Little Missouri River, North Dakota.
Recent research shows that US rivers are becoming saltier and more alkaline. Salt pollution threatens drinking water supplies and freshwater ecosystems, but there is no broad system for regulating it.
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.
Coastal municipalities need to prepare for higher chances of storms and rising sea levels.

People have been forced to move in the past thanks to changes in sea levels that affected Australia's coastline.
Dooagh beach, Ireland.
A entire beach in Ireland has returned 33 years after being washed away.
Early in the morning and late in the evening is when shorebirds escape disturbance on the beaches on which their survival depends.
We aren’t just jostling with each other for beach space. Scuttling, waddling, hopping or flying away from beachgoers all around Australia, wildlife struggles to survive the daily disturbances.
Mangroves have died along a 1,000km stretch of coastline in the Gulf of Carpentaria.
In early 2016 reports appeared that vast swathes of mangroves had died in the Gulf of Carpentaria. It now appears heat and drought were to blame.

Many Australians live on the coast, but how much do we know about the risks? While average sea levels are relatively easy to gauge, the risk of flooding also depends on weather, landscape, and climate.

Australia's coastal towns are already facing storms and erosion – problems that are set to get worse with rising seas.
Bathers on Perranporth beach in Cornwall stay in the safe area marked by lifeguards, with large rip currents visible to either side.
Knowing how rip currents form and how to spot them could save your life.

Blue bottles have been washing up on beaches lately, but what exactly are they? And are you really supposed to pee on their stings?
Mangroves put their roots down where few other plants will.
Mangroves - one of the most important trees - are threatened by rising seas. While these forests can adapt, human development is getting in the way.
Every year millions of birds migrate between Australia and the northern Hemisphere.
Five million shorebirds migrate between Australia and the northern hemisphere, threatened by habitat destruction, and rising seas. How can we protect this natural marvel?
Hefty problem: a local council was left with a huge clean-up bill after a dead whale washed up in Perth last year.

Dead whales can cost beachside ratepayers a lot to clean up. The alternative is to tow them away before they wash up - but the legal question of who does the job is far more complex than it sounds.
Apollo Bay in Victoria. Australia’s coastal towns are vulnerable to changes in the surrounding seas.
Australia’s coastal towns, many built around fisheries and tourism, are particularly vulnerable to climate change. South east and south west Australia are marine hotspots — they are warming much faster…

Human activity is driving sea levels higher. Australia’s seas are likely to rise by around 70 centimetres by 2100 if nothing is done to combat climate change. But 2100 can seem a long way off. At the moment…
Swings and roundabouts: sea level rises are hard to predict.
Coastal and river flooding struck Britain again this week with huge waves hitting southern and western coasts and around 100 flood warnings still in place by Wednesday evening. Disturbing but, sadly, not…
Double jet lag? No thanks.

You get hauled out of bed in the morning not just because of an alarm clock. We are genetically encoded with a 24-hour (circadian…
Coastal Australia: many different activities, many different kinds of coasts.

Most of Australia’s population and infrastructure are on the coast. Continuing development pressure, global environmental threats and climate change are increasing the risk to the integrity of the coast…
