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

Climate Change News - ENN - July 10, 2014 - 8:14am
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.

Vast reservoir of gas may fuel star creation in our galaxy

The Milky Way may have found a solution to its gas shortage. Astronomers had calculated that our home galaxy possesses only enough fuel to forge new stars for just a few billion more years. But scientists have now discovered that a long stream of gas falling into the Milky Way is four times as massive as previously thought and could power our galaxy's starmaking career for a long time to come. "It's a very beautiful study with surprising results," says Leo Blitz of the University of California, Berkeley, an astronomer who was not part of the project.

Climate Change Decadal Pause Study – Accidental Climate Mitigation

Regulatory news - ENN - July 8, 2014 - 12:13pm
Professors Jesse Thé and Roydon Fraser from the University of Waterloo are initiating a study on the potential cause of the decade long pause on global warming. This is an interview with Prof. Thé, as a disclosure is also ENN’s Editor-in-Chief. . ENN: What is causing this decade long pause on the average global temperature increase? Prof. Thé: First of all, note that the last decade was the warmest on record. While the maximum temperatures are not increasing as fast, we are not seen a real pause on temperature increase, just a significant reduction on its growth rate. Second, researchers are not certain and our work at this stage can only be placed in the scientific method as a hypothesis. Until we develop the full analysis, all my views in this interview are based on our hypothesis that the pause in the temperature increase is cause by the aerosol formation form the massive burning of coal in China (50% of global consumption of coal) and India.

SAR11 and Methane

Climate Change News - ENN - July 8, 2014 - 9:07am
With the focus on reducing carbon emissions, we often forget about methane – another greenhouse gas that is way more powerful as an atmospheric pollutant than carbon dioxide. Methane emissions can come from industry, agriculture, and waste management activities, but can also be emitted from a number of natural sources. One newly discovered natural source: SAR11.

A long-term study of the links between climate and marine life along the rapidly warming West Antarctic Peninsula reveals how changes in physical factors such as wind speed and sea-ice cover send ripples up the food chain, with impacts on everything from single-celled algae to penguins.

Conserving water and climate change

Climate Change News - ENN - July 6, 2014 - 7:47am
There's more to trying to slow down climate change than just cutting greenhouse gas emissions. Technology, policies or plans that aim to do so should also take environmental factors such as water usage into account. A more integrated approach might make some options considerably more attractive than others, especially when implemented in arid countries such as Australia, advise Philip Wallis of Monash University in Australia and colleagues, in an article in Springer's journal Climatic Change. The researchers considered the example of Australia to show how water usage influences the appeal of certain preferred mitigation options. They analyzed 74 options that were ranked in the influential "Low Carbon Growth Plan for Australia" in 2010, and together could help Australia cut its 2000 emission levels by 25 percent by 2020.

Sea Grass in coastal New England waters under attack by Nitrogen

Climate Change News - ENN - July 5, 2014 - 9:29am
A federally funded scientific study on regional seagrass health recently released by The Nature Conservancy points to nitrogen pollution — from sewage and fertilizers — and warmer water temperatures as the killer threats to seagrasses throughout the coastal waters of southern New England. Seagrass is vital habitat for fish and shellfish and is important for water quality.

Frackable rock under groundwater aquifers raise water contamination fears

A study by the British Geological Survey and the Environment Agency reveals that almost all the the oil and gas bearing shales in England and Wales underlie drinking water aquifers, raising fears that widespread water contamination could occur. The British Geological Survey (BGS) in partnership with The Environment Agency (EA) have published a map which show the depth to each shale gas and oil source rock below principal groundwater aquifers in England and Wales.

What are comets?

Scientists have speculated for centuries about comets. Why do the become visible on an irregular interval? Why does the tail always point away from our sun? What are comets made of? Are they balls of ice, or more like an asteroid? Now NASA may finally get some concrete answers with a current mission that will land on a comet later this year! Comet 67P/Churyumov-Gerasimenko is releasing the Earthly equivalent of two glasses of water into space every second. The observations were made by the Microwave Instrument for Rosetta Orbiter (MIRO), aboard the European Space Agency's Rosetta spacecraft on June 6, 2014. The detection of water vapor has implications not only for cometary science, but also for mission planning, as the Rosetta team prepares the spacecraft to become the first ever to orbit a comet (planned for August), and the first to deploy a lander to its surface (planned for November 11).

EPA Proposes New Standards for Landfills, Hopes to Reduce Methane Emissions

Regulatory news - ENN - July 2, 2014 - 9:49am
As part of the President's Climate Action Plan – Strategy to Reduce Methane Emissions, the U.S. Environmental Protection Agency (EPA) is proposing updates to its air standards for new municipal solid waste (MSW) landfills. These updates would require certain landfills to capture additional landfill gas, which would reduce emissions of methane, a potent greenhouse gas, and help further reduce pollution that harms public health.

New research reveals causes and warning signs of rare tsunami earthquakes

Tsunami earthquakes happen at relatively shallow depths in the ocean and are small in terms of their magnitude. However, they create very large tsunamis, with some earthquakes that only measure 5.6 on the Richter scale generating waves that reach up to ten metres when they hit the shore. A global network of seismometers enables researchers to detect even the smallest earthquakes. However, the challenge has been to determine which small magnitude events are likely to cause large tsunamis.

The link between oceanic currents and climate

Climate Change News - ENN - June 29, 2014 - 9:19am
For decades, climate scientists have tried to explain why ice-age cycles became longer and more intense about 900,000 years ago, switching from 41,000-year cycles to 100,000-year cycles. In a new study in the journal Science, researchers found that the deep ocean currents that move heat around the globe stalled or even stopped, possibly due to expanding ice cover in the north. The slowing currents increased carbon dioxide storage in the ocean, leaving less in the atmosphere, which kept temperatures cold and kicked the climate system into a new phase of colder but less frequent ice ages, they hypothesize.

Endangered Species Act may be significantly weakened by new policy

Regulatory news - ENN - June 28, 2014 - 8:52am
The Center for Biological Diversity will file a legal challenge to an Obama administration policy, finalized today, that severely limits when a species qualifies for protection under the Endangered Species Act - a change that ignores both broad legal precedent and congressional intent. Under the Act a species qualifies for protection when it is "in danger of extinction in all or a significant of portion of its range." Both Congress and the courts have explained that the "significant portion of range" provision is vital for important conservation because it allows federal wildlife agencies to protect species before they are at risk of going extinct globally. But the newly finalized policy sharply restricts the use of this part of the Act, defining "significant" to mean that only when the loss of a part of a species' range threatens the survival of the whole species would wildlife agencies protect that species under the Act.
