Aging weather stations contribute to high temperature records: ‘New paper finds that aging weather stations record much higher daytime temperatures, 1.63°C higher than new stations’
'A paper published in the International Journal of Climatology finds that aging of the solar radiation screens on weather stations is causing a large positive bias in measured temperatures of 1.63°C, which by way of comparison is more than twice the global warming of 0.7°C recorded since the end of the Little Ice Age in 1850.'
