OVER Global Warming.

TURN DOWN. SWITCH OFF. RECYCLE. WALK. CHANGE

The Earth's climate has changed many times during the planet's history, with events ranging from ice ages to long periods of warmth. Historically, natural factors such as volcanic eruptions, changes in the Earth's orbit, and the amount of energy released from the Sun have affected the Earth's climate. Beginning late in the 18th century, human activities associated with the Industrial Revolution have also changed the composition of the atmosphere and therefore very likely are influencing the Earth's climate.

El clima siempre ha variado, el problema del cambio climático es que en el último siglo el ritmo de estas variaciones se ha acelerado de manera anómala, a tal grado que afecta ya la vida planetaria . Al buscar la causa de esta aceleración, algunos científicos encontraron que existe una relación directa entre el calentamiento global o cambio climático y el aumento de las emisiones de gases de efecto invernadero (GEI), provocado principalmente por las sociedades industrializadas.
