Natalya Gomez<p>🌊 We’re proud to share our new study in npj Urban Sustainability, which makes a first-order estimate of how many buildings across the Global South are exposed to sea-level rise. Using Google’s Open Buildings data and a high-quality elevation model, we find ~3 million buildings at risk with 0.5 m of rise—a level already locked in even under rapid emissions cuts—and >100 million if emissions continue.</p><p>These findings reveal the vast scale of buildings that could be saved with swift fossil fuel cuts—and show the urgent need to prepare for the changes already underway.</p><p>Press release: <a href="https://www.mcgill.ca/newsroom/channels/news/millions-buildings-risk-sea-level-rise-mcgill-led-study-finds-368163" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">mcgill.ca/newsroom/channels/ne</span><span class="invisible">ws/millions-buildings-risk-sea-level-rise-mcgill-led-study-finds-368163</span></a></p><p>Paper: <a href="https://www.nature.com/articles/s42949-025-00259-z" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">nature.com/articles/s42949-025</span><span class="invisible">-00259-z</span></a></p><p><a href="https://fediscience.org/tags/ClimateChange" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ClimateChange</span></a> <a href="https://fediscience.org/tags/SeaLevelRise" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SeaLevelRise</span></a> <a href="https://fediscience.org/tags/ClimateAction" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ClimateAction</span></a> <a href="https://fediscience.org/tags/ClimateScience" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ClimateScience</span></a> <a href="https://fediscience.org/tags/UrbanSustainability" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>UrbanSustainability</span></a> <a href="https://fediscience.org/tags/CoastalCommunities" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CoastalCommunities</span></a></p>
