Recent studies reveal alarming projections regarding the effects of climate change on polar ice sheets and sea levels. Even if global warming is limited to 1.5°C, significant sea level rise is likely, necessitating urgent action to mitigate its impacts. Research indicates that the 1.5°C target may be too high to preserve polar ice sheets, with irreversible consequences for coastlines and glaciers. Furthermore, scientists highlight that glaciers may take centuries to recover, even if global temperatures are reversed. The findings underscore the critical need for stricter climate targets and immediate intervention to protect vulnerable ecosystems.
