global warming happening?

Question

Is it true that global warming is happening

Answer 1

Don't shut down just because I'm saying this. Please keep reading. There is no need to worry about global warming. I seem to be in the minority with this belief, but have evidence to back my view. The earth’s main source of energy is the sun. The sun shines on the earth, giving the earth energy to warm the planet, but light just bounces off the earth and radiates into space. This cools the planet. If that were the end, the earth would be a freezing wasteland. But there are certain gasses (greenhouse gasses) that trap the light from the sun. The gasses are principally water vapor, methane, and carbon dioxide. Now this is what worries most scientists. Since the industrial revolution, we have been putting a lot more carbon dioxide into the air. Also, the population of the earth is greater than it has ever been, so more people breathe out carbon dioxide. Between these two factors, there is a lot more carbon dioxide in the air than there used to be. As a result, there is a lot more carbon dioxide that can trap a lot more light that would otherwise radiate into space. This causes global warming, right? Well, not exactly. Please keep reading and let me explain why. Studies prove that carbon dioxide amounts produced by human activity, are only 3% of the natural processes on the earth. That is not a significant amount. Also, when humans burn fossil fuels, many other gasses are released besides carbon dioxide. Some of these gasses reflect light instead of absorbing it. This actually cools the planet. So any human produced carbon dioxide is “cancelled out” by the cooling effect of other gasses.
Please keep reading. I have one more point to make. The hole in the ozone layer is thought by some to be linked to global warming. This is not true, as you will hopefully see soon. Ultraviolet light has so much energy that it kills living tissue. Cells that are exposed to it die at a high rate. Ozone is a gas that is made up of three oxygen atoms, forming a filter. It filters ultraviolet light so it does not kill everything on the planet. As you can see, it is a big problem to have a hole where ultraviolet light gets through. So let me tell about the ozone hole.
On October 8, 1993, scientists discovered a “hole” in the ozone layer. It was greatly disturbing, and much research and money was poured into it. The scientists discovered that, under certain conditions, chlorine atoms break down ozone into oxygen. They found these chlorine atoms in the ozone layer above Antarctica. Many sources put chlorine into the atmosphere; one source got a lot of attention: Chlorofluorocarbons, or CFCs. CFCs are incredibly useful in these ways: they are used as medical sterilizers, for refrigeration, and used to efficiently put out fires. Plus they are non-toxic! Well, now they are banned. We can still use them, but cannot make them anymore. Eventually the supplies will run out. You might be asking, how do CFCs get into the ozone layer? Well, in August, a weather phenomenon in Antarctica occurs. It is called the Polar Vortex. Winds steadily blow upwards, and temperatures can reach as low as –130 degrees Fahrenheit. Chlorine containing ice particles get blown up into the ozone layer, and the chlorine can then destroy the ozone layer. By November, the Polar Vortex is gone.
So in the end, the ozone hole is a seasonal phenomenon that happens four months out of the year. Also, how many people live in Antarctica? Hardly any do. So the CFC ban will reduce the depth of the ozone whole (it won’t completely eliminate it because it was there before CFCs were used) for four months were hardly any people live. The ban won’t save lives; it will actually result in death. Think about it. Third world countries will not receive food due to lack of efficient refrigeration. Fires will last longer and be larger without the CFCs to put it out quickly. Infections will increase due to inefficient medical sterilizers. Use the cost/benefit analysis, and you will see that a CFC ban is a bad decision.
I do not believe that the ozone hole is related to global warming because of this: there are two layers in the atmosphere: the homosphere and the heterosphere. In the homosphere, there are (from bottom to top) the troposphere, stratosphere, and mesosphere. In the troposphere, the temperature decreases with increasing altitude. But in the stratosphere, the temperature increases with increasing altitude. Once you get into the mesosphere the temperature decreases with increasing altitude again. Why does the temperature increase with increasing altitude though? It is because that is where the ozone layer is located. As you know, ozone molecules filter the heat, causing them to heat up. This increases the temperature of the ozone layer, and therefore the stratosphere. Now, if there was a decrease in ozone, I would think that there would be less ozone to filter ultraviolet light, and therefore less heat being transferred to the ozone layer. So, as you can see, a decrease in ozone would result in a cooling effect rather than heating. It is absurd to believe that the ozone hole has to do with global warming.
If you have seen charts illustrating the rise in temperature over the last few years, look at the range of temperature change, and don’t be fooled by the drastic change. Some graphs show lines that look like huge changes, but the temperature change is so small it is written in decimal numbers. I would recommend the book How To Lie with Statistics by Darrel Huff.
I hope that whoever reads thins will learn something, and realize that global warming is not a problem.

Answer 2

Of course it's happening I mean look at how strange the weather has been. Here in Georgia it's wintertime but it's been like in the 60's-70's which isn't winter weather. The globe warming is getting worse everyday.

Answer 3

Yes, from all the pollution that we have created, from are cars. Millions of cars on the rode each day, and all that heat generated from exhaust fumes, then the heat in the atmosphere, melts more of the ice from the poles, then it brings more water, the sun soaks it up, but then it rains that much harder, causing floods, and places start to get warmer were it usually isn't suppose to be, and places get colder were its not to be also, this brings on volcanic reactions, with gives us earthquakes, which causes the earth to slightly tilt on its axis, throwing the position of the sun off. which gives you this vast warming on the globe, more than it should be.

Answer 4

Yes, it is true that Global Warming is taking place even at this very moment.

Answer 5

Definitely. Carbon Dioxide from vehicle emissions, pollution etc. can trap heat onto the earths surface. If these actions continue, the Earth will continue to get warmer and eventually cause numerous problems in time.

Answer 6

yes, but it is a natural cycle the earth goes through, people look at things in that happens in their lifetime. we are to for an ice age which is usuallt preceded by a period of warmer than average temps, which in turn keeps more moisture in the atmosphere, more clouds, less sum , more precip, gradual ice age. But one thing I have learned about weather is that it is umpredictable.

Answer 7

A better name would be
Global weather WEIRDNESS

Melbourne (Australia) ;
WARMEST NIGHT 27DEGS e v e r
COLDEST XMAS 12degs e v e r

IN THE SAME WEEK !!?

Answer 8

Yes, it's true the Global warning is talking place........

Answer 9

of course ıt is happenin.we are in december now.and ı am from turkey,but it si hardly raining.ın december!ıt is wery strange u know?ı mean,the weather was used to be better.before even two months ıt would snow.but now?..

Answer 10

yes its 100% true... it was started long tym before... n u r realising now???
