2014 Antarctic ozone hole holds steady
The Antarctic ozone hole reached its annual peak size on Sept. 11, according to scientists from NASA and the National Oceanic and Atmospheric Administration. The size of this year's hole was 24.1 million square kilometers (9.3 million square miles) -- an area roughly the size of North America.

They know the drill: UW leads the league in boring through ice sheets
Hollow coring drills designed and managed by UW-Madison's Ice Drilling Design and Operations program are used to extract ice cores that can analyze the past atmosphere. Shaun Marcott, an assistant professor of geoscience at UW-Madison, was the first author of a paper published today in the journal Nature documenting carbon dioxide in the atmosphere between 23,000 and 9,000 years ago, based on data from an 11,000-foot hole in Antarctica.

New study shows 3 abrupt pulse of CO2 during last deglaciation
A new study shows that the rise of atmospheric carbon dioxide that contributed to the end of the last ice age more than 10,000 years ago did not occur gradually, but was characterized by three 'pulses' in which C02 rose abruptly.

Glacier song
Mountain glaciers represent one of the largest repositories of fresh water in alpine regions. However, little is known about the processes by which water moves through these systems. In this study published in Geology on 24 Oct. 2014, David S. Heeszel and colleagues use seismic recordings collected near Lake Gornersee in the Swiss Alps to look for signs of water moving through fractures near the glacier bed.

Icelandic volcano sits on massive magma hot spot
New research from University of California Davis and Aarhus University in Denmark shows that high mantle temperatures miles beneath the Earth's surface are essential for generating large amounts of magma. In fact, the scientists found that Iceland's Bardarbunga volcano lies directly above the hottest portion of the North Atlantic mantle plume.

NASA HS3 mission Global Hawk's bullseye in Hurricane Edouard
NASA's Hurricane Severe Storms Sentinel or HS3 mission flew the unmanned Global Hawk aircraft on two missions between Sept. 11 and 15 into Hurricane Edouard and scored a bullseye by gathering information in the eye of the strengthening storm. Scientists saw how upper-level wind shear was affecting Edouard on the HS3's Global Hawk flight of the 2014 campaign over Sept. 11 and 12, and saw the hurricane strengthen during the sixth flight on Sept. 15 and 16.

Researchers resolve the Karakoram glacier anomaly, a cold case of climate science
Researchers from Princeton University and other institutions may have hit upon an answer to a climate-change puzzle that has eluded scientists for years, namely why glaciers in the Karakoram range of the Himalayas have remained stable and even increased in mass while glaciers nearby and worldwide have been receding. Understanding the 'Karakoram anomaly' could help gauge the future availability of water for hundreds of millions of people.

Recently discovered microbe is key player in climate change
Scientists have discovered how an invisible menagerie of microbes in permafrost soils acts as global drivers of Earth processes such as climate via gas exchange between soils and the atmosphere. These findings will help climate modelers more accurately predict Earth's future climate.

Mediterranean, semi-arid ecosystems prove resistant to climate change
Climate change predictions for the Middle East, like other arid regions of the world, are alarming. But in testing these dire predictions, Tel Aviv University ecologists found that, contrary to expectations, no measurable changes in annual vegetation could be seen. None of the crucial vegetation characteristics -- neither species richness and composition, nor density and biomass -- had changed appreciably in the course of the rainfall manipulations.

NASA is carrying out its sixth consecutive year of Operation IceBridge research flights over Antarctica to study changes in the continent's ice sheet, glaciers and sea ice. This year's airborne campaign, which began its first flight Thursday morning, will revisit a section of the Antarctic ice sheet that recently was found to be in irreversible decline.

Scientists find ancient mountains that fed early life
Scientists have found a huge mountain range in Gondwana, 600 million years ago. It ran from modern west Africa to northeast Brazil, and as it eroded it fed the oceans with nutrients that fueled an explosion of early life on Earth.

Microfossils reveal warm oceans had less oxygen, Syracuse geologists say
Researchers in Syracuse University's College of Arts and Sciences are pairing chemical analyses with micropaleontology -- the study of tiny fossilized organisms -- to better understand how global marine life was affected by a rapid warming event more than 55 million years ago. Their findings are the subject of an article in the journal Paleoceanography.

Rising sea levels of 1.8 meters in worst-case scenario
The climate is getting warmer, the ice sheets are melting and sea levels are rising -- but how much? The IPCC-report in 2013 was not able to come up with an upper limit for sea level rise within this century. Now researchers from the Niels Bohr Institute and colleagues have calculated the risk for a worst-case scenario. The results indicate that at worst, the sea level would rise a maximum of 1.8 meters.
