Daf with all respect you say we have about a decade to avert disaster simply because that’s what you hear from else where, from others, if they said 20 years you would be repeating that.. Its been left so long now it’s made matters so much worse, the people in the know have been stating this for years, it’s been ignored, and tbh I think this COP 26 seems a half hearted attempt, not by all but by those who have more say than you or I.. Time will tell and hopefully it will work to plan, and the planet can hopefully thrive from the out come.
Reality is we really do not know how long we have, perhaps it is already too late, maybe we have 10, 20 years. Differing opinions and differing interests are all at play.
