CO2 Sequestration [CO2 Emission & Absorption]
Feasible to precisely estimate the annual production of CO2 from human activity? What happens when it exceeds 10^14 kg?
How far the global CO2 emissions from fossil fuels and industry is expected to grow from its current value of nearly 40 billion metric tons (GtCO2)? And, when could (year) we expect the point of inflection?
From the current values of CO2 emissions by Coal (16 billion tons), Oil (12 billion tons) and Gas (8 billion tons), how much do we expect to get reduced by 2030, 2040 & 2050?
From the current values of CO2-emitting sectors by Electricity and heat production (50%); Transport (25%); & Manufacturing & construction industries (20%), how much changes do we expect by 2030, 2040 & 2050?
Why were the global CO2 emissions - mainly unchanged - between 2014 & 2016?
What happens when we fail to stabilize CO2 emissions despite our focus on energy conservation, energy efficiency or fuel substitution and alternative sources of energy (apart from the occurrences of heat-waves & extreme-events of rainfall – which is quite a normal physical phenomena, associated with the conventional earth’s climate change that gets repeated over geological-cycle)?
OR
With the current world average temperature hanging around 15.031 deg C; and with world average temperature of 0.018927 deg C in 2024, and with the weekly (in July 2024) world average temperature of 0.000627 deg C, what exactly it means, even, if we end up exceeding 4+ deg C increase by 2100 as against the aim of Paris Agreement to keep the rise of global temperatures to 2 deg C in this century?
With nearly 3 million hectares of forests cut down per month globally, whether, deforestation remains to be the major culprit between the imbalance between the emission from soil (525 billion tons of CO2 per annum) and the absorption in the forest (485 billion tons of CO2 per annum)?

Obvious, humans as a species, are unable to wean itself from fossil fuels quickly enough... to make any impact on Global Warming.
Also, countries are unwilling to shut down antiquated and useless sections of their economies, like investing in war making and standing armies, to transfer those funds to fight humanity's four greatest enemies-- Global Warming, Desertification, Meeting basic human needs, and Providing free health care and education.
The only reasonable solution, is to replant all of the desert lands with native trees, grasses and wildflowers, to cool the barren surfaces, so that the sun's heat will not get trapped by the CO2 and methane in the air.
That is what the Saudis and 24 countries are doing right now, planting 50 billion trees with their Middle East Green Initiative, which India is a member of, picture from the COP27 meeting which put that project together.
By planting back that insulating layer of local native vegetation on the barren desert soils, that will cool Global Warming immediately on that spot, whereas reducing or removing the CO2 will take decades to centuries to have the same amount of effect.
