Australia was a different place in 2011. Julia Gillard’s Labor government, the Greens and a couple of country independents were rewriting the country’s climate policies, including introducing a world-leading carbon pricing system and creating three agencies to back it up.

Those organisations – the Clean Energy Finance Corporation, the Australian Renewable Energy Agency and the Climate Change Authority – have survived and help shape the investment and policy landscape. The carbon pricing system – falsely described as a tax – famously didn’t.

Natural gas will remain important to bridge the gap in energy demand for "many decades" as the US grid expects greater additions of solar and wind power, but carbon capture technology is not yet commercially competitive, according to a study published Monday by a US public policy think tank.

Bethany Beach firefly, found in Delaware, Maryland and Virginia, faces dangers to habitat because of climate change

The US government is seeking to consider a firefly species as endangered for the first time, according to a proposal from the US Fish and Wildlife Service.

The Bethany Beach firefly, found in coastal Delaware, Maryland and Virginia, is facing increasing dangers to its natural habitat because of climate change-related events. They include sea level rise, which is predicted to affect all sites within the known distribution by the end of the century, and the lowering of groundwater aquifers.
