2010 brought CO2 record – 450 Scenario does not allow any further growth

We really thought we had all the climate records for 2010 neatly piled, but had all forgotten about this one. Deforestation and other land use changes excluded, simply burning fossil fuels in 2010 we emitted 30,600,000,000 tonnes of CO2. That’s … 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.

GCM study finds no Arctic albedo tipping point

The albedo effect still acts as a positive feedback to warming and melting. In fact the general circulation model study shows Arctic sea ice melting will speed up over recent years. From 2020 to 2030 more than 2.5 million square … Continue reading →
