Also included was the need to enhance local and regional management practices to identify and reduce the primary drivers of high - carbon coastal system degradation, as well as the requirement to enhance international recognition of coastal carbon ecosystems.

The capture and release of carbon dioxide is difficult to study in coastal systems because of their diverse and variable nature.

The potential of coastal ocean alkalinization (COA), a carbon dioxide removal (CDR) climate engineering strategy that chemically increases ocean carbon uptake and storage, is investigated with an Earth system model of intermediate complexity.

I reached out to Pierrehumbert because he is one of many authors of «Consequences of twenty - first - century policy for multi-millennial climate and sea - level change,» an important new Nature Climate Change analysis reinforcing past work showing a very, very, very long impact (tens of millenniums) on the Earth system — climatic, coastal and otherwise — from the carbon dioxide buildup driven by the conversion, in our lifetimes, of vast amounts of fossil fuels into useful energy.

David, I havent been keeping up with all the PETM research, but I do recall that individual plankton recovered from Bass River, New Jersey show a single step CIE. Due to the high sedimentation rate of coastal fluvial systems, Bass River sediments are consistent with a much shorter duration of organic carbon release during the PETM (estimated as less than 500 years).

Using the forest carbon sequestration system used so much recently, one or two mechanisms exist to pay governments or landowners for coastal area conservation.

This created a qualitative transformation in Homo sapiens» impact on earth system trends: levels of carbon dioxide, nitrous oxide, methane, stratospheric ozone, surface ocean temperature, ocean acidification, marine fish capture, coastal nitrogen, tropical forest depletion, land domestication and terrestrial biosphere degradation.

Developing an Infrastructure Fund for the Planet explored how ecosystem service payments and markets in carbon, water and biodiversity are quickly becoming a key solution to the urgent environmental problems of climate change, fresh water pollution, biodiversity loss, soil erosion, and destruction of our coastal and marine systems.

This new concept of anthropogenic impacts on seawater pH formulated here accommodates the broad range of mechanisms involved in the anthropogenic forcing of pH in coastal ecosystems, including changes in land use, nutrient inputs, ecosystem structure and net metabolism, and emissions of gases to the atmosphere affecting the carbon system and associated pH. The new paradigm is applicable across marine systems, from open - ocean and ocean - dominated coastal systems, where OA by anthropogenic CO2 is the dominant mechanism of anthropogenic impacts on marine pH, to coastal ecosystems where a range of natural and anthropogenic processes may operate to affect pH.

Calculations to resolve the anthropogenic component of CO2 are remarkably difficult for the coastal ocean, where the assumptions of the various methods (Sabine and Tanhua 2010) are not met, thereby precluding a direct calculation of the effect of anthropogenic CO2 on observed trends in coastal pH. Calculations based on mixing between an open - ocean end - member displaying the trajectories predicted from OA and the freshwater end - member are also unreliable because pH and the carbon system do not necessarily behave conservatively within the coastal zone and because the freshwater end - member may also shift into the future.
