CSIR researchers argue for global carbon observation system CSIR climate scientists are advocating the establishment of a global carbon observation system to deliver more accurate and standardised information on carbon flux in the oceans, atmosphere and land.

CSIR researcher asks for immediate alternatives to sand-mining Sand-mining in the estuaries and riverine sections of Durban's rivers will have a dramatic effect on coastal erosion if alternative sources are not found soon. Combined with climate change, the consequences to KwaZulu-Natal's golden beaches could be similar to and eventually far exceed the erosion suffered in 2007.

Lichens used as bio-indicators of atmospheric heavy metal pollution A CSIR-study determined levels of heavy metals, specifically manganese and lead, in lichens growing on trees in Pretoria.

Scenarios play an important role in strategising for the future Scenario planning for the future plays an important part in helping policy-makers and other stakeholders to develop strategies that will lead towards a desired future.

Landmark workshop maps the way forward for climate change atlas Researchers and decision-makers from various government sectors concerned with global and climate change met in Pretoria recently for a landmark workshop aimed at bridging the gap between global change science and global change policy.
