climate and comms

   The oceans have acted as ‘airbags’ in the slow motion car crash that is climate change.    They have absorbed much of the impact and protected us humans from immediate danger - apart from a 'little' whiplash i.e.  heatwaves, floods, droughts and storms. About 30% of CO2 emissions since the beginning of the industrial revolution have been absorbed by the oceans.   So, humans on land have been spared the worst of the impact of atmospheric heating (caused by increased CO2 and other GHG concentrations) that would have otherwise taken place did we not have the oceans.     But this has come at a huge cost : (1)      increased acidification of the ocean (pH has gone from 8.3 to 8.2) it's logarithmic - so actually a 30% increase in acidity ,   and : (2)    Increased temperature of the oceans – especially in the top layer ( up to 700m depth ) – since the 1970’s the oceans have trapped up to 90% of all excess heat ener...
