Tired light theory requires:

  1. Distant galaxies to be blurry (they aren’t)
  2. Events in faraway galaxies to happen at the same pace as nearby events (they don’t. Time is dialated just like frequency is redshifted)
  3. Cosmic background radiation would not be a black body
  4. Constants c, G, and hbar would change through the history of the universe.

Computer simulation provides 4,000 scenarios for a climate turnaround (phys.org) en

Using an extensive computer simulation of the climate, the global economy and the global energy system, researchers at Paul Scherrer Institute (PSI) have been analyzing different ways of mitigating climate change, together with colleagues from the US, China, Ireland, Finland and Sweden.

They do discuss several commonalities in the paper.

If it is to meet the Paris Agreement target, the worldwide average carbon price in 2030 needs to be equal to today's (2022) highest carbon taxes ($ 130–137 tCO2-1) that are observed in very few countries

Electricity cannot decarbonise the entire system alone, and hydrogen extends electricity's reach to hard-to-electrify sectors

The contribution of nuclear power in electricity production increases in the long-term in the decarbonisation scenarios. This is especially pronounced after 2050/60, when the wind and other renewable potentials are fully exploited and the additional electricity supply to meet the increasing demand needs to remain carbon-free.
