Global leaders urged to divert Brazilian government from ‘suicide’ path as Amazonian rainforest burns

Global leaders urged to divert Brazilian government from ‘suicide’ path as Amazonian rainforest burns

The Guardian reports: International pressure may be the only way to stop the Brazilian government from taking a “suicide” path in the Amazon, one of the country’s most respected scientists has said, as the world’s biggest rainforest continues to be ravaged by thousands of deliberate fires. The large number of conflagrations – set illegally to clear and prepare land for crops, cattle and property speculation – has prompted the state of Amazonas to declare an emergency, created giant smoke clouds…

Fires in the Amazon, the planet at risk

Fires in the Amazon, the planet at risk

Tierra Curry writes: In Brazil, the Amazon rainforest is now burning at a record rate. The greedy, short-sighted policies of Brazil’s far-right President Jair Bolsonaro are jeopardizing indigenous peoples and countless plants and animals. Indeed, in the midst of a climate emergency, Bolsonaro’s policies to slash environmental protections and develop the Amazon for mining, ranching and farming jeopardize the future of life on Earth as we know it. North America has already lost nearly 300 species to extinction. The toll…

Nations gather to tackle the world’s sixth mass extinction

Nations gather to tackle the world’s sixth mass extinction

The Guardian reports: From giraffes to sharks, the world’s endangered species could gain better protection at an international wildlife conference. The triennial summit of Convention on International Trade in Endangered Species (Cites), that began on Saturday, will tackle disputes over the conservation of great beasts such as elephants and rhinos, as well as cracking down on the exploitation of unheralded but vital species such as sea cucumbers, which clean ocean floors. Extraordinary creatures being driven to extinction by the exotic…

The latest threat to endangered species: The Trump administration

The latest threat to endangered species: The Trump administration

Carl Safina writes: Endangered species come on lists. But lists obscure relationships. What can it mean that a few mussels, some snails we’ve never heard of, obscure crayfish in marginal headwaters and some island-confined songbirds are vanishing? Some 1,650 species of animals and plants in the United States are listed under federal law as endangered or threatened. But when they are reduced to a line item on a list, their multimillion-year existences and roles in the complex living communities that…

Trump administration significantly weakens Endangered Species Act

Trump administration significantly weakens Endangered Species Act

The New York Times reports: The Trump administration on Monday announced that it would change the way the Endangered Species Act is applied, significantly weakening the nation’s bedrock conservation law and making it harder to protect wildlife from the multiple threats posed by climate change. The new rules would make it easier to remove a species from the endangered list and weaken protections for threatened species, the classification one step below endangered. And, for the first time, regulators would be…

How science got trampled in the rush to drill in the Arctic

How science got trampled in the rush to drill in the Arctic

Adam Federman reports: Every year, hundreds of petroleum industry executives gather in Anchorage for the annual conference of the Alaska Oil and Gas Association, where they discuss policy and celebrate their achievements with the state’s political establishment. In May 2018, they again filed into the Dena’ina Civic and Convention Center, but they had a new reason to celebrate. Under the Trump administration, oil and gas development was poised to dramatically expand into a remote corner of Alaska where it had…

‘Nature is declining at rates unprecedented in human history,’ says director of biodiversity conservation group

‘Nature is declining at rates unprecedented in human history,’ says director of biodiversity conservation group

The Guardian reports: From the tops of trees to the depths of the oceans, humanity’s destruction of wildlife is continuing to drive many species towards extinction, with the latest “red list” showing a third of all species assessed are threatened. The razing of habitat and hunting for bushmeat has now driven seven primates into decline, while overfishing has pushed two families of extraordinary rays to the brink. Pollution, dams and over-abstraction of freshwater are responsible for serious declines in river…

Viruses, the most abundant form of life on Earth, may be essential to the functioning of diverse ecosystems

Viruses, the most abundant form of life on Earth, may be essential to the functioning of diverse ecosystems

Arizona State University: The community of viruses is staggeringly vast. Occupying every conceivable biological niche, from searing undersea vents to frigid tundra, these enigmatic invaders, hovering between inert matter and life, circumnavigate the globe in the hundreds of trillions. They are the most abundant life forms on earth. Viruses are justly feared as ingenious pathogens, causing diseases in everything they invade, including virtually all bacteria, fungi, plants and animals. Recent advances in the field of virology, however, suggest that viruses…

The terrifying sound of a human voice

The terrifying sound of a human voice

Ed Yong writes: In the summer of 2017, the mountain lions, bobcats, and other residents of the Santa Cruz Mountains were treated to the dulcet tones of the ecologist Justin Suraci and his friends, reading poetry. Some of the animals became jittery. Others stopped eating. A few fled in fear. Suraci, who’s based at the University of California at Santa Cruz, wasn’t there to see their reactions. He and his colleagues had strung up a set of speakers that would…

News organizations are timidly changing their approach to covering climate crisis

News organizations are timidly changing their approach to covering climate crisis

The New York Times reports: As Europe heats up, Greenland melts and the Midwest floods, many news organizations are devoting more resources to climate change as they cover the topic with more urgency. In Florida, six newsrooms with different owners have taken the unusual step of pooling their resources and sharing their reporting on the issue. They plan to examine how climate change will affect the state’s enormous agriculture sector as well as “the future of coastal towns and cities…

Research on honeybees hit by Trump budget cuts

Research on honeybees hit by Trump budget cuts

CNN reports: The US Department of Agriculture has suspended data collection for its annual Honey Bee Colonies report, citing cost cuts — a move that robs researchers and the honeybee industry of a critical tool for understanding honeybee population declines, and comes as the USDA is curtailing other research programs. It’s also another step toward undoing President Barack Obama’s government-wide focus on protecting pollinators, including bees and butterflies, whose populations have plummeted in recent years.

These animal migrations are huge — and invisible

These animal migrations are huge — and invisible

Carl Zimmer writes: Last week, ladybugs briefly took over the news cycle. Meteorologists at the National Weather Service were looking over radar images in California on the night of June 4 when they spotted what looked like a wide swath of rain. But there were no clouds. The meteorologists contacted an amateur weather-spotter directly under the mysterious disturbance. He wasn’t getting soaked by rain. Instead, he saw ladybugs. Everywhere. Radar apparently had picked up a cloud of migrating ladybugs spread…

‘Frightening’ number of plant extinctions found in global survey

‘Frightening’ number of plant extinctions found in global survey

The Guardian reports: Human destruction of the living world is causing a “frightening” number of plant extinctions, according to scientists who have completed the first global analysis of the issue. They found 571 species had definitely been wiped out since 1750 but with knowledge of many plant species still very limited the true number is likely to be much higher. The researchers said the plant extinction rate was 500 times greater now than before the industrial revolution, and this was…

In ecology studies and selfless ants, E.O. Wilson finds hope for the future

Claudia Dreifus writes: No one else in biology has ever had a career quite like that of Edward O. Wilson. One of the world’s leading authorities on ants, an influential evolution theorist, and a prolific, highly honored author, E. O. Wilson—his first name comes and goes from bylines, but the middle initial is ever-present—has over several decades been at the center of scientific controversies that spilled out of the journals and into wider public awareness. Among activists in the environmental…

Puffins are starving to death because of climate change

Puffins are starving to death because of climate change

New Scientist reports: Hundreds of “severely emaciated” puffin carcasses have washed ashore on an Alaskan island, and researchers believe thousands more have died at sea as warming waters continue to shrink their food supply. Between October 2016 and January 2017, inhabitants of St Paul Island in the Bering sea found the starved bodies of more than 350 seabirds, primarily tufted puffins. Analysing the location of bird carcasses and wind data, Timothy Jones at the University of Washington in Seattle and…
