From Climate Scepticism<\/a><\/p>\n\n\n\n

By\u00a0Jit<\/a><\/strong><\/p>\n\n\n\n

Are there any?<\/em><\/strong><\/p>\n\n\n\n

This week came the news<\/a> that permission for the Rosebank and Jackdaw fields was unlawful, owing to a failure to take into account the effect of downstream emissions, i.e. the combustion of the extracted products.<\/p>\n\n\n\n

It may seem curious that this matters; everyone knew at the outset what the purpose of the permission was, and that a large chunk of what came up from the deeps would ultimately go up in smoke. But some people saw the chance to put a stop to these new fields after the case of Horse Hill went to the Supreme Court<\/a>, where it was decided that downstream emissions must be taken account of when deciding permission.<\/p>\n\n\n\n

In my view, this position is nonsensical. At the moment, our civilisation depends on the products that Rosebank and Jackdaw would have provided. It provides the grinning idiots who successfully brought the new case with the means to do so. Without oil, civilisation collapses, and successes at the Supreme Court count for naught. Rather than engaging in learned debate, by that point, we\u2019re fighting over the last bag of Bonios \u2013 and they ain\u2019t for our pooches. Thus, it seems particularly self-defeating to attempt to block new oil fields. As a wealthy country, we are partly insulated against such stupidity thanks to our ability to buy oil from other countries. For anyone to think that blocking Rosebank and Jackdaw is good for our country is Baldrick-level stupidity. It is like the child who thinks he becomes invisible when he closes his eyes. We will import the needed oil from further away, and who knows, maybe part of it will come from dictatorships, and perhaps the environmental protections where it is ultimately drawn from will be weaker. Then, it has to be transported here. You cannot ban this substance until you no longer need it.<\/p>\n\n\n\n

Rather than argue the toss about whether downstream emissions ought to have been considered by the planning authority, the court could simply have asked what effect those downstream emissions might have \u2013 to see whether they were even worth considering. Both sides could have produced a stubby pencil and calculated the influence of these new fields on the Earth\u2019s climate. Then, if there was a gap between them, they could have argued the toss about that, until their estimates drew closer.<\/p>\n\n\n\n

But they didn\u2019t.<\/p>\n\n\n\n

So, in the spirit of trying to find out the facts, I offer this calculation to estimate the effect on climate of the Rosebank field. It cost me only time, a cup of coffee, and a few electrons. I wonder how much the green lawfare has cost so far?<\/p>\n\n\n\n

Gathering numbers<\/h4>\n\n\n\n

In Into the Unknown<\/a><\/em>, I laid out some basic facts about carbon dioxide in the atmosphere. The interested reader can find there: the mass of the atmosphere; the mass of carbon dioxide in the atmosphere; the mass of carbon dioxide representing 1 ppm in concentration; and the basic equation to calculate the temperature change caused by a change in CO2<\/sub> concentration, given what I considered to be generous (to the cause of alarm) parameters. There, I noted that Wiki states that 57% of emissions of CO2<\/sub> are absorbed by the biosphere; I called it 50%, again to favour the cause of alarm.<\/p>\n\n\n\n

What about Rosebank and oil? According to the BBC<\/a>, Rosebank holds 300-500 million barrels of oil. Let\u2019s say 500 mil are extracted, to favour the cause of alarm. The internet says that a barrel of oil has a mass of 136 kg. Radovic <\/a>gives the mass proportion of oil that is carbon as ~85%.<\/p>\n\n\n\n

With these numbers, we are ready to make our calculation.<\/p>\n\n\n\n

Temperature change caused by Rosebank<\/td><\/td>0.000092<\/td>K<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Combustion of all of the higher estimate of Rosebank\u2019s oil would lead to an atmospheric temperature rise of ~ 1\/10,000 of a kelvin. The calculation is made with parameters favouring the cause of alarm. It does not account for the fact that not all oil is burnt. Some is sent to the petrochemical industry, or used as lubricants, or ends up being spread on roads, etc. However, since 0.000092 K is not a significant temperature increase, indeed it will not be measurable, there is no case to prevent Rosebank from being permitted.<\/p>\n\n\n\n

The folks that oppose this prefer other metrics to temperature change when they are critical of projects. Millions of tonnes of CO2<\/sub> sounds far more frightening that a ten-thousandth of a degree. On another thread, Jaime gives the number<\/a> of 10.5 million tonnes of CO2<\/sub> as the downstream emissions of Horse Hill, which was enough to stifle that project. What temperature rise might that be? Well, I\u2019ll tell you. Using similar reasoning to that given above, it\u2019s 1\/200,000 of a degree kelvin \u2013 again, given alarm-favouring parameters.<\/p>\n\n\n\n

And this is why the metric of tonnes of CO2<\/sub> is the preferred one: translated into temperature change, the numbers are trivial. They are theoretical \u2013 far too small to be detected.<\/p>\n\n\n\n

It\u2019s time these jokers stopped posing triumphantly on the steps of the Courts, chests puffed out like Washington crossing the Delaware. They need to recognise that their lives, and the lives of those they love, rely on the very thing they just gave a kicking.<\/p>\n\n\n\n
