El tratado de París sobre el Cambio Climático no garantizaría que no ocurrieran efectos catastróficos para el planeta

En un artículo en Real Climate, un blog de los científicos del cambio climático mas respetados del mundo nos dicen que no solo tenemos que bajar las emisiones de gases invernaderos sino que estas tienen que empezar a bajar para el 2020.

Why global emissions must peak by 2020

Not only will these impacts get progressively worse as warming continues, but our planet also runs a growing risk of crossing critical tipping points where major and largely irreversible changes to the Earthsystem are triggered (see Fig. 1- ver Featured image).

Fig. 1 Tipping elements in the Earth system, in relation to past global temperature evolution since the last Ice Age 20,000 years ago as well as future warming scenarios[iii]. The Paris range of 1.5 – 2 °C warming is shown in grey; the bars show increasing risk of crossing tipping points from yellow to red.
