Water World: Sea Level Rise in Real Life

Sea levels have risen along the East Coast around 6 to 8 inches since 1960. Under different global warming scenarios, seas could rise 8 inches to several feet by 2100.

The longer term concern is that if warming causes the collapse of the Greenland and/or Antarctic ice sheets, seas could rise tens of feet, although it is thought a rise of that magnitude would take hundreds of years.

Nickolay Lamm, a 24-year-old researcher and artist from StorageFront.com, was motivated to gain a better idea of what such a devastating rise in sea level would look like. And so he created a set of surreal images showing treasured landmarks swallowed by sea water.

To create these visualizations, Lamm took stock photos of the different landmarks, used Google Earth to determine their exact location, and applied mapped sea level rise projections obtained from Climate Central.

In addition to the Jefferson and Washington monuments, he created visualizations from landmarks in Miami, New York City, and Boston viewable in a multimedia post at Mashable.com

“The inspiration for these sea level rise photos came from What Could Disappear from the New York Times,” Lamm wrote on his blog. “Because the maps shown were not in a high enough resolution to figure out exactly which places would be flooded, I got in touch with Remik Ziemlinski from Climate Central who gave me access to more precise versions of the same maps that New York Times used.”

Even if you’re skeptical of some of the more alarming and dramatic sea level rise projections from global warming, these visuals can give you a realistic sense of what hurricane storm surge flooding could do in these East Coast cities. Major hurricanes could bring double digit foot surges up and down the East Coast (although a 25-foot surge is probably unrealistic – in the current climate).

Hurricane Sandy swamped sections of New York City with a 14 foot surge, and, in 2003, Hurricane Isabel sent an 8-foot surge up the Potomac River.

Climate Change Is Taking Place 'Before Our Eyes'

 

When in September the Arctic sea ice that freezes and melts each year shrank to its lowest extent ever recorded and then contracted a further 500,000 sq km, the small world of ice scientists was shocked.

This was unprecedented, yet there was nothing unusual about the meteorological conditions in the Arctic in 2012, no vast storms to break up the ice, or heatwave to hasten the retreat.

Only widespread warming of the atmosphere could have been responsible for less ice growth during the winter and more ice melt during the summer, the scientists concluded.

It was, said the World Meteorological Organisation (WMO), just one of dozens of major physical events in 2012 that convinced many people that the extremes have become normal.

The most dramatic event was possibly hurricane Sandy, which swept through the Caribbean and up the east coast of the United States, leaving hundreds dead and thousands without power or shelter.

But just a few weeks later it was possibly surpassed in strength by super-typhoon Bopha, which roared across Mindanao in the Philippines killing at least 900 people and leaving hundreds of thousands of people displaced.

Typhoons aren’t unusual in the Philippines or the US, but both of these were well outside their normal timescale and location.

Officially, said the WMO, the first 10 months of 2012 were the ninth-warmest since records began in the mid-19th century, with early months cooled by a La Niña weather event in the Pacific. In addition, 2012 broke the record for carbon dioxide concentration in the atmosphere.

Governments saw records tumble almost every season. According to Nasa, it’s now been 28 years since the globe experienced temperatures cooler than the 1951-1980 average. Globally, 10 of the 11 hottest years have now been in the last 11 years.

The US was on course to experience by far its hottest year on record. Nearly 15,000 new daily heat records were set and Europe had its warmest spring ever recorded.

Heatwaves, droughts, floods and hurricanes battered vulnerable countries. “The danger signs are all around. One-third of the world’s population lives in countries with moderate to high water stress; land degradation affects 1.5 billion people. Ice caps are showing unprecedented melting, permafrost is thawing, sea levels are rising. The abnormal is now the new normal,” said UN secretary general Ban Ki-moon.

Former US vice-president Al Gore backed this up: “Every night on the news now, practically, is like a nature hike through the Book of Revelation.”

“Far-reaching changes [are] taking place on Earth’s oceans and biosphere. Climate change is taking place before our eyes and will continue to do so as a result of the concentrations of greenhouse gases in the atmosphere, which have risen constantly and again reached new records,” said Michel Jarraud, head of the Geneva-based WMO.

Adapting to a warmer world: No going back

When Superstorm Sandy hit the US coast last month, it blew millions of New Yorkers back into the nineteenth century.

The southern part of Manhattan went black after floodwaters shorted out electrical systems. With the subway system disabled, many residents resorted to traversing the island by foot, and water supplies in some areas became contaminated with bacteria and pollutants.

The largest Atlantic hurricane on record, Sandy wreaked US$50 billion in economic losses along the US northeast coast, providing a costly reminder of how ill-prepared even the richest nations are for weather extremes. Some recent weather disasters have now been attributed, at least in part, to human activity, including the 2003 European heatwave1 and the floods in England in 2000 (ref. 2). According to the Intergovernmental Panel on Climate Change (IPCC), storms, floods and droughts will strike more frequently and with greater strength as the climate warms3. And if nations are struggling to cope now, how will they manage in a warmer, harsher future?

Just a decade ago, 'adaptation' was something of a dirty word in the climate arena — an insinuation that nations could continue with business as usual and deal with the mess later. But greenhouse-gas emissions are increasing at an unprecedented rate and countries have failed to negotiate a successor to the Kyoto Protocol climate treaty. That stark reality has forced climate researchers and policy-makers to explore ways to weather some of the inevitable changes.Nature special:nature.com/kyoto

“As progress to reduce emissions has slowed in most countries, there has been a turn towards adaptation,” says Jon Barnett, a political geographer at the University of Melbourne in Australia.

Adaptation has tended to focus on hard defences, such as shoring up sea walls and building dams. But as awareness of adaptation has grown, so too has the concept. “Adaptation means different things to different people, and is extremely location specific,” says Neil Adger, an environmental and economic geographer at the University of Exeter, UK. Although residents in Bangladesh can raise their houses on stilts to survive floods, some settlements in Alaska and the Maldives must move in the face of rising sea levels. More

Island Nations Criticize EU Over Kyoto Climate Deal Extension

A bloc of 42 island nations said the European Union is backtracking on agreements made at the last round of United Nations climate talks in Durban, South Africa, threatening the environmental integrity of an eventual treaty.

The 27-nation EU joined with the Alliance of Small Island States and other developing nations in Durban to push for a road map leading to a new climate treaty drawing in all nations. Now the Europeans are pulling back from some commitments, according to a statement e-mailed today by the island bloc.

The EU in Durban agreed to accept new emissions targets after 2012, while working to increase the global ambition of greenhouse gas cuts. EU environment ministers on March 12 opted for an eight-year second commitment period of the Kyoto Protocol that ends in 2020, three years longer than the island nations want. At the same time, the low-lying nations are seeking deeper emissions cuts to contain temperature gains and sea-level rises.

“Regrettably, our shared concerns seemed to have diverged when our planes left South Africa,” Marlene Moses, chairwoman of the alliance and Nauru’s ambassador to the United Nations, said in the statement. “The EU is resisting elements key to the environmental integrity of the climate treaty,” she said, citing the length of Kyoto’s second commitment period and a failure to accept more ambitious mitigation targets.

Mortal Combat: Tuvalu versus China

Low-lying island nations demand dramatic action on climate change. The big boys shrug.

Low-lying island nations demand dramatic action on climate change. The big boys shrug. If I were to guess which group of people currently living on the planet cared least about the ClimateGate hacked e-mail controversy, I'd bet on the citizens of the Alliance of Small Island States.
Members of the Alliance --- a group of about 45 islands and other low-lying nations -- take rising sea levels a bit more seriously than your average think tank funded by Exxon. Their very existence is threatened, and they are making a stink about it at the climate change talks in Copenhagen.
A study published this week in the Proceedings of the National Academy of Sciences contends that global sea levels may rise almost two meters by the end of this century, faster than predicted by the International Panel on Climate Change.
