August 13th was Earth Overshoot Day. The correct date, if calculated precisely, would come earlier and earlier each year, the current choice is just an approximation. This year, the year 2015, by sometime around August 13th, humanity had consumed as much of what we require from the lands and seas as our planet can sustainabley … Continue reading Global Day of Overshoot

Caltech: Robotic Ocean Gliders Discover Why Antarctic Polar Ice is Melting
Dear Readers, Find below an interesting press release I may as well share verbatim: The rapidly melting ice sheets on the coast of West Antarctica are a potential major contributor to rising ocean levels worldwide. Although warm water near the coast is thought to be the main factor causing the ice to melt, the process … Continue reading Caltech: Robotic Ocean Gliders Discover Why Antarctic Polar Ice is Melting
TED – Gavin Schmidt on climate modeling
In the video below Gavin Schmidt gives a "TED Talk" on climate models, taking us from an overview of their construction to the resulting emergent processes and their skill at reproducing much more than a global average temperature trend. Gavin is an excellent communicator and a true hero in humanity's fight against itself over the … Continue reading TED – Gavin Schmidt on climate modeling
Coal is Bad
Coal-fired electricity production is bad on so many levels. You'd think humans could learn from history, but sadly, no, and no.Â The childhood asthma statistics alone should be enough.Â Coal burning power plants are a leading producer of asthma causing pollution.Â And then there's the mercury...and the mountain-top removal, and the waste products..and, well, when … Continue reading Coal is Bad

Inside an Antarctic Time Machine
Most of us interested in climate science understand the uniqueness and importance of deep ice cores. It is truly a remarkable record of many aspects of past climate including dust, methane, sea level proxies and carbon dioxide. The video below (a YouTubed TED Talk)is a very fascinating look at what it takes to retrieve one. … Continue reading Inside an Antarctic Time Machine
This, from adelady, is so well put I just had to highlight it. It is a response to the usual "we'll just deal with whatever climate change throws at us later" inactivist argument: The one thing we do have in our favour is our astounding intelligence - it's also astounding how we fail to use … Continue reading Nicely said!
Regional climate response to solar-radiation management
Geoengineering is getting more and more attention in political discussions as well as research. I am by no means a proponent of any geoengineering scheme I have heard of and the majority of them try to address surface temperature only and therefore do nothing about "the other CO2 problem", aka ocean acidification. I must confess … Continue reading Regional climate response to solar-radiation management
Putting out fire with gasoline?
Corexit was a big news topic at the beginning of this tragic Deepwater Horizon oil spill in the gulf of Mexico but it seems little talked about now. There is no question that BP's calculation in its decision to use so much of this toxic chemical prioritizes the cosmetics of the situation over ecological impact … Continue reading Putting out fire with gasoline?
