also, if Global Warming means things are also gonna get colder, how do we know that this isn't just a natural cycle?

I mean if we are talking Global temperatures, we have in fact had much warmer global temperatures in the past, and that was before cars, hairspray, and whatever else gets blamed on human causes.
In fact if we are talking Global temperature, Global Warming isn't even happening right now. From the beginning of 1997 until August 2012 there was no discernible rise in aggregate global temperatures. This means that the ‘pause’in global warming has now lasted for about the same time as the previous period when temperatures rose, 1980 to 1996.

We are also at a 600 million year low as far as CO2 levels.

The leveling off of temps over the last 15 years does give reason for skepticism.

However, the melting of ice, and the evaporation of water results in a cooling process. The heat is "hidden" and is known as latent heat. This and other phenomana of the sort(check out something called gaia) could be at play in keeping temperatures, for the time being at least, from raising in a direct correlation with the CO2.

It should also be noted that, though we have seen a leveling off, every year since 1997 is amongst the warmest since temps have been recorded. Every year has been near record temp, and 2012 is thought to be the warmest yet(don't think data it out on that yet, but should be soon).

The 600 million years things only means something if CO2 levels does not always correlate to temperature. Graphs I've seen pretty much always put the 2 in unison(as the video u posted did).

1)A cycle is overall warming, and then overall cooling. But what we are now seeing is merely overall warming. And this overall warming is factoring in isolated areas of cooling. As I said before global warming theory never suggested even warming throughout the world. The cooling areas are a paradox when looking at the issue from a far. But once u look deeper into the science, the isolated cooling is not unexpected given the overall warming. See inconveniant truth for examples.

2) Sure we have been warmer in the past. And something caused that warming. But what does that have to do with human CO2 emissions now causing warming? If anything cause and effect cycles of the past further back the cause and effect expectations of global warming theory.

Well easterman's pdo theory, as well as the low sun spot activity may be part of the reason for the current temperature plateau. Temporarily offsetting the effects of increased CO2 in the atmosphere. Probably lucky that we are experiencing these phases.

But Global cooling? That certainly did not happen in this past decade.

And 2012 was by far the warmest we have seen in the contiguous US.

however this will not be the warmest globally.

"Even so, the last year’s U.S. record is not expected to translate into a global temperature record when figures are released in coming weeks. The year featured a La Nina weather pattern, which tends to cool the global climate overall, and scientists expect it to be the world’s eighth- or ninth-warmest year on record."

10th warmest on record.

Warmest La Nina year on record.

From the report:

Including 2012, all 12 years to date in the 21st century (2001–2012) rank among the 14 warmest in the 133-year period of record. Only one year during the 20st century—1998—was warmer than 2012.

against the overall trend:

Meanwhile, most of Alaska, far western Canada, central Asia, parts of the eastern and equatorial Pacific, southern Atlantic, and parts of the Southern Ocean were notably cooler than average.
Additionally, the Arctic experienced a record-breaking ice melt season while the Antarctic ice extent was above average.

The 2012 temperature across the United Kingdom was 0.1°C (0.2°F) below the 1981–2010 average. This is in part attributed to the UK's coolest summer since 1998 and coolest autumn since 1993.

Ice and Snow coverage is a series of conflicting results.

For all of 2012, Arctic sea ice extent was below average.

On March 18th, Arctic sea ice reached its annual maximum extent at 5.88 million square miles (15.24 million square km)—0.24 million square miles (0.61 million square km) below average—which began the annual melt season.

The annual Arctic sea ice melting ended on September 16th, when the Arctic sea ice extent dropped to 1.32 million square miles (3.41 million square km), the lowest value ever recorded. The annual minimum extent was 49 percent below average and 0.29 million square miles (0.76 million square km) below the previous smallest extent which occurred in September 2007.

Between March 18th and September 16th, 4.57 million square miles (11.83 million square km) of ice melted—the largest ice loss of any melt season on record. Arctic sea ice during September has been lost at an average rate of 13.0 percent per decade.

Antarctic sea ice extent was above average for most of 2012. Sea ice in the Southern Hemisphere peaked on September 26th, reaching its annual maximum extent, at 7.51 million square miles (19.44 million square km). This was the largest Antarctic sea ice extent on record, surpassing the previous record of 7.47 million square miles (19.36 million square km) which occurred in September 2006. Antarctic sea ice during September has increased at an average rate of 0.9 percent per decade.

Winter (December 2011–February 2012) snow cover extent for the Northern Hemisphere was 228,000 square miles (590,000 square km) above average, making it the 14th largest seasonal snow cover extent on record. North American snow cover was below average during the season, or fourth smallest winter extent on record, while Eurasian snow cover ranked as its fourth largest on record. Spring snow cover extent for the Northern Hemisphere was much below average and ranked as the sixth smallest on record. Both North America and Eurasia had below-average spring snow cover.

The Northern Hemisphere snow cover extent in December 2012 was the largest on record at 1.2 million square miles (3.0 million square km) above average and (0.08 million square miles (0.2 million square km) above the previous record from 1985. Both North America (13th largest) and Eurasia (second largest) had above-average December snow cover.

Winter Northern Hemisphere snow cover has expended at an approximate rate of 0.1 percent per decade, while spring Northern Hemisphere snow cover has shrunk at an approximate rate of 2.2 percent per decade.
