Rising sea levels continue to be a cause for concern. Using new techniques to measure ice in the world’s polar regions, a group of experts has calculated that the seas on our planet could rise by two meters by 2100, an increase essentially due to the melting of the polar ice. This is an increase in sea level which would literally mean flooding coastal cities like New York.
The main author of this new study, Jonathan Bamber of the University of Bristol in the UK, clearly states that a sea-level rise of more than two meters cannot be ruled out if we continue along today’s trajectory of emissions, essentially those caused by the burning of fossil fuels, which cause global warming through increased CO2 in the atmosphere.
This trajectory predicts an increase of 5°C in the average global temperature, one of the worst scenarios, substantially the one that would occur if the situation were to remain as it is today and if no counteracting action were to be taken by world governments in the coming years.
Such an increase would lead to a loss of land of about 1,200,000 square miles, an area equivalent to three times that of California. Not only New York and Miami would be flooded, but also other cities such as London and Rio de Janeiro, situations that would involve almost 200 million people in the world who would then have to be moved elsewhere, with more than harmful consequences for humanity, especially from an economic point of view.
This assessment is twice as high as other assessments recently presented by other experts. And the study’s projections go even further even though uncertainty about the forecasts naturally increases exponentially. In the worst-case scenario, sea levels could rise by as much as 7.5 meters by 2200.
