Global warming, nature or human fault?

Question

Is global warming human fault or morther nature taking its course?

The Earth is in an interglacial period now, the last retreat ending about 10,000 years ago. There appears to be a conventional wisdom that "the typical interglacial period lasts ~12,000 years" but this is hard to substantiate from the evidence of ice core records. For example, an article in Nature argues that the current interglacial might be most analogous to a previous interglacial that lasted 28,000 years.

Based on predicted changes in orbital forcing, in the absence of human influence, the current interglacial may be expected to last 50,000 years: see Milankovitch cycles. However anthropogenic forcing from increased "greenhouse gases" probably outweighs orbital forcing and the prediction for the next few hundred years is for temperature rises.

The Romans gre vines in the UK and we are only just able to do the same.

Answer 1

Hehehe. Actually, nobody really knows the answer to the question. Al ('I invented the Internet') Gore claims to, but he's a no-brainer dweeb with a lot of other agendas.

You mentioned orbital forcing, but did you know that the average Solar output (radiance) has gone up several tenths of a percent in the last 50 years or so? And there's not a damned thing we can do about that (except ride it out ☺)

I might desire to disagree with Smilelts. no longer each and every scientist concurs it relatively is human brought about. regularly this is the media who will air purely the pro-human-brought about voices of technological know-how. it relatively is what the media does. They feed off the alarmist element of human nature. yet there are basically as many specialists that disagree. The Earth has long previous via many climate differences in the previous. curiously that the traditional climate is relatively tropical, and replaced into for some 3 hundred million years. To the quantity that there are palm and fern fossils latest in Antarctica. The alarm that we are loosing the ice on the North Pole has quieted some this previous iciness, simply by fact the ice sheet replaced into prevalent this time. The media would not choose for to communicate approximately that. lots of the west Canadian glaciers that have been mapped in the 1850s have been the two long previous or almost long previous via 1900. back, this education is obtainable. It basically takes slightly extra attempt to detect.

Answer 3

How many times?
Humans pollute and destroy and yet you think that will have no effect on the environment we are a part of.
We are not above the system we live in. Everything we do affect it, and our environment affects us. It is a pretty simple concept to grasp!

Answer 4

Since there is more evidence that shows that the sun is heating up, and that Mars is also experiencing "global warming", I believe that it is almost 100% nature, and not man to blame. That's all I'm going to say about it.

Answer 5

Human. Nature tries to heal it.

Answer 6

this world is not perfect anymore because of sin. sin not only affected humans but also the world we live in but humans are at fault too.

Answer 7

Nature, Duh, we haven't been able to record the earth temperatures that long, we're looking at a very small time period in human history. Although, we can do a better job at keeping the earth clean

Answer 8

Nature .. because our world is getting old and Human are helping to make it worse...:)

Answer 9

I know youre not askig everyones opinion. Twenty to one though if we werent here we wouldnt have to worry about it.

Answer 10

Is global warming a man-made menace?

not all 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

some home truths

politicians and scientists who work for politicians have downplayed the facts because solutions are expensive and means change and change effects many people income,and most of the world is kept in the dark of the real things that are going on.


in North Africa,India,Mexico ,millions of people are effected by land loss and desertification


in recent times thousands of people have died because of exessive heat,usually old people.in India ,Mexico and France,
deforestation causing desertification,the desert conditions causing very cold nights and scorching hot days

in china, thousands of what used to be farmers are running for their lives from the dust storms that have burried their towns and turned their lands into dessert,the globe where they were got to hot for them .
and instead of producing food they are now needing it from some where else,and they will drastically effect the world food prices when they start buying water in the form of grains ,at any cost destabalising governments, in some countries ,could be the result
(are you seeing more Chinese around interested in agricultural lands ,we do here in Mexico)

,the Sahara is growing by 7 kilometers a year
and all 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 because of bad farming practices like,over grazing and fertilizers,

as far as the food production is concerned, Global warming or some of its effects are serious,rising seas result in landloss

each degree rise in temperature means 10%crop loss

more landloss because of desertification every year,we have less areble land to produce food ,for an extra 70 million people ,

and there is less and less water (because of deforestation),to irrigate this production ,
and there are less and less farmers to do it..
who are overpumping deep carbon aquifiers
who are plowing more and more unstable lands because they have lost so many million hectares to desertification ,
because of bad farming practises ,such as using fertilizers and heavy machinary or over grazing

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 is in theory reversable,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.

SOLUTIONS
if you want to help the planet ,plant a tree every week ,if everyone on the planet did we we would be able to reverse the destructive processes

reduce carbon emisions,and they are already working on that by alternative forms of energy and regulations on carbon producing materials,aerosol cans,burning rubbish,industrial chimneys,powerplants etc.

the capture of carbon and the production of water and assist the aquiferous manta.

the world bank pays large subsidies for reforrestation to capture carbon and the best tree for this is the Pawlonia

Waterharvesting projects ,such as millions of small dams.to redirect over ground waterflows from the rains into the ground to supply subteranian water supplies.

the protection of existing forrests.

stop building more highways,urban planning to include vegetation stop building cities encourage people to return to the land to conduct their business from there which now has become possible thanks to the internet.

education to motivate people to auto sufficiency by building more home food gardens.

education on environmental awareness
education on family planning to curb over´populaion

Agricultural education and improvements to follow the principals or sustainability and soil management.

more environmental or land ,design to prevent bush fires,such as--fire breaks

,more dams.regulations and control for public behaviour

alternative effeciant public transport to discourage the use of the internal conbustion engine

recicling wastes,limit water use
