The Anthropocene: our place in Earth’s history

The Anthropocene – the concept that the Earth’s surface geological processes are now human-dominated – is often considered to be more or less synonymous with climate change.  Today, however, climate change is only one component – relatively minor, still – of the changes to the Earth system invoked to justify the Anthropocene.  However, the last couple of centuries have seen large and accelerating changes in some of the key factors that drive global climate, and it is widely agreed among scientists that climate change has begun.  In future decades, centuries and millennia, climate change seems likely to emerge as a central driver of changing geological process on Earth. The...

Challenged by carbon: rocks and climate change

You can’t argue with a rock.  So ideally we would now be on a field trip.  Instead, I offer you a short film made in the field by the Science Museum to accompany a lump of Hertfordshire Puddingstone that is featured in the Atmosphere Gallery, first opened in 2010.   Thanks to geology, the scientific case for human-induced climate change has recently become significantly more plausible.  New observational science based on cores taken from deep beneath the floor of the oceans offers crucial support and control for the computer-based forecasts of those creating models of future climate change.  Thanks to the work of the late...
