Although the latter accelerate the rise of CO2 in the atmosphere, on the other hand, radiative forcing (which causes warming) increases only with the logarithm of CO2 concentration, and therefore roughly linearly since the 1970s.

OK, on to methane in the environment: The headline here – whether you’re talking about atmospheric concentrations, climate impacts, or emissions – is that there is a lot less methane than CO 2 , but it’s a more potent climate heater and it’s increasing faster.

But if primordial black holes (PBHs) did form as early as one second after the Big Bang, during the “radiation dominated” era, things would be different. As Hawking had first realized, black holes evaporate over time, via Hawking radiation. Black holes formed much later, only after the first ancient stars had died.

These values can be used in a variety of ways.
