Solar Flares: US & China battle it out over solar tariff

Things are definitely heating up between China and the USA when it comes to the trade front. With both nations trying to safeguard their own business interests, it seems that there is a full-on battle between two economic giants.

This is of particular significance in a world where many nations are suffering from a downward economic spiral and are trying hard to prevent the slide. While the planet is turning towards alternate energy and renewable sources to reduce on both domestic and business electricity prices, and cut down on both emissions and bills, the field of solar energy and trade has become the latest trade battleground.

Recycling Mobile Phones

Every year in Europe, there is an impressive figure of 160 million mobile phones that are thrown. And of this number, only 1% is recycled properly. This data came from a study of the Renewal Device Forum. Mobile phones are part of the so-called WEEE (waste from electrical and electronic equipment).

A huge number of polluting technology which, if recycled and reused, could lead to savings of 1.5 billion euros on materials and 120 million in energy savings.

These huge numbers stress the lack of widely-used consumer products into the environment: “Few people return their phones at the end of its use, despite incentives, and (some) information campaign,” says an executive at Sony Mobile France.

How do we recycle? First of all, try to use your phones as long as possible. If they’re no longer working, however, confer them to the ecological islands (or recycling centers) in your municipality for recycling and recovery. The collection should always know what to do.

Australian Tree Frog (Litoria splendida)

 

Did you know?

That the males of Litoria splendida produce a substance that is released into the water to attract female species?

The Australian Tree Frog is a large tree frog that is 10 cm in length. It has dark olive color schemes to bright green on its back, with yellow or white spots scattered. The inner surfaces of the forelegs, hind legs and groin are bright orange yellow. The belly is white and granular. A large gland completely covers the top of the head. The skin of the back is smooth. They have three fingers that are slightly webbed. The color of the species may vary depending on the region where they are.

The Litoria splendida breeds in the early rainy season with the onset of monsoon rains (December and January). A female lays eggs on average about 1,000, floating in groups and forming a single layer on the water surface. The larvae takes from 1 to 4 months to develop, depending on when the eggs were laid.

Facts About Nuclear Energy

Nuclear energy is a nonrenewable energy source. Read some interesting facts about nuclear energy.

– Nuclear energy is the energy that is liberated by the decomposition of a nucleus of two atoms or by combining two atomic nuclei into a new atom.

– At the moment, nuclear energy is derived from the conversion of mass into energy during the splitting of the atom. This happened after the famous formula, E = mc2, by Albert Einstein was introduced. The formula says: E [energy] equals m [mass] times 2 by c [c – speed of light]. That is, the released energy is equal to the difference of the masses multiplied by the square of the speed of light.

– Nuclear energy is increasingly referred to as acceptable energy source because it produces no greenhouse gases and the Earth is not heated, unlike other non-renewable energy sources.

– Nuclear energy is produced by a controlled chain reaction and creates heat. This heat is used for the heating of the water, the production of steam and for the operation of the whole turbine.

– Nuclear power plants need much less fuel than the power plants that use fossil fuels. For example, one ton of uranium is the same quantity of energy that can be gained from a few million tons of coal or several million barrels of oil.

– Nuclear energy is the nuclear fission of uranium, plutonium or thorium or the fusion of hydrogen atoms into helium. At the moment, most uranium is used.

– Nuclear energy was accidentally discovered by a French physicist, Henri Becquerel in 1896. He saw that a photographic plate was dark after it was stored in the dark next to the uranium.

– In the U.S., the nuclear power plants generate about 19% of electrical energy. This is equal to the total consumption of electrical energy in three most populous states: California, Texas and New York.

– On the 27th of June 1954, the Soviet Union’s first nuclear power plant is the Obninsk, where electricity was generated and was thereby connected to the electrical grid. It produced approximately 5 MW of power.

Where is the Earth’s Water Stored?

The earth from space is considered a blue planet. This is the color of the water that covers three quarters of its surface. Only the presence of water allows life. On Earth, water is abundant, with 1.4 billion cubic kilometers in total. However, the water on the earth is distributed unevenly. This is why there are many places where there is too much or too little water.

The total amount of water on earth is estimated at 1.4 billion cubic kilometers. Of these, 97 percent is good salt water, while only 2.75 percent (38.5 million cubic kilometers) is fresh water. Although our very early ancestors came from the oceans, the salty taste of our blood reminds us that the apple has not fallen far from the tree. However, we cannot we not live by salt water. We need fresh water.

A large freshwater is found on the Antarctic ice, with a total of about three-quarters of the fresh water (29 million cubic kilometers) in glaciers and ice sheets bound. The 98.5 percent of the liquid fresh water (9.5 million cubic kilometers) is stored as groundwater in the cavities of the lithosphere . And only a small part of it, the small amount of 144,000 cubic kilometers or 0.0001 percent of all water on earth is easily accessible in rivers and lakes, soils, living organisms, and in the atmosphere.

Plain Anoa (Bubalus depressicornis)

Did you know?

That Anoas are the world’s smallest cattle? They are often called dwarf buffalo, which is its closest relative.

The Plain Anoa is a species of small cattle with plump body, a thick neck and short legs that are delicate as those of the antelopes. The head to body length is 170-190 cm, while the shoulder height is 80-100 cm. The Plain Anoa weighs up to 300 kg.

The Bubalus depressicornis has a coat that is short and almost bare (woolly in juveniles). The color is dark brown or black, with lighter underparts. Females may be lighter in color than males. The legs are white or yellowish white from the knees to the heels, with a black line on the front.

The Bubalus depressicornis have whitish color in several parts of the face and neck, such as the presence sometimes of a white crescent on the throat. The ears are medium in size and tip. The horns are short (20-40 cm) and straight, with a triangular cross section at the base. Their tails have a small bushy tip.

Maritime Consequences

Our oceans play a fundamental role in controlling Earth’s climate. This is because water is 1,000 times more dense than air and retains heat four times (this property is known known as “thermal inertia”). Oceans store large amounts of heat. Ocean currents transport heat around the globe, similar to the heating of a house. However, warmer seas also means the destruction of underwater ecosystems.

Rising temperatures are having a disastrous effect on the coral. In 1998, scientists announced that most of the coral is dying. In fact, large coral bands have disappeared from the coast of Florida.

Coral reefs are produced by tiny sea creatures called polyps. They have hard external skeletons made of calcium, which over the years, help to form large colonies. The coral forms around the world in warm waters over 20 degrees Celsius and generally at depths below 50 meters. The Great Barrier Reef is the largest and most famous coral reef that exists.

It is estimated that over a quarter of all marine fish are found in or around coral reefs occupy only 0.02% of the world’s oceans. This could explain why coral reefs are sometimes called the forest of the ocean. This is because up to 15% of all global shoal of fish are caught here. This results in dire consequences for local economies. But this loss is much deeper.

Another immediate consequence is the melting of the polar regions, which will increase the proportion of freshwater on the planet, also the water level will rise to four inches every twenty years or so, affecting countries with very large coastal areas.

The barrier acts as a breakwater to provide protection to the islands and coasts of the violent storms of the open sea, particularly during hurricane season. Of course, the temperature of the ocean also generates hurricanes, storms more powerful and feared in the tropics.

Hurricanes are large low pressure rotors, large enough to be seen from space. They bring torrential rains, storms and strong winds. Hurricanes raise their path sea level and often cause flooding in low-lying coasts. This phenomenon is known as “storm surge” and can reach up to 4 meters high.

Conditions must be necessary for the formation of a hurricane, the sea surface must be above 26.5 degrees Celsius. To be classified as a hurricane, typhoon or cyclone, the wind speed must be greater than 117 km / hour. About 50 tropical storms each year reach hurricane status.

If the oceans warm up, that number could double. Tropical atolls like the Maldives, rising less than 1.8 meters above sea level, could disappear forever. Along with its population of 270,000 people.

Earthquakes and Tsunamis

Geologists believe that the rising sea level will have implications that could be added more decisive than the weather. The additional weight of millions of cubic kilometers of water could cause strain on the weakest points of the earth’s crust, known as the lithosphere by experts.

This could precipitate earthquakes and volcanic eruptions and geological faults that cause local devastation and would send harmful gases and debris into the atmosphere. There are also increased risks of tsunamis. These tidal waves are generated by undersea earthquakes and can travel thousands of miles around the ocean at speeds of 800 kilometers per hour. They appear without warning and with waves up to 30 meters high.

Geologists predict that the volcano on La Palma in the Canaries could explode at some point in the future. The result could send a mega tsunami 500 meters high across the Atlantic that could swallow parts of the UK.

Global warming is a global phenomenon. Continents, countries, municipalities and communities could be thousands of miles away, but no one lives completely isolated. The impact of man’s irresponsible behavior and the resulting natural disasters affect us and affect everyone.

Australian Sea Lion (Neophoca cinerea)

Did you know?

That the Lion of the Sea of Australia is the only species of pinniped endemic to Australia? It is also the least numerous species among pinnipeds in Australia.

The male Australian Sea Lion can reach a length of 2.5 meters and weigh 300 kg. The color of its skin is brown and grows darker as they mature. The female Australian Sea Lion are considerably smaller, reaching a length of 1.8 m and a weight of about 100 kg. Their skin is gray, silver, light brown, and belly is even brighter. 

The Australian Sea Lion breeding colonies are small, consisting of several hundred animals or less. However, except for the breeding season, they are usually antisocial. They do not migrate and spend more time ashore during molting (the renewal of the skin of the body). 

The breeding cycle is uncommon, lasting 18 months (compared with other seals, whose cycles last 12 months) and there is no synchronization between colonies. Australian Sea Lions are monogamous. They stay with one female for several weeks until they mate, then return to sea to feed and look to the next female. Gestation lasts about 12 months. If the female does not give birth in consecutive seasons, the babies can be breastfed until 2-3 years. Their diet consists of fish, octopus, squid and penguins from time to time.

Global Warming Threatens the King Penguin

The long-term survival of the king penguins in Antarctica is in danger. The reason? Global warming, rising water temperatures and the amount of prey that these penguins feed. This actually comes from a study of Hubert Curien, a Multidisciplinary Institute in France that is part of the French National Center for Scientific Research.

The species, second in size after the emperor penguins, have their habitat on the islands of the northern limits of the Antarctic. It is estimated that currently, there are around two million breeding pairs.

The food of these penguins are small fish and squid, which has begun to erode as a result of global warming. This is due to the high temperatures of the sea prevent these mammals inhabit the area.

The researchers suggest that every rise of 0.26 ° C in sea surface will lead to a 9% decrease in adult penguin population, which places the species at high risk. This is because the average temperature increase expected for the next two decades is 0.2 ° C.

Methane: One of the Causes of Global Warming

Methane is another extremely potent greenhouse gas, ranking next to carbon dioxide. Methane is produced when organic matter is broken down by bacterias that are under oxygen-starved conditions or anaerobic decomposition.

Anaerobic decomposition is also processed in the intestines of herbivorous animals. With the increase in the amount of concentrated livestock production, the levels of the methane gas released into the atmosphere also increases.

Methane clathrate, a compound that contains large amounts of methane that is trapped in an ice crystal structure is also another source if methane. As the methane gas escapes from the Arctic seabed, there will also be an increase of global warming’s rate.

Socorro Dove (Zenaida graysoni)

Did you know?

It is believed that the Zenaida Relief has been extinct primarily by cats? Also, the hunting and high levels of sheep grazing in the understory may have been factors leading to the extinction of the species.

The Zenaida graysoni is measured at 26.5 to 34 cm. It is a mainly terrestrial bird of average size, as reflected by tarsus length, and weighs about 190 g. The male has the head and lower parts of tan, with black stripes on the bottom of the ear. It has a blue-gray neck and iridescent pink patch on the neck.

The coloration of females and juveniles is slightly opaque. As this is common in birds of many islands who are isolated from natural predators, they show no fear of man. This species is also called “Lonesome Dove”.

The male Zenaida Relief seem to be very aggressive. The female lays two small captive white eggs in a nest box placed 1 to 2.5 m above the ground. Incubation takes 14-17 days. The young then leaves the nest after 14-20 days.
