    1. these are not represented in the models, they're not in the global carbon budget estimates, they're not in the IPCC.
      • for: carbon budget - underestimate, IPCC - underestimate, 1.5Deg C - underestimate, question, question - revise 1.5 Deg C target downwards?
      • highlight

        • the 1.5 Deg C target does not account for cascading tipping points. In fact the cascading tipping point research is not accounted for in any of:
          • current climate models
          • global carbon estimates
          • IPCC
        • the implications are that the carbon budget is even smaller than the current number.
        • the implications are that 1.5 Deg C is not the threshold we should be aiming for, but even less. We are now at 1.2 so it has to be 1.3 or 1.4.
      • question

        • Given the underestimates, should the target actually be revised downwards to 1.3 or 1.4 deg C?
    2. there are so many uncertain factors on soil carbon, ocean carbon, ocean heat, ice melt, biodiversity loss, biome tipping points.
      • for: precautionary principle, fossil fuel phase out, carbon budget - uncertainties, carbon budget - underestimate
      • highlight
        • the precautionary principle dictates that the uncertainties in:
          • soil carbon
          • ocean carbon
          • ocean heat
          • ice melt
          • biodiversity loss
          • biome tipping points
        • implies that the any one of these can easily bring our remaining carbon budget down to zero.
