Fine, then give a credible hypothesis that explains the current changes?
Natural variability...ice core, and numerous other proxy study have shown temperature changes happening which are far greater in magnitude than any change we have seen and those changes have happened more quickly than any change we have seen.
We KNOW that humans have dramatically have increased the rate of which this gas is released in the atmosphere.
Actually, we know no such thing. Here are seven peer reviewed, published studies which show very clearly that our effect on the total atmospheric CO2 is largely unmeasurable.. human beings, with all our CO2 producing capacity don't even make enough CO2 to overcome the year to year variation in the earth's own CO2 making machinery...
The fact is that the amount of CO2 we produce from year to year does not track with the amount of increase in atmospheric CO2.

CLIP: “A necessary condition for the theory of anthropogenic global warming is that there should be a close correlation between annual fluctuations of atmospheric CO2 and the annual rate of anthropogenic CO2 emissions. Data on atmospheric CO2 and anthropogenic emissions provided by the Mauna Loa measuring station and the CDIAC in the period 1959-2011 were studied using detrended correlation analysis to determine whether, net of their common long term upward trends, the rate of change in atmospheric CO2 is responsive to the rate of anthropogenic emissions in a shorter time scale from year to year. … [R]esults do not indicate a measurable year to year effect of annual anthropogenic emissions on the annual rate of CO2 accumulation in the atmosphere.”

If you look at the graph...assuming that you can read a graph...you will see for example, that there was a rise in our emissions between 2007 and 2008 but a significant decline in the atmospheric CO2 concentration. Do you believe that human CO2 went somewhere to hide and waited around for some years before it decided to have an effect on the total atmospheric CO2 concentration? Then between 2008 and 2009, there was a decline in the amount of CO2 that humans emitted into the atmosphere, but a significant rise in the atmospheric CO2 concentration. Then from 2010 to 2014 there was a large rise in man made CO2 emissions but an overall flat to declining trend in the atmospheric CO2 concentration. Between 2014 to 2016 there was a slight decline in man made CO2 emissions, but a pronounced rise in the atmospheric CO2 concentrations. Like I said, we produce just a fraction of the natural variation in the earth's own CO2 making machinery from year to year and we are learning that we really don't even have a handle on how much CO2 the earth is producing...the undersea volcanoes are a prime example of how much we don't know.

CLIP: “The recent increase of the CO2-content of air varies distinctly from year to year, rather independent from the irregular annual increase of global CO2-production from fossil fuel and cement, which has since 1973 decreased from about 4.5 percent to 2.25 percent per year (Rotty 1981).”
“Comparative investigations (Keeling and Bacastow 1977, Newll et al. 1978, Angell 1981) found a positive correlation between the rate of increase of atmospheric CO2 and the fluctuations of sea surface temperature (SST) in the equatorial Pacific, which are caused by rather abrupt changes between upwelling cool water and downwelling warm water (“El Niño”) in the eastern equatorial Pacific. Indeed the cool upwelling water is not only rich in (anorganic) CO2 but also in nutrients and organisms. (algae) which consume much atmospheric CO2 in organic form, thus reducing the increase in atmospehreic CO2. Conversely the warm water of tropical oceans, with SST near 27°C, is barren, thus leading to a reduction of CO2 uptake by the ocean and greater increase of the CO2. … A crude estimate of these differences is demonstrated by the fact that during the period 1958-1974, the average CO2-increase within five selective years with prevailing cool water only 0.57 ppm/a [per year], while during five years with prevailing warm water it was 1.11 ppm/a. Thus in a a warm water year, more than one Gt (1015 g) carbon is additionally injected into the atmosphere, in comparison to a cold water year.”
Practically every actual study ever done tells us that increases in CO2 follow increases in temperature...that means that increased CO2 is the result of increased temperature, not the cause of increased temperature...which makes sense since warm oceans hold less CO2 and as they warm, they outages CO2.

“There exist a clear phase relationship between changes of atmospheric CO2 and the different global temperature records, whether representing sea surface temperature, surface air temperature, or lower troposphere temperature, with changes in the amount of atmospheric CO2 always lagging behind corresponding changes in temperature.”
(1) The overall global temperature change sequence of events appears to be from 1) the ocean surface to 2) the land surface to 3) the lower troposphere.
(2) Changes in global atmospheric CO2 are lagging about 11–12 months behind changes in global sea surface temperature.
(3) Changes in global atmospheric CO2 are lagging 9.5–10 months behind changes in global air surface temperature.
(4) Changes in global atmospheric CO2 are lagging about 9 months behind changes in global lower troposphere temperature.
(5) Changes in ocean temperatures appear to explain a substantial part of the observed changes in atmospheric CO2 since January 1980.
(6) CO2 released from anthropogenic sources apparently has little influence on the observed changes in atmospheric CO2, and changes in atmospheric CO2 are not tracking changes in human emissions.
(7) On the time scale investigated, the overriding effect of large volcanic eruptions appears to be a reduction of atmospheric CO2, presumably due to the dominance of associated cooling effects from clouds associated with volcanic gases/aerosols and volcanic debris.
(8) Since at least 1980 changes in global temperature, and presumably especially southern ocean temperature, appear to represent a major control on changes in atmospheric CO2.

CLIP: “[T]he warming and cooling of the ocean waters control how much CO2 is exchanged with atmosphere and thereby controlling the concentration of atmospheric CO2. It is obvious that when the oceans are cooled, in this case due to volcanic eruptions or La Niña events, they release less CO2 and when it was an extremely warm year, due to an El Niño, the oceans release more CO2. [D]uring the measured time 1979 to 2006 there has been a continued natural increase in temperature causing a continued increase of CO2 released into the atmosphere. This implies that temperature variations caused by El Niños, La Niñas, volcanic eruptions, varying cloud formations and ultimately the varying solar irradiation control the amount of CO2 which is leaving or being absorbed by the oceans.”

CLIP: “[With the short (5−15 year) RT [residence time] results shown to be in quasi-equilibrium, this then supports the (independently based) conclusion that the long-term (∼100 year) rising atmospheric CO2 concentration is not from anthropogenic sources but, in accordance with conclusions from other studies, is most likely the outcome of the rising atmospheric temperature, which is due to other natural factors. This further supports the conclusion that global warming is not anthropogenically driven as an outcome of combustion.”

“[T]he trend in the airborne fraction [ratio of CO2 accumulating in the atmosphere to the CO2 flux into the atmosphere due to human activity] since 1850 has been 0.7 ± 1.4% per decade, i.e. close to and not significantly different from zero. The analysis further shows that the statistical model of a constant airborne fraction agrees best with the available data if emissions from land use change are scaled down to 82% or less of their original estimates. Despite the predictions of coupled climate-carbon cycle models, no trend in the airborne fraction can be found.”
Like it or not, that last sentence means that there simply is not a discernible trend in the percentage of atmospheric CO2 that can be linked to our emissions...that is because in the grand scheme of things, the amount of CO2 that we produce is very small...not even enough to have any measurable effect on the year to year variation of the earth's own CO2 making processes...
Here is a paper from James Hansen himself...the father of global warming and the high priest of anthropogenic climate change...

CLIP: “However, it is the dependence of the airborne fraction on fossil fuel emission rate that makes the post-2000 downturn of the airborne fraction particularly striking. The change of emission rate in 2000 from 1.5% yr-1 [1960-2000] to 3.1% yr-1 [2000-2011], other things being equal, would [should] have caused a sharp increase of the airborne fraction”

We know the earth is warming. What's the unknown here in your opinion?
The fact is that the pause is real and has been going on for about 2 decades now...the surface record is heavily homogenized, infilled, and manipulated in order to claim a warmest temperature ever by a hundredth of a degree...on average, there is one temperature data station for every 10,000 square miles or so.....what do you think the "average" temperature really means on a planet on which the maximum and minimum temperature on any given day spans 200 degrees?
And the unknown are so great that we really don't even know where to start...For example, the TSI of the sun is relatively constant...but the output in any particular wavelength varies wildly from day to day, month to month, year to year, century to century...what effect does each particular wavelength have on our climate...and how do changes in particular wavelengths alter our climate...The fact is that we are just beginning to scratch the surface in regard to what we know about our climate and what drives it..
And do note that I am not trying to pass of 20 year old studies as if they mean something today...
