North Atlantic 'Achilles heel' lets upper atmosphere affect the abyss
A University of Utah study suggests something amazing: Periodic changes in winds 15 to 30 miles high in the stratosphere influence the seas by striking a vulnerable "Achilles heel" in the North Atlantic and ...
The new normal? Record-breaking 2011 Lake Erie algae bloom may be sign of things to come
The largest harmful algae bloom in Lake Erie's recorded history was likely caused by the confluence of changing farming practices and weather conditions that are expected to become more common in the future ...
Earth still absorbing about half carbon dioxide emissions produced by people: study
Earth's oceans, forests and other ecosystems continue to soak up about half the carbon dioxide emitted into the atmosphere by human activities, even as those emissions have increased, according to a study ...
Ocean's carbon dioxide uptake reduced by climate change
(PhysOrg.com) -- How deep is the ocean's capacity to buffer against climate change? As one of the planet's largest single carbon absorbers, the ocean takes up roughly one-third of all human carbon emissions, ...

Insoluble dust particles can form cloud droplets affecting global and regional climates
New information on the role of insoluble dust particles in forming cloud droplets could improve the accuracy of regional climate models, especially in areas of the world that have significant amounts of mineral ...
Report: Direct removal of carbon dioxide from air likely not viable
Technologies for removing carbon dioxide from the atmosphere are unlikely to offer an economically feasible way to slow human-driven climate change for several decades, according to a report issued by the American Physical ...
Long-term warming likely to be significant despite recent slowdown
A new NASA study shows Earth's climate likely will continue to warm during this century on track with previous estimates, despite the recent slowdown in the rate of global warming.
Link between air pollution and cyclone intensity in Arabian Sea
Pollution is making Arabian Sea cyclones more intense, according to a study in this week's issue of the journal Nature.
Going to Earth's core for climate insights
(PhysOrg.com) -- The latest evidence of the dominant role humans play in changing Earth's climate comes not from observations of Earth's ocean, atmosphere or land surface, but from deep within its molten core.
Greenhouse gas level highest in two million years, NOAA reports (Update 2)
Worldwide levels of the greenhouse gas that plays the biggest role in global warming have reached their highest level in almost 2 million years—an amount never before encountered by humans, U.S. scientists ...

Study shows how sea otters can reduce CO2 in the atmosphere
(Phys.org)—Can an abundance of sea otters help reverse a principal cause of global warming?
Weather extremes provoked by trapping of giant waves in atmosphere
The world has suffered from severe regional weather extremes in recent years, such as the heat wave in the United States in 2011 or the one in Russia 2010 coinciding with the unprecedented Pakistan flood. ...
