Is global warming caused by man?

Question

or is it , as i reckon just a natural cycle, by putting your plastic waste seperate from your metal waste aint gonna make a blind bit of difference.

Answer 1

Absolutely not!

As Dr.Jello says this is a 'natural process'.

Mankind's impact is insignificant to say the least!

I encourage all recycling, not to 'save the planet',but because I hate to see waste of any kind!

The fact is that even if we all recycled as much as I do (three plastic garbage bags in three years), this would have no impact on a global scale!

Any lunatics who think that they could come close to my record are either lying, or have a better system than I do.

I would  still ask anyone who has the opportunity to recycle, to do it because it costs much less energy  to produce something from an existing item than, than to produce it from it's original ore! (Theoretically saving us money)

Answer 2

There are many people who say yes and many who say no.  The earth goes through many changes as we can see from graphs and charts, we have had hot periods and ice ages, in my opinion we are hurting the environment with pollution, we can see this with endangered species etc. However as far as climate change in concerned, i believe we have a little impact but also that the earth's temperature is naturally rising as well.

Answer 3

Seriously!!! Can we stop asking this, you people probably think the world is flat too. Yes, we caused global warming.  There is no natural precedence for what we are seeing. The cycles people refer to with the heating and cooling phases of the planet are many tens of times more subtle than what we have seen recently. Couple that with the fact that the last 100 years has been one of only 5 great periods of extinction on our planets history (This one being the most rapid). Then see that the reasoning is sound and the fact that despite conservative wishes there have been tens of thousand of studies showing our effect and not a single real scientific study that countered the claim and I'd say,

well I'd say the Earth is not flat!

Answer 4

for thousands of years the earths climate a changed drastically, if we consider the time the earth has been around as a day then we have been on this earth for less than a second. I do not for one second believe we can have an impact in that short a time. On top of which it seems a bit strange to me that in the Uk and probably Europe and the USA  only scientists who admit that we are the cause of global warming are eligible for government funding

Answer 5

Not wholly, but man do play some part in global warming.

Answer 6

Are we the sole reason the Earth's average temperature has raised and the polar ice caps are melting?

No.

Are we contributing to it?

Absolutely.

No one can really prove anything, so my personal theory is that the Earth has a natural cycle, and we were caught in it's mild parts.

Answer 7

a LITTLE is caused naturally.  there is methane gas rising from the artic tundra.  but, id say almost all of it is caused by humans!  due to over pupolation and poluttion this land is trash!  and karma will be coming back around, global warming.

Answer 8

The current warming is caused mostly by humans.  See the link below for a scientific explanation of how we know this.

Answer 9

Global warming is not caused by man. MAN CAUSE THE OZONE LAYER TO DISAPPEAR, thats why this depletion of the ozona layer is causing global warming. Yes, we are indirectly causing global warming. Many people wonder why we still have to 'save the earth' when we NEED to use those rubbish and paper for our daily needs, but the problem is, are we using it over excessively? Do we at least TRY to re-use plastic containers and bags whenever we can? I dont think many people care. Thats why global warming is partially caused by man.

Answer 10

human is too small to have effect on earth.

It is a propaganda to make factories buy new technologies therefore have lots of sales and benefits. thats it

Answer 11

Your reckoning is correct, It's a natrual cycle. As for recycling? If you have the ability to do so go ahead, if not, don't beat yourself over the head that you don't have the means to recyle. Since most apartment complexes don't have proper recycle bins.

Answer 12

The only people who think Global Warming is in some way a natural phenomenon are those with a vested (i.e. financial) interest in maintaining the status quo.  Unfortunately there are far too many lazy people prepared to believe them if it means they can keep their car and not go to the effort of recycling.

Increasing Global temperature correlates directly with Carbon Dioxide content of the atmosphere which in turn correlates directly with industrialisation and energy use since the mid 18th century.  That, I am sure, is proof enough for anyone.

Answer 13

Only a very small insignificant part

Answer 14

Graphics from Intergovernmental Panel on Climate Change Report Summary



Global warming -- a gradual increase in planet-wide temperatures -- is now well documented and accepted by scientists as fact. A panel convened by the U.S National Research Council, the nation's premier science policy body, in June 2006 voiced a "high level of confidence" that Earth is the hottest it has been in at least 400 years, and possibly even the last 2,000 years. Studies indicate that the average global surface temperature has increased by approximately 0.5-1.0°F (0.3-0.6°C) over the last century. This is the largest increase in surface temperature in the last 1,000 years and scientists are predicting an even greater increase over this century. This warming is largely attributed to the increase of greenhouse gases (primarily carbon dioxide and methane) in the Earth's upper atmosphere caused by human burning of fossil fuels, industrial, farming, and deforestation activities.

Average global temperatures may increase by 1.4-5.8ºC (that's 2.5 - 10.4º F) by the end of the 21st century. Although the numbers sound small, they can trigger significant changes in climate. (The difference between global temperatures during an Ice Age and an ice-free period is only about 5ºC.) Besides resulting in more hot days, many scientists believe an increase in temperatures may lead to changes in precipitation and weather patterns. Warmer ocean water may result in more intense and frequent tropical storms and hurricanes. Sea levels are also expected to increase by 0.09 - 0.88 m. in the next century, mainly from melting glaciers and expanding seawater . Global warming may also affect wildlife and species that cannot survive in warmer environments may become extinct. Finally, human health is also at stake, as global warming may result in the spreading of certain diseases such as malaria, the flooding of major cities, a greater risk of heat stroke for individuals, and poor air quality.

Climate change is very likely having an impact now on our planet and its life, according to the latest installment of a report published by the Intergovernmental Panel on Climate Change (IPCC). And the future problems caused by rising seas, growing deserts, and more frequent droughts all look set to affect the developing world more than rich countries, they add. The report is the second chapter of the IPCC's Fourth Assessment -- the most comprehensive summary yet of research into the causes and effects of climate change.

PEOPLE ARE CAUSING GLOBAL WARMING AND SO IS EARTH ITSELF.

Answer 15

Recycling is a good ideal, global warming caused by man, no we are just making a tiny contribution to a natural cycle, in a few years when the weather starts to reverse all the greens will be shouting "look what we've done we were right all along", the sad thing is they'll believe it.

Answer 16

Global warming is but a component, in a group of destructive forces at work such as ;deforestation,desertification,Subsequen... wind and Water erosion,soil and water contamination ,irresponsible or wasteful utilization of bio resources and air pollution.

WHICH WE ARE RESPONSIBLE FOR.

in the last 300 years half of the planets forests have gone

and in the last 50 years

half of our wet lands ,rain forests and ice fields .and 3000 species of animals .

Having changed so much of nature into concrete or tar ,and removed so many forests that absorb heat during the day and release it at night as well as the absorbing of carbon .And so regulating climates

Also the precipitation which makes inland rain and keep rivers flowing.

The result of extensive deforestation is ,that rivers dry up ,

This is not helped by Man over pumping Carbon aquifers for irrigation.

We must have had some effect on the climate to say the least

Not to speak of air pollution .and Global warming that comes on top.

Watch a BBC documentary by David Attenborough

he did about 15 movies called Planet earth

the ones called Future ,the ice worlds ,from Pole to Pole ,

covers the poles and shows footage of polar bears swimming

All 15 movies are great these people have been making nature movies for many years and they show and talk about the differences of what they see today ,

compared with before

They say whole migrations of millions of animals in the tundras have disappeared in just 5 years.

And everywhere they go people talk about certain species not being there any more..

thousands of species of frogs have gone ,world wide.

this is very significant because they are indicators of pollution because their skin is very absorbent,and they are sensitive to environmental changes.

The increase in water temperature will get faster all the time as well as the melting, when the ice is all gone the deeper cold Ocean currents will be drastically affected,which in turn will affect the warm currents,since all moving bodies of water are connected in series.

This will affect coastal climates ,world wide ,almost instantly. All aquatic flora and fauna will be affected,many dying off and others becoming invasive,

And recently In Chiapas ,and Tabasco in Mexico .more then a million people became homeless overnight with water coming up to their roofs ,because of rains from super evaporation from the forests,this had never happened before. Millions of animals died.

In India 3000 people died because of super storms .

.A few years ago in Europe 3500 people,died during a heat wave ,many of them in France .

Right now the average death toll annually is 150.000 due to Global warming

. these figures are already out of date and are expected to double soon.

In Northern China millions of people are running for their lives because regular dust storms so far have buried 900 villages under the sand and the whole of northern China is turning into a dessert.

The Sahara is growing by 7 kilometers a year all around the edges ,like a slow burning fire shriveling up their neighbors In the Kalahari huge rivers have dried up and thousand of species are gone due to their habitats disappearing .

The biggest changes are invisible at micro biotic levels species are becoming extinct ,others are multiplying ,

This affects the insect populations that follow ,and changes in that ,affect all that follows in the food chains ,

We are now witnessing a mass Extinction of animals and plants of Biblical proportions,equal since the disappearance of the dinosaurs

.

Whole migrations of animals involving millions have disappeared in only 20 years,

in one place in the tundras ,in just 5 years

CHECK THE CLOCK FOR THE SPEED

If we want to save ourselves as a specie ,we have to address

the problems

We can correct most of the destructive factors

with disciplines ,changes of attitude and habits,alternative energies ,sustainable design etc.

All species are in Danger eventually,and each is important because all of Life on this planet is interrelated even if it is not obvious

Imagine that the Eco system is a wall and each specie is represented by a brick

Every brick taken out weakens the wall ,and eventually it will collapse ,which brick is the most important ???

they are all important and we are one of the bricks

Answer 17

Global warming iz caused by.......man,because da melting of glaciers cause the pollutions and fumes 2 go 2 our ozone layer and put a hole in there.

Answer 18

part of it

Answer 19

Is global warming caused by man?

yes, and a bit by women too.

Answer 20

yes,man is responsible for causng global warming.....

man is cuttng trees which increases carbon dioxide in the atmosphere......which is a green house gas responsible for increasing temperature and burning of fossil fuels plastic bags releases gas which causes global warming

Answer 21

Currently there are more and more scientist who see the Sun as the source for all warming on Earth.

Man is too small to have any impact on something as large as the climate.
