Coral chemicals protect against warming oceans

EMBARGO LIFTED: 4am AEDT, Thursday 24 October 2013

Nature paper reveals coral animals produce the ‘smell of the ocean’ – influencing cloud formation and protecting themselves against rising seawater temperatures. 

Australian marine scientists have found the first evidence that coral itself may play an important role in regulating local climate.

They have discovered that the coral animal—not just its algal symbiont—makes an important sulphur-based molecule with properties to assist it in many ways, ranging from cellular protection in times of heat stress to local climate cooling by encouraging clouds to form.

These findings have been published in the prestigious weekly science journal Nature.

Fewer rain storms across southern Australia

Published by CSIRO on 4 July 2011

Decreasing autumn and winter rainfall over southern Australia has been attributed to a 50-year decrease in the average intensity of storms in the region – a trend which is forecast to continue for another 50 years.”Our recent work on climate model projections suggests a continuation of these trends over the next 50 years.”

In an address today to the International Union of Geodesy and Geophysics conference in Melbourne, CSIRO climate scientist, Dr Jorgen Frederiksen, said these changes are due to reductions in the strength of the mid-latitude jet stream and changes in atmospheric temperatures. The jet stream comprises fast moving westerly winds in the upper atmosphere. [continue reading…]

Fire, carbon capture and the NT

Soil has the answer to burning climate questions


Decreasing the frequency of wild fires in northern Australia would lead to an increase in the amount of carbon stored in the soil, significantly lowering greenhouse gas emissions, according to CSIRO ecologist, Dr Anna Richards. [continue reading…]
