The Gulf Stream is the weakest it’s been in 1,600 years – here’s why that’s really bad news

The Gulf Stream current, which serves as an important regulator of weather and climate along the Atlantic Ocean, is now the weakest it has been in at least 1,600 years. This dramatic slowing of the current, known as the Atlantic Meridional Overturning Circulation (Amoc), could usher in extreme shifts in weather patterns, such as more brutal European winters, rapid sea level rise on the American East Coast , and the disruption of essential tropical rainstorms. Suddenly, the 2004 climate-change disaster film The Day After Tomorrow, which depicted the dramatized consequences of a Gulf Stream slowdown, seems less science fiction, more predictive of a future plagued by catastrophic climate change. Although scientists have been aware of Amoc’s slowdown since 2004, two recent studies paint a more complete picture of just how dramatic this weakening has been. “The [current] climate models don’t predict [an Amoc shutdown] is going to happen in the future,” Dr. David Thornalley, leader of one of these recent studies published in the journal Nature , told the Guardian . “The problem is how certain are we it is not going to happen? It is one of these tipping points that is relatively low probability, but high impact.” Thornalley’s team gathered and analyzed sediments from North Carolina ‘s Cape Hatteras, as well as shells of marine animals at various Atlantic sites, to determine the full impact of the current slowdown. The study concludes that climate change has played at least a significant role in the weakened Amoc. Related: The Great Pacific Garbage Patch is growing at an exponential rate Also published in Nature , the second study used thermometer data from the past 120 years to reach a similar conclusion: Amoc is about 15 percent weaker than it was in 400 AD. While the second study places much of the blame on climate change , the first study also cites natural climate variability as a contributing factor to Amoc’s slowdown. Regardless of its causes, the weakening is recognized in both studies as a potentially destabilizing phenomenon. “If we do not rapidly stop global warming, we must expect a further long-term slowdown of the Atlantic overturning,” second study co-author Alexander Robinson told the Guardian . “We are only beginning to understand the consequences of this unprecedented process – but they might be disruptive.” Via The Guardian Images via Depositphotos (1 , 2)

Comments Off on Boeing’s new hypersonic plane could circle the globe in 3 hours

Boeing has developed a hypersonic plane that is faster than a speeding bullet. So fast, in fact, that it could circle the globe in just three hours, according to the manufacturer. The plane is designed to use its own shockwaves to increase its speed, and it could herald an entirely new era of flight. The plane was revealed last month, though we are just now getting real details about what it is like. The hypersonic plane is a ‘waverider’ style, which means that it uses the shock waves it creates to increase its speed. It is being developed as a reconnaissance or strike plane, and if it enters production, it will be the fastest plane ever produced, hitting speeds of Mach 5 or higher (that’s a mind-bending 3,836 mph). The development of a hypersonic plane could change the way we engage in warfare, because it means that a threat could arrive so quickly, there would only be minutes to identify it and prepare a defense. It also means that if it were developed as a passenger plane you would be able to travel anywhere across the Atlantic in an hour, and anywhere across the Pacific in two hours. It would go more than twice as fast as the Concorde . Related: Skreemr concept jet aims to fly 5 times as fast as the Concorde Aviation fans are calling the unmanned aircraft “Son of Blackbird,” because it is expected to be the successor of the legendary Lockheed Martin-developed Blackbird SR-71 plane. Some people speculate that it is being called “Valkyrie II” within the industry. Lockheed Martin and Boeing have been locked in a battle to develop hypersonic travel. Lockheed Martin has also been developing its own hypersonic plane, called the SR-72. Only time will tell who breaks the speed barrier first.

Humans have already dumped 400,000 pounds of trash on the Moon

Comments Off on Humans have already dumped 400,000 pounds of trash on the Moon

Pollution isn’t just Earth’s problem anymore. Despite not having established a permanent lunar residency, humans have already managed to dump 400,000 pounds of trash on the Moon . Much of this debris has been left behind over the twelve trips by humans to the lunar surface. Earthbound scientists figured out long ago that bringing the lunar visitors home would be cheaper and simpler if as much equipment as possible were left behind. Add in debris accumulated over unmanned missions and we have ourselves something of a lunar junkyard orbiting overhead. It’s important to remember that the trash we have left behind on the Moon does not exist in a vacuum. There is an enormous amount of space waste floating around our planet. Over 21,000 pieces of trash, from spacecraft fragments to disabled satellites, orbit the Earth. Most of the Moon’s trash was the result of crashed spacecraft , of which there are over 70. The remainder of the debris is a mish-mash oddly documenting humanity’s short lunar tenure. Because it is easier to return to Earth with as little weight as possible, each moon landing has permanently dropped a 22,700-pound Lunar Lander on the surface, as well as other modules, craft, or miscellaneous materials associated with that particular mission. Waste from low-gravity golf games as well as literal human waste (all 96 bags of it) litter the Moon’s face. Related: Super blue blood moon eclipse to occur next week for the first time in 150 years To be fair, we haven’t left only waste. A small aluminum memorial left by the crew of Apollo 15 to honor fallen astronauts stands on the silent lunar landscape. The feather dropped in Apollo 15’s “hammer-feather drop” experiment also remains. Even though the Apollo 1 mission never made it to the Moon, as it was shut down prematurely after three astronauts were killed during a training exercise, a patch from the unlaunched mission found its way to the lunar surface too.

Trump plan to reduce marine monuments could put vital ecosystems at risk

Comments Off on Trump plan to reduce marine monuments could put vital ecosystems at risk

A report from United States Secretary of the Interior Ryan Zinke recommends shrinking three ocean monuments and opening them up to commercial fishing . The monuments, two in the Pacific Ocean and one in the Atlantic Ocean , are undersea treasures, according to the National Oceanic and Atmospheric Administration’s administrator between 2009 and 2013, Jane Lubchenco, who told The Guardian , “These ‘blue parks’ harbor unique species, a wealth of biodiversity , and special habitats.” President Donald Trump may not just take aim at land-based national monuments , but at the following three marine monuments. The over 490,500-square-mile Pacific Remote Islands monument, created by George W. Bush and expanded by Barack Obama, includes largely untouched coral reefs and is “the last refugia for fish and wildlife species rapidly vanishing from the remainder of the planet,” per the Fish & Wildlife Service . The 10,156 square mile Rose Atoll monument “protects diverse marine ecosystems and the millions of wildlife dependent upon the Central Pacific.” And the 4,913 square mile Northeast Canyons and Seamounts monument is the United States’ only protected area in the Atlantic Ocean, featuring underwater mountains and canyons, deep-sea coral, and endangered whales and sea turtles. Related: Patagonia is suing the Trump administration over Bears Ears: “The President Stole Your Land” In his report Zinke said, “While early monument designations focused more on geological formations, archaeological ruins, and areas of historical interest, a more recent and broad interpretation of what constitutes an ‘object of historic or scientific interest’ has been extended to include landscape areas, biodiversity, and viewsheds.” Fishing organizations aren’t always pleased about the monuments. In March, a New England coalition sued the federal government over fears fishers would be out of a job due to the Northeast Canyons and Seamounts monument. The challenge is based on the idea Obama exceeded his authority in designating the monument. Conservation groups worry activities like seabed mining or oil drilling could be next if monuments are opened for fishing. Pew Charitable Trusts Director of U.S. Oceans, Northeast Peter Baker told The Guardian, “It shouldn’t be too much to ask to protect two percent of the U.S.’s exclusive economic zone off the Atlantic coast for future generations.” Lubchenco said, “Creation of highly protected blue parks like these monuments is beginning to re-establish the all-important balance of places to be used and places to be treasured. We need both.” Via The Guardian Images via USFWS – Pacific Region on Flickr and NOAA photo by Hatsue Bailey

Comments Off on "This is unprecedented": Irish Minister of State for Flood Relief on tropical storm Ophelia

When you hear the word ‘ hurricane ,’ you probably don’t think about Ireland . But Tropical Storm Ophelia, which has been downgraded from its status as a hurricane, is on a path towards the country, with warnings of high seas, power outages , and hazardous conditions. Minister for Flood Relief Kevin Moran said at a Dublin press conference, “This is unprecedented.” An Atlantic hurricane has been whirling towards the United Kingdom . Although Ophelia is an ex-hurricane, the Irish Meteorological Service, Met Éireann , is warning of violent and destructive wind gusts that could reach between 120 and 150 kilometers per hour (km/h), or around 75 to 93 miles per hour (mph). They said heavy rain and storm surges in some coastal areas will lead to flooding , posing a danger to human property and lives. Related: How Hurricane Irma changed the colors of these Caribbean islands As many as 100,000 homes and businesses in the country have lost power, as power lines have been knocked down. An Electricity Supply Board spokesperson said earlier today many of the power lines are still live and asked people to stay away. The Met Éireann said at Cork Airport, wind gusts of 124 km/h, or 77 mph, were recorded; at Fastnet Rock wind gusts were 176 km/h, or 109 mph. The United Kingdom Met Office issued an amber weather warning for Northern Ireland, southwest Scotland, Strathclyde, and Wales. They issued yellow warnings for 11 locations, including western areas in England and Yorkshire. A status red weather warning applies to all cities and counties in Ireland, according to prime minister Leo Varadkar, who told people to stay indoors. Speaking of Debbie, the largest storm recorded in the history of Ireland in the 1960’s, he said, “The last time we had a storm this severe 11 lives were lost so safety is our number one priority.” Via The Guardian Images via NOAA/NASA Goddard Rapid Response Team and Met Éireann on Twitter

Huge battery in the UK holds the energy equivalent of 500K smartphone batteries

Comments Off on Huge battery in the UK holds the energy equivalent of 500K smartphone batteries

A large new battery storage project could help the United Kingdom’s grid handle power from more renewable sources . The 10 megawatt (MW) lithium-ion battery , on the grounds of a biomass plant in Sheffield, is contained inside four 40-foot shipping containers . It can hold the same amount of energy as around 500,000 smartphone batteries. UK energy company E.ON installed the battery , called the Blackburn Meadows battery for its location at the Blackburn Meadows biomass plant, and connected it to the grid . They said in their statement the battery has the same power as around 100 family cars. Related: Tesla nears halfway mark on world’s largest battery installation in South Australia The Blackburn Meadows battery is one of the first of what The Guardian described as a fleet of industrial-scale battery plants. National Grid, the firm that owns England and Wales’ electricity transmission network, requested new technologies to help keep the grid balanced, a challenge as more renewable sources come online – since the sun doesn’t always shine and the wind doesn’t always blow. The large batteries are a response to that request. When supply is high, the batteries can store power, and when supply drops, they can provide power. National Grid commercial development manager Leon Walker said in a statement, “Using battery storage is a significant development for managing the national grid. It’s an ultra-fast way of keeping electricity supply and demand balanced. Over four years we estimate that this service will save the system operator around £200 million.” While the Blackburn Meadows battery is currently one of the largest in Britain, The Guardian pointed out it won’t be long before others even bigger are built. They said British Gas’ parent company Centrica is building a 49MW battery facility, and EDF Energy is also building one that’s the same size. Their article included a graphic saying renewables provided almost 30 percent of the UK’s power between April and June of this year. Via The Guardian and E.ON Images via E.ON and Darren Cool / E.ON

Three hurricanes form in the Atlantic for the first time since 2010

Comments Off on Three hurricanes form in the Atlantic for the first time since 2010

While Hurricane Irma barrels through the Caribbean towards the United States mainland, another two potentially powerful storms are waiting in the wings. Following closely behind Irma, one of the strongest hurricanes recorded in the Atlantic, are Tropical Storms Jose and Katia. The presence of these storms marks the first time since 2010 that three active hurricanes have formed in the Atlantic. In what may prove to be one of the most active on record , the 2017 Atlantic hurricane season has already demonstrated the unpredictable and explosive power of storms in the age of climate change . Jose, like Irma, is known as a Cape Verde hurricane for its origins in the far eastern Atlantic , near the island nation of Cape Verde off the coast of Africa . However, it is unlikely that Jose will follow Irma’s path nor will it likely be as powerful. Jose is expected to spin towards the open ocean and become a Category 3 hurricane, though it is not expected to travel over any land area. Related: Harvey forces National Weather Service to add new color to its rainfall map Katia is more closely related to Harvey, in that it too became a hurricane in the warm waters of the southern Gulf of Mexico. Despite its shared birthplace with the devastating hurricane that made landfall near Houston , Katia is expected to travel close to Mexico . It is currently nearly 200 miles northeast of Veracruz, Mexico, near which a small portion of the coast is currently under hurricane watch. Although three hurricanes active in the Atlantic at the same time is unusual, it is neither unprecedented nor unrivaled. During the 1998 Atlantic hurricane season, four hurricanes, including Hurricane Georges which caused major damage in Haiti and the Dominican Republic , were active during the same period.

NASA captured an astonishing video of Hurricane Irma from space. Soon after the National Hurricane Center upgraded Irma to a Category 5 storm , the International Space Station’s external cameras caught what NASA described as a dramatic view of the hurricane . Irma has already smashed records – meteorologist Philip Klotzbach said on Twitter earlier this morning Irma has broken the Atlantic record previously held by 1980’s Hurricane Allen for Accumulated Cyclone Energy produced during 24 hours. Hurricane Irma is currently moving over Caribbean islands, and looks to be en route to Florida with winds reaching up to 185 miles per hour. As the International Space Station orbited the Earth, the station’s cameras shot the hurricane from multiple angles, showing how truly massive it is. According to weather forecaster Liam Dutton , Hurricane Irma is so large it would cover both Ireland and the United Kingdom. Related: Category 5 Hurricane Irma is one of the most powerful Atlantic hurricanes ever Most of the people on Antigua and Barbuda lost power, and in Antigua around 1,000 people spent the night in shelters, according to ABS TV and Radio director of news Garfield Burford.

Japan’s new mushroom solar farms produce sustainable energy and food

Comments Off on Japan’s new mushroom solar farms produce sustainable energy and food

Japan’s agricultural sector could find a much-needed boost with an innovative approach to growing that combines solar power generation and mushroom cultivation. Sustainergy , a Tokyo -based renewable-energy startup, in collaboration with Hitachi Capital and Daiwa House Industry , is determined to generate a total 4,000 kilowatts of solar power on two underutilized farm sites in Japan. Not only would the 2,000 kw output at each site stand as the largest of any similar facility in the country, the solar sites will serve another agricultural purpose: the cultivation of cloud-ear mushrooms, which require little sunlight, underneath the solar panels. In previous years, a reduced feed-in tariff kept potential entrepreneurs from seeking to convert land for solar purposes. However, in 2013, regulations were relaxed to ease the transition, though the government continued to insist that this land still be used for agriculture in some form. As Japan’s workforce ages and its young people primarily move into urban areas for job opportunities, much of the country’s farmland is unused, with some estimates claiming that about 10 percent of agricultural land is abandoned. If all of Japan’s abandoned agricultural spaces were converted to include solar power generation, the Ministry of Environment estimates that these projects could generate 70,000 megawatts, which would be enough energy to power 20 million households. Related: These amazing zero-waste buildings were grown from mushrooms 1.2 billion yen ($11 million) will be invested in the initial mushroom-solar sites in Miyagi Prefecture in northeast Japan. If this project proves successful, the collaborating companies plan to open up the concept to farmers and utilities across Japan, with Hitachi Capital providing panels and equipment to farmers for free, to start. This would allow farmers to become self-sufficient in their energy needs and earn a supplemental income. Additionally, mushroom cultivation would prove to be a big boost for local food; most cloud ear mushrooms consumed in Japan are currently imported from China . The solar-mushroom farms are expected to yield 40 tons of edible mushrooms while the power generated could be sold annually for 140 million yen ($1.27 million).
