Because this
angle dictates
how much gravitational - wave energy is emitted in Earth's direction, combining polarization with other data allowed researchers to derive a more
precise estimate of total energy released by the event and so reduce the error in their distance estimate.
We don't have to worry about the enforcement
angle until the world's politicians have agreed upon the official procedure for measuring the temperature of the earth, the optimum temperature of the earth, the
precise percentage of CO2 that would establish and maintain that ideal temperature, the number, location, and specifications for the CO2 monitoring stations, who would be in charge of the world CO2 monitoring system, who would pay for it, the thousands of pages of regulations and taxes that would require enforcement, who would pay for the regulatory bodies, who would collect the CO2 taxes,
how the taxes would be distributed etc..
