Mathematical Formula Predicts Global Mass Extinction Event in 2100 (vice.com)
Kate Lunau, writing for Motherboard: A new paper in Science Advances finds that a mass extinction period mirroring ones from our planet's ancient past could be triggered when humanity adds a certain amount of carbon to the oceans, which are home to the majority of all plants and animals on our planet. The paper pegs that amount at 310 gigatons. According to lead author Daniel Rothman of MIT, based on projections from the Intergovernmental Panel on Climate Change, we're on course to hit that number by 2100. After that, we enter "unknown territory." [...] Previous mass extinctions have happened over the course of thousands or millions of years, but the period of change we're in right now has lasted centuries at best, making it hard to compare them. Although plenty of experts say Earth is already experiencing a sixth mass extinction, that remains "a scientific question," Rothman, who is professor of geophysics in the MIT Department of Earth, Atmospheric and Planetary Sciences, told me. Once our planet hits the threshold he identified in this paper, he explained, it will kickstart changes that will "amplify" everything that came before. These same changes, to reiterate, have been associated with all previous mass extinctions on Earth.
there was a whole lot of shareholder value created before the extinction period hit.
Water is everywhere, our bodies are mostly water by weight, and yet you somehow want me to believe that if I'm submerged in water for just a few minutes I'll die? That makes no sense to anyone with a shred of scientific understanding of our bodies, or indeed basic biology.
I read the internet for the articles.
Here's the reason:

The key there is the number of mass-extinction events in our fossil records are directly connected with exactly these same events.
When methane vents open up under the ocean from various gethermal processes, they make this kind of gel (methane clathrate) that builds up at the ocean floor and sediment. There's a LOT of this stuff.
Anyway, when this gel reaches a certain temperature, the methane that was 'frozen' in it gets released relatively quickly. Methane already is like carbon pollution on steroids, and the scale of this release is literally world-changing, compared to say cow gas releases.
Again - this has happened several times already, taking out the large swaths of species of the planet each time. To the point that the ground leftover looks completely different across the entire planet.
It's kind of a big deal.

If you truly believe global warming due to carbon dioxide emissions is occurring, and you truly believe it's going to cause mass extinction in less than 100 years, then you want to prevent it in the most effective and expeditious method we have available - nuclear power.
If you think this is just an opportunity to advance renewable energy development, then you do not truly believe one of those things. Either you think global warming is not really happening, but you can use it to scare the world into adopting your preferred energy source. Or you believe it's happening but it's not really that serious, so we have plenty of time to develop renewable energy sources and phase them in.
Nuclear power doesn't have to be our final energy source. All we need is to use it to immediately arrest climate change, buying us more time to develop cleaner energy sources. Then we can phase out nuclear power in favor of renewables. Trying to jump straight to renewables is like being on a sinking ship, and insisting that nobody is allowed to use the existing life rafts. Instead you want us to research, design, and construct new life rafts to save ourselves, even if that might take more time than it takes for the ship to sink.
There's a possibility it might work. But why take that risk? Why gamble with all life on Earth? Implement the solution which is guaranteed to work (get on the existing life rafts / switch to nuclear power). Then once the immediate threat is over we can work on developing the ideal solution (develop new life rafts / develop renewables). If there's mass extinctions starting in 2100, it's going to be the fault of the environmental movement - who prevented us from immediately turning off fossil fuels and switching to nuclear, and insisted that we instead had to roll the dice and develop new unproven energy sources which still have problems with scalability and consistency.
Actually why don't you ask an actual botanist? Because I can tell you haven't.
Anyone with basic scientific literacy understand that plants live in ecosystems where they compete with other plants; furthermore any gardener will tell you that many plants are much more nitrogen and/or phosphorous limited than carbon limited. This means that the diversity of plant species will drop under higher CO2 scenarios as CO2 sensitive species outcompete less CO2 sensitive ones. High CO2 will be especially beneficial to plants like poison ivy that grow quickly and need lots of carbon for their cellulose structure.
Plant extinctions are easily deducible from a basic knowledge of ecology and gardening. Experimental work on CO2 impact is not promising either, indicating that many food species will produce more cellulose and other carbohydrate and less protein per pound. Plants experimentally grown in high CO2 environments develop abnormalities in their insect defenses that open them up to predation.
Understand by an "mass extinction event", we don't mean the extinction of all life. We mean a catastrophic loss of biodiversity. In a few million years, the Earth will be right as rain.
