Scientists now have a better understanding of the risks ahead and a new early warning signal to watch for.
Crowds gather at the Saturday market in Lalibela, Ethiopia in 2019. Sub-Saharan Africa’s population is growing three times faster than the global average.
Environmental policymakers and scholars must listen to sub-Saharan Africans’ voices and recognize the importance of population for achieving sustainable development goals.
Keeping the average global temperature rise below 1.5°C since pre-industrial times is a goal of the 2015 Paris climate deal. New research suggests that opportunity has passed.
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.

Australians want government to act on climate change, but not necessarily now, or in their neighbourhood. How can governments resolve this dilemma?
Infrastructure can increase vulnerabilities to coastal cities like New York.
Land subsidence is a factor as preparations are made for rising sea levels and strengthening storms. Human infrastructure, including buildings and groundwater extraction, increases vulnerabilities.
