This post explores the extent to which Global Warming poses a threat to continued social and economic development.
According to the latest data from Climate.gov global warming is currently causing sea levels to rise by 0.3 centimetres a year, which means that sea levels may have risen by up to 2.5 metres by 2100.
A recent report by Climate Central (2019) suggests that 300 million people live in areas that will be subject to severe flooding due to climate change, China and Bangladesh have the most people living in at-risk areas.
The Polynesian Island of Tuvalu, population 11 000, is on the frontline of Sea Level Rise – located in the Pacific Ocean this is a thin slip of an Island where the residents are now struggling to survive because of rising sea levels. This Guardian article (2019) takes an in-depth look the problems the residents face. There is a very real chance all of these people could end up being climate change refugees within the next decade. NB the United Nations is aware of their plight, but it’s difficult to see what we can do that is practical.
This documentary from 60 Minutes Australia (2019) explores the rapid disappearance of parts of the Solomon Islands, where sea levels have increased by up to 15 centimetres in the last 20 years:
From a research methods perspective this is interesting as one researcher used old photos to compare where some of the islands used to be compared to their reduced sizes today; and there are also interviews with people who grew up on the islands – some of the places they used to picnic as kids are now gone forever, completely under water!
The Global Climate Risk Index is a useful broader source than the above – it focuses more on all extreme weather events, so not just flooding (also droughts and extreme weather events).
NB – just to reiterate that the latest modelling suggests that if anything sea levels are rising FASTER than previously projected, so these problems are set to get worse!
