Phases of the moon affect amount of rainfall
February 1, 2016 07:20 AM - Hannah Hickey, University of Washington

When the moon is high in the sky, it creates bulges in the planet’s atmosphere that creates imperceptible changes in the amount of rain that falls below. New University of Washington research to be published in Geophysical Research Letters shows that the lunar forces affect the amount of rain – though very slightly.

Why does the human brain respond more to sounds than language?
January 19, 2016 04:02 PM - McGill University via EurekAlert

It takes just one-tenth of a second for our brains to begin to recognize emotions conveyed by vocalizations, according to researchers from McGill. It doesn't matter whether the non-verbal sounds are growls of anger, the laughter of happiness or cries of sadness. More importantly, the researchers have also discovered that we pay more attention when an emotion (such as happiness, sadness or anger) is expressed through vocalizations than we do when the same emotion is expressed in speech. 

The researchers believe that the speed with which the brain 'tags' these vocalizations and the preference given to them compared to language, is due to the potentially crucial role that decoding vocal sounds has played in human survival.

How to make your new house a sustainable one
January 18, 2016 11:24 AM - Ewa Gromadzka

People might falsely believe that when they are building a house incorporating any sustainable solutions require additional costs and effort. It is actually the opposite. Some of the sustainable solutions require very little in any financing with comparison to the costs that need to be incurred anyways in a newly constructed building. Moreover, while an initial cost might be a bit higher as for purchasing, for example a sustainable heating system, there is a fast return on investment as utility bills are much lowers with sustainable heating than a standard one. It is possible to save around 30% on the use of energy and water in a sustainable house. That is a case with any other sustainable solution, when it pays off to invest in environment friendly solution in every case.
Below there is list of sustainable solutions that can be applied in every house.

  1. Heat recovery system for the ventilation, heating and cooling.
  2. The use of geothermal heat pump for heating the house, allows for great savings on heating costs.
  3. It is common to use only floor heating as a heating option in energy efficient houses (no radiators). 
  4. Use of low energy doors and windows (recommended triple glazed windows).

Cloud cover found significant factor in Greenland Ice Sheet melt
January 13, 2016 06:27 AM - University of Wisconsin-Madison via EurekAlert!

The Greenland Ice Sheet is the second largest ice sheet in the world and it's melting rapidly, likely driving almost a third of global sea level rise.

A new study shows clouds are playing a larger role in that process than scientists previously believed.

"Over the next 80 years, we could be dealing with another foot of sea level rise around the world," says Tristan L'Ecuyer, professor in the Department of Atmospheric and Oceanic Sciences at the University of Wisconsin-Madison and co-author of the study. "Parts of Miami and New York City are less than two feet above sea level; another foot of sea level rise and suddenly you have water in the city."

Recycling on the ropes, France has a plan to fix the industry
January 11, 2016 05:29 AM - EurActiv

Low raw material costs have dealt a heavy blow to the recycling industry. The French recycling federation (FEDEREC) believes the sector needs a complete overhaul to stay afloat in the coming years.

FEDEREC published its view of the future of recycling in a white paper entitled "The recycling industry by 2030." In the preface to this 70-page document, a frank discussion of the problems facing the industry and how they might be solved, Corinne Lepage, a Republican politician, evoked a sector "devastated by an oil price that is so low that it is driving us back towards a linear economy, as it is cheaper today to buy primary raw materials than recycled raw materials".

Natural carbon sinks and their role in climate
January 10, 2016 11:32 AM - Mark Dwortzan | MIT Joint Program on the Science and Policy of Global Change

Protected areas such as rainforests occupy more than one-tenth of the Earth’s landscape, and provide invaluable ecosystem services, from erosion control to pollination to biodiversity preservation. They also draw heat-trapping carbon dioxide (CO2) from the atmosphere and store it in plants and soil through photosynthesis, yielding a net cooling effect on the planet.

Determining the role protected areas play as carbon sinks — now and in decades to come — is a topic of intense interest to the climate-policy community as it seeks science-based strategies to mitigate climate change. Toward that end, a study in the journal Ambioestimates for the first time the amount of CO2 sequestered by protected areas, both at present and throughout the 21st century as projected under various climate and land-use scenarios.

Lawrence Livermore Laboratory developing underground battery system to store energy and CO2
January 6, 2016 04:30 PM - Lawrence Liverpool Laboratory.

Meeting the Paris Climate Agreement goal of limiting the increase in the global average temperature to well below two degrees Celsius compared to pre-industrial levels will require increased use of renewable energy and reducing the CO2 intensity of fossil energy use.

The intermittency of when the wind blows and when the sun shines is one of the biggest challenges impeding the widespread integration of renewable energy into electric grids, while the cost of capturing CO2 and storing it permanently underground is a big challenge for decarbonizing fossil energy.

However, researchers from Lawrence Livermore National Laboratory, Ohio State University, University of Minnesota and TerraCOH, Inc. think they’ve found an answer to both of these problems with a large-scale system that incorporates CO2 sequestration and energy storage.

 

US Files Complaint Against Volkswagen, Audi and Porsche for Alleged Clean Air Act Violations - not the kind of German engineering the VW Group wants to be known for
January 4, 2016 03:56 PM - US Environmental Protection Agency

The U.S. Department of Justice, on behalf of the U.S. Environmental Protection Agency, today filed a civil complaint in federal court in Detroit, Michigan against Volkswagen AG, Audi AG, Volkswagen Group of America, Inc., Volkswagen Group of America Chattanooga Operations, LLC, Porsche AG, and Porsche Cars North America, Inc. (collectively referred to as Volkswagen). The complaint alleges that nearly 600,000 diesel engine vehicles had illegal defeat devices installed that impair their emission control systems and cause emissions to exceed EPA’s standards, resulting in harmful air pollution. The complaint further alleges that Volkswagen violated the Clean Air Act by selling, introducing into commerce, or importing into the United States motor vehicles that are designed differently from what Volkswagen had stated in applications for certification to EPA and the California Air Resources Board (CARB).

“With today’s filing, we take an important step to protect public health by seeking to hold Volkswagen accountable for any unlawful air pollution, setting us on a path to resolution,” said Cynthia Giles, assistant administrator for enforcement and compliance assurance at EPA. “So far, recall discussions with the company have not produced an acceptable way forward. These discussions will continue in parallel with the federal court action.”

“Car manufacturers that fail to properly certify their cars and that defeat emission control systems breach the public trust, endanger public health and disadvantage competitors,” said Assistant Attorney General John C. Cruden for the Justice Department’s Environment and Natural Resources Division. “The United States will pursue all appropriate remedies against Volkswagen to redress the violations of our nation’s clean air laws alleged in the complaint.”

Is the Pope right on climate change?
January 2, 2016 11:26 AM - Robert N. Stavins, Albert Pratt Professor of Business and Government; Member of the Board; Director, Harvard Project on Climate Agreements

Last June, Pope Francis released his much-anticipated encyclical on the environment, Laudato Si’, which received tremendous praise from diverse quarters. The same day, Coral Davenport, writing in the New York Times, noted that the papal encyclical "is as much an indictment of the global economic order as it is an argument for the world to confront climate change." Ms. Davenport quoted me (accurately) as saying that elements of the encyclical were unfortunately "out of step with the thinking and the work of informed policy analysts around the world." In this column, I will elaborate.

First of all, the Pope is to be commended for taking global climate change seriously, and for drawing more world attention to the issue. There is much about the encyclical that is commendable, but where it drifts into matters of public policy, I fear that it is — unfortunately — not helpful.

The long encyclical ignores the causes of global climate change: it is an externality, an unintended negative consequence of otherwise meritorious activity by producers producing the goods and services people want, and consumers using those goods and services. That is why the problem exists in the first place. There may well be ethical dimensions of the problem, but it is much more than a simple consequence of some immoral actions by corrupt capitalists. The document also ignores the global commons nature of the problem, which is why international cooperation is necessary.

How many trees are on planet Earth?
December 26, 2015 09:33 AM - NELL GREENFIELDBOYCE, NPR

Here is a pop quiz: How many trees are on the planet?

Most people have no idea.

A new study says the answer is more than 3 trillion trees — that's trillion with a T, and that number is about eight times more than a previous estimate.

Thomas Crowther was inspired to do this tree census a couple of years ago, when he was working at the Yale School of Forestry and Environmental Studies. He had a friend who was working with a group with an ambitious goal: trying to fight global warming by planting a billion trees. A billion trees sounded like a lot. But was it really?
