If global temperatures rise above 1.5° Celsius above pre-industrial levels—the ideal temperature limit set by the Paris agreement—global sea levels will rise by more than 40 centimeters (approximately 15.7 inches) by 2100. If temperatures top 2° Celsius, sea level rise will be more than 50 centimeters (approximately 20 inches) by century’s end. This could be devastating to coastal cities around the world that are already vulnerable to storms and flooding because of geological or urban planning factors.
That is the finding of a report from Christian Aid looking at eight coastal cities especially vulnerable to the effects of climate change. The Christian Aid report is one of several from organizations around the world being published in anticipation of the Intergovernmental Panel on Climate Change (IPCC) report on how and if the world can achieve the 1.5° Celsius goal, The Guardian reported. The IPCC report, scheduled to be released on Monday, is expected to say that the 1.5° goal is possible with urgent action to reduce greenhouse gas emissions. The Christian Aid report helps illuminate what is at stake.
