I'm not sure which is the more sad:

1. The change to our weather to two+ seasons, summer and autumn with a very rapid, short spring. The loss of so much of what makes us us (snow, snowyness, winter, cold NWlies, sea ice around Iceland and in the Baltic, cool summers, cold winters, cold springs). Globally the loss of huge forests, the warming of oceans and the changes to fisheries, searing hot and prolonged summers,

2. Or the collective complacency and shoulder shrugging of humanity about what all the above means.

Still some at Aonach Beag apparently.

  It has been measured for 300 years but it is a pity the records are not longer as would it have been there in the Medieval warm period?

Did you read the Tweet? He says that Aonach Beag is about to melt.
