Imagine a world where the rooftops and pavements of every urban area are resurfaced to increase the reflection of the Sun's light rays. Well, this is exactly what a group of Canadian researchers have done in an attempt to measure the potential effects against global warming. In a study published today, 13 April, in IOP Publishing's journal Environmental Research Letters, researchers from Concordia University created this scenario to see what effect a global increase in surface reflectance...

On the hottest day of the New York City summer in 2011, a white roof covering was measured at 42 degrees Fahrenheit cooler than the traditional black roof it was being compared to, according to a study including NASA scientists that details the first scientific results from the city's unprecedented effort to brighten rooftops and reduce its "urban heat island" effect. The dark, sunlight-absorbing surfaces of some New York City roofs reached 170 degrees Fahrenheit on July 22, 2011, a day...

Image 1 - Human Activity, Not Solar Activity, Drives Global Warming
2012-02-01 05:11:53

A new NASA study underscores the fact that greenhouse gases generated by human activity -- not changes in solar activity -- are the primary force driving global warming. The study offers an updated calculation of the Earth's energy imbalance, the difference between the amount of solar energy absorbed by Earth's surface and the amount returned to space as heat. The researchers' calculations show that, despite unusually low solar activity between 2005 and 2010, the planet continued to absorb...

Scientists have developed important new insight into the sensitivity of global temperature to changes in the Earth´s radiation balance over the last half million years. The sensitivity of global temperature to changes in the Earth´s radiation balance (climate sensitivity) is a key parameter for understanding past natural climate changes as well as potential future climate change. In a study in Journal of Climate, researchers from the Universities of Southampton and Bristol for...

Greenhouse Gases Reach Record Highs, WMO Reports
2011-11-22 06:15:52

Carbon dioxide, methane, and nitrous oxide levels reached record highs in 2010, surpassing what experts had previously called the worst-case scenario for these greenhouse gases, the World Meteorological Organization (WMO) announced on Monday. The WMO, which is the U.N.'s weather agency, reported that CO2 levels increased by 2.3 parts per million, to 389 ppm, from 2009 to last year, according to Reuters reporter Tom Miles. That single-year increase exceeds the average for both the 1990s...

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...

NEW YORK, Oct. 14, 2011 /PRNewswire/ -- Locus Energy is preparing to launch Virtual Irradiance(TM) -- a patent pending software service providing highly accurate estimates of historical and real-time solar irradiance across North America. The service will be offered as an add-on for all users of the company's web-based residential and commercial monitoring platform. Using patent pending algorithms, Locus Energy has developed an affordable high-quality model capable of estimating solar...

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...

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...
