Im a fairly novice guitarist but I love this song and just had to find a way to play it.
So if you are like me I think you will find most of this pretty satisfying to strum and 
sing through.

I welcome any elaborations mainly to the start and end

Desastre Natural

F
Hoy es un d?a cuando un simple beso
           F                         Am
resolver?a todo, hacernos olvidar

               G           Bb         F         Dm
el rio se ha secado y esto no es un examen
                      Am           Bb         F         Gm
por ese agujero en mi cielo y esto no es un examen
                  C                Gm                 E         Am
nuestros campos y bosques est?n en llamas de arrepentimiento
                 G             Bb         F
y a nadie has de culpar y esto no es un examen

                    G           Bb         F         Dm
los volcanes soplan alto y esto no es un examen
                  Am           Bb         F         Gm
tu tierra sudar? rencor y esto no es un examen
              C           Gm                E         Am
la marea no latira con verg?enza y arrepentimiento
                 G             Bb         F
y a nadie has de culpar y esto no es un examen

es el final..


Translation

Today is a day when a simple kiss
would resolve everything and make us forget.

The river has dried and this is not a test
through that hole in my sky and this is not a test.
Our fields and forests are in flames of repentance
and you mustn?t blame anyone and this is not a test.

Volcanoes blow high and this is not a test.
Your land will sweat rancor and this is not a test.
The tide won't beat with shame and repentance
and you mustn?t blame anybody and this is not a test.

This is the end..
