"The twenty-seven Conferences so far have had no effect on total global emissions. "

"The forthcoming 28th session (COP28) of the Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC) ... will convene from 30 November to 12 December in the United Arab Emirates. The ‘Parties’ are UN member states plus some observers. The last one, COP27 at Sharm el Sheik in Egypt, had 12,000 delegates from over 200 countries.
    "There has been one every year since except for 2020. All 27 have warned about the increasingly noxious state of the atmosphere and declaring that something must be done about it before it’s too late. ...
    "The CO2 content of the atmosphere has been measured since 1957 and has risen steadily every year. The twenty-seven Conferences so far have had no effect on total global emissions. Nations have realised their people’s need for electricity had to come first. The cheapest and quickest way to provide that is by way of fossil-fuelled power stations.
    "Leaders of nations may also have wondered at the increasingly manic shouts of: ‘global boiling’; ‘July the warmest in human civilisation’s history’; ‘oceansgrowing hotter … triggering global weather disasters … heat searing enough to knock out mobile phones’; ‘daily temperatures hitting a 100,000 year high’; ‘the September data shows … the planet’s temperature reached its warmest level in modern records and probably in thousands of years.’
    "Advisers to leaders of nations may have pointed out that we have only been measuring daily world-wide temperatures for about 140 years. NASA makes it quite clear that ‘before 1880 there just wasn’t enough data to make accurate calculations.’ The last ice age ended about 10,000 years ago; the advisors may have advised that it would therefore seem reasonable to expect that records will be broken, will continue to be broken, and may or may not have anything to do with global warming.
    "There has curiously been very little comment about the willingness of the UN to go on having Conferences calling for actions that don’t [and shouldn't] happen."
