COP 27

Introduction:
- Earth may have passed through five dangerous tipping points due to the 1.10 C of global heating caused by humanity to date.
- Technology became a survival strategy for human species, but the degree of techno-determinism that exists in the strategy to reverse climate change is alarming.
- Technology is unprepared to deal with the challenge, which requires a societal overhaul & a zero emission strategy.
Technical Optimism:
- COP26 at Glasgow fuelled technological optimism.
- There was an observation that every technological solution discussed at COP26 depends on three resources: nelectricity(non-emitting electricity generated by hydropower), carbon capture & storage(CCS) or biomass.
- The total demand for those resources required by the plans discussed at COP26 cannot be met by 2050.
- Currently there is 4kWh/day of nelectricity but COP26 plans require 32; 6Kg of CCS per person per year is available now but COP26 requiure 3,600.
- A person consumes 100kg/per year of plant based food, but producing enough bio-kerosene to fly at today's levels requires 200kg of additional harvest.
- There is no possibility that the supplies of these will be near the levels required by the plans discussed at COP26.
- A recent study reported that the world would need a nuclear plant's worth of clean-energy capacity everyday between 2000 & 2050 to avoid catastrophic climate change.
- MIT technology reported that at the given rate, the world will take nearly 400years to transform the energy system.
- Tech-centric mitigation conversations leave forest economies which are the best carbon removal instruments, to the ideological fringes of climate conservation.
- Climate action requires the same amount of investment in conservation as in shiny new technology transfers.
- While there was the deforestation ending climate commitment at COP26, the nature of the pledge was vague.
- Countries may attempt to achieve their 'net zero deforestation goals' through monocluture farming.
- The climate crisis is intertwined with other complex issues which means that it must be insisted on multi-pronged, interconnected climate solutions.
- Forests which are home to 80% of terrestrial wildlife, are at intersection of climate change.
- Forests absorb a net 7.6 billion metric tonnes of carbondioxide a year. A new study found that their biophysical aspects have a tendency to cool the earth by an additional 0.5%.
- The conservation of forests can provide upto 37% of the emissions reduction needed to tackle climate change.
- The green infrastructures-salt marshes & mangroves are 2-5 times cheaper than grey infrastructure-breakwaters.
- The annual gross carbon emissions from tropical tree cover loss between 2015-17 was equivalent to 4.8 billion tonnes.
- This causes more emissions each year than 85 million cars do in their life time.
- Nearly 34% of total net anthropogenic green house gas emissions came from the energy supply sector, 24% from industry, 22% from agriculture, forestry, 15% from transport & 6% from buildings.
Conserving Natural Sinks:
- The IPCC land report estimates that land serves as a large carbondioxide sink.
- There is a growing body of evidence that a large proportion of the required removals could be achieved by conserving-natural sinks, improving biodiversity protection & restoring ecosystems.
Preserving earth's cyclical processes by protecting terrestrial ecosystems, natural sinks & transformative agricultural practices is far more equitable & cost-effective way of tackling the climate crisis than it is being done.
Epilogue:
Technology can assist us, not lead us, on the pathway to a sustainable, regenerative & equitable world.
