What are the causes of Global Warming?

Question

Man made causes, natural causes and also things on deforestation and the greenhouse effect

Answer 1

I'll simplify the answer a bit to less technical Terms:
1. Over Population Driven Economic Growth Driven Resource Depletion Driven (www.un.org)

2. BOTH Developed-Industrialized nations' pollution (US was No. 1). as well as Developing countries (India & China are No. 1 Target now). (Watch Fox. News)

3. Too many cars, trucks, SUV, racing, and too many selfish, lazy, anti-environment people. (www.nascar.com)

4. Corporations/ Factories/ Companies/ Individuals who only care about their immediately profit/ convenience instead of long-term sustainability and consequences (watch the movie "Corporation)

5. Commercialized Political Party Under Democracy/ Capitalism Society in addition with imperialism military warfare and business at the cost of ignorant and conservative citizens (see US History)

Answer 2

The climate system varies both through natural, "internal" processes as well as in response to variations in external "forcing" from both human and non-human causes, including solar activity, volcanic emissions, and greenhouse gases. Climatologists agree that the earth has warmed recently. The detailed causes of this change remain an active field of research, but the scientific consensus identifies greenhouse gases as the primary cause of the recent warming. This conclusion can be controversial, especially outside the scientific community.

Adding carbon dioxide (CO2) or methane (CH4) to Earth's atmosphere, with no other changes, will make the planet's surface warmer; greenhouse gases create a natural greenhouse effect without which temperatures on Earth would be an estimated 30 °C (54 °F) lower, and the Earth uninhabitable. It is therefore not correct to say that there is a debate between those who "believe in" and "oppose" the theory that adding carbon dioxide or methane to the Earth's atmosphere will, absent any mitigating actions or effects, result in warmer surface temperatures on Earth. Rather, the debate is about what the net effect of the addition of carbon dioxide and methane will be, when allowing for compounding or mitigating factors.

Due to the thermal inertia of the earth's oceans and slow responses of other indirect effects, the Earth's current climate is not in equilibrium with the forcing imposed by increased greenhouse gases. Climate commitment studies indicate that, even if greenhouse gases were stabilized at present day levels, a further warming of perhaps 0.5 °C to 1.0 °C (0.9–1.8 °F) would still occur.

Answer 3

This is a huge and complex subject, and doesn't deserve the brief answer I'm ging to give. And bear in mind that causes are still being investigated and evaluated.

Global warming is generally recognised as being caused by the erosion / destruction of the ozone layer and heat trapping caused predominantly by "greenhouse gases" such as carbon dioxide and methane. The ozone is one of the aspects of the atmosphere which prevents the transmission to the surface of the Earth from the sun of high frequency radiation such as ultra violet light, x-rays and gamma rays which are cumulatively damaging to life - the higher the exposure, the more risk of various cancers and mutations to genetic material which is passed on to the next generation. Take a look at the effects, post war, of the survivors and children of survivors of Hiroshima, Nagasaki and the Chernobyl disaster to get an idea of the possible consequences of exposure.

The main man made cause is generation of carbon dioxide, a gas which traps energy received from the sun. Industrial waste products, huge levels of traffic, household energy consumption and waste disposal are areas which have to be addressed, among others. CFCs used as propellants in spray cans were a large cause for concern in the late 1980s, but have been largely eradicated now.

Deforestation is a contributing factor, because cutting down trees releases the carbon dioxide locked in the plants. Living plants absorb carbon dioxide during respiration (breathing) and, incidentally, expel oxygen. Without plants, we wouldn't have any replenishment of the oxygen we breathe (or food - we eat plants and plant eating animals).

The amount of vulcanism (volcanic activity) is also a factor. A large eruption of the scale of Krakatoa in the 1880s could do untold damage to the atmosphere (as well as spewing out debris which would temporarily occlude the sun and reduce the energy we receive).

Believe it or not, a natural cause for concern - cows farting, and their manure - is apparently a large contributor to greenhouse gases, especially in India, where the cow is a sacred animal.

We do know that there are a huge amount of interconnected phenomenon that result in the Earth being rendered habitable by living organisms, and that we are contributing to a tilt in the natural balance in favour of global warming, but no-one knows how much. We DO need to decrease our contribution, especially in industrialised nations. Because like many systems in equilibrium, as soon as it begins to fall into a chaotic state, the cascade into disorder is very quick indeed, and invariably irreversible.

So much for a brief answer (phew!).

Answer 4

worldwide warming will become worldwide cooling by way of fact once you have invested a great quantity of potential faking, forging, manipulating records and merchandising the fake perception that CO2 motives a international temperature upward push however the suggestion starts off to coach a cooling trend then you certainly pull the previous switcheroo and with a bit of luck desire actual everyone seems to be so innovations broken by employing the genuine pollution, mercury, lead, fluoride and Fox information that their comfortable minds may even settle for that its a threat. the fact is unquestionably grew to become into that there grew to become into no genuine guy-made worldwide warming to start with, and any average warming grew to become into thoroughly organic. worldwide temperature is pushed specifically by employing image voltaic pastime, and image voltaic flare pastime is now at a low so the planet is quite at the instant cooling after an ever so average upward push. So the respond is..... it can't. One does not reason the different the temperature purely fluctuates reckoning on image voltaic pastime.

Answer 5

Mainly the green house effect ie carbon dioxide being released
in the atmosphere.The trouble is, the main polluters like America
are unwilling to cut back in case it destablises the economy.If we carry on as we are, nature has its own way of sorting things as
each year floods and other global disasters are becoming worse.

Answer 6

Destruction of the ozone layer. The ozone layer destructs when we use too much electricity w/c causes the burning of fossil fuels producing greenhouse gasses. Greenhouse grasses destroys the ozone layer thus, we experience global warming. =)

Answer 7

The so-called greenhouse effect.

Answer 8

Humans tampering with the climate by pumping an excess amount of CO2 causing the the sun's rays to trapped on the earth's surface

Answer 9

Man making a living of course plus the farting of the worlds inhabitants

Answer 10

Don't forget nuclear weapons can cause some global warming.
