Hi all
Black carbon gives a short-lived climate forcing if it is covered by a
fall of nice new clean snow.
But if there is lots of snow melt many old layers of black carbon and
volcanic ash will get exposed.

*New report highlights SLCF emissions in the Nordic countries*
/Conclusions and recommendations on Nordic actions against Short-lived
Climate Forcers: New report produced as a follow up to the Svalbard
Declaration from the Environment Ministers in the Nordic countries*.*/
High concentrations of Short-lived Climate Forces such as black carbon
may have a large impact on global warming, especially for the Arctic
region. The good news, however, is that early reductions of such
pollutants could reduce the speed of global warming in the short term.
Emission reductions will also have important health benefits.
Realising that global emissions of SLCFs can only be effectively
abated through broad international, regional and national initiatives,
the Nordic Ministers of Environment from Denmark, Finland, Iceland,
Norway and Sweden adopted " the "Svalbard Declaration" in March 2012
and agreed to improve the basis for national and joint Nordic
initiatives.
To support the work initiated by the ministers, the Nordic Climate and
Air Quality Group under the Nordic Council of Ministers has now
produced a new report with nine specific policy recommendations on
immediate Nordic actions, Nordic campaigns and international actions.

*Background *
Recent scientific findings have identified that the so-called
Short-lived Climate Forcers (SLCFs) such as black carbon (soot) might
have a larger impact on global warming than earlier assessments have
indicated, especially for the Arctic climate, resulting in rapid
melting of snow and ice in the Arctic region. Abatement of these
emissions would reduce the speed of global and Arctic warming.
The Nordic Climate and Air Quality Group under the Nordic Council of
Ministers held a seminar in June 2012 where scientist and
policy-makers discussed recent scientific developments and on-going
activities related to SLCF's. This included national experiences with
emission inventories, identification of cost-effective measures to cut
emissions and the drawing up of national action plans as well as the
development in the field of international co-operation on SLCFs.
In addition, the workshop adopted a number of conclusions and
recommendations on scientific research, monitoring and modelling
underlining that particular emphasis should be directed towards the
Arctic region, and the need to intensify collaboration with Russia.
All presentations at the workshop are also included in the report.
