Protesters march in the streets in an “extinction rebellion” against the climate crisis, with some (but not all) of their leaders claiming that climate tipping points could kill billions in the coming decades.

But dismissing the severity of climate impacts and the real possibility of worst-case outcomes is also an extremely dangerous gamble.
