What is global warming and what is its main consequence?
Global warming is the increase of average temperatures on Earth (about 1°C), caused by massive industrial activity since the 19th century. 1°C does not seem like a large increase, but it actually represents a big disruption in global atmospheric and oceanic cycles, and causes a significant sea-level rise
Projections of global warming in the future are very alarming. That is why many countries, like Singapore, have accepted to reduce their greenhouse gases emissions on the long-term.
