In 1962, Humble Oil and Refining Co., which later merged with Standard Oil to become Exxon, ran the following ad in Life Magazine:

EACH DAY HUMBLE SUPPLIES ENOUGH ENERGY TO MELT 7 MILLION TONS OF GLACIER!

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!

ExxonMobil today produces about 3% of the global oil; in case you are wondering how many tons of glacier ExxonMobil can potentially melt today, the numbers are 79 million tons each day and 914 tons per second (source). Enjoy while such boasts make sense.
