 lyell.jpgCharles Lyell’s Principles of Geology was published between 1830-1833, and introduced the famous maxim, ‘the present is the key to the past’. Bruce Levell, Chief Geologist at Shell, explains the relevance of this principle to the oil and gas industry today, and why it might be hindering, rather than helping the search for energy resources.

One of the biggest consequences of our use of fossil fuels is its effect on sea level, which is continuing to rise. Is sea level rise natural, or are humans playing a part? And how can geologists help protect our coastlines? Lynne Frostick, Professor of Geography at the University of Hull and Geological Society President, explains what rising tides mean for our future, and how an understanding of our geological past can help us prepare for the future.
