A new study has reported the world will lose almost half of its valuable sandy beaches by 2100 as sea levels rise. But cutting our emissions could keep some intact.
The research vessel must dodge dangerous icebergs as it drills for sediment core samples.
A paleooceanographer describes her ninth sea expedition, this time retrieving cylindrical 'cores' of the sediment and rock that's as much as two miles down at the ocean floor.

Cyclone Idai hit poor countries the hardest and shows why disaster resilience is a necessity.
Klipbokberg, Grootrivierhoogte, in the Cederberg. These mountains contain clues about ancient landscapes.
A record of sea-level change from 400 million years ago in South Africa, reveals how ecosystems and environments collapsed at the South Pole.

For many world heritage sites, flood risks are increasing. But what about places that don't have the funds for protection?

While extreme weather conditions represent a considerable challenge globally, some communities have been living with (and adapting to) similar events for centuries.
Climate change could affect South Africa’s tourism.
Research says South Africa's picture perfect weather conditions are a tourist's dream.
The process of laying internet cables on the sea floor is particularly sensitive at the coastlines.
Comparing the locations of key internet data centers and cable routes with maps of expected sea-level rise suggests it's time to shore up internet connections in the face of a changing climate.
King tides now regularly breach seawalls meant to protect Torres Strait Island communities, and it happened again last week.
King tides and rising seas are an increasing and predictable threat, but adaptation plans to limit the damage to coastal property are still not managing the political obstacles.
Australia’s coastline has moved before thanks to changes in sea level.

People have been forced to move in the past thanks to changes in sea levels that affected Australia's coastline.
Warm waters run very deep.
Water mass enters the ocean from glaciers such as this along the Greenland coast.
Greenland's ice is largely responsible for the accelerating pace of sea-level rise. A new analysis shows that, while Greenland accounted for just 5% of the rise in 1993, that figure rose to 25% by 2014.
A big part of South Africa’s appeal lies in its good weather. Climate change poses a risk to the tourism industry.

South Africa's weather is very attractive to international visitors. Climate change could alter their perceptions unless mitigation strategies are put in place.
In New York the sea will rise by up to two metres.

At 2°C of warming and beyond, many megacities will have to cope with increased flood-risk.

Australia's coastal towns are already facing storms and erosion – problems that are set to get worse with rising seas.
How does Peter Singer’s figure of 750 million fit within the range of estimates on ‘climate change refugees’?
Ethicist Peter Singer told Q&A that climate change-related sea level rises are "estimated to cause something like 750 million refugees just moving away from that flooding". Is that accurate?

Wild seas have left beaches eroded and houses close to collapse.
Climate change isn't the only thing making sea levels higher and cyclones more intense.
The Solomon Islands are low-lying and vulnerable to changes in sea level.
Sea levels are rising faster in the Solomon Islands – and send a warning for the rest of the world.
Glaciers have been a major contributor to sea-level rise.
Could sea levels really rise by several metres this century. Probably not, although this century's greenhouse emissions could potentially set the stage for large rises in centuries to come.
