The news out of the Rio+20 Earth Summit has been bleak. World leaders, yet again caught in the headlights of financial crises and electoral cycles, fundamentally failed us and the planet. However, there is a bright spot—and it is blue. Both the formal Rio text and the voluntary, on-the-ground and on the water commitments nations made, are a reason for hope.

The oceans sequester, or absorb, about 30 percent of the CO2 we spew into the atmosphere from burning fossil fuels. But this remarkable environmental service, helping to moderate the climate impact of our fossil fuel addition, comes at a heavy cost—ocean acidification.

Ocean acidification has created renewed urgency to reduce pollution, over fishing and coastal damage to build ocean ecosystem resilience against the adverse effects of carbon pollution. The only long-term solution to acidification is deep cuts in CO2 emissions, but to ensure that as much marine biodiversity as possible survives the inevitable acidification in the coming decades, building resilience is essential and urgent.

More than 130 heads of state, other leaders, and some 50,000 participants from all over the globe are gathering this week in Rio de Janeiro, the most-visited city in the southern hemisphere, for the Rio+20 Earth Summit. I am here with Martin Wagner, head of the Earthjustice International program, and Erika Rosenthal, Earthjustice attorney and veteran of many international environmental negotiations, and we want to share a few glimpses into what is going on as this historic event unfolds.

The summit offers the world an opportunity to deepen and broaden the reach of environmental commitments that are fundamental to sustainable development and reducing poverty around the world, and to support and extend good work that is happening in many countries and under many other international agreements.

Unlike the grand, path-breaking outcomes that the nations accomplished at the first Rio Earth Summit 20 years ago, this summit is focused on improving implementation of existing agreements for better outcomes for the people and the planet. Some in the news media have focused on the lack of grand new treaties, but that narrative misses the point. Although political realities may preclude great leaps forward, and certainly the summit is not producing the sorts of outcomes that it should, we can still work hard for incremental change when the opportunities exist. That’s what Earthjustice is doing at home and that's what we are doing here. In particular here in Rio, we’re pressing for progress on two important issues: ocean protection and reducing fossil fuel use.

Australia announces world’s largest marine reserve
Just in time for this week’s Rio+20 Earth Summit, Australia has announced its plans to create the world’s largest marine reserve, reports the BBC. The protected zone will cover more than a third of Australia’s waters (about 3 million square kilometers) and will include restrictions on fishing as well as oil and gas exploration. The announcement comes on the heels of another big environmental win, courtesy of the Australian government, which last week announced that it is putting a stop to a billion-dollar coal project that could negatively impact the Great Barrier Reef. Though this latest move to create a marine reserve didn’t quite go as far as some environmentalists groups would have liked, it’s a great first step in building resilient oceans, which are already being battered by overfishing, pollution, habitat loss, and now ocean acidification.

Turtle couple that’s been dating for decades calls it quits
After more than 100 years of companionship, a pair of Giant Turtles at an Austrian zoo have decided to call it quits, reports the Austrian Times. According to the zoo staff, the century-long love fest came to a seemingly sudden end after the female turtle, Bibi, attacked her partner by biting off a chunk of his shell. Afterwards, Bibi continued attacking the male turtle until he was moved to a different cage. Since there have been no apparent changes in the turtles’ routine, the zoo suspects that Bibi may simply want to be single and nothing—including “romantic good mood food” and couples —will change her mind.
