Extinct offshore volcano could store gigatons of carbon dioxide      (via sciencedaily.com)     Original source 

A new study concludes that an extinct volcano off the shore of Portugal could store as much as 1.2-8.6 gigatons of carbon dioxide, the equivalent of ~24-125 years of the country's industrial emissions. For context, in 2022 a total of 42.6 megatons (0.0426 gigatons) of carbon dioxide was removed from the atmosphere by international carbon capture and storage efforts, according to the Global CCS Institute. The new study suggests that carbon capture and storage in offshore underwater volcanoes could be a promising new direction for removal and storage of much larger volumes of the greenhouse gas from the atmosphere.

Researchers examine cooling power plants with brackish groundwater      (via sciencedaily.com)     Original source 

Nontraditional water sources can be deployed to help cope with climate-induced water risks and tackle the increasing water demand for decarbonization of fossil fuel-fired power plants, but that could increase the cost of electricity generation by 8 percent to 10 percent.

Coastal ecosystems are a net greenhouse gas sink, new research shows      (via sciencedaily.com)     Original source 

A new greenhouse gas budget shows coastal ecosystems globally are a net greenhouse gas sink for carbon dioxide (CO2) but emissions of methane (CH4) and nitrous oxide (N2O) counteract some of the CO2 uptake, according to researchers.

How a drought affects trees depends on what's been holding them back      (via sciencedaily.com)     Original source 

Droughts can be good for trees. Certain trees, that is. Contrary to expectation, sometimes a record-breaking drought can increase tree growth. Why and where this happens is the subject of a new article.

Fine particulate matter catalyzes oxidative stress in the lungs      (via sciencedaily.com)     Original source 

Study sheds new light on the adverse health effects of air pollution: hydrogen peroxide production of fine particles may not be as important as previously assumed. A new study reveals that the adverse health effects of fine particulate matter (PM2.5) are attributable to the conversion of peroxides into more reactive species such as the hydroxyl radical (OH) rather than the direct chemical production of hydrogen peroxide (H2O2) as previously thought.

Eruption of Tonga underwater volcano found to disrupt satellite signals halfway around the world      (via sciencedaily.com)     Original source 

Researchers found that the Hunga-Tonga eruption was associated with the formation of an equatorial plasma bubble in the ionosphere, a phenomenon associated with disruption of satellite-based communications. Their findings also suggest that a long-held atmospheric model should be revised.

Earlier snowpack melt in Western US could bring summer water scarcity      (via sciencedaily.com)     Original source 

Mountain snowpack, typically seen as the water tower of the Western United States and Canada, is in decline, according to a new study. Researchers created the Snow Storage Index to assess snow water storage from 1950-2013 and found that storage has significantly declined in more than 25% of the Mountain West, in part because more snow is melting during winter and spring.

Even slight traffic noise has a negative impact on work performance      (via sciencedaily.com)     Original source 

As cities are densified at a fast pace, there is now construction very close to roads and thoroughfares. It is already known that noise can have a negative impact on human health, but new research shows that as little as 40 decibels of traffic noise -- the typical level of background noise in an office environment or kitchen -- has a detrimental effect on cognitive performance.

In years after El Niño, global economy loses trillions      (via sciencedaily.com)     Original source 

Researchers report that the financial toll of the climate pattern known as El Niño can persist for several years and cost trillions in lost income worldwide. The study, which is among the first to evaluate the long-term costs of El Niño, found that the 1982 and 1997 events led to $4.1 trillion and $5.7 trillion in lost income in the five years following them. With El Niño projected to return this year, the researchers project that global economic losses for the 21st century will amount to $84 trillion as climate change potentially amplifies the events' frequency and strength.

Half of world's largest lakes losing water      (via sciencedaily.com)     Original source 

Fifty-three percent of the world's largest freshwater lakes are in decline, storing less water than they did three decades ago, according to a new study. The study analyzed satellite observations dating back decades to measure changes in water levels in nearly 2,000 of the world's biggest lakes and reservoirs. It found that climate change, human consumption and sedimentation are responsible.
