Things taking a turn for the worse. Monsoons could be over for many parts of India for eg. Rivers fed by glaciers dry up to trickles.

I’m not interested on CO2 very much. What is much more interesting for me are lower or no SO2, NOx, PAH, NH3, dioxin, particle of any size, … emissons.

Massachusetts Institute of Technology (MIT) researchers recently announced the discovery of a pollution free method of steel making. CSE investigates how green the process is. Analysis shows the process is not quite as CO2 emission free as claimed. For more:

A third of the world’s steel is actually recycled, in smaller electric arc furnaces feeding minimills for rebar and beams – the majority of plants by number. I don’t suppose the latter process emits much CO2.
