World climate at the crossroads – much depends on USA election result

Guardian 26th Oct 2020, Among the myriad reasons world leaders will closely watch the outcome of a fraught US presidential election, the climate crisis looms perhaps largest of all. The international effort to constrain dangerous global heating will hinge, in large part, on which of the dichotomous approaches of Donald Trump or Joe Biden prevails.
On 4 November, the day after the election, the US will exit the Paris climate agreement, a global pact that has wobbled but not collapsed from nearly four years of disparagement and disengagement under Trump.
Biden has vowed to immediately rejoin the Paris deal. The potential of a second Trump term, however, is foreboding for those whose
anxiety has only escalated during the hottest summer ever recorded in the northern hemisphere, with huge wildfires scorching California and swaths of central South America, and extraordinary temperatures baking the Arctic.

Ocean ecosystems – future in doubt

The uncertain future of the oceans, Science Daily October 26, 2020

Source:
Helmholtz Centre for Ocean Research Kiel (GEOMAR)
Summary:
Marine food webs and biogeochemical cycles react very sensitively to the increase in carbon dioxide (CO2) – but the effects are far more complex than previously thought. Data were combined from five large-scale field experiments, which investigated how the carbon cycle within plankton communities reacts to the increase of CO2.
The ocean plays a key role in the current climate change, as it absorbs a considerable part of the atmospheric carbon dioxide emitted by humankind. On the one hand, this slows down the heating of the climate, and on the other hand, the dissolution of CO2 in seawater leads to acidification of the oceans.
This has far-reaching consequences for many marine organisms and thus also for the oceanic carbon cycle. One of the most important mechanisms in this cycle, is called the biological carbon pump. Part of the biomass that phytoplankton forms in the surface ocean through photosynthesis sinks to the depths in the form of small carbonaceous particles. As a result, the carbon is stored for a long time in the deep sea. The ocean thus acts as a carbon sink in the climate system. How strongly this biological pump acts varies greatly from region to region and depends on the composition of species in the ecosystem.

The study, which has now been published in the journal

Nature Climate Change, is one of the most comprehensive studies so far on the effects of ocean acidification on marine ecosystems. Scientists at the GEOMAR Helmholtz Centre for Ocean Research in Kiel have now been able to show for the first time that ocean acidification influences the carbon content of sinking organic material, and thus the biological pump. Surprisingly, the observed changes were highly variable. The carbon content of sinking particles increased or decreased significantly with increasing CO2, depending on the composition of species and the structure of the food web. Since the underlying data cover a wide range of ocean regions, this seems to be a global phenomenon. These findings allow a completely new assessment of the effects of ocean acidification……….https://www.sciencedaily.com/releases/2020/10/201026114214.htm
