Three Gorges Dam: Friend or foe of riverine greenhouse gases?
Dams are conventionally regarded as emitters of GHGs in large rivers. A team from Peking University of China, however, has disrupted this perception, based on whole system thinking applied to the Three Gorges Dam (TGD) on the Yangtze River in China......»»
Study finds global carbon markets overcredit cookstove greenhouse gas reductions by a factor of 10
The fastest growing type of offset on the global carbon market subsidizes the distribution of efficient cookstoves in developing countries to reduce greenhouse gas emissions, but a new study finds that the credits overestimate the stoves' carbon savi.....»»
Researchers develop high-efficiency carbon dioxide electroreduction system for reducing carbon footprint
Global warming continues to pose a threat to human society and ecological systems, and carbon dioxide accounts for the largest proportion of the greenhouse gases that dominate climate warming......»»
Climate models predict weakened subtropical circulation in stable warming scenario
The latest climate models show a weakening of the subtropical circulation under stable greenhouse warming scenario, according to a new study published in Nature Communications......»»
What"s stopping US climate policies from working effectively?
In an effort to reduce greenhouse gas emissions and curb global warming, the U.S. has enacted several ambitious federal laws, such as the Inflation Reduction Act (IRA) passed in 2022 and the Infrastructure Investment and Jobs Act (IIJA) of 2021......»»
A path to achieve a net-zero greenhouse gas economy
Anew report co-authored by 68 scientists from more than a dozen institutions—including the University of Pennsylvania—offers a first-of-its-kind high-resolution assessment of carbon dioxide (CO2) removal (CDR) in the United States......»»
Team upgrades technology for monitoring methane emissions
Researchers at the National Institute of Standards and Technology (NIST) have upgraded a highly precise technology designed to monitor emissions of methane, a critical greenhouse gas, and other trace gases, even in harsh field conditions. Measuring m.....»»
Advanced hour-hectometer hyperspectral remote sensing for fine-scale atmospheric emissions
A groundbreaking study by researchers from a number of institutions in China introduces a novel hyperspectral remote sensing technique capable of hour-hectometer level horizontal distribution of trace gases, offering an advanced tool to accurately id.....»»
U.S. Emissions Fell by 2 Percent in 2023, Even as Economy Grew
Collapsing coal use drove a reduction in overall U.S. greenhouse gas emissions, but transportation emissions are still on the rise.....»»
Social scientist: While providing help inspires others, people would rather help a family member than a neighbor
Doing the shopping for a neighbor, driving a friend to an appointment, helping an aunt with the garden: there are plenty of people who occasionally provide a little assistance. In her Ph.D. thesis, Marlou Ramaekers has shown that while providing help.....»»
Mating anchovies stir up the sea as much as a major storm—and it"s good for the environment, too
Why would oceanographers ever care about anchovies having sex? We do because these small fish can help mix different layers of the ocean when they mate. This circulates nutrients, oxygen, and greenhouse gases around different layers of the ocean, the.....»»
Carbon pollution is down in the US, but not fast enough to meet Biden"s 2030 goal, new report says
Climate-altering pollution from greenhouse gases declined by nearly 2% in the United States in 2023, even as the economy expanded at a faster clip, a new report finds......»»
Why we need to know more about individual carbon footprints
Most countries, including Switzerland, record their greenhouse gas emissions by source and sector. In absolute terms, Swiss greenhouse gases make up less than 1% of global emissions. With an average of 12 metric tons of CO2 equivalents per capita per.....»»
Uncertainty abounds in seeding the sky to fight climate change, says study
As greenhouse gas levels increase in Earth's atmosphere, scientists are considering ways to temporarily limit rising temperatures. One idea is to inject aerosols into the stratosphere to reflect incoming sunlight, thereby reducing global warming and.....»»
Process for the optical analysis of trace gases optimized
Laser-based absorption spectroscopy is an important method for determining the concentration of gas components in a sample. Modern devices are highly specialized for detecting very specific gases, such as trace gases in the atmosphere, in combustion.....»»
Secrets of a hot Saturn and its spotted star unlocked
A team of astronomers including McGill Professor Nicolas Cowan has unraveled the enigmatic atmosphere of the exoplanet HAT-P-18 b, shedding light on its intriguing blend of gases, clouds, and even the effects of its star's activity.....»»
Researchers develop Mexico"s first comprehensive greenhouse gas budget
Mexico's greenhouse gas emissions are the second highest among Latin American countries, trailing only Brazil according to the World Bank. But until now, no one had leveraged the full spectrum of available scientific data to make an estimate of sourc.....»»
Research aims to convert greenhouse gas into valuable products with electricity
Researchers at Case Western Reserve University are developing ways to convert waste into fuels and other products, using processes that are energy efficient and powered by renewable sources......»»
An emergency brake for the climate: EU advisory board recommends 90%–95% reduction in emissions by 2040
To limit global warming to 1.5°, the EU's Science Advisory Board on Climate Change recommends that Europe reduce its greenhouse gas emissions by 90%–95% by 2040 compared to 1990. Fossil fuels should be phased out as quickly as possible......»»
Did You Buy a New Phone This Year?
There aren’t many days left in 2023, so to reflect on parts of the year we wanted to get personal with you. We want to know, dear friend, if you bought a new phone this year. And after you answer that – assuming you said “yes”.....»»
