Collectively, we hypothesize that the high warming scenario will degrade 9 15% of the top 3 metres of permafrost by 2040, increasing to 47 61% by 2100 and 67 79% by 2300 (these ranges are the 95% confidence intervals around the group's mean estimate).
Aluminum has the highest global warming potential, whereas copper has the highest material footprint.
Due to the high energy input needed for primary aluminum production, it comes as no surprise that this process also has the highest global warming potential.
About 11% of anthropogenic methane emissions come from rice paddies (IPCC 2013 ), and among the major cereals, rice has the highest global warming potential (GWP) due to high methane emissions (Linquist et al. 2012).
The sunrise splinters through the high trees, warming our damp bodies and setting the stones aglow.
An organic carbon decomposition model, calibrated with laboratory incubations, indicates a greater production rate of CO2-C equivalents from waterlogged (compared to drained) permafrost soils, when the higher global warming potential of methane is factored in.
Less permafrost carbon was mineralized under anoxic conditions but more CO2 carbon equivalents (CO2 Ce) were formed than under oxic conditions when the higher global warming potential (GWP) of CH4 is taken into account8.
However, because of the high global warming potential of methane (CH4, the major component of NG), climate benefits from NG use depend on system leakage rates.
