New Yorkers can apparently breathe a sigh of relief, at least for now. Their exposure to the smoke in June 2023 from Canadian wildfires led to only a slightly higher bump in visits to New York City hospital emergency departments for breathing problems or asthma attacks than what is seen on days when pollen counts are high. However, authors of a new study say other possible health effects, such as possible heart attacks and stroke, still need to be investigated.

A new study finds rivers and streams at higher latitudes contributing as much methane, a potent greenhouse gas, to the atmosphere as warmer waters in the tropics. The surrounding habitat, not temperature, is the important driver of methane emissions. The findings could improve methane estimates and models of climate change, and point to land-management changes and restoration opportunities that can reduce the amount of methane escaping into the atmosphere.

Household fruit and vegetable production, in allotments and gardens, could be key to a healthy and food-secure population, a new study has found.

A shipping container that can test passive cooling systems could help researchers and builders find carbon-free ways to keep people cool in extreme temperatures. Researchers created the 60 square-foot chamber to test passive systems that use wind towers along with water evaporation instead of electricity to cool spaces.

The entire contiguous U.S. has experienced massive urban expansions and the Atlantic Coast shows outstandingly high rates. Urban expansion has substantially squeezed the space of tidal flats and affected surrounding environments. In new urban areas, tidal flats have undergone considerable degeneration with more significant patterns as they get closer to new urban locations. Tidal flats protect against the ocean's destructive powers such as hurricanes. Without some inland spaces to move around, they will likely disappear, which will have dire consequences for beachfront communities.

The world needs greener ways to make chemicals. In a new study, researchers demonstrate one potential path toward this goal by adapting hydrogen fuel cell technologies.

A new study shows that water underneath glaciers may surge due to thinning ice sheets -- a dangerous feedback cycle that could increase glacial melt, sea level rise, and biological disturbances.

Applying ground-up silicate rock to Midwestern farm fields can capture significant amounts of carbon dioxide and prevent it from accumulating in the atmosphere, according to a new study that successfully quantified those climate benefits for the first time.

New research reveals a promising breakthrough in green energy: an electrolyzer device capable of converting carbon dioxide into propane in a manner that is both scalable and economically viable.

The US has committed to reaching net-zero emissions by 2050. To accomplish this goal, large cuts in emissions are necessary, especially in high-emission sectors like the building industry. Researchers use a computational model to analyze several scenarios of future building energy use in the US. They find that by tackling emissions on multiple fronts and placing focus on 'demand-side measures' that affect how power is drawn from the grid, such as technologies like electric heat pumps and smart thermostats, the US can achieve its climate goals, decrease building emissions by 91% from their 2005 peak, and save over $100 billion each year on energy costs.

A study has demonstrated that the partial substitution of red and processed meat with pea- and faba bean -- based food products ensured sufficient intake of amino acids in the diet and did not negatively affect bone metabolism.

The economists say more frequent use of up-front experiments would result in more effective environmental policymaking in areas ranging from pollution control to timber harvesting across the world.

Conventional wisdom among ecologists holds that the more species there are inhabiting an ecosystem, the less vulnerable any one species will be to a threat like a parasite. A new study of tadpoles illustrates how overlapping biological and environmental factors can complicate how we value protecting diverse animal communities. The researchers found that environmental pollutants like road salt influence whether increased biodiversity helps or hinders disease outbreaks in wildlife, which can complicate how we value protecting diverse animal communities.

Research attempts to quantify the value of U.S. property at risk in forested areas exposed to increased ecological disturbance associated with climate change, such as wildfire and tree mortality. Property exposed to such climate risks, especially in California, is project to climb substantially if emission-reduction measures are not taken.

A new study reveals that the wealthiest Americans, those whose income places them in the top 10% of earners, are responsible for 40% of the nation's total greenhouse gas emissions. The study links income, especially income derived from financial investments, to the emissions used in generating that income. The authors suggest that policymakers adopt taxes focused on shareholders and the carbon intensity of investment incomes in order to equitably meet the goal of keeping the global temperature to 1.5 C of warming.

Humans have a positive view of nature. But is this due to an approach we have learned while growing up, or is it something we are born with? The answer is 'Both', according to researchers.

The in-depth analysis reveals how local tidal currents strongly affect the movement of sea ice in the Arctic ocean and provides an unprecedented look at how the makeup of the seafloor is causing some of the most abrupt changes.

Human-caused climate change is shortening the snow cover period in the Arctic. But according to new research led by Earth system scientists, some parts of the Arctic are getting deeper snowpack than normal, and that deep snow is driving the thawing of long-frozen permafrost carbon reserves and leading to increased emissions of greenhouse gasses like carbon dioxide and methane.

Researchers have demonstrated the use of a specially coated metal mesh to harvest water from fog and simultaneously remove pollutants. People living in foggy areas with low rainfall should benefit from this technology.

Could plants be the answer to the looming threat of microplastic pollution? Scientists found that if you add tannins (natural plant compounds that make your mouth pucker if you bite into an unripe fruit) to a layer of wood dust, you can create a filter that can trap virtually all microplastic particles present in water. While the experiment remains a lab set-up at this stage, the team is convinced that the solution can be scaled up easily and inexpensively.
