    1. Across all global land area, models underestimate positive trends exceeding 0.5 °C per decade in widening of the upper tail of extreme surface temperature distributions by a factor of four compared to reanalysis data and exhibit a lower fraction of significantly increasing trends overall.

      for - question - climate crisis - climate models underestimate warming in some areas up to 4x - what is the REAL carbon budget if adjusted to the real situation?

      question - climate crisis - climate models underestimate warming in some areas up to 4x<br /> - What is the REAL carbon budget if adjusted to the real situation? - If we have even less than 5 years remaining in our carbon budget, then how many years do we actually have to stay within 1.5 Deg C?

    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.
