New Jersey -- Less sunlight reaching the Earth's surface has not translated into cooler temperatures, according to a team of solar physicists at New Jersey Institute of Technology (NJIT). The scientists, who monitor the Earth's reflectance by measuring what is known as the moon's earthshine, have observed that the amount of light reflected by Earth -- its albedo -- has increased since 2000. The result has been less sunlight reaching the Earth's surface. "Our findings have significant...
ESA -- This week's launch of MSG-2 ensures that satellite images continue to be available to European weather forecasters well into the next decade. It also marks a new chapter in a long-term space experiment measuring the available energy that drives the weather as a whole, and helping to establish how much the Earth is heating up. MSG-2's main instrument is the Spinning Enhanced Visible and Infra-red Imager (SEVIRI) which returns detailed 12-wavelength images of the Earth and its...
By Graciela Flores NEW YORK (Reuters Health) - During the fall and winter months, as days get shorter and sunlight scarce, some people "get the blues," and soon recover. But those suffering from seasonal affective disorder or "SAD" go though a much more dramatic experience, which is often difficult to overcome without help. People with SAD tend to sleep a lot, overeat, and consequently gain weight during fall or winter. They can feel extremely tired and are unable to maintain a...
By Aine Gallagher STRASBOURG, France (Reuters) - Builders and barmaids working outdoors will not have to be shielded from sunshine by their employers under European Union rules after a revolt by lawmakers on Wednesday. The European Parliament voted to leave it to individual EU states to regulate whether bosses should have to protect staff from the sun's harmful radiation, in a victory for pro-business conservative, liberal and nationalist deputies. "It's a great victory for...
NEW YORK (Reuters Health) - Anywhere from one-quarter to one-half of people catching rays at the beach may actually be addicted to tanning, according to new study findings. After interviewing 145 beachgoers, U.S. researchers found that a significant portion met a series of addiction criteria traditionally used to diagnose alcoholism and other substance use disorders. These findings suggest that regular sun-tanners may have a new type of substance disorder involving ultraviolet light,...
Sunbathing is a dangerous compulsion for some, study suggestsHealthDay News -- Some sun worshippers may actually be psychologically addicted to tanning, researchers report.The finding may explain why, despite widespread campaigns to alert people to the dangers of ultraviolet (UV) radiation, many people continue to sunbathe or use tanning booths.In two related studies, researchers also found that state laws can keep children from patronizing tanning booths, and that labeling a sunscreen...
CHICAGO (Reuters) - Using a strong sunscreen does not lead people to spend more time sunbathing in the belief they can do so safely, researchers said on Monday. Study author Alain Dupuy of the Saint Louis Hospital in Paris wanted to know if the higher protection afforded by stronger sunscreens would encourage longer sun exposure by delaying the warning sign of sunburn and giving a false sense of safety. As part of the study, sunscreen was provided for free to 367 vacationers at French...

ORLANDO, FLA. - (Aug. 10, 2005) - Summers are getting sunnier in Oregon, according to evidence presented today by University of Oregon physicists during the 2005 Solar World Congress in Orlando. The study is a first step toward testing and refining regional climate models for the Pacific Northwest that will help track global warming. In sharp contrast to reports of increased global dimming, the study's researchers reported a 10 to 15 percent increase in solar radiation at sites in Burns,...
CHICAGO "“ Airline pilots have an increased risk of nuclear cataracts [common type of cataract, associated with aging] compared with non-pilots, and that risk is associated with cumulative exposure to cosmic radiation, according to a study in the August issue of Archives of Ophthalmology, one of the JAMA/Archives journals. Commercial airline pilots are reported to be at an increased risk for some cancers, but studies on the biological effects of their exposure to cosmic radiation have been...

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 Honolulu Hawaii, during the month of March. Remember this is just data for one month during these cycles. Normal: During this cycle incoming solar activity was upwards to 48% efficient for the month, producing less than 50% of the month which is due to the large amount of daily cloud cover that is seen on the island during the early morning and...
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...
Atlantis launched from Kennedy Space Center on November 3, 1994 at 11:59 AM EST and landed at Edwards AFB on November 14 at 7:33 AM PST. The shuttle orbited 174 times at an altitude of 164 nautical miles at an inclination of 57 degrees and travelled 4.5 million miles. The mission lasted 10 days, 22 hours, 34 minutes, and 2 seconds. This mission further advanced efforts to collect data about sun's energy output, chemical makeup of the Earth's middle atmosphere, and how these factors affect...
Sunglasses are protective eyewear designed to shield the eyes from damaging or discomforting sunlight and high-energy light. They can also work as a visual aid. The ultraviolet radiation from the sun can cause several serious eye problems and many healthcare professionals recommend eye protection. However, since the 1940s sunglasses have been associated with celebrities more so than eye protection. James Ayscough experimented with tinted lenses in the mid-18th century although they were...
