Ecological doom-loops: Why ecosystem collapses may occur much sooner than expected
phys.org
Around the world, rainforests are becoming savanna or farmland, savanna is drying out and turning into desert, and icy tundra is thawing. Indeed, scientific studies have now recorded "regime shifts" like these in more than 20 different types of ecosystem where tipping points have been passed. Around the world, more than 20% of ecosystems are in danger of shifting or collapsing into something different.

an ecosystem predicted to collapse in the 2090s owing to the creeping rise of a single source of stress, such as global temperatures, could, in a worst-case scenario, collapse in the 2030s once we factor in other issues like extreme rainfall, pollution, or a sudden spike in natural resource use.

There is no way to restore collapsed ecosystems within any reasonable timeframe. There are no ecological bailouts. In the financial vernacular, we will just have to take the hit.

    My parents don’t believe in climate change because of their religion, which means they will NEVER change their minds.

    “Well, the earth is only about 6000 years old, so all those numbers are meaningless because they’re based on false assumptions…”

    I tried telling them, “You believe in God, well, he gave you a brain, don’t you think he wanted you to use it and maybe not take a couple thousand year old story so literally?” They weren’t happy.
