A new study in the densely populated city of Dhaka has found that people's knowledge, attitudes, and behaviors towards climate change are closely linked to their level of education and income. The researchers found that those with higher education levels and higher incomes were more likely to have a better understanding of climate change and take steps to adapt to its effects, such as reducing their risk of heart disease. The study also highlighted the need for targeted education and support for vulnerable groups, such as those with pre-existing health conditions, to help them build resilience to climate change.
