The dog that caught the car... now what?

Bark like hell and chew the bumper...

The heighten trepidation [1] felt by many (including me, hence the title of this post) is understandable now that geoengineering has begun to be officially addressed by the IPCC. [2]
 
In the first of three installments of its latest report, the AR5, concepts for CARBON DIOXIDE REMOVAL (CDR) [3] and SOLAR RADIATION MANAGEMENT (SRM) [4] are introduced while more details are expected in future reports.

Even though it seems that the ‘science report etiquette’ was broken by the inclusion of these GE concepts on the AR5’S WORKING GROUP I contribution, it is useful precisely because it flushes out the overall latent attitudes towards GE in a more official manner, and equally important; the attitudes towards those alternatives downplayed i.e. aviation emissions [5] [6] [7] and short lived climate pollutants. [8][9]

I hope the IPCC finds a way in the upcoming reports from working groups II and III to explore in detail and to convey a sense of urgency on the effectiveness of these alternatives to GE in dealing with climate change.

I hope that those in the scientific community and media who are genuinely opposed to geoengineering also find a way to communicate in their critical pieces that there are viable alternatives, because ignoring them, as it has mostly been done so far, may help to wrongly frame GE as THE 'answer' to climate change.

[8] Pioneering black carbon researcher receives U.N. ‘Champion of the Earth’ award
Sep 27, 2013
“Veerabhadran Ramanathan, a distinguished professor of climate and atmospheric sciences at Scripps Institution of Oceanography, UC San Diego, whose landmark research showed that cutting emissions of black carbon and other short lived climate pollutants can significantly lessen the impacts of regional and global climate change, improve the health of millions of rural poor, and avoid crop losses, will receive tonight a 2013 Champions of the Earth award, the United Nations’s highest environmental accolade.”
