• Using the Planet


    Even before the advent of agriculture, Homo sapiens kicked off an entirely new process of planetary change. Earth would never be the same. Instead of mere centuries, Erle C Ellis advances a broader view of the Anthropocene, over many millennia, and what that means for land stewardship.
  • Lessons from a simulated civilisation


    The rise and fall of the ancient Maya has
    intrigued historians and archaeologists for decades. Now, Earth-system scientists are taking a keen interest. Scott Heckbert asks: what role might environmental conditions and trade play in the growth and eventual collapse of a civilisation?

New Google Earth tour: Ocean acidification

Google produced a new Google Earth tour on ocean acidification with partners IGBP and the International Union for Conservation of Nature (IUCN) for the major international conference, the Ocean in a High CO2 World, co-sponsored by IGBP.

A new Google Earth tour explores the phenomenon of ocean acidification and explains why even small changes to ocean chemistry could have profound implications for marine life and future economic activities.

Follow the tour as we fly from the Great Barrier Reef to remote islands in the Arctic and the bubbling seabed off Vesuvius in Italy.

Hear stories of how ocean acidification is already affecting marine life and livelihoods' dependent on a healthy ocean, such as shellfish farming.

This animated tour was first presented at the 3rd Symposium on the Ocean in a High CO2 World in Monterey in September 2012 and was prepared in partnership with Jenifer Austin Foulkes (Google).

Narration, script and production: Dan Laffoley from the International Union for Conservation of Nature (IUCN), Chair of Europe's Ocean Acidification Reference User Group.

Production and script: Owen Gaffney (International Geosphere and Biosphere Programme)

The animated sequence of ocean acidification through to the year 2300 was created using data provided by the Max Planck Institute for Meteorology www.mpimet.mpg.de (courtesy Dr. Tatiana Ilyina) and the visualization tools of the German Climate Computing Center www.dkrz.de (courtesy Dr. Michael Böttinger).
