Over 70% of coral reefs in the tropical western Atlantic Ocean are projected to be in a state of erosion by 2040, increasing to nearly all reefs in 2100 if warming exceeds 2 °C above preindustrial levels, a study in Nature suggests. go.nature.com/48m9Y8F 🌊 🧪

Our paper out today in @nature.com describes a grim fate for coral reef growth under climate change in the Western Atlantic. We also estimate that reef restoration could offer pockets of local hope, but overall cannot keep up with the effects of climate change www.nature.com/articles/s41...
Reduced Atlantic reef growth past 2 °C warming amplifies sea-level impacts - Nature
An analysis of coral reefs in the tropical western Atlantic suggests that nearly all will be eroding by 2100 if global warming exceeds 2 °C, which will worsen the effects of sea-level rise.

Thanks for arranging this #ITRS2025 workshop 🤩 It was a very useful exercise, and I loved going through all the steps of planning our perfect will-never-ever-get-funded project 😂 and to make our priorities when reality (i.e. huge funding cuts) were thrown at us 😂

Can tropical corals find refuge at higher latitudes under future warming? In our new paper in Science Advances, we argue that coral range expansion will be *far too slow* for most coral species to outpace climate change. 🪸🌊

Anthropogenic climate change will likely outpace coral range expansion
Coral reef range expansion takes centuries, and higher-latitude seas are therefore ineffective refugia for most tropical corals.

Check out @ashtyn-isaak.bsky.social and her experiment at @seasim-aims.bsky.social along with other PhD student @hollykoch20.bsky.social ! Such an exciting collaboration and experiment! It explores how light and temperature related bleaching differs from the effects of ocean acidification
PhD candidates @ashtyn-isaak.bsky.social & @hollykoch20.bsky.social are researching how ocean acidification and high light contribute to bleaching, which includes:
🧪36 tanks, 4 species, 12 treatments, 400+ samples
🧬2 corals & 2 crustose coralline algae
🔬 Drivers: light, temp, & 4 levels of PCO2
