Over the past 100 years, we have emitted more and more co2 into the atmosphere year by year. Co2 is emitted when we burn fossil fuels such as coal, oil, natural gas and wood.
The more co2 that is released into the atmosphere, the more it rises
the temperature of the globe.
The temperature rise is already about 1.5 degrees Celsius
and it will probably be 3 degrees in a few years.
This means even more drought and even bigger floods. Larger parts of the globe will become uninhabitable.
Politicians and decision-makers know how co2 is released
is stopped. But unfortunately you are far behind in most places
with climate-correct actions.
