Weather is the condition of the atmosphere in one place during a short period of time . Climate: The term for weather patterns that an area typically experiences during a long period of time. Weather & Climate depends by the amt of direct sunlight a place receives. I .The Greenhouse effect A small amount of the sun radiation reaches the Earth’s atmosphere ,the rest is reflected back into space. With enough radiation ,there is warmth for the earth’s land & water. Day and night ,seasonal change, and differing climates all depend on the relative positions of the sun and the earth. II. Earth’s tilt and rotation Earth’s axis : an imaginary line that runs through the center between the North Pole and South Pole .The Earth’s axis is tilted at a 23 1/2°° angle .The Earth’s tilt affects the temperature of places .The Earth rotates, or spins, on its axis . The Earth makes one complete rotation every 24 hours ,causing day and night. III. Earth’s Revolution The Earth travels in an orbit around the sun ,which is also called revolution .It takes one year to complete the revolution . This causes changing seasons and the amount of daylight during the year. Equinox :the day (march 21)in which the sun is directly over the equator and the days and nights are equal in length. Solstice : the day in which the direct rays of the sun strike the latitude 23 ½°N

I.Process Most of the energy that the Earth recieves comes in the form of energy from the sun ,called radiation. This energy is electromagnetic radiation in the form of visible light ,composed of small amounts of Infrared and Ultraviolet.This
visible solar energy passes right through the Earth’s atmosphere.The Earth’s surface absorbs this energy and redirects it back into the atmosphere as Infrared ,with some going straight back into space.However ,as some of the Infrared radiation is being redirected it is absorbed by greenhouse gases (CO2, H20 and CH4) and sent back towards the Earth’s surface as heat, causing warming known as: The Greenhouse Effect. II. foundation The greenhouse effect was discovered by Joseph Fourier in 1824, first reliably experimented on by John Tyndall in 1858, and first reported quantitatively by Svante Arrhenius in 1896.
III.After – Effects
Global warming, a recent warming of the Earth's surface and lower atmosphere, is believed to be the result of a strengthening of the greenhouse effect mostly due to human-produced increases in atmospheric greenhouse gases.
The 2 major effects of global warming are:
Increase of temperature on the earth by about 3° to 5° C (5.4° to 9° Fahrenheit) by the year 2100.
Rise of sea levels by at least 25 meters (82 feet) by the year 2100.
Details:The effects of global warming are causing a broad range of changes:Sea levels rising due to the melting of land ice. Amounts and patterns of precipitation are changing ,causing the increase of frequency ,duration and intensity of extreme weather events such as hurricanes ,floods ,droughts and tornadoes.Other effects of global warming consists of species extinction ,further glacial retreat ,agricultural production ,major widespread diseases.
Warming is predicted to continue past the year 2100 since Carbon Dioxide (CO2) has a lifespan of 50 to 200 years.
~Personal Opinion~
From my point of view, global warming is nonetheless a worldwide phenomenon that has the possibility of affecting or producing great changes to humanity’s way of living, either for better or worse.
Taking into account the predictions of future results of global warming such as the rise of sea levels due to the melting of land ice ,major widespread diseases , changes in the amount of precipitation,…by the year 2100 ,then global warming certainly poses a great threat to mankind.
However, some people still say that there is no potential danger in this matter, and that this is just one of the process of the natural cycle. There was a period extending from the 16th century until the 19th century called the “mini ice age”, of which the temperature dropped 1°C prior to the late 20th century levels. Society predicts that, global warming may be true, and that it is potentially dangerous, but since we just exited a time of modest cooling in terms of temperature, then it’s likely that the Earth will warm up sooner or later. It wouldn’t be strange if we experience another cooling period in the near future.
Personally I agree with this statement, but to say that global warming is nothing to be afraid of, then that’s a whole other problem. I’d say that the people are thinking to far ahead of time, they believe what they want to believe. Instead of having thought about when global warming will stop, we ought to consider the current evolving problems that are already happening. Predictions like those above aren’t always true. Let’s just say, what if global warming kept on continuing with temperatures going up, and that sea levels would actually considerably rise ,the amount of precipitation would actually change for worse ,what can we do about it then? Is this form of self-reassuring going to help out with anything? We aren’t cautious enough to be prepared for those matters. It would always help to be a little cautious. One-day society will feel regretful for being too laid back.
One reason why I see global warming as an alarming matter is because personally I have more or less, experienced it. A few years ago in winter, I used to go to school wrapped in layers and layers of thick clothing ,and not just me ,everyone does. But then just last year or the year before that, winter came again and
This time, at most I only wore a sweater, sometimes it’s even too hot to wear that one heck of a thing on. And the same goes for summer, it’s been getting hotter and Hotter than it usually is. People may counter this by saying “what about the devastating snowstorms and freezing temperature in Europe just last year? How do you explain that? Is the Earth actually getting “hotter”?”-Well, that’s just it. That’s just how bizarre global warming really is: One moment it’s hot and the next, extremely cold. This is because global warming also affects climate change and the amount of precipitation, these effects are more or less related to the problem, though more research is needed to clearly explain why.
People need to be cautious not next year, not the year after that, not even 10 years later, but now! We need to act now! We don’t have to do much, thinking of how to solve it and how to prevent it, that’s the scientists and government’s problem. We more or less, don’t need to care about those matters. What we do need to care about is our daily routines, our lifestyle. It may sound stupid but it’s actually the things that we do everyday that’s causing global warming. Try using paper bags instead of plastic ones ,refrain from using fuel powered machines and vehicles such as cars ,that produce CO2,....start taking those countermeasures now and you’ll never regret it in the future!
