Ocean Climate

Ocean acidification is the ongoing decrease in the pH of the Earth‘s oceans, caused by the uptake of carbon dioxide (CO2) from the atmosphere.[2] Seawater is slightly basic (meaning pH > 7), and the process in question is a shift towards pH-neutral conditions rather than a transition to acidic conditions (pH < 7).[3] Ocean alkalinity […]

Peter deMenocal: Climate change might drive human evolution

Climate Change – Peter B. deMenocal, Lamont-Doherty Earth Observatory of Columbia University from Kavli Frontiers of Science on Vimeo. The linkage between faunal change and climate change really has to do with a very basic observation, which is that organisms are fundamentally linked to the resource availability of a given landscape. As the energetics of […]
