Do you think Global Warming is occuring from Man , do you Think it is Natural, or both?

Question

List some facts why you think it is man made, natural, and/or both

Answer 1

The Earth's climate is caused by ocean currents in the Pacific ocean.  These currents are known as El Nina/La Nino.

Man has nothing to do with these ocean currents.  Warming is all natural.

Answer 2

of course it caused by man

Answer 3

It's all natural. The earth has gone through several climate changes in it's history. None of them were man made.

Answer 4

neather.is man warming mars so it gets hot.does global warming making winter colder.

Answer 5

Mostly nature

Man contributes an insignificant amount

Answer 6

Mother Nature will take care of us all.

Answer 7

Global warming is very definitely a both situation.

Once the earth warms up, whether by natural or man made causes, we get a compounding effect. Higher temperatures of air also trigger global warming. Warmer air itself causes reduced cloud cover so less cloud cover gives us less reflection and more solar gain. But the warmer air also means we have more water vapor in the  air, and water vapor is our most significant GHG.

So, when we add even a bit of extra GHG so that we raise our temperature, added on top of natural global warming, we speed up our global warming, we make the ultimate temperature higher.

But this does not mean that we can stop global warming. Once the higher water vapor is present, earth will continue to warm up even with no further addition of CO2 or methane.

What we can do is stop our own component so that eventually we might see our limiting temperature no higher than it was in earlier cycles. We know life has survived earlier cycles without our additional CO2.

Attempts to describe percentage of fault are meaningless and necessarily wrong. As temperature rises, the contribution that we are making becomes progressively less, and the contribution we have already made becomes larger. We can take no responsibility for the contribution we have already made until we have a means to undo the contributions of the past.

Warming of the earth's environment is such a big part of our past contribution, not just the accumulated CO2 and methane. So if we wet out to reverse our contribution, not only must we remove trillions of tons of CO2 from the air, but we must also cool the air, cool the water and land.

When someone sets out a plan to do that, we can take responsibility for the past contribution.

Until then we take responsibility for only future contribution. Stopping all of our future contribution will slow but not stop global warming.

Earth has clearly gone, repeatedly, from ice age to prolonged warming and then into a period of widespread global warming and then an ice age again. This is not in dispute.

All that is in any dispute are questions like, are we at fault, and can we stop it.

We know that GHGs do trap long wave energy, and so cause heating of earth. We know we have been contributing that. That is not in doubt.

We can say with 70% or more confidence that elevated GHG has caused a recent increase in rate of temperature increase despite a recent reduction in solar output.

What is far less evident is whether global warming may also have contributed significantly to  accumulation of GHG, in addition to the amount we have contributed. Based on previous cycles, we should expect to find that non human causes will have contributed a lot, too, or will soon do so as temperatures rise.

Answer 8

What I think is of no consequence, the earth's climate will change, and those changes will come about from many different factors, since we are indigenous to this planet we are a part of the natural order of things.

Answer 9

Here is truth about global warming:

Global warming is one-half of the climatic cycle of warming and cooling.

The earth's mean temperature cycles around the freezing point of water.

This is a completely natural phenomenon which has been going on since there has been water on this planet. It is driven by the sun.

Our planet is currently emerging from a 'mini ice age', so is

becoming warmer and may return to the point at which Greenland is again usable as farmland (as it has been in recorded history).

As the polar ice caps decrease, the amount of fresh water mixing with oceanic water will slow and perhaps stop the thermohaline cycle (the oceanic heat 'conveyor' which, among other things, keeps the U.S. east coast warm).

When this cycle slows/stops, the planet will cool again and begin to enter another ice age.

It's been happening for millions of years.

The worrisome and brutal predictions of drastic climate effects are based on computer models, NOT CLIMATE HISTORY.

As you probably know, computer models are not the most reliable of sources, especially when used to 'predict' chaotic systems such as weather.

Global warming/cooling, AKA 'climate change':

Humans did not cause it.

Humans cannot stop it.

Answer 10

well its a little of both but mostly man kind the natrural part is things like goats burping but its mostly human because any thng gas powered releases Co2 which you should know by now is a green house gas and keeps sunlight from entering the atomosphere.

Answer 11

The scientific data proves it's mostly (75-90%) us.

Short version here:

Long version:

This is science and what counts is the data.

"I wasn’t convinced by a person or any interest group—it was the data that got me. I was utterly convinced of this connection between the burning of fossil fuels and climate change. And I was convinced that if we didn’t do something about this, we would be in deep trouble.”

Vice Admiral Richard H. Truly, USN (Ret.)

Former NASA Administrator, Shuttle Astronaut

Here are two summaries of the mountain of peer reviewed data that convinced Admiral Truly and the vast majority of the scientific community, short and long.

There's a lot less controversy about this is the real world than there is on Yahoo answers:

And vastly less controversy in the scientific community than you might guess from the few skeptics talked about here:

"There's a better scientific consensus on this [climate change] than on any issue I know...  Global warming is almost a no-brainer at this point.  You really can't find intelligent, quantitative arguments to make it go away."

Dr. Jerry Mahlman, NOAA

Answer 12

Normally climate change occurs naturally.  However, the current global warming is different.  We know it's almost entirely caused by man.  For details on how we know this, see the link below.

Answer 13

Both more natural then manmade

Read this article from the founder of the Weather Channel John Coleman:

And as much as the alarmist hate it, I would suggest perusing Junkscience.com, and look at what skeptics are saying instead of listening wholesale fluff presented by the simpletons, who fail to look at science as a critical study of such questions.

1. Global Cycles -

      a. apogee/perigee orbits around the sun,

      b. Solar and solar storm cycle (evidences supports this, by increase   temperatures on other planets (such as evidenced on Mars).

http://news.nationalgeographic.com/news/...

      c. Natural Cyclical climate patterns,

One Fact the alarmist fail to mention when spewing their mantra is that global mean temps have fallen not risen since 1998.

The economic boondoogle adopted the Al Gore model would  ruin the economies around the globe.

Look , I was a natural resource major in college back in the 1970s the prevaling wind at the time in our climatology classes was the earth was in a cyclical cooling period.

We are in geological what is called the "interglacial period". very much like the holocene, of 40,000-5000 years where temperatures generally warm, these periods through out the last 10M years correlate with solar apogee/perigee.. with fluctuation in period that are strongly influence by the Maunder min/max periods of solar activity.

In a microclimatic sense, yes, atmospheric gases do play an influence, as does lack of green cover in metropolitan areas.

the biggest contibuter of greenhouse gas is water vapor,

Atmospheric CO2 has such a slight influence it was not generally mentioned..

Al Gore's tree cover suppositions are false as well. Forestry companies around the globe are for the most part working under a 100% sustainable model. Google Weyerhauser, Georgia Pacific, and other companies, all have detailed reports of their sustainable yield program.



The "models" used by Al Gore to show in his movie are inherently flawed because of statistical modality.  He or whoever was creating the model skewed the data with the

the peck of a keyboard.  And by default because Al Gore says it's so, 1/2 the world population "believes" it. It is at this point, BELIEF, a very strong word enters the picture.

Pariahs like Milloy, Michaels and Balling are castigated because they believe it is important to make sure the data is not flawed, and based on their subsequent studies have proven Al Gore a liar on several of his key figures.

When does a hypothesis/theory become a scientific fact? It becomes a fact when it is proven beyond doubt. This in my view has not occured.

it is not something that should cause panic or fear.. Panic and fear are tools used by political powers..
