                       BRINGING AGW DOWN TO EARTH

OVER AT ATTP
Michael Tobis and I have been discussing the pros and cons of focusing  the attention of individuals  on their share of the global commons- few realize that their share of the air is the better part of a million tonnes, or that the CO2 in it could be turned into a block of dry ice roughly the size of a SUV

RealClimate often complains with cause about  efforts to denigrate the significance of CO2:

The basic facts about the global increase of CO2 in our atmosphere are clear and established beyond reasonable doubt. Nevertheless, I’ve recently seen some of the old myths peddled by “climate skeptics” pop up again. Are the forests responsible for the CO2 increase? Or volcanoes? Or perhaps the oceans?Let’s start with a brief overview of the most important data and facts about the increase in the carbon dioxide concentration in the atmosphere:

  1. Since the beginning of industrialization, the CO2 concentration has risen from 280 ppm (the value of the previous millennia of the Holocene) to now 405 ppm...

Several commenters observed that this works out to about a kilogram per square meter of man-made CO2 globally, raising an interesting  educational possibility: turn the  kilogram-per- square-meter meme into a public art theme.

Passers-by given to parroting   playbook mantras like :
 " What can  four hundredths of one per cent of  the  invisible Gas of Life  possibly do ? " 
could be politely invited to step into a one square meter plexiglass telephone booth with a wet floor, to  elicit a Holy Smoke! reaction when a kilo of powdered dry ice  is sprinkled at their feet.

A major museum courtyard might host  a pyramid  of  stacked dry ice blocks containing one person's share of the anthropogenic  CO2 they add to  the air -  about 20 tonnes  of the stuff.

Infrared thermal cameras  could set up upwind and downwind of  the  two story tall pyramid, and  flat screen displays  could allow passers by to see their  thermal glow disappear  as  IR opaque plumes of CO2 waft between them  and the  thermal imaging cameras.
This would turn your share of the CO2 problem into something easy to see and mighty hard to ignore:
