The northeast edge of the Venable Ice Shelf, near Antarctica’s Allison Peninsula.
Last summer one of Antarctica's floating ice shelves calved an iceberg the size of Delaware – but scientists say other less dramatic changes reveal more about how and why Antarctica is changing.
Australian forces will need to be prepared for natural disaster relief missions.

Australia faces many security issues driven by climate change, including more international migration and an increase in defence personnel being sent on disaster relief missions, a Senate inquiry has found.
Scientists on Arctic sea ice in the Chukchi Sea, surrounded by melt ponds, July 4, 2010.
Climate change is transforming the Arctic, with impacts on the rest of the planet. A geographer explains why he once doubted that human actions were causing such shifts, and what changed his mind.
The view from Indonesia’s Rote Island towards Australia.
There is plenty of debate over what route was taken by the first people to reach Australia. New research reveals a likely route through a now submerged chain of islands.

Long-term climate modelling may appear to focus on the impossibly far future. But the full impact of some climate processes won't be apparent for centuries.
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.
Mangroves in the Florida Everglades.
As Earth's climate warms, mangroves are expanding north and south from tropical zones. Mangroves reinforce shorelines and store huge quantities of carbon, so protecting them is an effective climate strategy.
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.

Climate change is raising global sea levels. Now research shows that 'hot spots' where seas rise another 4 to 5 inches in five years can occur along the Atlantic and Gulf coasts, further magnifying floods.
If New Zealand introduces a climate refugee visa, 100 Pacific Islanders could be granted access on the basis that their home islands are threatened by rising seas.
New Zealand's plan to create the world’s first humanitarian visa for climate refugees has to consider ways people from Pacific Island nations actually want to be assisted.
Climate fight: a traditional Fijian warrior poses at the UN climate summit in Bonn.
To many people, island nations such as Tuvalu, Kiribati and the Marshall Islands are synonymous with climate catastrophe. But prophesies of doom aren't all that helpful.
Laiap, to the west of the site of the now-disappeared Nahlapenlohd.
In 1850, the Micronesian island of Nahlapenlohd was the scene of Pohnpei state's first battle involving cannons and muskets. Less than two centuries later, it has sunk beneath the waves.
Environmental threats in the Pacific Islands can be cultural as well as physical.

Australia is good at 'hard hat' responses to crises such as cyclones. But a new environmental declaration on the Pacific Islands points out that the best approach is more well-rounded and subtle.
Property is under threat, physically and conceptually, from climate change.
To create property systems that are as dynamic as the landscapes we occupy, we might need to start thinking about ourselves as belonging to and answerable to the land, not the other way around.
The crack along the Larsen C ice has grown significantly over the past few weeks.
A huge iceberg is set to break free from Antarctica. While the iceberg isn't hugely concerning, it could herald the breakup of the entire Larsen C ice shelf, which could trigger more sea-level rise.
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.
Three main excavation squares within Boodie Cave.
Part of the land inhabited by some of the early Australians is now submerged, but details of their life is now revealed in an excavation on an island off the continent’s north-west coast.
Church and climate: two issues that are close to many Pacific Islanders’ hearts.
What does God have to do with climate change? A lot, if you want to engage with communities in the Pacific Islands, where almost everyone goes to church and religious leaders are hugely influential.
Most businesses can ignore the long term effects of climate change. But not football clubs.
The original conflict between development and preservation of natural assets is broadening as the risks of climate change become ever more obvious.
Conflicts over coastal areas have largely been between development and preserving what makes these attractive places to live. Rising sea levels are now complicating our relationship with the coast.
