Norway: cold wave last weekend froze School of fish

The waves of cold have multiplied all over the northern hemisphere in recent weeks. The last country to be reached was that Norway, last weekend, faced lower temperatures than normal.

Temperatures dropped enough to freeze a shoal of herrings on Lovund coast. According to Aryl Slotte, specialist in pelagic fish of the Marina Norway Research Institute, the animals will have been forwarded to shallow waters by cormorants, a predator of these animals. Prevented from swimming to deep water, with less likelihood of freeze, the fish ended up trapped and froze near the coast.

Seawater freezes at temperatures of -1.9° C, a temperature slightly lower than fresh water. According to the Norwegian Broadcasting Corporation, the public broadcaster, in temperatures -7.8° C reached Lovund last weekend and were accompanied by strong winds, the Huffington Post.

In January 2012, about 20 tonnes of herring washed up on a beach in Northern Norway. Scientists found no apparent cause for the death of the fish, but the possibilities include oxygen deprivation, illness or storms, causes that can easily cause the death of fish on the high seas, which are later dragged ashore by currents.

Remember that recently, also in Norway, a frog woke up too early due to the mild climate, having died when the ice came back.

Portuguese project creates a map of the biodiversity of the Serra da Estrela (with video)

Green Savers was the first information sites to make known the GeObserver, a portal that gathers data from weather, fauna, flora, demographics, hydrography, elevation and Serra da Estrela buildings of the last 30 years.

After 18 months, the green economy was visiting Paulo Barbosa and realize, in fact, how does the project. "The platform collects data from public and private weather stations, in real time. We also have people on the ground to collect data, which are checked by technical experts in each area. Ordinary people can also go to the site and record anything you can see or photograph of biodiversity ", explains Paulo Barbosa.

With the help of the photographs sent in by citizens, the GeObserver makes the confirmation of information and, from that moment on, starts building the biodiversity map of Serra da Estrela.

The main objective of GeObserver is to use these data for environmental protection, by which the platform received the help of a very special partner, the Association Friends of the Serra da Estrela.

"Very few people know who owns the Park in terms of biodiversity, whether of fauna and flora. There is a generic survey, but [the management] of everyday life has not been made. And you can only save what is known, "said the green economy Jose Maria Saraiva, Mountain Association.

In the short and medium term, the GeObserver will have to get new support to the network of information is not lost. One of the main achievements of this cross-was the creation of an index of risk of fire, which helps Civil protection and other local authorities to prevent to the heights of the hottest year. Thus, the public interest is visible.

The success of the platform will be able to take it in the short term, for other stops. According to Paulo Barbosa, have already made some contacts with Portuguese-speaking countries, who are interested in GeObsever to manage, more efficiently, its gigantic natural parks.

Like Green Savers had already in advance, one of these parks is the Gorongosa. See the episode 184 of the green economy.

Older trees grow at a rate greater

Trees increase the pace of growth as they grow older, according to a new study published yesterday in the journal Nature.

"The trees continue to grow so intense during its life cycle," said Nate Stephenson, study leader and forest ecologist of the US Geological Survey, in Three Rivers, California.

The research studied 403 species of trees from around the world and concluded that these never suffer from problems of old age. In animals, the change and ageing of cells will ultimately determine his death. But the trees do not have identical problems, only diseases, insects, the man, fire or accidents â€" like lightning â€" the can kill.

"They never stop growing. Each year that passes, always weigh more than in the previous year ", explained Stephenson.

Until now, it was believed that the trees stop growing older as they were made. A 2010 study was the first to go against this theory, when concluded that the giant California trees continue to grow into the sky each year that passed â€" and at a pace always greater.

Was this example it took Stephenson trying to learn more about the growth of trees â€" and if this was connected to his old age.

The study evaluated more than 670 thousand tropical and temperate climates trees â€" about 90% of these grow increasingly larger rhythms. The oldest trees can grow to 600 pounds per year.

Dried fruits help reduce risk of obesity

Formerly, the nuts were considered too fat to be healthy. Currently, the dried fruits are fashionable and their benefits begin to be widely advertised and studies that come to prove the benefits of the consumption of these foods are multiplying.

A new study, conducted by American investigators concluded that the nuts can help control weight and to reduce the risk of obesity. According to researchers, study participants who ingested quantities of regular dry swipes â€" such as almonds, pistachios, walnuts and Brazil nuts-were between 37% and 46% less risk of becoming obese than those who drank less few amounts of dried fruit.

Frequent consumers of dry fruits are also less likely to have metabolic syndrome, a cluster of risk factors that are linked to heart disease and diabetes. "There is another study which indicates that there is an association between the ingestion of dried fruit and a low risk of obesity, as well as a less prone to suffering from metabolic syndrome", indicates Joan Sabaté, researcher of Loma Linda University in California, CITES Reuters.

Another study shows that people who ingested nuts regularly are less likely to die in the 12:0 am following the intake of these foods than people who do not consume nuts often.

While this conclusion may not fully indicate that the differences observed between those who like dried fruits and those who pass well without them are caused by these foods, researchers indicate that there is reason to believe that the dried fruit provides direct benefits to health.

Most nuts are high in unsaturated fat, which is a "good" fat when compared with the saturated fat found in animal products. The high protein content makes people who ingest feel more satiated, leading to a lower consumption of food less healthy. Furthermore, dried fruit contain other nutrients and plant chemicals that are beneficial to health, indicates Joan Sabaté.

For the study in question was analyzed the diet of 803 participants. In General, those who ingested significant amounts of dried fruit â€" about 16 grams per day â€" were weighing a little more than average. Those who took little or no nuts had a very above average weight and, in some cases, showed signs of obesity.

The body mass index (BMI)-relationship between weight and height â€" a healthy adult should vary between 18.5 and 24.9. People with a BMI between 25 and 29.9 are overweight and a BMI which exceeds the 30 is considered obese.

The volunteers in the study who consumed nuts regularly had an average BMI of 27 while those who ate little or no food of this type had a BMI between 29 and 30.

England: Government launches €7,2 million Fund for planting 4 million trees

Over the next two years should be planted four million trees across England, according to the Government's confirmation of that country to continue to fund the creation of new forests.

The trees will be planted through a Government Fund of €7,2 million ($ 23.2 million), which will create 2,000 hectares of new forests and woodlands. The Fund is part of a total investment of €36,2 million (US $ 117 million) for the creation of new forests and management and preservation of existing ones.

However, plans to plant 2,000 hectares of new forests fall short the objectives of the Government itself, which wanted to plant about five thousand new acres, according to the Woodland Trust.

According to the Minister of forests, Dan Rogerson, quoted by the Guardian, the forests are "a cherished natural resource" and "provide a valuable habitat for wildlife and natural areas for future generations to enjoy".

"Planting 4 million trees over the next year will help us to increase the forest area, which will benefit the wild life, improve the environment and help the economy to grow. The new forests constitute economic, social and environmental benefits, allowing the forest industry to create new jobs and increase their contribution to the nation's economic recovery, "said the Minister.

Portugal hit record for renewable energy in 2013

Portugal has reached a record level last year, with regard to the production of electricity from renewable energy sources. About 58.3% of the total electricity consumed in 2013 was produced from renewable sources, which represents an increase of 20% compared to 2012.

If it is only considered domestic production, the renewables contribution increases to 61.7%. In the Face of this increased production of renewable energy in the past year it was possible to reduce the share of imported electricity at about 2.8 times, according to Quercus, which translates into a decrease of 10% of the total electricity consumed.

The difference between the values in the last two years is explained by the weather conditions. According to Quercus, 2012 was a very dry year, 58% below average. In contrast, 2013 was a wet year, 17% above the average. Thus, the production of renewable energy from water resources, using the dams more than doubled in the last year.

Also the percentage of energy produced from wind farms increased by 2013, almost 20%. With regard to photovoltaics, the increase of the installed capacity in the country allowed an increase of 25% compared with the same period of the previous year. However, the electricity generated from solar energy still accounts for 1% of the total electricity consumed, "which shows a huge potential for growth," said Quercus in a press release in conjunction with the Portuguese renewable energy Association (Apren).

"2013 was a year in which demonstrated the advantage of Portugal have bet on its natural resources to produce electricity because, besides having prevented imports of fossil fuels and emissions of greenhouse gases, the fact that 60% of the electricity consumed from renewable origin be allowed to stabilize the price of this well, which is also important to help Portugal out of the crisis"says the Chairman of the Board of Learning, António Sá da Costa.

Bet on renewable save €846 million allowed

According to the two associations to produce electricity of renewable origin enabled save almost 850 million (R $ 2,731 .4 billion) in 2013: €806 million on imports of fossil fuels (natural gas and coal) and € 40 million in allowances for carbon dioxide. In total, the savings amounted to €846 million.

"The emissions associated with electricity production + totaled 13 million tonnes of CO2 in 2013, about 20% of the total emissions of greenhouse gases present in Portugal", indicate the Quercus and Learning. However, between 2012 and 2013 there has been a reduction in CO2 emissions of around 2.3 million tonnes, the statement. This value, a million tons due to reduced use of coal power plants.

To the Group's coordinator of energy and climate change of Quercus is necessary to "continue to invest in renewable energies and in energy efficiency allowing the recovery of the economy without burdening the environment." "For this we need an investment in awareness and proper planning of the energy sector also towards a desirable climate policy demanding".
