Popcorn catastrophe


Ken Ward observes that when climate activists cry catastrophe! and then list benefits like green jobs and reduced oil imports to be gained if we take preventative measures, [it] is odd and confusing behaviour, like running into a crowded movie theater and shouting "Fire! -- and don't forget to buy popcorn on the way out, with all the unexpected traffic, it's on sale!".

This reminds me of one of my disappointments with Australia's current government. Despite heads rolling, it has succeeded in passing the Clean Energy Legislation that puts a price on carbon, compensates low income households and small businesses, and invests in renewables. In the weeks leading up to implementation, it ran an ad campaign about it. What did they say?

Did they mention that this legislation is a response to the catastrophe of climate disruption, like "We know the cinema is on fire, here comes the fire brigade!"

Did they say, "We're on the job, making Australia a safer place for future generations."

No, they ran ads of soothing domesticity that said, "You'll get some money. Aren't we nice?"

That's it. Nothing else. Indeed, they didn't even mention the legislation!

This is like addressing the crowd in the cinema and not mentioning the fire that has started in the projection room, saying instead, "There's a street parade outside they are throwing coins to the crowd."

Little wonder that Australians are disappointed and confused by their government.

Nevertheless, muddled as they are, the Government is better than the Opposition who have promised to undo the Clean Energy Legislation. That's like disbanding the Fire Brigade. I guess that their messaging is consistent. Given that they don't fully acknowledge climate disruption, it's like saying, "There is no fire so we don't need a Fire Brigade."

Eventually, all countries will get onto war footing to fight climate disruption. In the meantime, as individuals we can match our words and actions to the magnitude of the problem and call a spade a spade, as the very excellent James Hansen does in this Washington Post article today.

UPDATE: Researchers note that altruism and personal gain tend to cancel each other out. Appeals to self-interest can backfire and accidentally encourage people to behave selfishly in other areas.

Bucket brigade - better than watching the house burn


Climate change deniers who patrol the second defensive line, the moat, agree that the planet is warming but they dispute that the cause is human greenhouse gas emissions (GHGs).  They say that there is not enough evidence to support this view and governments should not act until there is more evidence. This is just a delay tactic, and fortunately it has been ignored by nearly every government on the planet many of which have spent the past two decades enacting policies and plans that have started their transition to low-carbon economies. Examples of recent action are shown on the Transformation tab above.

Richard Muller is the latest scientist to support the view that human generated GHGs are the main forcing element behind the current warming. He argues, as many others have, that when you compare the few vaguely plausible explanations for changing climate - greenhouse forcing, solar forcing, aerosol forcing, big changes in albedo - one fits the data MUCH better than any of the others. That one is greenhouse gases.

It's like a race between the contenders, and GHG has lapped the field twice to come in well ahead of the pack. This is not enough for some people, they want GHGs to win the race at the speed of light before they'll accept the evidence. 

Paul Fisher put it like this:
If a house is burning down and I suggest a bucket brigade, slow and cumbersome as it might be, there is no value in pointing out the chances of it working are slim unless you have something better to use in replacement. Simply allowing the house to burn down is not a useful solution. It is, at least, time to stop pretending the house isn't full of bad wiring that should be replaced, even if we can't agree there are already sparks and the walls are smoking.

UPDATE: David Potter points out that the bucket brigade metaphor is similar to Roosevelt's words in WWII:
Suppose my neighbor's home catches fire, and I have a length of garden hose....
 USA President Franklin Delano Roosevelt, 11 March 1941, on lending resources to the UK

The castle walls are breached


The defensive walls of the Denier citadel were breached today by Richard Muller's announcement that he is no longer sceptical about climate science.
Call me a converted skeptic. Three years ago I identified problems in previous climate studies that, in my mind, threw doubt on the very existence of global warming. Last year, following an intensive research effort involving a dozen scientists, I concluded that global warming was real and that the prior estimates of the rate of warming were correct. I’m now going a step further: Humans are almost entirely the cause.

This particular 'road to Damascus' moment carries weight because Muller was outspoken in his criticism of aspects of the temperature record and he attracted significant funding from the Koch brothers (fossil fuel billionaires who fund climate change deniers). Arch-denier Anthony Watts took the extreme step of cancelling his vacation and imposing a three-day silence on his blog in readiness for the BIG announcement. Perhaps he was preparing his next line of defence, or gathering forces for a new defensive position. He has already reneged once on his commitment to accept Muller's findings. This latest announcement backs him into an even smaller corner.

To many who work in the field, Muller's latest announcement merely brings him up to date with where the science was in the mid 1990s.
At this rate, Muller should be caught up to the current state of climate science within a matter of a few years!

This  event has me thinking of those wonderful defensive structures - the medieval castles of Europe and the Middle East.

Kidwelly Castle, Carmarthenshire, Dyfed, Wales, is a great example. Like most castles, it was constructed in a location with natural defences. Kidwelly was originally a timber castle built by the Normans about 1100 on a prominent ridge overlooking the river Gwendraeth.



Over the centuries it was rebuilt in stone and embelished with new defensive features.



For more than 400 years Kidwelly Castle provided a safe place for citizens to retreat when attacked and  housed garrison forces that could sally forth to attack mauraders and fight rivals. Its river, moat, steep berm leading to castle walls, towers, gates, parapets and other defensive features made it relevant and effective.

If an outer defence was breached, the defenders moved back to the next line of defence. If it came to the worst, defenders could withdraw to a single tower where they could hold out in the hope that relief forces would come to their aid.

Climate change deniers have the same approach to defending the Denier citadel. Here are the defensive lines around the citadel.
  1. The outermost defence is an earth berm where the mass of defenders rattle their spears and chant, "It's not warming! It's not warming!"
  2. The next line of defence is the moat where the defenders shout, "It's warming but it's not us! It's the sun! It's water vapour! It's a natural cycle! It's a squirrel!"
  3. Then there are the outer walls of the castle, where diminished defenders run to and fro shouting, "It's warming, we did it, but it's not a big problem. Warm is nice, CO2 is good for plants, Greenland was lovely in the medieval warm period."
  4. Then there is the inner wall of the castle, where the handful of remaining defenders stumble around muttering, "Yes, it's warming; yes human activity is the cause; yes, it will be horrible - but mitigation is too hard/expensive, so let's plan to adapt instead."
As each defense is breached, some of the defenders have their 'road to Damascus' moment and become advocates for action. Others fall back to the next line of defence. A few lost souls remain forever in No Mans Land crying in the wind, "It's not warming!" and "Look! It's a squirrel!"

Time passes and by 2050 the Denial citadel will be as irrelevant as the ruin of today's Kidwelly Castle. However, while Kidwelly Castle leaves a beautiful monument to the necessities of past culture, the relic of the Denier Citadel will be a monument to shame.

UPDATE: Anthony Watts's response to the Muller announcement was, "Look! It's a squirrel!" Maybe he thinks that's a useful tactic at any of the the defence lines - the berm, the moat, the outer and inner walls. Maybe he will still be shouting "It's a squirrell!" when the last defenders are holed up in the last tower. Or maybe he has joined the lost souls in No Mans Land, crying out for relevance.

How much air in the tank?


Scuba divers pay a lot of attention to the amount of air in their tank. Their lives depend on it.

In the same way, climate scientists are keeping a close eye on the amount of greenhouse gases in the atmosphere. Whereas scuba divers are concerned when their air supply runs low, scientists are concerned when the amount of greenhouse gases gets too high.

Scientists have calculated how much more CO2 we can add to the atmosphere and still stay within the limit of 2C warming. They calculate that the atmosphere can hold an additional 565 GT (gigatons) of CO2.  Two degrees centigrade is the target that world nations have agreed upon as a target. Scientists say this will give a 50% chance of avoiding the worst consequences of global warming.

Two degrees is not a get out of jail card, with 2C we have 100% chance of getting all the serious consequences of global warming (increased drought, heatwave, flooding, ocean acidification, storms and floods, and rising sea level) as well as a 50% chance of copping the very worst (massive loss of arable land, loss of coastal cities, mass species extinction, runaway global warming).

565 GT is the equivalent of about 15 GT a year between now and 2050. However, the IEA reports that the world emitted twice as much last year (31.6 GT in 2011) and the trend is rising. These figures give rise to two thoughts:
  • At current emission levels, we will reach the 2C 'safety' target by 2030 and extreme weather events will have quadrupled.
  • We need to halve our emissions right now and then reduce them to zero by 2050.
When a scuba diver's tank is running low, they don't ignore it ("Faulty dial, always lies"), or negotiate with it ("Come on, tank, give me another 30 minutes and I'll give you a shiny hologram sticker to make you look pretty.") or threaten it ("Give me more air or I'll kill your wife and children. I know where you live.")

It's the same with 565 GT. We can't ignore it or try to negotiate or threaten it. Yet this is exactly what the fossil fuel industry is doing. They are sitting on current known reserves of coal, oil and gas that would pump 2,795 GT carbon dioxide into the air if burnt. And they are busily looking for more - ExxonMobile spends $100 million every day on exploration for new reserves.

With a limit of 565 GT, the remaining 80% (2,230 GT) will be left in the ground as stranded assets unless carbon capture becomes economically viable.

The new Laggard to Leader report from Beyond Zero Emissions asks Australia to take the lead in recognising that 80% of the world's fossil fuel reserves cannot be used by putting a moratorium on new coal exploration and mining. Australia currently dominates world coal with 27% of all trade so our actions can have a big impact.

When Australia stops expanding its coal industry it will be like the scuba diver who recognises his tank is getting low and starts heading back to the surface.  At that point we'll be swimming hard, hoping we make it in time to avoid catastrophe.

Saudi Arabia announced that it would install 41,000MW of solar over the next two decades (25,000 in solar thermal and 16,000 in utility-scale solar PV). The Saudis are not wasting time – there’s too  much money to be saved. The cost of the initiative is estimated at $100 billion, but it is estimated to save 523,000 barrels a day, or more than $19 billion a year at current oil export prices). This month the Saudis announced that the first of their solar auctions, totaling 2,000MW, will be held early in 2013. The second round of 2,500MW will be held in 2014. Source: Reneweconomy.

Blessing the fleet


The ancient practice of blessing the fleet continues to bring comfort and ceremony to modern lives. This picture shows the modern fishing fleet in the small NSW town of Ulladulla getting its annual belssing. Apart from being a tourist attraction, blessing the fleet is also an example of magical thinking like our little practices of 'touch wood', crossing fingers, careful references to the 'Scottish play', or religious prayer practice.
 
I don't mind the colourful ritual of fleet blessings because I know that these ceremonies do not displace laws that require ships to be sea-worthy, to carry adequate safety equipment and for crew to be suitably qualified. The real work of blessing the fleet is done by the lawmakers and bureaucrats who set standards and ensure the fishmen stick to them.

While lawmakers have been active in ensuring safety at sea, they have been quite lax in giving us laws that require greenhouse gas pollution to be curbed to levels recommended by the best scientists on the planet. In the case of recent droughts, bushfires, storms and flooding, all exacerbated by climate change, we have been left to rely on church prayers. In the recent 10-year drought in NSW,  church congregations prayed for rain every week.

These prayers had questionable effect on the drought and were remarkably useless at reducing a prime cause – Australia's greenhouse gas emissions. We continue to top the list of world's worst emitter at 19 tonnes per capita.

Under a business as usual scenario, the Bureau of Meteorology predicts that NSW will be 3-4C warmer by 2070. This will quadruple the number of extreme weather events like droughts, heatwaves, violent storms, floods and bushfires. Ocean acidification will wipe out fish stocks so the fishermen of Ulladulla won't need a blessing because they won't be going to sea.

One can only hope that these events trigger a mass outpouring of magical thinking in the form of prayer rallies. Perhaps that will inspire our legislators will get to work to address the root cause of the problem by enacting legislation to lower our greenhouse gas emissions. Fingers crossed.

The US has cut carbon emissions more than any other country in the world in recent years — down 7.7 percent since 2006.  By the end of 2012, US carbon emissions will be the same as in 1996. Reductions are due to lower oil use in the transport sector (linked to efficiency improvements, higher oil prices and the economic downturn which has cut vehicle miles travelled) and a substantial shift from coal to gas in the power sector.

Journey of Possum and Sugar Glider (2)

The Journey of Possum and Sugar Glider began here. After the Guru told Possum that he had to reduce his carbon emissions before he could find Nirvana, Possum met up with Sugar Glider and a small band of travellers. He learnt about the danger to the world and the value of compound interest.



4. Spoilt for choice, what to do first?

Possum's head buzzed with all the things he could do to reduce his carbon emissions. He thought of little things like turning out lights through to big things like buying a new car or growing his own vegetables.

He got out an old notebook and started making a list.
  • Turn out lights, change to low-energy lights
  • Change to an energy efficient car
  • Walk to the local shops instead of driving
  • Look getting better heating

He filled pages and pages, then he went online and checked for advice offered by his local government, Becoming a ClimateClever Home is as Easy as 1-2-3.

He filled more pages then he began to slow down. Finally he stopped.

"There!" he thought, "That's a good morning of work. Time for tea."

While he waited for the kettle to boil, he flicked through the pages and "Easy as 1-2-3" repeated in his mind. "Not exactly as easy as 1-2-3," he thought, "It's going to take me months to do all this. What should I do first?"

Just as the kettle was boiling, he had a bright idea. He decided to ring Sugar Glider and invite her over.

He smiled as her phone started ringing.


To be continued....

It's raining metaphors


Now that the US is suffering unprecedented extreme weather events, including heatwaves, drought, wildfires, storms and floods, their mainstream media is paying attention to climate change.

It helps that NOAA just released an important new report that shows the connection between specific extreme weather events and climate change.

ClimateProgress reports that all mainstream media have reported the connection between extreme weather and climate change. 

Bill Blakemore on the American ABC News website gives journalists a lesson in how to talk about the link between climate change and extreme weather. He uses three metaphors that have the stamp of approval from real scientists.

Here's a quick overview.

The Parable of the Pot. He uses a pot of boiling water to illustrate that turning up the heat results in more bubbles in the water. Scientists won't say that any particular new bubble is caused by turning the heat up, but they will say that the probability of more bubbles is increased when you turn up the heat.

Baseball Player on Steroids. This short animation shows that when a baseball player takes steroids his run rate is higher (featured earlier on this blog here). You can't say that any individual run is due to the steroids, but the player gets higher run totals due to the steroids. They ban steroids to prevent this. In the same way, we need to reduce greenhouse gas emissions to prevent extreme weather events.



Loaded Dice. This analogy shows that climate change increases the odds of extreme weather events. It has been used consistently since 1988 when James Hansen took two painted dice to his presentation to Congress. We featured it earlier on Thisness of a That, here.

Blakemore offers a phrase that everyone can use to describe the link between climate change and extreme weather events without using the 'cause' word,
This exactly fits the pattern long predicted of increasingly frequent severe weather events.

In contrast, Dan Lashey from the National Resource Defence Council argues that we can come right out and say: Carbon pollution causes extreme weather. He notes that cigarette packs no longer say tobacco 'may cause harm', they say: Smoking causes lung cancer.

If newspapers can report that 40 people died because of a heatwave, I don't see why they can't report that an extreme weather event was caused by global warming (or climate change or carbon emissions). 

We can expect to see more variations on these statements as mainstream media tackles the task of connecting the dots between climate change and weather.

UPDATE: Paul Krugman uses the Loaded Dice analogy in this piece in the New York Times where he concludes: 
... large-scale damage from climate change is no longer a disaster waiting to happen. It’s happening now.
