One million species at risk of extinction, UN report warns

The bonds that hold nature together may be at risk of unraveling from deforestation, overfishing, development, and other human activities, a landmark United Nations report warns. Thanks to human pressures, one million species may be pushed to extinction in the next few years, with serious consequences for human beings as well as the rest of life on Earth.

5 Top Italian Art Cities Where You Can Also Go To The Beach

While you probably don’t head to Italy’s major art cities to go to the beach, with many of them you can. Here are coastal areas close to some of Italy’s top culture stops that are good for a seaside break after a morning of museum hopping when temperatures soar.

What’s the future for Sri Lanka’s ‘lost’ population of whales?

Flocking tourists are making it less of a safe place for these stunning animals.

Seagrass’ strong potential for curbing erosion

A new study shows how seagrass can help to protect shorelines against erosion and help to mitigate damage from rising sea level, potentially providing useful guidance for seagrass restoration efforts.

Tapping fresh water under the ocean has consequences

Coastal communities may consider using offshore groundwater resources as populations increase and the limited freshwater resources are degraded by overuse and pollution, but new research suggests tapping into them could lead to adverse impacts onshore.

Strong winds are supersizing the ocean’s biggest waves

Strong winds are driving the ocean’s biggest waves to dizzying new heights. The University of Melbourne researchers behind the work, published April 25 in the journal Science, say the supersized waves could compound the effects of rising sea levels, leading to more frequent flooding and accelerated coastal erosion.

Indonesia plans to relocate its capital from Jakarta

Indonesia plans to move its capital city from Jakarta, according to the country’s planning minister. Jakarta is home to more than 10 million people according to the United Nations, with an estimated 30 million in the greater metropolitan area. The nation is prone to flooding and is sinking at an alarming rate.

El Niño and our beaches; By Gary Griggs

Erosion, Inform

Our beaches come and go seasonally in response to changing wave conditions. The larger and more energetic winter waves stir up the beach sand and carry it offshore, eroding the shoreline back. Six months or so later, the smaller and less energetic spring and summer waves gradually move that sand back onshore, building the beach just in time for all the summer visitors.

Antarctica’s Effect on Sea Level Rise in Coming Centuries

There are two primary causes of global mean sea level rise — added water from melting ice sheets and glaciers, and the expansion of sea water as it warms. The melting of Antarctica’s ice sheet is currently responsible for 20-25% of global sea level rise.

Preventing collapse after catastrophe

As the impacts of climate change escalate, ecosystems will likely undergo events that will disrupt entire populations. In marine ecosystems, anthropogenic warming has subjected organisms to elevated temperatures, oxygen loss, and acidification. The increased frequency and severity of catastrophic events may inhibit a population’s ability to recover and, in turn, may spur collapse.
