I don't know where you live or where you heard that but it is not a lie that was told in france at least. If you want a "lie", it was how far in the future that was going to happen, but that's mostly because the deniers got control of the messaging for a long time.
I know it's a cold and cynical take, but if it has to happen somewhere, better for it to happen in Europe, the US, or other developed countries. These countries can at least do something to keep climate crisis from getting worse. (Or... more realistically, to keep it from getting worse too fast.)
