A major report released this week by the Intergovernmental Panel on Climate Change, involving scientists from around the world, gauges the world’s progress so far at stopping climate change. The sobering assessment presents a definitive assessment of how well the world is doing in finding solutions to rising temperatures.
Leading academics who contributed expertise to the report unpack key aspects of its findings, and what they mean for the world.
The report also points to innovations that have the potential to transform the world for a safer future. This includes four powerful trends in transportation that could greatly reduce the sector’s greenhouse gas emissions – three of them involving human choices and behaviour.
Ukrainians continue to flee to neighbouring countries as Russia’s deadly war pushes into its second month. The number of refugees, mostly women and children, now surpasses 4 million. This new refugee population feeds into an ever-growing number of people who are displaced from their homes worldwide because of conflict and climate disasters.
As is the case for tens of millions of refugees, returning to the place once known as home may become increasingly challenging for Ukrainians as time passes, writes post-conflict migration scholar Sandra Joireman.

Even once the war in Ukraine ends, the millions of people who fled from their homes might not be quick to return. The faster the war ends, the more likely it is they will go back.
