Well...er...be happy, unless the long-term global temperature deceleration continues into a miserable and dangerous global cooling situation...as the GISS (NASA) empirical evidence indicates, CO2-caused "catastrophic" global warming is an absolute non-issue..... (click on below chart to enlarge)
What happens when one plots the GISS global temperature and CO2 trends for the long-term periods ending September 30, 1999 and September 30, 2014?
Yes, one gets the above two charts, revealing interesting, empirical climate science truths, such as:
1. The chart on the left (for periods ending Sept. 1999) reveals an acceleration of global warming trends, while the CO2 growth trends (see black dotted curve) across periods were fairly stable.
2. The chart on the right (for periods ending Sept. 2014) reveals a deceleration of global temperature change that over the 'last 10 years' reached a very slight global cooling status; yet, as can be seen, the CO2 growth trend was accelerating, reaching a rate robustly greater than those periods ending in 1999.
3. Other than a single datapoint (blue column), all the long-term temperature trends for the left chart exhibit warming greater than 1.5 degrees per century; in contrast, the majority of trends (blue columns) for the right chart are below 1.5 degree per century, despite faster CO2 growth and the associated higher atmospheric CO2 levels.
4. Rapid, dangerous, scary, undeniable, indisputable, irreversible, accelerating and catastrophic global warming claims made by various politicians, scientists, bureaucrats, celebrities and "journalists" are unequivocal lies. Long-term global temperature trends below 2 degrees (and going lower) are clearly the opposite of those widely-used, deceptive descriptors.
5. If it was not obvious before, CO2 is not a global "control knob" nor some type of "planet thermostat" - CO2 does not have much, if any, influence on temperature trends.
6. Confirming what climate skeptics (often called "deniers" for denigration purposes) have been stating for the last several decades, the climate changes constantly, primarily from natural forces. As a result, global temperature trends change frequently, exhibiting both cooling and warming modes across time spans.
We call it 'natural' climate change and ancient and historical climate records are replete with it. It happens often and, my goodness, it can be really extreme.
Now some caveats. The charts display a wide variety of temperature trends - they are not predictions for the future. They represent a snapshot in time and can change quickly.
One cannot conclude from the right chart that global temperatures will continue to decelerate into a glacial freezer. That would be exactly the same mistake that the climate "experts" made with the chart on the left - concluding that the temperature trends would just keep accelerating until hellish warmth would end-civilization-as-we-know-it.
And, these two charts cannot be used to claim that humans have no influence on global temperatures. Besides emissions of greenhouse gases, humans are constantly changing their environment which does have an impact (e.g. turning a corn field into an asphalt parking lot or massive deforestation in the world's major tropical rainforests or laying down a carpet of black soot on ice sheets).
Putting aside any further caveats, as an added bonus, the charts can be used to identify climate-liars. These are personalities and organizations that would never publish temperature charts as seen here. Instead, they resort to visual or verbal representations that today, or this month, or this year was the 'warmest' ever. This is not only the worst kind of cherry-picking, it is also incredibly lame.
Since the Little Ice Age (LIA), the world has been warming. It will continue to do so. Thus, we are going to keep experiencing warm(er) and warm(est) events - it's a no-brainer due to natural warming rebound. It will only stop happening when the world enters another mini ice age or worse. Those are the stubborn facts, which essentially makes CO2's trivial influence irrelevant.
When one hears the 'warmest' or 'warmer' refrains, that is when it becomes apparent one is in the company of a climate deception-meister.
Finally, let's all hope the global temperature deceleration shown on the right-most chart stops before it gets really ugly.

Note: Temperature dataset and CO2 dataset used to produce Excel charts and 2nd order fitted trend of the trends. Excel's slope function was used to caluclate each period's trend, then multipled by 1200 to produce a per century trend. Hey, don't know how to chart in Excel? It's easy to produce charts - you can do it too! Go here to learn how.
