Is global warming a cycle or man doing?

Question

im doing a kind of a report to start a arguement in my world civs class. so im wandering if i can have your opinions about global warming. So answer this.

Is global warming a natural cycle or a man made effect

Answer 1

You are a sucker if you believe that we are causing global warming. Hell, the Polar Ice Caps on MARS are melting!! Are we causing that too!!!!! Wake up people. This is an international issue designed to force the US to spend and waste money in order to weaken the US economy. No other country will suffer as much as the US if it goes along with this crap. China has tons more people, will eventually out produce the US, and China doesn't have to participate?!? HELLO??? The Smart Scientist (which out number the green-idiots) know that this is a normal cycle. 30 years ago, the same green-idiots were claiming "GLOBAL COOLING". Only a fool would jump whenever these guys say jump. There are too many variables too "predict" the global weather, yet some think they are smart enough when they only use 2 out of 100. And don't you dare say that I am being ignorant. I have done a thorough research on both sides for several months. Did you know CO2 is proven to actually cause an increase in plant growth! Where ever there is plant growth, there is more OXYGEN! Did you know that the Sun goes through cycles! Right now the Sun is in a warming cycle. Maybe that has something to do with MARS?!? Hmmm, and it was in a cooling cycle around the time people where running around and saying the earth was cooling! Sorry to disapoint you, but the more people learn the truth, the better off we all are. You all need to focus on something that floats, not something that sinks!!!!

Answer 2

Conner may be a major in something but to suggest nothing like this has ever happened in history is silly. We have been warming since the last glaciation for at least 6000 years. There have been some ups and downs since then. There was a time in the middle ages that were warmer than now. There was a time from 1940 to 1970s that was cooler. CO2 is a lagging indicator with temperature meaning that the CO2 probably didn't cause the temperature increases, rather the temperature increases caused most of the CO2 increased concentrations. At the most, humans may have contributed about 50 parts per million in the CO2 concentrations. There are currently almost 400 parts per million. It is possible that man contribution to CO2 has increased the temperatures slightly. It becomes difficult to quantify the actual benefits and costs. Clearly, the alarmist focus only on the bad and ignore any benefits and exaggerate man's contribution. There is an other much more important greenhouse, water vapor. Since water vapor cannot be blamed on man (at least in a credible way), it is virtually ignored. The models predicting global warming clearly are manipulated by the modelers to get the result they want. If they don't predict problems, then there is no need for further research and thus you have a system that is prejudiced for predicting gloom and doom and that is hardly a way to make educated solutions.

Answer 3

The biggest contributing factor in global warming is the sun. CO2 has no effect at all. This is all media hype and global hysteria. It's a smoke screen to real problems that should be addressed.
If we want to be "green" then forget the CO2 and concentrate on reducing pollution that kills us and makes us all ill. Preserve your environment, stop killing the forests and oceans, focus on deadly and poisonous substances that industries are dumping into your water and air you breath.
CO2 is not a problem. If you think it is then stop breathing. That way you will stop the global warming. :o)
So the answer would be: It's a cycle. The cycles are long and short and some global weather changes can not be even called a cycle as they are short trends lasting 2 to 5 years.
The one we are in now is more of the cycle is a government and media cycle called "let's create hype and get some more money" Trust me.

Answer 4

Global Warming is a cycle and a read through a History book will prove that. The Earth, like everything else in the universe, evolves and this causes weather changes. Humans have very little impact on the output of carbon (it is not even a pollutant) as volcanoes, the sun and other natural phenomenon have much more effect on the changing weather patterns. A good example of this is that while we are warming up, so are the rest of the planets in the solar system and last I checked humans weren't living on Venus, Mars and Pluto...

Answer 5

Mankind is responsible for about 5.7% of the total emissions. Most of the causes are forrest fires, volcanoes, and natural evaporation of water which is humidity or clouds - so man is not the cause of global warming. Over millions of years, global warming and global cooling cycles have been documented as a result of variation in the Sun's radiation (look up Maunder Minimum), variation in the Earth's orbit around the Sun (it is sometimes circular and sometimes elliptical), and variation in the tilt of the Earth's axis between 21-23 degrees (the Earth wobbles a bit!).

If the Earth is warming a bit (.7degrees C), there is also evidence that global warming is taking place on Mars at the same time!!!!! I am not aware of any "humans and SUVs on Mars yet).

Answer 6

It is not man-made pollution. Its the cycle of how global warming rise and fall naturally. Billions of years ago, global warming was there, and the Earth was totally too hot to survive (that's when the birth of Solar System came). Earth had a very high carbon dioxide and a very little oxygen. Somehow, Earth evolves into oxygen planet, and sprang lifeforms that favors the humanity. Global warming was born. Global warming have heated this planet for years and years and years, thus there is no way to reduce it. What caused the global warming is because the sun radiation has reached the Earth, thus warming the planet up naturally. When the global warming at its peak, Ice Age begins (that's when all dinosaurs dies because of the drop of global warming). The Great Ice Age have been there for tens of thousands of years. After the Great Ice Age ends, global warming begins to rise again. The next Ice Age won't begin for a long time, thus we have polluted this planet, BUT not all pollution creates or helped global warming to get hotter. One day, Global Warming will fall and returns to the Ice Age.

Answer 7

Global warming is the natural worlds response to variance in atmosphereic composition, orbital dynamics, and solar output. Many factors contribute to the long-term climate of the Earth.

Among those factors is the human contribution of gasses to the atmosphere that block the transmission of infrared radiation from the surface into space. This contributes to the overall energy balance.

"Balance" is an important word here. Without any greenhouse gasses, the Earth would be very cold. With too much, the Earth is too hot.

Life on Earth is optimized for current conditions -- no matter if evolution of God made life that way. Change the conditions, and life suffers.

Answer 8

Consider that about 1,000 years ago or so, grapes were a primary cash crop in England and Greenland was actually green and could support crops. Since then these same environments have cooled considerably and now appear to be warming again. That alone should make people skeptical about man's use of fossil fuels being the cause of global warming. After all, there wasn't enough use of those same fuels 1,000 plus years ago to have warmed to planet to that level back then.

Answer 9

The first man induced effect was the early Norse in Greenland who cut down the forest and over cultivated the soil in Greenland. There that said where is the man made effect in the "little" Ice Age or Global warming before the advent of major hydrocarbon based industry?

Answer 10

Oh this is absolutely mand made. Mankind is responsible for everything that ever happened on this earth. Every change in climate is our fault. Warm weather... our fault! Cold weather... our fault! We created the ice age beacuse we couldn't get global warming up to speed yet!

Come on people. Use some common sense, and quit listening to Al Gore. This is the same used car salesman that tried to convince you that he invented the internet.

Should we take better care of our environment? Yes. Should we reduce pollution? Yes. Should we be better at conserving? Yes. Are we creating a life threatening global warming? NO!!!
