Scientists Won’t Classify Anthropocene as ‘Epoch’ Yet, But Say Human Impact Undeniable

The Anthropocene is classified as a geological “event” at this point—as are mass extinctions and rapid expansions of biodiversity.

The idea underpinning scientists’ push to recognize the current time period as a new geological epoch called the Anthropocene dates back more than 100 years, but on Tuesday, a committee of experts voted down the proposal to officially declare a new age defined by human beings’ impact on the Earth.

The panel, organized by the International Union of Geological Sciences (IUGS), was tasked with weighing whether the Holocene—the epoch that began at the close of the last ice age, more than 11,000 years ago—has ended, and if so, when precisely the Anthropocene began.

‘Shocking’ Share of Freshwater Fish Species at Risk of Extinction

“Ensuring freshwater ecosystems are well managed, remain free-flowing with sufficient water, and good water quality is essential to stop species declines… in a climate-resilient world,” one scientist said.

More than 20% of the world’s freshwater fish species are in danger of extinction, according to the first-ever assessment of the category by the International Union for Conservation of Nature.

The assessment was released Monday as part of an update to the IUCN Red List of Threatened Species published to coincide with the United Nations Climate Change Conference (COP28). It found that 3,086 out of 14,898 listed freshwater fish species are at risk of disappearing, and at least 17% of threatened fish species are impacted by the climate crisis.

“Effectively managing the plants and fungi that form the building blocks of our habitable planet is key to halting wider biodiversity loss and restoring Earth’s ecosystems to full function,” says a scientific report.

Global scientists warned Tuesday that 45% of known flowering plant species could be at risk of disappearing, underscoring the need for urgent international action to tackle the planet’s sixth mass extinction—the first driven by human activity.

That figure is among the key findings from State of the World’s Plants and Fungi, the fifth annual report from the U.K.’s Royal Botanic Gardens (RBG), Kew about such species amid the intertwined biodiversity crisis and climate emergency.

‘Very Bad News’: Human Activities Increased Extinction Rate of Species Groups by 35 Times

“What we’re losing are our only known living companions in the entire universe,” one study author said.

In what researchers call a “biological annihilation,” human activities are driving entire groupings of vertebrate species to extinction at a rate 35 times what it would have been without human interference.

The study, published in the Proceedings of the National Academy of Sciences Monday, found that 73 genera—the next thickest branch from species on tree of life—had been lost since A.D. 1500. Without the mass exploitation of the natural world that took off around that date with European colonization, the number lost in the past 500 years would have been only two, and it would have taken 18,000 years to reach 73 extinctions.

Green Groups Call on Biden Admin to End Support for ‘Scientifically Bankrupt’ Wildlife Killing

“The FWS is tasked with preventing extinctions, using sound science when making decisions to prevent those extinctions, and with being accountable to the entire public—not funding controversial predator-control actions for the purported benefit of a few.”

A rulemaking petition demanding an end to federal support for the removal of wolves and bears from states such as Alaska has been languishing at the U.S. Interior Department for almost two years, nearly three dozen conservation groups and scientists said in a letter to Interior Secretary Deb Haaland on Tuesday as they raised alarm about a recent killing operation.

Led by Public Employees for Environmental Responsibility (PEER), the Humane Society of the United States, and the Global Indigenous Council, 35 organizations wrote to the secretary to raise alarm about the U.S. Fish and Wildlife Service’s (FWS) continued funding of “irresponsible and controversial predator-control projects.”

Experts Urge Action to Mitigate ‘Risk of Extinction From AI’

It “should be a global priority alongside other societal-scale risks such as pandemics and nuclear war,” says a new statement signed by dozens of artificial intelligence critics and boosters.

On Tuesday, 80 artificial intelligence scientists and more than 200 “other notable figures” signed a statement that says “mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war.”

The one-sentence warning from the diverse group of scientists, engineers, corporate executives, academics, and other concerned individuals doesn’t go into detail about the existential threats posed by AI. Instead, it seeks to “open up discussion” and “create common knowledge of the growing number of experts and public figures who also take some of advanced AI’s most severe risks seriously,” according to the Center for AI Safety, a U.S.-based nonprofit whose website hosts the statement.

‘Grim’ Report Warns 40% of US Animals at Risk of Extinction

“We are currently experiencing and causing the Sixth Extinction—the mass extinction of species across the planet,” said the head of NatureServe, which also found a third of plants nationwide are under threat.

Underscoring the need for humanity to overhaul its relationship with nature, 34% of plants species and 40% of animal species across the United States are at risk of extinction while 41% of U.S. ecosystems could collapse, according to an analysis published Monday by the nonprofit NatureServe.

“For 50 years, the NatureServe Network has been collecting the information necessary to understand biodiversity imperilment in the United States. This new analysis of that data, a first in 20 years, makes crystal clear the urgency of that work,” said the group’s vice president for data and methods, Regan Smyth. Continue reading →

Report Reveals Corporate Capture of Global Biodiversity Efforts Ahead of Summit

“Their ‘solutions’ are carefully crafted in order to not undermine their business models; ultimately they do nothing for the environment,” said one Friends of the Earth campaigner.

With the next United Nations Biodiversity Conference set to kick off in Canada this week, a report out Monday details how corporate interests have attempted to influence efforts to protect the variety of life on Earth amid rampant species loss.

After a long-delayed and mostly virtual meeting in Kunming, China last year to work on a post-2020 global biodiversity framework (GBF), nearly 20,000 delegates are headed to Montreal for the second part of COP15, which will bring together countries party to a multilateral treaty, the Convention on Biological Diversity (CBD).

Climate Crisis Pushing Up to 1 in 6 US Tree Species Toward Extinction: Study

“Understanding the current state of trees within the U.S. is imperative to protecting those species, their habitats, and the countless communities they support.”

New research published Tuesday reveals both how chronically under-studied tree populations are in the U.S. and how the lack of resources devoted to trees has pushed as much as 16% of all tree species toward the threat of extinction.

After five years of study, a coalition of scientists from Botanic Gardens Conservation International, NatureServe, the U.S. Botanic Garden, and other groups revealed that as many as one in six U.S. tree species are in danger of becoming extinct due largely to disease and invasive insects—both of which have been quietly made more devastating to trees in recent years by the climate crisis.

90% of Marine Species Face Extinction Under Emissions Status Quo: Study

While the research predicts “a potentially bleak future for many marine species,” the authors say it “also measures how much our oceans and the life within them stand to benefit from both climate change mitigation and adaptation.”

A new study details the disastrous consequences that would result for marine life across the world’s oceans if current levels of fossil fuel emissions are maintained, with up to 90% of ocean species facing extinction.

Daniel Boyce, a research scientist at Bedford Institute of Oceanography in Nova Scotia, Canada, led the study examining 35,000 species of marine flora and fauna as well as bacteria and protozoans, devising a new analytical tool called the Climate Risk Index for Biodiversity (CRIB).
