Direct experience of climate impacts is thought to increase concern about climate change. New survey data provide empirical evidence that those who have experienced flooding tend to feel more concern and perceive less uncertainty about climate change, and have greater willingness to change behaviour to save energy.
An analysis of over 20,000 historical African maize trials suggests the crop will better cope with climate change under rain-fed management. For a 1 °C temperature rise, optimal rain-fed conditions would mean 65% of maize-growing areas in Africa would be likely to experience yield losses, compared with 100% under drought conditions.
