scale insect infestation on a red maple
2014-07-25 02:00:50

Matt Shipman, North Carolina State University New research from North Carolina State University shows that urban "heat islands" are slowly killing red maples in the southeastern United States. One factor is that researchers have found warmer temperatures increase the number of young produced by the gloomy scale insect – a significant tree pest – by 300 percent, which in turn leads to 200 times more adult gloomy scales on urban trees. "We'd been seeing higher numbers of plant-eating...

Join Arizona-based American Cooling and Heating in this study of the economic consequences associated with combating human-triggered climate change. Mesa, AZ (PRWEB) May 10, 2014 Managing Global Warming, Climate Change and the Economic Fallout After enduring over a decade of year-by-year temperature increases averaging nearly two degrees Fahrenheit, Arizona residents don’t tend to argue the validity of global warming or the reality of undesirable climate change. The heat is here. This...

Reducing Warming Caused By Urban Expansion

Cheryl Dybas, National Science Foundation Punxsutawney Phil's Groundhog Day prediction may have called for six more weeks of winter, but the first day of spring is now around the corner. After a long season of snow and ice across the US and around the world, warmer weather will likely be greeted with open arms. In a hotter world, however, the bloom may quickly be off the rose. Cities: The new deserts? When we think about the most sizzling locations on the planet, we often...

Research Reveals Give And Take Of Urban Temperature Mitigating Technologies
2014-02-10 12:14:36

Arizona State University Life in a warming world is going to require human ingenuity to adapt to the new realities of Earth. Greenhouse-gas induced warming and megapolitan expansion are both significant drivers of our warming planet. Researchers are now assessing adaptation technologies that could help us acclimate to these changing realities. But how well these adaptation technologies – such as cool roofs, green roofs and hybrids of the two – perform year round and how this...

WASHINGTON, Jan. 21, 2014 /PRNewswire-USNewswire/ -- NASA scientists say 2013 tied with 2009 and 2006 for the seventh warmest year since 1880, continuing a long-term trend of rising global temperatures. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) With the exception of 1998, the 10 warmest years in the 134-year record all have occurred since 2000, with 2010 and 2005 ranking as the warmest years on record. NASA's Goddard Institute for Space Studies (GISS) in New...

More carbon dioxide is released from residential lawns than corn fields according to a new study. And much of the difference can likely be attributed to soil temperature. The data, from researchers at Elizabethtown College, suggest that urban heat islands may be working at smaller scales than previously thought. These findings provide a better understanding of the changes that occur when agricultural lands undergo development and urbanization to support growing urban populations. David...

Urban warming effect increases scale insects on willow oaks in hotter parts of city Higher temperatures in cities can be a key driver of insect pest outbreaks on trees in urban areas, according to research published March 27 in the open access journal PLOS ONE by Emily Meineke from North Carolina State University and colleagues from other institutions. The researchers found that a scale insect that exclusively feeds on oak trees was 13 times more abundant on willow oaks in the hottest...

redOrbit Staff & Wire Reports - Your Universe Online Large metropolitan areas could be drastically impacting the weather where you live, even if they´re hundreds of miles away, researchers from the Scripps Institution of Oceanography (SIO); the University of California, San Diego (UCSD); Florida State University (FSU); and the National Center for Atmospheric Research (NCAR) claim in a new study. The researchers, who report their findings in the journal Nature Climate Change,...

Pavements Created To Fight Climate Change May Increase Energy Consumption For Surrounding Buildings
2012-11-08 17:19:35

UCSD Jacobs School of Engineering A push to replace old, heat-trapping paving materials with new, cooler materials could actually lead to higher electricity bills for surrounding buildings, engineers at the University of California, San Diego, have found. Researchers published their findings Oct. 29 in the new Journal of Urban Climate. The new paving materials are designed to lower the overall temperature of the areas where they are used–something that the study, which was focused...

Urban Heat Island
2013-04-02 15:35:21

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...
