Pregunta:\u00a0 \u00bfQu\u00e9 es la ciencia detr\u00e1s del calentamiento global? <\/strong><\/h2>\n

Respuesta:<\/strong> La tierra recibe calor del sol, y normalmente env\u00eda una cantidad igual al espacio en la forma de radiaci\u00f3n infrarroja. Ciertos gases \u2013 \u201cgases de efecto invernadero\u201d \u2013 interceptan una porci\u00f3n de esta radiaci\u00f3n saliente y as\u00ed mantienen la temperatura m\u00e1s alta que ser\u00eda sin ellos. El di\u00f3xido de carbono, CO2<\/sub>, es el m\u00e1s importante de estos gases. Si no hubiera nada de CO2<\/sub> en la atm\u00f3sfera, nos congelar\u00edamos todos, pero solo un poquito es suficiente para sostener la vida.<\/p>\n

Por aproximadamente 10,000 a\u00f1os, ese nivel de CO2<\/sub> era bien constante, d\u00e1ndonos un clima estable donde vivir y crecer. Pero cuando descubrimos el carb\u00f3n, petr\u00f3leo y gas natural y todas las cosas que podr\u00edamos extraer con ellos, empezamos de quemarlos cada vez m\u00e1s. Quemar esos combustibles convierte el carbono “f\u00f3sil” que ha estado enterrado debajo la tierra para millones de a\u00f1os a CO2<\/sub>, pasando el nivel natural que ten\u00edamos para los milenios.<\/p>\n

Los cient\u00edficos descubrieron el efecto invernadero en los a\u00f1os 1850 [1<\/a>,2<\/a>], pero no era hasta 1958 que pod\u00edamos medir exactamente la cantidad de CO2<\/sub> en el aire y monitorizar su velocidad de aumenta. [3<\/a>] Solamente en ese tiempo, ha subido por m\u00e1s que 30 por ciento [<\/span>4<\/span><\/a><\/u><\/span>]<\/span>, aproximadamente cien veces m\u00e1s r\u00e1pido que se pudiera explicar un ciclo natural. [<\/span>5<\/span><\/a><\/u><\/span>]<\/span><\/p>\n

Eso no solamente est\u00e1 aumentando la temperatura global, sino que casi la mitad del CO2<\/sub> exceso entra en los oc\u00e9anos, acidificando el agua, que es da\u00f1ino a la importante vida marina. [6<\/a>]<\/p>\n

La actividad humana, mayormente la quemadura de combustibles f\u00f3siles, actualmente agrega m\u00e1s de 1,000 toneladas de CO2<\/sub> cada segundo<\/em> a la atm\u00f3sfera y los oc\u00e9anos. [7<\/a>]\u00a0 Los ciclos naturales, los volcanes, y el sol han sido descartadas como causas del aumento de la temperatura actual. [8<\/a>] O son muy peque\u00f1as, o muy lentas, o van en la direcci\u00f3n opuesta. La causa somos nosotros.<\/p>\n[\/spb_text_block] [spb_message color=”alert-info” width=”1\/1″ el_position=”first last”]\n

En pocas palabras:<\/strong> Las temperaturas globales est\u00e1n aumentando a un ritmo gradual pero acelerando. Esto se debe en su totalidad a la acumulaci\u00f3n de gases de efecto invernadero causada por la actividad humana, principalmente la quema de los combustibles f\u00f3siles.<\/p>\n[\/spb_message] [divider type=”standard” text=”Go to top” full_width=”no” width=”1\/1″ el_position=”first last”] [fullwidth_text alt_background=”none” width=”1\/1″ el_position=”first last”]\n
