This brochure summarises the current and expected future climate in Tonga, based on the latest emissions scenarios and climate models.

It updates the original Current and future climate of Tonga brochure published in 2011 (available in both English and Tongan).

The content of this brochure is the result of a collaborative effort between the Tonga Meteorological Service and the Pacific-Australia Climate Change Science and Adaptation Planning (PACCSAP) Program – a component of the Australian Government’s International Climate Change Adaptation Initiative. The information in this publication, and research conducted by PACCSAP, builds on the findings of the 2013 IPCC Fifth Assessment Report, and uses new emissions scenarios and climate models.

There are 14 country-specific information brochures available for the Pacific region, accessible via the Pacific Climate Change Portal.
