Will the Paris Agreement Be Stronger Without the United States?

The Paris agreement on climate change works for a delicate piece of magic.

The treaty aims to reduce global emissions of greenhouse gases, but does not legally require someone to stop emitting greenhouse gases. Instead, he advanced a set of loose and voluntary standards to reach the ultimate goal. By 2015, each country has announced a (non-binding) plan in which they promised (if applicable) to slow the pumping of carbon dioxide and methane into the atmosphere. In 2018, and every five years thereafter, all countries will meet and announce new commitments.

This madness was intentional. The architects of the agreement were hoping to push everyone to reduce their emissions altogether, but they did not (and could not) force any nation to do so. In particular, they could not force a Republican-dominated US Senate to ratify any binding international climate treaty. So Paris is dedicated to signs and not sacrifice; Resolutions unanimous, not top-down restrictions. John Kerry said that during negotiations he sends “literally, a fundamental message for the world market.” In truth, this is the only thing he did.

The Paris agreement worked as Barack Obama was president, and it is likely that he worked under the presidency of Hillary Clinton. A former United States head of state each year participate in the meeting to announce the importance of the document, and investors would receive the message and sink more money into infrastructure and research into renewable energy.

President Trump, however, speculated on the start of the treaty since its completion. If he remains in the treaty, he will lightly do so. This is why some climate leadership now wonder: the Paris agreement will be more difficult without the United States, at least as long as its president doubts about climate change?

Luke Kemp, a political scientist at the National University of Australia who has attended many climate talks, has been a speech in the conversation: “Money and emissions are all that matters.” (He made the same point in an article published in Nature Climate Change last week).

Neither money nor emissions will only change if the United States is actually a member of the Paris Treaty, he said. The agreements do not require the United States to participate in the Green Climate Fund, a United Nations reserve to help developing countries prepare for the consequences of global warming. Under Trump, this will not be the case.

More importantly, the agreement does not change the amount of gas retaining gas from America’s chimneys, exhaust pipes or farmland. Trump has already begun to weaken many national programs – such as the Obama Clean Energy Plan for the greenhouse electric sector and the CAFE standards for cars – that have added to the United States targets teeth in Paris. (Kemp argues that without them the country “probably will not achieve its climate goal”).
Kemp is also concerned about the effects of having the indolent United States dealt with at cascading meetings. If America loses its world goal – and nothing happens – the momentum that Paris will support will it separate? There are still many details about the treaty that however should not be finalized. Negotiators will spend time between 2020 and 2020 to devote themselves to the newspaper. If the United States continues, State Department Rex Tillerson will retain veto power in these talks. Does this weaken the treaty?

DNA from ancient Egyptian mummies reveals their ancestry

DNA from ancient Egyptian mummies reveals their ancestry

The ancient Egyptians were the dream of an archaeologist. They left behind complex coffins, huge pyramids and beautiful hieroglyphic code of pictorial writing was broken in 1799. The Egyptians recorded tales of royalty and gods. They took note of the blends of life, too, as much fun as the beer revenue and doctor notes.

But there was a persistent hole in ancient Egypt identity: its chromosomes. Fresh and dry permafrost can preserve prehistoric DNA as a natural freezer, but Egypt is a gene incinerator. The area is hot. In mummies’ graves, where scientists expected to find genetic samples, moisture was destroying their DNA. In addition, sodium carbonate and other chemicals used by Egyptian embalmers damage the genetic material.

A study by researchers at the Max Planck Institute for Science in the History of Humanity and the University of Tübingen in Germany has managed to connect some of these genetic deficiencies. The researchers destroyed the genetic material of 151 Egyptian mummies, radiocarbon dating New Kingdom of Egypt (the oldest to 1388 BC) to Roman times (the youngest to 426 AD), according to reports in the journal Nature Communications.

Johannes Krause, a paléogénétisme of the University of Tübingen and author of the study, said the main finding was that “during the year 1300, a complete genetic continuity is observed.” Despite the repeated conquest of Egypt by Alexander the Great, the Greeks, Romans, Arabs and Arab Assyrians – and the list goes on – the ancient Egyptians showed little genetic change. “The other big surprise,” said Krause, “if we do not have many sub-Saharan African ancestry.”

The remains were from Abusir el-Meleq, an ancient Nile community in the middle of Egypt. Mummies, scientists have extracted bone samples from teeth and soft tissues. (Although Egyptian embalmers had removed the brains of the deceased, scientists wrote that “in most cases, unmixed mother heads still retain much of their soft tissue.”)

Difficult samples produced most of the DNA, perhaps because the teeth and bones were protected by the soft tissues or because the hiring process leaves a hard material intact. After preparing the samples in a sterilized room in Germany, the researchers bathed the samples under UV rays for one hour to minimize contamination.
The ancient Egyptians were closely related to those living along the eastern Mediterranean, according to the analysis. They also shared the genetic material with the residents of the Turkish peninsula at the time and in Europe.

Given Egypt’s location at the intersection of Africa, Europe and Asia, and the influx of foreign leaders, Krause said he was surprised that genetics appeared to be stable during this period. Scientists are particularly interested in the change of the ruling class at the beginning of the first millennium. First, the Hellenistic dynasty, following the conquests of Alexander the Great, from 332 BC. In the year 30 BC. AD, then the Roman rule in 30 BC. In the EA does not seem to be bothered by the change policy of 400 AD However, genetics community Abusir el-Meleq.

Scientists compared the ancient DNA to that of modern Egyptians 100 and 125 modern Ethiopians previously analyzed. If you ask the Egyptians, who say they have recently become more European, said Krause. “We see exactly the opposite,” he said.

It is relatively recent in Egypt’s long history that sub-Saharan genetic influences have become more pronounced. “In the last 1500 years, Egypt has become more African, if you will,” said Krause.

In their article, the researchers acknowledged that “our genetic data were obtained from a single site in Middle Egypt and may not be representative of ancient Egypt.” In southern Egypt, the authors wrote that sub-Saharan Africa’s influences could summer stronger.

NASA to announce its first mission to ‘touch the Sun’ today

New Delhi, 31 May: In what is supposed to be a landmark in space science, the National Aeronautics and Space Administration (NASA) will officially announce its first mission to fly our sun directly into the atmosphere. Calling the first “touch the sun” mission, the space agency in its statement said it would make the announcement at 11 am EDT Wednesday (meaning HST 8:30 pm Wednesday). The announcement will be made at the Eckhardt Research Center William Auditorium at the University of Chicago. The official announcement reported that the event will be broadcast live on NASA television and the agency’s website.
NASA Solar Probe Plus (SPP) should be launched in the summer of 2018. The NASA spacecraft will be placed into orbit at least four million kilometers from the surface of the sun. In this orbit, the spacecraft will encounter heat and radiation, unlike any spaceship in history.
The sun is 93 million miles (about 150 million kilometers) from Earth. The connection and interaction between the Sun and Earth in car of the stations, the ocean currents, the weather, the climate, the radiation belts and the northern lights. Although it is special to us, there are a billion stars as our sun dispersed in the galaxy of the Milky Way. It is believed that NASA’s spacecraft to explore the outer atmosphere of the sun and make critical observations that answer questions about physics decennial how the stars work. The resulting data will improve the main meteorological forecasts weather phenomena that influence life on Earth, as well as satellites and astronauts in space.
According to reports, a block instrument of 370 kilograms (815 pounds) called Helios 2 arrived about 43 million kilometers (27 million miles) from the surface of the Sun in its mission to study the solar winds and the cosmic radiation in 1976. He was informed that NASA will be closer to the Helios 2 sun crown to improve understanding of the sun.
Participants will be part of NASA’s solar mission are Thomas Zurbuchen, associate director of the NASA Science Mission Directorate in Washington; Nicola Fox, scientific mission project at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, Eugene Parker, S. Chandrasekhar Distinguished Professor Emeritus Professor at the University of Chicago, Eric Isaacs, Executive Vice President Research, Innovation And the National Laboratories to the University of Chicago, Rocky Kolb, Dean of the Division of Physical Sciences at the University of Chicago.

Is the Great Barrier Reef now truly beyond saving?

Is the Great Barrier Reef now truly beyond saving?

Is the Great Barrier Reef now truly beyond saving?

Closed Tuesday, May 30, 2017, 17:39 – The Great Barrier Reef underwent major laundering of events, but it is the largest coral reef system in the world, really beyond all hope of ransom, as recently proclaimed Some titles

2016 and 2017 were very bad for the Great Barrier Reef. Due to rising ocean temperatures, the reef system, which lies along the northeastern coast of Australia, underwent two major whitening events in the last two years. As a result, the overall health of this important ecosystem has been threatened as a result, and further losses are expected in 2017.

The discoloration is the term used to describe how the warm waters of the ocean are like the corals expel the colored algae that provide them with a food source, so the white coral. This makes them vulnerable to diseases of corals, invasive algae species that do not benefit them, invasive populations of star coral and horn thorns unless ocean temperatures are beneficial enough that cold algae return opportunistic corals can starve.

The Australian government has launched since March 2015, the long-term 2050 Coral Sustainability Plan, which, at its core, a statement of how the “exceptional universal value” of the reef (as defined by the World Heritage Convention ) Was to increase every decade between the introduction of the plan and by the year 2050.

Recent scientific reef manifestations, however, were somewhat surprising.

Many caused damage to the reefs by these consecutive whitening events that the Coral 2050 plan simply is not enough to prevent the health of the reef system from continuing to decline.

This does not mean that scientists have placed the Great Barrier Reef in palliative care, waiting for the moment when it has died and gone.

First, for any sustainability plan for the reef at work, experts say the plan should take climate change into account and include measures to combat it. Currently, the Coral 2050 plan does not.

A panel of experts who assessed the level of Coral 2050 in early May, said:

“Members agreed that, in our lives and in our clocks, large areas of the Great Barrier Reef and surrounding ecosystems are significant long-term damage that may be irreversible if action is not taken now. Science informs us we are unprecedented in the history of mankind.Although this is in itself can be a cause of action, the extraordinary speed of the changes we observe makes the one action even more urgent. ”
“The Committee believes that measures to reduce greenhouse gas emissions should be essential to the response.This should be accompanied by increased efforts to improve the resilience of coral and other ecosystems that make up the Great Barrier Reef “On managing reefs to maintain the benefits offered by the reef.

At the recent Coral Summit, Townsville, Australia, these scientists have echoed this call to action.

“The last two years underscore the need to take urgent action to curb the decline of corals,” said Dr. Russell Reichelt, president of the Great Barrier Reef Marine Park Authority. “The Great Barrier Reef is a large, rugged system that has previously been shown to be capable of rebounding, but the current changes are undermining the reef’s resilience.”

“The Summit expressed deep concern about the need for global action to reduce greenhouse gas emissions, the engine of climate change.”

Second, however, while the Coral 2050 plan can not achieve its main objective, according to The Guardian, experts call for a much more achievable goal – maintaining the ecological function of the reef system.

Global Warming Will Cost Cities Twice As Much Thanks To ‘Heat Islands’

Global Warming Will Cost Cities Twice As Much Thanks To ‘Heat Islands’

Global Warming Will Cost Cities Twice As Much Thanks To ‘Heat Islands’

It is expected that global warming will have a major impact on the economy, and a new study suggests that cities will be the most difficult.

The study published Monday in the journal Nature Climate Change showed that the total economic costs of climate change for cities could be 2.6 times higher because of an effect researchers call the “urban heat island.”

The researchers examined 1692 cities and found that by the year 2100, they could be up to 8 degrees C warmer. Nearly 5 degrees would be due to global warming, but the rest comes from the heat island effect, which occurs when parks and lakes are replaced by concrete and asphalt.

Hot city

By 2050, cities could see temperatures rise two degrees from the islands of heat. This could mean more air pollution, poor water and poor health.

“Any hard-won victory over climate change in the world could be destroyed by the effects of uncontrolled urban heat islands,” Richard SJ Tol of the University of Sussex said in a statement.

The study found that the median city loses between 1.4% and 1.7% of GDP in 2050 and between 2.3 and 5.6% in 2100, according to the amount of heat that heats during this period. The poorest city could have losses of up to almost 11 percent of its GDP.

The researchers examined various policies that could mitigate the economic impact of global warming, such as planting more trees.

They found that the cheapest measure would be to install fresh ceilings and floors that absorb less heat and less reflected in the surrounding environment. The study found that modifying 20 percent of a city’s roofs and half of its sidewalks could save 12 times the cost of installation and maintenance and reduce the air temperature by 0.8 degrees.

Saturns moon Enceladus may have tipped over: study

New York, May 31 (PTI) Saturns icy, oceanic moon Enceladus may have been tilted in the distant past, probably due to a collision with a smaller body such as an asteroid, according to new data from the spacecraft Cassini of NASA.
The researchers found that the axis of rotation of the moons – the line through the north and south poles – has reoriented.
By examining the characteristics of the moons, the team showed that Elceladus seems to have been moved away from its original axis by about 55 degrees – more than half the way to the rolling completely on its side.

“We have found a chain of weak areas or ponds that trace a belt across the surface of the moons which we believe are the fossil remains of a previous and previous equator and poles,” said Radwan Tajeddine, a team Cassini imagery associated with Cornell University in the United States.
The area surrounding the ice moons of the current South Pole is a geologically active area where long, linear fractures, called stem bands, intersect across the surface.
Researchers speculate that an asteroid may have struck the region in the past when it was closer to the equator.
“It is unlikely that the geological activity in this terrain was initiated by internal processes,” said Tajeddine.
“We believe that, in order to lead such a large reorientation of the moon, it is possible that an impact is behind the formation of this abnormal terrain,” he said.
In 2005, Cassini discovered that jets of water vapor and ice particles sprayed tiger strip fractures – evidence that an underground ocean drains directly into space beneath the active south polar terrain.
Whether it is an impact or another process, the researchers stated that the disturbance and creation of the tiger strip terrain resulted in a redistribution of the Enceladus mass, making the rotation of the moons unstable And stifling.
The rotation would have finally stabilized, probably after more than a million years.
By the time the rotation has taken place, the north-south axis would have reoriented to cross different points of the surface – a mechanism called “true polar wandering”.
The idea of polar wandering helps explain why the North and South poles of modern Enceladus seem quite different.
The south is active and geologically young, while the north is covered with craters and looks much older.
The original poles of the moons would have looked more like the event that prompted Enceladus to move and relocate the disturbed terrain of the tiger strip in the polar south region of the moons …….

Butterfly Craters on Mars, Mercury, Moon Reveal Similarities and Differences

Butterfly Craters on Mars, Mercury, Moon Reveal Similarities and Differences

Unusual butterfly-shaped craters on Mars, Mercury and the Moon can give an overview of the three worlds surfaces, and even suggest the presence of a third window that could previously orbiting the red planet, new research shows.

Research comparing these butterfly features on the three objects in the solar system helps identify the similarities and differences of the body and to help scientists understand the conditions in the world where materials are crushed and insect models created.

“The combination of these two [features] gives us what looks like butterfly wings,” said Robert Herrick of the University of Alaska Fairbanks, at Space.com. Herrick has used up-to-date observations of Mars, Mercury and the Moon to make a more complete study of objects striking surfaces at low angles, forming butterflies and other unusual shapes. He presented his findings to the Conference of Lunar and Planetary Sciences in The Woodlands, Texas, in March.

NASA’s Viking orbiter collected images of crater butterflies on Mars in the 1970s while Apolllo missions have captured evidence of similar craters on the Moon in the 1960s and 1970s. The elongated body cratered craters did reveal low angles of batting, Which crashed on the ground at relatively low speeds. Slowly, as they rushed into the area, they blew the material into the air.

The ejection pattern in this Mars butterfly crater formed as blowing material created two “forbidden zones” ahead and behind the crater in which nothing returned to the surface. Resultant debris left a butterfly model.

But debris does not fall evenly around the site. Small footprint impacts and deceleration create “forbidden zones” or wedge-shaped regions through and beyond the object without introducing ejected material. While ejected greatly fall from the sides, the floor in front and behind the impactor remains free of debris. The result is the unusual shape of butterflies.

While laboratory experiments have recreated most forms of butterflies observed in nature with sufficient attention, Herrick said they are not perfect replicas. “We’re still working to understand what’s going on,” he said. Replication defects allowed in the lab is still a challenge, which is suspicious hardware Herrick-related surface, he said.

Material blown into the air by impact can melt or vaporize quickly, which affects how it falls on the ground. Herrick suggested that the presence of ice below the surface of Mars could affect how the materials fall to the surface around elongated craters. Detailed crater comments and their features can help resolve some of the mysteries surrounding them, he said.

During the decades since NASA’s Apollo and Viking missions, space agencies have sent out other missions to visit the three rocky worlds. Herrick looked at mercury images of NASA’s MESSENGER spacecraft as well as more detailed images of various missions to the Moon and Mars to extract a more complete list of the population of unusual craters. He compared some of the best preserved craters in them to see how the features differ in all three worlds.

Due to active erosion from wind and water (in the past) on Mars, more unusual craters on Mars degrade, Herrick said. However, because Mercury and the Moon have essentially no atmosphere, craters tend to remain longer virgins, he said. At the same time, Mars is the largest of the three bodies, and this affects the amount of gravitationally drawn to the surface of the material. Consequently, it has a larger population of elongated craters.

Happy New Year, Mars!

Happy New Year, Mars!

The scientists decided that some years ago, somewhat arbitrary, that the years of Mars begin the spring equinox in the northern hemisphere of the planet. Now spring has broken out.

Here on Earth, we are accustomed to the stations of the same length. But this is not the case on Mars, because most eccentric way red planet around the sun leads to different orbital speeds. On Mars, the spring and summer of 194 and 178 days, respectively, while the winter lasts 154 days and fell only 142 days, NASA officials said.

The Curiosity convertible car landed on Mars in August 2012, prompting a surface mission originally scheduled to last a Martian year. But curiosity continues to roll and is now exploring the foothills of Mount Sharp, which rises 5.5 km into the sky of the red planet.

Residents of the city of Mars, Pennsylvania, celebrate the new year with a festival of science of mars, technology, engineering and mathematics two days, NASA officials said in a statement. The festival lasts until Saturday (May 6).

The next opportunity for the Pennsylvania Martians to celebrate this way will only come March 23, 2019.
