where can I find scientific evidence that humans are contributing to global warming?

Question

I want to defend the position that humans are contributing to global warming by using scientific evidence and peer reviewed articles. Damn near everything I can find on line is just people jabbering their un-scientific opionions. I want some hard proof. can anyone point me in the right direction. (this is for me to disscuss with my friends, not for anything acedemnic or profesional)

Answer 1

The single best source available on human caused climate change is the IPCC report. Everything in the report is fully peer-reviewed and sourced so you and your friends can fact check it if you want to. You can read the whole thing online for free here:

http://ipcc-wg1.ucar.edu/wg1/wg1-report.html

An excellent book on climate change is the 'Rough Guide to Climate Change' by Robert Henson. The book isn't peer reviewed but all the data in it is, and the book contains pretty much nothing but the science.

http://www.amazon.com/Rough-Guide-Climate-Change-Reference/dp/1843537117

And if you'd like to read counter-arguments to the objections raised by opponents of the theory, the best site I know of is RealClimate.org, a site run by fifteen highly qualified climate scientists.

http://realclimate.org/

However, the articles on RealClimate can get somewhat technical, so another good site refuting the skeptic's claims is A Few Things Ill Considered, which is a Blog run by an interested layman. The guy running the site isn't a scientist, but he cites everything he says with fairly comprehensive sources.

http://illconsidered.blogspot.com/

Of course, you can't be expected to effectively argue for a theory unless you understand its history now, can you? So here's a marvelously comprehensive history of global warming theory, from its origins in the late nineteenth century to the present day. The site was written by a physicist and science historian, has loads of links to scientific information on GW theory, and is one of my favorite sites on it out there. If you only read one of the links I've given you, make it this one.

http://www.aip.org/history/climate/co2.htm

And finally, here's a whirlwind tour of Earth's climate history. The article is very well sourced to peer reviewed information, and will give you lots of background information on the planet's climate when trying to argue the theory.

Answer 2

Well young person.... you've discovered the ugly truth about this issue. There is no hard 'scientific' evidence that humans are significantly contributing to global warming. There are just a lot of coincidences and inferences. There is no doubt that human activity is contributing to global warming, in that we create CO2 and other so-called 'greenhouse' gases. The question is whether or not the other known major contributors such as forest fires, volcanic eruptions, cow farts and the decay of organic matter, so dominate the situation that the human contribution is negligible. The real problem is that the politicians and activists would rather not consider the possibility that climate change is beyond human abilities to control or even modify . It's much more palatable (and profitable) to believe that if we all just work together and stop being nasty capitalists, the world will continue on being its old pristine self forever. ==== If you actually read the source data, even that of the UN and US Government, you'll see that the whole proposition is smoke and mirrors. Sorry Al.

Answer 3

An inconvenient Truth by Al gore has the data you need.

There is some data missing from there. They base the tempature, methane, and co2 levels off of ice core samples.

The thing is that I theorize that in points in earths history it got so hot that the water covers the ice caps, blocking the formation of new ice and the airborn data from the trapped bubbles.

So what that tells us is that when we peak the methan and co2 outputs to the point where the planet is too hot, no ice forms. I can tell you this, we are almost there.

It has happened over and over again on this planet, we know that we are going to flood, we need to do something about it.

2040 is right around the corner, and so is 1 billion environmental refugees.

We may be too late to stop it, we may not even be the real reason for the increasing temperature, it could be cyclical.

Perhaps that is what the pyramids around the world were meant to tell us.

Either way, we need to end the war and start preparing for what we know is coming. It is time to start listening to the scientists.

Answer 4

Start at the URL's below, and follow it as far as you want.

There is still dissent, but it's a very small voice now.
And the human-caused global warming view has established itself *against* what was the firm consensus 25-30 years ago when the expectation was for a new ice-age.

Answer 5

Where can I find evidence that liberals are contributing to the global warming scam? Easy. I just have to look for nuts like you.

Answer 6

good luck its the biggest controversy that's going on.
the main disagreements are as to who or what is responsible

some still believe that nothing is wrong ,they will also be convinced when the price of food and beer hits the roof ,because of third world problems in food production and Global potable water shortage

as for the rest of us ,
can we do something about it?
I dont think so ,but we can behave more responsibly in out behaviour towards the Environment ,maybe we can buy some time

are We responsible ?
or is it God who wants to punish?
or is it Gaia who wants to clean some parasitic infestation?
who cares ? that is not important any more

WHAT IS -is that we are gonna be in trouble

The Earth has many problems because of man
this is undeniable ,how much we are responsible for Global warming is debateble ,But there is a definate change in Global temperatures that is affecting nature in a bad way.

this text only covers some aspects of Climate change ,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

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

And now many animals are becoming sick because of changes in temperature ,
vital links in the food chains are disapearing affecting other species further along in the chain

90% of the feral (wild) bee population in the United States has died out.

In the Netherlands bee diversity is down 80 percent in the sites researched, and "bee species are declining or have become extinct in Britain."

wildflowers that depend on pollination have dropped by 70 percent

we are witness to a mass exstinction ,for the first time since the dinosaurs, of the earth's estimated 10 million species, 300,000 have vanished in the past 50 years. each years, 3,000 to 30,000 species become extinct.

everything is happening so fast it is not possible to monitor things any more.

,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 few 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

You can't find it. Humans have nothing to do with it. (If it does happen to be true.)
