100 companies to blame for 71% of carbon “pollution”, but world’s worst corporates are Big Government

by JoNova, August 2017


Since 1988, a mere 100 companies have been responsible for 71 percent of the entire world’s industrial greenhouse gas emissions.

This data comes from an inaugural report published by the Carbon Disclosure Project (CDP), an environmental non-profit. Charting the rapid expansion of the fossil fuel industry in the last 28 years, they have now released some truly staggering numbers on the world’s major carbon polluters.

Plastics Yet Again

by Kip Hansen, July 28, 2017 in WUWT


The New York Times’ article breathlessly reports:

“From the 1950s to today, 8.3 billion metric tons of plastic have been produced, with around half of it made since 2004. And since plastic does not naturally degrade, the billions of tons sitting in landfills, floating in the oceans or piling up on city streets will provide a marker if later civilizations ever want to classify our era. Perhaps they will call this time on Earth the Plastocene Epoch.”

Contamination of the Arctic reflected in microbial metagenomes from the Greenland ice sheet

by A.L. Hauptmann et al., July 11, 2017


Globally emitted contaminants accumulate in the Arctic and are stored in the frozen environments of the cryosphere. The microbial potential to degrade anthropogenic contaminants, such as toxic and persistent polychlorinated biphenyls, was found to be spatially variable and not limited to regions close to human activities.

Plastic pollution in the Antarctic worse than expected

by British Antarctic Survey, June 19, 2017 in ClimateChangeDispatch


The levels of microplastic particles accumulating in the Antarctic are much worse than expected, a team of experts has warned.

The continent is considered to be a pristine wilderness compared to other regions and was thought to be relatively free from plastic pollution. However new findings by scientists from University of Hull and British Antarctic Survey (BAS) have revealed that recorded levels of microplastics are five times higher than you would expect to find from local sources such as research stations and ships

River plastic emissions to the world’s oceans

by Laurent Lebreton et al., June 7, 2017 in Nature Communication


Plastics in the marine environment have become a major concern because of their persistence at sea, and adverse consequences to marine life and potentially human health. Implementing mitigation strategies requires an understanding and quantification of marine plastic sources, taking spatial and temporal variability into account. Here we present a global model of plastic inputs from rivers into oceans based on waste management, population density and hydrological information.
