Our next meeting
Our last meeting:
Prof Joanna Haigh CBE, FRS
Department of Physics, Imperial College London
The world is warming at a rate faster that has ever been observed in the past. Overwhelmingly scientists are of the opinion that this is largely due to the effect of gases released into the atmosphere by human activities. How can we be sure that this is the case? Does it matter? What can we say about the future?
This talk will look at the scientific evidence for climate change in the context of natural variations and it will discuss how increasing concentrations of “greenhouse gases” (GHGs) create an imbalance in the Earth’s energy budget with impacts on temperature, sea level and weather patterns.
We will see how basic physics can be used to construct the computer models which are employed to investigate climate processes and look at potential future impacts across the world of increasing GHGs.
We will go on to consider what needs to be done to reduce GHG emissions in order for the world to avoid dangerous levels of warming, and where we are heading following the United Nations climate change agreements.
Joanna Haigh is Emeritus Professor of Atmospheric Physics at Imperial College London. Formerly co-Director of the Grantham Institute on Climate Change and Head of Imperial’s Physics Department, she has published widely on atmospheric radiative transfer. Her work on the impacts of solar activity on climate has been particularly influential. Her contributions to the international scientific community include through the Intergovernmental Panel on Climate Change, the US National Academies of Science and the European Space Agency. She is a Fellow of the Royal Society, an Honorary Fellow of Somerville College, Oxford, and of the Royal Meteorological Society, of which she is also a past-President. She was appointed CBE for services to physics in 2013.
