Scientists at Los Alamos National Laboratory have developed a computer model that clarifies the complex processes driving ocean mixing in the vast eddies that swirl across hundreds of miles of open ocean.
In this one-minute video, hear from an expert in water sustainability regarding the economic and social challenges of water purification and reuse. Are these challenges holding back the potential of modern water technology?
Daily weather patterns have changed in recent decades, making eastern North America, Europe and western Asia more prone to nastier summer heatwaves that go beyond global warming, a new study finds. A team of climate scientists at Stanford Univ. looked at weather patterns since 1979 and found changes in frequency and strength in parts of the world.
In this one-minute video, hear from Nina Fedoroff, the former Science and Technology advisor to U.S. Secretaries of State Condoleezza Rice and Hillary Clinton, on why she blames intense regulatory demands for the lack of nutritionally valuable GMOs.
Some top international doctors and public health experts have issued an urgent prescription for a feverish planet Earth: Get off coal as soon as possible. Substituting cleaner energy worldwide for coal will reduce air pollution and give Earth a better chance at avoiding dangerous climate change, recommended a global health commission.
Over billions of years, the total carbon content of the outer part of the Earth has gradually increased, scientists reported in the Proceedings of the National Academy of Sciences. Craig Manning, a professor of geology and geochemistry at UCLA, and Peter Kelemen, a geochemistry professor at Columbia Univ., present new analyses that represent an important advance in refining our understanding of Earth's deep carbon cycle.
In a study that contradicts the received wisdom on health impacts of climate change, scientists say that we shouldn’t expect substantial reduction in winter deaths as a result of global warming. This new research is published in Environmental Research Letters.
NASA says an international satellite studying the world's oceans has stopped working after four years. The space agency said Wednesday that the Argentine-built satellite ceased operations last week after a hardware failure. The satellite carried a NASA instrument called Aquarius that measured the concentration of dissolved salt at the sea surface.
The problem is simple to understand. Molecules of carbon and other greenhouse gases absorb heat. The more greenhouse gases emitted into the atmosphere, the warmer the atmosphere becomes, exacerbating global climate change. Solving the problem is not so simple, especially with regards to aviation.
For the last decade, astronomers have observed curious “hotspots” on Saturn’s poles. In 2008, NASA’s Cassini spacecraft beamed back close-up images of these hotspots, revealing them to be immense cyclones, each as wide as the Earth. Scientists estimate that Saturn’s cyclones may whip up 300 mph winds, and likely have been churning for years.
How light of different colors is absorbed by carbon dioxide can now be accurately predicted using new calculations developed by a Univ. College London (UCL)-led team of scientists. This will help climate scientists studying Earth's greenhouse gas emissions to better interpret data collected from satellites and ground stations measuring carbon dioxide.
If you want to assign blame on an overcast day, then cast your eyes on the tropics. Water vapor originating is transported to midlatitudes on long filaments of flowing air that intermittently travel across the world’s oceans. When these airy tendrils make landfall, they can cause severe floods. Yet despite the importance of these “atmospheric rivers” for global water and heat cycles, the mechanism behind their formation is a mystery.
Variations in the amount of oxygen in Earth's atmosphere significantly altered global climate throughout the planet's history. Efforts to reconstruct past climates must include this previously overlooked factor, a new Univ. of Michigan-led study concludes. Oxygen currently comprises about 21% of Earth's atmosphere by volume but has varied between 10% and 35% over the past 541 million years.
As many of the world’s nations prepare and implement plans to cut greenhouse gas emissions, researchers say another critical factor needs to be considered. A new study has found for the first time that efforts to keep global temperatures in check will likely lead to more people going hungry. That risk, they say, doesn’t negate the need for mitigation but highlights the importance of comprehensive policies.
In a recently published study, a research team peels back the mysteries of the structures of tiny aerosol particles at the surface of the ocean. The work shows how the particles' chemical composition influences their abilities to take in moisture from the air, which indicates whether the particle will help to form a cloud, a key to many basic problems in climate prediction.
Northwestern Univ. scientists are experimenting with ways to eliminate a cancer-causing agent from gasoline by neutralizing the benzene compound found in gasoline. They developed a catalyst that effectively removed benzene from the other aromatic compounds in gasoline, making it cleaner and more efficient.
Modern mountain climbers typically carry tanks of oxygen to help them reach the summit. It’s the combination of physical exertion and lack of oxygen at high altitudes that creates one of the biggest challenges for mountaineers. Univ. of Washington researchers and collaborators have found that the same principle will apply to marine species under global warming.
China is expected this month to formally submit its pledge for a global climate treaty that countries are seeking to finalize by December, the United Nations' top adviser on climate change said Thursday. Chinese President Xi Jinping sent a letter to Ban Ki-moon last week about the issue, U.N. assistant secretary-general Janos Pasztor told The Associated Press. Pasztor did not give details.
Each summer, Greenland’s ice sheet begins to melt. Pockets of melting ice form hundreds of large, “supraglacial” lakes on the surface of the ice. Many of these lakes drain through cracks and crevasses in the ice sheet, creating a liquid layer over which massive chunks of ice can slide. This natural conveyor belt can speed ice toward the coast, where it eventually falls off into the sea.
Paleontologists have documented how dramatic shifts in climate have led to dramatic shifts in evolution. One such event, the Grande Coupure, was a wipeout of many European mammal species 33.9 million years ago when global temperatures and precipitation declined sharply. What has been puzzling is that during the same transition between the Eocene and Oligocene periods, North American mammals fared much better.
A Northwestern Univ. team has confirmed a new way to help the airline industry save dollars while also saving the environment. And the solution comes in three dimensions. By manufacturing aircrafts’ metal parts with 3D printing, airlines could save a significant amount of fuel, materials and other resources.
The heat generated by burning a fossil fuel is surpassed within a few months by the warming caused by the release of its carbon dioxide into the atmosphere, according to new work. The release of CO2 into the atmosphere contributes to the trapping of heat that would otherwise be emitted into outer space.
The remains of tiny creatures found deep inside a mountaintop glacier in Peru are clues to the local landscape more than a millennium ago, according to a new study. The unexpected discovery of diatoms, a type of algae, in ice cores pulled from the Quelccaya Summit Dome Glacier demonstrate that freshwater lakes or wetlands that currently exist at high elevations on or near the mountain were also there in earlier times.
Researchers trying to figure out what makes some hurricanes strengthen into catastrophic monsters have a new lab that allows them to generate tropical storm conditions with the flip of a switch. The lab is at the Univ. of Miami's Rosenstiel School of Marine and Atmospheric Science. It's known as the Surge-Structure-Atmosphere Interaction, or SUSTAIN.
A new study shows how huge influxes of fresh water into the North Atlantic Ocean from icebergs calving off North America during the last ice age had an unexpected effect—they increased the production of methane in the tropical wetlands. Usually increases in methane levels are linked to warming in the Northern Hemisphere, but scientists have identified rapid increases in methane during particularly cold intervals.
