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.
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.
The US saw a record number of billion-dollar disasters in 2023, even when accounting for inflation. The number of long-running heat waves like the Southwest experienced is also rising.
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.
The proliferation of Antarctic research stations – 77 in all – is increasing knowledge of the continent but also the human impacts. A new study has identified the best ways to limit these impacts.
Does the science support the need for a fossil fuel phase out to reach 1.5 C? The answer depends on whether we believe that carbon capture and removal technologies can be deployed safely at scale.
Embracing hope in the good, alongside recognizing the bad, can reduce eco-anxiety, improve mental health and may just be the key to driving strong and meaningful climate action.
As Climate Change and Energy Minister Chris Bowen lands in Dubai for COP28, Australia has announced an extra A$150 in climate finance with a focus on the Pacific region.
Carbon capture and sequestration can play a role in limiting warming but the nuances of its application are far more complicated than just planting trees. Getting it wrong could make warming worse.

The agreement still leaves many unanswered questions, as well as concerns from vulnerable countries about who will qualify, who pays and who is in charge.
