The US, a minor liquefied natural gas supplier a decade ago, now is the world’s top source. That’s good for energy security, but bad for Earth’s climate. An energy scholar explains the trade-offs.
We don’t yet fully understand what global climate tipping points mean for Australia. But we know enough to conclude the impacts of passing one or more tipping points must now be considered.
Without urgent action, Earth is heading for climate catastrophe. Yet there are reasons for hope in 2024 – including a possible peak in global greenhouse gas emissions.
A study of dozens of city gardens and urban farms across the US and Europe found several ways to boost their benefits, not just for their neighborhoods, but for the planet.
Looking to go solar? While small-scale solar delivers the best results with the least life-cycle impact, a mixed approach offers the best long-term path towards an all-electric future.
The UN climate conference brought some progress. A former UN official who has been involved in international climate policy for years explains what has to happen now for that progress to pay off.
The most comprehensive Australian carbon budget assessment completed to date shows the nation flip-flops from source to sink of carbon emissions, depending on the prevailing conditions.
Carbon pricing can be a powerful tool to combat climate change and reduce emissions, but it needs to be accompanied by improved regulations, clean technology subsidies and financing mechanisms.
Current greenhouse gas inventories in Canada only consider “managed” lands. This must change before we can truly understand the scale of Canada’s carbon emissions.
It might seem counterintuitive to suggest timber harvesting when the goal is to restore forests, but that gives landholders the economic incentive to protect and manage forests over time.
The deal is a global aspiration, not a legally binding agreement. But it should end the idea that burning carbon – in Australia and elsewhere – can continue on a significant scale beyond 2050.
