What is #bluecarbon?
Vegetated coastal ecosystems are precious for carbon uptake and storage, and for storm and sea level rise protection, water quality, biodiversity and fisheries.

#Clouds enhance the cooling effect of aerosols. Clouds amplify global warming. Their climate effect is a main source of uncertainty for the magnitude of future warming.
They focus intense research activities through observations, process and model studies.

Ocean #deoxygenation is observed and will continue in a warming world. It is one of the 5 primary drivers of marine ecosystem change, with warming, acidification, nitrate content and net primary production change.

Today's word is relevant to many aspects of the climate change context, incl. @IPCC_CH approval sessions.
#Equanimity, a calm state of mind that means that you do not become angry or upset, especially in difficult situations (Source, Oxford dictionary).
#1day1wordforclimate
#Adaptation to climate change can take various forms, face soft or hard limits, while maladaptive actions can unintendedly increase adverse climate-related risks.

Public #acceptability can shape, enable or inhibit responses to climate change.
It depends on the perceived fairness of the distribution of the consequences of policies and measures, and of decision procedures.
