The arguments for global warming can sound a bit vacuous when discussing temperature changes of only one degree. The impact of the melting Arctic ice cap on animals is much more tangible.
Animals and The Melting Arctic Ice Cap
There is little dispute that the Arctic ice cap is melting. Since 1979, it has definitively shrunk by 20 percent. The issue amongst most people debating global warming is whether this is because of global warming or just a natural cycle of the planet.
From a common sense point of view, it is difficult to imagine global warming is having no impact on the ice caps. The rising temperature of the planet would seem to be a common sense cause of the melting ice. Alas, common sense rarely seems to be used in debates these days.
As the cap melts, the impact on animals in the area is readily apparent. The primary problem is the reduction of habitat. Polar bears are the most obvious animals suffering from this situation. The habitat of the polar bears is the ice flow areas around the edges of the caps. As the caps melt, the flows are disappearing and pulling back to the extent that there is no ice on the shores. The extent of the melting is such that a Russian ship was able to reach the North Pole in 2005 without the use of an ice breaker. This lost habitat is pushing the polar bears to the edge of extinction. Various estimates put the total population at 20,000 and dropping.
There are, however, positive developments for some species. Recent empirical evidence shows the various seal populations of the Arctic are exhibiting growing population numbers. The exact reason is unclear, but they are appearing more and more in southern regions of the cap, which leads to the conclusion that their habitat is actually expanding.
The receding caps are also opening up extensive new habitats for fish. The melting ice is full of nutrients and fish migration to the new opening seas is astounding. Pink salmon, in particular is being seen spawning in rivers far to the north of their usual spawning grounds.
In general, the impact of the melting Arctic ice caps is a mixed situation. The polar bears certainly don’t see anything to be happy about.

Ancient Astronauts and Contemporary Skepticism
Over the course of the past year, I closely assisted a colleague in writing a series of ten articles covering diverse aspects of my ancient astronaut theory. All ten of those articles circulated widely around the globe and view counters on many sites indicated plentiful readership, but feedback to me, or to her, from anywhere, was non-existent. There was neither criticism nor acclaim from anyone. Just silence. I was starting to think that perhaps no one in world wants to take ancient astronauts seriously.
In an attempt to make some progress, I decided to pay sixty dollars for a review of my ancient astronaut website. Of course, this was to be a review by skeptics; a review by New Age believers would be worthless. Their blog's description was "critical reviews of paranormal claims on the Internet." The intermediary granted them five days to perform their review but that has long since come and gone, and not a word from them. My website presents a vast amount of evidence and, in truth, I could not expect anyone to produce a good critical review in just five days. No one, including myself, would want to see quickly prepared and frivolous arguments, else I would make them look ridiculous in my counter arguments. Moreover, some of my evidence comes from Spanish-language sources and, to start, they would need time to verify that none of it is a hoax. They are welcome to all the time they need.
What to expect from this blog is uncertain. There are skeptics who are as narrow-minded in their thinking as their New Age counterparts, and then again, there are skeptics, like me, who objectively evaluate the evidence to arrive at the truth. Was there a real ancient astronaut? To help the skeptics answer that question, I will give them some ideas on how to refute my theories. Here, solely for space considerations, I will concentrate on the archaeological evidence, leaving aside ideas on how to refute the cryptology and theology evidence for another day.
My website reproduces engravings from the Tiwanaku civilization in Bolivia. One of those engravings depicts the alleged ancient astronaut as an aquatic with a three-pronged tail, with each of the three prongs ending in a pod. How do the skeptics refute that? Easy. They simply need to demonstrate that the shape of those pods resembles some form of animal or plant life to be found in that region. In other words, they need to find a terrestrial source for those engravings, otherwise my extraterrestrial arguments remain unharmed.
The timing of the Tiwanaku sky-god drawings coincides with the timing of the Nazca Lines in Peru, so the ancient astronaut of both places has to be one and the same. For Nazca, the skeptics will find many ready-made arguments, but I consider all of them weak. The mentality of the people of Nazca cannot be assumed to be unique in human history. It has to be demonstrated that people elsewhere also believed that the sun, moon, or sky-spirits had physical eyes that could observe ground drawings. Alternatively, it has to be demonstrated that the people of Nazca worshipped birds, believing them to have cognitive intelligence.
The recorded engravings on the cosmological Sun Disk, alleged alien artifact, may prove to be the biggest challenge for the skeptics. How are we to believe that the Andeans of the early sixteenth century a) knew that the Earth was round, b) knew that it was possible to orbit the Earth, c) knew that sunlight striking the moon could reflect back to strike a spaceship, d) knew that the dark clouds along the Milky Way contained stars within, and e) knew that water formed the basis of plant and animal evolution? Here the skeptics would need to find parallels in the history of western civilization. I look forward to their response.

An Untapped Source Of Eternal Energy: What Is Solar Energy?
The most exact definition of Solar Energy is plainly – “the energy from the sun”. It is a term used to classify the electromagnetic radiation emitted by the sun and intercepted by the Earth. It is the world’s most permanent and reliable source of energy and the most copious.
The uses of solar energy on earth include solar heating for buildings, solar heat for manufacturing or industry and electricity production. So what is solar energy? How does it affect us?
Solar energy is responsible for weather systems and ocean currents. It provides light, heat, and energy to all living things on Earth. It has many uses. It supplies electricity; it can be used to power cars.
Solar energy is also used as a power for satellites in space and in space shuttles. It could also power boats, generators during emergencies, toys, and even security systems.
The amount of solar energy that the earth receives is about 770 trillion kilowatts (kW), an amount 5,000 times bigger than the sum of all other energy, may it be terrestrial nuclear energy, geothermal energy or gravitational energy.
There are two types of solar energy. These are:
1. Thermal Energy
2. Electric Energy
What is the difference between the two types energy?
Thermal energy is kinetic energy. It is everywhere. It makes the earth hot and even heats up our homes. It helps us to dry our clothes. It is used as well to heat up water for household use or even pools. That is why thermal energy is called the heat energy because it is stored in the center of the earth as well.
Electric energy is widely known to us as the electricity. It is an essential part of nature and it is one of our most widely used forms of energy. This uses sunlight to power ordinary electrical equipment, such as household appliances, computers, and lighting.
Most applications of solar energy depend on systems including collectors, storage and controls. Storage is needed for a reason that solar energy is only available at daylight hours, but the demand for energy is needed both day and night. Controls are used to guarantee that the storage system works safely and efficiently.
The accessibility of solar energy is determined by three factors:
• The location is usually measured by latitude, longitude and altitude.
• The time.
• The weather.
Aside from knowing that solar energy is a free energy still, you have to realize that it also has advantages and disadvantages.
The advantages are:
• Solar energy is almost limitless; it will be available for as long as there are still humans in the earth.
• It is abundant. You will not worry of running out of it.
• It could provide more power than all known fossil fuel reserves.
• Solar energy is available during the day when electricity usage is really important.
• It is the most inexhaustible, renewable source of energy known to man.
• Solar energy can be absorbed, reflected, transmitted, and insulated.
• It can be collected and stored in batteries.
The disadvantages are:
• It is not suitable in cloudy areas.
• It is not available at night time.
• And it may require large land areas.
As a reminder, solar energy levels are lesser the farther north the site. Considering geography, season is an important determinant of solar energy levels because the Sun’s position and the weather vary greatly from summer to winter.

An Overview of Wind Farms As An Energy Source
With energy issues becoming a daily subject in the news, wind energy is gaining notoriety. Here is an overview of wind farms and their potential.
An Overview of Wind Farms
A wind farm is simply a collection of wind turbines in a location used to produce electricity. Wind farms can be found in the United States, but are far more prevalent in Europe. China is also beginning to invest large amounts of resources in wind farms as its energy needs grow.
The fundamentals of electricity production through wind farms are pretty simple. Highly efficient wind turbines are placed in locations where they will receive the maximum amount of wind energy. These turbines can be traditional horizontal windmills or vertical eggbeater windmills.
Regardless, the wind turns the blades as it passes, which turns a generator within the turbine. The turning motion converts the wind energy into electricity when the generator cranks, which is then sent into a utility company power grid or stored in batteries. This process is similar to hydropower with wind being used instead of water.
The stereotypical wind farm is an exercise in topography. The goal is to find locations where wind exists as frequently as possible. Put in practical terms, ideal spots are in areas where ground variation occurs as wind is produced when different surface areas heat up at different rates. As each surface heats up, the air rises and cooler air rushes in to replace it. Thus, we have wind. Given this situation, ideal locations for wind farms are often along shorelines or in valleys funneling winds from the shore.
Many people are under the impression that wind farms are located only in areas of land where winds are howling through valleys and over hills. While this is certainly true, the current trend is to build wind farms off the shorelines of countries.
The advantage of offshore wind farms has to do with the frequency and generation of winds. Shorelines represent fertile wind generation areas. On top of this, the open space of the ocean allows winds generated from remote locations to move towards shorelines. If you have ever spent time going sailing, you have an understanding of how strong these winds can be. On top of all of this, placing wind farms in the ocean avoids the cost of buying pricey space on land.
Wind farms are up and functioning in most first world countries. The bigger issue is getting them to produce enough energy at as low a price as possible to make them a viable energy production platform.

Amazing New Hubble Pics
New Hubble pics - how exciting! The latest of the new Hubble pics is of a black hole, which they've captioned as being in need of a home.
To get these new Hubble pics a team of astronomers, all from Europe, combined the power of the Hubble Space Telescope with that of the VLT (Very Large Telescope at the European Southern Observatory (ESO) in Cerro Paranal.
The new Hubble telescope pics are of a bright quasar that has no discernible host galaxy. The new pics show several quasars, strong radiation sources. The astronomers honed in on these quasars to study them by way of the Hubble because they know that quasars are often associated with active black holes. Only one of the many quasars they found delivered a black hole without a galaxy. Thus the new Hubble telescope pics.
Other new pics show the other quasars that these European astronomers found. In one you can clearly see the black hole's host galaxy with its large spiraling tendrils.
In the past ten years the problem getting new Hubble telescope pics of black holes has been that the quasar shines so much more brilliantly than the host galaxy that observers can't always see, or get new pics of, the black hole and its galaxy. This problem has been resolved now so new Hubble telescope pics of host galaxies are possible.
With the recent observation of 20 quasars, 19 were found to have host galaxies. One did not. What this means is that if the host galaxy really does exist it has to be no more than one sixth the brightness of traditional host galaxies, or have a radius that is at least 20 times smaller than most host galaxies. New Hubble telescope pics of this find are being studied now.

Alternative Fuel Source - An Urgent Need For One
Using alternative fuel sources is not just a matter of environmental responsibility. It is not just about assuaging your conscience. It is good sense, and sound planning. Although most of us are in denial, the fossil fuels which form the backbone of our world economy are dwindling quite rapidly, even as we go about our daily business in our cars. Although few Americans use an alternative fuel source to commute, those who do are soon going to be at an advantage.
Alternative Energy And The Need For A Proper Storage Technology
A number of energy storage technologies have been developed or are under development for electric power applications, including:
* Pumped hydropower
* Compressed air energy storage (CAES)
* Batteries
* Flywheels
* Superconducting magnetic energy storage (SMES)
* Super-capacitors
