Earth’s atmosphere made life as we know it possible on Earth with just the right amount of heat, energy, and stability for us to exist and progress. Today’s Earth average temperature is 16°C and Green Houses Gases (GHG) are vital for our existence on this planet otherwise at -18°C life would not have existed as we know it today.
Too much GHGs are extremely dangerous because they keep trapped the energy that comes from the sun, determining the Earth temperature to increase too much. Just as a tasty pie, we need the right temperature, not too cold and not too hot and right now our house is on fire.
In the last 120 years, GHG increased by 1750%, from 2 billions tonnes of CO2 in 1900 to an outstanding 37 billions tonnes of CO2 in 2017. We have 1°C remaining on the global warming budget, but we are now on the road to a 4°C temperature increase. If that doesn’t seem much, remember that today it is just 4-7°C hotter than 11,300 years ago, when the end of the last ice age happened — more info on NASA’s website.
In 2015, almost 200 countries around the world agreed and signed the Paris Agreement at COP21 to limit the global warming by 2°C in report with pre-industrial levels, but we are not moving fast enough. Global warming doesn’t mean longer summer parties and fewer places for skiing, climate change is currently the world’s biggest threat facing humanity, according to both to United Nations and World Economic Forum and we are about 11 years away from being in a position where we set off an irreversible chain reaction beyond human control (IPCC report).
