Examining gas outlets off the coast of Spitsbergen with the submersible JAGO West of Spitsbergen methane gas is effervescing out of the seabed. Is this an indication that methane hydrates in the seabed are dissolving due to rising temperatures? And what would the effects be? An expedition with the German research vessel MARIA S. MERIAN and the submersible JAGO lead by GEOMAR | Helmholtz Centre for Ocean Research Kiel hopes to help answer these questions. The expedition begins today in...
redOrbit Staff & Wire Reports - Your Universe Online Arctic sea ice is melting away far more rapidly than experts had previously predicted, with more than 215 cubic miles (900 cubic kilometers) worth disappearing from the Arctic Ocean over the past year, according to information obtained by the European Space Agency's CryoSat-2 probe. According to Robin McKie, Science Editor with the UK newspaper The Guardian, that constitutes a 50% higher rate of loss than the majority of...
WASHINGTON, Aug. 10, 2012 /PRNewswire-USNewswire/ -- The Global Adaptation Institute (GAIN) will host an international Open Consultation process before release of the 2012 GAIN Index in October. This consultation reflects GAIN's commitment to updating the index each year to incorporate new or revised data and advice on methodological, design and communications improvements. The GAIN Index (index.gain.org) is a navigation tool to help guide investments in adaptation and assess a...
PITTSBURGH, Aug. 9, 2012 /PRNewswire/ -- CONSOL Energy Inc. (NYSE: CNX), the leading diversified fuel producer in the Eastern United States, previously reported on July 30, 2012 that it incurred a structural failure on its newly installed above-ground conveyor system at the Bailey Preparation Plant in Southwestern Pennsylvania. This incident affected production at the company's Bailey and Enlow Fork mines. Reconstruction of the affected systems is underway. At this time, we estimate...
Methane emissions jump dramatically Washington State University researchers have documented an underappreciated suite of players in global warming: dams, the water reservoirs behind them, and surges of greenhouse gases as water levels go up and down. Bridget Deemer, a doctoral student at Washington State University-Vancouver, measured dissolved gases in the water column of Lacamas Lake in Clark County and found methane emissions jumped 20-fold when the water level was drawn down. A...
April Flowers for redOrbit.com - Your Universe Online A new study from the Yale School of Forestry & Environmental Studies asserts that diseased trees may be a significant new source of methane gas that causes climate change. The study, "Elevated Methane Concentrations in Trees of an Upland Forest," which will be published in Geophysical Research Letters sampled sixty trees at the Yale Myers Forest in northeastern Connecticut. The Yale Myers Forest is 7,480 acres of mixed...
April Flowers for redOrbit.com - Your Universe Online Earth's land areas have become more likely to experience an extreme summer heat wave according to a new statistical analysis by NASA scientists. The study, published August 6, 2012, in Proceedings of the National Academy of Sciences, show that the recent bouts of extremely warm summers, including the intense heat wave afflicting the U.S. Midwest this year, are likely the consequence of global warming. According to James Hansen...
redOrbit Staff & Wire Reports - Your Universe Online More than half of the contiguous states in the US were experiencing drought by early July 2012, and over 170 all-time American heat records were tied or surpassed during the month of June, according to new research released by NASA scientists on Friday. Many of the record highs experienced during the sixth month of the year surpassed records originally set during the months of July and August, which historically have been hotter...
Brett Smith for redOrbit.com - Your Universe Online As the world’s greatest athletes compete for gold, silver, and bronze in London, new scientific evidence suggests that future summer Olympics could be hosted in a more remote location: Antarctica. An international team of climate scientists has discovered 50 million-year-old fossilized pollen in the seabed off the eastern coast of the polar continent, according to their report published this week in the journal Nature. The...
Palm trees once thrived on today's icy coasts 52 million years ago Given the predicted rise in global temperatures in the coming decades, climate scientists are particularly interested in warm periods that occurred in the geological past. Knowledge of past episodes of global warmth can be used to better understand the relationship between climate change, variations in atmospheric carbon dioxide and the reaction of Earth's biosphere. An international team led by scientists from the Goethe...

An urban heat island (UHI) is a metropolitan area that is drastically warmer than its surrounding rural areas because of human activities. The phenomenon was first looked into and described by Luke Howard during the 1810s, although he wasn’t the one to name the phenomenon. The difference in temperature is normally bigger at night as opposed to during the day, and it most obvious when winds are weak. Seasonally, UHI is seen during the summer and the winter. The key cause of the urban heat...
Climate change is a substantial and lasting change in the statistical distribution of weather patterns over periods of time ranging from decades to millions of years. It might be a change in the average weather conditions, or in the distribution of weather around the average conditions. Climate change is a result of factors that include oceanic processes, biotic processes, variations in solar radiation received buy Earth, volcanic eruptions, and plate tectonics, and human induced alterations...
Being a meteorologist for over thirteen years you start to take note of many things in the atmosphere and how they repeat themselves. Our Climate is no different. The definition of climate is stated as: the collective weather data in regards to moisture and temperature for over 30 years for the same location. So to better understand our climate we need to look at this. First, we have average temperatures for given places based on the 30 year average. Some years the temps are warmer or...
The water cycle (or hydrologic cycle) describes the continuous movement of water above, below, and on the planet. Since the water cycle is in fact a "cycle", there is no beginning or end. Water exists in three states: liquid, vapor, and ice. Although the balance of water on our planet is fairly constant, individual water molecules may come and go. The water cycle is driven by the sun. The sun heats the oceans and allows water to evaporate into the air. The sun also heats snow and ice which...
Arctic haze is a phenomenon that occurs in the atmosphere at high latitudes in the Arctic due to air pollution. What distinguishes Arctic haze from haze found elsewhere, is the ability of its chemical ingredients to endure in the atmosphere for a longer period of time compared to other pollutants. Due to limited snowfall, rain, or turbulent air to displace pollutants from the polar air in the spring, Arctic haze can continue for more than a month in the northern atmosphere. Arctic haze...
