There are seven million subscribers who enjoy Sky Television in their multitude of services: they have it all from cultural events and entertainment shows, movies and interactive opportunities, to news, sports and great documentaries at a high video and sound quality. Sky Television was founded as a four channel network in 1989 by Rupert Murdoch, but the company merged with its competitor British Satellite Broadcasting in 1990 and it became British Sky Broadcasting. Even after the merge, the company was still in serious financial trouble with millions of pounds being lost every week. The management reorientation and the introduction of the subscription system allowed for the gradual recovery of the losses and even the making of profit in the following years. The new Sky Television turned into a success.

Sky Television is the most important subscription-based TV service provider in the UK that enters around ten million of British and Irish homes. Sky Television is spread all over the UK, and although most of the services are concentrated in Livingstone and Dunfermline, Scotland, the headquarters remain in London and the uplink for the satellite at Southampton. Changes came over the years with modifications not only of the departments but of the packages offered to the consumers too.

The user gets access to the channels broadcast by Sky Television by means of the Sky digibox with or without personal video recorder included. If you choose the complex set, then it would be like having your own TV channel to enjoy freely. One other great option promoted by Sky Television in order to increase the number of customers is the use of interactive TV services, thus viewers could even select what cameras to watch through during sports events for instance. Besides the subscription-based services, Sky Television also broadcasts around 160 free to access radio and TV channels via satellite.

Global Warming is a term denoting a gradual warming of the Earths average temperature. The term has become synonymous to the Earths warming exclusively due to man-made effects, especially carbon dioxide. Carbon dioxide concentrations have increased from 300 parts per million to 384 parts per million since 1900, with the most accelerated increase during the past 40 years. Some scientists have drawn the conclusion that the increase in the Earths average temperature (about 1F since 1975) is essentially solely based on man-made activities such as the burning of fossil fuels, biomass burning, and deforestation.

Causes of Global Warming

The Earths atmosphere is made up of different gases. Nitrogen makes up 78% of the total composition, Oxygen 21%, Argon 1% and traces gases .1%. Carbon dioxide makes up most of the volume of the rare gases. Water vapor varies from almost 0% over the deserts to 4% over the oceans. Water vapor, carbon dioxide, methane, ozone, and nitrous oxide are the gases of interest since these are the greenhouse gases. Greenhouse gases can reradiate heat or trap heat absorbed by the Earth from the sun. Water vapor is by far the largest mechanism for heat retention out of the greenhouse gases.

In the past, the Earths orbital eccentricity, variance of the tilt and wobble have led to periods of warmer weather. Even though the solar energy from the sun is considered a constant, a slight change could cause temperature fluctuations. Recently, Mars has also shown a decrease in ice coverage without greenhouse gas changes. The cause for the reduction in aerial coverage is unknown.

In summary, there are three mechanisms which would cause global warming, or in other words allow for a warming of the Earths average temperature. These are: (1) solar energy variance, (2) gradual changes in the Earths orbit, tilt, and wobble, and (3) greenhouse gas changes. It is difficult to calculate what percentage of the recent warming could be attributed to human activities. We can eliminate changes in the Earths orbit, tilt, and wobble causing a temperature increase since these are long term effects.

What are the Effects of Global Warming on Hurricanes?

There is a common misconception that since the global temperature has increased, hurricanes also must increase in number and intensity. The primary factor in the ability of a hurricane to strengthen or weaken is the wind shear profile of the atmosphere – not water temperature. It always has been warm enough in the tropics to produce hurricanes. This temperature equates to a sea surface temperature of about 80F. If you study the behavior of hurricanes you can find cases where hurricanes have strengthened over cooler water and have weakened over warmer water. There may be a small "boost" to a hurricanes strength as it moves over the Gulf Stream, if upper air wind profiles do not change much. Some of the computer generated hurricane models have this bias built in and will rapidly strengthen a tropical cyclone if predicted to go over a warm pool of water.

The recent upturn in tropical cyclone activity was predicted long before Global Warming became a household name. The tropical
Atlantic has been known to vary in cycles, and this recent upturn was expected. If you were to compare the period from 1900 to about 1950, with the 1950s until now, you would find an actual decrease in the average number of hurricanes and their intensity. It also is noted that the upswing in hurricane numbers over the past ten years or more has been only in the North Atlantic basin. Other hurricane formation regions have not shown this same trend.

The Effects of Global Warming on Hurricanes: Summary

There has been a noted increase in the number of hurricanes in the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico since the mid-1990s. The long term average is that ten tropical storms will form per year,
of which about six will become hurricanes. Since the mid-1990s the average has been fifteen tropical storms, of which eight have become hurricanes. There has also been an upward trend in the concentration of the greenhouse gas carbon dioxide
due to mans activities over the past 100 years. During this time, hurricanes have gone through cycles where they have been more numerous, such as the cycle that we are in now. Some scientists have drawn a one to one correlation between the Earths temperature increase and the number of hurricanes and their intensity. As we have noted, the number one factor in tropical cyclone intensity is related to the atmospheric wind shear profile. There is even some research that suggests that higher temperatures could
actually increase the wind shear profile resulting in a decrease in hurricane activity. The upward cycle in hurricane numbers is expected to continue for several more years. If this trend were to continue for a considerably longer period, only then could one draw a conclusion that warmer temperatures have played some part to cause an increase in tropical cyclone formation.

There are lots of things or actions we could do during heat wave. If it happens, better be safe.One of the important thing is to keep calm. Being calm will keep you active and take decisions wisely. This will not create anymore problem unlike you will try to do some strenuous activity. Another thing you could do is stay indoor most of the time. This at least will not directly heat your body with some hazards and heat caused by heat wave. Keeping your body cool at the times is a good way.

Drinking plenty of water is a very good way. This cools your body and refresh your mind. Water is the best liquid to take during this heat wave scenario. Try not to drink alcoholic liquids or caffeinated liquids. These can contribute to the heat on your body, which in turns can add to the dizziness you may feel. Try also to avoid food or meals creating or increasing your metabolic heat. Light clothing also helps during this heat wave.

During this heat wave, never leave your children unattended or don’t leave them outside. Animals or pets also needs to be taken cared off. They should be at least on a shady or not directly on the suns heat.

Don’t panic otherwise others will just panic like you. Try to bring the person under heat stroke into some cool place. Keep the body cool by rubbing or wrapping some wet sheets or clothing. Check breathing and pulse for some problems during the period of attack. Keep the person cool and lying until the emergency team arrives.

Heat exhaustion is another thing that can happen to a person during heat wave. When this happens let the person lie down and cool it by rubbing or wrapping with a wet sheet or clothing. Call for medical officers while giving the first aid. Fan the person experiencing heat exhaustion. Give enough water to sip or drink for the person to relieve for the body heat. Don’t drink water in an instant, keep it on a normal instance. It is better also to loosen the clothing he or she wears.

Heat cramps usually happens also during excessive heat. As above, take the person to a cooler place. Make the person relax by giving him a half glass of water every 15 minutes. Stretch lightly the affected area or muscles. Massage lightly to relieve pain.

We take in oxygen and breathe out carbon dioxide (CO2)
and emissions from factories, cars, and mining
operations are but a few of the sources of CO2.

The CO2 gases get trapped in the earth’s atmosphere,
causing unhealthy air that simply has no where to go.
The effect that each of us has on the environment is
called our Carbon Footprint.

Many factors contribute to our individual carbon
footprint, including where we live, the size of our
home, how old our appliances are, what we drive and
how much air travel we do.

While there is no way to eliminate our carbon
footprint to slow climate change; there are things we
can do to reduce the size of our “shoe”.

In order to reduce our carbon footprint, we must first
know what size we are. There are carbon calculators
online (www.carboncounter.org) that are simple to use
and will quickly show you how much your carbon burden
is.

By knowing what our personal impact is, we can then
work on reducing it. There are many organizations that
continually endeavor to offset and mitigate the
damages by CO2 emissions, including wind power,
reforestation projects and solar power projects,
including Conservation International, Nature.org and
Carbon Counter.org.

Working together to individually reduce our personal
carbon footprint can only be good for our planet, our
future and the future of generations to come.

These holes in the atmosphere allow the sun’s rays to
enter the earth without a protective layer to shield
us, which may cause an increase in skin cancer.

CFCs are an aggregation of chemical compounds that
include alkanes and haloalkanes. These chemicals are
used in aerosol spray cans, refrigerants, foam blowing
(to make packing foam and foam cups), fire
extinguishers and solvents to clean electronic
equipment.

The use of CFCs began in the 1920, when carbon
tetrachloride was used in fire extinguishers, until
the end of World War II. In 1928, Thomas Midgley
developed CFCs as a replacement for a mixture of
ammonia, chloromethane and sulfur dioxide that was
commonly used as a refrigerant.

The CFC was superior to the former compounds because
it was non-toxic, had a low boiling point and was
generally non-reactive.

CFCs continued to be used, mostly by the military and
in firefighting, until 1974 after the journal, ¬Nature
by Molina and Rowland, showed their findings regarding
the ozone layer depletion. They won the Nobel Prize in
Chemistry for that work.

They found that by adding hydrogen and creating
hydrochlorofluorocarbons (HCFC), made the compound
less stable in the lower stmosphere, which meant they
would break down before they reached the ozone layer.
Eventaully, the chlorine would be taken out, creating
HFC with an even less stable compound.

Scientists show that the decreases in CFCs have been
helping the ozone layer, particularly over Antarctica,
and predict that that particular hole will close
permanently by the year 2050.

According to Merriam Webster Dictionary, two of the
definitions of the word theory include: the analysis
of a set of facts in their relation to one another;
and a plausible or scientifically acceptable general
principle or body of principles offered to explain
phenomena.

There are many “facts” about the earth’s atmospheric
changes; many scientists believe we are experiencing
the start of a warming cycle that could change the
climate so dramatically that humankind would cease to
exist.

Other scientists, using the same data, draw vastly
different theories: the atmosphere is experiencing a
harmless blip in its natural and normal cycle and that
humans only minimally affect the amount of CO2 in the
atmosphere.

There is vast evidence on both sides of the argument,
and there seems to be very little middle ground. Al
Gore’s “Inconvenient Truth” and Spencer R. Whert’s
“The Discovery of Global Warming” came to the
forefront in warning us about global warming; Fred
Singer, former Chief Scientist with the US Weather
Program and Professor Wilfred Beckerman, former member
of the Royal Commission on Environmental Pollution are
just a few of the scientist who view the data from the
opposite angle.

There are innumerable articles, papers and books that
support both sides of the global warning issue. The
only common ground in these opposing camps seems to be
that the data fails to back enough years to be
absolutely indisputable, and that, as good as they
are, computers cannot model nature.

Earth Day came about after six years of effort from
then Senator Gaylord Nelson, who, back in the 1960s,
had the foresight to look at the long term impact of
pollution on the environment. He was instrumental in
getting his message out to college students, who took
this issue on with concern and enthusiasm for this
project. Earth Day became a National Awareness day on
January 20, 1970, with the date set for celebration as
April 22 of every year. In 2007, it is estimated that
one billion people recognized Earth Day in some way.

Internationally, Earth Day is celebrated at different
times, in approximately 175 countries. In the northern
hemisphere, it is observed in the spring; in the
southern hemisphere, Earth Day is observed in the
fall.

The purpose of Earth Day was to raise awareness of
environmental issues, promote education about the
issue, and to advocate for a healthy and sustainable
planet. Many schools have taken Earth Day a step
further to incorporate extended teaching of
environmental issues and observe Earth Week.

To find events in your area, or to get ideas for
helping you commemorate this special day, go to
www.earthdaynetwork.com. Get involved in helping in
your community, whatever the needs may be. Every city
has a park, street or stream that needs cleaning up,
and it takes only a few volunteers to make a huge
difference. Take the time to learn about how you can
help preserve this planet for future generations. They
will thank you for it!

The earth has immense forests, which play an important
part in the sustainability of habitation. Trees and
plants take in carbon dioxide and give off oxygen in
the spring and summer; in the fall, they drop their
leaves which give off carbon dioxide. This cycle seems
to keep the CO2 (carbon dioxide) levels in the
atmosphere balanced throughout the year. If only
human’s could have this impact!

Without leaf cover, the albedo (surface reflectivity)
changes; what used to be lush and green (rainforests)
becomes dry and reflects the rays of the sun back up
into the biosphere, trapping heat. Without the forests
creating oxygen, the balance in our atmosphere becomes
tenuous. The balance of the gases in the earth’s sub
stratosphere is delicate, and their stability is of
great importance to anyone who needs air to breathe.

Human activity, like cutting down forests and
overgrazing land, can change the climate, not only
where it is happening, but around the world. Rising
temperatures in the atmosphere have long-term effects
on the ocean and the polar icecaps which have the
potential for wreaking havoc with the climate
worldwide.

It is of utmost importance that the forests worldwide
are protected; by protecting this vast resource, we
protect our planet and our future. Plant trees!

Simple things that we do, or don’t do, have an effect
on our planet’s precious atmosphere. How many times a
week do you go to the coffeehouse and get your coffee
in a paper or cardboard cup? You might have thought
about how many years it takes for that cup to
decompose, but have you thought about the energy that
went into the production and transportation of that
cup? Multiplied by…?

Do you reduce, re-use and recycle? Make it a goal to
reduce the amount of garbage you produce by recycling
and composting. Your town office or city hall will
provide you with a list of how to separate your items
for recycling. Every item that you can re-use or
recycle is one less item in the landfill.

One of the simplest ways to help is to purchase and
use cloth shopping bags. The hard part is remembering
to take them out of the car and into the store, but
once you get into the habit, it becomes second nature.
Resolve to not accept plastic bags in a store.

Traveling in a gas-powered vehicle as little as
possible is a great way to conserve. Walk or bike
whenever and wherever you can; it’ll help the planet
and your health. If you live in the city, use public
transportation. Likewise, if you live in the country,
carpool to work and instead of making several trips a
week to run errands, save them for one trip.

If you take the time to think about your daily
activities, and how you can do them a little
differently, you may find yourself not only helping
the environment, but helping your wallet. Do only full
loads of laundry and dishes; cut your shower by two
minutes; switch to energy-saving light bulbs; turn
your refrigerator and air conditioner up a single
degree and turning off your electronic devices at
night are all painless ways to help.

Challenge yourself to think before you act for a few
days and you will surprised at how easy it is to begin
the process of going green.

There has been much research in the area of solar
power, tapping geothermal heat inside the earth,
harnessing the power of the tides as an energy sources
and wind turbines, but scientists are going further
into their imaginations to develop energy from sources
never thought of before.

For instance; scientists are studying marine algae in
the hopes that they could generate power from the
methane given off by rotting algae; the methane could
then be harnessed to provide methane for burning to
power industrial needs for energy. Corn is being
tested as a fuel (ethanol) for cars, as well as home
heating sources, and there are many other areas that
you may not have thought about.

Early studies are looking at falling rain and how it
might be used to generate power (same premise as
harnessing wave power). I’m not a scientist, so I
can’t even begin to explain how or why this might
work.

The idea I like best is powering our own personal
IPod, cell phone and home computer by walking power. A
leg brace, equipped with an electricity generator,
gets the power from your every step. Need it charged
quickly? Go for a long run; need a little power to
power my laptop to get me through the meeting, go walk
an hour!
