The climate crisis is not a distant threat. Every day, Médecins Sans Frontières/Doctors Without Borders witness the impacts of climate emergency on people's health. This testimony is just an example of it. People who already live in vulnerable settings are the most affected, even though they contribute the least to the problem. It is essential that the voices of those who already experience the consequences of the climate crisis are heard and placed at the center of decision-making. The climate crisis is about people. And it is also a health crisis.
