Guest essay by Ed Hoskins.
Some simple numbers on the effect of CO2 concentration on temperature
As the temperature increasing effect of atmospheric CO2 is known to diminish logarithmically with increasing concentration, these notes clarify the actual amount of warming that might result from additional CO2 released into the atmosphere by man-kind and the temperature reduction impact of any policy actions to control CO2 emissions.
To understand exactly what might be achieved by political action for de-carbonisation the table below gives the likely warming, (without positive or negative feedbacks), that will be averted with an increase of CO2 from 400 ppmv to 800 ppmv, a full extra 400 ppmv, assuming that the amount of CO2 released by all world nations in future is reduced in future by 50%.
It shows the impact of the following countries or country groups with the range of both sceptical and alarmist assessments.
So the impact for the whole of the EU (27) is somewhere between 9 -73 thousandths of degree Centigrade and for the UK the range is between 1-9 thousandths of degree Centigrade.
To achieve this irrelevant and miniscule result the UK, European and other free world governments are willing to annihilate their economies to solve a problem that does not exist.
Western politicians should, “Have the courage to do nothing”.

Lancelot: Don’t be naive. It is known that the delta t between the tropics and poles causes weather extremes. As the average world temperature declines, it gets more cold in the norther hemisphere there is a larger gradient of temperatures between the tropics and poles. Observations clearly back up this notion. So please admit that you now understand this and retract your statement.
Mario, which observations are those?

Seriously: You don’t know that without delta t, storms would not occur? I’ll let you ask around or perhaps talk to a meteorologist. Anyone doubt this?

The whole point of our discussion was about Albedo
so why the &*$&% are you talking about summer sea ice in Antarctica? To properly gauge the change in albedo we need to add the summer sea ice anomaly for the northern hemisphere to the winter sea ice anomaly for the southern hemisphere. This tells us what the difference in albedo is for the planet.

Best to use named months, since Summer in the NH is Winter in the SH.

A “variable” to include in you’re considerations is that one of the things the Enviros have vilified, aside from CO2, is chlorine disinfection of drinking water. The overly hyped “dangers” of disinfection-by-products, such as trihalomethanes, has led some third world countries (most of which are in the Southern Hemisphere) to eliminate or reduce chlorine disinfection without replacing it with something that would leave a residual in the water that would keep water-born pathogens such as cholera from reinfecting the water.
TYPO! “in you’re considerations” should be “in your considerations”.

add September arctic ice anomaly to March Antarctic ice anomaly (both minimums) since that is when the albedo is interacting with the sun.

1) Winter sea ice in Antarctica was also above average so stop pretending you do not understand or finding other excuses, it is there at the link posted and you can see it in the WUWT reference pages.

2) Antarctica sea ice goes to lower latitudes then in the north so the albedo effect is stronger.
