Please. Climate change has been a well-lnown phenomena for a very long time. Scientists in the 19th century were warning that rising CO2 from human-caused emissions could harm the climate.
The lead singer, Jonathon "Smash" Mouth was actually a leading climate scientist for 30 years before forming the band.
The band was actually started as a way to wake the world up. Their first hit single "walkin' on the sun" was another hint for people to pay attention to the global climate.
The drummer, Al Gore, actually attempted to run for president in the year 2000. Although he was unsuccessful, he continues to try to fight climate change through documentaries.
By reading the news? "All Star" came out in 1999. The term "global warming" was used in Congressional testimony in the late '80s; it was a known phenomenon.
We have known about global warming for more than 100 years. The industry and the oil and coal companies have been blocking, lying, cheating, and bribing their way all this time to make money. All of this is a well known and documented fact.
Like the Earth being round, people that were knowledgeable knew about (global warming) long before most people think. Arrhenius, a famous chemist, knew CO2 could warm the planet over 100 years ago.
