It’s not climate change, it’s ocean change!

  1. Well put John… I’ve often thought about the warming of oceans, but from the high specific heat value of water angle. Not actively studying though, it’s been on my mind more that anything. lol
    I agree that we need to being making changes now – the longer we put off changes in our practices, the higher the cost (both economically and ecologically). What I’ve noticed is that there many options already existing that don’t need radically technological advancements to help us reduce our emissions while continuing (or improving) our standards of living – it’s a change in behaviour and infrastructure that could make the biggest and quickest changes.

  2. It looks like a hockey stick to me. I drew up my own curve last summer from NOAA Ocean heat data and the hockey stick fits well.
    The cooling trend seen in the 1960s led some of us to build passive solar homes and insulate in anticipation of bigger heating bills in 1970s. Though that is always a useful even with the warming trend.
    Ocean heat is a major cause of ice melt for ice sheets and for tidewater glaciers.
    I did some calculations from water masses in Glacier Bay and was able to show the melted-ice contribution from seasonal temperature and salinity data. Freshwater ice at zero degrees gives up its latent heat and reduces the salinity and temperature of the fjord. This gives a handle on the quantities involved. It assumes glacial input is mainly ice ignoring the under ice meltwater from higher up the glacier. However since it all started out as ice it gives a good ice of glacial ice contribution to the nearby ocean.

    I wonder if anyone has done the same around other tidewater glaciers in Greenland, Chile or Antarctica?
