Marine CO₂ removal lacks standardized indicators to quantify carbon removed and environmental impacts. This absence of reliable metrics prevents verification, inhibits investment, and blocks entry into carbon trading systems.

iopscience.iop.org/article/10.1...
a schematic diagram showing various processes and related indicators for monitoring carbon removal in ocean systems, based on analyzed literature. The diagram divides the processes into three categories represented by different colors: Blue Carbon (green): Focuses on processes related to carbon sequestration and the role of marine ecosystems in capturing and storing carbon. Artificial Upwelling (yellow): Depicts processes that involve artificial interventions in marine environments to increase carbon capture. Ocean Alkalinity Enhancement (blue): Illustrates methods that increase ocean alkalinity, which can help enhance carbon removal. The processes depicted in the diagram include: Carbon Sequestration Potential: This refers to the ability of oceans to capture and store carbon, with an indicator for monitoring this potential. Mineral Dissolution and Seawater Alkalinity Change: These processes are associated with changes in seawater chemistry, enhancing carbon sequestration through increased alkalinity. GHG Emissions: This represents the release of greenhouse gases, which can be measured to monitor the net carbon dynamics in the system. Carbon Removal Rates and Respiration: Shows how carbon is removed from the atmosphere and the role of respiration in this process, measured through carbon flux indicators. Primary Production and Water Masses Detection: This includes the detection of primary production (e.g., photosynthesis) in marine systems that leads to organic carbon formation. Sinking, Remineralization, and Burial: These processes involve the movement of carbon from the surface to deeper ocean layers, with some carbon remineralized and some buried in sediments. 🧪🌊

Climate tipping points are close: scientists urge radical action before it’s too late

Tipping point risks are interconnected. Most interactions among them are destabilising, meaning that tipping one system into disaster makes tipping another more likely.

Climate tipping points are close: scientists urge radical action before it’s too late
Dangerous climate tipping points will threaten food, water and coastlines. They’re irreversible and only radically accelerated climate action can stop them now.

Nobel Prize winner James Watson died at 97 having made monumental contributions to science while also leaving a legacy tarnished by sexism, racism and the erasure of colleagues like Rosalind Franklin. His life illustrates both the best and worst of the scientific establishment.
James Watson exemplified the best and worst of science – from monumental discoveries to sexism and cutthroat competition
James Dewey Watson is best known for his Nobel Prize-winning discovery of the structure of DNA. Controversy around who should be credited highlights the challenges of scientific collaboration.

Absolutely fantastic contribution by @kevinclimate.bsky.social on Radio4's Today program this morning.
Pointing out that tackling the climate challenge without tackling social and economic inequity -both on a national and international level- is an illusion.
Expensive, futile window dressing.

I'm sure it's totally coincidental that the AoNZ government's changes to the Marsden Fund have been followed by successful applications led by female investigators dropping from 55% to 33%, and successful applications led by Māori investigators dropping from 13% to 5%. 🫠 🧪
