Seeding the Ocean: Inside a Michelin-Starred Chef's Revolutionary Quest to Harvest Rice From the Sea

  Seeding the Ocean: Inside a Michelin-Starred Chef's Revolutionary Quest to Harvest Rice From the Sea Seeding the Ocean: Inside a Michelin-Starred Chef's Revolutionary Quest to Harvest Rice From the SeaIt is these creations, and the relentless curiosity behind them, that have helped turn León into one of most influential chefs in the world. The Spaniards call him the Chef del Mar, a man singularly dedicated to the sea and its bounty. But Aponiente isn’t anything like other gilded seafood temples around the world. You won’t find Norwegian lobster there. Or Scottish langoustines. Or Hokkaido uni. In fact, unless you’re an Andalusian fisherman it’s unlikely you’ll know most of the species León serves to his guests.

Coastal communities are experiencing sea level rise four times worse than global water rise, according to a new study released Monday.

Groundwater pumping, extraction of materials from the ground and sediment production are all happening near the coasts and that is causing the land to actually sink -- compounding the effects of a rising sea level.

Trade candidate: Jon Gray

  Trade candidate: Jon Gray Much has been written about the Rockies potentially trading stars Nolan Arenado and Trevor Story. There has been decidedly less chatter about starter Jon Gray. On the surface, though, the right-hander looks to be one of the more sensible trade candidates around the league. © Kevin Jairaj-USA TODAY Sports That’s mostly a function of his contractual status. Gray has five years and sixty-two days of MLB service, meaning he’ll hit free agency at the end of next season. Meanwhile, contending in the NL West will be an uphill battle for the Rockies.

It is no coincidence that these are the same locations where people live, worsening the impacts and increasing the vulnerability.

Many of the largest, most populated cities in the world are built along the deltas of major rivers, where there is the added exposure of rivers connecting to the ocean.

Much of the coast is uninhabited by people, but where there is civilization, there tends to be a greater rise in water levels.

According to the study, it quantifies "global-mean relative sea-level rise to be 2.5 mm per year over the past two decades. However, as coastal inhabitants are preferentially located in subsiding locations, they experience an average relative sea-level rise up to four times faster at 7.8 to 9.9 mm per year."

Coastal lands are sinking

This is the first ever study that factors in land subsidence into current sea level rise observations globally.

"We've actually quantified (sea level rise) and are able to get the relative magnitude. And it's surprising -- it's surprisingly large. We're making the point that climate change is bad and climate induced sea level rise is bad," Robert Nicholls, lead author of this research and director of the UK's Tyndall Centre for Climate Change Research, told CNN.

"But we have this additional process that is making things even worse. And of course, these things add up. It doesn't really matter whether the sea rises or the land sinks, the people living on the coast still have the same impacts."

Sea level rise is happening in many parts of the world. Where the land is rising, sea level rise is not as significant. Not as many people live where the land is rising, however.

But where the land sinks, the relative rise of the sea is higher -- and unfortunately that is where people tend to live. In fact, more than one in five people live along the coastline where the sea level is increasing at 10 mm (or 0.4 inches) or more per year, despite the fact that it encompasses less than 1% of the world's coastline.

map: This global map shows the average relative sea level rise rate in millimeters per year, and is weighted for population (second map). The map is divided into 23 different coastal regions, and the shadings are based on how sea levels are currently rising every year. When weighting the data to population opposed to coastal length (first map), the sea level rise is greater because of human activity that promotes subsidence and loss of elevation. Portions of Asia are experiencing the highest rate of water rise when factoring in both the length average and population average.

In other parts of the world, like parts of the southeastern US, geological changes are not big contributors.

"There's places where the land isn't really moving much at all," said Brian McNoldy, a senior research associate at the University of Miami who was not a part of the study. "And you really are just seeing the effects of ocean levels increasing."

One of the biggest contributors to this subsidence is river deltas.

Either way, these rookies will make impacts at some point. Get to know MLB's next wave of stars and add them to your 2021 fantasy baseball cheat sheets and dynasty/keeper rankings.Last season, Seattle's Kyle Lewis and Chicago's Luis Robert, who finished 1-2 in the AL Rookie of the Year voting, each clubbed 11 home runs, a rate that would have translated to 30 dingers over a full 162-game season. Lewis also swiped nine bags to lead all rookies. Alec Bohm solidified himself as the Phillies’ third baseman of the future by posting a .338 average and a .400 on-base percentage over 44 games.

"Deltas are where rivers bring sediment to the sea," Nicholls said. "And the weight of the sediment plus the compression with the sediment causes consolidation ... So you don't get (rising land) with the deltas, you just get sinking and that can be exacerbated by groundwater withdrawal and drainage."

"Rapid rates of subsidence in deltas and especially cities on deltas are also human-caused, mostly due to groundwater pumping, also oil and gas extraction, and sediment resupply prevented by upstream dams, flood defenses, sand extraction or mining."

Scientists have already been aware of the implications of human-linked climate change to sea level rise, but now there is research that investigates rising and lowering land also caused by humans.

"The process that we're really talking about here is fundamentally down to where people choose to live. And then the fact that they actually made the subsidence worse."

There is a natural cause of the rising and sinking lands, however. According to the study, the melting ice sheets during the ice age thousands of years ago lead to and is still causing rising land near Hudson Bay in Canada.

Asia experiencing highest rate of sea level rise

Coastal sections of Asia have been the most impacted by sea level rise in relation to land subsidence. That's because there is a prevalence of deltas and very populous cities.

Low-income and Latino neighborhoods endure more extreme heat in the Southwest, study shows

  Low-income and Latino neighborhoods endure more extreme heat in the Southwest, study shows In the Southwest U.S., where heat can be deadly, research shows low-income and predominantly Latino neighborhoods endure hotter temperatures.In leafy neighborhoods with trees and shade, the air stays cooler and more bearable. But in exposed areas where the sun beats down on pavement and concrete, the heat soars.

"South, Southeast and East Asia is noteworthy, as these regions collectively contain 71% of the global coastal population below 10 m in elevation," according to the research.

"In Jakarta, subsidences of over 10 centimeters per year -- It may be even locally faster than that. You can get very, very large changes, but in very small areas," Nicholls said. "But they're important because lots of people live there."

The map below highlights just a few of the many rivers and canals within Jakarta. The combination of so many people and the multitude of rivers has made this city especially prone to relative sea level rise.

In the US, cities like New Orleans, which is near the Mississippi River delta, are also sinking. This correlates with one of the highest rises in relative sea level in the country.

According to NOAA, the greatest relative sea level rise has been measured near coastal Louisiana and southeastern Texas.

"A place where the combined effects of sinking land and sea level rise is in the northern Gulf Coast areas, like coastal Louisiana," said McNoldy, of the University of Miami.

In Galveston, Texas, sea levels have risen 6.62 mm per year or about one-quarter of an inch per year during the time period of 1957 to 2011. NOAA said this is "equivalent to a change of 2.17 feet in 100 years."

When asked what can be done about this issue, Nicholls said mitigating the threats of climate change is most crucial.

"I think the important thing is we have a great effort, and rightly so, to actually mitigating climate change and the Paris Agreement," Nicholls said.

The report also says reducing groundwater withdrawal and managing deltas can reduce land subsidence.

Pirates DFA reliever Tyler Bashlor to make space for infielder Wilmer Difo .
The Pirates are designating reliever Tyler Bashlor for assignment. The move opens 40-man roster space for infielder Wilmer Difo.Bashlor, 27, has pitched 62.1 MLB innings with the Mets and Pirates over the past three seasons. He has only a 5.78 ERA with poor strikeout and walk rates (18.5% and 12%, respectively) in that time. Bashlor has been much better in the minors, with a 1.63 ERA in 38.2 Double-A innings and a 3.41 mark in 37 frames at Triple-A.
