You're talking about what the media or politicians report. Things like "the climate crisis will come in 12 years" have usually no scientific basis and often are based on much more conservative predictions like 1.5C° warming cannot prevented after 12 years of "business as usual" because temperature increases lag CO2 emissions by several years. This doesn't actually mean that we will see 1.5°C warming within the next 12 years. It might even take 20 years or more. 1.5°C warming will suck but it's not the end of the world. It just means that we will have to adapt to a new way of living and we can't go back to the good old days.
