Is there any evidence that proves global warming?

Question

Actual evidence in the form of studies, scientific reports and so on; not hype or propoganda.

Answer 1

Global warming is clearly not natural. Here's some hard facts, with references. Not idle speclation, facts. The first report is the authoritative document, full of data. It's a 21 page summary, the 1600 page full report will be out soon with voluminous data as proof.

Lots of data here. For example, changes in solar radiation are 0.12 watts per meter squared, while changes due to man are 1.6 watts per meter squared, more than ten times as much.

The report also shows the warming is extremely fast. It's much more rapid than any "natural cycle".

And this graph of CO2 is very enlightening.

The little teeth are the natural "carbon cycle". doing its' thing. CO2 goes down a bit in the summer and up a bit in the winter, consistent with plant activity. The large trend upward is us. We're digging up carbon the natural cycle buried over many many years, and burning it real fast.

Volcanoes are insignificant compared to the effects of man:

Which is why most all scientists agree global warming is real and caused by us.

http://www.sciencemag.org/cgi/content/full/306/5702/1686

They surveyed all 928 papers published between 1993-2003 that contained the words "climate change". The number that said global warming was natural? Zero.

"there is a scientific consensus on the reality of anthropogenic climate change. Climate scientists have repeatedly tried to make this clear. It is time for the rest of us to listen."

"the question of global warming was settled years ago for all but a few holdouts in the scientific community"

Unfortunately, we're kicking nature's butt on this one.

Answer 2

Yes, check out the recent IPCC report on global warming published in 2007. Plus there have been hundreds of studies that have demonstrated the phenomenon, but fewer that have linked human activities. As a scientist who is active in this field I know of no study that has been published that refutes the warming that has occurred over the last century.

Answer 3

The change in climate has been going on for billions of years so it seems a no brainer. But, the question seems to be how much effect human tinkering has on the current climate. Mankind has radically changed the biosphere by chopping down forests and filling wetlands to provide room for human needs. This has been going on for thousand of years and there should be something done to restore a balance don't you think? You don't need to do a lot of things that cost in one way or another but good engineering needs to be used to fix this problem. It is very fixible and when done will be good for everyone. More wealth and more health for all.

Answer 4

almost 100% of scientist agree that globa warming is man made, there are hundreds of thousand of reports ect dealing with this. eg Stern report, report by the United Nations, last week, The reports made byNASA which george bush ordered his lawerys to alter

Answer 5

read plan B by Lester E Brown
here are some details of what has happened

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
