Mangroves grow in saltwater along tropical coastlines, but scientists have found them along a river in Mexico’s Yucatan, more than 100 miles from the sea. Climate change explains their shift.
A new modelling approach improves projections of Antarctica’s future ice loss. It shows a low-emissions scenario would avoid the collapse of West Antarctica’s ice sheet and limit sea-level rise.

How scientists are improving their understanding of the connection between extremes and climate change – and what’s to come. Listen to The Conversation Weekly.
If the world is to adapt to sea level rise with minimal cost, we must address the uncertainty surrounding Antarctica’s melting ice sheet. This requires significant investment in scientific capacity.
As the state copes with hurricanes and climate disasters, it is figuring out how to manage the slow-motion loss of its coastal land. But its plans could endanger the cultures that define the region.
A new analysis, using 15 years of autonomous underwater measurements and simulations from the latest global climate models, refined our estimate of future ocean warming and sea level rise.
From Fiji to France to Central Australia, stories abound of lands lost beneath the sea. Some are likely founded on millennia-old memories of coastal submergence, offering us clues today.
What might sound like small changes – temperatures another tenth of a degree warmer, sea level a few centimeters higher – have big consequences for the world around us.
The IPCC report has laid out some alarming sea level projections for the future. But the relationship between sea level rise and real-world risk is complex.
Some of the climate changes will be irreversible for millennia. But some can be slowed and even stopped if countries quickly reduce their greenhouse gas emissions, including from burning fossil fuels.
The Army Corps of Engineers is planning a sea wall 6 miles long and flood gates. The infrastructure might protect downtown from a hurricane storm surge, but most of the area will still be vulnerable.

The triple whammy of the moon’s wobble, sea level rise and more intense storms will bring worse tidal floods into coastal communities in the 2030s. This includes in Australia.
In principle, some portion of the shoreline is public land along virtually all US coasts. But these can sometimes overlap with private property interests, creating confusion and conflict.
