I endorse the views of Areej Saqib in his letter captioned 'Do more' dated 22.7.2009. Setting the average goal of 3.6 Fahrenheit as the absolute maximum that the earth should be allowed to warm, seems not wise.
Contrary to this, we must consider that when at one location the emission of green gases is more than 7 degrees Fahrenheit, at many other location it is very low, so that the average drawn is not be consistent. The earmarked average is much higher.
The big industrial countries cannot be pressurised to decrease emissions, unless they voluntarily take strict measures. Let the greenhouse gases be on the rise satellite technology may find some concrete solutions to this problem. This idea arose after reading a news item in Business Recorder on March 2nd, 2009, Carbon dioxide mapper (with photograph of satellite).
When Nasa can build such a satellite, which can use spectrometers to create a detailed picture of the world's carbon sources, and reservoirs and is an orbiting carbon observatory, then Nasa's brains, together in collaboration with technocrats of other advanced countries can undertake to build such a sophisticated satellites, which can "sweep, absorb, collect and dispose of" greenhouse gases from the global atmosphere.
I think there should be 24 or more satellite orbiting around the globe one, after another, mostly over the heavily industrialised countries, collecting warmth and greenhouse gases from their atmosphere and disposing them of, at the remotest far off regions in space. Let us hope that perhaps Nasa can see anything useful in this idea.
