dibujos animados sobre el cambio climático

He encontrado un bonito video sobre el cambio climático.
Con dibujos animados el video habla del punto de no retorno, los mecanismos de retro-alimentación y otros temas relacionados con el cambio climático.

Por supuesto, un tema científico tan complejo es difícil de explicar y muchas hipótesis ó suposiciones no se mencionan. Las consecuencias que se presentan en el video no son fáciles de sacar … y pueden ser erroneas … pero una buena gestión de los riesgos nos debería llevar por el camino de la prudencia.

El clima de la tierra es un animal complicado y no lineal. Y cuando digo no lineal me refiero a lo siguiente. Un fenómeno lineal implica que cambiar una variable (digamos la presión) resulta en un cambio proporcional de otra magnitud (digamos la temperatura). Así, subir un poquito la presión sube un poquito la temperatura. Pero cuando un fenómeno es altamente no lineal es mucho más difícil hacer predicciones certeras … Subir un poquito la presión puede subir un poco la temperatura, pero un pelín más de presión podría precipitar una caida y luego una remontada brusca de la temperatura … y esos fenómenos inesperados son típicos de sistemas complejos no lineales.

Por supuesto hay herramientas matemáticas para describir estos complicados procesos … pero son rudimentarias. Y también encuentran sus límites en la fiabilidad de los datos y las medidas. Aún así, aunque no haya mucha certeza respecto al clima, es recomendable informarse y tomar una posición de prudencia activa: Reducir el consumo de energía y bienes (ó en su defecto consumir de manera más eficiente) sin duda puede ayudarnos a ganar tiempo para entender mejor este sistema recalentado que es el ecosistema de la tierra!
