TOXIC TAX Motorists face rush-hour bans and pollution taxes as part of the Government's war on 'dirty' roads
July 25, 2017 04:55 PM - Steve Hawkes

MOTORISTS face rush-hour bans and pollution taxes in up to 17 towns and cities across the UK as the Government vows to clean up the ‘dirtiest roads’ in Britain.

Environment Secretary Michael Gove will pave the way for local authorities to slap yet more tax on drivers as part of his radical blueprint.

His plans reveal that air pollution needs to be addressed on 81 roads – 33 of which are outside London such as the A360 in Sheffield or A35 in Southampton.

Nitrogen dioxide emissions along each of them breach the legal limit.

Mr Gove will insist that councils first exhaust all other possible options to improve air quality, such as tackling chronic congestion.

The Coast Is Not So Clear

For nearly a century, the O’Shaughnessy seawall has held back the sand and seas of San Francisco’s Ocean Beach. At work even longer: the Galveston seawall, built after America’s deadliest hurricane in 1900 killed thousands in Texas.

Allowable 'carbon budget' most likely overestimated
July 24, 2017 12:32 PM - Andrea Elyse Messer, Pennsylvania State University

While most climate scientists, including the Intergovernmental Panel on Climate Change, implicitly define "pre-industrial" to be in the late 1800's, a true non-industrially influenced baseline is probably further in the past, according to an international team of researchers who are concerned because it affects the available carbon budget for meeting the 2 degrees Celsius (3.6 degrees Fahrenheit) warming limit agreed to in the Paris Conference of 2015.

The spirit of collaboration aboard Gulf of Mexico cruise
July 24, 2017 08:23 AM - NOAA

This summer, NOAA and partner scientists will conduct their most collaborative ocean acidification sampling of the Gulf of Mexico yet. Set to depart today, July 18th, the Gulf of Mexico Ecosystems and Carbon Cruise (GOMECC-3) will travel through international waters with 24 scientists from the United States, Mexico and Cuba on board.

Scientists Uncover Biogeochemical Controls on Occurrence and Distribution of PACs in Coals
July 21, 2017 09:56 AM - University of Science and Technology of China

The organic matter in coal contains polycyclic aromatic compounds (PACs) of varying quantities in diverse soluble and insoluble forms. PACs in coal are of special interest for organic geochemical studies as they have been successfully used as biological marker compounds (biomarkers) and indicators of thermal maturity.

However, challenges exist when applying PACs in understanding the organic geochemistry of coal. For example, what are the sources of PACs in coals? How do they transform during the long-term coal-formation history? Is there any regular relationship between the PAC and macro-molecular structural changes? 

Scientists calculate total amount of plastics ever produced

Humans have created 8.3 billion metric tons of plastics since large-scale production of the synthetic materials began in the early 1950s, and most of it now resides in landfills or the natural environment according to a study published today in the journal Science Advances.

University-led study looks to reduce methane gas emissions in cattle
July 20, 2017 08:05 AM - University of Lethbridge

Seeking to mitigate the greenhouse gas contributions of the region’s agricultural sector, a University of Lethbridge-led study has been granted $1.1 million by the federal government’s Agricultural Greenhouse Gases Program.

“Canadian farmers are great stewards of the land and the environment. These new investments are part of the government’s commitment to addressing climate change and ensuring our farmers are world leaders in the use and development of clean and sustainable technology and processes,” says Lawrence MacAulay, Minister of Agriculture and Agri-Food.

Dust particles in livestock facilities: Sweat the small stuff
July 19, 2017 02:40 PM - University of Illinois College of Agricultural, Consumer and Environmental Sciences

A beam of sunlight streams into your living room, illuminating a Milky Way of dust particles hanging in the air. Although the air looks thick, those visible dust particles are so big that they can’t reach the smallest branches of the respiratory tree in your lungs. It’s the dust we can’t see—smaller than 2.5 microns, called PM 2.5—that can cause allergies and other respiratory problems.
