Are humans solely responsible for Global Warming?

Question

It is easy to find reasons that support how humans have caused global warming, I would like to know if anyone has strong reasons opposing this current belief.

Answer 1

Humans are not solely responsible for global warming.  Global warming is a natural cycle, but humans are greatly speeding up the process.

Answer 2

Not solely.  It's mostly humans, and about 10% the sun.  Volcanoes are insignificant.  They emit far less greenhouse gas than man, and what they do emit is about cancelled out by the dust from an eruption.

Here's the actual numerical data, including volcanoes, the sun, etc.:

Answer 3

jeez.  of course.  we've been saying it for years.  the only people that don't think so are the ones that listen to rush limbaugh.  morons.

Answer 4

there is a lot of evidence of man made climate change .and there are many reasons to hide the truth

scientists who work for politicians ,get paid by these politicians and they have downplayed the facts because solutions are expensive and means change and change effects many peoples incomes,and upsets profit margins,so most of the world is kept in the dark of the real things that are going on.for political and economic reasons

Global warming is a very complex collection of many effects

this text only covers some aspects of global warming ,mainly agriculture i.e.effects of deforestation and subsequent man made desertification

water and air polution such as caused by

industrial contamination ,the contaminating effects of the cities(the internal combustion engine) ,are other stories,

and all of these are also man made ,such as the high industrial chimneys pumping contamination into the clouds and the burning of tires,some of this polution has been found in the ice in the polar regions

there are natural cycles in the planets life

but a lot is influenced by mans existance ,and this is increasing with overpopulation,putting strains on Natural resources and increasing contaminations as well as destructions of essential componants the ensure living conditions for all life forms

climate change is caused in great parts by desertification ,and most desertification is caused by man

the thinner ozone layer helps to speed this up.and this is caused mainly by air polution ,also as a result of mans actions

DEFORESTATION

in the past

the Building of the Spanish Armada deforrested Spain

the Phoenician trading fleet turned Lebanon in a dessert

Ganges Khan put everything to the sword and torch, then filled the wells with sand,

the sun finished of the job and whole countries turned to wastelands.

Today ,

Slash and burn destroys the protective vegetation (which helps to form the soil ),

leaving it open to the Sun ,and then ,wind and, water erosion.

The Plough turns the soil ,killing micro-biotic life (essential to soil building) and accelerates the drying out .

Pressures of the :vehicles, cattle and rain impact brings the salt to the surface.

Mono cultures ,aided by chemicals Exhaust and pollutes the soil .

Adding to this the effects of overgrazing has resulted in large scale desertification.

and there is less and less water (because of deforestation),to irrigate this production ,Farmers

are overpumping deep carbon aquifiers

and plowing more and more unstable lands going into the jungles and onto mountain slopes

expanding populations and expanding farming ,that has to keep pace with the expanding populations are very strong forces that encroach upon the rainforest's

clearing them for farming and settlement areas .

Rainforest's always are in third world countries and always in third world countries corruption and the need for money s highest

in North Africa,India,Mexico ,millions of people are effected by land loss and desertification and some have died as a result

,the Sahara is growing by 7 kilometers a year

and most of the desserts we know are a results of mans actions ,and they are increasing ,not getting less ,in the dinosaurs days ,there were no desserts.

collectively this planet is drying up ,

each degree rise in temperature means 10%crop loss

and there is less and less water (because of deforestation),to irrigate this production ,

and there are less and less farmers to do it..

Arable lands and their farms are lost all over the globe. Many farmers sons abandon farming and head for the cities.

Northern China is drying up, what once were millions of food producing people, are now hungry refugees ,running for their lives from the all consuming dust storms.

This will have a great effect on world food prices when they start buying at what ever cost, to feed their people.

The farmers that are left have to feed some 70 million more people than the year before but with less topsoil.

Over the last half century,

Population growth & rising incomes have tripled world grain demand from 640 million tons to 1,855 million

In the near future the global farming community will not be able to feed every body ,food prices will continue to rise. .

RISING SEAS

The northpole is melting ,and we will know it without ice in our life times.

this does not affect the sea level because it is ice that is already in the water.but the melting ice from Green land and the south pole ,are another matter

Global warming could be slowed down to some extent,but it will mean global co operation between all countries ,and taking into account human nature and the world politics ,it is unlikely that this will happen,

At least not untill we are all in the middle of planetary disastres and it becomes a battle for the survival of humanity every where,instead of just some third world countries Source(s) here are a 100 ways to help

Answer 5

Once upon a time humans thought the earth was flat, just like any other manmade scientific theory,  the concept of global warming may one day be proven false.  

To what extent humans contribute to "global warming"  is very little incomparison to volcanic eruptions. Prior to the ice age the earth was in a tropical state-(ie tropical vegetation  found in the stomachs of Wolley Mammoth fossils in Siberia. )  

I believe the earth is in a warming cycle, independent of man's existence on it.
