Rising Seas Threaten Coastal Ecosystems
17,000 years
ago, lower sea levels allowed
walking from Russia to America and Australia to Tasmania.
Today, human-caused
global warming
is causing
sea levels to rise
over a
meter per century.
New study in Nature examines
how coastal ecosystems adapted
during the
last Ice Age.
Mangroves, marshes, and coral reefs
vital for
coastal protection and biodiversity.
Research suggests coastal habitats can adapt to some sea level rise, but there's a
tipping point.
Mangroves found in tropical regions may struggle to survive
global warming-induced flooding.
Coastal marshes in
North America and Europe
play a key role in
erosion prevention.
Australia has
one million hectares of coastal marshes
facing the
threat of waterlogging.
Coral reefs protect islands, but they'll vanish underwater
beyond 2°C global warming.
With sea levels rising, preserving coastal habitats becomes
critical for a sustainable future.
