evidence: I am wondering which official figures Lord Lawson speaks about since the year with the hottest global mean temperature is currently 2016, the second hottest is 2015, and third is 2014 according to data sets from NASA, the Climatic Research Unit, and the National Oceanic and Atmospheric Administration. In fact, according to these data sets the last 10 years saw some of the most rapid global mean temperature increases in observed history. Below is a figure that shows the data from NASA. [...] This statement is not true. The official figures do not show that the global mean temperature "has slightly declined". In fact they show the opposite – global mean temperature has increased during the past 10 years. The last 3 years were warmer than the previous 7 and indeed were the warmest in record, and this year is also shaping up to be nearly as warm (probably not quite as warm as last year since the influence of the El Nino has passed, but still a very warm year). This is very clearly seen in the Met Office dataset, which happens to be shown prominently on the websites for Lord Lawson’s organisations, the Global Warming Policy Foundation and the Global Warming Policy Forum – so his claim is contradicted by information that headlines his own websites.
