Are Humans reponsible for global climate change or is it part of Earth's 4.5 billion year old cycle?

Answer 1

Have no fear... before long, humans will likely kill themselves off, and then the world will quickly return to it's pre-modern-human state.

Answer 2

Yes, Humans are responsible for global climate change, through the smoke from automotives and factories and the pollution caused from the detonation of nuclear weapons going into the atmosphere and this in turn destroys the protective coating of the atmosphere that blocks the intense heat of the sun, which leads to the sun's rays penetrating more intensely upon the surface of the Earth causing record-breaking heat and wild forest fires and many people die from dehyrdration. The current effects of global warming are just the beginning, but at least we are able to still manage our own existance, but things will get much worst if we don't stop man-made pollution as soon as possible, or else there will come a summer in which the heat will be too intense for humans and other living things to tolerate and there will be much worst fires than those that have already come about in past summers.

Answer 3

Humans are responsible for the abnormal warming of the past 100 years or so. Had humans not been pumping out more CO2 than all natural sources combined for more than 100 years and had humans not been cutting down much of the worlds trees, the earth would not have heated up as it has in that time. Natural climate change does not take place as fast as this event has.

Answer 4

Were it not for all the other factors-ozone layer being destroyed completely in some areas while weakened in others, acid rain, air quality being polluted and so on you could possibly believe its a naturally occurring cycle but all the other conditions were not present because they are man-caused and global warming is accelerating at a much,much faster rate than thought possible.I doubt there were red alert days because the air was so fouled back then. Am sad to say its our doing because no one really card enough.

Answer 5

If it is not a cycle, it must be humans- at least that is what society attributes. If it is human caused, two of the main sources point to carbon based chemicals or methane in the atmosphere. My solution- (1) no more burning= get rid of fire. Since the biggest source of methane is cow flatulence (humans contribute as well) Get rid of the cows and support vegan-ism. Never mind- bean curd burgers give people gas= more methane. Okay, no Fires and no Farting to save mother earth and Her so called "hot flashes".

Down with the F and F!

Answer 6

Are we as Americans always to blame when there is pollution, greenhouse gases, etc? Please realize that we are a country of 300 million people. India and China both have well over a BILLION each. Oh, right...they are a backwards lot and don't know how to damage the earth. China right now is using more oil than it ever has in it's history.

Also, consider natural pollutants that can cause atmospheric havoc. Volcanoes, naturally occuring forest fires, tornadic storms, hurricanes...the list goes on.

So give me a break...next volcano that decides to explode, we'll have Al Gore plug it with his family's SUVs and his private jet.

Answer 7

oremus_fratres: take your non secular ideals to the non secular section. We communicate with regard to the actual international in right here. the single that's 4 and a a million/2 billion years old, shown by ability of various self sustaining dating techniques, NONE of which contain carbon dating. And yeah, your faith did not build the pc you're answering on. technology did. A planet like the earth might desire to not have shaped in the present day after the super bang. After the super bang, we had hydrogen and helium, yet hardly no heavier components. the 1st stars shaped, and that they have got been in a position to fuse components as much as carbon, yet not something heavier than carbon, which contain oxygen, existed yet. ultimately, while the 1st stars had lived their lives and died out, they died in super supernova explosions which had adequate power to fuse the heavy components. Now those heavy components are drifting off via area as a cloud, and at last the gravity between the little debris makes them condense right into a clean cloud and kind a clean megastar with new planets, and in user-friendly terms now do the heavier components exist interior the formation of that new planet to make a place like earth. This technique takes a protracted time. Ohh, say, approximately 10 billion years :P specific makes you think of approximately how stupid we are to think of we are specific and the universe is right here for us, does not it? cutting-edge human beings have existed for some thing like 2 hundred,000 years. that's approximately 0.00000014% of the age of the universe. Heck, this is in user-friendly terms 0.00000044% of the age of the earth. we are the hot adult males on the block no count the kind you seem at it.

Answer 8

Definitely humans! If the entire human race will be erased from the earth, this world will be a better place to live in. The earth, with all the flora and fauna, will survive WITHOUT MAN.
Nature needs nothing from man.
Nature owes nothing from man.
Man is the problem. However, only man is the solution.

Answer 9

Not one person alive knows the answer to that question but I believe it is part of the 4.5 billion year cycle

Answer 10

We have merely reduced the 4.5 billion year cycle to 4.4499995.

We experience the massive acceleration so dramatically because we are here for such a brief moment, in comparison to this cycle.

Answer 11

It's most definatly part of Earth's cycle, there is a lot of evidence to support this as Global Warming doesn't have evidence, just beliefs.
