Is global warming even real?

I'm not sure who to believe on this subject, I've heard that the climate has changed before and that the ice caps have even melted before, but global warming is still being mentioned and governments are even trying to take action against it, there are people who say that it's a scam, but some of these people seem to be the same people who think that the music industry is controlled by the illuminati, so I'm not sure how seriously to take them, is it real?

Global warming is very real, but is not caused by humanity, as the current warming trend, that includes massive glacial melt, has been in effect for 20,000 years, or since the coldest part of the last ice age. 20,000 years ago, one single glacier, extended into New Jersey, near where I live, it also extended 2 miles out into the ocean, as sea level was lower then, because of the glaciation. None of this is in question, thus global warming is real, and will not be accelerated or stopped by humanity.

Nothing in my post is in question, however the IPCC will just ignore all of it as though, it were unimportant. Is the glacier that has been melting for 20,000 years unimportant? Is the process that began the formation of that glacier unimportant? Global warming has been in effect for 20,000 years, this is important.

The article is just not based upon any fact.

I read another article that actually measured a 12 foot recede in a glacier in one year. The article proved this and said that this melt is unprecedented, then I did the math, and the 12 feet was some 40 miles in the past 20,000 years, when in reality this distance was over 900 miles, proving that the melt rate was higher in the past. Again this is all fact, Newsweek does not exist for facts, it exist to sell magazines, that are not being sold, because people are getting their news from the internet now.......

The recent warming caused by the artificial boosting of CO2 concentration in the earth's atmosphere has been kicking in for about 200 years. Not 20,000.

It's that accelerated warming, in defiance of all the "natural" factors and trends, overriding the normal responses and feedbacks of the planet's "natural" climate system, much faster than any climate change in geological history except for the ecological disasters (big meteor impacts, etc), that is the worrisome situation people refer to as "global warming".

20,000 years was the height of the last ice age, glaciers have been melting since then, but most people who comment on global warming have no clue of this as they do not understand that there was once a snowball Earth. As for CO2, no one even mentions CO2 anymore, because there has been no global warming for the last 18 or so years, and CO2 has been rising steadily in this timeframe.
 
Yes, many past ice ages, but this inter-glacial is different:

Opinions do not refute facts.
Methane, CH4 is mainly destroyed by the OH radical the harsh UV makes at high altitudes by splitting water H2O.
In all prior history the Sun's rate of production of the OH radical held the CH4 concentration low, but now CH4 is holding the OH radial concentration low. They destroy each other when they react. Thus the half life of CH4 is increasing at 0.3 years per year. I. e. in 2003 was measured to be 9.6 year but in 2013 that half life had increased to 12.6 years.
Again: Opinions do not refute facts.

Even at the current half life 1Kg of CH4 does more global warming than 100Kg of CO2 in the first decade after their release. The amount of releasable CH4 holds more carbon than exists in all the coal on earth. I.e. for practical purposes*, there is no limit on how high the CH4 concentration can climb.

* Mankind will be extinct before that limit is reached.

Prove me wrong?

I dare you?

maybe you should step up a level from primitive data. try stepping into other elements that are involved. i notice you do not have a grasp of what all is involved.

You being ignorate of the literature does not make your false assertion true:
http://cdiac.ornl.gov/trends/atm_meth/ice_core_methane.html said:
This page introduces ice-core records of methane (CH4) extending back 800,000 years at Dome C, Antarctica and over 400,000 years at the Vostok site. Links are also provided to shorter records from other Antarctic locations. The 2000-year record from Law Dome, Antarctica, has been merged with modern records to create a long-term record to the present.
These records are maintained by the World Data Center for Paleoclimatology, National Oceanic and Atmospheric Administration (NOAA), and have graciously been made freely available for access and distribution. The original investigators made the effort to obtain the data and assure their quality.

These are the locations where many different investigators collected ice core bubble data.
I. e gas chromatography is MEASUREMENTS, NOT "HUMAN INTERPRETATION"
The US's EPA gives my graphs too. See: http://www.epa.gov/climatechange/science/indicators/ghg/ghg-concentrations.html

If you search you can find same data and other measurements by several other government's research teams and collaborating data from soil samples and shells.

Especially true is: IGNORANT, UNINFORMED, OPINION DOES NOT REFUTE FACTS.

Ah, NASA has confirmed the highest amount of sea ice around Antarctica, than at any time in recorded history. This is a fact, that is not refutable. ...

Agreed. The AREA of Antarctic floating sea ice is increasing because the previously stable and "plugged" flow from glacier (land ice) is accelerating into the sea, I showed earlier (in post 23)* a photo of that happing in the East Antarctic Shelf that was believed to be a stable plug blocking the glacier behind its flow into the sea. More floating sea ice is a cause for increased concern - not a good sign.

* Here is link to post 23: http://www.sciforums.com/threads/is-global-warming-even-real.143423/page-2#post-3255435 as photo is large and don't want to post again.

cute :). yes, it's usually the low level minded individuals that resort to grammar policing.
that still does not address your acknowledgement of the whole subject that you lack. that just shows you cannot move forward in this conversation, because you may not understand what i'm referring to as you spew from some primitive media driven, elementary nonsense.
it's that simple.

Actually, the increased sea ice

The fact, is that the current warming trend, has been in effect since the height of the last ice age, which was some 20,000 years ago. You may claim that this ice age never happened, or that the ice has not been melting for the last 20,000 years, but this would be quite unscientific. In fact, Canada would not even exist if not for global warming, so for Canadians at least the warming is a very good thing.
