What do you think... Is Global Warming Man-made or natural?

Question

Be very political if you want. Haha.

Politics owns

Answer 1

Global warming is but a component, in a group of destructive forces at work such as ;deforestation,desertification,soil and water contamination ,irresponsible or wasteful utilization of bio resources , air pollution,Non sustainable Agriculture,over pumping carbon aquifers

all concepts which are definitely not part of the Natural Processes of the Natural world

WHICH WE ARE RESPONSIBLE FOR,

The most prolific growth on this planet is part of the day in the mist and most of the time under clouds ,and the least growth is always directly in the sun .

To exchange the one for the other means changing local climates

We are exchanging Nature with Tar , concrete and open spaced mono cultures.

In 300 years half of the planets forests have gone ,and in the last 50 years half of the wet lands ,and rain forests

These Areas absorb heat during the day and release heat at night ,

Cause cloud formation(shade).humidifying the air on the surface as well as releasing excess water at the roots that keep rivers flowing ,which in turn brings more water into the Environment .

As well as contributing to absorbing carbon emissions as do the leaves of the trees together with the oceans .

All in all many factors which directly affect the local Environment .

The loss of the above resulting in rivers drying up ,less rain ,desertification,loss of habitat for many species and so on.

dryer and hotter surface environments which can manifest in different weather patterns such as tornadoes or bush fires

I may be stupid or Naive but somehow i believe that lots of these local environmental changes, can add up to affect global weather, If there are enough of them (and there are)

And then on top of that comes the story of the effects of pollutants released into Nature and especially the Air ,by MAN ,http://earthissues.multiply.com/photos/a...

And then there is of course Global Warming lets say the Natural one

(Bob or Trevor can talk better about that )

A cocktail of events and a lot of the ingredients have MAN written all over them

So it is safe to assume that we should look at ourselves ,just a teeny bit ,for possible improvements ,and rectifying Eco errors that are with in our powers.

What is a safer bet

to be or not to be

Answer 2

of course it's natural. it's also man-made (at least partly). the terms are not opposites, at least not the way i understand them.

Answer 3

Mostly man made.  No politics here. 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 4

It's the earth's process, but we are speeding it up immensly and making the world hotter than it's ever been. It's natural, but it's not supposed to be like this

Answer 5

It's natural. Look up "Global Warmng is natural" on google. You'll find many intellectual arguments that Global Warming is a natural event.

Answer 6

yup it's political alright!

it is natural and the earth temp has cycled ever since the beginning.

Answer 7

This is the greatest hoax since Chamberlains, peace in our life time speech.  Funny how many can cut & paste answers but never author any of their own. I'm no skeptic, I flat out denounce it as junk science.

Answer 8

It is both but mostly natural so far.

Answer 9

Its both.

Answer 10

Natural.

If it was man made why would Mars also be warming?

Answer 11

All climate modelers must build their models based upon our current understanding of how the climate system works. Therefore, if there is some important - but as yet poorly understood - process that they are missing, they will all tend to make the same error. Past evidence for this is the tendency for climate models to drift away from a realistic climate over time. This suggests that it takes a higher level of understanding to capture the intricate processes that stabilize the climate system.

The most important example of this lack of understanding is, in my view, how precipitation systems control the Earth's natural greenhouse effect, over 90% of which is due to water vapor and clouds. The Earth's total greenhouse effect is not some passive quantity that can be easily modified by mankind adding a little carbon dioxide -- it is instead being constantly limited by precipitation systems, which remove water vapor and adjust cloud amounts to keep the total greenhouse effect consistent with the amount of available sunlight. Our understanding of this limiting process is still quite poor, and likely not represented in climate models.

The vast majority of climate scientists are not climate modelers, and they will tend to go along with what the modelers say. After all, it is the modelers who are supposed to gather all of the specialized knowledge of how weather processes operate, and then represent them in a computer program (model) of how the whole climate system behaves. Thus, there is an element of "group think" that keeps scientific biases entrenched in the research community as a whole.

Answer 12

the funny thing is that the hottest climate the US has ever had was in the early late 18 early 1900's. Michael savage read out a list of many many city's with all having highest temp records set 80-100 years ago. And also remember the ice age? It lasted millions of years, its gonna take millions to raise the temp back up LOL. But yeah we do put green house gasses in the air but then there are these things called plants that turn CO2 into O2! So really the world is taking care of that problem on its own. Another fact: when mt st helens erupted, the amount of greenhouse gasses in the atmosphere doubled in one day! All of human activity's green house gas contribution since we started burning fossil fuels was matched in one day by one volcano. The world didn't end, the ice is still there, the wales and seals are still mating and nothing changed. Maybe because of plants that can help filter it! Global warming is just liberal agenda trying to get you on board with their plans and bills which is just another reason for them to raise taxes and sucker us out of our money. Better world is achieved through less govt

Answer 13

natural... the ice was suppose to melt sometime..

Answer 14

It's natural, we have been cooling for the past decade but that isn't getting much media time is it. And in that same time period the amount of carbon dioxide has increased at an even greater rate.

Answer 15

No reason to get political when the answer is determined through science.  Normally climate change is natural, but this time is different.  See the link below for an explanation of how we know this.

Answer 16

Personally, I believe it is a combination of both:  man-made problems and weather cycles.  Here's an interesting thought to go along with youy question.  We are informed that the glaciers are melting, ergo the polar regions are getting warmer.  Are the deserts getting hotter too?  Also, wouldn't it help the world's population if more room to live and cultivate is gained from warmer climates at Antarctica?

Answer 17

The Sun of course is the primary source of warming of the Earth, without it, the temp would be 0 Kelvin or -459F. The climate is also fluid depending on many variables from fluctuations in orbit and minor changes in solar output to Volcano’s that can cause cooling. Yes Human influence is noticeable and the effect is tiny if you use -459 as a starting point and get the current avg temp of the earth ~14c the amount humans have effected the whole is less than 0.2% a tiny amount. Yes there are natural cycles but they happen over 10's of thousands of years not 1-2 hundred.
