Certainly, we could stop global warming. Just reduce anthropogenic greenhouse gas emissions to levels below what nature can sequester. In about a half-century, the global mean near surface temperatures will stop rising.
I'm inclined to agree with your comment about overpopulation - 7 billion humans, all demanding heat and light and transport and food, half of whom live in cities (which are the very definition of unsustainability)... and 'renewables' are nowhere near up to the job of substituting for fossil fuels, so there's not much chance of stopping global warming any time soon. The evidence shows that even a total cessation of greenhouse gas emissions (which isn't going to happen) would probably barely bring global warming to a halt, and that's assuming we haven't kicked off enough natural positive feedbacks by then to take the warming out of our control.

I doubt we can do much to influence it and question if we should even try. I don't believe in the global, Carbon Credit scheme that is designed to make some people a lot of money and achieve ZERO!
Because the natural cycle at this point in time, due to orbital cycles, is a long slow cooling trend towards the next glaciation in a few thousand years. Instead, we've caused an extremely rapid warming trend.
The Earth goes through heating and cooling periods. We are in the near beginning of the heating period; has to do with sun-spots. Also, the idea that an increase of CO2 emissions are somehow responsible for "Global Warming" is just incredibly false. See the video for an experiment with plants and concentrations of CO2.
The current extremely rapid global warming isn't natural. Without human influences the world would have continued cooling. Look at the temperature evolution of the Arctic:
The extremely rapid warming of the last ~200 years is due to our enormous greenhouse gas emissions - we've turned a natural long slow cooling trend into a warming trend 100 times as fast. It's much faster than anything in the geological record. The sun certainly isn't responsible for it - we've had the same warming effect in just 250 years as the sun took 125 million years to achieve.
They aren't. The sun has been cooling for decades as any solar physicist will tell you, for example:
"We have previously placed the solar contribution to recent global warming in context using observations and without recourse to climate models. It was shown that all solar forcings of climate have declined since 1987 . The present paper extends that analysis to include the effects of the various time constants with which the Earth's climate system might react to solar forcing. The solar input waveform over the past 100 years is defined using observed and inferred galactic cosmic ray fluxes, valid for either a direct effect of cosmic rays on climate or an effect via their known correlation with total solar irradiance (TSI), or for a combination of the two. ... The conclusions of our previous paper, that solar forcing has declined over the past 20 years while surface air temperatures have continued to rise, are shown to apply for the full range of potential time constants for the climate response to the variations in the solar forcings." Recent oppositely directed trends in solar climate forcings and the global mean surface air temperature. II.

So with this in mind, please explain how the Earth is warming so fast (much faster than any known period in the geological record) despite both the sun being on a cooling trend and the orbital cycles also contributing a cooling effect.
Can you do that, without including the massive warming effect of anthropogenic greenhouse gases?
Yet the Yearly mean global CO2 levels keep rising.
the direct measurement of greenhouse forcing:
Carbon Dioxide, or CO2, and Methane, or CH4, each have different infrared spectra. Satellites recording the infrared spectra of our planet's atmosphere can tell how much infrared energy each gas in our atmosphere traps. The fraction of Earth's greenhouse effect from CO2, CH4, and many other gases is therefore directly measurable. These measurements have been taken for more than three decades, now. Please see:
