   Redwoods are growing almost as fast in the UK as their Californian cousins

   New study finds that giant sequoias add 70 cm of height and store 160 kg of carbon per year.

     Maybe the world needs more #ReedWoods/ #GiantSequoias ? 😀

     Added benefit: everyone can feel like in kindergarten again. 😉

     A dast growing #eucalyptus tree stores only 0.10 pounds annually in do most of the other trees 🌳 I checked here:

     Assumption:
     We need to make animpact ASAP due to the unpredictability of the #TippingPoints. Therefore, I chose the minimum, 10 years.

     @HistoPol @arstechnica
     Better plant grasslands then. Redwood forests tend towards an overall density of 80 trees/acre. That's 160 kg * 80 trees per year or about 12 tons of carbon removed (or about three car-years' worth). Grassland ecologies can do about 49 tons per acre, and all without destroying your native ecology. But if you really want to cut down carbon emissions in the UK, stop trying to have US-style car centrism and bring back bikes and public transit.

     #Grasslands. Excellent idea.

     So, this begins to explain why the carbon-offset programs for #reforestation never seem to have been a good idea from the beginning, if even the #GiantSequoias are not really up to the task.

     I just tried to read up on the subject.

     It seems that, as with the introduction of new animals (#neobiota, e.g. bunnies to #Australia) the introduction of new plants( #neophytes*) can be a huge source of disruption regional #ecosystems as well.

     After reading through the aforementioned article about #grasslands, I now begin to understand the complexities involved.

     I have a hunch that, from a systems point of...

     There's a really pertinent story about one such scheme in Scotland where planting spruce destroyed peat marsh, an excellent carbon sink biome, and releasing more carbon than the trees captured.

     The short form, preserving existing ecosystems and improving their conditions works out better. If Brazil slashed their agricultural export industry and let the farms return to the wild, that’d help for instance.

     #ClimateCrisis

     In general, I agree. However, for the #Amazon #rainforest, there might not be much hope:

     Huge regions of earth will become uninhabitable , e.g. the northern part of #SouthAmerica and #Africa.

     I got this from a scientific article some months ago, the post of which, alas, I cannot find anymore.
