Report bullet points:"Urgent need to increase carbon sequestration in land and
forests. With only 200GtCO2 left until the global carbon budget for 1.5°C is
blown, it is highly likely that therewill be a need to increase removals of CO2
from the atmosphere to limit warmingto 1.5°C or even 2°C. This could be done
through halting deforestation and forestdegradation, restoring degraded
forests, and reforesting previously deforested land.These actions would go some
way to restoring historically depleted land carbon stocks."
GR Why isn't there also an urgent need to increase marine carbon sequestration,
which = 70% of the Earth's surface, half the annual C cycle, and the vast
majority of C stored on the Earth surface. Ocean C = 16 X land biomass + soil
C!? How do we manage atmospheric C by ignoring the ocean?
"Forests and land do not offset fossil fuel emissions. Plants, trees and soils
removeCO2 from the atmosphere, but this does not offset the release of CO2 when
fossil fuelsare burnt. Increasing carbon sequestration in plants, trees and
soils repays the landcarbon debt accumulated from historical land use change,
but does not compensateon-going emissions. To mitigate climate change we must
reduce emissions from thefossil fuel and the land sector, not offset one
against the other."
GR - Forests and land do offset about 1/4 - 1/3 of fossil fuel emissions, as
does the ocean. Great if we can repay the land C debt (how big relative to
excess CO2?) AND satisfy growing land based food, fiber and fuel production.
Feasibility? Otherwise how/why can we ignore C management potential and food,
fiber and fuel production in the ocean?

(2016): Report of the seminar 'Negative Emissions' facilitated by Fern.
Brussels.
http://www.fern.org/sites/fern.org/files/Negative%20emissions%20seminar.pdf
This seminar held in May 2016 brought key scientists together with
environmental, development and human rights NGOs to understand the Paris
Agreement’s implications for forests and land use. --
