To Limit Solar Geoengineering’s Side Effects, the Right “Dose” Is Needed.

Of the long list of strategies scientists have suggested to combat global warming, solar geoengineering may be among the most controversial.

We need the correct "dose" of geoengineering to limit side-effects.

At least in theory.

The idea is relatively simple: spraying reflective aerosols into the atmosphere to beam sunlight away from the planet and cool the climate. But some modeling studies suggest the strategy could cause unintended consequences, including effects on precipitation, hydrology, storms and other weather events.

Browned off: $90m 'clean coal' program ends as final project collapses

The last of a long list of government-backed "clean coal" projects has fallen over, with the Andrews government reluctantly confirming the end of a $90 million program announced amid much fanfare six years ago.

Latrobe Valley brown coal.

After days of pressing by The Age, Treasurer Tim Pallas’ department issued a statement announcing the conclusion of the joint federal and state Advanced Lignite Demonstration Program (ALDP) after the collapse of the program’s remaining scheme – a plan to turn Gippsland coal into char and oil by a company called Coal Energy Australia.

Mr Pallas refused to answer questions, instead leaving his department to handle media requests. Two other projects supported under the program had already failed.

The latest failed project did not receive any of the $90 million in government funding as it did not succeed in turning brown coal into clean fuel. It is not clear how much of that money has gone to any project.
