Modern attribution studies consistently show that human activities are making extreme weather events like heatwaves notably hotter and more intense.
Short human records do not fail to show trends.
Temperature and ice-core records prove the world is hotter than it has been in 125,000 years, with CO2 levels higher than anything seen in hundreds of thousands of years.
Heatwaves are not positive images for everyone to enjoy. Extreme heat poses severe health risks to vulnerable groups like the elderly, children, patients, and outdoor workers.
The belief that UK infrastructure can handle heat like hotter countries is false.
British homes and offices were built to retain warmth, lacking widespread air conditioning and shutters found in warmer climates.
Heat warnings are not unnecessary government overreach.
Warning systems save lives by prompting people to look after the vulnerable, drink water, and keep homes cool, lowering excess deaths since 2003.
The myth that CO2 increases agricultural yields as plant food is debunked. Real-world harvests are suffering globally due to intense dry periods, heatwaves, and altered rainfall patterns.
Finally, it is not too late for humans to act.

Because human actions caused the problem, achieving global net zero emissions can stabilize the climate and prevent heatwaves from getting worse.
