The most damaging farm products? Organic, pasture-fed beef and lamb

The most damaging farm products? Organic, pasture-fed beef and lamb

George Monbiot writes: Perhaps the most important of all environmental issues is land use. Every hectare of land we use for extractive industries is a hectare that can’t support wild forests, savannahs, wetlands, natural grasslands and other crucial ecosystems. And farming swallows far more land than any other human activity. What are the world’s most damaging farm products? You might be amazed by the answer: organic, pasture-fed beef and lamb. I realise this is a shocking claim. Of all the…

The legacy of James Lovelock

The legacy of James Lovelock

John Gribbin writes: Jim Lovelock (never ‘James’) is remembered as the father of the Gaia hypothesis: the idea that Earth is a self-regulating living organism. Few accepted his argument that this should be elevated to the status of a theory, even though it generated predictions about environmental changes that were borne out by subsequent observations. As a heuristic model, however, Gaia profoundly influenced thinking about the environment and how we interact with it, giving rise to the field of Earth-system…

Scientists warn of dire effects as Mediterranean heats up

Scientists warn of dire effects as Mediterranean heats up

The Associated Press reports: While vacationers might enjoy the Mediterranean Sea’s summer warmth, climate scientists are warning of dire consequences for its marine life as it burns up in a series of severe heat waves. From Barcelona to Tel Aviv, scientists say they are witnessing exceptional temperature hikes ranging from 3 degrees Celsius (5.4 Fahrenheit) to 5 degrees Celsius (9 Fahrenheit) above the norm for this time of year. Water temperatures have regularly exceeded 30 C (86 F) on some…

Nature is in crisis. A UN report says short-sighted economics is to blame

Nature is in crisis. A UN report says short-sighted economics is to blame

Grist reports: When governments make decisions, economic considerations often trump everything else — human well-being, social connections, the health of the environment. According to a new report from the United Nations, this imbalance is driving the global biodiversity crisis and the human suffering associated with it. “Despite the diversity of nature’s values,” the report says, “most policymaking approaches have prioritized a narrow set of values at the expense of both nature and society, as well as future generations.” It calls…

Pollen and heat — a looming challenge for global agriculture

Pollen and heat — a looming challenge for global agriculture

Carolyn Beans writes: Last June, Aaron Flansburg felt the temperature spike and knew what that meant for his canola crop. A fifth-generation grower in Washington state, Flansburg times his canola planting to bloom in the cool weeks of early summer. But last year, his fields were hit with 108-degree Fahrenheit heat just as flowers opened. “That is virtually unheard of for our area to have a temperature like that in June,” he says. Yellow blooms sweltered, reproduction stalled, and many…

The genetic power of ancient trees

The genetic power of ancient trees

Jim Robbins writes: In 2005, several of the centuries-old ponderosa pine trees on my 15 acres (0.06 sq km) of forest in the northern Rocky Mountains in Montana suddenly died. I soon discovered they were being brought down by mountain pine beetles, pernicious killers the size of the eraser on a pencil that burrow into the tree. The next year the number of dying trees grew exponentially. I felt powerless and grief-stricken as I saw these giant, sky-scraping trees fading…

How I started to see trees as smart

How I started to see trees as smart

Matthew Hutson writes: A couple of decades ago, on a backpacking trip in the Sierra Nevada, I was marching up a mountain solo under the influence of LSD. Halfway to the top, I took a break near a scrubby tree pushing up through the rocky soil. Gulping water and catching my breath, I admired both its beauty and its resilience. Its twisty, weathered branches had endured by wresting moisture and nutrients from seemingly unwelcoming terrain, solving a puzzle beyond my…

Lowly mushrooms may be key to ecosystem survival in a warming world

Lowly mushrooms may be key to ecosystem survival in a warming world

Elizabeth Pennisi writes: The red, orange, and spotted mushrooms that sprout up after it rains are doing more than adding color to the landscape. The fungi that produce them could be keeping the natural world productive and stable, according to a new study. Indeed, they may be critical to the health of Earth’s ecosystems, says Matthias Rillig, a soil ecologist at the Free University Berlin who was not involved with the work. There are 70,000 known kinds of fungi. These…

Indian court rules nature has legal status on par with humans. We are required to protect it

Indian court rules nature has legal status on par with humans. We are required to protect it

Inside Climate News reports: The highest court in one of India’s 28 states ruled last month that “Mother Nature” has the same legal status as a human being, which includes “all corresponding rights, duties and liabilities of a living person.” The decision from Madras High Court, located in the southeastern state of Tamil Nadu, also said that the natural environment is part of the human right to life, and that humans have an environmental duty to future generations. “The past…

A climate-driven decline of tiny dryland lichens could have major global impacts

A climate-driven decline of tiny dryland lichens could have major global impacts

Inside Climate News reports: Lichens that help hold together soil crusts in arid lands around the world are dying off as the climate warms, new research shows. That would lead deserts to expand and also would affect areas far from the drylands, as crumbling crusts fill winds with dust that can speed snowmelt and increase the incidence of respiratory diseases. Biologically rich soil crusts, sometimes called cryptobiotic soils or biocrusts, are spread out across dry and semi-dry regions of every…

Why you should care about the insect crisis

Why you should care about the insect crisis

Allie Wilkinson writes: Imagine a world without insects. You might breathe a sigh of relief at the thought of mosquito-free summers, or you might worry about how agriculture will function without pollinators. What you probably won’t picture is trudging through a landscape littered with feces and rotting corpses — what a world devoid of maggots and dung beetles would look like. That’s just a snippet of the horrifying picture of an insect-free future that journalist Oliver Milman paints in the…

Seed banks — the last line of defense against a global food crisis

Seed banks — the last line of defense against a global food crisis

The Guardian reports: As the risks from the climate crisis and global conflict increase, seed banks are increasingly considered a priceless resource that could one day prevent a worldwide food crisis. Two in five of the world’s plant species are at risk of extinction, and though researchers estimate there are at least 200,000 edible plant species on our planet, we depend on just three – maize, rice and wheat– for more than half of humanity’s caloric intake. There are roughly…

Mushrooms communicate with each other using up to 50 ‘words’, scientist claims

Mushrooms communicate with each other using up to 50 ‘words’, scientist claims

The Guardian reports: Buried in forest litter or sprouting from trees, fungi might give the impression of being silent and relatively self-contained organisms, but a new study suggests they may be champignon communicators. Mathematical analysis of the electrical signals fungi seemingly send to one another has identified patterns that bear a striking structural similarity to human speech. Previous research has suggested that fungi conduct electrical impulses through long, underground filamentous structures called hyphae – similar to how nerve cells transmit…

Falling oxygen levels are putting ocean ecosystems on life support

Falling oxygen levels are putting ocean ecosystems on life support

Jessica Camille Aguirre writes: People who make their living catching fish on the open ocean first noticed the strange phenomenon a few decades ago. It occurred in the shadow zones, the spots between the great ocean currents where sea water doesn’t circulate, off the coasts of Peru, West Africa, and California. The fisher people shared the knowledge among them like a common secret, a bounty that had an even stranger explanation: Sometimes, when the conditions were right, fish would swim…

Ecuador’s high court rules that wild animals have legal rights

Ecuador’s high court rules that wild animals have legal rights

Inside Climate News reports: Wild animals possess distinct legal rights, including to exist, to develop their innate instincts and to be free from disproportionate cruelty, fear and distress, Ecuador’s top court ruled in a landmark decision interpreting the country’s “rights of nature” constitutional laws. The 7-2 ruling handed down last month in Quito is believed to be the first time a court has applied the rights of nature—laws that recognize the legal rights of ecosystems to exist and regenerate—to an…
