The world could get colder over the next two decades - but still hotter in the long run, expert predicts

I'm pretty confident that in the long run it will be colder at some points and hotter at some points. I don't believe we happen to currently be at one of the extremes.

is insignficant to the global temperature, and no matter what we did with increasing or decreasing it, there would be no effect on the actual temperature of the globe.

Here's the real story.
Water vapor is the controlling factor by miles.

Global air temperatures have been rising at a steady trend rate of 0.5°C per century since about 1750, as the world recovers from the little ice age:

On top of that trend are oscillations that last about 30 years in each direction:

1882 – 1910 Cooling
1910 – 1944 Warming
1944 – 1975 Cooling
1975 – 2001 Warming

The long-term trend suggests that the last warming period (1975-2001) was like the previous one (1910-1944), and that once the effects of the little ice age have finally passed, the temperature will get back to where it was in the medieval warm period (which is also where it was during the Roman Optimum, and in the Holocene optimum before that).

What about human influence? Human emissions of CO2 were virtually non-existent before 1850, and were insignificant compared to current levels until after 1945.

It is worth bearing in mind that there is no actual evidence that carbon dioxide was the main cause of recent warming—it’s only an assumption, and the calculations of future temperature rises derive most of their warming from an assumed water vapor feedback for which there is only counter-evidence.

If you analyze the sunspot numbers statistically to identify all the cycles that test to be significant you will find multiple cycles, the well known 11 year cycle being just one of the many you can identify.

If you measure and then project each of these cycles into the future and add them together to see the net effect, the results show that during the second half of this century we will have a period of low activity; low sunspot activity is associated with cold climate on earth.

The severity of the predicted minimum for the second half of this century is not as low as the Maunder Minimum of the 1600's, but lower than the Dalton Minimum of the early 1800's. Using this modeling technique, the first half of this century should be more or less average.

So who really knows about the future!

First of all, the weather cannot be reliably predicted. The "meteorologists" cannot predict whether or not it's going to rain TOMORROW let alone next year or 20 years from now. Anyone with even a basic understanding of math and differential equations knows this weather prediction nonsense is 100% bunk. The derived predictive formulas are so incredibly sensitive to the initial conditions the entire hypothesis (either way: hot or cold) can be easily rejected immediately. Whenever you see "top climate modeler" just think "dice roller" and you'd be just as correct.
