• China’s emissions glimpsing the peak


    China recently announced its intention to peak its carbon-dioxide emissions. How soon could the emissions peak and at what absolute value? Libo Wu explores.
  • The greening of the Southern Hemisphere


    The 2010-2011 La Niña weather event brought lush vegetation to vast semi-arid regions in the Southern Hemisphere and altered the delicate balance of the global carbon sinks. Owen Gaffney explores how La Niña might change in the future and what that might imply.

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.
