Since I am concerned with abrupt climate change - and it‘s not a very long period, 3 or 4 years - I can observe a game in mainstream media and their publications about climate change: The period of time until the temperature of our planet is rising so steep, that we are facing consequences. First the period has been infinite, because in most publications it has been mistrusted if there is a measurable climate change. If yes, it may not be anthropogenic. Then in some publications, that agree to climate change, the prognosis has been maybe 2° C until 2100.
Meanwhile, the methane situation looks very threatening. The image [below] gives an update on the high levels recently recorded at Barrow, Alaska.
