In recent years the issue of whether human activity is causing dangerous changes to the global atmosphere has been controversial despite the sequence of reports of the scientific consensus in the UN’s IPCC. The eight indicators in the above diagram for 2017, capture the worrying trends. Vested interests on both sides of the argument claim conspiratorial motives and ‘confirmation bias’ behind the views of their opponents. Here is one view from the BBC which relates to the likely fact that 2014 was the hottest year on record globally and in the UK. And here is one update for 2017. And here another update Sept 2017. This post offers a view from the World Bank on climate change. And here is George Monbiot’s biting critique of in March 2015 of 23 years of wasted UN deliberations on climate change. Just prior to COP21 this report suggests the the one degree Celsius increase in global warming above the 1800-1890 average is about to be reached.
