315,000 tons of CO2 over 10 years, so 31,500 tons per year.

40 billion tons of CO2 per year will be created globally by 2030.

So Microsoft's deal will remove 0.00007875 percent of globally emitted CO2 on an annual basis.

This process would have to be scaled up by 1,269,841 times to capture all emitted CO2, neglecting the increased CO2 emissions associated with the scaling itself.

That seems like a lot of work just to enable humans to increase our numbers and consumption on a finite planet.

Can someone please remind me why more people consuming more resources is a given?

Because nature existing in a vaguely pre-human state is only a means to an end. Climate change is only a problem so far as the problems it creates get in the way of humans and their actual goals. Humanity first.

Even if we stopped all emissions tomorrow, we would probably need to do stuff like this because the CO2 level is already too high.

About $25T, about a third of global GDP to scale up to full offset. Even more to offset the last century. We need massive innovation in this space. Even if we make reliable and scalable fusion we are still far away because we need enough batteries to offset all other carbon emissions in planes, cars, and other vehicles.
