Exxon Mobil’s scientists were remarkably accurate in their predictions about global warming, even as the company made public statements that contradicted its own scientists’ conclusions, a new study says.
The study, published in the journal Science on Thursday, looked at research that Exxon funded that didn’t just confirm what climate scientists were saying, but used more than a dozen different computer models that forecast the coming warming with precision equal to or better than government and academic scientists.

A team of University of Illinois researchers received a $2.5 million USDA grant for a project to explore conversion of food waste and swine manure into pavement binder and transportation fuels.
The proposal, “Pave the way: From Organic Waste to Renewable Roads With Advanced Resource Recovery Delineation (FORWARD),” is one of three projects funded through USDA’s National Institute of Food and Agriculture’s (NIFA) Bioproduct Pilot Program, which supports research and development of value-added products from agricultural commodities to enhance a circular bioeconomy.

The battle against the single-use plastic bag may not be won but it’s definitely under way.
Restrictions on their use are in place in almost a dozen US states and in many other countries around the world. And in many cases, these efforts have been successful at eliminating new sales of thin, wispy plastic bags that float up into trees, clog waterways, leech microplastics into soil and water and harm marine life. (Of course, these restrictions don’t address the plastic bags already out there that will take centuries to decompose.)
But this environmental success story of sorts masks another problem.
Many of us are drowning in reusable bags — cloth totes or thicker, more durable plastic bags — that retailers sell cheaply or give away to customers as an ostensibly greener alternative to single-use plastic. (I have 15 cotton totes and 12 heavy-duty plastic bags stashed in a kitchen drawer, only a few of which see the light of day.)
Campaigners say these bag hoards are creating fresh environmental problems, with reusable bags having a much higher carbon footprint than thin plastic bags. According to one eye-popping estimate, a cotton bag should be used at least 7,100 times to make it a truly environmentally friendly alternative to a conventional plastic bag.
The answer to what’s the greenest replacement for a single-use plastic bag isn’t straightforward, but the advice boils down to this: Reuse whatever bags you have at home, as many times as you can.
And here are some things to keep in mind as you hit the mall or grocery store.

A team of researchers analyzed fact checkers from four countries work in relation to climate change claims. They found their methods varied, that they most often checked claims made by politicians and from social media. They also provide arguments for the most effective practice of fact checking to ensure the public gets reliable, understandable information.

Emissions from copper-based antifouling paints are a well-known environmental problem. As much as 40 percent of copper inputs to the Baltic Sea come from antifouling paints on ships and leisure boats. According to a new study, this is completely unnecessary. When the researchers compared copper-based antifouling paint with biocide-free silicone-based paint, they found that the environmentally friendly alternative was best at keeping the fouling at bay.
