I think the tipping point has long since been breached, we had enough warnings over the past decades, both from scientists and those with a more spiritual viewpoint, like the Hopi. Since spirituality isn't currently trendy in our beyond materialistic Western world, I won't labour the point on that, but there's plenty out there if you feel like looking.
If we are very, very, very lucky, it might be possible to stabilise the situation, but not without addressing the fact that the planet has too many humans on it OR without us accepting that every aspect of the way we choose to live our lives will have to change dramatically OR both. This is just one of the elephants in the room; in my lifetime alone, the global population has more than doubled, and with it, the strain on resources on a finite planet and our effect on the climate.
As it is, in the second half of my lifetime, I'm expecting to see a huge increase in these formerly "extreme" weather events. Now that London's starting to experience flash floods relatively regularly, the mainstream media might start paying a bit more attention (though I'm not holding my breath); places like the East of England, and Cumbria, and the midlands around Gloucester have long had to just cope with it.
In the West Country this year, for the first time ever in the UK, the Met Office issued a high temperature warning. Meanwhile the likes of the Daily Mail and the Express and the Sun keep bleating about what a wonderful thing hot weather is, completely ignoring the strain it puts on infrastructure and, for those with certain health conditions, the human body itself.
And that's just the UK, where, for now, we still have a relatively mild climate. It's far worse in parts of Europe, India, and North America, to name just three. And if the likes of Farage and Hopkins were incensed about "ordinary" refugees, they're going to LOVE climate refugees...I can see them staffing the gunboats in the Channel now...
On a personal note, eating meat, flying everywhere at the drop of a hat, fast fashion, getting in the car to drive a couple of miles - it won't be long before it's only the very rich who'll be able to afford to do that kind of thing on a regular basis. Life is likely to become much more localised (unless you're a billionaire who thinks space tourism and a permanent base on the moon for rich folk is the way forward, of course...)
On the plus side, we may stop being such a throwaway society and learn to repurpose or reuse or remake, like the War Generation had to. Solar power and other alternative power will hopefully take a massive step forward (as long as the NIMBY folk don't get too upset about those fields of panels/turbines next to their mansions), and localisation may lead to a stronger sense of community. The education system may even finally start teaching kids useful skills instead of making them memorise the wives of Henry the Eighth ad infinitum, employ obscure mathematical techniques, and recite Shakespeare at will. (And no, I don't think Shakespeare is a waste of time, but I just wonder what practical application it might have for growing crops, say.)
The overall ecological situation is just one more reason I don't understand why the UK willingly made itself such an insignificant player on the world stage and why decades of European partnership were thrown down the drain for the sake of a vanity project. The Netherlands, for instance, has long lived with floods, and they have come up with innovative solutions (houses that rise on stilts). And those shortages in the supermarkets at the moment? Almost certainly just a taste of what lies ahead, if you'll pardon the pun.
In the meantime, for however long I've personally got left, I'll just keep buying local and second-hand; limiting very occasional holidays to trips to see the family in this country; planting my carrots, potatoes, and turnips (or squash, cucumber, and peppers when the climate starts getting hotter and wetter), and reading/watching dystopian/speculative science fiction (and actual science, obviously, as well as history), so that whatever scenario happens, it doesn't come as too much of a shock...
