"equatorial fertilization reduces energy flows to higher trophic levels, expands oxygen-minimum zones (OMZs) and reduces macrozooplankton biomass." But never ever mention the elephant in the room: methane! #climate #earth

Climate benefit and ecological cost trade-offs for ocean iron fertilization - NatureA process-rich global biogeochemical model is used to determine the trade-offs between carbon dioxide removal efficiency and ecosystem impacts in ten ocean ocean biomes following ocean iron ...www.nature.com

Interesting how many signals we have now of becoming more active super volcanoes Ice shield mass loss, sea level rise, intensification of hydrological extremes all seem to have an profound effect on tectonics and thereby underlying magma flows Cool experiment Models say no, so... #climate #earth

One of Earth’s most explosive supervolcanoes is recharging with fresh magmaDeep beneath Japan’s mostly submerged Kikai caldera, scientists have discovered a vast magma reservoir that appears to be filling again. The volcano produced the largest eruption of the Holocene 7,300...www.sciencedaily.com

It's not too difficult to understand: If a water plant spreads over wide parts of an ocean basin with warmer ocean temperatures driving proliferation with the root cause of N fixation in the oceans increasing you've got a planetary emergency as you do not know how it can further expand #climate

Sargassum, the smelly nemesis of beach vacations, has become a self-sustaining disaster that will keep coming backCommunities and entrepreneurs are experimenting with ways to turn this nuisance into a valuable resource.theconversation.com

Since the record North Atlantic heat in 2023/24 Sargassum underwent a regime shift to higher values Peaked the last two years Will likely spread also in the Pacific Higher rates of N fixation seem to be the main driver Likely massive coastal methane signal in the future #earth #climate

This would make sea level rise a negative long term feedback "Strongest carbon burial occurred within a relatively limited window, when sea level stood about 10 to 40 meters above its present height. Within this sea level “sweet spot,” The problem: high biomass toxic blooms releasing CH4 #climate

Earth’s Hidden Thermostat Has Regulated Climate for 60 Million YearsResearchers found that a narrow range of ocean conditions maximized carbon burial for millions of years at a time.scitechdaily.com
