Children running after ice cream vans in the 1960s were often handed tiny nuggets of dry ice to pop into their mouths, where it bubbled and fizzed. They were unaware of possible ice burns. Dry ice is the solid form of CO₂. It is used as a crucial industrial coolant, maintaining an icy temperature of -78.5C. Because it sublimes directly from solid to gas without melting into liquid, it leaves no wet mess behind. CO₂ was recognised for its use in refrigeration, fire suppression and beverage carbonation. This unique property makes it invaluable for preserving frozen foods, shipping meats and ice cream, and safely transporting temperature-sensitive vaccines, blood samples and biological tissues. CO₂ remains an indispensable global substance, driving photosynthesis, supporting the basis of all life, and the primary driver of biology. However, it was included in the rise of modern climate rhetoric. Recent warming has been remarkably modest. Average global temperatures have risen only 1.4C in the 250 years since the start of the Industrial Revolution, following the end of the Little Ice Age. The calculated global average temperature of 15C remains several degrees colder than long-term historical biological baselines of 18C-26C. From a childhood treat beside an ice cream van to a foundational industrial workhorse, CO₂ has spent far more time serving humanity than being a villain.
