Ocean warming speeds up ice sheet melting Greenland and Antarctica

In March we learned ice sheet formation is two-sided. On Sunday, sipping coffee whilst reading the latest Nature Geoscience, we learned the same might go for ice sheet melting. If so, melting would likely accelerate over this century and sea … Continue reading →

Antarctic krill promotes CO2 uptake by plankton through iron fertilisation

Iron is very rare in the upper layers of the world´s oceans, where photosynthesis is possible and therefore biological activity and concentration of living biomass is highest, making the mineral a growth-limiting nutrient in 40 percent of the world’s oceans, … Continue reading →

Today’s paradox: hunt for oxygen-rich seas may be bad news for hypoxic plankton

Certain types of plankton have adapted themselves to living in water with low oxygen content, so they can hide away from fish when digesting [through anaerobic glycolysis] and meanwhile suppressing their metabolism. Only at night, when in search for food, … Continue reading →

Oceans to enter Holocene Mass Extinction

The cumulative effect of environmental threats like climate change, ocean acidification and overfishing, brings the world’s interconnected ocean close to a phase of extinction of marine species that is ‘globally significant’ and unprecedented in human history, an international panel of … Continue reading →

Current CO2 rise 10 times as fast as PETM climate disaster

For the layman paleoclimatology is ‘proof’ that any climate change is natural. For educated thinkers the lessons from the long ago contain the biggest warnings for the current artificially created state of our planet.

Sulphur switch in algae new route to marine cloud geoengineering?

Marine bacteria produce two types of sulphur compounds as they eat dead algae biomass. The one, methanethiol, or MeSH, is cycled downwater into the food chain. The other forms a liquid aerosol, dimethylsulfide, or DMS. The latter plays an important … Continue reading →

New cloud geoengineering research casts doubts: 70x less effective & smallest salt aerosols increase warming

Marine cloud seeding is one of the best documented geoengineering proposals. It is centred around the idea that some forms of clouds tend to have a net cooling effect on the Earth’s climate, by increasing albedo or reflectivity. Our regular … Continue reading →
