The Supreme Court recently dealt defeat to Florida in its 20-year legal battle with Georgia over river water. Other interstate water contests loom, but there are no sure winners in these lawsuits.
Russia is attempting to claim more of the Arctic seabed, an area rich in oil, gas and minerals. It’s also expanding shipping and reopening Arctic bases. Here are two things the U.S. can do about it.
Australia must treble its emissions reduction targets and reach net-zero emissions by 2035. Without this and other radical global action, the chance to hold warming to well below 2°C will pass us by.
It’s meant to stop what’s known as ‘carbon leakage’ – when production moves elsewhere to avoid climate policies – but the solution has economic, legal and environmental consequences.
A new report from the Australian Strategic Policy Institute says the federal government has overlooked the national security threats of climate change.
Electricity emissions can be cut to net-zero while keeping the lights on and prices down. But achieving that quickly means keeping gas around, for now.
Scientists are learning trees can emit methane, which could be a big problem for global warming. But a world-first discovery of methane-eating bacteria in paperbark can help moderate this.
Peatlands store more soil carbon than any other terrestrial ecosystem, including tropical forests. But they have been heavily exploited and damaged. Now, scientists are working to restore them.
Climate change has already made tropical oceans too hot for some marine species to survive. As they flee towards the poles, the implications for ecosystems and human livelihoods will be profound.
