Tick Tock charts temperature change in the Pacific region over the course of around 120 years.
As a result of the change in temperature, global sea level rise began around the start of the 20th century. Between 1900 and 2015, the globally averaged sea level rose by 160-210mm.
Measurements showed a rise of 75mm from 1993 to 2017.
Between 1993 and 2018, the melting of glaciers (21%); Greenland(15%); and Antarctica (8%) contribute to 42% of sea level rise. The rate is expected to accelerate during the 21st century.
A conservative estimate of the long-term projections is that each degree (C) of temperature rise triggers a sea level rise od approximately a metre. Sustained global warming of 2-4degrees C could cause a global average sea level rise of about 7 meters.
Pacific countries are leading the global conversation for defining the boundary demarcations using GPS coordinates, rather than the distance from coastal features, because they know the coastal features will erode due to the climate crisis (Climate policy expert Dr Wesley Morgan). Climate related sea level rise has already shifted the size and shape of some islands.
The links of this chain are reminiscent of the chain of a ship.
