The Path to Global Warming

<jats:p>--</jats:p>


Introduction
One would like to know when the outcomes of global warming become truly horrific. If it is the case that climate change is unstoppable (Hawking irreversibility), then when will this be undeniably visible?
Several ecological disasters occur new weekly around the globe. Are they due to rising temperatures?
Ecologists speak of a gigantic crisis for Planet Earth with the extinction of many species, True? Gould global warming be indirectly the cause of many disasters?
In Table 1 the relationship between energy consumption and temperature rise is modelled. Energy consumption is near 16 billion with + 1 degree. Looking at stylised projections, we will move towards 24 billion with + 2 degrees. That would create lots of difficult problems for mankind. between socio-economic development on the one hand and increasing CO2 demand on the other hand.
The two horns of this global dilemma are poverty reduction and CO2 increased where both outcomes are driven by economic growth. It is urgent to invent how development can be promoted by carbon neutral economic growth. Development can be carbon neutral. The relationship between energy and global economic output can be modeled as follows: The Cambridge Dictionary lists two meanings of "sustainable"; able to continue over the period of time firstly, and secondly causing no or little damage to the environment. Taking together these two concepts fit well into the environmental framework, but they do not apply to the demand and supply of energy.
Here we need a second equation, namely: (II) y: CO2 concentration in ppm, x= Energy in Billion tonnes of oil equivalent.

Figure 2. Energy Consumption-CO2 Concentration c) TEMPERATURE
The yearly rises in average global temperature are welł documented. The link between atmospheric concentration and temperature increase is shown in Figure 3.   (6) Increase by 1 ppm CO2 leads to increase in global temperature 0,01 degrees CO2 concentration has grown from 315 to 410 so temperature has risen with c:a 1 degree as figure shows.
A spurious correlation ? Self-evident? No. Probably not, as it reflects the rising dependence on energy from fossil fuels. The fossil fuels are in much demand, because they offer cheap energy which is vital for affluence. Is the planet already at its Hawking irreversibility? The notion of irreversible transformation is very menacing, as policy could only slow down the arrival of a global disaster There is a way to find out about irreversibility, namely to consult the global thermometer CO2 daily: 28/12 at 412 ppm and 408 one year ago (CO2).
Following the logic of the model on (1), one cannot but arrive at a sinister future for mankind. At levels of CO2 over 450 ppm the negative outcomes of global warming will be much stronger. The best way to counteract is simply to close all coal plants right now.

Conclusion
Below we make an attempt to calculate how much solar energy would be required to replace coal power. As benchmark the Bhadla Solar Park in India is used, projected to deliver 2255 MW once construction is ready from December 2019. In all, 900 such plants would be necessary to completely eliminate all coal power generated in 2018. Table 2 illustrates how many solar plants of this size each of the ten biggest coal producing nations would need to install to replace their entire coal power production.  Germany 32
