Is Global warming happening because of us or is it a natural cycle the earth goes through??

Question

k so im wundering wat u gys think...personally i think its a natural cycle

Answer 1

In the past it's always been natural cycles - the Earth and the Sun go through many (search for 'Milkkovitch Cycles' and 'Solar Variation' if require more info). These cycles occur over very long periods of time, the shortest one that has any noticable effect on climate takes 23,000 years,

CO2 levels are the highest since humans populated the planet, temps are rising much faster than anything that has ever beore been known - we can analyse the historical climate and have a record going back over half a billion years.

No natural cycle or combination of them could possible cause temps to change so fast and never has done in the past. Temps rising many times quicker than the fastest natural rate.

------------------

Someone always mentions warming on Mars but Mars is just 1 of 172 planets and moons in our solar system, no warming has been observed on 167 of them. Warming is local to individual planets and moons caused by unique events, not caused by the sun - if it were all planets and moons would be warming.

Answer 2

Perhaps I can answer this question from a scientists point of view using the facts from both sides of the argument to meet in the middle. Global warming, by and large, is a natural event. In 60,000 years of looking at ice core samples, I have seen massive fluctuations between heat and cold including three ice ages. However! I have seen the amount of carbon simply explode since 1958 and have the data to back it up. If I were to draw two lines on a chart, one showing the amount of carbon and one showing an increase in temperature, there will be a parallell between them. And THAT is unprecedented! In other words, in 60,000 years, I have NEVER seen such a rise in world wide temperatures as I have in the past 39 years. So with the numbers in front of me, I have to conclude that, although we aren't responsible for global warming, we have definitely exascerbated it beyond any argument. And the answer doesn't lie in government. It lies in us - in what we drive, in what we use for power, and in what we recycle personally. Please consider both sides of the argument before either side claims that there answer is the only answer - that global warming is natural occuring or man made. The Year Without a Summer was brought on by the aftermath of a volcanic eruption in which sulfer was ejected in mass quanitites sending solar radiation back into space. And THAT is part of a natural cycle.

Answer 3

This is a tough one to answer and i guess it all depends on you who talk to as to what answer you're going to get. Man and his ego will always think it's him casuing the change.

But, we know for a fact the poler ice caps on mars are melting and some of the same things happen on this planet are happing there as well. Plato is getting warmer even tho it's getting futher away from the sun.

So maybe this is just a cylce the earth is goig through.

that being said anything one can do to get down on it, .ike driving under the speed limit or car pooling or any of 1,000 things you can do to help with the enviorment is alwasy a good thing. What really funds Terror? Oil!!! The less we use the better

I could go on and list all the things we are doing. One person sanswer on here already says more the enuff on the subject.

If you've heard of Coast to Coast am the did a great show on this that aired sat may 19th. THey also talked about way the bees seem to have gone missing
check it out it's really interesting

Answer 4

It is true the earths climate does go through hot and cold periods naturally, such as an ice age. The reason that we are causing it is because of our emissions, and just the general way we treat our planet. The proof is simple, if you look at a graph of the CO2 emissions, and the temperature, they are in stride with each other. In the last 125 years they have both spiked nearly off the chart, the only answer is sadly us. It seems like common sense to me, when you mistreat something, in this case our earth, things will happen. As for the what is happening due to us, well to name a few, mass extinctions, global warming, bad air quality, etc.

Answer 5

considering we havent seen weather or changes like this in over 150 years i would not say it is a cyclical earth change. even if it is a cyclical earth change do humans want to end up like the dinosaurs? we as humans have a duty to become the most efficient we can possibly be and right now we arent. suburban developments, 4 cars in every driveway. tons of manufacturing and pulluting powerplants and even slashing down hundreds of thousands of acres of trees per day is not helping the cause and is in fact making things thousands of times worse. Increasing our everday efficiency and the efficiency of all buisinesses in america will save us all money, but also have profound impact on the environment and spur new environmentally concious industries. Acting on on pollution is win win. and yes definately it is not a natural cycle. I am willing to change my everyday habits, even buy a hybrid or energy saving car because as an american and socially responsible citizen i owe it to myself and others to seek out the most efficient materials, cars, and appliances so that i can do my part to conserve energy and help pollution levels.

Answer 6

global warming is a manmade cause.the pollution created by humans cause harm to the environment. pollution caused by carbon di oxide has resuluted in the ozone layer depletion. ppl cut down trees.so this increases the amount of carbon di oxide.carbon di oxide has the capacity to trap heat. and so we have ozone layer depletion.if u say that it is the natural cycle that the earth goes through then u r wrong my dear . if earth goes through this kind of cycle then by now the earth would have been destroyed.

Answer 7

It is both - because of us and because of the natural cycle. I think the important question is - whether our contribution can make things go out of hand?

It seems reasonable to think that - considering how much energy we are releasing - we are a big factor. Think of how the sky gets lit up because of our tiny little bulbs. Billions of little engines burning gas and leaking heat seems like it would impact things on a global scale. Why would it not?

Answer 8

The majority of it is due to the lack of respect that we have shown for our planet, but every bit of conservation and awareness make things better.

However, the dinosaurs were wiped out at one point in time and perhaps humans are nearing their time? In that case, I must admit that as a bit of irony, the human's faultiness is predestined and in timing with the natural cycle of things.

Answer 9

the funny thing is that alot of people claim greenhouse gasses such as CO2 are causing global warming but the truth is that the main producer of CO2 is in fact our ocean. When the tempature rises, the oceans release more CO2 which in turn, causes CO2 levels to rise. What alot of these alarmist fail to mention is that the temperature rising is causing the CO2 levels to rise, not vice-versa as many people may believe.

Answer 10

So-called global warming, if it is happening, is basically caused by solar flare cycles. Furthermore, if we limit CO2, then what wil the plants breathe? Plant life uses CO2 just like we use oxygen.
