- headmelted 6y agoThat’s exactly my point though. From the link: “Even if humans stop emitting greenhouse gases today, these gases would still be elevated by the year 12000.” Creating a temporary carbon sink in the form of a desert forest helps in the short term, but is not negative carbon. It’s net carbon neutral. Genuinely being “green” in this instance requires sequestration of the existing gas from the atmosphere.
- Maursault 6y agoYeah, and it will be again in 10,000 years, but as per the wiki you site, this is due to Earth's orbital period [1], and it doesn't last very long. And during Green Sahara (if our species is still around to see it) we're likely to see deserts where we now have green.
