Whiter than white: could brightening clouds reduce symptoms of climate change?

Marine cloud brightening: it’s a concept that has been floated in climate engineering discussions for some time. But what are the moral implications of this geoengineering technology, and how likely is…

Earthquakes and mining - how humans create seismic activity

This week’s 5.3 magnitude earthquake that struck near Moe in Victoria’s brown-coal mining region of the La Trobe Valley brings to mind the 5.6 magnitude quake of 1989 in another coal-mining heartland…

Geoengineering trial cancelled: more regulation needed

Inventors have long been protecting their ideas by filing patent applications on new technologies. But is it appropriate for researchers or companies to own the intellectual property rights to climate-altering…
Geo-engineering should be a last resort; there are better steps we can take first.

Talking about geo-engineering may prevent us needing it

A lack of global action to combat climate change is forcing scientists to explore measures that might have been considered unethical a decade ago. With carbon dioxide emissions tracking at the high end…
A blimp-like balloon can be used to pump particles into the upper atmosphere.

Geo-engineering: why research something we never want to use?

What if the world left it too long to take action on global climate change? Is there a way we could somehow cool the planet before an environmental crisis occurs? Geo-engineering is a potential course…
