Where are America's Greenest Buildings?

Ok, no surprise to see Washington, D.C. or San Francisco ranked high in a list of the cities with America's greenest buildings. But Atlanta? Georgia's capital was the only southern state to make the top ten in the 2014 U.S. Clean Tech Leadership Index, released July 15 by Clean Edge. The cleantech research firm tracks the cleantech progress of the 50 largest metro areas and the 50 states.

California getting tough with water wasters!

Regulatory news - ENN - July 16, 2014 - 9:31am
Californians who waste water will have to pay up to $500 a day for their extravagance under new restrictions approved Tuesday by the State Water Resources Control Board. The move comes after the board concluded that voluntary conservation measures have failed to achieve the 20 percent reduction in water use that Gov. Jerry Brown was hoping for, reports The Associated Press. In fact, a survey by the board showed a 1 percent increase in water use in May compared to the same month a year ago.

Rainwater discovered below the Earth's fractured upper crust

Climate Change News - ENN - July 16, 2014 - 7:40am
When it rains, where does the water go? Well for one, a lot of rainwater will funnel its way off roads and impermeable surfaces and will make its way into storm sewers. Another path might be directly into rivers and lakes. Or, rainwater might get soaked up by soil where it will then infiltrate into the ground and replenish aquifers. But just how deep does this rainwater infiltrate? According to new research, rainwater can penetrate below the Earth's fractured upper crust - which is at least eight miles below the Earth's surface!

Sand Power: A Better Battery

Technology of the future is hard to see coming – sometimes because you can't see it. Advances in nanotechnology are the driving force behind longer lasting Lithium-ion batteries. Currently, Lithium-ion batteries are used to power every-day technologies like cell phones, computers, cameras and cars. Their energy source is a carbon-based graphite anode, which is nothing short of polarizing. Battery life has always been a major concern with Li-ion batteries. The solution is the most abundant compound in the earth's crust: SiO2, - or – more commonly – sand. The next generation of battery technology is using sand as a source for the production of nano-silicon, an anode material for Li-ion batteries.

Drought Conditions Linked to Human Activity

Climate Change News - ENN - July 15, 2014 - 9:52am
US Government scientists have developed a new high-resolution climate model that shows southwestern Australia's long-term decline in fall and winter rainfall is caused by increases in manmade greenhouse gas emissions and ozone depletion. "This new high-resolution climate model is able to simulate regional-scale precipitation with considerably improved accuracy compared to previous generation models," said Tom Delworth, a research scientist at NOAA's Geophysical Fluid Dynamics Laboratory in Princeton, N.J., who helped develop the new model and is co-author of the research.

Exposure to Aircraft noise a continuing problem even with quieter engines

Millions of urban Europeans are exposed to aviation noise that contributes to stress, high blood pressure and even weight gain, say health specialists who want stronger measures to make flying quieter. While new-generation jet engines are on average 75% quieter than than their 20th century predecessors, the advance in technology has been offset by a steady rise in flights and a demand for bigger passenger planes.

Is London measuring its urban heat island accurately?

Climate Change News - ENN - July 14, 2014 - 10:15am
London's urban heat island effect, which keeps night-time temperatures in the capital warmer than in surrounding rural areas, may have been underestimated by up to 45 per cent. The heat can pose serious health risks, particularly for the elderly and very young.

This is a extra special year for "Super Moons"

Super Moons are full moons that are extra, well, super! They are super because they appear larger in the evening sky than your run of the mill full moon. In June of last year, a full Moon made headlines. The news media called it a "supermoon" because it was 14% bigger and 30% brighter than other full Moons of 2013. Around the world, people went outside to marvel at its luminosity. If you thought one supermoon was bright, how about three? The full Moons of summer 2014—July 12th, August 10th, and Sept. 9th--will all be supermoons. The scientific term for the phenomenon is "perigee moon." Full Moons vary in size because of the oval shape of the Moon's orbit. The Moon follows an elliptical path around Earth with one side ("perigee") about 50,000 km closer than the other ("apogee"). Full Moons that occur on the perigee side of the Moon's orbit seem extra big and bright.

New Study Links Kidney Stones to...Warming Climate?

Climate Change News - ENN - July 11, 2014 - 3:14pm
In a study that may both reflect and foretell a warming planet's impact on human health, a research team found a link between hot days and kidney stones in 60,000 patients in several US cities with varying climates. "We found that as daily temperatures rise, there is a rapid increase in the probability of patients presenting over the next 20 days with kidney stones," said study leader Gregory E. Tasian, MD, MSc, MSCE, a pediatric urologist and epidemiologist at The Children's Hospital of Philadelphia (CHOP), who is on the staff of the Hospital's Kidney Stone Center as well as the Hospital's Center for Pediatric Clinical Effectiveness (CPCE).

Arctic sea ice trends confirmed by Whalers' logs

Climate Change News - ENN - July 11, 2014 - 11:14am
Log books from British whaling ships more than 200 years ago have given new insights into the history of the Arctic sea ice, reports Tim Radford. A new study reveals that the scale of ice melt in the Arctic over the last few decades is new and unprecedented. The retreat of the ice in the last 30 years is part of a more recent and new pattern of climate change. British whaling ships from Tyneside in the north-east of England made 458 trips to the edge of the Arctic ice between 1750 and 1850.

Record Radiation in South America

Regulatory news - ENN - July 11, 2014 - 10:00am
Astrobiologists from the United States and Germany recorded the highest known level of solar UV radiation to reach Earth's surface. This was around 10 years ago. On December 29, 2003, the UV Index (UVI) peaked, reaching the blistering number of 43.3 over the Andes Mountains in Bolivia. To put this in context, a beachgoer in the United States would expect a UVI of 8 or 9 on a summer day. Even with an 8 or a 9, one may not escape the day without sunburn. Nonetheless, it has taken scientists 10 years to detail a report of this data while taking into account all of the variables and anomalies monitored from an international network of dosimeters – or Eldonets (European Light Dosimeter Network) – that measure UV radiation worldwide. This system is comprised of more than 100 stations across 5 continents to account for variation in the atmosphere above each station.

2014 Natural Disaster Damage and Death Toll Well Below Average

Climate Change News - ENN - July 10, 2014 - 5:13pm
Extreme weather events and other natural disasters claimed the lives of more than 2,700 people and caused around US $42 billion in damage worldwide in the first half of 2014, but this was well below the first half of last year and a 10-year average, according to new research from reinsurer Munich Re. However, the briefing report warns that towards the end of the year the natural climate phenomenon El Niño may impact regions differently in terms of the number and intensity of weather extremes.

New Study Quantifies Causes of the "Urban Heat Island" Effect

A new Yale-led study quantifies for the first time the primary causes of the "urban heat island" (UHI) effect, a common phenomenon that makes the world's urban areas significantly warmer than surrounding countryside and may increase health risks for city residents. In an analysis of 65 cities across North America, researchers found that variation in how efficiently urban areas release heat back into the lower atmosphere — through the process of convection — is the dominant factor in the daytime UHI effect. This finding challenges a long-held belief that the phenomenon is driven principally by diminished evaporative cooling through the loss of vegetation.

Our newest Astronauts are fruit flies!

Becoming an Astronaut is a big deal! Men and women selected to go into space are very carefully chosen. They go through rigorous medical evaluations to make sure they are healthy and that their bodies can withstand the forces of liftoff and re-entry. And they go through months and months of training to prepare them for their first space flight. Now NASA is sending untested, untrained astronauts into space. Of course, they are not human, they are fruit flies! Fruit flies are bug eyed and spindly, they love rotten bananas, and, following orders from their pin-sized brains, they can lay hundreds of eggs every day. We have a lot in common. Genetically speaking, people and fruit flies are surprisingly alike, explains biologist Sharmila Bhattacharya of NASA's Ames Research Center. "About 77% of known human disease genes have a recognizable match in the genetic code of fruit flies, and 50% of fly protein sequences have mammalian analogues."

Cell Phone Conservation

Regulatory news - ENN - July 9, 2014 - 11:35am
Some of the world's most endangered forests may soon benefit from better protection, thanks to discarded treasures from the consumer society - mobile phones. A Californian technology startup, Rainforest Connection (RFCx), has developed a tool - made from recycled smartphones - that it says will pilot new ways to monitor and stop illegal logging and animal poaching throughout Africa's equatorial forests. RFCx has formed a partnership with the Zoological Society of London (ZSL), an international scientific charity that works for the worldwide conservation of animals and their habitats. The two organisations are planning to install the anti-deforestation, anti-poaching technology in Cameroon this year.
