We recently reported on a possible negative carbon feedback of forest soils in higher latitudes: when such soils warm, nutrient availability may increase, as would (therefore) biomass production and CO2 uptake. But not all climate feedbacks operate through temperature. It … Continue reading
And already suffer biodiversity losses during the decline from pH 8.1 (preindustrial) to 7.8. That latest number is the expected acidification for the end of this century according to IPCC 4AR, a theoretical scenario and a dangerously often quoted underestimation … Continue reading
Same story as yesterday, but now 635 million years earlier. This time again no evidence can be found that it were microbes that ate climate-disrupting amounts of methane, at the end of the Marinoan ice age, better known as ‘Snowball … Continue reading
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
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.
The Earth is en route to its sixth mass extinction, say a group of paleobiologists in the latest edition of Nature.
Pricewinning British science journalist Tim Radford argues that researchers are not hopeless at explaining their work to a general audience.
Music is everywhere in our lives from film, television, marketing, radio, and so on. Even the musical hum of cars outside our offices is a form of music; although it’s debatable if it is pleasurable. Those who work with music … Continue reading
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
According to ‘The End of Cheap Coal’ in last weeks edition of Nature, outdated reserve estimates and economic forces will lead to a peak in coal production within two decades. Ambitious geopolitics are still left out of that equation, which … Continue reading
