The real issue that the fossil fuel industry propagandists want everybody to ignore is the fact that the Earth's oceans are absorbing over 90% of the extra heat that the increased carbon dioxide in the atmosphere is retaining. The Earth has not stopped warming...just the opposite actually...global warming has, in fact, been still accelerating. The oceans have always been absorbing most of the excess heat the elevated CO2 has been retaining but in the last decade or so, even more of the excess heat has gone into the oceans than has gone into the atmosphere due to prolonged and repeated La Nina events in the Pacific that pull colder water to the surface and transfer warmer water to the ocean depths.
Here is an excellent article, written by one of the foremost climate scientists and published on one of the premier science based climate info websites that is written by actual climate scientists, describing what is happening now.
What ocean heating reveals about global warming

The heat content of the oceans is growing and growing. That means that the greenhouse effect has not taken a pause and the cold sun is not noticeably slowing global warming. NOAA posts regularly updated measurements of the amount of heat stored in the bulk of the oceans. For the upper 2000 m (deeper than that not much happens) it looks like this:

The amount of heat stored in the oceans is one of the most important diagnostics for global warming, because about 90% of the additional heat is stored there (you can read more about this in the last IPCC report from 2007). The atmosphere stores only about 2% because of its small heat capacity. The surface (including the continental ice masses) can only absorb heat slowly because it is a poor heat conductor. Thus, heat absorbed by the oceans accounts for almost all of the planet’s radiative imbalance. If the oceans are warming up, this implies that the Earth must absorb more solar energy than it emits longwave radiation into space. This is the only possible heat source. That’s simply the first law of thermodynamics, conservation of energy. This conservation law is why physicists are so interested in looking at the energy balance of anything. Because we understand the energy balance of our Earth, we also know that global warming is caused by greenhouse gases – which have caused the largest imbalance in the radiative energy budget over the last century. If the greenhouse effect (that checks the exit of longwave radiation from Earth into space) or the amount of absorbed sunlight diminished, one would see a slowing in the heat uptake of the oceans. The measurements show that this is not the case. The increase in the amount of heat in the oceans amounts to 17 x 1022 Joules over the last 30 years. The data in the graphs comes from the World Ocean Database. The data set includes nine million measured temperature profiles from all of the world’s oceans.
