Bold visions for slowing global warming have emerged from all over the world. What’s not clear is how countries will meet them.

The Climate Change Committee has laid out a road map for net zero emissions that the UK government could follow.
Universities and the professions are changing in response to climate change. When will the advances in knowledge and practice we are already seeing prompt governments to act with the required urgency?
Heat pumps use electricity to transfer warmth from outside to inside a house.
Artificially dimming the sun, by injecting reflective particles into the upper atmosphere, could reduce the risk of Day Zero level droughts in Cape Town by more than 90% in the future.
Governments can align their policies to tackle both climate change and post-pandemic recovery.
If Canada began to reduce its greenhouse gas emissions by about four per cent per year, we could still meet our 2030 climate targets.
After four years of the US government undoing climate change policies and partnerships, a Biden administration has a chance to rebuild that leadership. But success will require more than quick wins.
A building designed to be easily taken apart so the components can be reused is a model for much less wasteful construction. It reduces resource use and environmental impacts, and can be cheaper too.
From property to local government, economic sectors are meeting the climate change challenge head on. Now the federal government must get on board.
Modern agriculture releases lots of different greenhouse gas emissions, each with complex effects on the global climate.
In dismissing the youth climate case, the court acknowledged that climate change is serious, but not serious enough to reconsider the reach of the constitution.
Is the UK government missing the wood for the trees?
Low-carbon energy sources aren’t all equally well-suited to getting us to net-zero emissions.
Green diesel may be intended to reduce emissions but it is not necessarily environmentally and socially sound.
Life cycle assessments of electric vehicles show that they cannot fully eliminate the greenhouse gas emissions of personal travel. We also need bikes, buses and trains to solve our climate problems.
Universities are vital hubs of research and teaching on climate change and, as big organisations, produce significant emissions themselves. They should therefore lead action to limit climate change.
Used in electrical switching equipment, sulfur hexafluoride (SF₆) has a global-warming impact 23,500 times higher than CO₂. New EU regulations seek to promote alternatives.
Similar arrangements already support the National Park Service, the National Institutes of Health and other federal agencies.
The Paris climate change agreement aims to limit global warming to 1.5C above pre-industrial temperatures — and the federal carbon pricing plan was meant to help Canada meet its commitments.
