The regulator at work are the massive oceans. When you figure the amount of energy necessary to raise the oceans by 1 degree, you will quickly see why the ocean serve as a regulator, and the crap model of exponential changes are wrong. This is not complicated here Icey. Figure out the amount of energy required to raise the temps of the oceans. Then figure out what occurs when you do and evaporation sucks out some of that energy. Water is amazing. It not only grants of life, but it makes our climate extremely stable even after all the other factors that attempt to change it, including meteor strikes. This is why life has survived on Earth for more than a billion years. Its not some big mystery or state secret here. Its that stuff that covers 71% of the Earth's surface.
Edit:
Icey,
Concluding a cause, when the CO2 drops follow the temp drops??? LOL.
The climate system evolves in time under the influence of its own internal dynamics and due to changes in external factors that affect climate (called ‘forcings’). External forcings include natural phenomena such as volcanic eruptions and solar variations, as well as human-induced changes in atmospheric composition. Solar radiation powers the climate system.
There are three fundamental ways to change the radiation balance of the Earth:
by changing the incoming solar radiation (e.g., by changes in Earth’s orbit or in the Sun itself);
by changing the fraction of solar radiation that is reflected (called ‘albedo’; e.g., by changes in cloud cover, atmospheric particles or vegetation);
by altering the longwave radiation from Earth back towards space (e.g., by changing greenhouse gas concentrations).
Climate, in turn, responds directly to such changes, as well as indirectly, through a variety of feedback mechanisms.
Wikipedia is your friend.
The recent phenomenon of Global warming has been attributed primarily to increasing atmospheric carbon dioxide concentrations in Earth's atmosphere. Since the Industrial Revolution, the concentration of carbon dioxide has increased markedly from 280ppm to 395 ppm as of 2013, with the increase largely attributed to anthropogenic sources, particularly the burning of fossil fuels.[3] The daily average at Mauna Loa first exceeded 400 ppm on 10 May 2013. It is currently rising at a rate of approximately 2 ppm/year and accelerating. An estimated 30–40% of the carbon dioxide released by humans into the atmosphere dissolves into oceans, rivers and lakes. which contributes to ocean acidification. The present level of CO2 is the highest in the past 800,000 years[9] and likely the highest in the past 20 million years. Although carbon dioxide levels have varied significantly over the course of Earth's 4.7 billion year geologic history and ancient-earth biospheres, the scientific consensus is that the present-day biosphere can be damaged if CO2 levels surpass 550 parts per million. [1]
P.S. The video's Maxx posted have been debunked by the very scientist featured in them. [2]
Yes we are adding CO2 to the atmosphere, but CO2 has only a small warming effect ( we had an ice age in the ordovician period when CO2 was 10x higher) natural factors such as ocean currents and solar changes are having a bigger effect.
Okay Antarctic ice I will answer it, the faint young sun paradox, why was Earth not a giant snowball, back when solar energy was less, well there are many theories but nobody really knows, what is remarkable is throughout all the changes, solar output, planets orbital changes, asteroid strikes, shifting continents, volcanic activity, our climate has stayed fairly stable, it's almost as if there is a regulator at work.
The various factors that change with solar cycles,
1 the solar magnetic AP index, when this went very low in 2009 the mesosphere shrank

2 Total solar radiation may only change by 0.1 % but some factors like extra ultra violet, change quite a lot up to 6%
3 cosmic rays ramp up quite a bit during quiet solar periods, this has an affect on cloud seeding.
4 the solar wind changes quite a bit too.
exactly what the effects of these changes is a bit of an unknown quantity but it is being closely studied and we should know more after this cycle.
What is known is that the little ice age coincided with a long period of zero sunspots

People.
It's not just one thing we have done, but many: we have built urban heat islands, cut down forests, changed the landscape from prairies to farmland, added gases like CO2 to the atmosphere, etc.
EDIT: Oops, Sagebrush just admitted that people influence climate--guess you didn't think that one through, did you?
Another EDIT: Raisin Caine ignores that it is the combined surface temperature that has gone up--atmosphere AND oceans. He also implies that you have to raise the temperature of the ENTIRE ocean. This is ridiculous, we humans live near the surface of the planet, and if stays near freezing down near the bottom of the ocean, it's not going to matter too much to our weather. He makes many assertions without ever backing ANY of them up,and yet he is completely out of his field. If he has proof for anything he says, he should really switch fields and start publishing in atmospheric science and climate, but I'm not holding my breath waiting for that to happen.
You are doing school work I think. And your teacher is looking for the answer that mankind is now burning so called fossil fuels. So you can give him that answer... but in reality this has no effect. Man-made Global Warming is a HOAX.
It's been cooling for at least 12 years.

Top climate scientists say there is no man-made Global Warming.
The Great Global Warming Swindle
CO2 is known to have been a moderate to major contributor to past natural climate change, with the source usually being volcanoes and either a very large eruption or a quite long time for the CO2 to build up.
Just in the last few days denier have tried to use the Jurassic period to say CO2 is good "we had lush plants when levels where 2200ppm" of course they neglect to mention that also during this period we had no ice caps and much higher sea levels.
James plays a similar game of course we have a new influence 'us' we are responsible for ~40% increase in CO2 over the last 100 years and to a larger degree the last 50 years. Going from a pre-industrial level of 280ppm to the current level of 397ppm, the highest CO2 has been in more than 800,000 years, the current projections have levels reaching 650-700ppm by the end of the century, this is more than a third of the way to those Jurassic levels of 145 million years ago, we know the increase in not volcanic as we have the isotope ratios that show the extra CO2 is not of volcanic origin.
Basically the denier claim seems to be it's all a coincidence that CO2 rose at the exact same time we started to burn fuels that produce large volumes of CO2 as a byproduct of burning them. In comparison to volcanoes we currently produce 100x the CO2 that our current level of volcanic activity is.
http://hvo.wr.usgs.gov/volcanowatch/arch...
As if they are trying to produce comedy, deniers have tried to claim current CO2 was caused by volcanoes, yet they try to ignore what past volcanic activity may have done, past activity that was far larger than anything we see at the moment.
On kano's, Ordovician point or is that pointless
He is talking of a period 485 million years ago, the mean CO2 level for the period was 4200ppm which I asume is what kano is basing the comment on, but note he makes no mention of temperatures it was in the early Ordovician, very warm with high sea levels.
http://en.wikipedia.org/wiki/Ordovician#...
later it cooled because, wait for it!, CO2 dropped in the late Ordovician, and it only then that glaciers form, this happened because the high CO2 was coming from significant volcanic activity and that was balanced by weathering as on land life had still barley taken hold and most of the exposed ground of the planet was still exposed, later plants would cover this in soil and weathering would be reduced by a more cyclic process.
http://geology.gsapubs.org/content/37/10...
Toward the end of the Ordovician this process was interrupted by a reduction in volcanic activity, while the weathering continued and temps dropped glaciers formed and sea level dropped. Given that deniers want to go back this far it should also be said that half a billion years ago the Sun was also putting out ~5% less energy than it does today. Now our denier friend could say this is nothing but given this same denier has claimed climate change linked to the current very short dip in solar activity in the low cycle of the 11 year solar cycle, which is a drop of less than 0.1% for only about 1 year compared to the many million of years at 5% less, if he attempts to try and make excuses for this, it should be quite funny to read.
Barack Obama, with the assistance of all other greenies.
nothing new. same old factors that have been around for 100s of millions of years.
Help me....help...what's answer!?
