Back in the 1960's, having the engergy capacity to melt glaciers was something to brag about. But today, with climate change, no oil company would use melting glaciers in their advertising campaign. This ad appeared in Life magazine in 1962.
"The giant glacier has remained unmelted for centuries. Yet the petroleum energy Humble supplies -- if converted into heat -- could melt it at the rate of 80 tons each second. To meet the nation's growing energy needs for energy, Humble has applied science to nature's resources to become America's Leading Energy Company. Working wonders with oil through research Humble provides energy in many forms -- to help heat our homes, power our transportation, and to furnish industry with a great variety of versatile chemicals. Stop at a Humble station for new Enco Extra gasoline, and see why the "Happy Motoring" Sign is the World's First Choice!"
Humble Oil (started in Humble, Texas) eventually became Exxon Mobil. Today it extracts enough oil to melt 914 tons per second.
