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.
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?
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.
The site of the hillfort of Vugala, northern Viti Levu island (Fiji). This was one of many hillforts in the area – home to a few hundred people according to reports from the 1840s – that were probably established around AD 1400 in response to conflict resulting from a food crisis that had come about as a result of an enduring fall in sea level.
Rising seas are one of the major concerns of Pacific Island nations, and looking at past sea-level change can help understand the future.
Where the ice meets the sea: Antarctica’s ice shelves play a key role in how fast ice sheets melt.

As the world warms, Antarctica's melting ice will likely reach the point of no return.
Clearing mulga woodland in Queensland to open up land for cattle during drought.
We're going to have to adapt to climate change, but some of the options on the table could do more harm than good if they destroy the ecosystems that protect us.
In the aftermath of 2012’s deadly Hurricane Sandy, New York launched a US$20 billion plan to defend the city against future storms as well as rising sea levels.
Managing the impacts of rising seas for some communities is being made more difficult by the actions of governments, homeowners – and even some well-intentioned climate adaptation experts.
The low-lying islands of the Pacific such as Kiribati are vulnerable to sea level rise.

Australia need to take responsibility for the consequences of its fossil fuel consumption and exports.
Gamba Grass is altering fire regimes in the Top End, threatening human life and property, natural assets including Kakadu and Litchfield National Parks, and compromising savanna burning programs.
One of the Australian government's new research priorities is "environmental change". But can be hard to know how to tackle such huge and interlinked issues as climate change and species extinctions.
OK, but which sea’s level? And how do you know what it is?
The tides come in, the tides come out. But what is a sea's level? Technology has evolved since we first started gauging the height of the ocean in comparison to the land.
Whale sharks were one of the warm water species to move south during the 2010-2011 marine heatwave.
While eastern Australia trembles in the face of an El Niño, Western Australia's oceans could finally see relief from devastating marine heatwaves.
It may already be too late to stop Antarctic ice sliding into the ocean.
Ice sheets respond slowly to changes in climate, because they are so massive that they themselves dominate the climate conditions over and around them. But once they start flowing faster towards the shore…
