Rather than just a small change here or there, taking real action on climate change and biodiversity requires a fundamental, system-wide reorganisation.
Climate change is a serious threat now for poor people in developing countries, but the COP24 conference in Poland offered them little hope of near-term emissions cuts or economic aid.
An economist breaks down results on two key issues at the COP24 climate change meeting: getting all nations to use the same measuring and reporting rules, and linking policies across borders.
Three years after the Paris Agreement, negotiators have finally agreed (most of) the rules for its implementation. But there is still no way to compel countries to deepen their climate ambitions.
For decades, economists have pondered the ‘social cost of carbon’ - the price worth paying to avoid the future costs of greenhouse emissions. But a new analysis suggests this quest is impossibly complex.
Thirty percent of global emissions will be generated from democracies governed by populist nationalist leaders who have very different playbooks than more traditional politicians.
The Paris Agreement was a breakthrough in global climate talks, but nations now face major hurdles to meeting long-term emissions goals – and maintaining global support for the deal.
We may only have 12 years to stop climate change and the landmark Paris Agreement of 2015 seems more in doubt than ever. What can we hope to come out of COP24?
While the world gathers to negotiate on climate change, governments must recognise the public desire for action on plastic pollution and work together to solve it.
Private finance crashed the economy and is too consumed by the profit motive to be a reliable ally against climate change. We should not allow COP24 to be their board meeting.
