Flooded Earth: How the global map and countries' coastlines will change by 2100 as higher temperatures cause sea levels to rise, flooding cities such as London and New York Current projections show global temperatures are set to rise to as high as 3.1 degrees Celsius by 2100 This would be a disaster for millions, causing extreme heat waves, rising sea levels and mass migration Meanwhile, a recent UN report found there was 'no credible pathway' to halting temperature rises at 1.5C As a result, rising sea levels by 2100 are already inevitable.
