global wealth holders, and USD 753,000 to belong to the top 1%. Taken together, the bottom half of the global population own less than 1% of total wealth. In sharp contrast, the richest 10% hold 86% of the world’s wealth, and the top 1% alone account for 46% of global assets.”
Here’s a picture that, among other things, shows you where there rich actually live:
I’ve come here today to argue that whatever policy mix we cook up, it has to be one that leads to the complete elimination of emissions to the atmosphere from the combustion of fossil fuels in the second half of the century . . . We don’t need to get to zero tomorrow. Not even in 2050, although we should be a long way down the track by then. But sometime in the second half of the century we will need to arrive there.
How are we going to do so? With a policy mix designed to price carbon, phase out coal, increase the ambition of the current pledges, get beyond policy wobbles on renewables, and phase-out fossil-fuel subsides.
The IPCC’s new assessment report hasn’t even been released, but the denialist fog machine is already running hard. If you’re tired of it — and, frankly, if you’re tired of the smoothly-leveled understatement that we usually get from the IPCC — take a look at Is Climate Change Already Dangerous?, a new report by David Spratt of Australia’s Climate Code Red.
I’ll not summarize this report; there’s no point because it’s already a summary, one which sticks extremely close to the original scientific literature. But I will say that its focus is the Arctic, which as you may have noticed is getting a lot of nervous attention these days. And this for the very good reason that it’s melting before our eyes! Spratt’s paper is excellent on this subject – it lays out the basics of the situation and gives you the citations you need to drill deeper. Assuming you’re up to it. The message, after all, is that we’ve already crossed the thin red line into the days of “dangerous climate change.”
What’s happening here? Here’s a nice overview from Professor Peter Wadhams, of Cambridge University and the Catlin Arctic Survey. The author of a recent paper called Arctic ice cover, ice thickness and tipping points and a leading authority on the polar regions, Wadhams says:
“I have been predicting [the collapse of sea ice in summer months] for many years. The main cause is simply global warming: as the climate has warmed there has been less ice growth during the winter and more ice melt during the summer… in the end the summer melt overtook the winter growth such that the entire ice sheet melts or breaks up during the summer months. This collapse, I predicted would occur in 2015–16 at which time the summer Arctic (August to September) would become ice-free. The final collapse towards that state is now happening and will probably be completed by those dates. As the sea ice retreats in summer the ocean warms up (to +7ºC in 2011) and this warms the seabed too. The continental shelves of the Arctic are composed of offshore permafrost, frozen sediment left over from the last ice age. As the water warms, the permafrost melts and releases huge quantities of trapped methane, a very powerful greenhouse gas so this will give a big boost to global warming.” (Vidal, 2012)
