The tropics are the dominant player in the global climate system. Just a few decades ago, meteorological research was focussed on mid-latitude circulation with the tropics receiving little attention. However recent research, particularly around the El Niño-Southern Oscillation (ENSO) phenomenon has altered our view of global climate. We know now that ENSO is the largest single source of global climate variability. What is important here is that ENSO events are predictable. This has enormous societal benefit as forecasts allow climate- vulnerable regions time to prepare for adverse environmental conditions.
- Myanmar has the world’s fastest growth rate: between 2010 and 2013, mobile phone use increased by more than 1000%
- Mobile phone use in Somalia grew by more than 600%
- There are 30% more mobile phones in the Tropics than there were in 2010
- There are now more mobile phones than people in Mali and Cambodia, with both nations growing from just over 50% to around 130% in 2013
- The proportion of people with mobile phone subscriptions increased from under 70% to more than 85% in the Tropics
- Globally in 2013 it was estimated that almost 30% of these subscriptions were for smartphones – a proportion expected to be 50% by 2016 and more than 80% by 2020
- Internet use in 2013 still trailed mobile phone use in the Tropics at only 24%, however there’s been a 54% increase since 2010
