COST OF FOOD COULD GO HIGHER WITH PROPOSED ‘MEAT TAX’

In order to address the harmful impacts of meat on human health and the environment, several different organizations have proposed that the U.S. government impose a tax on one of America’s favorite indulgences—meat.

Keeping global warming within 1.5 °C constrains emergence of aridification

Aridity—the ratio of atmospheric water supply (precipitation; P) to demand (potential evapotranspiration; PET)—is projected to decrease (that is, areas will become drier) as a consequence of anthropogenic climate change, exacerbating land degradation and desertification

As Trump’s Climate Denial Continues, Experts Take Flight to France

Many East Coasters will be returning to work today in bitter cold conditions after the second-coldest New Year on record.

The low temperatures over the festive period did not go unnoticed by President Donald Trump who tweeted in late December:

“In the East, it could be the COLDEST New Year’s Eve on record. Perhaps we could use a little bit of that good old Global Warming that our Country, but not other countries, was going to pay TRILLIONS OF DOLLARS to protect against. Bundle up!

The utter ignorance and stupidity underlying this tweet is staggering for someone with so much power. As the New York Times noted in response: “Trump’s tweet made the common mistake of looking at local weather and making broader assumptions about the climate at large.”

The paper added: “To use an analogy Mr. Trump might appreciate, weather is how much money you have in your pocket today, whereas climate is your net worth. A billionaire who has forgotten his wallet one day is not poor, anymore than a poor person who lands a windfall of several hundred dollars is suddenly rich. What matters is what happens over the long term.”

Why healthy soils and forests are key to climate protection and prosperity

What links climate change, poverty and migration? The Global Landscapes Forum addresses how land-use is central to global challenges that are more interconnected than many of us realize.

Author Says Soil Is Key To Addressing Effects of Climate Change

In 2013 the United Nations declared Dec. 5 to be World Soil Day, a recognition of the significance of healthy soil in both improving food security and nutrition, and mitigating the effects of climate change, including drought, flood, soil erosion and sea level rise. This year the U.N. held a conference at its New York headquarters on the theme of “caring for the planet starts from the ground.”

Didi Pershouse, founder of the Center for Sustainable Medicine in Thetford and author of The Ecology of Care, and the downloadable PDF which was released online in August, was one of five panelists invited to speak at this year’s conference.

GREEK YOGURT WASTE COULD BE USED IN JET FUEL AND LIVESTOCK FEED

Your Greek yogurt creates food waste that could one day be used in jet fuel.

That’s right—when Greek yogurt is made, it leaves behind liquid whey, which is the watery remains after protein is strained from milk. A process that mixes this waste with thousands of species of bacteria and some heat transforms the whey into a new material called bio-oil, which could be used in biofuels or additives in livestock feed.

and

Waste streams can be renewable feedstocks to produce biofuels and chemicals. Acid whey is an example waste stream and is produced by the Greek-yogurt industry in large volumes. This whey and other waste streams have been successfully converted into methane gas by anaerobic digesters with open cultures of microbial consortia (microbiomes). However, the revenue from methane has been relatively low. Until now, no other products could be produced with microbiomes from this waste stream. This has now changed. Here, we showed that acid whey was converted into valuable medium-chain carboxylic acids (MCCAs), such as n-caproic acid (n-hexanoic acid) and n-caprylic acid (n-octanoic acid), without addition of external electron acceptors.

Climate Change Has Come for Los Angeles

The time between Thanksgiving and Christmas is meant to be, in Southern California, the start of rainy season. Not this year. The Thomas Fire, the worst of those roiling the region this last week, grew 50,000 acres on Sunday alone; it has now burnt 270 square miles and forced 200,000 people from their homes. There is no rain forecast for the next seven to ten days, and as of Monday morning, Thomas is just, in the terrifying semi-clinical language of wildfires, “10% contained.” To a poetic approximation, it’s not a bad estimate of how much of a handle we have on the forces of climate change that unleashed it — which is to say, hardly any.

 

We could use further updating: Five of the 20 worst fires in California history have now hit since just September, when 245,000 acres in Northern California burned
