global carbon emissions could be cut by one gigatonne per year (3 % of
global emissions) in less than five years if other countries
followed the same strategy.
Our ensemble fire weather season length metric captured important wildfire events throughout Eurasia such as the Indonesian fires of 1997 — 98 where peat fires,
following an El Niño - induced drought, released
carbon equivalent to 13 — 40 % of the
global fossil fuel
emissions from only 1.4 % of the
global vegetated land area (Fig. 4, 1997 — 1998) 46 and the heatwave over Western Russia in 2010 (Fig. 4, 2010) that led to its worst fire season in recorded history and triggered extreme air pollution in Moscow51.

carbon emission pathway humans
follow, which determines the sustained
global warming that can be maintained for centuries to millennia.
Finally, to revisit the question originally posed @ 203: Assuming the IEO2011 Reference case of «1 trillion metric tons of additional cumulative energy - related
carbon dioxide
emissions between 2009 and 2035», and given that this case equates to
following RCP8.5 until 2035 as previously demonstrated @ 408, what increase in average
global surface temperature relative to pre-industrial would result by 2035?

follows this scaling in the future, for illustrative purposes.
As a number of scientific articles have shown, most recently by Kevin Anderson and Alice Bows in the Journal of the Royal Society, limiting the world to 2 °C warming most likely requires peaking total
global carbon emissions in the next 5 - 10 years
followed by immediate reductions to near - zero by 2050 (see Anderson and Bows
emission trajectory options here, via David Roberts, and by David Hone here).
And (2) with regard to its main rationale,
carbon emissions cause warming, the vector of causation is backwards: atmospheric CO2 concentration
follows global warming, empirically and theoretically, while human
emissions are lost in the noise.
However, if high - emitting nations take the «equity» and «fairness» requirement seriously, they will need to not only reduce ghg
emissions at very, very rapid rates, a conclusion that
follows from the steepness of the remaining budget curves alone, but also they will have to reduce their ghg
emissions much faster than poor developing nations and faster than the
global reductions curves entailed only by the need to stay within a
carbon budget.
For example, the management of any
global biodiversity conservation goal through the mitigation hierarchy could
follow a similar framework to the United Nations» management of
carbon emissions, with nation states setting their own national goals and targets that then sum to achieve overarching planetary goals.

In late 2016,
following the November elections, Anne Lee and a cohort of students in Sammamish, WA realized that the incoming Trump administration was unlikely to
