Queen Elizabeth has no patience for plastic.

Here’s how humanity could all but ensure its own demise: Dig up all the coal we have left and burn it, warming the planet 4 to 6 degrees C.

But that worst-case scenario doesn’t match up with what’s really happening in the world, Justin Ritchie, lead author of a new study published in Environmental Research Letters, told Grist.

That’s because money spent on climate change measures goes further than it did 30 years ago. Plus, baseline trends show greenhouse gas emissions are on the decline. Most studies underestimate the effect these factors have on global decarbonization.

The study indicates that the goals outlined in the Paris Agreement are more achievable than previously projected — but that’s not to say humanity isn’t in deep trouble.

It’s not “4 to 6 degrees bad,” Ritchie says. “It’s 3 degrees bad. You can’t say we don’t have to worry about implementing policies, we do. But it’s not going to reach the truly catastrophic scenarios.”

Another recent study published in the same journal shows that if all the coal plants currently planned actually get built, humanity could blow past the Paris goal of limiting warming to 2 degree C above pre-industrial levels.

Ritchie said his research doesn’t counteract that finding. “There’s a whole range of scenarios that can occur,” he says. “What our paper is trying to do is look at that whole range and how can we design policies that are more robust.”

The EPA hired a ‘war room’-style media monitoring company.

Forests in the American West are having a harder time recovering from wildfires because of (what else?) climate change, according to new research published in Ecology Letters.

Researchers measured the growth of seedlings in 1,500 wildfire-scorched areas in Colorado, Wyoming, Washington, Idaho, and Montana. Across the board, they found “significant decreases” in tree regeneration, a benchmark for forest resilience. In one-third of the sites, researchers found zero seedlings.

The warmest, driest forests were hit especially hard.

“Seedlings are more sensitive to warm, dry conditions than mature trees, so if the right conditions don’t exist within a few years following a wildfire, tree seedlings may not establish,” said Philip Higuera, a coauthor of the study.

Earlier this month, a separate study found that ponderosa pine and pinyon forests in the West are becoming less resilient due to droughts and warmer temperatures. Researchers told the New York Times that as trees disappear, some forests could shift to entirely different ecosystems, like grasslands or shrublands.

You’d think the rapid reconfiguration of entire ecosystems would really light a fire under us to deal with climate change, wouldn’t you?

The 3 Holiday Plants That Clean the Air

Shares

You don’t have to have a green thumb — or be vegan — to delight in the presence of plants. Gardening and food consumption aside, household plants are pretty miraculous to have around due to their numerous superpowers. And what better time to take advantage than during the holidays, when we could all use as many superpowers as possible.

Health Benefits of Plants

Most of us realize the pluses of incorporating greenery in our indoor environments, including 20 percent less dust, according to a study by Washington State University. Besides magical fairy dusting and beautification of a space, plants can absorb up to 10 percent of carbon dioxide and release oxygen back into the air we breathe. Plants even reduce stress and boost morale when placed in offices, simultaneously reducing airborne bacteria.

Plants Improve Indoor Air Quality

What many people are unaware of is the fact that certain plants do all of the above while also removing toxic gases and chemical vapors commonly found in our indoor environments, according to studies by the National Aeronautics and Space Administration (NASA).

Green building today is great for energy efficiency, but it’s not always so great for our health. In 1973, NASA realized that indoor air pollution in tightly sealed structures could present health-related problems. The Clean Air Study, led by Dr. B.C. Wolverton in conjunction with the Associated Landscape Contractors of America, discovered the miraculous benefits of 50 houseplants (three of them being holiday plants) that are exceptional little air scrubbers. These must be potted plants in soil and ideally, one should be placed every 100 feet for maximum air filtration benefits, as advised by NASA.

3 Holiday Plants that Remove Chemicals

Three popular holiday plants — the Poinsettia, the Norfolk Island Pine and the Christmas Cactus — work as natural, mini air purifiers. They provide an affordable defense by absorbing volatile organic compounds (VOCs), such as formaldehyde, benzene and ammonia, from the air through the tiny openings in their leaves (stomata) and their root microbes. Let’s take a closer look at each plant.

1. Poinsettia

You’ll recognize this holiday beauty from its bright, vibrant bracts (leaves). Ironically, it’s not the flower of this plant, rather the leaves, that are grown in pink, red, white, speckled or marbled. Discovered by Joel Poinsett in 1830 in Southern Mexico, this plant prefers semi-shade. It’s easy to grow and pretty resistant to insect infestation. Water when the top layer is dry.

2. Norfolk Island Pine

This evergreen often serves as a mini Christmas tree with a similar appeal. One variety, the heterophylla, is suitable for indoors and can grow up to 10 feet high! It was discovered by Captain Cook and botanist Sir Joseph Banks. The Norfolk Island Pine prefers full sun to semi-shade. Use water sparingly in the winter and mist often.

3. Christmas Cactus

This beautiful cactus with bright red buds blooms fully in December. Unlike most plants, this cactus removes CO2 and releases oxygen at night, making it a great plant for the bedroom. It prefers semi-sun and is highly resistant to insect infestation. Allow it to dry between waterings.

There you have it — the perfect holiday or housewarming gift. Your host or hostess will be breathing easier through the hustle and bustle while enjoying a more beautiful and relaxing home.

Climate science opponent Lamar Smith will retire from Congress.

Poor dumb turtles and fish, always chomping on the ubiquitous plastic in the water by accident — or so the story went, until a handful of recent studies suggested sea creatures may actually be choosing to eat plastic.

In one of these experiments, researchers took single grains of sand and particles of microplastic — both around the same size and shape — and dropped them onto coral polyps. The tiny creatures responded to the plastic the same way they would to a tasty piece of food, stuffing the bits of trash into their mouths like so many Snickers Minis.

“Plastics may be inherently tasty,” Austin Allen, a study coauthor and marine science doctoral student at Duke University, told the Washington Post.

Coral polyps rely on chemical sensors — taste buds, essentially — to determine whether something is edible or not. And they were repeatedly chosing to swallow plastic during the study. Only once in 10 trials did a polyp make the same mistake with sand. In fact, the cleaner and fresher and more plastic-y the plastic was, the more readily the coral gulped it down.

While the long-term effects of the plastic-saturation of the planet are still unknown, this research suggests that accidentally tasty microplastics could pose an extra hazard to already beleaguered corals around the world.

Dinosaurs Without Bones

Dinosaur Lives Revealed by Their Trace Fossils

Anthony J. Martin

Genre: Science & Nature

Price: $11.99

Publish Date: March 4, 2014

Publisher: Pegasus Books

Seller: OpenRoad Integrated Media, LLC


What if we woke up one morning all of the dinosaur bones in the world were gone? How would we know these iconic animals had a 165-million year history on earth, and had adapted to all land-based environments from pole to pole? What clues would be left to discern not only their presence, but also to learn about their sex lives, raising of young, social lives, combat, and who ate who? What would it take for us to know how fast dinosaurs moved, whether they lived underground, climbed trees, or went for a swim? Welcome to the world of ichnology, the study of traces and trace fossils—such as tracks, trails, burrows, nests, toothmarks, and other vestiges of behavior—and how through these remarkable clues, we can explore and intuit the rich and complicated lives of dinosaurs. With a unique, detective-like approach, interpreting the forensic clues of these long-extinct animals that leave a much richer legacy than bones, Martin brings the wild world of the Mesozoic to life for the twenty-first-century reader. Past Praise for Anthony J. Martin: “Martin shows how ancient trace fossils directly relate to modern traces and tracemakers, among them insects, crabs, shorebirds, alligators, and sea turtles. The result is an aesthetically appealing and scientifically accurate book.” — Birdbooker Report “The pedagogy is excellent, and the explanations of technical material are accessible.” —Raymond Freeman-Lynde, University of Georgia “Full of valuable and useful information.” — Geological Magazine Anthony J. Martin is a professor at Emory University, a paleontologist, geologist, and one of the world’s most accomplished ichnologists. He is the co-discoverer of the first known burrowing dinosaur, found the oldest dinosaur burrows in the geologic record, and documented the best assemblage of polar-dinosaur tracks in the Southern Hemisphere. He is the author of two textbooks on dinosaurs and lives in Atlanta, Georgia.

Climate Change

What Everyone Needs to Know®

Joseph Romm

Genre: Earth Sciences

Price: $10.99

Publish Date: November 5, 2015

Publisher: Oxford University Press

Seller: Oxford University Press


Climate change will have a bigger impact on humanity than the Internet has had. The last decade's spate of superstorms, wildfires, heat waves, and droughts has accelerated the public discourse on this topic and lent credence to climatologist Lonnie Thomson's 2010 statement that climate change "represents a clear and present danger to civilization." In June 2015, the Pope declared that action on climate change is a moral issue. This book offers the most up-to-date examination of climate change's foundational science, its implications for our future, and the core clean energy solutions. Alongside detailed but highly accessible descriptions of what is causing climate change, this entry in the What Everyone Needs to Know series answers questions about the practical implications of this growing force on our world: · How will climate change impact you and your family in the coming decades? · What are the future implications for owners of coastal property? · Should you plan on retiring in South Florida or the U.S. Southwest or Southern Europe? · What occupations and fields of study will be most in demand in a globally warmed world? · What impact will climate change have on investments and the global economy? As the world struggles to stem climate change and its effects, everyone will become a part of this story of the century. Here is what you need to know.

British Columbia is having its worst wildfire season in recorded history.

That’s all kinds of scary. If there’s one place on Earth that would be the worst possible spot for a giant volcanic chain, it’s beneath West Antarctica. Turns out, it’s not a great situation to have a bunch of volcanoes underneath a huge ice sheet.

In a discovery announced earlier this week, a team of researchers discovered dozens of them across a 2,200-mile swath of the frozen continent. Antarctica, if you’re listening, please stop scaring us.

The study that led to the discovery was conceived of by an undergraduate student at the University of Edinburgh, Max Van Wyk de Vries. With a team of researchers, he used radar to look under the ice for evidence of cone-shaped mountains that had disturbed the ice around them. They found 91 previously unknown volcanoes. “We were amazed,” Robert Bingham, one of the study’s authors, told the Guardian.

The worry is that, as in Iceland and Alaska, two regions of active volcanism that were ice-covered until relatively recently, a warming climate could help these Antarctic volcanoes spring to life soon. In a worst-case scenario, the melting ice could release pressure on the volcanoes and trigger eruptions, further destabilizing the ice sheet.

“The big question is: how active are these volcanoes? That is something we need to determine as quickly as possible,” Bingham said.

EPA employees speak out about the agency’s problems under Trump.

Two years ago, a paper came out arguing that America could cheaply power itself on wind, water, and solar energy alone. It was a big deal. Policy makers began relying on the study. A nonprofit launched to make the vision a reality. Celebrities got on board. We named the lead author of the study, Stanford University professor Mark Jacobson, one of our Grist 50.

Now that research is under scrutiny. On Monday, 21 scientists published a paper that pointed out unrealistic assumptions in Jacobson’s analysis. For instance, Jacobson’s analysis relies on the country’s dams releasing water “equivalent to about 100 times the flow of the Mississippi River” to meet electricity demand as solar power ramps down in the evening, one of the critique’s lead authors, Ken Caldeira of the Carnegie Institution for Science, told the New York Times.

Jacobson immediately fired back, calling his critics “nuclear and fossil fuel supporters” and implying the authors had sold out to industry. This is just wrong. These guys aren’t shills.

It’s essentially a family feud, a conflict between people who otherwise share the same goals. Jacobson’s team thinks we can make a clean break from fossil fuels with renewables alone. Those critiquing his study think we need to be weaned off, with the help of nuclear, biofuels, and carbon capture.

Grist intends to take a deeper look at this subject in the coming weeks, so stay tuned.
