Acid Oceans: The Gravest and Most Immediate Planetary Threat Yet?
April 24, 2009 by Ocean Doctor · Leave a Comment
Ocean acidification may present one of the gravest threats to our planet’s ecosystems and yet it is also one of the least publicized aspects of the global climate change issue. Acidification is occurring very rapidly, causing unprecedented changes to the chemistry of the oceans. It’s been estimated that roughly half of human-produced CO2 emissions over the past two centuries (since the beginning of the industrial age) have been absorbed by the oceans, leading to a drop in ocean surface pH of nearly 0.1 units (on the logarithmic pH scale).

We're working around the clock to help our Cuban colleagues prepare for the possibility of an oil spill from the BP Deepwater Horizon spill in the Gulf of Mexico. None of this work was anticipated, so we need your help to fund our efforts and ensure that we're prepared in advance should the worst occur.
