Scientists have discovered Antarctic Krill can digest or at least break up lumps of plastic into even smaller lumps – but when the krill were force fed large quantities of radioactive plastic over an extended period their ability to digest plastic deteriorated.

Krill found to break down microplastics – but it won’t save the oceans

Digestion of plastic into much smaller fragments ‘doesn’t necessarily help pollution’, Australian researchers say

A world-first study by Australian researchers has found that krill can digest certain forms of microplastic into smaller – but no less pervasive – fragments.

The study, published in Nature Communications journal on Friday, found that Antarctic krill, Euphausia superba, can break down 31.5 micron polyethylene balls into…

The Modern Warm Period Delimited

Watts Up With That?

Guest essay by David Archibald

This recent post discussed the end of the Modern Warm Period and the year that global cooling began. That post was inspired by a comment to a post on WUWT six to eight years ago to the effect that climate is controlled by the Sun’s magnetic flux – no need to worry about much else. The comment seemed to come from a warmer scientist – they are well funded, have plenty of time on their hands, some are smart and idle curiosity would get a few looking into what controls climate. The results would not be published of course. To paraphrase Mussolini, everything within the narrative, nothing outside the narrative, nothing against the narrative. If the Sun’s magnetic flux controls climate, you don’t have to worry about what goes on under the hood – the effect of EUV on the NAO, the GCR flux, the…

The Source Of The Heat

Watts Up With That?

Guest Post by Willis Eschenbach

Over at Dr. Judith Curry’s always excellent blog, she has a post headlined by a question, viz:

What are the main sources of heat that account for the incremental rise in temperature on Earth?

Let me start by saying that this is a horribly phrased question. Consider a parallel question:

What are the main sources of heat that account for the incremental rise in my body surface temperature when I put on a jacket?

I’m sure you can see the problem with Dr. Judith’s question—temperatures can rise without ANY new sources of heat or ANY change in existing sources of heat.

For example, regarding the climate system, every year there is more and more oil that goes into the ocean. This oil floats on the surface in a monomolecular layer, and it reduces both conduction and evaporation. As a result, the oceans end up slightly…

Reuters: Blame Consumers, Not China for Global Warming

Watts Up With That?

Guest essay by Eric Worrall

According to Clinton Climate Initiative backed green group C40, heavy emitters like China are not responsible for climate change; consumers in big cities who provide the demand for China’s products, especially rich consumers, are responsible for the CO2 emissions China produces fulfilling their needs.

Look at consumption when assigning blame for global warming, study says

Sebastien Malo

Calculating emissions of greenhouse gases, which are blamed for global warming, traditionally looks at where goods such as cellular phones or plastic cups are produced, they said.

But consumption-based emissions presents a fuller picture by attributing emissions to the consumers rather than the manufacturers, said Mark Watts, head of C40, an alliance…
