Is Global warming by the human race real or is the earth going through a natural cycle?

Answer 1

It is the speed of the warming that is alarming.Next time do a little research.

Answer 2

Global warming is real. It is caused by carbon dioxide releases. Human carbon dioxide releases are far greater than all natural sources combined (about 40 times larger than volcanoes). Human carbon dioxide releases are primarily due to burning fossil fuels. That in a nutshell is the reality.

There is nothing natural about it.

To learn more a very good place to start is the wikipedia global warming article. It is very well referenced and offers many links to other sites with more detailed information.

The best introduction a non-technical person can get is the movie "An Inconvenient Truth". It is the most accessible description of the science available and within 2 hours you will have a grasp of the very complex subject.

Answer 3

In reality, a large part of the global warming is contributed by the volcano explosions throughout the planet. Those explosions release huge amount of carbon dioxide into the atmosphere that account for the green house effect that causes global warming. Yes, humans also contribute to this problem by our emissions. But that only exacebates the problem and is definitely not the major cause of it.

Answer 4

Yes and Yes.

The geological record of the earth's temperature is very clear - for millions of years the earth has been going through cycles of warming and cooling. The Earth has been warming up since the end of the Pleistocene (about 10,000 years ago) due to complex influences that we don't completely understand, but they include the angle of the earth's rotational axis to the sun, the average distance to the sun, reflectance of the earth's surface, and atmospheric conditions including CO2 and dust.

Even if there were no humans on Earth with all the CO2 and pollution we are creating were removed, the earth would gradually become warmer without any human influence. Eventually, for reasons we don't understand, the Earth would then begin a cooling cycle again - the period of each cycle is irregular but they seem to last about 100,000 years.

So the best we can hope for is to help slow the RATE of global warming. I think the evidence is undeniable - the rate of global warming is unprecedented, due to the impact of 6 billion people in a very industrial society.

One of the contributors (and certainly the one we humans are responsible for) is the amount of C02 in the atmoshere. Fortunately, the Earth has a natural buffer that keeps CO2 levels in check - vegetation. As the CO2 levels increase, chloropyll-based green plants increase their rate of photosynthesis which converts CO2 to to O2. Also, forest fires have been a significant source of CO2 in the atmosphere for thousands of years. As CO2 levels increase and 02 levels decrease, forest fires will not burn as efficiently, meaning that nature already has ways of keeping atmospheric CO2 and O2 levels in balance.

But our consumption of fossil fuels (coal, oil, and gas) and even wood and peat, means that we are producing CO2 faster than nature can recover. On top of that, everything humans do creates heat and that needs to be dissipated in the earth's atmosphere.

Many people would say we should reduce our energy consumption, and that's true, but nobody seems to be doing anything about it. With the technology we have today, probably the single most reasonable thing we can do to help slow the rate of global warming is to replace all of our fossil fuel-powered electrical generating plants with nuclear plants.

The biggest opposition to nuclear plants seems to be the question of radioactive waste. Now here's a fact: a coal fired power plant (most of the world's electricity is produced from coal, esp China, Australia, and USA) produces more radiation than a nuclear power plant.

Of course the only way to completely eliminate our impact on the Earth's temperature is stop using all forms of energy, as every one of them creates heat and other side effects.

Answer 5

Climate through geologic time has entered in ice ages, and warming ages, a periodic cycle, that goes on and on through geologic time.....
We were supposedly entering a cooling trend, when suddenly it was discovered by scientists that earth's warming up due to greenhouse gasses. Politicians, and people who just refuse to believe global warming is really happening, use this argument to evade reality saying that it is a natural cycle of earth.
But you know what, ecosystems, for example, coral reefs, have a very sensible temperature thresholds, and as temperature rises, these remain almost unprotected to warmer ocean temperatures. Coral reefs have suffered a lot these last two decades, with massive die offs and bleachings in the Caribbean and Australia.... all due to global warming. So it is quite difficult for us to ignore Global Warming, even though it is sometimes difficult to pin point the temperature trends compared to past times.... Remember, animals, or even people can die with a bag of plastic on the head in just minutes.... so, that can happen with temperature to coral reefs..... just as an example.
So at least to me, it is clear that we are in a real rat race, maybe difficult to detect in graphs, but nature is warning us something is not right....., not to mention the rise in ocean level and the consequences this might provoke, to animals, plants, and the use of land.....

Answer 6

human race

Answer 7

the human race has not helped but keep trying the world will always change ,we just make it faster
