Impacts Of Deforestation Varies By Latitude
2011-11-17 05:49:49

Scientists from 20 institutions around the world said that the impact of deforestation on global warming varies with latitude. Researchers say these new findings, which were published in the journal Nature, call for new climate-monitoring strategies. "It depends where the deforestation is," UC Davis atmospheric science Professor Kyaw Tha Paw U, a study co-author, said in a press release "It could have some cooling effects at the regional scale, at higher latitudes, but there's no...

Image 1 - Satellites Predict City Hot Spots

Satellites are helping to forecast the location of urban areas most affected during heat waves, helping planners to design cooler, more comfortable cities. The temperature in densely urbanized areas can be several degrees higher than in nearby rural areas — a phenomenon known as the ℠urban heat island´ effect. These ℠heat islands´ are particularly noticeable at night. During the day, cities accumulate solar radiation and release the energy after the Sun sets....

MELBOURNE, Australia, July 15, 2011 /PRNewswire/ -- AppliCad's first foray into the solar market has proved to be a huge success with the launch of their new Solar Wizard software at the recent InterSolar US show in San Francisco. SolarWizard is a 3D modelling program that calculates solar radiation and shadows on a 3D model of the client's structure and helps determine the optimum location of solar assets such as PV arrays and solar thermal equipment. It should not have been a surprise...

The mass extinction of marine life in our oceans during prehistoric times is a warning that the Earth will see such an extinction again because of high levels of greenhouse gases, according to new research by geologists. Professor Martin Kennedy from the University of Adelaide (School of Earth & Environmental Sciences) and Professor Thomas Wagner from Newcastle University (Civil Engineering and Geosciences) have been studying 'greenhouse oceans' "“ oceans that have been depleted of...

Accounting for wavelength effects will likely improve climate modelsAtmospheric scientists trying to pin down how clouds curb the amount of sunlight available to warm the earth have found that it depends on the wavelength of sunlight being measured. This unexpected result will help researchers improve how they portray clouds in climate models.Additionally, the researchers found that sunlight scattered by clouds "” the reason why beachgoers can get sunburned on overcast days "” is...

'Outer' tree canopy leaves influence the sunlight reaching inner canopy leaves by changing their shape, says a new study. The shape and physiology of leaves within the tree canopy is not constant, and can vary depending on their position within the tree crown. This phenomenon is expected to have important consequences for how trees cope with stress and use resources. A new study describes how the leaves in the outer canopy of olive trees can influence the light environment within the canopy...

The deadly heat wave that crippled Russia last summer was due to a natural atmospheric phenomenon often associated with weather extremes and not directly caused by global warming, according to a new study by the National Oceanic and Atmospheric Association (NOAA). And while the scientists could not attribute the intensity of the Russian heat wave to climate change, they did find that extreme heat waves are likely to become more frequent in the region in the coming decades. The researchers...

A new analysis of the Northern Hemisphere's "albedo feedback" over a 30-year period concludes that the region's loss of reflectivity due to snow and sea ice decline is more than double what state-of-the-art climate models estimate. The findings are important, researchers say, because they suggest that Arctic warming amplified by the loss of reflectivity could be even more significant than previously thought. The study was published online this week in Nature Geoscience. It was funded...

PHOENIX, Jan. 17, 2011 /PRNewswire/ -- Emerald Cities(TM) USA Ltd. (div. of Emerald Cities(TM) International Ltd.) has just resurfaced the world's first solar reflective "Green" asphalt parking lot to demonstrate the importance of "Cool Pavement" addressing Urban Heat Island in the cities (see photos at www.emeraldcoolpavements.com/pressrelease/Installation.pdf). This 24,000 sq.ft. parking lot was donated to Mayor Gordon's Phoenix Recovery Zone at the Duffy Charter School where asphalt...

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...
