The UN’s Intergovernmental Panel on Climate Change is accused of alarmism. I should hope that alarm is what it has generated. The latest heat re old is a report of 48.8C from Italy. Fires in California, Algeria, Greece maybe partially due to poor management over the last 100 years (possibly a result of population growth in these areas), but they. have been exacerbated by the record high temperatures.
Another, contradictory comment is one about the increase in eco-refugees. Millions of people have been displaced due to climate change, and this is likely to increase exponentially over the next decades regardless of COP26. Sea level rising is a process that takes years to initiate and years to reverse (if possible?). The warming of the oceans has taken place and water will this expand. This combined with the melting of ice on Antarcticas and Greenland will raise sea level over the next century. Pacific Islands and parts of the Maldives amongst others will be gradually swamped. Plans are already being made for a new Thames Barrier, managed retreat is a reality of coastline management in many parts of the UK (and the Netherlands). Signs of stress are appearing in coral reefs which at present protect coastlines from erosion by storms.
And the decline in insects in Europe is marked. I am not sure if this is related to climate change but something is affecting the ecosystem. My garden should be a butterfly paradise with lots of different insect friendly plants in flower. Apart from a few bees, small white butterflies and occasional visits from other species it is fairly lifeless. My trip down the motorway did not result in an insect graveyard on the front as it would have done 30 years ago.
