In fact, the
mitigation pledges collected under the ongoing Cancun Agreements, conceived during the 2010 climate talks, would lead to global average temperature rise

In 2014 alone, reports from the Intergovernmental Panel on Climate Change, the International Energy Agency, the UN Sustainable Solutions Network and the Global Commission on the Economy and Climate argued for a doubling or trebling

At a plausible GHG
emissions price
of $ 50 / t CO2eq under a future US carbon
mitigation policy, such co-production systems competing as power suppliers would be able to provide low - GHG - emitting synthetic fuels at the same unit cost as for coal synfuels characterized by ten times the GHG
emission rate that are produced in plants having three times the synfuel output capacity and
requiring twice the total capital investment.
Given that this is only one
of the seven major interactive feedbacks, and that it is evidently accelerating apace, I'm forced to the unwelcome conclusion that both Carbon Recovery and Albedo Restoration modes
of geoengineering are now inevitably
required alongside stringent
Emissions Control in a Troika
mitigation strategy.
With only two scheduled days
of negotiations left, there has been no measurable movement on
emissions reductions targets or finance for climate adaptation and
mitigation of the scale the urgent situations
requires.
To achieve an absolute reduction in
emissions from the industry sector will
require a broad set
of mitigation options going beyond current practices.
So we had a look at that and worked on it and many things we have done have followed from that, both on the impact side,
mitigation,
emission reduction, modelling, climate finance, a lot
of the central organising principle has become about how to take the steps
required to enable countries to deal sustainably with the challenges
of meeting the 1.5 C limit.
In the context
of mitigation, the discount rate matters because it could be argued that even though delayed
mitigation is more costly than cutting
emissions now (because steeper cuts are
required), those delayed (greater) expenses are not «worth as much» as today's costs because they are discounted.
We can clarify the nature
of emission trajectories further by picking a carbon budget and examining the
required trajectories as a function
of the time when we commence
mitigation.
If nations fail to base their climate change policies on what equity, ethics, and justice
require of them on
mitigation of their greenhouse gas
emissions and funding for adaptation, losses, and damages, then the global response to climate change will not likely be ambitious enough to avoid catastrophic climate impacts while deepening existing injustices in the world.
Bolivia draws strongly and explicitly upon ethical justifications for
requiring deep cuts in national ghg
emissions by other nations, together with financial contributions and holistic
mitigation and adaptation measures, capable
of both reducing poverty and vulnerability to climate change yet has not identified an equity framework that could be applied at the global scale.
But along with
emissions - reduction
mitigation to reduce the rate and magnitude
of climate change as expeditiously as possible, a comprehensive risk - management climate policy will necessarily
require a strategic and multifaceted effort at preparedness to limit vulnerabilities and increase resilience to impacts that can't be avoided.
Concentrating on the result
of the equation can be useful to understand what would be
required for adapting, but our
mitigation efforts should be focused on controlling
emissions and not degrees celsius
While the introduction
of a tax - based
mitigation system would take the world significantly forward, the Review has come to the view that only an international agreement that explicitly distributes the abatement burden across countries by allocating internationally tradable
emissions entitlements has any chance
of achieving the depth, speed and breadth
of action that is now
required in all major emitters, including developing countries.
If we don't want to screw up our climate, it is time to put the fruitless debates on climate - engineering techniques to rest, and focus on the only real solution, which is a tremendous challenge
requiring all our intellectual resources: The
mitigation of greenhouse gas
emissions.
Ultimately, from the perspective
of policy makers and the general public, the impacts
of climate change and the
required mitigation and adaptation efforts are largely the same in a world
of 2 or 4 C per doubling
of CO2 concentrations where carbon dioxide
emissions are rising quickly.
I would also very much like to see some costings
of the
emissions pathway being championed by the Worldwatch Institute — costings both
of the climate change impacts which would still occur, and
of the efforts
required to reduce
emissions to the proposed degree — because I think this particular
mitigation scenario can be as valuable in getting us on track as has been James Hansen's promotion
of 350ppm as a target.
(b) that the cost
of emissions reductions at the
required scale is likely to be manageable (1 %
of global annual GDP to be invested in
mitigation according to some economists), provided that meaningful action is taken immediately; and
Mitigation scenarios (also known as climate intervention or climate policy scenarios) are defined in the TAR (Morita et al., 2001), as scenarios that «(1) include explicit policies and / or measures, the primary goal
of which is to reduce GHG
emissions (e.g., carbon taxes) and / or (2) mention no climate policies and / or measures, but assume temporal changes in GHG

of demand established by an
emissions trading scheme.
