It appears that this year's 'Summer' Bank Holiday in England and Wales will be the coldest on record, with temperatures as low as 11༠C and torrential rain (https://metro.co.uk/2020/08/28/uk-set-coldest-august-bank-holiday-record-13189999/). Some people still seem to expect different from 'global warming'. The 'greenhouse gases' (largely carbon dioxide and methane) do prevent some solar radiation being reflected back into space, producing an overall increase in the temperature of the planet's atmosphere. This, however, disrupts the weather patterns (produced by flows of air and sea currents) in a rather 'patchy' way. Currently, we are being exposed to relatively cold but water-impregnated (the heavy rain further cools things down) air flows. Consequently, our 'weather' (essentially a local event) is very different from the 'normal' high summer conditions we have come to expect.
