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.

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.

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.

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.

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.

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.

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.

If you were ever to see sewage sludge up close, you might be hard-pressed to find any redeemable value; however, researchers now see it another way.

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.

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.

Researchers have created a robot capable of conducting experiments more efficiently and sustainably to develop a range of new semiconductor materials with desirable attributes. The researchers have already demonstrated that the new technology, called RoboMapper, can rapidly identify new perovskite materials with improved stability and solar cell efficiency.

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.

Women with a history of endometriosis had higher concentrations of cadmium in their urine compared to those without that diagnosis, according to a new study that suggests the toxic metal could be linked to the development of endometriosis.

Scientists have found that competition between strains of beneficial bacteria in the soil degrades the service that the bacteria provide to their hosts.

Chemists have demonstrated that water remediation can be powered in part -- and perhaps even exclusively -- by renewable energy sources.

In Africa, climate change impacts are experienced as extreme events like drought and floods. It has now been possible to predict and monitor these climatic events, providing early warning of their impacts on agriculture to support humanitarian and resilience programming in the most food insecure countries of the world.

A large portion of Greenland was an ice-free tundra landscape -- perhaps covered by trees and roaming woolly mammoths -- in the recent geologic past (about 416,000 years ago), a new study shows. The results help overturn a previous view that much of the Greenland ice sheet persisted for most of the last two and a half million years. Instead, moderate warming, from 424,000 to 374,000 years ago, led to dramatic melting. At that time, the melting of Greenland caused at least five feet of sea level rise, despite atmospheric levels of heat-trapping carbon dioxide being far lower than today (280 vs. 420 ppm). This indicates that the ice sheet on Greenland may be more sensitive to human-caused climate change than previously understood -- and will be vulnerable to irreversible, rapid melting in coming centuries.
