Sudden Jump In Published Findings on Tipping Activation

Bruce Melton PE, Climate Change Now Initiative Science is slow. It has been slower than climate change for decades and as that science has warned, if we did not act promptly and appropriately, the speed of climate change would increase further and dangerously. We now find this future…

Land Sink Now Degrading

Duffy 2021 reports that within the last decade, the average global temperature for the warmest 3-month period passed the thermal maximum for photosynthesis. This means that on average, photosynthesis has peaked with warming and is now in decline, despite broadly accepted projections that photosynthesis would continue to…

Geoengineering Reduces Cumulative CO2 – Keith 2017

Summary - "If solar geoengineering were used to hold radiative forcing constant under RCP8.5, the carbon burden may be reduced by ~100 GTC, equivalent to 12–26% of twenty-first-century emissions at a cost of under US$0.5 per tCO." It is also important to note that all other warming related responses…
