Rising desertification shows we can"t keep farming with fossil fuels
Three-quarters of Earth's land has become drier since 1990. Droughts come and go—more often and more extreme with the incessant rise of greenhouse gas emissions over the last three decades—but burning fossil fuels is transforming our blue planet......»»
Tidal streams of interstellar objects may flow through the Milky Way like braided rivers
We know that interstellar objects occasionally visit our solar system. So far, we have only discovered two interstellar objects (ISOs), but that's mainly because we can only distinguish them from solar system bodies by their orbital motion, and that.....»»
One of world"s largest glacier floods triggered in Greenland
For the first time, scientists have observed the release of a massive glacial lake outburst in East Greenland, where more than 3,000 billion liters of meltwater were unleashed in just weeks. This rare, natural flooding event, witnessed by University.....»»
Researchers reveal key factors behind Japan"s plastic waste removal rates in rivers
Plastic pollution is an ever-growing problem in today's world, as most societies have become overly dependent on plastics for packaging, medical supplies, and general goods......»»
Study: Lake ice becoming unsafe, increasing drowning risk
Sports and recreational activities on frozen lakes across the Northern Hemisphere are a popular pastime for millions, but according to new research out of York University, the safety of that ice is becoming more precarious and shorter in duration......»»
Sink to source: Arctic is now emitting more carbon than it absorbs
After locking carbon dioxide in its frozen soil for millennia, the Arctic tundra is undergoing a dramatic transformation, driven by frequent wildfires that are turning it into a net source of carbon dioxide emissions, a US agency said Tuesday......»»
Ozone recovery delayed 17 years by feedstock emissions, old gear
A new study published in the journal Atmospheric Chemistry and Physics reveals a 17-year delay in the projected recovery of the ozone layer since 2006, underscoring the need for enhanced global environmental policies and enforcement......»»
A new global carbon trading market could be held hostage by speculators
Our planet's future hangs in the balance due to the unabated greenhouse gas emissions from burning fossil fuels. Treating these emissions as something that can be owned and exchanged in a market has been touted as a solution since the early 1990s, wh.....»»
Plans to stabilize Earth"s climate rely on emerging carbon removal technology—we need to get moving, say researchers
Global carbon emissions from fossil fuels continue to rise and 2024 is likely to be the world's hottest year on record......»»
Plankton study investigates how marine food webs respond to increasing alkalinity
The ocean naturally absorbs a quarter to a third of man-made CO2 emissions, but this process also leads to the acidification of seawater. By increasing the alkalinity of seawater through the addition of certain minerals (e.g., carbonates and silicate.....»»
Emissions from four Punjab district shows stubble burning leads to poorer health
Punjab is the epicenter of stubble burning in India. Although the majority of residents are aware of the harmful effects of burning crop waste, it is still a widespread practice, with serious consequences for health, household expenditures and the en.....»»
"Scary" drought empties one of Bosnia"s largest lakes
Staring across what was once one of Bosnia's largest expanses of water, all that Saliha Kuljanin can see is boats left high and dry after months of drought emptied Lake Jablanicko......»»
New catalyst can convert methane into useful polymers
Although it is less abundant than carbon dioxide, methane gas contributes disproportionately to global warming because it traps more heat in the atmosphere than carbon dioxide, due to its molecular structure......»»
X-ray vision: Seeing through the mystery of an X-ray emissions mechanism
Since the 1960s, scientists who study X-rays, lightning and similar phenomena have observed something curious: In lab experiments replicating these occurrences, electrons accelerated between two electrodes can be of a higher energy than the voltage a.....»»
Nationwide assessment finds urban areas face higher cancer risk from air pollution
New research builds on scientific understanding of how air pollution and cancer risk are distributed throughout the U.S. Air pollution, often resulting from industrial or vehicle emissions, can travel for hundreds of miles and impact the health of co.....»»
Swelling streams—climate change can cause more sediment in high-mountain rivers
Many high-mountain rivers in Asia transport more sediment downstream compared to a few years ago. Changes in sediment levels have a particularly strong impact on agriculture, water quality, flood management, and hydropower generation......»»
Warmer winters are fueling a growth in algal blooms across the Great Lakes
While commonly associated with the summer, algal blooms can also persist into the fall. As of late October 2024, blooms were still present along the southern shores of Lake Erie......»»
Stable perovskite catalyst achieves selective oxidation of light alkanes
Light alkanes are relatively simple molecules made entirely of carbon and hydrogen, arranged in linear or branching structures. Their oxidized counterparts, which include alcohols, epoxides, ketones, and aldehydes, are ubiquitous in the chemical indu.....»»
Clay minerals: Researchers observe for the first time how sediment particles align during deposition
Clay minerals are a major constituent of the Earth's surface and are mainly found in the sediments of lakes, rivers and oceans. The properties of clay and claystone depend on how the tiny sediment particles are orientated. Using the European Synchrot.....»»
