In the late 1800’s scientists were already starting to question how emissions from CO2 could affect our planet. In 1896 the Swedish scientist Svante Arrhenius published an idea; by burning fossil fuels such as coal, thus adding CO2 to Earth’s atmosphere, humanity would raise the planet’s average temperature. This “greenhouse effect,” as it later came to be called, was only one of many theories about climate change at the time. Most people thought that humanity could never affect the vast global climate cycles, which were governed by a benign “balance of nature.” 

Fast forward to the present day: CO2 levels are now higher than they have ever been in mankind’s history. 

The last time Global CO2 was over 400ppm was the era known as the Pliocene – 3 – 5 million years ago! The sea level was five to 40 meters higher than today and the North and South poles were 10 degrees Celsius hotter than today.
