Challenge to Climatologists?
by: Rob FIt is proven that aerosols and other particulate matter such as cloud cover scatter or reflect radiation. In the case of reflection, energy is reflected at the same angle at which it hits an object.
Because of this process, aerosols are responsible for cooling the troposphere. If aerosols were not a product of human activity, then we would see temperatures now as hot as 2070 is projected (Source: MIT Technology Review, Aug. 06)
Worldwide, aerosols are produced mostly by car exhausts and the burning of organic material.
My question to climatologists is, at what point should we mobilize economic resources to produce and manage constant aerosol emissions?
When will we admit that global CO2 emissions will not be cut enough to save the Antarctic?
Sequestering greenhouse gases from coal is decades off from wide-scale implementation.
We all saw what happened to mean temperatures during 9/11′s no-fly rule.
Why do PACs ignore aerosols when speaking to the general pub.?

The following details say that aerosol emissions will come down by 2030 and 2050. Climatologists are on the job!

On the future of carbonaceous aerosol emissions
The paper presents the first model-based forecasts of future emissions of the primary carbonaceous aerosols, black carbon (BC) and organic carbon (OC). The forecasts build on a recent 1996 inventory of emissions that contains detailed fuel, technology, sector, and world-region specifications. The forecasts are driven by four IPCC scenarios, A1B, A2, B1, and B2, out to 2030 and 2050, incorporating not only changing patterns of fuel use but also technology development. Emissions from both energy generation and open biomass burning are included. We project that global BC emissions will decline from 8.0 Tg in 1996 to 5.3–7.3 Tg by 2030 and to 4.3–6.1 Tg by 2050, across the range of scenarios. We project that OC emissions will decline from 34 Tg in 1996 to 24–30 Tg by 2030 and to 21–28 Tg by 2050. The introduction of advanced technology with lower emission rates, as well as a shift away from the use of traditional solid fuels in the residential sector, more than offsets the increased combustion of fossil fuels worldwide.
