Sea levels are rising. Time to build …. floating cities?

WITH SEA LEVELS expected to rise at least 26 inches by the end of the century, due to human-driven climate change, to say that we have a problem is an understatement. By the middle of the next century, many of the world’s major cities will be flooded, and in some cases, entire island nations will be underwater. The people who live there will have to relocate. But to where?

With sea levels rising, is it time to contemplate floating cities?

On Wednesday, the United Nations Human Settlements Program, or UN Habitat, convened its first roundtable to discuss the possibility of floating cities as a solution to this problem. Held at its headquarters in New York City, on the banks of the East River, the location was fitting given that the room itself might be underwater within a century. The specific proposal that dozens of scientists, engineers, artists, and investors came to discuss was Oceanix City, which aspires to create a scalable platform for the seafaring civilizations of tomorrow.

Sydney to ditch cars by 2056: report.

Planners envisage that by the middle of this century most Sydneysiders will be able to reach their place of work within 30 minutes using public transport or ‘‘active’’ options, such as walking or riding.

Sights such as this will be substantually lessened by
mid-this century if Sydney's plans come to fruition.

The NSW Government has released its Future Transport Strategy 2056 report, which suggests investment will increasingly be focused on ‘‘three cities’’ built around Western Sydney Airport, Greater Parramatta and the existing CBD.

‘‘Customers will be able to travel to one of these cities or to their nearest centre within 30 minutes of where they live by public or active transport,’’ the report states.

‘‘This will give people better access to access jobs, eduction and essential services.’’

The report suggests getting people out of their cars and using sustainable transport will reduce congestion and emissions and improve air quality and wellbeing.

‘‘Well-planned centres and cities will enable a shift from private cars to public transport and active transport modes, such as walking and cycling,’’ the strategy says.

‘‘In Sydney, the key to this will be the delivery of three 30-minute cities, supported by reliable ‘turn up and go’ mass transit services.’’

Active transport for short trips will be encouraged by providing safe and accessible footpaths with seating and shade.

There’ll also be better pedestrian crossings, lower traffic speeds, separated cycling paths and secure bicycle storage.

The report notes that by 2056 NSW will have more than 12 million residents.

Sydney will be a global city similar in size to London or New York.

Premier Gladys Berejiklian released the transport strategy yesterday alongside the State Infrastructure Strategy and the Greater Sydney Region Plan.

‘‘Now for the first time we have a co-ordinated vision for our state for the next 10, 20, 30 and 40 years,’’ Ms Berejiklian said.

‘‘It’s a plan that makes sure communities can expect to have jobs in their local area, shorter travel times and a better environment, which ensures lots of open and green spaces.’’

Transport Minister Andrew Constance said: ‘‘We want to improve public transport and roads so, that by 2056, 70 per cent of people live within 30 minutes of where they work or study.’’

Ireland Demonstrates Climate Leadership with €22 billion Investment Plan

The Government of Ireland has announced it will invest €22 billion to transition the country to a low carbon and climate resilient society, aiming at almost zero emissions by middle of the century.

Ireland demonstrates leadership with regard climate change.

According to the country’s National Development Plan published this month, the funds are to be primarily deployed to reduce carbon emissions from transport, agriculture and the energy sector, along with flood defenses.

“While Ireland clearly faces a very significant task in reducing its greenhouse gas emissions, the current profile of which reflects the particular structure of our economy, action can be taken now to position Ireland to harness significant benefits from realising a low-carbon economy,” the report says.

Braidwood farmers struggle with drought as dams dry up

Farmers in the New South Wales Southern Tablelands are in the middle of one of the driest summers in recent memory, and are facing tough choices about how to deal with bone-dry dams.

Six dams on Mark Horan's property have dried up.

Water has been scarce on Mark Horan's Braidwood farm since winter, and a recent spate of hot weather has left him running on empty.

Most of the dams on Mr Horan's property are dry, and grass for cattle feed is increasingly sparse.

We don’t need to save endangered species. Extinction is part of evolution

Near midnight, during an expedition to southwestern Ecuador in December 2013, I spotted a small green frog asleep on a leaf, near a stream by the side of the road. It was Atelopus balios , the Rio Pescado stubfoot toad. Although a lone male had been spotted in 2011, no populations had been found since 1995, and it was thought to be extinct. But here it was, raised from the dead like Lazarus. My colleagues and I found several more that night, males and females, and shipped them to an amphibian ark in Quito, where they are now breeding safely in captivity. But they will go extinct one day, and the world will be none the poorer for it. Eventually, they will be replaced by a dozen or a hundred new species that evolve later.

Mass extinctions periodically wipe out up to 95 percent of all species in one fell swoop; these come every 50 million to 100 million years, and scientists agree that we are now in the middle of the sixth such extinction, this one caused primarily by humans and our effects on animal habitats. It is an “immense and hidden” tragedy to see creatures pushed out of existence by humans, lamented the Harvard entomologist E.O. Wilson, who coined the term “biodiversity” in 1985. A joint paper by several prominent researchers published by the National Academy of Sciences called it a “biological annihilation.” Pope Francis imbues the biodiversity crisis with a moral imperative (“Each creature has its own purpose,” he said in 2015), and biologists often cite an ecological one (we must avert “a dramatic decay of biodiversity and the subsequent loss of ecosystem services,” several wrote in a paper for Science Advances). “What is Conservation Biology?,” a foundational text for the field, written by Michael Soulé of the University of California at Santa Cruz, says, “Diversity of organisms is good . . . the untimely extinction of populations and species is bad . . . [and] biotic diversity has intrinsic value.” In her book “The Sixth Extinction ,” journalist Elizabeth Kolbert captures the panic all this has induced: “Such is the pain the loss of a single species causes that we’re willing to perform ultrasounds on rhinos and handjobs on crows.”
