Our pollution of the planet with heavy metals, plastics, industrial chemicals, pesticides and more is pushing Earth systems to the limit, and us closer to crossing a dangerous planetary boundary we don’t understand.
Industrial agriculture feeds billions of people and created the modern world. But the nitrogen and phosphorus it’s fertilized with is putting the biosphere, and humanity, at risk.
All seven sea turtle species are already endangered. Now humanity’s overshoot of planetary boundaries — climate change, ocean acidification, pollution and more — is upping the ante. Can turtles, people and conservation adapt?
As bad as the climate crisis now unfolding appears to be, things could have been even worse, with the world a much less hospitable place for human life. What has…
Water-sensitive urban design (WSUD), a holistic sustainable approach to water management, could give the world’s cities a viable means of dealing with the climatic shocks ahead. Cape Town and Singapore point the way.
Is harnessing the storage power of soils the global carbon solution we have been searching for? Understanding soil-formation and function is a first step to finding out.
A huge debate has raged among climate modelers for decades as to how climate change will alter clouds, making Earth cooler or warmer. New research using a machine learning model agrees with the majority view: Clouds will make for a warmer world.
In May 2020, Shivaprakash Nagaraju, senior scientist at The Nature Conservancy in India, was working in New Delhi when he contracted COVID-19. “I had breathing problems and other symptoms, and…
Record extreme weather in the U.S., Brazil, China and elsewhere is impacting food production this year, with the future expected to be far worse. Agriculture requires “transformational change” to meet the climate crisis, say experts.
The new, more contagious COVID-19 Delta variant is raging worldwide, while new pandemics are emerging at an ever-faster rate. But we’re still not taking the urgent action needed to prevent the next zoonotic disease outbreak, experts say.
New agri-technologies and traditional farming practices done right could combine to offer significant benefits and hope for the global environment and health.
With wildfires raging in the western U.S. and floods sweeping parts of Europe, it’s easy to forget that these regions are some of the most well-prepared to tackle climate change.…
In late June, Portland, Oregon, experienced its hottest day on record, reaching 42° Celsius (108° Fahrenheit). The last time it had been this hot was in 1981, when temperatures soared…
A new study has identified 2050 as the tipping point by which stakeholders in the Mekong Delta will no longer be able to mitigate the issue of saltwater intrusion, which…
Researchers are seeking to pinpoint climate change “tipping points,” but defining what that means exactly, when it will come, and what makes it happen, is unimaginably difficult when faced with the chaotic complexities of a vast Earth biome.
Sea ice fell to its lowest extent on record for this time of year, while new studies find Arctic coastal ice may be receding 70-110% faster than thought, winter ice is failing to regrow fully, and last multi-year ice refuge is under assault.
When the first tile in a line of dominoes tips forward, it affects everything in front of it. One after another, lined-up dominoes knock into each other and topple. This…
SINGAPORE — Singapore is launching a carbon trading marketplace focused on nature conservancy projects, a move that could protect at-risk tropical forests in the region while unlocking a ready source…
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…
Growing up in Sweden, environmental scientist Johan Rockström always knew the southern of the two peaks of Mount Kebnekaise was the highest point in the country. But thanks to climate…
To stay within planetary boundary safe limits, we must protect soils by conserving global habitat and revamping industrial agribusiness — and do it fast.
Tropical forests around the world are being destroyed at an alarming rate, even in 2020 when the global economy slowed dramatically during the pandemic. A new report released this week…
The United Nations Basel Convention regulates international transport of hazardous waste, which in 2021 expanded to include plastics. But the U.S. has never fully implemented the agreement; Biden may change that.
Created in 1987, the pathbreaking treaty not only phased down scores of ozone depleting chemicals and is helping heal the ozone hole — it also offers a flexible, regularly updating example for future environmental treaties.
From Tripoli to Phoenix, the world’s thirst in great desert cities is deepening, even as agribusiness guzzles more water to feed them. Humanity’s arid urban places are colliding with a key Planetary Boundary, scientists warn.
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.…
Some 100 ozone-depleting CFCs and HCFCs are being phased out by the landmark treaty, but can this evolving accord now save Earth from the HFCs — one of which is a greenhouse gas 12,700 more potent than carbon dioxide.
Polar phytoplankton, fish, seabirds and mammals are increasingly threatened by global warming, which is destabilizing Arctic ecosystems, even as southern species move northward — will the imbalanced biome collapse?
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.
