A new approach to assessing policies in the climate crisis
Abruptly melting ice sheets, the collapse of coral reefs and rainforests: nature is complex—and climate policy must consider physical "tipping points" as well as uncertainties and measurement problems. How can the fight against the greenhouse effec.....»»
How well toxic elements leach out of coal ash depends on the ash"s nanoscale composition, shows study
Everyone knows that burning coal causes air pollution that is harmful to the climate and human health. But the ash left over can often be harmful as well......»»
Researchers advance DNA nanostructure stability
Researchers at the University at Albany's RNA Institute have demonstrated a new approach to DNA nanostructure assembly that does not require magnesium. The method improves the biostability of the structures, making them more useful and reliable in a.....»»
Elastocaloric cooling system opens door to climate-friendly AC
Air conditioning, refrigeration, and other cooling technologies account for more than 20 percent of today's global energy consumption, while the refrigerants they use have a global warming potential thousands of times greater than carbon dioxide. In.....»»
Unraveling the historic journey of the mung bean: A tale of evolution, migration and climate adaptation
The mung bean, commonly known as green gram, has played a pivotal role as a cheap protein source in regions where access to meat is limited. Spanning over 4,500 years, the cultivation of this humble legume has sustained civilizations throughout its h.....»»
"Heat highways" could keep electronics cool
As smart electronic devices become smaller and more powerful, they can generate a lot of heat, leading to slower processing times and sudden shutdowns. Now, as reported in ACS Applied Nano Materials, researchers have used an electrospinning approach.....»»
Using social media cherry blossom images and AI to track climate patterns
New research by Monash University experts has tracked Japanese hanami (flower viewing) via social media images, producing an unprecedented map of cherry blossoms across Japan to document their annual bloom and calculate its peak in major cities......»»
Illinois environmentalists push for state action to protect wetlands after Supreme Court ruling rolls back federal rules
Across the country, marshes, swamps and bogs quietly soak up flood water and filter pollutants. Ecologists agree they are one of the best natural defenses against climate change......»»
Study models geomagnetic field shielding over the last 100,000 years
New models of how the geomagnetic field that shields the Earth's atmosphere from cosmic rays has changed over tens of thousands of years can help us understand how the climate has changed over a similar timescale......»»
Researchers create tool to improve the forecasting of extreme rain events
Driven by global warming, the emerging climate crisis has in recent years included a rise in the frequency and intensity of extreme rain events, leading to loss of life and of property. A new research study, led by Dr. Assaf Hochman and by doctoral s.....»»
Researchers develop stepwise strategy for carbon dioxide reduction to multicarbon products
Though efficient C2+ production from CO2 electrocatalytic reduction reaction (CO2ERR) has become a promising approach to mitigate CO2 emissions and store intermittent renewable energy, it suffers from low selectivity and undesired side reactions......»»
Climate change has a dramatic impact on the global water cycle, say researchers
For Christoph Schär, ETH Zurich's Professor of Climate and Water Cycle, "global warming" is not quite accurate when it comes to describing the driver of climate change. "A better term would be 'climate humidification,'" he explains. "Most of the sol.....»»
Climate: Battle lines harden over how to slash CO2
Banish fossil fuels, capture their emissions, pull CO2 from thin air—diplomats in Bonn for UN-led climate talks agree there's too much planet-warming carbon dioxide in the atmosphere, but remain at loggerheads on the best way to reduce it......»»
How cats and dogs affect the climate—and what you can do about it
According to Patrick Hanson, the CEO of Luxaviation, a Luxembourg-based luxury airline firm, having pets can be just as polluting as traveling by private jet. In defense of his own industry, he declared recently that one of his company's customers pr.....»»
UN climate chief hails "unique insights" of embattled COP28 head
The UN's top climate official hailed the "unique insight" of a UAE oil executive whose naming as president of the key COP28 climate summit has outraged advocates and experts......»»
TSMC: advanced packaging demand surpasses current capacity, expansion is speeding up
TSMC held its shareholders' meeting today, where chairman Mark Liu stated that the company has faced various global challenges in recent years, including the US-China trade war, climate change, the pandemic, and the Russia-Ukraine war. However, Liu n.....»»
Pond emission measurements improve climate predictions
There could be billions of shallow lakes and ponds on Earth, though lack of mapping systems makes it hard to know just how many exist. Together, they emit significant amounts of greenhouse gases into the atmosphere, but emissions from these systems v.....»»
7 in 10 pupils want an education that helps them tackle the climate crisis, finds UK report
Secondary school pupils feel the climate change education they receive is too focused on passing exams and doesn't equip them with the skills they need to tackle the climate crisis, according to a new report......»»
When Not to Treat Cancer
Taking a rational and statistical approach to a diagnosis can lead to better choices about treatment—which in some cases might mean not treating cancer at all......»»
Climate justice: Global North owes $170 trillion for excessive carbon dioxide emissions, says study
Industrialized nations responsible for excessive levels of carbon dioxide emissions could be liable to pay a total of $170 trillion in compensation or reparations by 2050 to ensure climate change targets are met, say researchers......»»
Study: Climate change"s cost includes losses of learning and earnings due to natural disasters
In the wake of natural disasters, survivors' losses of education and lifetime earnings may be comparable to the cost of property damage, according to a new study in Nature Human Behaviour co-authored by R. Jisung Park, an assistant professor at Penn'.....»»
