Climate instruments mounted aboard the Horizon Spirit container ship begin taking data A Horizon Lines container ship outfitted with meteorological and atmospheric instruments installed by U.S. Department of Energy (DOE) scientists from Argonne National Laboratory and Brookhaven National Laboratory will begin taking data today for a yearlong mission aimed at improving the representation of clouds in climate models. The study, a collaborative effort between DOE’s Atmospheric Radiation...
A new study has found that climate-prediction models are good at predicting long-term climate patterns on a global scale but lose their edge when applied to time frames shorter than three decades and on sub-continental scales. Climate-prediction models show skills in forecasting climate trends over time spans of greater than 30 years and at the geographical scale of continents, but they deteriorate when applied to shorter time frames and smaller geographical regions, a new study has found....
April Flowers for redOrbit.com - Your Universe Online Extreme precipitation events in the tropics can come in many forms; thunderstorm complexes, flood-inducing monsoons and wide-sweeping cyclones like the recent Hurricane Isaac. Scientists expect global warming to intensify extreme precipitation, but the rate of intensification in the tropics remains unclear. A new study from MIT, published online this week in Nature Geoscience, gives an estimate based on model simulations and...
TUCSON, Ariz., Sept. 4, 2012 /PRNewswire-USNewswire/ -- Thousands of accused witches were burned at the stake in medieval times in an effort to protect their communities from bad weather, stated Jane Orient, M.D., president of Physicians for Civil Defense. It didn't work then, of course, as Europe continued to suffer greatly during the Little Ice Age. And human beings still do not have the power to control the climate, she said. Orient spoke at the 30(th) annual meeting...
April Flowers for redOrbit.com - Your Universe Online Global warming is a scientific reality, whether we want to ascribe it to natural processes or man-made effects. One of the questions raised by this phenomenon is how will it affect biodiversity on the planet. A new study by the Universities of York, Glasgow and Leeds, reveals answers that conflict with past studies. The new research involved analysis of fossil and geological records going back 540 million years and it suggests that...
A cost analysis of the technologies needed to transport materials into the stratosphere to reduce the amount of sunlight hitting Earth and therefore reduce the effects of global climate change has shown that they are both feasible and affordable. Published today, 31 August 2012, in IOP Publishing's journal Environmental Research Letters, the study has shown that the basic technology currently exists and could be assembled and implemented in a number of different forms for less than USD $5...
Brett Smith for redOrbit.com – Your Universe Online Using a “non-stationary” model that factors in the recent warming trends of the past few years, researchers from the Scripps Institution of Oceanography at UC San Diego have determined that California heat waves will become more humid and stronger in populous coastal areas. Traditionally, California heat waves primarily affect the interior desert and valley areas that become hot during the day and both cooler and drier at night....
April Flowers for redOrbit.com - Your Universe Online Arctic sea ice has melted to a record low extent; the smallest ever recorded since satellites began measuring it in 1979. On August 26, 2012, the Arctic sea ice extent fell to 1.58 million square miles, or 4.10 million square kilometers. This is 27,000 square miles below the previous record daily low of September 18, 2007, says new data from the University of Colorado's National Snow and Ice Data Center (NSIDC). Sea ice extent...
April Flowers for redOrbit.com - Your Universe Online Scientists have long suspected that the Sun's 11-year cycle influences climate of certain regions on Earth. Records of average, seasonal temperatures do not date back far enough to confirm any patterns, though. An international team of researchers, armed with a unique proxy, show that unusually cold winters in Central Europe are related to low solar activity – when sunspot numbers are minimal. Germany's Rhine River freezing is the...
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....

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...
