Most heat-related deaths would occur in high-income countries and in South and
East Asia, and most under-nutrition-related deaths among children would occur in
sub-Saharan Africa and in south Asia, as per the WHO report.
While the estimate of climate-related deaths represents a substantial reduction
in the progress towards greater food and nutrition security that is projected to
occur until 2050, the sensitivity analysis suggests that climate change
mitigation could greatly reduce the number of climate-related deaths.
Strengthening of public health programmes aimed at preventing and treating diet
and weight-related risk factors could be a suitable climate change adaptation
strategy, suggests the Lancet study with the hope that “Adoption of
climate-stabilisation pathways would reduce the number of climate-related deaths
by a rate between 29% and 71%, depending on their stringency.”
