First-of-its-Kind Map Details Extent of Plastic in Five Ocean Gyres

When a research team set sail on a nine-month, worldwide expedition in 2010 to study the impact of global warming on Earth's oceans, one of their projects was to locate the accumulations of plastic.

They found plenty. They explored the five huge gyres, which collectively contain tens of thousands of tons of plastic. The result was the creation of a compelling, first-of-its-kind map of this debris.

But in the process, they realized that the plastic in the gyres didn't begin to account for the enormous amount of plastic that's been manufactured since the mass production of plastic began in the mid 1940s.

In a National Geographic report, marine biologist Andres Cozar Cabañas, who was part of the Malaspina expedition led by the Spanish National Research Council, said:

"Our observations show that large loads of plastic fragments, with sizes from microns to some millimeters, are unaccounted for in the surface loads. But we don't know what this plastic is doing. The plastic is somewhere—in the ocean life, in the depths or broken down into fine particles undetectable by nets."

While there's been considerable alarm raised about these gyres of floating plastic, the missing plastic could be having negative impacts we don't yet know about. As National Geographic reports, the study of marine plastic debris is new, dating back only to 2004, when British marine biologist Richard Thompson concluded that most ocean debris is, in fact, plastic.

"Sadly, the accumulation of plastic in the deep ocean would be modifying this enigmatic ecosystem before we can really know it," said Cozar.

The discovery of the missing plastic raises a host of questions. Oceanographer Kara Lavender Law of the Cape Cod-based Sea Education Association, part of a team currently researching issues surrounding marine debris, told National Geographic:

"We are at the very early stages of understanding the accounting. If we think ten or a hundred times more plastic is entering the ocean than we can account for, then where is it? We still haven't answered that question. And if we don't know where it is or how it is impacting organisms, we can't tell the person on the street how big the problem is."

Among the possibilities: it's being consumed by small fish that are eaten by larger fish caught for human consumption, such as tuna and swordfish, and ending up in the human food system. Or it could be finding its way into the ecosystem of the world's least explored region, the deep ocean.

"Sadly, the accumulation of plastic in the deep ocean would be modifying this enigmatic ecosystem before we can really know it," said Cozar.

The Past 5 Years Were the Arctic's Warmest on Record

The Arctic is still warming at twice the rate of anywhere else on Earth, and the region's air temperatures in the past five years between 2014-2018 have exceeded all previous records since 1900, according to a peer-reviewed report released by the U.S. National Oceanographic and Atmospheric Administration (NOAA) on Tuesday.

The agency's 13th annual Arctic Report Card also concluded that 2018 was second only to 2016 in terms of the region's overall warmth.

3 Key Dangers of Solar Geoengineering and Why Some Critics Urge a Global Ban

By Justin Mikulka

A Harvard research team recently announced plans to perform early tests to shoot sunlight-reflecting particles into the high atmosphere to slow or reverse global warming.

These research efforts, which could take shape as soon as the first half of 2019, fall under the banner of a geoengineering technology known as solar radiation management, which is sometimes called "sun dimming."

Report: Current Climate Policies Will Warm the World by 3.3˚C

This past October, a widely disseminated United Nations report warned that far-reaching and significant climate impacts will already occur at 1.5˚C of warming by 2100.

But in a study released Tuesday, researchers determined that the current climate polices of governments around the world will push Earth towards 3.3˚C of warming. That's more than two times the aspirational 1.5˚C target adopted by nearly 200 nations under the 2015 Paris agreement.

The Lesson From a Burning Paris: We Can’t Tax Our Way Out of the Climate Crisis

By Wenonah Hauter

The images from the streets of Paris over the past weeks are stark and poignant: thousands of angry protesters, largely representing the struggling French working class, resorting to mass civil unrest to express fear and frustration over a proposed new gas tax. For the moment, the protests have been successful. French President Emmanuel Macron backed off the new tax proposal, at least for six months. The popular uprising won, seemingly at the expense of the global fight against climate change and the future wellbeing of our planet.
