News: Last week saw global average daily temperatures in a range never seen before. Last Monday, it reached above 17 degrees Celsius. This was the hottest day recorded in history. The record was beaten again on Tuesday, and then on Thursday. More records are expected to be broken in the coming days and weeks. 2023 is likely to be one of the hottest years ever.

How is climate change progressing?

Climate change is happening as predicted by scientists, but maybe a bit faster. It’s not just heat, but also heavy rain, floods, droughts, and wildfires. While these cannot be stopped instantly, governments can act to reduce their impact.

What can be done to tackle heat waves?

Simple interventions can significantly reduce deaths from heat waves. However, many local governments don’t have a heat action plan. No area can consider itself safe from heat waves due to their unpredictable nature.

How has heat wave exposure increased over the years?

In 2015, nine states experienced heat waves. By 2020, 23 states were affected. The number of heat wave days per year increased from seven in 2015 to 33 in 2020. Last month, eastern UP saw many people hospitalized, and several died due to heat-related diseases. These are the shocks that may repeat if local governments are not prepared.

Why heat waves in the rainy season?

It may seem strange to discuss heat waves during the rainy season. However, July is one of the four months when heat waves are expected. Recent trends suggest that heat waves could occur in subsequent months as well. Therefore, it’s an ideal time for local governments to prepare for heat emergencies.
