Most Africans place primary responsibility for climate action on their own government. Our new paper in @natureportfolio.nature.com shows a further third see ordinary citizens as most responsible, while very few place responsibility on historical emitters that caused the climate crisis.
Comparison of proportion of respondents in each country who have heard of climate change and believe the actor most responsible for limiting climate change is their own government, ordinary Africans, rich countries, or industry.

Southern California now sees longer fire weather seasons, like many other places worldwide Human-caused climate change means hot, dry, windy conditions happen more often, priming landscapes to burn more easily if ignition occurs Matt Jones et al 2022 agupubs.onlinelibrary.wiley.com/doi/10.1029/...
Map of global land showing gridded data of changes in Fire Weather Season Length, with increases of over 40 days per year in south-western North America, much of South America, eastern and southern Africa, south-eastern Europe and central and eastern Australia.
