Billionaires get it. A million households get it. And so do thousands of businesses. So why does Australia's government - and its principal regulators - fail to understand that the way to a cheaper, cleaner and more reliable grid is with more renewables, not less.

Sudden jump in shipping rates from China to Australia is adding 20-30% to costs of suppliers to Australian wind and solar developments.

A web-based interactive map – dubbed the Uber of the electricity market - will help pave the way for a smart and renewable grid.

Fatal shark bites are very rare. But the stats do suggest that the likelihood of an attack proving fatal is higher in Australia - probably because our waters are home to the "big three" dangerous species.

Peruvian lawsuit in London claims Xstrata should be liable for alleged police violence against demonstrators near Tintaya mine

A UK-registered mining company, which is now part of Glencore, is facing claims in a London court that it hired security forces to mistreat environmental activists protesting about a copper mine in Peru.

Caritas says thousands face threats to their wellbeing, livelihoods and ‘their very existence’ due to rising sea levels

Pacific Islanders whose homes face eradication by rising sea levels have called on Australia to not fund the Adani Carmichael coalmine, as a new report reveals the worsening impact of climate change across Oceania.

Residents of the endangered islands have described their forced displacement as like “having your heart ripped out of your chest” as they called on the Australian government to do more to combat climate change.

Algal blooms, hurricanes and volcano fields are among the images captured by Nasa and the ESA last month

A potentially harmful algal bloom covered more than 700 square miles in the western basin of Lake Erie in late September, turning the lake bright green and alarming residents and local officials. Blooms tend to thrive in Lake Erie during summer, sustained by warm water temperatures and nutrients from farm runoff. This year, the bloom had been ongoing since mid-July.

Report reveals large gap between government pledges and the reductions needed to prevent dangerous global warming

There is still a large gap between the pledges by governments to cut greenhouse gas emissions and the reductions scientists say are needed to avoid dangerous levels of climate change, the UN has said.

Current plans from national governments, and pledges made by private sector companies and local authorities across the world, would lead to temperature rises of as much as 3C or more by the end of this century, far outstripping the goal set under the 2015 Paris agreement to hold warming to 2C or less, which scientists say is the limit of safety.

Río Almonte, Extremadura, Spain Camel-haired legs, gleaming black eyes and the largest pair of spider jaws you’ve seen in your life – a tarantula

There were all sorts of exciting birds overhead, including vultures in elegant spirals and clusters of crag martins spooked up by a hunting sparrowhawk. Yet the group’s attention had been called to an insignificant hole in the bare ground by the picnic table.

The hole was 4cm across and had an untidy circlet of dead grasses arranged in a silk-knotted perimeter. By sheer chance I had just read about the occupant and how it could be lured into view with a grass stem drooped into the burrow entrance like a fishing line. Sure enough, within seconds, book learning was turned into startling experience.
