Sea Salt Discovered on Jupiter’s Moon Europa

This image shows a view of the trailing hemisphere of Jupiter's ice-covered satellite, Europa, in approximate natural color. Long, dark lines are fractures in the crust, some of which are more than 3,000 kilometers (1,850 miles) long.   Image via Galileo spacecraft in 1996.

Europa is thought to have a subsurface ocean. Salt from this hidden sea might be emerging in long fractures visible in the moon’s crust.



Excerpt earthsky.org


Laboratory experiments have lead to new information about the chemical composition of the mysterious dark material in the long, dark fractures on the surface of Europa, a large moon of Jupiter. Researchers at NASA’s Jet Propulsion Laboratory (JPL) mimicked conditions on Europa’s surface. They now say that the dark material is discolored salt, likely sea salt from below the moon’s icy crust. The journal Geological Research Letters published their study on May 15, 2015.

The scientists say this new insight is important in considering whether this icy moon might be hospitable for extraterrestrial life. The life question is a key one for Europa, since this world is believed to have a liquid ocean beneath its crust. The presence of sea salt on Europa’s surface suggests the ocean is interacting with its rocky seafloor.

Scientists have been intensely curious about Europa since Galileo discovered it in 1610. In recent years, they’ve puzzled over the dark material coating the long, linear fractures on Europa’s observable surface. The material was associated with young terrain on this moon of Jupiter, suggesting that it had erupted from within Europa.
However, the chemical composition of the dark material remained elusive, until now.
Planetary scientist Kevin Hand at JPL led the new study. He said in a statement:
If it’s just salt from the ocean below, that would be a simple and elegant solution for what the dark, mysterious material is.
Europa is immersed radiation from Jupiter’s powerful magnetic field, causing high-powered electrons to slam into the moon’s surface. Hand and his team created a laboratory test that mimicked the conditions of Europa’s temperature, pressure, and radiation exposure. They tested a variety of samples including common salt – sodium chloride – and salt water in a vacuum chamber at Europa’s chilly surface temperature of minus 280 degrees Fahrenheit (minus 173 Celsius). They also bombarded the samples with an electron beam to imitate Jupiter’s influence. 

After several hours – a time period corresponding to over a century on Europa, the researchers said – the salt samples were observed to go from white to a yellowish brown, the color similar to the features on the icy moon. Hand said:
This work tells us the chemical signature of radiation-baked sodium chloride is a compelling match to spacecraft data for Europa’s mystery material.

Until now, telescopic observations have only shown glimpses of irradiated salts. No telescope on Earth can observe Europa’s surface with enough resolution to identify them with certainty. Researchers suggest additional spacecraft observation to gather more evidence.
A visit to this icy world would help answer the most tantalizing questions about Europa. Long believed to have a liquid ocean of salt water below its icy surface, this moon continues to display promising conditions for extraterrestrial life. 

As Europa orbits Jupiter, it experiences strong tidal forces similar to Earth and the Moon. These forces from Jupiter and the other Jovian moons cause Europa to flex and stretch, which creates heat, and results in Europa having a warm internal temperature than it would with just the heat from the Sun alone. 

Recent observable geological activity also creates strong evidence that the subsurface ocean interacts directly with Europa’s rocky interior, making geothermal vents, like those in Earth’s oceans, a strong possibility as well. 

These hydrothermal vent ecosystems on Earth thrive with no energy from the sun. Bacteria, shrimp and crustaceans have all been observed in these extreme environments, surviving on what researchers have deemed chemosythesis.

With Europa’s enormous amount of liquid salt water, essential chemical elements and geological activity, this long discovered icy moon appears to be one of the solar systems most promising locations for habitable requirements for life. 

However, until a devoted spacecraft visit’s, nothing beyond hopeful speculation can be proven, the researchers say.

Bottom line: Researchers at NASA’s Jet Propulsion Laboratory created laboratory conditions that mimicked those on Jupiter’s large moon Europa, to learn the chemical compositions of the material in long, dark fractures in the moon’s surface. They now believe this material is sea salt, which has emerged to Europa’s surface from its liquid ocean below.

Here’s Why Tesla’s Battery Is A Big Deal


Excerpt from forbes.com

It’s more about where the market and product are going than where they are today. Think about a complementary system of components:

  1. The big grid – always on, highly reliable power which is expensive during peak demand hours, i.e. when a family actually wants to use the power. But usually the electricity is cheap at night when no one wants to use it and those big baseload plants that are hard (or very hard in the case of nuclear) to slow down are still pumping out power. And sometimes that power is provided by strong night winds.
  2. Home solar – Don’t forget that Tesla’s CEO, Musk, is also Chairman of SolarCity which provides zero down leasing. Home solar is often poorly aligned to peak usage, with installers looking for maximum generation with south-facing solar panels rather than maximum generation during peak with south-west facing panels. Then there are the homes with roofs that are poorly aligned to the sun regardless, so imperfect generation is all that is possible. And that peak generation isn’t necessarily perfectly aligned with peak cost of grid electricity either, but merely overlaps with it.
  3. Home storage – Maximum generation alignment of home solar matters less when you can carry forward the unconsumed electricity from solar panels to your evening of cooking, washing dishes, washing clothes, and streaming Netflix on your 40″ tv. And cheap electricity you can store at night and consume when electricity is really expensive is valuable as well.
So these components exist, but to be fair, they existed before Tesla got into the home storage business and have for a long time. And Tesla’s offering costs about twice as much as more typical lead-acid batteries commonly used for the purpose. So why is this particular home storage battery getting so much attention?
  1. Hype – Don’t underestimate the marvel that is Musk’s ability to get attention. The man is a rock star of event unveiling.
  2. Net metering – Right now, there is a lot of conflict between utilities and home solar users and installation companies. Net metering is the requirement that home solar generators get paid for electricity that they produce and pump into the grid, and only pay for the electricity that they draw from the grid. Output vs input is the net. Home solar used to be an advantage to utilities — reduced peak demand — but has become a liability — reduced or even negative revenue from users of the grid. Basically, utilities still have to pay for the grid which home solar generators use, then they lose revenue or outright pay the home solar generator who is getting use of the grid for free. Since utilities pay for the grid out of electricity revenue, they are starting to demand that people with home solar who aren’t paying much for electricity start paying for grid usage to make up for it. This is getting mixed reviews, as you can understand, but in the USA especially is leading to a desire by many to be completely grid free, a dubious value proposition. Tesla’s hype fell into an emerging market opportunity of people who had solar on their roof, didn’t have batteries but are worried that they’ll be forced to pay more.
  3. Time-of-use billing – Combined with smart meters, time-of-use billing is becoming much more common in utilities in the developed world. This model is simple: reduce demand during peak periods by increasing the price, typically combined with incenting shift of demand to off-peak times by lowering the price. Flattening demand curves, especially peaks, is very advantageous for grid managers because they have to have capacity for the peak. This enables storage to time-shift consumption and save at least some money.
  4. Design – Previous storage units are collections of lead acid batteries, basically the same thing you have in your car, but scaled vertically and horizontally. They aren’t pretty, they are heavy, they take up floor space, they require maintenance, and they are pretty much a toxic addition to homes if breached or even if the tops are removed. Tesla’s model is sleek, hangs on a wall and is much more chemically inert with no liquids. It’s a benign home appliance as opposed to an industrial object (much as some people like the industrial aesthetic at home, it’s less common).
  5. The Gigafactory – What Tesla has going for it is that it is building the world’s largest battery factory, and likely expanding it now that the storage line has taken off so brilliantly. Pretty much everyone paying attention knows that Tesla is already producing batteries much more cheaply on a per KWH capacity at greater volume, and the Gigafactory is going to ramp that up. Battery storage has been dropping in price per KWH of capacity for a long time, but it’s closing in on a cusp point where it’s going to be worth it for average consumers to store at least some electricity.
What all of this adds up to is that home battery storage isn’t economical today, but it’s viable for a subset of the high-consuming market, it’s desirable for its green credentials, it’s desirable due to the hype factor and it will defray its costs. And that the home storage market tomorrow will be viable for a much larger percentage of the market with increasing systemic pressures and pricing that will make it more attractive. Tesla’s home storage battery is getting attention because they are staking a major claim to a market which is expected to increase dramatically.

Neanderthals Turned Eagle Talons Into ‘Stunning’ Jewelry


Image: Talons
The eight eagle talons from Krapina were arranged with an eagle phalanx that was also found at the site.


Excerpt from nbcnews.com

Long before they shared the landscape with modern humans, Neanderthals in Europe developed a sharp sense of style, wearing eagle claws as jewelry, new evidence suggests. 

Researchers identified eight talons from white-tailed eagles — including four that had distinct notches and cut marks — from a 130,000-year-old Neanderthal cave in Croatia. They suspect the claws were once strung together as part of a necklace or bracelet.


"It really is absolutely stunning," study author David Frayer, an anthropology professor at the University of Kansas, told LiveScience. "It fits in with this general picture that's emerging that Neanderthals were much more modern in their behavior." 
The talons were first excavated more than 100 years ago at a famous sandstone rock-shelter site called Krapina in Croatia. 
There, archaeologists found more than 900 Neanderthal bones dating back to a relatively warm, interglacial period about 120,000 to 130,000 years ago. They also found Mousterian stone tools (a telltale sign of Neanderthal occupation), a hearth, and the bones of rhinos and cave bears — but no signs of modern human occupation. Homo sapiens didn't spread into Europe until about 40,000 years ago. 
The eagle talons were all found in the same archaeological layer, Frayer said, and they had been studied a few times before. But no one noticed the cut marks until last year, when Davorka Radovcic, curator of the Croatian Natural History Museum, was reassessing some of the Krapina objects in the collection. 
The researchers don't know exactly how the talons would have been assembled into jewelry. But Frayer said some facets on the claws look quite polished — perhaps made smooth from being wrapped in some kind of fiber, or from rubbing against the surface of the other talons. There were also nicks in three of the talons that wouldn't have been created during an eagle's life, Frayer said.
The findings were published March 11 in the journal PLOS ONE.

Archaeologists find two lost cities deep in Honduras jungle

Excerpt from theguardian.com


Archaeological team say they have set foot in a place untouched by humans for at least 600 years in a site that may be the ‘lost city of the monkey god’

Archaeologists have discovered two lost cities in the deep jungle of Honduras, emerging from the forest with evidence of a pyramid, plazas and artifacts that include the effigy of a half-human, half-jaguar spirit.
The team of specialists in archaeology and other fields, escorted by three British bushwhacking guides and a detail of Honduran special forces, explored on foot a remote valley of La Mosquitia where an aerial survey had found signs of ruins in 2012.
Chris Fisher, the lead US archaeologist on the team, told the Guardian that the expedition – co-coordinated by the film-makers Bill Benenson and Steve Elkins, Honduras and National Geographic (which first reported the story on its site) – had by all appearances set foot in a place that had gone untouched by humans for at least 600 years.
“Even the animals acted as if they’ve never seen people,” Fisher said. “Spider monkeys are all over place, and they’d follow us around and throw food at us and hoot and holler and do their thing.”
“To be treated not as a predator but as another primate in their space was for me the most amazing thing about this whole trip,” he said.
Fisher and the team arrived by helicopter to “groundtruth” the data revealed by surveying technology called Lidar, which projects a grid of infrared beams powerful enough to break through the dense forest canopy.

That data showed a human-created landscape, Fisher said of sister cities not only with houses, plazas and structures, but also features “much like an English garden, with orchards and house gardens, fields of crops, and roads and paths.”
In the rainforest valley, they said they found stone structural foundations of two cities that mirrored people’s thinking of the Maya region, though these were not Mayan people. The area dates between 1000AD and 1400AD, and while very little is known without excavation of the site and surrounding region, Fisher said it was likely that European diseases had at least in part contributed to the culture’s disappearance.
The expedition also found and documented 52 artifacts that Virgilio Paredes, head of Honduras’s national anthropology and history institute, said indicated a civilisation distinct from the Mayans. Those artifacts included a bowl with an intricate carvings and semi-buried stone sculptures, including several that merged human and animal characteristics.
The cache of artifacts – “very beautiful, very fantastic,” in Fisher’s words – may have been a burial offering, he said, noting the effigies of spirit animals such as vultures and serpents.
Fisher said that while an archaeologist would likely not call these cities evidence of a lost civilisation, he would call it evidence of a culture or society. “Is it lost? Well, we don’t know anything about it,” he said.
The exploratory team did not have a permit to excavate and hopes to do so on a future expedition. “That’s the problem with archaeology is it takes a long time to get things done, another decade if we work intensively there, but then we’ll know a little more,” Fisher said.

“This wasn’t like some crazy colonial expedition of the last century,” he added.
Despite the abundance of monkeys, far too little is known of the site still to tie it to the “lost city of the monkey god” that one such expedition claimed to have discovered. In about 1940, the eccentric journalist Theodore Morde set off into the Honduran jungle in search of the legendary “white city” that Spanish conquistadors had heard tales of in the centuries before.
He broke out of the brush months later with hundreds of artifacts and extravagant stories of how ancient people worshipped their simian deity. According to Douglas Preston, the writer National Geographic sent along with its own expedition: “He refused to divulge the location out of fear, he said, that the site would be looted. He later committed suicide and his site – if it existed at all – was never identified.”
Fisher emphasised that archaeologists know extraordinarily little about the region’s ancient societies relative to the Maya civilisation, and that it would take more research and excavation. He said that although some academics might find it distasteful, expeditions financed through private means – in this case the film-makers Benenson and Elkins – would become increasingly commonplace as funding from universities and grants lessened.
Fisher also suggested that the Lidar infrared technology used to find the site would soon be as commonplace as radiocarbon dating: “People just have to get through this ‘gee-whiz’ phase and start thinking about what we can do with it.”
Paredes and Fisher also said that the pristine, densely-wooded site was dangerously close to land being deforested for beef farms that sell to fast-food chains. Global demand has driven Honduras’s beef industry, Fisher said, something that he found worrying.
“I keep thinking of those monkeys looking at me not having seen people before. To lose all this over a burger, it’s a really hard pill to swallow.”

Mysterious radio signal from space caught live for first time




Excerpt from foxnews.com

Astronomers in Australia have picked up an “alien” radio signal from space for the first time as it occurred. The signal, or radio “burst”, was discovered on May 15, 2014, though it’s just being reported by the Monthly Notices of the Royal Astronomical Society. “The burst was identified within 10 seconds of its occurrence,” said Emily Petroff, a doctoral student from Melbourne’s Swinburne University of Technology. “The importance of the discovery was recognized very quickly and we were all working very excitedly to contact other astronomers and telescopes around the world to look at the location of the burst.”
Emerging from an unknown source, these bursts are bright flashes of radio waves that emit as much energy in a few milliseconds as the sun does in 24 hours.  “The first fast radio burst was discovered in 2007,” Petroff tells FoxNews.com, “and up until our discovery there were 8 more found in old or archival data.” While researchers use telescopes in Hawaii, India, Germany, Chile, California, and the California Islands to search for bursts, it is the CSIRO Parkes radio telescope in Eastern Australia that is the first to catch one as its happening.
The cause of these mysterious signals remains unknown, with possible theories ranging from black holes to alien communication. However, UFO hunters shouldn’t get too excited. According to Petroff, “We're confident that they're coming from natural sources, that is to say it's probably not aliens, but we haven't solved the case completely. The two most promising theories at the moment are that these bursts could be produced either by a star producing a highly energetic flare, or from a neutron star collapsing to make a black hole. Both of these things would be from sources in far-away galaxies just reaching us from billions of light years away.”
Catching the bursts as they happen is key to finding the source, and though Petroff’s team scrambled upon making their discovery, they didn’t move fast enough to find the afterglow and pin down the cause. “Finding one in real-time has been the goal for a while because we would then be able to act on it and mobilize other telescopes to look that way,” Petroff says. “We did this in the case of this real-time discovery, but we didn't get on the target until about eight hours later with other telescopes, at which time nothing was found.” However, they were able to eliminate a few possible causes, such as gamma-ray bursts from exploding stars and supernovae. Also, the team was able to determine that the source had been near an object with a sizeable magnetic field from the way the wavelengths were polarized.
While the source of the fast radio burst remains a mystery, the team remains hopeful that they can learn from their mistakes and one day solve the case. “All we can do is learn from our experience with this discovery and create a more efficient system for next time,” Petroff says. “We still spend a large amount of time looking for fast radio bursts with the Parkes telescope and the next time we are in the right place at just the right time, we'll be able to act faster than ever before and hopefully solve the mystery once and for all!”

Theoretical physics: The origins of space and time


Excerpt from nature.com
By Zeeya Merali


Many researchers believe that physics will not be complete until it can explain not just the behaviour of space and time, but where these entities come from.

“Imagine waking up one day and realizing that you actually live inside a computer game,” says Mark Van Raamsdonk, describing what sounds like a pitch for a science-fiction film. But for Van Raamsdonk, a physicist at the University of British Columbia in Vancouver, Canada, this scenario is a way to think about reality. If it is true, he says, “everything around us — the whole three-dimensional physical world — is an illusion born from information encoded elsewhere, on a two-dimensional chip”. That would make our Universe, with its three spatial dimensions, a kind of hologram, projected from a substrate that exists only in lower dimensions.

This 'holographic principle' is strange even by the usual standards of theoretical physics. But Van Raamsdonk is one of a small band of researchers who think that the usual ideas are not yet strange enough. If nothing else, they say, neither of the two great pillars of modern physics — general relativity, which describes gravity as a curvature of space and time, and quantum mechanics, which governs the atomic realm — gives any account for the existence of space and time. Neither does string theory, which describes elementary threads of energy.

Free podcast

Zeeya Merali discusses some of the theories that are trying to explain the origins of space and time.


Van Raamsdonk and his colleagues are convinced that physics will not be complete until it can explain how space and time emerge from something more fundamental — a project that will require concepts at least as audacious as holography. They argue that such a radical reconceptualization of reality is the only way to explain what happens when the infinitely dense 'singularity' at the core of a black hole distorts the fabric of space-time beyond all recognition, or how researchers can unify atomic-level quantum theory and planet-level general relativity — a project that has resisted theorists' efforts for generations.

“All our experiences tell us we shouldn't have two dramatically different conceptions of reality — there must be one huge overarching theory,” says Abhay Ashtekar, a physicist at Pennsylvania State University in University Park.

Finding that one huge theory is a daunting challenge. Here, Nature explores some promising lines of attack — as well as some of the emerging ideas about how to test these concepts...

How will the world end? From ‘demonic’ AI to nuclear war — seven scenarios that could end human race




news.nationalpost.com 


Humanity may have already created its own nemesis, Professor Stephen Hawking warned last week. The Cambridge University physicist claimed that new developments in the field of artificial intelligence (AI) mean that within a few decades, computers thousands of times more powerful than in existence today may decide to usurp their creators and effectively end humanity’s 100,000-year dominance of Earth.
This Terminator scenario is taken seriously by many scientists and technologists. Before Prof. Hawking made his remarks, Elon Musk, the genius behind the Tesla electric car and PayPal, had stated that “with artificial intelligence, we are summoning the demon,” comparing it unfavourably with nuclear war as the most potent threat to humanity’s existence.
Aside from the rise of the machines, many potential threats have been identified to our species, our civilization, even our planet. To keep you awake at night, here are seven of the most plausible.

Getty Images / ThinkStockAn artist's depiction of an asteroid approaching Earth.
1. ASTEROID STRIKE
Our solar system is littered with billions of pieces of debris, from the size of large boulders to objects hundreds of kilometres across. We know that, from time to time, these hit the Earth. Sixty-five-million years ago, an object – possibly a comet a few times larger than the one on which the Philae probe landed last month – hit the Mexican coast and triggered a global winter that wiped out the dinosaurs. In 1908, a smaller object hit a remote part of Siberia and devastated hundreds of square kilometres of forest. Last week, 100 scientists, including Lord Rees of Ludlow, the Astronomer Royal, called for the creation of a global warning system to alert us if a killer rock is on the way.
Probability: remote in our lifetime, but one day we will be hit.
Result: there has been no strike big enough to wipe out all life on Earth – an “extinction-level event” – for at least three billion years. But a dino-killer would certainly be the end of our civilization and possibly our species.
Warner Bros.
Warner Bros.When artificial intelligence becomes self-aware, there is a chance it will look something like this scene from Terminator 3.
2. ARTIFICIAL INTELLIGENCE
Prof. Hawking is not worried about armies of autonomous drones taking over the world, but something more subtle – and more sinister. Some technologists believe that an event they call the Singularity is only a few decades away. This is a point at which the combined networked computing power of the world’s AI systems begins a massive, runaway increase in capability – an explosion in machine intelligence. By then, we will probably have handed over control to most of our vital systems, from food distribution networks to power plants, sewage and water treatment works, and the global banking system. The machines could bring us to our knees without a shot being fired. And we cannot simply pull the plug, because they control the power supplies.

Probability: unknown, although computing power is doubling every 18 months. We do not know if machines can be conscious or “want” to do anything, and sceptics point out that the cleverest computers in existence are currently no brighter than cockroaches.
Result: if the web wakes up and wants to sweep us aside, we may have a fight on our hands (perhaps even something similar to the man vs. machines battle in the Terminator films). But it is unlikely that the machines will want to destroy the planet – they “live” here, too.

3. A GENETICALLY CREATED PLAGUE
This is possibly the most terrifying short-term threat because it is so plausible. The reason Ebola has not become a worldwide plague – and will not do so – is because it is so hard to transmit, and because it incapacitates and kills its victims so quickly. However, a modified version of the disease that can be transmitted through the air, or which allows its host to travel around for weeks, symptom-free, could kill many millions. It is unknown whether any terror group has the knowledge or facilities to do something like this, but it is chilling to realize that the main reason we understand Ebola so well is that its potential to be weaponized was quickly realized by defence experts.
Probability: someone will probably try it one day.
Result: potentially catastrophic. “Ordinary” infectious diseases such as avian-flu strains have the capability to wipe out hundreds of millions of people.

4. NUCLEAR WAR
This is still the most plausible “doomsday” scenario. Despite arms-limitations treaties, there are more than 15,000 nuclear warheads and bombs in existence – many more, in theory, than would be required to kill every human on Earth. Even a small nuclear war has the potential to cause widespread devastation. In 2011, a study by NASA scientists concluded that a limited atomic war between India and Pakistan involving just 100 Hiroshima-sized detonations would throw enough dust into the air to cause temperatures to drop more than 1.2C globally for a decade.
Probability: high. Nine states have nuclear weapons, and more want to join the club. The nuclear wannabes are not paragons of democracy.
Result: it is unlikely that even a global nuclear war between Russia and NATO would wipe us all out, but it would kill billions and wreck the world economy for a century. A regional war, we now know, could have effects far beyond the borders of the conflict.

CERN)/MCTThis is one of the huge particle detectors in the Large Hadron Collider, a 17 mile-long tunnel under the French-Swiss border. Scientists are searching for evidence of what happened right after- and perhaps before- the Big Bang.
5. PARTICLE ACCELERATOR DISASTER
Before the Large Hadron Collider (LHC), the massive machine at CERN in Switzerland that detected the Higgs boson a couple of years ago, was switched on, there was a legal challenge from a German scientist called Otto Rossler, who claimed the atom-smasher could theoretically create a small black hole by mistake – which would then go on to eat the Earth.
The claim was absurd: the collisions in the LHC are far less energetic than those caused naturally by cosmic rays hitting the planet. But it is possible that, one day, a souped-up version of the LHC could create something that destroys the Earth – or even the universe – at the speed of light.
Probability: very low indeed.
Result: potentially devastating, but don’t bother cancelling the house insurance just yet.

6. ‘GOD’ REACHES FOR THE OFF-SWITCH
Many scientists have pointed out that there is something fishy about our universe. The physical constants – the numbers governing the fundamental forces and masses of nature – seem fine-tuned to allow life of some form to exist. The great physicist Sir Fred Hoyle once wondered if the universe might be a “put-up job”.
More recently, the Oxford University philosopher Nick Bostrom has speculated that our universe may be one of countless “simulations” running in some alien computer, much like a computer game. If so, we have to hope that the beings behind our fake universe are benign – and do not reach for the off-button should we start misbehaving.
Probability: according to Professor Bostrom’s calculations, if certain assumptions are made, there is a greater than 50% chance that our universe is not real. And the increasingly puzzling absence of any evidence of alien life may be indirect evidence that the universe is not what it seems.
Result: catastrophic, if the gamers turn against us. The only consolation is the knowledge that there is absolutely nothing we can do about it.

7. CLIMATE CATASTROPHE
Almost no serious scientists now doubt that human carbon emissions are having an effect on the planet’s climate. The latest report by the Intergovernmental Panel on Climate Change suggested that containing temperature rises to below 2C above the pre-industrial average is now unlikely, and that we face a future three or four degrees warmer than today.
This will not literally be the end of the world – but humanity will need all the resources at its disposal to cope with such a dramatic shift. Unfortunately, the effects of climate change will really start to kick in just at the point when the human population is expected to peak – at about nine billion by the middle of this century. Millions of people, mostly poor, face losing their homes to sea-level rises (by up to a metre or more by 2100) and shifting weather patterns may disrupt agriculture dramatically.
Probability: it is now almost certain that CO2 levels will keep rising to 600 parts per billion and beyond. It is equally certain that the climate will respond accordingly.
Result: catastrophic in some places, less so in others (including northern Europe, where temperature rises will be moderated by the Atlantic). The good news is that, unlike with most of the disasters here, we have a chance to do something about climate change now.
