Unprecedented: China launches ATV capable of climbing 70-degree slope and making 360-degree turn
People's Daily, China
Published on Sep 8, 2017

The research and design of all-terrain vehicle (ATV) “Bobcat” began in 2004 by Chen Jin, a PhD graduate in Mechanical Engineering from Tsinghua University. His task was to design a combat vehicle that could be transported by a helicopter and be able to fight in any terrains after landing. The first prototype is named “Bobcat”, because Chen wants it to be as sharp and flexible as a bobcat.

With eight wheels, “Bobcat” is able to make a 360-degree turn and climb a steep slope up to 70 degrees. Chen said “Bobcat” is a tank just with a smaller size.

Among over 800 car manufacturers in China, more than a half is able to produce military vehicles. Many countries are using world-class special purpose military vehicles that are made in China nowadays.

Plasma electric cooker from aerospace

2017-05-17 16:19:54

In February of this year, Shenzhen Yu Long Electric Co., Ltd. was formally established, and introduced the electric flame stove (also known as Yu Long plasma stove) to the public.

Plasma is often seen as a fourth state after the solid, liquid, and gas.

In addition to the flame stove, Lu Yu Long's team also started to develop plasma water heaters, plasma heaters and other technology products.


《中国达人秀》上,那个玩转特斯拉线圈的科学达人卢驭龙,还在朝着他的梦想一步步前进。

今年2月份,深圳驭龙电器有限公司正式成立,身兼CEO、CTO的卢驭龙,带着他的新作——驭龙电焰灶(也称驭龙等离子灶)再一次走进了公众的视野。

等离子体(plasma)又叫做电浆,常被视为是除去固、液、气外,物质存在的第四态。看似“神秘”的等离子体,其实广泛存在于宇宙中,例如常见的闪电,就是一种等离子态。卢驭龙与等离子技术,有着特殊的渊源:当年帮助卢驭龙夺得青少年科技创新大赛大奖的作品--晶体管式等离子弧双声道扬声器,就是一种等离子技术。与“通过改变调制信号的频率,使电弧发出的声音产生相应变化”的等离子弧扬声器不一样,如今的电焰灶,是通过高压等离子体弧光放电实现作业的。由于是通过电离空气介质进行作业,驭龙电焰灶颠覆了传统灶具,只要插电就可以产生跟明火一样的火焰,无需消耗燃料,真正做到安全清洁无污染,具有无比广阔的市场前景。

作为电学实验爱好者,卢驭龙并没有打算停下探索的脚步,成立深圳驭龙电器有限公司的初衷,是想通过科学技术,为人类的生产生活添砖加瓦。除了电焰灶,卢驭龙的团队还着手研发等离子热水器、等离子供暖器等科技产品,怀揣着年少时的梦想,当初的“闪电侠”在不断成长。

China building world’s biggest quantum research facility
Centre could boost military’s code-breaking ability and navigation of stealth submarines

China is building the world’s largest quantum research facility to develop a quantum computer and other “revolutionary” forms of technology that can be used by the military for code-breaking or on stealth submarines, according to scientists and authorities involved in the project.

The National Laboratory for Quantum Information Science will be located on a 37-hectare site next to a small lake in Hefei, Anhui province. Some time this month developers will be invited to bid for a contract to construct the site, according to an article in Hefei Evening News, a daily newspaper run by the city government on Thursday.

Pan Jianwei, China’s lead quantum scientist who was playing a key role in the project, told local officials at a briefing in May that technology developed in the facility would be of immediate use to the armed forces, according to Anhui Business Daily newspaper.

Quantum metrology, which measures small variations in physical parameters such as gravity with unprecedented accuracy, could significantly improve submarines’ stealth operations.

A submarine with a quantum navigation system could operate underwater for more than three months without the need to surface for positioning satellite signals.

After operating for 100 days underwater the captain would still be able to pinpoint the vessel’s position in the Pacific Ocean with a margin of error of just a few hundred metres according to Pan, who could not be immediately reached for comment.

f0a36984-9487-11e7-b116-f4507ff9df92_1320x770_223838.jpg

Another key mission of the laboratory is to build the nation’s first quantum computer that could break an encrypted message in seconds.

“Our plan is that by 2020, or maybe as soon as next year, to achieve ‘quantum supremacy’ with calculation power one million times to all existing computers around the world combined,” Pan was quoted as saying by Anhui Business Daily, which is run by the provincial government.

It was unclear whether the computer could be used for code-breaking.

Construction work is expected to finish in 2 ½ years with a budget of 76 billion yuan (HK$91.6 billion).

Ground-clearing work started with approval from the central government in February, according to the website of the Chinese Academy of Sciences, the owner of the new facility.

Guo Guoping, a quantum information researcher at the Chinese Academy of Sciences in Hefei, said

a large facility with centralised resources could accelerate this process by pulling together the talents of scientists from all over the nation with knowledge and experience of multiple scientific disciplines to overcome a wide range of technical and engineering hurdles, he said.

Guo stressed that in the national laboratory, researchers’ performance should not be evaluated by the scientific papers they published but by their contribution to specific project targets, such as building a general-purpose quantum computer.

“This may sound a bit old-fashioned, even Soviet-style, but it can give China a chance to win the race,” he added.

China moved a step ahead with the launch of a quantum satellite last year and conducted a series of cutting edge experiments such as quantum entanglement and teleportation in space.

Last month the world’s longest and most sophisticated quantum key distribution network for ultra-secure communication between Beijing and Shanghai was successfully tested and deemed ready for official deployment in the military, government and financial sectors.

Guo said the field had advanced rapidly, but the delivery of a code-breaking machine by 2020 was “highly unlikely”.

Over the next few years, researchers from around the globe may be able to develop primitive quantum computers to deal with some specific tasks.

They could, for example, simulate the movement of particles at a subatomic level to solve some physical problems that might help develop new materials or drugs.

But these are not general-purpose computers capable of code-breaking, Guo added.

(ECNS) -- Using 3D technology, a team lead by two Chinese ancient biology researchers has successfully printed a 3D model of a Placodermi's head, which will help further research on the ancient fish that lived in Australia approximately 400 million years ago.

Lu Jing, a researcher with the institute of Vertebrate Paleontology and Paleoanthropology who was in charge of the research, told Chinese media the joint China-Australia team spent the past year conducting detailed research on the Placodermi head fossil.

The size of a ping pong ball, with the thinnest point less than 0.1 mm, the fossil was discovered 30 years ago in Australia. However, few researchers had touched it because it was so fragile, Lu said.

Lu, together with Hu Yuzhi, a Chinese doctor, used micro-CT technology to scan the fossil in detail, and then virtually created several thousand cross sections of it, which Lu used to print a 3D model of the fish head.

"It took us more than three months to print the model," Lu said. The model was six times larger than the original fossil and was the first 3D model of an ancient fish in the world, according to Lu.

With the model, researchers could deconstruct and then put together the pieces to get first-hand information on the ancient fish. Some information might also help researchers uncover secrets about the human body.

Lu said she was planning to print 3D models of other Placodermi, and her research achievements had been shared with Chinese professionals. She said she hoped one day the models could be exhibited in museums, allowing every child the opportunity to touch them and learn about the ancient fish.

World’s 1st atmosphere observation system to be brought to Tibet
By Liu Caiyu Source:Global Times Published: 2017/9/11 23:13:40

The world's first complex atmospheric observation system will be brought to Southwest China's Tibet Autonomous Region before October to monitor the atmosphere, experts said Monday.

The Atmospheric Profiling Synthetic Observation System (APSOS) is capable of monitoring the atmospheric composition, such as temperature, wind, ozone and carbon dioxide levels through remote sensing, the Institute of Atmospheric Physics of the Chinese Academy of Sciences (CAS) said on its website.

"The system was debugged in Anhui Province's Huainan Atmospheric Physics (HAAS) and will soon be brought to the Yangbajain cosmic rays monitoring station in Tibet for extended atmospheric observation."

Located at 4,300 meters above sea level, the station is home to a host of many researches, including on cosmic rays.

APSOS is led by Lü Daren, a professor at the CAS' Institute of Atmospheric Physics, who told the Global Times Monday that "the system will be transported to Yangbajain station before October from Huainan city by trucks."

The system will be operational after at least one month of testing, Lü said.

"The system is the world first complex atmospheric monitoring equipment, which can continuously monitor multiple atmospheric components in a specific location. It can monitor up to 110 kilometers," Lü added.

Funded by the National Nature Science Foundation of China, the program was launched in 2012.

Lü said data collected by APSOS will be a worldwide achievement.

"Its data, together with data collected on the ground and through satellites from other countries, can support world atmospheric research."

APSOS will improve China's overall level of atmospheric environment detection, offer valuable data on weather conditions and space security, CAS said.

APSOS is composed of five laser radars, a millimeter-wave cloud radar, a terahertz superconducting radiation spectrometer and telescopes, and can detect precise air quality through multiband detection technology, CAS explained.

"The Yangbajain cosmic rays monitoring station was chosen as the site for APSOS due to its high altitude. The terahertz superconducting radiation spectrometer can only work in altitudes above 3,000 kilometers," Lu Hong, a professor at CAS' Institute of High Energy Physics, told the Global Times on Monday.

The terahertz spectrometer is capable of penetrating the air and detecting remote targets through, CAS said.

It also said the system will receive simultaneous changes in the atmospheric components of an area, and can also capture transient atmospheric processes through high temporal resolution. The data will help researchers understand how the atmospheric layer affects solar and human activity, it said.

Chinese astronomers reveal evidence of dynamical dark energy

2017-09-12 08:39

Xinhua Editor: Gu Liping

An international research team led by Chinese astronomers revealed an evidence of dynamical dark energy.

The discovery, recently published on Nature Astronomy, with a News & Views article written by a world expert on cosmology, found that the nature of dark energy may not be the cosmological constant introduced by Albert Einstein 100 years ago, which is crucial for the study of dark energy.

The new study was supported by the National Natural Science Foundation of China (NSFC), Chinese Academy of Sciences, and a Royal Society Newton Advanced Fellowship.

Revealing the nature of dark energy is one of key goals of modern sciences. The physical property of dark energy is represented by its Equation of State (EoS), which is the ratio of pressure and energy density of dark energy.

In the traditional Lambda-Cold Dark Matter (LCDM) model, dark energy is essentially the cosmological constant, i.e., the vacuum energy, with a constant EoS of -1. In this model, dark energy has no dynamical features.

In 2016, a team within the SDSS-III (BOSS) collaboration led by Prof. Gong-Bo Zhao of National Astronomical Observatories of China (NAOC) performed a successful measurement of the Baryonic Acoustic Oscillations (BAO) at multiple cosmic epochs with a high precision.

Based on this measurement and a method developed by Zhao for dark energy studies, the Zhao team found an evidence of dynamical dark energy at a significance level of 3.5 sigma. This suggests that the nature of dark energy may not be the vacuum energy, but some kind of dynamical field, especially for the quintom model whose EoS varies with time and crosses the -1 boundary during evolution, according to NAOC.

"As the Zhao team reported in this work, a dynamical dark energy model is able to naturally reconcile tensions between local and primordial measurements of cosmological parameters in the LCDM model," Prof. Xinmin Zhang at the Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences (CAS) told Xinhua.

"Which makes a crucial step towards understanding the nature of dark energy," he added.

The dynamics of dark energy needs to be confirmed by next-generation astronomical surveys. The team points to the upcoming Dark Energy Spectroscopic Instrument (DESI) survey, which aims to begin creating a 3D cosmic map in 2018.

In the next five to ten years, the world largest galaxy surveys will provide observables which may be key to unveil the mystery of dark energy, according to a news release of NAOC.

Research group discovers the origin of octopuses' instant modulation of body coloration
September 11, 2017 by Zhou Yijing

Cephalopods, the group of animals including octopus, squid, and cuttlefish, are famous for their remarkable ability to modulate body coloration and patterns instantly. With this ability, they can easily blend into surrounding environments or send warning signals to other animals. Reflectin, a protein that exists exclusively in cephalopods, is responsible for this structural color change. However, its origin and working mechanism are still unknown.

Researcher Xie Can from School of Life Sciences, Peking University, and his co-workers carried out a 5-year research and traced the origin of the reflectin gene back to a transposon from the symbiotic bioluminescent bacterium Vibrio fischeri. They hypothesized that a horizontal gene transfer (HGT) event introduced the reflectin gene into ancient cephalopods. In addition, the hierarchical structure of reflectin protein was reported. Activated by some chemical molecules and neurotransmitters, reflectin is able to form ordered structures swiftly. Moreover, the team also found that self-assembly and higher-order assembly in reflectin originated from a core repeating octapeptide, which may be from the aforementioned symbiotic bacteria, and named it "protopeptide."

The discovery was published online in Current Biology as the cover paper, with PhD Student Guan Zhe and Cai Tiantian as the co-first authors and Xie Can as the corresponding author.

Shanghai Synchrotron Radiation Facility

THE recently released “Construction Plan of Zhangjiang Science City” revealed that the high-tech park will become an administrative subdistrict, as part of a national strategy to establish Zhangjiang Comprehensive National Scientific Center.

According to the blueprint, Zhangjiang will have a central region along Chuanyang River, an artificial branch of Huangpu River, to be home to a batch of national-level laboratories and scientific projects along with various public services for employees and residents.

The science city has ambitions to be on a par with California’s Silicon Valley, Singapore’s One North Science Park and Japanese Tsukuba scientific town. And it will establish a basic framework for a comprehensive national scientific center by 2020.

To achieve that goal the world’s top innovative professionals, national scientific facilities, leading universities, research institutes and research and development centers of multinational enterprises will be looked at.

To make Zhangjiang a top attraction for talented researchers, the local government provides vigorous support with a series of complementary policies. Scientists will be ensured to receive excellent services and enjoy a supportive environment for research.

As part of the policies, around 9.2 million square meters of residential buildings will be built. About 96 percent of them will only be available for rental, according to the Shanghai Planning, Land and Resources Administration.

The first phase construction of apartments for rent will be launched at Sunqiao. As part of the future international community, it occupies an area of 65,000 square meters. A total of 1,226 well-furnished condos will be available after the construction is completed.

Subway and bus lines will run through the science city to connect office buildings, renovated factory houses and innovation parks for startups. More expressways to link to Shanghai’s railway stations, airports, and downtown areas have also been planned.

Schools and other public facilities will be built to serve residents, most of whom are scientists, research fellows, senior executives and their families.

The science city will be surrounded by a greenbelt. Continuous paths for walking and cycling along the Chuanyang River, small parks and public plazas will be built within the area.

It aims to attract 500 renowned scientists and experts by the end of 2020. Over 20,000 professionals from abroad and overseas graduates will work in Zhangjiang by then, according to the Pudong New Area government.

The authority has announced the establishment of the Administration of Overseas Talent to offer a one-stop service for overseas professionals along with a batch of new policies to ease green card and work permit rules.

The foreign talent recommended by the Zhangjiang or Shanghai Free Trade Zone management committee, for instance, can enjoy a fast track system to apply for the Chinese green card, or foreigners’ permanent residence cards, according to one of the new policies.

The application process can be shortened to two months from six months to receive the card. Spouses and children under 18-years-old can apply for the card at the same time.

China lags behind in global talent recruitment
By Zhao Yusha Source:Global Times Published: 2017/9/11 23:23:39

Govt should provide more incentives to foreign talent
China urgently needs more qualified international talent, with Shanghai the country's only city that enjoys global talent competitiveness above the world's average, a new report revealed.

Shanghai is the favorite Chinese city of foreign talent, said the report, released by the Center for China and Globalization (CCG) on Monday, followed by Beijing, South China's Guangdong Province and East China's Jiangsu Province.

Shanghai beat other cities and scored 65.17 out of 100 in global talent competitiveness, because of its openness, work environment, job opportunities and preferential policies.

"I finally chose to stay in Shanghai because it has more work opportunities than other Chinese cities, and the city's lifestyle is more international, which makes me feel more comfortable," said Juan, a Mexican electronics engineer who has worked in several other Chinese cities.

Surprisingly, East China's Jiangsu Province has more foreign talent than Beijing, the CCG report said.

Coastal province Jiangsu is home to many foreign companies because it's relatively developed and the environment is enjoyable and pleasant, Zhang Yunling, director of the Chinese Academy of Social Sciences' Institute for International Studies, told the Global Times.

The Jiangsu government has invested heavily to attract foreign talent, CCG vice secretary Zheng Qinglian said.

For instance, a medical park in Taizhou city gives each PhD holder an additional subsidy of 20,000 yuan ($3,070) and 150,000 yuan to buy a house, Jiangsu's official newspaper, Xinhua Daily, reported.

However, Wang Huiyao, head of Southwestern University of Finance and Economics' Institute of Development Studies, said China's global talent competitiveness still lags behind developed countries.

According to the 2017 Global Talent Competitiveness Index, a report produced by The Business School for the World (INSEAD), China ranks 54th in global talent competitiveness.

As a developing country, China faces the challenge of attracting international talent because it provides less work opportunities for foreigners than developed countries, and Chinese society is relatively more conservative, said Zhang, adding that foreigners also face cultural and language barriers.

Providing incentives

"China has a great potential to attract international talent," said Xie Shouguang, head of the Social Sciences Academic Press.

China is in a reasonably robust position of talent readiness because of improvements to its educational and employment system, connectivity of stakeholders, and level of technological competence, the INSEAD report said.

Many foreigners also complained that aside from cultural and language barriers, they also have a difficult time applying for a visa. Reforms have been implemented in different regions to correct this problem.

"It is impossible for fresh college graduates to apply for a work visa because the country requires two years of work experience," Jon, a Dane, who currently studies in Shanghai, told the Global Times.

The Shanghai government began a pilot program in 2015 that allows foreign students with a master's degree from Shanghai universities to start a business after graduating, the Xinhua News Agency reported.

In May, the Anhui government said that high-level foreign talent, their spouse and minor children, as well as overseas Chinese with PhD degrees who work in Anhui, can apply for permanent residency.

China invests in seismological study after major quakes
Source: Xinhua| 2017-09-12 15:54:54|Editor: Song Lifang



CHENGDU, Sept. 12 (Xinhua) -- Chinese science authorities will give special funding to support seismological research on plate tectonics in the country's earthquake-prone areas.

At a meeting on quake prevention and disaster reduction Monday, Zheng Guoguang, head of the China Earthquake Administration said funding up to 30 million yuan (4.6 million U.S. dollars) a year would go to the research program in the next five years.

The program, in effect from this month, is jointly sponsored by the administration, the Ministry of Science and Technology, the Chinese Academy of Sciences and the China National Natural Science Foundation.

Two strong earthquakes hit China in August, with one measuring magnitude 7 in Jiuzhaigou of southwest China's Sichuan Province, and the other measuring magnitude 6.6 in Bortala Mongolian Autonomous Prefecture in Xinjiang.

The Jiuzhaigou quake left at least 24 people dead and 493 injured.

Seismologists believe that the epicenter of the quake was located near three fault zones, with frequent seismic activity making the area earthquake-prone. They attributed the quake to northward movement on the Indochina block.

Zheng said the in-depth seismological research program would help scientists understand the rhythm of seismic activities and carry out quake risk assessments.

The program also includes anti-seismic building construction and quake information services.

World lags badly on targets to slash TB, HIV, obesity: study
September 13, 2017

Credit: CC0 Public Domain​

Not a single country, out of nearly 200 reviewed, was on track to meet the UN target of eliminating new tuberculosis infections by 2030, according to a global health review published Wednesday.


At the same time, less than five percent of countries were likely to reach the UN goal of reducing suicides, road deaths and child obesity by that date, and only seven percent would likely eliminate new HIV infections.

Overall, only a fifth of 37 health-related targets set under the UN's Sustainable Development Goals (SDGs), adopted in 2015, are likely to be met, said the review carried by The Lancet medical journal.

"A number of targets remained out of reach for most countries," the authors wrote.

Under the review, funded by the Bill & Melinda Gates Foundation, more than 2,500 researchers from around the world scored the health progress of 188 countries, and projected their trajectory to 2030.

The projections "underscore the need for dramatic, if not unprecedented, acceleration of progress to improve health outcomes, reduce risk exposure, and expand essential health services for all countries," the authors said.

They team found "considerable inequality" between projections for rich and poor countries.

High-income countries were forecast to meet 38 percent of the UN's health-related targets, compared to three percent for low-income states.

They also were not dealing with the same problems.

Poor countries fared poorly on maternal mortality, child stunting, malaria and environmental risks that affected rich nations less.

But when it comes to lifestyle problems, many high-income countries, including the United States, fared poorly on measures for suicide, alcohol abuse and homicide.

China improving, US not

Looking to the future, the review said efforts to eradicate malaria and reduce deaths of infants and pregnant women were among the most promising, with more than 60 percent of countries projected to meet UN goals for all three.

"On the basis of current trends, Kazakhstan, Timor-Leste, Angola, Nigeria and Swaziland were projected to have the largest overall improvements," the team said in a statement.

This was driven by cuts in child mortality and better access to health care, family planning and birth assistance.

Countries expected to lose ground—considering trends for child obesity and alcohol abuse—included Sri Lanka, Venezuela, Serbia and Ukraine.

The report named China and Cambodia among middle- and low-income countries deserving of "recognition for improving their citizens' lives".

The same countries—along with Rwanda, Equatorial Guinea, Laos and Turkey—recorded the biggest improvements in universal health care between 2000 and 2016, which translated into better vaccine coverage, as well as fewer child deaths and malaria infections.

The United States, on the other hand, joined Lesotho and the Central African Republic among countries showing "minimal improvement" in universal health care, said the team.

This is a controversial topic in the United States, where Donald Trump's administration is seeking to undo Barack Obama's expansion of health care coverage.

Singapore, Iceland and Sweden were the best-performing countries in terms of health-related Sustainable Development Goals, according to the review.

Somalia, the Central African Republic and Afghanistan ranked lowest.

The United States was rated 24th overall with poor marks for suicide, child sex abuse, alcohol abuse and homicide, wile China ranked 74th with low scores for air pollution, road injuries, poisoning, and smoking.

India was at number 127 with poor performance on air pollution, sanitation and acute childhood malnutrition.

The review was published ahead of the 72nd session of the UN General Assembly opening in New York Tuesday.

Is the Earth warming? The ocean gives you the answer

Humans have released carbon dioxide and other greenhouse gases, and the result is an accumulation of heat in the Earth's climate system, commonly referred to as "global warming". "How fast is the Earth's warming?" is a key question for decision makers, scientists and general public.

Previously, the global mean surface temperature has been widely used as a key metric of global warming. However, a new study published in AGU's Eos proposed a better way of measuring global warming: monitoring ocean heat content change and sea level rise. The authors come from a variety of international communities including China (Institute of Atmospheric Physics, Chinese Academy of Sciences), U.S.A. (NCAR, NOAA, and University of St. Thomas) and France (Mercator Ocean).

To determine how fast the Earth is accumulating heat, scientists focus on the Earth's energy imbalance (EEI): the difference between incoming solar radiation and outgoing longwave (thermal) radiation. Increases in the EEI are directly attributable to human activities that increase carbon dioxide and other greenhouse gases in the atmosphere. Extra heat trapped by increasing greenhouse gases mainly ends up in the oceans (more than 90% is stored there). Hence, to measure global warming, we have to measure ocean warming!

On the other hand, the amplitude of the global warming signal compared with natural variability (noise) defines how well a metric tracks global warming. This study shows that the temporal evolution of ocean heat content has relatively high signal-to-noise ratio; therefore, it requires 3.9 years to separate the global warming trend from natural variability. Similarly, for sea level rise, 4.6 years are sufficient to detect the climate change signal. By contrast, owing to weather, El Niño - Southern Oscillation and other natural variability embedded in the global mean surface temperature record, scientists need at least 27 years of data to detect a robust trend. An excellent example is the 1998-2013 period, when energy was redistributed within the Earth's system and the rise of global mean surface temperature slowed - sometimes call a "hiatus".

This study suggests that changes in ocean heat content, the dominant component of Earth's energy imbalance, should be a fundamental metric along with sea level rise. Based on the recent improvements of ocean monitoring technologies, especially after 2005 through autonomous floats called Argo, and advanced methodologies to reconstruct the historical ocean temperature record, scientists have been able to quantify ocean heat content changes back to 1960, even though there is a much sparser historical instrument record prior to 2005. Sea level rise is best known since 1993 when altimeters were first launched on satellites to enable sea level change observations to millimeter accuracy.

According to the most up-to-date estimates, the top-10 warmest years of the ocean (indicated by OHC change at upper 2000m) are all in the most recent decade after 2006, with 2015-2016 the warmest period among the past 77 years. The heat storage in the ocean amounts to an increase of 30.4×1022 Joules (J) since 1960, equal to a heating rate of 0.33 Watts per square meter (W m-2) averaged over the entire Earth's surface-- and 0.61 W m-2 after 1992. For comparison, the increase in ocean heat content observed since 1992 in the upper 2000 meters is about 2000 times the total net generation of electricity by U.S. utility companies in 2015.

It is evident that scientists and modelers who seek global warming signals should track how much heat the ocean has stored at any given time, i.e. ocean heat content, as well as sea level rise. Locally, in the deep tropics, ocean heat content directly relates to hurricane activity. Ocean heat content is a vital sign of our planet and informs societal decisions about adaptation to and mitigation of climate change.
