Plastic pollution has rapidly escalated into a global environmental crisis that threatens ecosystem function and human health at an epic scale. Solutions are urgently needed, but while scientists, conservationists and more than 75 nations have called for binding limits on fossil fuel-driven plastic production, the plastics industry is opposed to all limits and is instead pushing a collection of technologies known as ‘chemical recycling.’ Critics say the industry is utilizing deceptive accounting practices and marketing jargon to rebrand polluting plastic incineration disposal methods. To date, chemical recycling facilities have created a relatively miniscule amount of recycled plastic, according to industry critics. But consumer product labels claiming “20% recycled plastic” have become an increasingly common sight on single-use plastic items. Reading such labels, consumers might logically assume that the product contains 20% recycled material, but that might not be the case. In addition, that potentially misleading label could be greenwashing environmentally damaging plastic incineration. Chemical recycling: Cutting-edge solution or sleight of hand? Chemical recycling, also dubbed ‘advanced recycling’ by the industry, uses chemicals, intense heat and/or pressure to break down plastic waste into its molecular building blocks. This contrasts with traditional ‘mechanical’ recycling methods which shred plastic waste into tiny flakes that can be melted and re-molded into new products. The most common form of chemical recycling, called ‘pyrolysis,’ uses high temperatures and pressure to convert waste plastic into an oil, which can be further processed into a variety of chemicals, some of which can be used to create new plastics.…This article was originally published on Mongabay

For more than two decades, National Geographic photographer Steve Winter and environmental journalist Sharon Guynup have followed big cats into some of Earth’s wildest, most dangerous places. Their work has taken them from the jungles of India and Brazil to the high Himalaya, from Southeast Asia’s forests to the African savanna and the urban wilds of Los Angeles, documenting the world’s big cats and the ways humans are succeeding or failing in living alongside them. Winter’s iconic photos of tigers, jaguars, snow leopards, cougars and lions have earned some of the field’s highest honors, including Wildlife Photographer of the Year. He is also known for his innovative use of remote camera traps, which has allowed him to capture intimate glimpses of animals that are extraordinarily difficult to observe in the wild.

Guynup, an award-winning environmental journalist, and now, Mongabay’s global wildlife editor, has penned prolific reporting on numerous topics. She’s especially known for her coverage of big cat conservation, exposés on wildlife trafficking, documenting the creation of wildlife corridors, and alerting the world to the threats posed by zoonotic diseases. The two have been partners in life and work for 37 years (they married just last year), and together have produced investigations delivering real change. Their reporting on captive tigers in the U.S., for example, (featuring Steve’s photos and Sharon’s prose), revealed abuse and wildlife trafficking, contributing to the passage of…This article was originally published on Mongabay

As frozen ground thaws in the Arctic, dead plants and animals locked in soils for thousands of years start to decay, releasing methane and carbon dioxide. Those gases trap heat from the sun and warm the planet. And the more the planet warms, the more Arctic permafrost thaws. This is just one feedback loop among many that most climate modeling has largely overlooked. A recent study published in the journal Environmental Research Letters examined four sources of greenhouse gases from natural systems: permafrost, wetlands, freshwater, and wildfires. The authors estimate that greenhouse gases released by these natural systems could add another 0.2°-0.4° Celsius (0.4°-0.7° Fahrenheit) of warming by 2100. That would amplify human-caused warming since 2020 by 20-30%. Methane accounts for roughly half that warming. Natural systems such as wetlands, permafrost, and forests have always released some greenhouse gases. This study tracks only the extra emissions released after 2020, as humanity keeps heating the planet by burning fossil fuels, clearing forests, and other activities. As this increased heat revs up these natural systems, thawing permafrost exposes additional ancient organic matter to decay. Warmer wetlands and freshwater lakes speed up the growth of the microbes that make methane. Drier forests burn more often, releasing planet-warming gases. The study was the first to pull all four sources together and “quantify this amplification of anthropogenic global warming,” lead author Sam Abernethy, a climate scientist at U.S.-based nonprofit Spark Climate Solutions, told Mongabay.

As a potentially historic El Niño builds in the Pacific, evidence suggests that climate change is ratcheting up the intensity of such events. And as temperatures rise in the future, the number and frequency of strong El Niños could increase even further, some experts say. “The evidence is accumulating that climate change makes for more powerful El Niños,” climate scientist Mark Cane with Columbia University in the U.S. told Mongabay in a video interview. His work was instrumental in enabling accurate forecasting of El Niño events in the late 1980s and early ’90s. This year’s El Niño is on the verge of breaking all records as it continues to build and is forecast to peak between October and December 2026, according to most models. A pre-print study found an event of this size is six times more likely due to climate change. The 2026-2027 event “is clearly going to be very large, up there with the handful of largest events that we’re aware of,” Cane said. A coral reef in the Galapagos Islands. In 1982, a marine heatwave triggered by a very strong El Niño killed off around 95% of the coral in the Galapagos. That left “death horizons” in the coral samples, evidence of the catastrophic impact of that event. Image by Julia Cole. A continuing debate Whether climate change is intensifying El Niños and altering their frequency — and crucially, whether it will continue to do so — remains an open question. Today’s El Niños can be forecast…This article was originally published on Mongabay
