Bits of Geoengineering

New infographic explains cloud geoengineering story

It first cost us thousands of words and various articles on cloud whitening geoengineering and presumed cloud climate feedbacks. But we feel these 8 Rembrandts might do a much better job at communicating some of the most confusing climate science:

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 →

Geoengineering can save Greenland, model suggests

We recently witnessed a new Greenland melting record. And according to a new paleoclimate comparison by James Hansen we could be in for meters of sea level rise within this century, due to expected non-linearity of the melting process.

Geoengineering La Niña

According to the WMO the current La Niña episode will continue to exist for at least another 2-4 months. Other sources state it may last until 2012. This La Niña could be the strongest in decades and is likely to … Continue reading →

Getting practical on geoengineering: the cheapest way to lift 1 Mt of aerosols

Aurora Flight Sciences recommends Aurora Flight Sciences. At least that’s what David Keith, Climate Professor at the University of Calgary and a leading expert on geoengineering leads to suspect in their joint cost analysis, published three weeks ago.

Shellfish malformed by ocean acidification

A publication in next week’s edition of PNAS magazine elaborates on the effects of continued acidification of ocean waters on shellfish. Larvae of two species of shellfish commonly found along the American East Coast (Northern quahog and Atlantic bay scallop) … Continue reading →
