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.

  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.

    Chaos theory
    
    Chaos theory is an interdisciplinary area of scientific study and branch of mathematics focused on underlying patterns and deterministic laws of dynamical systems that are highly sensitive to initial conditions, and were once thought to have completely random states of disorder and irregularities. Chaos theory states that within the apparent randomness of chaotic complex systems, there are underlying patterns, interconnection, constant feedback loops, repetition, self-similarity, fractals, and self-organization. The butterfly effect, an underlying principle of chaos, describes how a small change in one state of a deterministic nonlinear system can result in large differences in a later state (meaning that there is sensitive dependence on initial conditions). A metaphor for this behavior is that a butterfly flapping its wings in Texas can cause a tornado in Brazil.Small differences in initial conditions, such as those due to errors in measurements or due to rounding errors in numerical computation, can yield widely diverging outcomes for such dynamical systems, rendering long-term prediction of their behavior impossible in general. This can happen even though these systems...

  It'd be interesting to know how confident the scientists are in their models.

  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.

    Natural Geoengineering: can the Ecosystem Save the Planet?
    
    from Ugo Bardi
    
    On February 28th, we discuss “natural geoengineering,” the capability of the Ecosystem to contrast and, in part, remedy the damage done to it by humans. It is a webinar organized by WAAS (World Academy for Arts and Science) in collaboration with the Club of Rome. We discuss the role of forests and oceans, and we compare it with some more possible actions. We also discuss the human side of the problem, especially for the less privileged populations living in the regions that risk being the most negatively affected by global warming.
