Study Finds Human Activity Affects Vertical Structure Of Atmospheric Temperature
2013-09-17 13:05:39

Lawrence Livermore National Laboratory Human influences have directly impacted the latitude/altitude pattern of atmospheric temperature. That is the conclusion of a new report by scientists from Lawrence Livermore National Laboratory and six other scientific institutions. The research compares multiple satellite records of atmospheric temperature change with results from a large, multi-model archive of simulations. "Human activity has very different effects on the temperature of the...

Satellites Providing Information On Earth’s Albedo With Remarkable Accuracy
2013-09-06 11:48:30

[ Watch The Video - Reflecting Power Of Earth’s Albedo ] ESA The amount of sunlight being absorbed or reflected by Earth is one of the driving forces for weather and climate. Satellites are providing this information with unprecedented accuracy. The reflecting power of a surface is known as ‘albedo’. Bright snow and ice have a high albedo, meaning they reflect solar radiation back into space, while green areas like forests and fields have a much lower albedo. The lower the...

Runaway Greenhouse Planet
2013-07-30 11:42:08

Brett Smith for redOrbit.com - Your Universe Online When a planet absorbs too much solar radiation, its atmosphere reaches a tipping point - overheating, boiling its oceans and filling with steam. The result is an uninhabitable world much like Venus. This 'runaway greenhouse' phenomenon typically occurs just inside the habitable zone orbited by planets like Earth, and a new report in Nature Geoscience indicates that reaching the tipping point may be easier than previously thought....

Wildfire Climate Interactions Pose Long Term Problems
2013-05-22 10:46:39

redOrbit Staff & Wire Reports - Your Universe Online The US Forest Service voiced its concern on Tuesday over the atmospheric effects of wildfire emissions on climate change, saying the issue is of great importance to scientists and policymakers alike. The warnings are particularly important given recent projections of an average 50-percent increase in wildfires across the US — and over 100 percent in some areas of the West — by 2050, the Service said. The agency...

Manhattan Heat-Related Deaths Expected To Increase
2013-05-20 05:20:42

redOrbit Staff & Wire Reports - Your Universe Online Increasing temperatures could cause heat-related deaths in Manhattan to increase by one-fifth by the end of the decade, and nearly double before the end of the century, according to new research published in this week´s edition of the journal Nature Climate Change. In the study, scientists from the Columbia University's Earth Institute and the Mailman School of Public Health report that deaths related to global warming could...

The Bureau of Reclamation and collaborators developed new downscaled climate projections that allow water managers to incorporate the new Coupled Model Inter-comparison Project Phase 5 data from the World Climate Research Program into their water management planning. The data, representing 234 contemporary climate projections for the contiguous United States, was downscaled to a 12 kilometer resolution in order to be more useful to water managers. Washington, D.C. (PRWEB) May 09, 2013 The...

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...

Peter Suciu for redOrbit.com — Your Universe Online It has long been known that light colors can reflect heat, while dark colors can absorb heat, but it is all a matter of light. This is because light is energy and darker colors have greater absorption, thus more heat. Even light-colored materials, such as cement or concrete, can absorb heat during the day and release it at night. Because buildings are used primarily during the day, it is typically required to cool them during...

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...

Incoming Solar Radiation Impacts By Various Weather Cycles
2012-07-23 11:19:47

The above image looks at the month of March for the three cycles known as Normal Phase, El-Nino, and La-Nina. The data was recorded for the city of Austin Texas. Remember this is just data for one month during these cycles. Normal: During this cycle incoming solar activity was upwards to 60% efficient for the month, producing enough solar energy that only 40% of the month would have not had strong incoming radiation. EL-Nino: This phase provided the area with an extended number of...

call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
