The
Threat of Wildfires in the North
27
June, 2013
A new
map has
been issued by NOAA/NASA. The map shows that most vegetation
grows in two bands, i.e. the Tropical Band (between latitudes 15°N
and 15°S) and the Northern Band in between 45°N and 75°N, i.e. in
North America, Europe and Siberia. On above image, the map is roughly
overlayed with a grid to indicate latitude and longitude
co-ordinates.
Vegetation in the Northern Band extends beyond the Arctic Circle (latitude 66° 33′ 44″ or 66.5622°, in blue on above image from Arcticsystem.no) into the Arctic, covering sparsely-populated areas such in Siberia, Alaska and the northern parts of Canada and Scandinavia. Further into the Arctic, there are huge areas with bush and shrubland that have taken thousands of years to develop, and once burnt, it can take a long time for vegetation to return, due to the short growing season and harsh conditions in the Arctic.
Above map with soil carbon content further shows that the top 100 cm of soil in the northern circumpolar region furthermore contains huge amounts of carbon.

Global
warming increases the risk of wildfires. This is especially
applicable to the Arctic, where temperatures have been rising faster
than anywhere else on Earth.
Anomalies can be very high in specific cases, as illustrated by the
temperature map below. High temperatures and drought combine to
increase the threat of wildfires (see above image showing drought
severity).

Moscow broke its more
than 100-year-old record for
the hottest June 27

Zyryanka,
Siberia, recently recorded a
high of 37.4°C (99.3°F),
against normal high temperatures of 20°C to 21°C for this time of
year. Heat wave conditions were also recorded
in Alaska recently,
with temperatures
as high as 96°F (36°C).
On June 19, 2013, NASA captured this image of smoke from wildfires burning in western Alaska. The smoke was moving west over Norton Sound. (The center of the image is roughly 163° West and 62° North.) Red outlines indicate hot spots with unusually warm surface temperatures associated with fire.

Wildfires in the North threaten to cause large emissions of greenhouse gases and soot, which can settle on snow and ice in the Arctic and the Himalayan Plateau, with the resulting albedo changes causing a lot more sunlight to be absorbed, instead of reflected as was the case earlier. This in turn adds to the problem. Additionally, rising temperatures in the Arctic threaten to cause release of huge amounts of methane from sediments below the Arctic Ocean. This situation threatens to escalate into runway global warming in a matter of years, as illustrated by the image below.

In
conclusion, the risk is unacceptable and calls for a comprehensive
and effective action plan that executes multiple lines of action in
parallel, such as the 3-part Climate Action Plan below. Part 1 calls
for a sustainable economy, i.e. dramatic reductions of pollutants on
land, in oceans and in the atmosphere. Part 2 calls for heat
management. Part 3 calls for methane management and further measures.
The
Climate Action Plan set out in above diagram can be initiated
immediately in any country, without the need for an international
agreement to be reached first. This can avoid delays associated with
complicated negotiations and on-going verification of implementation
and progress in other nations.
In nations with both federal and state governments, such as the United States of America, the Climate Action Plan could be implemented as follows:
In nations with both federal and state governments, such as the United States of America, the Climate Action Plan could be implemented as follows:
- The President directs federal departments and agencies to reduce their emissions for each type of pollutant annually by a set percentage, say, CO2 and CH4 by 10%, and HFCs, N2O and soot by higher percentages.
- The President demands states to each make the same cuts.
- The President directs the federal Environmental Protection Agency (EPA) to monitor implementation of states and to act step in where a state looks set to fail to miss one or more targets, by imposing (federal) fees on applicable polluting products sold in the respective state, with revenues used for federal benefits.
Such
federal benefits could include building interstate High-Speed Rail
tracks, adaptation and conservation measures, management of national
parks, R&D into batteries, ways to vegetate deserts and other
land use measurements, all at the discretion of the EPA. The fees can
be roughly calculated as the average of fees that other states impose
in successful efforts to meet their targets.
This
way, the decision how to reduce targets is largely delegated to state
level, while states can similarly delegate decisions to local
communities. While feebates,
preferably implemented locally, are recommended as the most effective
way to reach targets, each state and even each local community can
largely decide how to implement things, provided that each of the
targets are reached.
Similar
targets could be adopted elsewhere in the world, and each nation
could similarly delegate responsibilities to local communities.
Additionally, it makes sense to agree internationally to impose extra
fees on international commercial aviation, with revenues used to
develop ways to cool the Arctic.
