A dearth of research leaves scientists mostly flying blind as to insect abundance and diversity in the tropics. But a new study identifies losses in Brazil of terrestrial species, while aquatic species seem to be holding steady.
A new study has found that nearly 90% of assessed marine life will be at high or critical risk by the year 2100 if climate change accelerates along a high-emissions…
Taiwanese filmmaker Chris Chang moved to Berkeley, California, in August 2021, when the state was already experiencing a deep environmental crisis. In 2020, thousands of wildfires in California burnt through…
Less than a decade since conservation actions helped pull the hyacinth macaw out of Brazil’s endangered species list, the iconic cobalt-blue bird is back in the red, driven there by…
Birds, bats, elephants, apes, rodents and many other animal species spread plant seeds throughout the world. But as those animal populations diminish, so do the plants that rely on wildlife to shift their range, especially as climate change worsens.
Biodiversity. When you hear this word, what do you picture? Iconic animals like African elephants, gray wolves and humpback whales? Or multicolored coral species that make up a reef system?…
For years, Joaquim Garrabou donned scuba gear and dove into the waters of the Scandola Marine Reserve in Corsica to find a paradise. Twenty meters (66 feet) beneath the surface,…
Fungi account for around half of the living organisms in our soils, yet we tend to only notice them when a conspicuous mushroom or toadstool pops up and draws our…
Hurricane Ida’s warpath is the latest in a litany of natural disasters, estimated to have cost the world $210 billion in damage in 2020, that is shining a spotlight on climate change.…
In July 2021, the U.S. Fish & Wildlife Service announced that 866 West Indian manatees (Trichechus manatus) had died in the state of Florida in the first seven months of…
The climate in the Amazon has been changing over the last few decades. The average temperature in the basin rose about 1º Celsius (1.8° Fahrenheit) between 1979 and 2018, with…
Gorillas, chimpanzees and bonobos face a bleak future thanks to a perfect storm of human-driven factors, a recent study shows. The triple whammy of the climate crisis, growing human population,…
The push to halt climate change too often neglects the interconnected issue of biodiversity loss, according to a recent report from a panel of scientists with the United Nations. “What…
The world is brimming with bad news about people failing to take care of the Earth. But there is a way to change the narrative, says Canadian conservationist Harvey Locke.…
Simple mathematical models suggest overshooting Paris climate accord emission targets for a short time won’t immediately trigger some environmental tipping points, allowing time to act.
More numerous than stars, our planet’s microbes play an integral role in helping life thrive on Earth. But what happens when climate change, pollution and ocean acidification impact microbes? — We don’t know.
Endemic species face a greater risk of going extinct because of climate change than native or introduced species, a recent study in Biological Conservation has found. Species that are exclusive…
In 2012, researchers described a teensy, aspirin-sized chameleon, Brookesia nana, from a thin slice of rainforest in northern Madagascar. The species, which experts believe is the smallest reptile in the world, grabbed plenty…
More than a decade after the Planetary Boundaries framework was first proposed by top scientists, we are no closer to changing our destructive trajectory — but 2021 gives us three opportunities to act.
In the arctic tundra of northeastern Siberia lies a graveyard of a now-extinct species of megafauna, the woolly rhinoceros, dating back 50,000 years. Now, a new genomic analysis of the…
The growing consensus that the earth is in the throes of a sixth mass extinction has focused attention on a centuries-old ecological puzzle: why do species suddenly disappear by the…
Outer space, the ocean depths and quantum physics are areas ripe for discovery, the underexplored frontiers of science. But another frontier may be hidden in plain sight, right under your…
The world’s protected areas are largely a jumble of disjointed refuges, separated from each other by the encroachment of human impacts, a recent study has found. Fewer than 10% of…
By 2070, rising soil temperatures could cause germination failure in 20% of tropical plants, and reduced rates in more than 50%, with the potential to disrupt and alter tropical ecosystems.
Habitat loss and climate change are often blamed for the decreasing numbers of migratory shorebirds in a major flyway in the Asia-Pacific region in recent years. But it might be…
Pixaim is one of the remaining quilombos on the Atlantic coast, an Afro-Brazilian settlement already gravely impacted by upstream dams. Now climate change could doom it.
Life can’t function without insects. At least, not for long. Dutifully, they pollinate, break down waste, cycle nutrients, move seeds, and touch every node in the web of life, filling…
Large biomes, like the Amazon rainforest, have closely linked habitats and species, which could lead to a domino effect and a rapid ecosystem collapse; even small effects can cause a crash over time.
Environmental degradation has already triggered disease outbreaks in Brazil. The risk of a new emergent zoonotic disease arising there, like COVID-19, is intensified by Bolsonaro’s forest policies.
Patagonia’s huemul is an agile herbivore of which only about 1,500 may remain at 100 or so scattered sites between sea level and the Andes; it is being buffeted by complex interrelated stressors.
