Sir, – Last week it was reported that 3,318 places in the US had recorded their lowest temperatures for this time of year since records began. Similar record cold was experienced by places in every province of Canada. So cold has the Russian winter been that Moscow had its deepest snowfall in 134 years of observations.
Britain had its fifth freezing winter in a row, the Central England Temperature record according to climate science blog Watts Up With That shows that in this century, average winter temperatures have dropped by 1.45 degrees Celsius, more than twice as much as their rise between 1850 and 1999, and twice as much as the entire net rise in global temperatures recorded in the 20th century.
Perhaps we need at least 400 ppm of CO2 to keep us warm in the coming years! – Yours, etc,
