Global Warming is Not Cool !

Global warming definition

As it is obvious by its name, Global Warming is a global phenomenon with a number of effects on the global level. Global warming has various effects, ranging from the effects to the atmosphere to the economical, environmental as well as the health life of human beings.

The progressive gradual rise of the earth's surface temperature thought to be caused by the greenhouse effect and responsible for changes in global climate patterns. An increase in the near surface temperature of the Earth. Global warming has occurred in the distant past as the result of natural influences, but the term is most often currently used to refer to the warming predicted to occur as a result of increased emissions of greenhouse gases. “ ---definition of global warming from earthera website

Causes of Global Warming

Humans Are Causing The Problem:
While there are many natural causes of global warming , these causes do not account for the extra warming we are currently seeing on our planet. The current warming is anthropogenic, created by humans.

How do humans cause global warming?

We are accelerating the natural climatological cycles with our human-created emissions of greenhouse gases. The primary gas, carbon dioxide, is released every time you use fossil fuels- currently our main energy source. Unless you help stop those emissions, there is little hope of a secure future for humans.
You'll see that dangerous shifts in the Earth's climate are happening as we speak due to human induced global warming, and as it continues the consequences will worsen. Furthermore, such changes may be self-reinforcing. From an objective perspective, it looks like we are playing Russian roulette with all of life on Earth!

Natural causes of global warming:

1.Volcanic Eruptions
Large volcanic eruptions can throw so much dust into the sky that the dust acts as a shield to solar radiation and causes a cooling trend in the atmosphere. You probably can't remember such an eruption as they are rare and infrequent occurances.

Changes in the Earth's solar radiation levels can have some impact on the Earth's climate. Increased solar activity can cause short-term warming cycles on the Earth.

3.The Wobbly Earth
As the Earth spins, it does not achieve perfect rotation. It actually wobbles slightly, thus alternately exposing the northern and southern latitudes to more and less solar radiation. This wobble in the Earth's rotation has been causing changes in the temperature of the atmosphere for many millions of years.

Effects of global warming

Global Warming has many other effects such as cause a decline in agriculture due to the rise in temperature. The agriculture will also decline due to the role of carbon dioxide in photosynthesis. Carbon Dioxide prevents photorespiration and therefore is the cause of the damage of many crops.
Global Warming also results in increased number and longer droughts. This will result in a increase in the ozone gas at the ground level. The increase of the ozone at the ground level will result in a substantial depletion of crops. The increase in temperature will also cause various transport infrastructure like roads, bridges, ships to face greater temperature changes. Due to this, the maintainable costs of the transport infrastructure will increase. This may cause broken runways, malformed roads and sunken foundations. Global Warming also results in a rise in the sea levels. Therefore, this will result in an increase of the costs of the coastal defense. This is also dangerous, because the most important trade ports are always at the coast of any area for trade reasons. Global Warming will also have a effect on the daily weather. One of the most important effects is the increase in extreme temperatures. The levels of evaporation will also increase due to Global Warming.

Stop Global Warming

The future is not somewhere we are going. It is something we are creating. Every day we do things that make some futures more probable and others less likely
· Vote and influence your government with telephone calls, e-mails, letters and meetings with those who represent you in government.
· Choose vegetarian or vegan meals.
· Use compact fluorescent bulbs
· Use recycled paper.
· Count your carbon. Keep track of your carbon consumption as a way of tracking your progress
· Support producers of renewable energy.
· Insulate anything that uses energy to stay a different temperature from its environment.
· Use public transportation
Take responsibility for your office's energy use. Many offices leave air conditioners, computers and lights running all night. Work with responsible parties in your company to turn off these devices or use power-saving features when possible.
Try to consume fewer products to help conserve resources and control waste. Rent movies and video games instead of buying them, or buy them used, or at a garage sale. Check out books in the library or buy them used, or at a garage sale.
Planting trees balances carbon emissions and pollution. There are organizations that will help you offset your carbon footprint.
It is true that some scientists do not believe that global warming is caused by human activities or that it is even happening, but conserving energy and resources is good “insurance” for the climate.

As an individual you have more power than you can imagine to help solve this problem. You can make a big difference to help stop this unprecedented problem.
