Making renewable, infinitely recyclable plastics using bacteria      (via sciencedaily.com)     Original source 

Scientists engineered microbes to make the ingredients for recyclable plastics -- replacing finite, polluting petrochemicals with sustainable alternatives. The new approach shows that renewable, recyclable plastics are not only possible, but also outperform those from petrochemicals.

New research method determines health impacts of heat and air quality      (via sciencedaily.com)     Original source 

The planet experienced the hottest day on record earlier this month and climate projections estimate the intensity of heat waves and poor air quality will increase and continue to cause severe impacts. Researchers have refined and expanded a method of data collection to assess their health impacts.

Climate change threatens 771 endangered plant and lichen species      (via sciencedaily.com)     Original source 

All plants and lichens listed as endangered under the Endangered Species Act are sensitive to climate change but there are few plans in place to address this threat directly, according to new research.

Delaying methane mitigation increases risk of breaching Paris Agreement climate goal, study finds      (via sciencedaily.com)     Original source 

A new study shows that efforts to reduce methane emissions are needed immediately if we are to meet global climate change goals. A key element of the 2015 Paris Agreement, a legally binding international treaty on climate change, is the commitment to limit average global temperatures increases to well below 2°C above pre-industrial levels, and pursue efforts to limit global warming to 1.5°C above pre-industrial levels. This requires reaching net-zero CO2 emissions by or around 2050 -- and deep reductions in methane and other emissions.

Earlier and earlier high-Arctic spring replaced by 'extreme year-to-year variation'      (via sciencedaily.com)     Original source 

About 15 years ago, researchers reported that the timing of spring in high-Arctic Greenland had advanced at some of the fastest rates of change ever seen anywhere in the world. But, according to new evidence, that earlier pattern has since been completely erased. Instead of coming earlier and earlier, it seems the timing of Arctic spring is now driven by tremendous climate variability with drastic differences from one year to the next.

Dune restoration could increase the resilience of Southern California's urban beaches to sea level rise      (via sciencedaily.com)     Original source 

Over the last several years, the residents of Santa Monica, a coastal city on the edge of Los Angeles, saw something neither they, their parents, or perhaps even their grandparents had ever seen before: a three-foot-tall dune system rising gently from the flat, groomed expanse of one of the world's most famous urban beaches. It's a six year alliance between sand, wind and vegetation, and, according to researchers, it's one way to enlist nature to help protect the coast from the impacts of climate change.

Arctic terns may navigate climate dangers      (via sciencedaily.com)     Original source 

Arctic terns -- which fly on the longest migrations of any animal on Earth -- may be able to navigate the dangers posed by climate change, new research suggests.

Soil microbes help plants cope with drought, but not how scientists thought      (via sciencedaily.com)     Original source 

In a multi-generation experiment, researchers found microbes helped plants cope with drought, but not in response to plants' cries for help. Instead, the environment itself selected for drought-tolerant microbes. And while those hardy microbes were doing their thing, they just happened to make plants more drought-tolerant, too.

Gloomy climate calculation: Scientists predict a collapse of the Atlantic ocean current to happen mid-century      (via sciencedaily.com)     Original source 

Important ocean currents that redistribute heat, cold and precipitation between the tropics and the northernmost parts of the Atlantic region will shut down around the year 2060 if current greenhouse gas emissions persist. This is the conclusion based on new calculations that contradict the latest report from the IPCC.

Dynamic pricing superior to organic waste bans in preventing climate change      (via sciencedaily.com)     Original source 

While composting and organic waste ban policies are gaining popularity across the United States, a new study finds dynamic pricing could be the most effective way for grocery chains to keep perishables out of landfills, reducing food waste by 21% or more.

Improving recyclable waste classification with laser-induced breakdown spectroscopy      (via sciencedaily.com)     Original source 

Delving into the intricacies of waste management, researchers explore the application of laser-induced breakdown spectroscopy technology for the identification and classification of recyclable waste. They collected and analyzed the spectra of 80 recyclable waste samples, classifying them into paper, plastic, glass, metal, textile, and wood based on LIBS spectra. This crucial step toward waste management optimization demonstrates a significant stride toward improving environmental sustainability and promoting resource reuse.

Scientists discover new isopod species in the Florida Keys      (via sciencedaily.com)     Original source 

Scientists have discovered a new species of marine cryptofauna in the Florida Keys. Cryptofauna are the tiny, hidden, organisms that make up the majority of biodiversity in the ocean. The tiny crustaceans are the first new gnathiid isopod to be discovered from the Floridian ecoregion in 100 years and are named after singer-songwriter Jimmy Buffett.

Risk of fatal heart attack may double in heat wave and high fine particulate pollution days      (via sciencedaily.com)     Original source 

An analysis of more than 202,000 heart attack deaths between 2015-2020 in a single Chinese province found that days that had extreme heat, extreme cold or high levels of fine particulate matter (PM2.5) air pollution were significantly associated with the risk of death from a heart attack, especially in women and older adults.
