This is an interesting article but it misses a key point: Why did we pick the baselines we did?

The first baseline to consider is CO2. But CO2 is also a fertilizer for plants and literally every plant we exists because of CO2. The more CO2, the better plants grow. They actually pump CO2 into greenhouses to make everything grow faster. Also interesting to note on CO2 is that only 12% of the increase over the last 150 years can be carbon traced to Fossil Fuels. Even if we stopped ALL emissions, CO2 will increase... Why?

The second baseline is Temperature. Yet we know even less about temperature than we do CO2 and modeling temps is wicked hard. We have yet to figure out how much impact the Sun is having let alone CO2 impacts. Yet we know it's been much much warmer in the past and we also know that temperature changes have been much more dramatic in the past. So why this baseline?

I ask these two questions in the essay linked below not to challenge the science of whether the climate is changing, but to understand where we are measuring those changes from, and why. And don't worry, the essay proposes that even thinking about these questions can result in better ideas for what we need to do about it.

Devansh - I am sooo glad that you wrote this piece. As someone working at the intersection of AI and sustainability, and in sustainability for the last 15 years, I feel that this is not spoken about enough. None of the AI models out there talk about their environmental performance or how they plan to be climate neutral. They don’t care. But, if we have a chance to build the next wave of large scale / civilization changing infrastructure, why wouldn’t we do it correctly?

PS: did you lose subscribers writing this?
