• 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?

Over the past two decades, researchers have shown that ocean acidification is increasing as humans have added more carbon dioxide (CO2) to the atmosphere. A panel of scientists reports a summary of outcomes, in which they connect the impacts on ecosystems and socio-economic consequences with levels of confidence that have implications for policy.

This new publication is based on the research presented at The Third Symposium on the Ocean in a High-CO2 World, where 540 experts from 37 countries gathered in Monterey, California, in September 2012. The outcomes described here are informed by that discussion and the latest peer-reviewed research. They illustrate for policymakers what the implications could be of ocean acidification in the future – both with and without any action taken today.


Download the summary herePDF (pdf, 4.9 MB), as well as the infographics that illustrate the problems that ecosystems -- and humans -- face as ocean acidification increases over the next century. The summary addresses outcomes based on whether humans continue to emit carbon dioxide at current rates to the atmosphere, or what could happen if policymakers take action to mitigate these emissions. This publication is co-sponsored by IGBP, SCOR and IOC-UNESCO.
