Lawrence LeBlond for redOrbit.com - Your Universe Online Scientists from three universities have found that record temperatures in 2010 and 2012 resulted in the earliest spring flowering season in the eastern United States in more than 160 years. Using the phenological records of two iconic American naturalists, Henry David Thoreau and Aldo Leopold, scientists have shown that some springtime bloomers have appeared as much as a month earlier in response to the warming climate. This study...
[ Watch the Video: NASA's Analysis of 2012 Global Temperature ] April Flowers for redOrbit.com - Your Universe Online Scientists at NASA report that 2012 was the ninth warmest year on record since 1880. This continues a long-term global trend of rising temperatures. With one exception, 1998, the nine warmest years in the 132-year record have all occurred since 2000. The hottest years on record were 2010 and 2005. An updated analysis released this past Tuesday by NASA's Goddard...
United States Geological Survey While the iconic Haleakalā silversword plant made a strong recovery from early 20th-century threats, it has now entered a period of substantial climate-related decline. New research published this week warns that global warming may have severe consequences for the silversword in its native habitat. Known for its striking rosette, the silversword grows for 20-90 years before the single reproductive event at the end of its life, at which time it produces a...
International Geosphere-Biosphere Programme Reducing diesel engine emissions would reduce warming Black carbon is the second largest man-made contributor to global warming and its influence on climate has been greatly underestimated, according to the first quantitative and comprehensive analysis of this issue. The landmark study published in the Journal of Geophysical Research-Atmospheres today says the direct influence of black carbon, or soot, on warming the climate could be about...
WASHINGTON, Jan. 15, 2013 /PRNewswire-USNewswire/ -- NASA scientists say 2012 was the ninth warmest of any year since 1880, continuing a long-term trend of rising global temperatures. With the exception of 1988, the nine warmest years in the 132-year record all have occurred since 2000, with 2010 and 2005 ranking as the hottest years on record.

[ Watch the Video: What Is Global Warming ] April Flowers for redOrbit.com - Your Universe Online Measurements around the world indicate that monthly temperature extremes have become more frequent. A new study from the Potsdam Institute for Climate Impact Research (PIK) and the Compluntense University reveals that on average, there are five times more record-breaking hot months globally than would be expected without long-term global warming. The study, published in Climate...
redOrbit Staff & Wire Reports – Your Universe Online A 1,000-plus page draft report compiled by US government scientists warns global warming is already having a notable impact on the day-to-day lives of Americans, disrupting their health and their homes, among other things, various media outlets reported on Saturday. According to AP Science Writer Seth Borenstein, the 1,146-page National Climate Assessment, which was commissioned by the federal government, “details in dozens...
NASA Science In the galactic scheme of things, the Sun is a remarkably constant star. While some stars exhibit dramatic pulsations, wildly yo-yoing in size and brightness, and sometimes even exploding, the luminosity of our own sun varies a measly 0.1% over the course of the 11-year solar cycle. There is, however, a dawning realization among researchers that even these apparently tiny variations can have a significant effect on terrestrial climate. A new report issued by the National...
redOrbit Staff & Wire Reports - Your Universe Online A mild winter followed by a long, sweltering summer with widespread drought made 2012 the warmest year on record for the continental United States, the National Oceanic and Atmospheric Administration (NOAA) announced on Tuesday. The average annual U.S. temperature rose to 55.32 degrees Fahrenheit last year, one degree warmer than the previous record set in 1998 and 3.2 degrees warmer than the 20th century average, the federal...
As they typically result from severe external perturbations, it is of vital interest how stable the most desirable state is. Surprisingly, this basic question has so far received little attention. Now scientists of the Potsdam Institute for Climate Impact Research (PIK), in a paper published in Nature Physics, propose a new concept for quantifying stability. "Up to now, science was able to say if a complex system is stable or not, but it wasn't able to properly say how stable it is," says...

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...
