Is global warming definitely caused by humans or is it a natural event that has happened before?

Global warming has happened before but it happened over many thousands of years. The present global warming is happening extremely fast (200 years) and is definitely being caused by human activity. We can measure the cause, the carbon dioxide in the atmosphere, and we can test to prove it comes from fossil fuels (coal, oil and natural gas).

Why change global warming when it is a natural process?
We certainly should not change the natural processes of global warming. It is well known that greenhouse gases, at about the right concentrations, keep the world at a comfortable temperature suitable for human existence. But by adding new greenhouse gases, such as carbon dioxide produced by burning fossil fuels (coal, oil and natural gas), we are changing that natural process. We need to stop interfering with nature and reduce our production of greenhouse gases before the recent rises in average global temperature cause irreversible damage.
How earth climate has change over time?
Climates changing randomly. scientific tests have proved that global warming and cooling have happened periodicly since the time of the dinosaurs and way before pollution existed...
How can you prevent global warming from affecting animals?
You can't. Global warming is a natural, cyclic event that has happened before, and animal life survived. The planet is actually going through a cooling term now.A:Animals whose habitats are seriously affected by global warming have to adapt, move or die. It will be difficult to stop global warming as we have left it so late, and our interventions are well below what nations have promised. It will not be possible to save many animals.
Is Earth obsolete?
Far from it. It may be more accurate to say that we are obsolete. The earth has a few more cycles to go, possibly without us! All of this global warming talk is very, very real. But it isn't much more than a yawn for earth. For us, it is possibly the end. These warming and cooling cycles have taken place on earth many times before. We are very likely speeding up the earth's natural processes, but they are natural processes for earth nonetheless.
How does global warming affect society?
Global warming affects society both because we must adjust to it, to the extent that it is now unstoppable, and because we must change our use of fossil fuels in order to minimise further global warming before catastrophic climate changes occur.
Why do some scientists think climate change is natural?
because it's happened before with the ice age so some say it's natural for the climate to change as we have evidence that it has done in the past. a more valid explanation is that we are producing more greenhouse gases and that sun is expanding, causing global warming.
Is global warming happened before on earth?
Yes, Planet Earth has undergone several natural fluctuations in terms of global mean temperature (warming and cooling) over the past millions of years. BUT never before has the Earth shown a variation in temperature as seen in the past few decades. Human driven emissions coupled with our exponential growth are the driving forces for this unnatural change of our global temperature.
How do you write an essay on natural global warming?
Write sentences the way you speak - just pretend you are telling this to a friend, and write down what you would say. What would you tell them about this topic? Look up some facts about global warming! How will you explain these facts to your friend? What is the difference between natural and pollution-caused global warming? If you just start writing, you will be through with your assignment before you know it!
What started climate change?
Climate change is a natural phenomenon. It has happened many times in earths past and will continue to do so.A:Climate change is the result of the global warming that has been happening, especially in the last forty years, when the earth has warmed more quickly than it has ever warmed before. Global warming is being caused by deforestation and the burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide (CO2).
Is global warming natural?
There is a natural warming of the earth caused by the normal greenhouse effect. This has been keeping the earth warm enough for live for millions of years.The global warming that has been occurring since the beginning of the Industrial Revolution (1750) is believed to be caused by human activity, and so is not natural. We have cut down forests that before removed carbon dioxide from the atmosphere, and we have burnt fossil fuel in vast amounts, releasing additional carbon dioxide into the atmosphere.
What caused global warming before humans were around to take the blame?
Global warming is natural. This is characterized by the increase of temperature on a certain planet. Basically, it is the sun which heats up this planet. The heat is screened through greenhouse gases whenever they get out.
Is Global Warming a cycle?
No, it is not a cycle. Natural warmings and coolings happen over thousands of years. The earth has never warmed up so quickly before.
Is space nature?
Space is most definitely natural. It has existed for literally billions of years before not only human beings but life in general.
Is there any role for saving water to prevent global warming?
No. Saving water usually will have no effect on global warming.Global warming is changing the climate. This will mean that some places will have less rain than usual. This happened anyway, even before global warming began. So saving water, that is, using less of it, will mean that there will be spare water in the dams, that will last longer.In some places, water is supplied from a desalination plant, turning salt water into fresh. This process uses a lot of energy, which may be produced by burning fossil fuels (coal, oil and natural gas). If this is the case, then saving water will help to slow global warming.
What was invented first fire or the wheel?
Fire is a natural phenomenon and thus it was not invented. on the other hand, fire was definitely discovered by man before the wheel was invented.
Why did the world deal with ozone depletion before global warming?
The world deals with ozone depletion before global warming. It is because ozone depletion is much fatal.
How does electricity contribute to major problems such as pollution and global warming?
Most electricity is generated by the burning of fossil fuels (coal, oil and natural gas). This releases carbon dioxide, causing global warming as well as sulphur and nitrous oxides which pollute the atmosphere before turning into acid rain.
