Although APS plans to
reduce its coal burn from the current 35 % to 17 %
by 2029,
by increasing its natural gas burn from 19 % to 35 %, it will actually increase its greenhouse gas

Thawing permafrost also delivers organic - rich soils to lake bottoms, where decomposition in the absence of oxygen releases additional methane.116 Extensive wildfires also release
carbon that contributes to climate
warming.107, 117,118 The capacity of the Yukon River Basin in Alaska and adjacent Canada to store
carbon has been substantially weakened since the 1960s
by the combination of
warming and thawing of permafrost and
by increased wildfire.119 Expansion of tall shrubs and trees into tundra makes the surface darker and rougher, increasing absorption of the sun's energy and further contributing to
warming.120 This
warming is likely stronger than the potential cooling effects of increased
carbon dioxide uptake associated with tree and shrub expansion.121 The shorter snow - covered seasons in Alaska further increase energy absorption
by the land surface, an effect only slightly offset
by the
reduced energy absorption of highly reflective post-fire snow - covered landscapes.121 This spectrum of changes in Alaskan and other high - latitude terrestrial ecosystems jeopardizes efforts
by society to use ecosystem
carbon management to offset fossil fuel
emissions.94, 95,96
Both wetland drying and the increased frequency of
warm dry summers and associated thunderstorms have led to more large fires in the last ten years than in any decade since record - keeping began in the 1940s.9 In Alaskan tundra, which was too cold and wet to support extensive fires for approximately the last 5,000 years, 105 a single large fire in 2007 released as much
carbon to the atmosphere as had been absorbed
by the entire circumpolar Arctic tundra during the previous quarter - century.106 Even if climate
warming were curtailed
by reducing heat - trapping gas (also known as greenhouse gas)
emissions (as in the B1 scenario), the annual area burned in Alaska is projected to double
by mid-century and to triple
by the end of the century, 107 thus fostering increased
emissions of heat - trapping gases, higher temperatures, and increased fires.
By reducing black
carbon emissions, «we'd get a much more rapid response in the
warming than
reducing something like CO2,» says Quinn.
He wrote a well - reviewed book called «The Climate Fix: What Scientists and Politicians Won't Tell You About Global
Warming,» in which he presents measured skepticism of climate - change orthodoxy — for example, he believes the role of
carbon emissions from human industry is greatly exaggerated
by politicized science, but he doesn't think human
carbon emissions are irrelevant, and is not implacably hostile to the goal of
reducing them.
To meet the goal of the Paris Agreement, which aims to limit

Assuming the IPCC's value for climate sensitivity (i.e. disregarding the recent scientific literature) and completely stopping all
carbon dioxide
emissions in the U.S. between now and the year 2050 and keeping them at zero, will only
reduce the amount of global
warming by just over a tenth of a degree (out of a total projected rise of 2.619 °C between 2010 and 2100).
The ethical basis for why national INDCs should specify; (a) the number of tons of ghg

by the nation in determining the fairness of its INDC, and (d) for Annex 1 nations,
emissions reductions that will be achieved
by the INDC from 1990, a common baseline year.
By then not only climate scientists, but I would think a large part of the global population will be fully aware of the dangerous consequences of global

This is set to rise steadily higher — yet it is being imposed for only one reason: the widespread conviction, which is shared

warming is certain soon to accelerate, with truly catastrophic consequences
by the end of the century — when temperatures could be up to five degrees higher.
Too bad, as the New York Times point out, that even though natural gas does have a far less impact on global
warming than does coal, if we're going to

Forcing
by non-CO2
emissions includes a component driven
by the response of the
carbon - cycle to temperature changes induced

warming (Arora et al. 2013; Collins et al. 2013b).

carbon emissions, seen
by scientists as a key cause of global
warming,
by reducing the need for trucks to deliver vegetables from long distances.
While many scientists and climate change activists hailed December's Paris agreement as a historic step forward for international efforts to limit global
warming, the landmark accord rests on a highly dubious assumption: to achieve the goal of limiting the rise in global average temperature to less than 2 °C (much less the more ambitious goal of 1.5 °C), we don't just need to
reduce emissions of
carbon dioxide to essentially zero
by the end of this century.
