‘No evidence’ bacteria ate methane BP spill

Posted on May 28, 2011 by Rolf Schuttenhelm

A group of 13 marine scientists* from 12 different institutions in the United States and Germany have in Science criticised a January publication in that same journal, which stated ‘almost all’ of the spilled methane had been consumed by microbes, … Continue reading →

New infographic explains cloud geoengineering story

Posted on May 18, 2011 by Jorn van Dooren

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:

Thermohaline turbulence may increase West European warming

Posted on May 13, 2011 by Rolf Schuttenhelm

Two weeks ago scientists from NOAA reported in Nature they had discovered unexpected behaviour of an ocean current in the Indian Ocean, known as the Agulhas Current.

Hansen: paleoclimate shows 2 degrees climate target leads to multiple meters of SLR

Posted on February 7, 2011 by Rolf Schuttenhelm

Comparing previous interglacial periods, like the Eemian, to the present geological epoch, the Holocene, shows slight average temperature rises are strongly magnified around the poles. Even under the 450 Scenario 21st century sea level rise could reach multiple meters. “Current … Continue reading →

2010 Amazon drought record: 8 Gt extra CO2

Posted on February 4, 2011 by Rolf Schuttenhelm

The 2005 Amazon drought was unprecedented. It was thought to occur just once in a century. But last year was even worse, leading to massive biomass degradation and CO2 emissions. And yet another 2010 climate record.

Geoengineering La Niña

Posted on January 30, 2011 by Rolf Schuttenhelm

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 →

Tibetan dust could lower Himalayan glacier albedo

Posted on January 6, 2011 by Rolf Schuttenhelm

Changing wind patterns due to current climate changes sweep up more dust from the Tibetan Plateau, lake sediment measurements show. Jessica Conroy, a graduate student in paleoclimatology at the University of Arizona in Tucson, presented a dust record dating back … Continue reading →

GCM study finds no Arctic albedo tipping point

Posted on December 20, 2010 by Rolf Schuttenhelm

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 →
