The North Atlantic Ocean Circulation is a double-edged sword when it comes to ocean acidification. In the past, it has kept the North Atlantic Ocean less acidic – and more hospitable – than the Pacific Ocean. Today, the same circulation has the potential toconvey fast acidification to the ocean depth as climate change alters both the atmosphere and the surface ocean.
Humans have long looked to the ocean for opportunities, sustenance, and growth. Today, advocates of “Blue Growth” aim to foster sustainable economic growth in the marine sector. Absent in the grandiose vision, however, is where our interaction with the ocean first began: fishing. Global fisheries production has stagnated: ecology is fragile, regulations are strict, and fish prices are low. So, what is the future for marine fisheries? What will be its role in Blue Growth?
The stories about the poaching of African elephants are deeply imbedded in the carbon isotope tracers that make up the prized tusks. A group of scientists used these tracers to uncover the realities of poaching activities threatening Africa’s elephants today.
To grow or not to grow? That is not the question. Policymakers are unconsciously limited in their choices regarding climate policy by the conventional expectation to achieve economic growth. In a recent article, a researcher examines different perspectives on growth-versus-climate debate and points out a way forward.
