According to a report, a cop26 draft aims to limit global warming, currently 1.2 Celsius above pre industrial levels to 1.5-2C above pre industrial levels by way of nationally determined contributions, or plans containing targets for emmisions.
Reportedly, net zero relates to a reduction of emmisions as far as possible, and where alternative technologies aren’t available offsetting irreducible emmisions by fostering carbon sinks, that is anything that absorbs carbon such as trees and forests. Reportedly, the amount of carbon on earth has never changed, it flows from the soil to organisms to the air, being released and absorbed. Conclusion being carbon gases will be assimilated, not so any attached pollutants.
According to reports, global warming is caused by greenhouse gases emitting radiant energy with a wavelength of between 3 and 100 micrometres.
Non polluting fuels don’t create a haze, such as wood and oil fired central heating. Nuclear energy uses uranium and burns much hotter than coal. According to reports, light water reactors form the major part of new nuclear reactors for commercial and naval purposes and are available from the us, Russia and France for electricity production. Reportedly, water is taken from a nearby river or ocean as a necessary coolant, and is pumped back in a heated condition or dissipated as steam. According to reports, problems are water becoming contaminated with nuclear fissions, and decay heat, necessitating water to be pumped for one to three years after shutdown. Reportedly, if the temperature exceeds 2200 C the water becomes explosive.
