‘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.

Nearly Half of Flowering Plant Species Face Threat of Extinction

“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.

‘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

Researchers Warn Great Salt Lake’s Retreat Threatens Crucial Ecosystem, Public Health

“The lake’s ecosystem is not only on the edge of collapse. It is collapsing,” said one ecologist.

By Julia Conley.  Published 1-7-2023 by Common Dreams

Scientists are warning Utah officials that the Great Salt Lake is shrinking far faster than experts previously believed, and calling for a major reduction in water consumption across the American West in order to prevent the lake from disappearing in the next five years.

Researchers at Brigham Young University (BYU) led more than 30 scientists from 11 universities and advocacy groups in a report released this week showing that the lake is currently at 37% of its former volume, with its rapid retreat driven by the historic drought that’s continuing across the West.

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).

Climate Emergency May Displace 216 Million Within Countries by 2050: World Bank

“The Groundswell report is a stark reminder of the human toll of climate change, particularly on the world’s poorest—those who are contributing the least to its causes.”

Underscoring the necessity of immediate and sweeping action to take on the climate emergency, a World Bank report revealed Monday that 216 million people across six global regions could be forced to move within their countries by midcentury.

Groundswell Part 2: Acting on Internal Climate Migration includes analyses for East Asia and the Pacific, North Africa, and Eastern Europe and Central Asia, building on a modeling approach from a 2018 report that covered Sub-Saharan Africa, South Asia, and Latin America. Continue reading

Tipping Point: UN Biodiversity Chief Warns Burning of Amazon Could Lead to ‘Cascading Collapse of Natural Systems’

“If we don’t work together, we are going to die together.”

The fires engulfing the Amazon rain forest are a sign that the Earth is approaching an environmental and ecological “tipping point” that all of humanity must work together to avoid, the U.N.’s top biodiversity expert said Friday. (Photo: ©Victor Moriyama/Greenpeace)

Unless world governments, consumers, and businesses all work together to address the root causes of the current burning of the Amazon rain forest, the Arctic, and forests in the Congo and Angola, the planet will continue careening toward a point of no return, the U.N.’s top biodiversity expert said Friday.

Cristiana Paşca Palmer, executive secretary of the U.N. Convention on Biological Diversity, called the fires that have torn through more than 1,300 square miles of the Amazon this year “extraordinarily concerning.” Continue reading

‘What Could Be More Important?’: World Leaders, Media Ignore Biodiversity Report Detailing Mass Extinction Event Now Underway

“The health of ecosystems on which we and all other species depend is deteriorating more rapidly than ever.”

Scientists at the United Nations’ intergovernmental body focusing on biodiversity sounded alarms earlier this month with its report on the looming potential extinction of one million species—but few heard their calls, according to a German newspaper report.

Deutsche Welle reported Thursday that partially because the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) released its report on what it called nature’s “unprecedented” decline on the same day that the Duke and Duchess of Sussex had their first child, news reports on the study’s grave implications were few and far between.

Scientists Warn Crashing Insect Population Puts ‘Planet’s Ecosystems and Survival of Mankind’ at Risk

“This is the stuff that worries me most. We don’t know what we’re doing, not trying to stop it, [and] with big consequences we don’t really understand.”

The first global scientific review of its kind reaches an ominous conclusion about the state of nature warning that unless humanity drastically and urgently changes its behavior the world’s insects could be extinct within a century.

Presented in exclusive reporting by the Guardian‘s environment editor Damian Carrington, the findings of the new analysis, published in the journal Biological Conservation, found that industrial agricultural techniques—”particularly the heavy use of pesticides”—as well as climate change and urbanization are the key drivers behind the extinction-level decline of insect populations that could herald a “catastrophic collapse of nature’s ecosystems” if not addressed.
