In my previous posting, "Fixing Soot Gains 20 Years against Global Warming" I found myself omitting some rather surely controversial comments in hopes the idea gains acceptance and distribution. I truly believe it's a win-win proposition for everyone concerned about global environmental problems whether they be industrialists or environmentalists. Airborne soot falls from the air in a matter of weeks, so its abatement is perhaps even more efficacious than curtailing CO2 emissions in terms of cost effectiveness and tangible environmental benefits.

The odds are poor that humanity will ever curtail CO2 emissions sufficiently fast against even the mid-case global warming scenarios forecast by climatologists. A possible near-term remedy, however, has been found in the form of a simple pollution abatement strategy in the mitigation of airborne soot. Airborne soot falls from the air in a matter of weeks, so its abatement is far more efficacious - in terms of tangible environmental benefits - than first migitating CO2 emissions.

Ramanathan has served on IPCC WG2 Panels, he headed the UN's INDOEX project and he's as solid a climate scientist as we have.

Airborne soot's heating effects have been found to be 60 percent of CO2's, yielding a 40/60 soot/CO2 global atmospheric heating combination. In higher altitudes soot is just as important as CO2 in melting tropical glacial packs like the Himalayas (and perhaps Kilimanjaro) while also devasting Arctic ice by making it more heat-absorbant.

INDOEX lead researcher V. Ramanathan has co-authored a paper on his team's findings that airborne soot (aka black carbon, or BC for short) plays a far greater role in atmospheric warming than the UN's IPCC reports have yet indicated.

Overturning the conventional theory that airborne soot emissions cause regional cooling it has been found that brown clouds of airborne soot can contribute up to a third of atmospheric warming anomalies in the tropics formerly ascribed to CO2 (50 percent of the atmospheric heating caused by CO2 emissions), with its effects ranging as far as the more-temperate American west coast and mountains ranges.

Easily 40 percent of the observed atmospheric warming in the Pacific is due to the shroud of soot drifting eastward from Asia. Prof. V. Ramanathan and fellow researchers are reporting that soot's 2.5 W/cu.m. green house effect is partially offset by its surface dimming effect, such that its net effect is still 1 W/cu.m. With the vast Pacific covering 30 percent of the Earth's surface, aerosol soot - black carbon particulates - plays a significant factor in global warming, potentially 12 percent of all global warming.

Increased solar radiance and decreased snowfall have been implicated as the true culprits in Kilimanjaro's glacier loss. The temperatures on Kilimanjaro's summits almost never rise above freezing, leading researchers to look for other causes for the ongoing glacial recession on Kilimanjaro's peak. Other studies have suggested that deforestation has severely impacted the arboreal microclimates that provide recharge precipitation to Kilimanjaro's glacial packs.

U.N. officials have stated that Kyoto's carbon-credit system is being subverted via cheating while contributing to the destruction of the ozone layer - counter-productive to the Montreal Protocol's goal to preserve it.
