Why the ocean you know and love won’t exist in 50 years
Can sensitive coral reefs survive another human generation?
DAVID WALLACE-WELLS: I think there's basically no chance that coral reefs survive another generation. I think that we're looking at the total extinction of those biospheres by 2050 or so. There are some scientists who think there's some hope, and there have been some coral reefs that have recovered. But the impacts are so fast and so catastrophic, and we're so far from really changing course on carbon, it's hard for me to imagine that they endure, which means that the trips that we're now taking now to view those, we'll be taking really on the brink of mass extinctions.
And it's important to keep in mind that globally, we are living already through mass extinction. The World Wildlife Fund says that 60 percent of all vertebrate mammals have died since just 1970. There have been studies that say that insect populations may have fallen by as much as 75 percent over the last few decades. Animals are dying globally at rates never before seen in planetary history, and we are living through that and imposing those costs on the planet ourselves. The ocean is a particularly vulnerable system. It's not just the coral reefs. It's also the circulation patterns. It's the fish populations. And it happens we're also polluting the oceans with enormous amounts of plastic, which are really damaging. I think those people who really love the oceans should be quite terrified.
I think these ecosystems will be transformed really dramatically, very quickly, so that populations of fishermen that lived for decades on a particular fish community offshore will now have to find an entirely different way of life, because those fish will be swimming in totally different waters. And that is true at every level of the ocean ecosystem. The suffering there is not going to be any different than the suffering on land or the suffering experienced by humans. It will be quite catastrophic if we don't radically change course very, very quickly. And this is in part because the oceans do a lot to absorb warming. So the impacts are felt most intensely there.
If it were not for oceans, the planet would probably be already several degrees warmer than it is, but so much of the additional heat that we've been hot housing the planet with over the last few decades has been taken up by the ocean, and that means that the ocean has been totally transformed by that temperature.
- Coral reefs may not be able to survive another human decade because of the environmental stress we have placed on them, says author David Wallace-Wells. He posits that without meaningful changes to policies, the trend of them dying out, even in light of recent advances, will continue.
- The World Wildlife Fund says that 60 percent of all vertebrate mammals have died since just 1970. On top of this, recent studies suggest that insect populations may have fallen by as much as 75 percent over the last few decades.
- If it were not for our oceans, the planet would probably be already several degrees warmer than it is today due to the emissions we've expelled into the atmosphere.

Tech is rising and America's middle class is vanishing. Here's what to do.
- The rise of new technologies is making the United States more economically unequal, says Professor Ramesh Srinivasan. Americans should be pushing the current presidential candidates hard for answers on how they will bring economic security and how they will ensure that technological transitions benefit all of us.
- "We are at an inflection point when it comes to top-down control over very many different aspects of our lives through privatized corporate power over technology," says Srinivasan. Now is the time to debate solutions like basic income and worker-owned cooperatives.
- Concurrently, individuals should develop digital literacy and get educated on the potential solutions. Srinivasan recommends taking free online and open courses from universities like Stanford and MIT, and reading books and quality journalism on these issues.
Need to isolate? No problem! This philosopher is keeping the world posted on his isolation routine by Facebook.
- Like everybody else, Romanian philosopher Mihai Sora is stuck inside.
- He is keeping busy for a 103-year-old man, and keeping the world up to date on his indoor adventures with Facebook.
- His to-do list is impressive, but not so impressive it can't be used by most people.
Playing and being creative shouldn't stop when you grow up.
