Nature Climate Change highlights Susan Natali's Large loss of CO2 in winter observed across the northern permafrost region, observing:
Warming in the Arctic is causing soils to decompose more rapidly, even during winter. Now, estimates of winter carbon dioxide loss indicate that it can offset carbon gains during the growing season, meaning that the region is a source of carbon.
We need another positive feedback like we need a hole in the head. Outcomes like this increase the weight of mitigation lifts we are currently failing to perform.
Geophysical Research Letters notes an article by D. Saint?Martin, Fast?Forward to Perturbed Equilibrium Climate, remarking:
The Earth system responds on a range of timescales to a change in radiative forcing, and full equilibration takes centuries to millennia in many models. In their recent paper, [D.Saint-Martin et al] propose a technique for reaching a faster equilibrium temperature response to alternative CO2 concentration levels by briefly overshooting the desired concentration level to warm the deep ocean faster than a conventional step?change experiment. Understanding how these timescales interact is essential for better representing the relationship between transient climate change and the warming which should be expected as greenhouse gas concentrations stabilize. But, the technique also raises new possibilities about how Earth System Models could be developed, and whether we could gain the capacity to spin up alternative model configurations such as perturbed parameter simulations or alternative control states to explore historical forcing uncertainty.
Adjusting input variables to dairy cattle so as to optimize for maximized milk output and minimized CO2 hoofprint is explored by Brandt et al with their Intensification of dairy production can increase the GHG mitigation potential of the land use sector in East Africa. The authors find that— according to their results— there is potential to significantly expand dairy production while distinctly shrinking both CO2 intensity and (less dramatically) overall emissions from this sector, while also reducing loss of forest productivity. The devil may be in the details and the need to attend to those; the authors note the potential for problems if inputs are not scrupulously sourced.
