Review and comments on the BBC Programme, “Operation Iceberg”, first broadcast in October 2012
By Tom Power*
Last year was the centenary of the Titanic disaster and the BBC produced a programme in two parts on the life of ice bergs. As well as the historical content, it was most apt, as the research into global warming since 2000 has thrown new light on the formation of ice bergs an...

Current concerns are focused on the projected magnitude and the rate of warming during the 21st century, which is ascribed to the increase in CO2 concentration in the atmosphere consequent on mankind’s combustion of carbon based fuels. There is a high degree of uncertainty in these projections, related to the expectations for economic growth and ...

Mike Daly explores the implications of the ‘Paris Agreement’ for the future of the hydrocarbon industry.
The “Paris Agreement” of 12 December 2015 has been described as the most ambitious climate agreement to date. It has been widely celebrated and on several levels the agreement is a success. In particular, it marks the first time that both developed and develo...
Palaeoanalogue CIEs and current biosphere & ecological change as guides to the 22nd Century and beyond
A two-day conference held at the Geological Society on 2-3 November 2010.
The biosphere and many of its ecosystems are currently changing due to global warming in an manner unprecedented for many million years. Research shows that abrupt environmental perturbations of the late Palaeoc...
Scientists have come closer to identifying the cause of the Paleocene-Eocene Thermal Maximum (PETM), a period of rapid temperature rise which many believe to be the closest analogue to present day climate change.

For the first time, ancient magma from offshore Norway has been dated, with results suggesting it forced its way between rock layers and triggered the release of large amo...
Sir, David Strachan provides a view of the future, based on peak oil occurring between 2016 and 2037 [1]. Peak oil was previously forecast in 1971 at between 1990 and 2000 [2] and in 1998 at 2008 [3]. Capital investment tends to follow the cyclic variation in commodity prices. This investment cycle coupled with the typical field production profile will inevitability lead to a perception that there...
The November 2009 issue of Geographical Magazine presents a disturbing account of the present status of the Arctic region, mainly the Arctic North, and the impact of global warming there. Most importantly, Arctic Ocean temperatures have increased by about 0.6°C between 1982 and 2009. As a result, there has been a steady decline in the thickness of Arctic ice. For example, the average extent of...
Peter Barrett is Professor of Geology at Victoria University, Wellington and was the founding Director of the Antarctic Research Centre there (1973-2007). He has had a long and distinguished career in unravelling Antarctic geological history, in his early years studying the Gondwana stratigraphy of the Transantarctic Mountains.
A paper, published in Science in 1968 and reported in Time magazine, ...
Dear Editors. I am most concerned by recent articles citing the decline in the teaching of geology and its adverse impact on the profession. Despite essentially leaving the subject after my graduation, I believe that a geological degree gives one a wonderful start to a career.
The profession must reach out beyond the known world of geology. I come from an island where, in my school days, the age...
