The Height Of Temperature Folly

WUWT
Note that in all cases, these are the optimistic numbers, in which the supposed reductions in CO2 emissions are assumed to continue after 2030 all the way until 2100.
Of particular interest to me was the impact of the Obama War On Coal, or as it is known, the US Clean Power Plan (USCPP). Even if we can implement it, and then assuming we can follow it until 2100, the total reduction in temperature rise is estimated to be 0.013°C.
Now, that’s a bit over a hundredth of a degree Celsius. The problem is, nobody has a good handle on just how small that reduction in temperature actually is, because we have nothing to compare it to. Even fever thermometers only measure to a tenth of a degree. Casting about to rephrase this number in units that might be more understandable than hundredths of a degree, I remembered the old rule of thumb about how much the air cools off as you climb a mountain. Everyone knows that as you go up a mountain, the air gets cooler. The rate at which non-condensing air cools with increasing altitude is called the “dry adiabatic lapse rate”. The rule of thumb states that for every hundred metres higher that you climb, the temperature drops by 1°C.
Now, a human being is typically around 1.7 metres tall, plus or minus. This means that other things being equal, the air at your head is about 0.017°C cooler than the air at your feet. And recall from above that the “impact of the US Clean Power Plan (USCPP) is a reduction in temperature rise by 0.013°C by 2100” …
Which means that after spending billions of dollars and destroying valuable power plants and reducing our energy options and making us more dependent on Middle East oil, all we will do is make the air around our feet as cool as the air around our heads … I am overcome with gratitude for such a stupendous accomplishment. Seriously. The sum total of the entire restructuring of the US energy production will be to make the air around our feet as cool as the air around our heads."
