Under the scheme, power companies would have twin obligations imposed on them by the government.

How the Great Barrier Reef can be helped to help repair the damaged reef.
Corals on the Great Barrier Reef that are tolerant to warmer waters can be used to help repair other parts of the reef damaged by recent coral bleaching events.
Climate change could severely impact the world’s coffee-producing nations and turn a cup of decent java into a luxury in the years to come.
By 2100, more than 50 per cent of the land now used to grow coffee will no longer be arable. Climate change is changing the game to such an extent that Canada could one day become a coffee producer.
Leaping bottlenose dolphins.
The dolphin population in parts of Western Australia more than halved one year, just as an El Niño event hit over in the Pacific. So what's the connection?
Each year satellite images and maps show patterns linked to land use/cover change.
A new approach to monitor changes to the earth's surface uses maps that consist of physical and human geographic data to explain what's changed.

A nuclear blast and runaway climate change could propel us into the Plutocene.
Imagine a world ravaged by the fallout from nuclear weapons and the runaway effects of climate change. Congratulations, you've just imagined the Plutocene, but let's hope it doesn't become a reality.
