For most of our Earth’s history, carbon dioxide (CO₂) levels in the atmosphere have ranged between 180 and 280 parts per million (ppm).
When CO₂ levels were around 280 ppm, the corresponding Earth temperature could sustain life. When CO₂ levels were around 180 ppm, (it was) times of ice ages.
For the first time in the history of Earth, CO₂ reached 300 ppm in 1950 (Editor: the first time was between 1900 and 1910 during the Industrial Revolution). Today, CO₂ levels have reached 425 ppm. A 42% increase in just 75 years! An unheard-of rate of change to a level our world has never experienced.
Carbon dioxide in the Earth’s atmosphere acts like a blanket, holding heat in and preventing it from being released back into space. The more the CO₂, the thicker the blanket. The thicker the blanket, the warmer our world gets.
And just like being under a blanket, it takes a while to warm up. Earth has just gotten under the blanket, and temperatures have just started to rise.
It is very clear; as the species that is killing our planet, we must be the ones to save it. Please take action today. Our world needs you.
