York House,
Richmond Road,


Once we can understand why the Earth’s surface is the temperature it is, then we can begin to understand the physics which underlies climate change. The temperature of the air above the land surface of the Earth is a topic of great current interest. In this talk Michael will explain (a) how it is measured and (b) how we can understand why Earth has the climate it has. Finally he will discuss the reasons to be concerned about recent changes in the Earth’s surface temperature. He asks us to ‘Please come along with questions of all kinds!’

Michael de Podesta is a scientist at the UK’s National Physical Laboratory. He mainly works on measurement problems related to temperature, but is interested in all aspects of physics. Together with colleagues, he has made the most accurate temperature measurements ever, detailing the errors in all the other thermometers on Earth!
