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.

geoengineering been legitimised by the IPCC?

“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.”
