Scientists record rapid carbon loss from warming peatlands

(DOE/Oak Ridge National Laboratory) Scientists at the Department of Energy’s Oak Ridge National Laboratory have demonstrated a direct relationship between climate warming and carbon loss in a peatland ecosystem. Their study published in AGU Advances provides a glimpse of potential futures where significant stores of carbon in peat bogs could be released into the atmosphere as greenhouse gases.

Solving the jigsaw puzzle of regional carbon budgets

(Science China Press) Ciais and colleagues obtained the first bottom-up global land carbon budget from the sum of regional estimates, combining inventories with lateral transfers from the trade of wood and food products and the export of dissolved carbon by rivers to the oceans. Carbon being moved away from ecosystems by lateral fluxes and emitted by fires and as reduced compounds is a large fraction of primary production inputs, implying a smaller CO2 emission from soil microbial decomposition.

Low-severity fires enhance long-term carbon retention of peatlands

High-intensity fires can destroy marshy peatlands and cause them to emit huge amounts of their stored carbon into the atmosphere as greenhouse gases, but a new study finds low-severity fires spark the opposite outcome. By creating a decay-inhibiting crust on clumps of moist soil particles within the peatland, the smaller surface fires help protect the stored carbon and enhance peatlands’ long-term storage of it, even during times of extreme drought.

Sugar brings a lot of carbon dioxide into the deeper sea

The oceans are a very important reservoir for carbon in the system of the earth. However, many aspects of the marine carbon cycle are still unknown. Scientists have now found that sugar plays an important role in this process. At the same time, the sweet energy source is important for the ecosystem of the oceans.

Analysis: Why coal use must plummet this decade to keep global warming below 1.5C – Carbon Brief

The next 10 years are crucial for tackling climate change, with widespread recognition that CO2 emissions must fall 45% by 2030 to keep global warming below 1.5C. Yet global emissions are expected to continue rising, despite the pledges made by…
