Scientists have long warned that climate change will lead to more intense weather, such as heatwaves, floods and cyclones.
Many point to record-breaking temperatures now in India and Pakistan as proof.
Although heatwaves are common in the region, they do not usually start until May or June.
The intense heat has increased demand for electricity, leading to power outages.
Both countries rely mainly on fossil fuels, especially coal.
The UN’s Intergovernmental Panel on Climate Change says India must drastically cut greenhouse gas emissions to avoid devastating weather events.
So what can be done to reduce the impact of the heatwaves?
