Perspective

The world or at least the western world seems to be having a mass frenzy of self examination about the environment. The young girl that seems so angry about everything and is blaming big business (or so it seems to me, but it could as well be grown ups generally) for ruining her future is embarrassing large global enterprises into having a more eco-friendly corporate policy. It seems to be working (the embarrassing bit, not sadly the actual impact on anything bit) at least in the UK where all political parties are promising zero carbon this and that by what seems like the middle of next week if the electorate just vote for them at the 12th December general election. This is all just fine as I believe that the world is in an environmentally sticky position and something needs to be done. It's just that perspective is massively missing and the action is being focussed on in all the wrong places.

Now I don't want to sermonize, rant or moralise about things, particularly the rights and wrongs of the whole environmental question, but it does seem to me that turning off lights or no longer using single use plastic bags doesn't really help much despite what the media and environmental activists may say. This isn't a popular position to have but I recently found someone that agrees with me. Here's an excerpt (read the whole thing here):

But we aren’t very good at thinking about scales and proportions. In general, I think, we assign things a value of ‘good’ or ‘bad’, and bracket them all together in those two categories. For instance, we feel good when we take a bag-for-life to reduce plastic bag use. But you can make 1,000 bags for 6kWh, while boiling a kettle takes about 0.1kWh, so you could make 16 plastic bags for the energy cost of just one round of tea.

From a purely climate point of view, your plastic bags are largely irrelevant. Reducing plastic waste is also good, of course, although again, Western countries account for a tiny fraction of the ocean pollution we worry about — almost all of it comes from Asia and sub-Saharan Africa, in fact.

This last comment caught my eye for as someone spending a lot of time in Penang, Malaysia, I see the evidence of this every day. The above article redirected me to the underlying statistics (see here) from the Our World in Data website from which I found a whole raft of data supporting this position. Basically, if nothing changes to the way in which pollution of all sorts is made, anything done by virtually anybody in the West is simply a rounding error.

Now...
... and projected

What a dismal prospect and I will leave you with this additional factoid:

None of this is meant to make you stop taking care over the small things: look after the pennies and the pounds will look after themselves, as they say. There’s nothing wrong with stopping using plastic bags, although you need to be very careful that you don’t lose your cotton bags-for-life, since they use about 100 times as much energy to make.

Keep your perspective.

Haze. Pea Soup.... let's just call it Pollution.

This last week has been unpleasant so far as the weather is concerned. It is the time of year that Indonesian farmers burn fields to make ready for new planting to take place in a few weeks time. The foliage has dried out so it is much easier to simply burn the scrubby bits left over from last year than manually prepare the ground. So they burn. They don't have to do this and in fact there are laws forbidding this practice, but it still happens and nobody takes action. It's not new news out here but it is in the West. This is what the BBC has to say about it.

Penang is highlighted. The wind here is negligible for the next few days so we will be suffering from this haze for a while yet
It has been going on forever and this is the time of year that it all takes place. For Penang, the areas that most affect us are in Sumatra and with the South West monsoon season here until Christmas, the SW winds that prevail are simply pushing this ghastly messy.... haze all over us. It wasn't anywhere like this last year from memory; apparently it is really bad this year.  Even Bloomberg is paying attention.


I remember growing up the fogs or rather pea soupers in the towns in England. Dense fogs that would hang around for days. For those of you that do not know about these, here is Wikipedia's comment. These fogs were brought about by the coal burning that everyone did in those days (and people wonder why coal has become bit by bit an untouchable fossil fuel) and it wasn't until the 1950's that policy action actually did anything about it. I remember our shirt collars being coated in grime and coughing continuously and the phlegm. Yuk, it was black. Respiratory diseases were prevalent everywhere. I had whooping cough when I was really young and coughs and colds all the time later on.  Pneumonia, TB were everywhere. Mind you every adult still smoked like chimneys.

The tipping point was the pea souper of 1952 which is shown here at Piccadilly Circus. You wouldn't know it was but you can see Eros to the left.
The important takeaway from the above is that regrettably it took 'policy action' to do anything about the pea soupers in England.... aka government intervention by law. I recently read an interview with a very prominent engineer who ran BP for many years (here is the full interview transcript) whose view on the world was from a very engineering viewpoint, of course, but the context was that companies would not do anything until policy makers make them. The technology to fix things is all there but it is not being used because companies don't have to.  Here's an edited excerpt:

JOHN BROWNE: Well ...oil or wood or cutting down forests, but also giving people a very different modern way. So... we’ve created a problem and I’ve been on this point for almost a quarter century now saying... it’s the oil and gas industries that’s created this problem and we need to fix it. And the way to fix it is not to stop engineering, is to apply more engineering to solving the problem...And actually, in this area, I would say that we have already all the engineering processes to stop pumping ... CO2 into the atmosphere and actually even to clean up some of the CO2. The problem is that the ...engineered products are too expensive until they are all rolled out in massive scale because …This is where policy comes in. So in other words, policy has to push these …new engineered products to the point where they become more economical. You don’t have to invent, we need to apply and this is where engineering is very good because as you apply more and more, so the unit cost comes down. We know that for sure. So you need a policy lever... the biggest policy lever you need is a price on carbon. Carbon taxes...have got to be priced high enough so that people can and will actually do something to get it out of the system.

The argument that fixes cost money simply don't wash. This was the argument the car industry used in the 1960's but the lead pollution laws were passed and the issue went away. The car industry is now running pell mell to be the first to produce mass market electric cars.

So all of this is both avoidable and fixable. Granted the developing nations don't want to hear developed nations who polluted away years ago sanctimoniously tell them what to do. But the alternative is pretty desolate.

This week versus normal times
