>have this pet theory of mine that planting trees could also mitigate rising sea levels since trees Contain water. Is that dumb ? Unfortunately, we would likely have to cover more land than there is on the entire surface of the earth to stave off even a meter of sea level rise. For reference, the sea to land-ratio on earth is around 70/30, and a tree of 15 meters at 60 cm diameter is approximately 5 cubic meters in volume, and a tree contains around 30-50% of its volume in water. The average forest density appears to be about 50-100k trees per square kilometer. We should still plant trees en masse, but as a solution to sea level rise it's probably not viable.
