Study Confirms World's Coastal Cities Unsavable If We Don't Slash Carbon Pollution. A new study confirms what leading climate scientists have warned about for many years now: Only very aggressive climate action can save the world’s coastal cities from inundation by century’s end.

Study Confirms World's Coastal Cities Unsavable If We Don't Slash Carbon Pollution

We still could limit sea level rise to two feet this century if we keep total warming below 2°C, according to analysis using these new findings. Otherwise, we should be anticipating five to six feet of sea level rise by 2100 — which would generate hundreds of millions of refugees. That isn’t even the worst-case scenario.

On the trail of some of the world's rarest monkeys

I had to keep my wits about me as I followed the trail of some of the world’s most endangered primates. My local fixer had wandered off briefly to record the dawn chorus of birds in Vietnam’s Cuc Phuong national park. He returned trembling with fear after a confrontation with two armed hunters carrying bags of animals. This is the reality of conservation work in Vietnam, where 70 per cent of primate species are facing extinction. “Law enforcement is on a very, very low level,” says Tilo Nadler, founder of the Endangered Primate Rescue Center, which is experimenting with releasing them back into the wild and has hosted some dozen PhD researchers so far.

Rising Seas - Interactive: If All The Ice Melted. 4 Enormous Projects That Could Save Coastal Cities In Our Flooded Future. Huge Waves Spotted In The Arctic Ocean. The Arctic Ice-cap has a new enemy: huge waves.

Huge Waves Spotted In The Arctic Ocean

For the first time, 5 meter swells have been detected in the Arctic. The absence of ice provides opportunities for waves to grow, but is also suspected to hasten the break–up of the ice that remains, creating a feedback loop that has not been factored into previous predictions. Although white squalls plague the Great Lakes, waves that are both high and broad are the result of wind blowing over oceanic expanses of water. The distance over which the wind builds the wave is known as the fetch. With the Arctic Ocean is almost entirely surrounded by land, and much of the ocean covered by ice, the length has been restricted. However, the decrease in sea ice (and yes, Daily Mail, it really is decreasing) is making fetch happen, producing waves that can break-up sea ice once they encounter it.

Megacities contend with sinking land. 29 April 2014Last updated at 05:59 ET By Jonathan Amos Science correspondent, BBC News, Vienna Inundation of flood water in these cities is becoming a more significant problem Subsiding land is a bigger immediate problem for the world's coastal cities than sea level rise, say scientists.

Megacities contend with sinking land

In some parts of the globe, the ground is going down 10 times faster than the water is rising, with the causes very often being driven by human activity. Decades of ground water extraction saw Tokyo descend two metres before the practice was stopped. Speaking at the European Geosciences Union General Assembly, researchers said other cities must follow suit. Gilles Erkens from the Deltares Research Institute, in Utrecht, in the Netherlands, said parts of Jakarta, Ho Chi Minh City, Bangkok and numerous other coastal urban settlements would sink below sea level unless action was taken.

PPP in combating climate change

Interventions will be required over a long time for adaptation and mitigation. They will need to adopt different approaches to programming, while the ongoing development initiatives will need to be sensitive to climate change. One such approach is Public Private Partnership (PPP). People in semi-urban and rural areas directly depend on climate-sensitive sectors like agriculture and businesses for their livelihoods. Many, if not most, of the large scale “solutions” will continue to be undertaken by the government.

Due to the global scale of the challenge, we need multiple actors including private sector funding and diverse sources of expertise to deliver sustainable solutions. British Isles in 2100 by JaySimons on deviantART. This 10-Mile Loop Of Parks Would Protect New York From Rising Water. As sea levels rise along the New York City waterfront, “100-year” storm surges may eventually happen as often as every three years, with more chances of Sandy-like damage if the city doesn’t rebuild its borders.

This 10-Mile Loop Of Parks Would Protect New York From Rising Water

One redesign under consideration now: Big U, a 10-mile long shield of parks and community spaces that would help protect Manhattan neighborhoods from flooding. Designed by Bjarke Ingels Group (BIG) and a network of collaborators over the last 10 months, Big U is one of 10 finalists in the Rebuild by Design competition launched by the U.S. Department of Housing and Urban Development last year. The design is focused as much on the everyday needs of local neighborhoods as on flood protection--an approach that's very different than how infrastructure has been built in the past.

In New Orleans after Katrina, floodwalls were made to meet engineering criteria, not social needs. “Because they all work individually, you end up with a system that’s resilient.
