Even more about Global warming

· Global Warming is basically just the increasing temperature of the Earth’s average surface temperature. There are many reasons of global warming; two of such reasons are when we burn oil or fossil fuels we produce carbon dioxide and deforestation, which results in lesser trees taking in carbon dioxide which means ,that there will be a higher amount of carbon dioxide than before. Carbon dioxide would “eat up” the Earth’s atmosphere and the sun’s rays would be able to get through and they would burn or melt anything it comes into contact with as there is no longer a “layer” ,to reduce the severity of the sun’s rays. Scientists are arguing about how fast the Earth is warming up and for how much will it warm up.
· If global warming continues and the temperature increases, ice bergs will melt and the sea level would increase. Some plants and animals would become extinct as the rising sea level flooded it’s original habitat. Some animals would simply just move their houses to a new location. Islands would also become submerged in the water and the cities on the island would be totally destroyed and uninhabited, so we are all in big trouble if global warming does not stop. Scientists say that it is impossible to stop global warming at this stage of time but it would be still possible to minimise the damage done.
· The green house effect is the rise of temperature in the Earth’s atmosphere as certain gases; Carbon Dioxide, Nitrous Oxide, Methane, and Water Vapour (just to name some) trap energy from the sun just like a plant’s greenhouse and it acts somehow the same. Without the green house effect, the Earth would be about 60ºF (Fahrenheit) colder and the Earth is currently about 1ºF warmer than usual. As the green house effect may make you think that it is a horrible thing we can do without, we can’t, as it makes the Earth warm enough for humans to live but too much of anything is never good.
· Some may be asking, so what’s the big deal? It’s just the climate going up by 1ºF only, but even a slight temperature change can change the Earth. The last ice age, which was about 18,000 years ago, was just 7ºF lower than the temperature today, so just a little change can melt the total ice age. If you still don’t get it, think of it like not brushing your teeth for one day and is fine but not brushing your teeth for months will make a cavity, so the Earth’s temperature increases by a little on a day, big deal it’ll just go back to normal after a few days, but if it goes on ,the Earth would become hotter and hotter everyday.
· Warmer climates in cold countries would be welcome as more crops could be grown but too much heat will cause heat stress and may become a serious condition if not treated, you will get heat stress only when there is a very hot climate around you everyday, so imagine every single of us having heat stress; we would all die sooner or later as hospitals do not have so many vacancies.
· Weather describes whatever is happening outdoors in a given place at a given time. Weather is what will happen from minute to minute. The weather can change a lot within a very short time. For example, it may rain for an hour and then become sunny and clear. Weather is what we hear about on the television news every night. Weather includes daily changes in precipitation, barometric pressure, temperature, and wind conditions in a given location.
· Climate describes the total of all weather occurring over a period of years in a given place. This includes average weather conditions, regular weather sequences (like winter, spring, summer, and fall), and special weather events (like tornadoes and floods). Climate tells us what it's usually like in the place where you live.
