Global Warming Sketch

the chosen water drop represents the melting earth and some of the factors which are having a contribution towards it,reflect on this water drop.

Global Warming

There are a great number of factors that have contribution towards increasing global temperature, of which I would like to mention; the rise in atmospheric greenhouse gases which has been brought about by human activity and is the process by which absorption and emission of infrared radiation by atmospheric gases. Not to mention that, the concentration of various greenhouse gases are being involved in increasing radiative forcing from CO2, methane, tropospheric ozone, CFCs and nitrous oxide on the part of the human activity.

Besides, the carbon dioxide released by burning of fossil fuels in electricity generation and the burning of gasoline in internal-combustion engines of cars and other vehicles of which the ones with poor gas mileage contribute the most to global warming issue. While

, The carbon dioxide created by airplanes and building are relatively 3.5 percent of global warming and 12% of carbon dioxide emissions.

However, Methane is more than 20 times as influential as CO2 at trapping heat in the atmosphere, based on IPCC.

The most prevailing and the most powerful green house gas on the planet is the water vapor and it has been increasing as a result of the other greenhouse gases. it simply cause increasing cloud formation reflecting heat back out into space.

Nitrous oxide, which is naturally produced by oceans and rainforests, is another green house gas and is being broken down in the atmosphere by chemical reactions creating sunlight.

Burning and cutting of approximately 34 million acres of trees each year cause Deforestation, which is the second principle cause of atmospheric carbon dioxide.

Permafrost solid structure of frozen soil which has been turned out to be a soft material causing subsidence and damages to buildings, electric generating stations, pipelines and other structures. The director of the global resource information database in Arendal,Norway said:” Permafrost has acted as a carbon sink, locking away carbon and other greenhouse gases like methane, for thousands of year. But there is now evidence that this is no longer the case, and the permafrost in some areas is starting to give back its carbon. This could accelerate the greenhouse effect.”

Global warming has been causing lots of consequences towards earth, such as the changes in agricultural yields, trade routes, glacier retreat, species extinctions and increases in the ran earth’s climate changes, changes in solar luminosity, volcanic eruptions.

Moreover, the rise in sea levels and the changes in the amount and pattern of precipitation which are causing flood or drought.

The elements I used for my “Calendar” are three pumpkins, bats and a castle, by which I tended to create a combination leading towards the dates and also the description with a witch who is watching it.I used both Black and Orange color, which are symbolized as death, autumn, pumpkins, night, witch, bats, and vampires.

Assignment Two:"Halloween"

“ Halloween”, which is being felicitated every night of October 31 in many parts of western world especially in Ireland, the U.S. and Canada.
This celebration had brought to western countries by Irish and Scottish in 19th and 20th century, which has its roots in the ancient Celtic festival, when everybody celebrated their new year by wearing masks and costumes.
There is a belief that, on October 31, the dead enters to their world and causing them problems and damages, therefore people wear masks in this night, in order to stand against them.
“Halloween” is included of lots of symbols such as the carved pumpkin with a candle inside, monsters, ghosts, witches, vampires, skeletons, bats, and black cats.
Besides, the main two colors which are Black and Orange to indicate night, witches, bats and jack o’ lanterns, autumn, fire
