A new record of past temperature change in the tropical Atlantic Ocean's subsurface provides clues as to why the Earth's climate is so sensitive to ocean circulation patterns, according to climate scientists at Texas A&M University. Geological oceanographer Matthew Schmidt and two of his graduate students teamed up with Ping Chang, a physical oceanographer and climate modeler, to help uncover an important climate connection between the tropics and the high latitude North Atlantic....
Lawrence LeBlond for redOrbit.com - Your Universe Online The Antarctic Peninsula has been continually shrinking for centuries, since long before the Industrial Revolution, according to an international team of researchers. However, rapid warming over the past 100 years has been unusual and, if it continues, the ice shelf could be on par for a complete collapse. Temperatures in the Antarctic Peninsula began rising around 600 years ago, occurring naturally. This was long before manmade...
PITTSBURGH, Aug. 23, 2012 /PRNewswire/ -- CONSOL Energy Inc. (NYSE: CNX), the leading diversified fuel producer in the Eastern United States, has resumed coal production at its Bailey and Enlow Fork mines in southwestern Pennsylvania. As previously reported on July 30, 2012, production was halted due to a structural failure on its newly installed above-ground conveyor system at the Bailey Preparation Plant, which processes coal from those mines. The first of two collapsed belts was...
Life in the world’s oceans faces far greater change and risk of large-scale extinctions than at any previous time in human history, a team of the world’s leading marine scientists has warned. The researchers from Australia, the US, Canada, Germany, Panama, Norway and the UK have compared events which drove massive extinctions of sea life in the past with what is observed to be taking place in the seas and oceans globally today. Three of the five largest extinctions of the past 500...
April Flowers for redOrbit.com - Your Universe Online Imagine futuristic ships shooting salt water into the clouds over the world's oceans to create clouds that reflect sunlight. Sounds like science fiction, but it could be reality before too long. An international team of researchers is taking a second look at this controversial idea to slow global warming effects and has published their concept in this month's Philosophical Transactions of the Royal Society. University of...
Brett Smith for redOrbit.com - Your Universe Online In the keynote address at the 244th National Meeting & Exposition of the American Chemical Society in Philadelphia, Nobel Laureate Mario J. Molina stressed that the latest scientific evidence has only strengthened the link between human activity and extreme weather events and global warming. Molina has some experience in working with human-atmospheric interactions on a global scale. The University of California, San Diego professor...
redOrbit Staff & Wire Reports - Your Universe Online As part of an effort to better understand and predict how animals will respond to changing environmental conditions associated with global warming, researchers at the University of California-Berkeley (UC Berkeley) have published a pair of studies investigating why some species move in response to climate change and where they go. According to Sarah Yang of the school's media relations department, the first study, published August...
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...

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...
