Is global warming caused by humans and their activities?

Humans are a major contributor to global warming, many of our actions from producing raw materials such as steel and electricity, manufacturing road vehicles, ships and aircraft, fridges, televisions (this list is endless) to transporting goods and people around the world, encouraging cows to produce milk (by product methane) and even incinerating our waste, all have a detrimental effect on our world A: Although global warming may be caused by human's greenhouse gasses, there is surprisingly little evidence for this Firstly, humans emit surprisingly few greenhouse gasses compared to the rest of the Earth. Most of the greenhouse gasses (something like 60-70%) come out of the oceans. A lot (like 30%) comes from things on land breathing.

Very little (around 3%) comes from human pollutants (such as factories) Secondly, there is not much evidence that CO2 is the cause of global warming. Although both CO2 and global temperatures are both rising now, this has never happened before in the Earth's history. Most of the time, it's just the opposite, when CO2 is up, temperature is down Lastly, global warming is happening on other planets, so the Sun as a cause is a very serious contender.

Mars' ice caps are melting and Jupiter is having storms even more violent than usual A: It is the solar radiation that is ABSORBED by the earth that is, supposedly, a problem. This absorbed sunlight is later re-emitted in the form of infrared radiation. Carbon dioxide and other so-called "greenhouse gasses" (the most important of which, by far, is water vapor, by the way) in the atmosphere then absorb this re-emitted (not reflected) infrared radiation, causing the atmosphere to warm.

This is the greenhouse effect, and it was happening for billions of years before the first internal combustion engine was invented, and without it, the Earth would be far too cold for humans to have evolved. The theory of anthropogenic global warming has it that EXCESS CO2, from the burning of fossil fuels, has created an "enhanced" greenhouse effect, causing the atmosphere to warm well above some "optimal" temperature, whatever that might be - no one seems to be able to state what the optimal temperature is. (But this theory is wrong, because CO2 absorbs only a small range of wavelengths of infrared, about 10-15% of all IR radiation, and even in that small range, it has to COMPETE with water vapor to absorb the IR.So, as it turns out, between the water vapor and the CO2 that was already in the atmosphere long before the industrial revolution, all of the available IR radiation was already being absorbed.

So, it doesn't matter how much CO2 is in the atmosphere - there's only so much IR that is going to be absorbed by CO2, and we were at that level of IR absor p tion long before the industrial revolution. ) Also, what you call "pollution" is, in fact, carbon dioxide. Without CO2, there would be no greenhouse effect, nor any human life on Earth.

CO2 is a vital nutrient to all plants. Since when did we start calling a substance that is so clearly and vitally important to life, a "pollutant"? True, we might have more than we NEED at the moment, but the trees certainly aren't complaining.

They're lovin' it A: This really is the disputed issue. It is very clear from the geological evidence that periods of global warming and ice ages do occur. What is perhaps less clear is whether or not industrialization and other human activities are accelerating the earth's natural processes.

Evidence linking carbon dioxide to periods of warming do suggest that our appetite for fossil fuels is adding to the already present natural processes A: There is no disagreement among accredited climate scientists that global climate change is caused by human activity A: While there are clearly more alarmists than skeptics in the climatological fields, there are many "accredited" climate scientists that dispute the theory of anthropogenic global warming. Richard Lindzen, Timothy Ball, Robert Balling, Roy Spencer, Bill Gray, Marcel Leroux, Fred Singer, Reid Bryson, and William Kininmonth are a few of the more famous ones. Others, like David Legates, George Kukla, Tim Patterson, John Christy, and William Cotton, while acknowledging the possibility that human activity influences climate change, either say human influence is minor compared to the natural forces causing temperatures to increase, or insist that we do not know enough about the climate to say, with certainty, that mankind is causing warming.

And there are dozens of prominent scientists in other fields related to the issue that have weighed in on the skeptic side of the issue A: Any and all humans who do anything that releases carbon dioxide into the air by burning anything is responsible for the greenhouse effect that is causing global climate change A: Firstly, humans emit surprisingly few greenhouse gasses compared to the rest of the Earth. Most of the greenhouse gasses (something like 60-70%) come out of the oceans. A lot (like 30%) comes from things on land breathing.

Very little (around 3%) comes from human pollutants (such as factories) Secondly, there is not much empirical evidence that CO2 is the cause of global warming. Though CO2 and temperature do appear to be strongly correlated over at least the last half-million years, it has always been temperatures going up first, followed (hundreds of years later) by CO2.So, if there is a cause-and-effect relationship at all between the two, clearly, increases in temperature cause increases in CO2, not the other way around, as global warming alarmists claim Lastly, global warming is happening on other planets, so the Sun as a cause is a very serious contender. Mars' ice caps are melting and Jupiter is having storms even more violent than usual.

Also blame the sientest who created the greenhouses they are known as haters of nature. :( Yes! There is some debate over whether global warming was started naturally, and it might have been, but humans have made it worse and worse.

For example, the more carbon dioxide in our aptmosphere, the higher the temperature, causing global warming. And, of course, humans are the ones producing all the carbon dioxide by using cars, etc A: This is a tentative topic, and many scientists disagree on it. Some say that we are amidst a natural warming and cooling process of the Earth, and others say that the green-house gases we are releasing are causing the sudden warming.

We have undoubtedly sped up the process by our actions, and there is more supporting evidence and data that suggests that humans are a main cause of global warming A: No real science group claims that global warming is a completely man induced event. They do claim that man contributes, and there is much evidence that this is possible. The amount that man contributes is very debatable A: The primary cause of global warming is man's burning of fossil fuels (coal, oil and natural gas) in industry, transport and to generate electricity.

All these human processes release.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
