You do realize that carbon sequestrated in a forest 100ks of years is prevented from contributed to global warming during all that time period, right?
> Not consuming fossil carbon means it will stay in the earth mantle for a geological time.
Nobody's arguing against that. But it's silly to argue that not consuming fossil fuels is a better solution than carbon sequestration. We urgently need to do BOTH. When your house is burning, you don't choose between calling the firemen and using the extinguisher - you do both.
> So carbon offsets by planting tree is a scam, and we need better than that.
That's naive and simplistic. If carbon offsetting was widely adopted, it would 1) be a fast way to start our transition towards a sustainable economy and 2) encourage reducing fossil fuel consumptions as it gets more and more expensive (as it will inevitably).
When it comes to fighting climate change, what matters is results, not this sort of uninformed rethoric.
