With global warming, temperatures rise in the summer periods, and with that in regions where there are water sources, there is a strong evaporation, and with that a heavy rain, causing disasters like what happened in Germany.
But in regions with little water reserve there are droughts, and with that there are forest fires, as occurred in the United States, Canada and Russia.
In the southern part of the planet, winds cool the region at the cost of melting glaciers, to cool the planet.
But chaos doesn't end like that. All regions are losing the volume of water in their rivers, harming both the energy supply and the source of water for drinking and planting.
Costs increase, and the living system becomes more expensive. Countries are looking for more energy in thermal power plants, throwing carbon dioxide into the atmosphere, and increasing the planet's temperature. And this cycle is increasing, until life on the planet becomes unsustainable.
Countries are always against uniting, and you don't see that this will happen. What remains is a negative view of the future, with a drop in life expectancy, and overall quality.
As we are already seeing today, with the catastrophes coming from global warming. There is no way to deceive anymore, and now countries are just trying to change the subject, but eventually it will no longer be possible.
