Harnessing nature to restore the oceans and fix the climate crisis
For All of Us
Seafields will develop proprietary underwater pipes to upwell nutrients that will feed the Sargassum we’ll grow in the mid-Atlantic.
Sargassum influx: nature’s gift to restoring the oceans and helping fix the climate emergency
Carbon sequestration needs more attention.
Stopping ongoing carbon emissions isn’t enough.
We need to scrub existing pre-industrial CO2 as well, and quickly, to avoid us reaching key climate tipping points.
Current efforts are focussed on cutting the 50 gigatons of CO2 we emit each year (GtCO2), but little thought is being put into sequestering the ~1830 GtCO2 post-industrialisation emissions that remain.
It’s difficult to visualise the scale of the problem.
One gigaton = a billion metric tons. That is the equivalent to the CO2 emissions of Germany in 1990. The 276 million cars in the US release about 1.27 gigatons of CO2 per year. The entire mass of humanity = 287 million metric tons. Sequestering more than 50 GtCO2 a year would need collaboration at a scale humanity has never seen before.
Is terrestrial carbon sequestering really nature’s best solution?
We need to plant 1.2 trillion trees to solve the problem terrestrially. The geopolitical challenge of this makes it practically unachievable, plus trees take time to grow.
