The next three sequences show the evolution of the Earth's surface in reverse, from the present day to, at the very bottom, 600 million years ago, when nearly all of the planet's landmasses were joined together in the Antarctic. The first sequence shows roughly 90 million years of backward evolution, the continents pulling apart from one another and beginning a slow drift south. They were mapped using the Mollweide projection, and, in all cases, are by Ron Blakey.

5 Unconventional Maps to Get Lost In
Posted by: Aaron Weyenberg.
From the earliest days of human exploration we’ve made progressively more accurate and sophisticated maps. Maps help us find our way around the world we live in. Maps help us get to our destination. Maps keep us from becoming lost.
But what if you have no destination? What if becoming lost is the point? Well, there’s a map for that. Lots of them, actually.
See the TEDTalk: Eric Berlow and Sean Gourley: Mapping ideas worth spreading
Unconventional maps are on the mind today because today’s talk features one. TED Fellows Eric Berlow and Sean Gourley share how they created a map of the TEDx Universe – which looks a bit like an everlasting gobstopper — out of the diverse ideas expressed at TEDx events. The pair got the idea to create this map upon discovering that they had both spoken at TED conferences. They decided to use the YouTube transcripts of 24,000 TEDx talks to pinpoint the connections that exist between them. From there, they mapped the mathematical structure that underlies these ideas. Hear more about how they created this map, and how incredible it is to lose yourself in it, by watching the talk.
Here are four other maps you can thoroughly lose yourself in.
The Atlas of True Names. Have you ever heard of the Mountain by the Noisy Lake? Or traveled through the Land of the Palefaces? Or visited the town of Sibling Love? The Atlas of True Names reveals the etymological origins of the names for places we see on today’s maps.
Bob Dylan’s World. Every place mentioned in every Bob Dylan song, mapped. Each pinned location contains a corresponding lyric, song and album — and is guaranteed to get a song running through your head.
Countries invaded by the British. Sir Ken Robinson, in his talk at our TED Talks Education PBS special, joked that the British have invaded every country they’ve ever visited. Was he exaggerating? This map suggests not so much.
Geoguessr. Part map and all game, Geoguessr drops you somewhere on the planet in Google Maps street view. Your task is to figure out where in the world you are. Gather clues from things like signage, the lay of the land, architecture, vegetation or which side of the road vehicles travel on. You can even challenge your friends.

Seismologists Puzzle Over Largest Deep Earthquake Ever Recorded
Repost from Science Daily, September 19, 2013
A magnitude 8.3 earthquake that struck deep beneath the Sea of Okhotsk on May 24, 2013, has left seismologists struggling to explain how it happened. At a depth of about 609 kilometres (378 miles), the intense pressure on the fault should inhibit the kind of rupture that took place.
The May 24, 2013 Mw 8.3 earthquake beneath the Sea of Okhotsk,
Russia, occurred as a result of normal faulting at a depth of approximately 600
km (portion of USGS poster).
Lay is co-author of a paper, published in the September 20 issue of Science, analyzing the seismic waves from the Sea of Okhotsk earthquake. First author Lingling Ye, a graduate student working with Lay at UC Santa Cruz, led the seismic analysis, which revealed that this was the largest deep earthquake ever recorded, with a seismic moment 30 percent larger than that of the next largest, a 1994 earthquake 637 kilometres beneath Bolivia.
Deep earthquakes occur in the transition zone between the upper mantle and lower mantle, from 400 to 700 kilometres below the surface. They result from stress in a deep subducted slab where one plate of Earth's crust dives beneath another plate. Such deep earthquakes usually don't cause enough shaking on the surface to be hazardous, but scientifically they are of great interest.
The energy released by the Sea of Okhotsk earthquake produced vibrations recorded by several thousand seismic stations around the world. Ye, Lay, and their co-authors determined that it released three times as much energy as the 1994 Bolivia earthquake, comparable to a 35 megaton TNT explosion. The rupture area and rupture velocity were also much larger. The rupture extended about 180 kilometres, by far the longest rupture for any deep earthquake recorded, Lay said. It involved shear faulting with a fast rupture velocity of about 4 kilometres per second (about 9,000 miles per hour), more like a conventional earthquake near the surface than other deep earthquakes. The fault slipped as much as 10 meters, with average slip of about 2 meters.
"It looks very similar to a shallow event, whereas the Bolivia earthquake ruptured very slowly and appears to have involved a different type of faulting, with deformation rather than rapid breaking and slippage of the rock," Lay said.
The researchers attributed the dramatic differences between these two deep earthquakes to differences in the age and temperature of the subducted slab. The subducted Pacific plate beneath the Sea of Okhotsk (located between the Kamchatka Peninsula and the Russian mainland) is a lot colder than the subducted slab where the 1994 Bolivia earthquake occurred.
"In the Bolivia event, the warmer slab resulted in a more ductile process with more deformation of the rock," Lay said.
The Sea of Okhotsk earthquake may have involved re-rupture of a fault in the plate produced when the oceanic plate bent down into the Kuril-Kamchatka subduction zone as it began to sink. But the precise mechanism for initiating shear fracture under huge confining pressure remains unclear. The presence of fluid can lubricate the fault, but all of the fluids should have been squeezed out of the slab before it reached that depth.
"If the fault slips just a little, the friction could melt the rock and that could provide the fluid, so you would get a runaway thermal effect. But you still have to get it to start sliding," Lay said. "Some transformation of mineral forms might give the initial kick, but we can't directly detect that. We can only say that it looks a lot like a shallow event."

This is Your Brain on Maps
I love this one! See BigThink. By Frank Jacobs. Posted: September 18, 2013, 7:45 PM
If you think that trawling the internet for cartography is a
harmless endeavour, you are sorely mistaken. Think again. If you still can, that
is.
The relentless perusal of maps - one more, and then another, but
never the last one - is a perversion of the normal requirement in healthy
individuals for spatial positioning.
Instead of going outside, taking in the fresh air of the real world,
and interacting with the length and breadth of an actual landscape,
so-called map-heads stay indoors, wedging themselves in stuffy rooms,
to scan atlases for lurid cartography, or flick through websites for fringe
maps, all to satisfy their marginal urges!
This perversion has dire consequences for one's physical and
spiritual health.
How sad! Here be monsters indeed. For these sins against normality
are not without punishment. Horrible cranial disfigurement is one possible
consequence of sustained cartophilia - usually commensurate with the type of
cartographical projection preferred by the patient.
If he or she (but let's face it, usually a he) is lucky,
that projection is the globular one. The subject's head is nearly normal, and
only slightly pinched at the front and back of the skull. Occasionally, when the
subject ventures out to buy another atlas, there will be shouts on the street
like: Hey! Aren't you Austin Powers' dad? Being a map-head, the subject
is used to a lot worse abuse than that.
But it takes only a slight predilection for orthographic
maps to end up with a pinhead like the one in the upper right corner of
this image. Not only does this lead to a dramatic contraction of the cranial
area, plus a severe reduction in mental facilities, it also doubles the ears in
size, leaving the brain with much more audio input than it can process.
It could be argued that the deformation caused by the stereographic
deviancy (lower left corner) is the lesser of the four evils; except that it
makes you look like Bashar al-Assad's twin brother. Which is not an ideal mug to
have to carry around these days, either inside or outside Syria.
Perhaps the lesser of all evils is the Mercatorhead, shown bottom
right. Yes, the inflated chin and ballooning skull will frighten children, and
perhaps even put some pets to flight. But a this will provide the patient with a
lot more alone-time, and consequently with a lot more opportunity to fill that
big old head with a lot more maps.
However, a vicious circle of Mercatorial map-consumption and cranial
growth will eventually cause the subject to outgrow his stuffy room, but too big
to leave through the door or window. The consequences are nasty, and usually
require expensive redecoration of said room.
So help us stop map abuse! If you know someone neglecting normal
outdoor activities in order to indulge in cartography, have the courage to break
the chain of addiction. Tell them: Life is more than maps! Real life is better
than maps!

Is Canada's Northwest Passage the next Everest?
Northwest Passage a new magnet for marine adventurers,
following more treacherous routes in smaller vessels. The Coast Guard fears more
accidents.
VANCOUVER—For sailors drawn to the edge, the seas of
Canada’s Northwest Passage pull like no other waters can.
The fabled Arctic voyage grabbed hold of Philipp Cottier’s imagination when
he was a boy in Switzerland reading the logs of legendary explorers such as Sir
John Franklin and Roald Amundsen.
It never let go.
As the climate warmed, and vast stretches of sea ice melted this summer,
Cottier, 46, joined a growing number of yachtsmen trying to conquer a passage
that has killed hundreds who sailed before them.
The Swiss hedge fund investor and philanthropist consulted naval engineers
and toughened up the fibreglass hull of Libellule, a 14-metre catamaran, to give
her a fighting chance against the Arctic.
He added Kevlar to the bows and sides, and reinforced the rudder
shafts.
Then, in mid-July, Cottier, his wife Marielle and their three daughters,
Naima, 14, Line, 12, and Anissa, 8, cast off for the Canadian Arctic by way of
Nuuk, Greenland.
With two experienced French skippers to take the wheel, they set sail for
history, determined to make Libellulethe first cruising catamaran to
navigate the Northwest Passage, which joins the Atlantic to the Pacific across
the top of the world.
Weeks later, Cottier is almost there. A lifelong dream is now riding on a
hard Arctic reality: ice.
It’s back with a vengeance after retreating to record lows in recent years,
almost disappearing completely over the past two summers.
Cottier and his crew are among dozens of mariners scattered across the
Northwest Passage, searching for some way out as hull-crushing ice clogs up the
exits and a bitter winter closes in.
“Life is too short to live it in a boring way,” he emails from aboard
Libellule, heading northwest of Cambridge Bay, on Victoria Island.
“I prefer to live a full life, including some adventures from time to time
(such as mountaineering or sailing expeditions). And, fortunately, I have a
family who is willing to share some of these adventures.”
Word that the Arctic has been warming faster than anywhere else on the planet
— and images of calm, ice-free waters, even of sunbathers on deck — has made the
Northwest Passage a new magnet for marine adventurers.
Luxury cruise ships full of tourists are almost as common as polar bears in
Canada’s Arctic. So being in the Northwest Passage is losing the buzz it had
when only grizzled explorers dared venture. The race now is to transit by the
most treacherous routes or in the smallest craft afloat.
At least three rowboats and a tandem kayak launched attempts this year. And a
team of four Americans on jet skis set out on a voyage through the passage in
search of reality TV glory.
Douglas Pohl, an American sea captain who keeps a close watch on traffic in
the Northwest Passage after some 30 years navigating the world’s oceans, calls
paddling rowers insane for launching such attempts.
“It serves no real purpose and places people at extreme risk,” he says from
his 16.7-metre steel motor yacht Grey Goose, where he is cruising, and blogging
about the Northwest Passage, among the Caribbean islands of Bocas del Toro
Panama.
Mount Everest, another destination once reserved for major expeditions, is
now inundated with climbers, many with more money than alpine experience. Fatal
accidents keep rising with the crowds.
Canada’s overstretched Coast Guard fears the same will happen in the
Northwest Passage, where the agency says emergency rescues are still rare
despite a steady increase in inexperienced, poorly prepared boaters.
“So far, we’ve been lucky that we haven’t really had any major incidents
involving any of those type of navigators or vessels to date,” says Jean-Pierre
Sharp, regional supervisor, maritime search and rescue, from his base in
Trenton, Ont.
Pohl says he tried to talk the rowboaters out of making the trip. Two have
abandoned their attempts in recent days after only making it about half
way.
The final rowboat and the tandem kayak won’t last much longer, Pohl
predicts.
Since 2010, Ottawa has required all Arctic-bound ships over 300 tonnes, or
carrying dangerous goods, to register. That remains voluntary for smaller
vessels, which make up the majority of traffic through the Northwest
Passage.
Although Canada claims the route as territorial waters, it doesn’t require
vessels to get permission to enter the way Russia does in the much busier waters
along its Arctic coast.
So even though Prime Minister Stephen Harper declares Arctic sovereignty one
of his top priorities, the Coast Guard can only estimate how many vessels are
passing through.
It knows even less about who is on board or what they are up to. Harper
closed the only Coast Guard station in the western Arctic last year.
Shifts of three Coast Guard staff in Iqaluit are left to monitor sea traffic,
and field calls for weather and hazard information, across Canada’s vast
north.
They keep watch over a dangerous wilderness from Greenland west to Alaska,
from the northern tip of Ellesmere Island south to James Bay, and along the busy
Mackenzie River.
Some of their information comes from listening to radios, or monitoring GPS
satellite locations. They also search the Internet for clues about vessels that
haven’t declared their intentions.
If you run into trouble in the Northwest Passage and radio “Mayday,” and the
Coast Guard can’t raise another ship nearby, you’ll likely have a long wait for
help. Rescue operations in Canada’s Arctic are run out of Trenton, 170
kilometres east of Toronto.
The Coast Guard doesn’t have the authority to tell boaters to stay out — even
if they look like they’d be in over their heads in Arctic waters.
“We just hope, and try to tell them to be prepared,” says Sharp. “Hopefully,
they may have groups with them, or monitoring them, or have a good support team
in that sense.
“But we really can’t persuade people not to go. The Coast Guard has no ‘legal
side’ to us, if you will. It’s not just the North. I can’t refuse people from
venturing out on the Great Lakes or anything else.”
By late August, the Coast Guard knew of 24 vessels either in the Northwest
Passage or planning to go there, and only three of those were large ships
required to file notice, says Iqaluit spokesman Louis Robert.
Pohl has counted around 35 vessels in the passage this season, several of
which contacted him for free guidance.
Russia is much more strict in regulating its Arctic sea passages, called the
Northern Sea Route. At least 270 ships, mostly large commercial vessels,
received permits to sail at least part of the way between Asia and Europe this
year.
All vessels must apply for a permit to transit the Russian route. Getting one
requires, among other things, proof of experience navigating in sea ice,
adequate preparations and insurance.
Russia also charges Arctic mariners hefty fees to pay for mandatory
icebreaker escorts.
Canada’s much smaller fleet of Coast Guard icebreakers only help vessels in
the Northwest Passage if a call for help goes out.
The Canadian Coast Guard icebreaker CCGS Sir Wilfrid Laurier had to rescue
the American jet skiers and drop them off at Gjoa Haven, the only settlement on
King William Island.
Rachelle Smith, a spokesperson for the department of fisheries and oceans,
declined to say specifically whether the jet skiers or the producers of the
Dangerous Waters TV show have to pay for the costly rescue.
Coast Guard “operations are funded on a yearly/seasonal basis not on a
service basis,” she says in an email. “Therefore, the department does not
calculate cost estimates or assess cost recovery for individual search and
rescue cases.”
To Pohl, it’s obvious the jet skiers, and small self-propelled craft like
rowboats, shouldn’t be trying to voyage across the Arctic in the first
place.
“I knew it was sheer madness from the start and it has got to be
gut-wrenching to know that Mother Nature once again showed her power and kicked
their butts,” Pohl says. “Their failure was their poor preparation for the
legendary Arctic ice and weather. They just didn’t do their homework.”
By the end of last year, 185 vessels had navigated the Northwest Passage
since 1903, when Norwegian explorer Roald Amundsen was the first to sail through
aboard Gjoa, according to Robert Headland, a polar historian at Cambridge
University.
Amundsen and his crew took three years to succeed.
By far the majority of the voyages through the passage — 109 of them — have
been completed since 2000. Most of those vessels were sailboats or motor yachts,
Headland’s research shows.
The Northwest Passage is made up of seven possible routes, and ice
choke-points have blocked several of the main ones this summer, Pohl
says.
That “puts extreme pressure on vessel skippers to make a decision — to wait
or to attempt to find a way through the ice,” Pohl adds. “Good decisions are
never made under duress — you only get one chance in the Arctic.
“A poor decision usually means someone is going to suffer. Ice pressure
against a ship’s hull usually means you lose and Mother Nature wins — imagine
the forces from thousands of tons of ice being moved by winds coming to rest
against a ship’s hull.”
As ice closes in, skippers close enough to a hamlet that is equipped to haul
them out can surrender, put the boat on blocks so she stays in one piece, and be
ready to try again next summer. Mariners call it “going on the hard.”
But the facilities to do that are few and far between in the Canadian
Arctic.
And mariners who want bragging rights for transiting the Northwest Passage
crave the phrase “in a single season.” Winter breaks don’t have quite the same
cache.
“I think Roald Amundsen had sage advise: ‘Adventure is just bad planning,’”
Pohl says.
Even in a good year, the Arctic’s patience for mariners is short and the
window for transiting the Northwest Passage shuts fast.
Pohl has some advice for the seamen still there: “Get out of the Arctic
before Sept. 15 or else make plans to winter over near a hamlet with
services.”
Despite the risks, Cottier has had enough magic moments, such as watching his daughters’ eyes light up as they floated past polar bears on an ice floe, and met enough friendly people on his voyage to ask: “What can you wish more?”
Despite the risks, Cottier has had enough magic moments, such as watching his daughters’ eyes light up as they floated past polar bears on an ice floe, and met enough friendly people on his voyage to ask: “What can you wish more?”
But it’s easy to be romantic about the Arctic, until her icy breath hits you
in the face in a howling gale.
Cottier felt it on Sept. 1 when winds gusting to 45 knots dragged Libellule
on her anchor for some 200 metres. With snow blowing horizontally, two-metre
waves hammered the boat while shoals and rocks waited to tear a hole in the
hull.
But the storm passed and she sailed on.
So far, ice has been the biggest headache and the most stunning sight.
Judging from Amundsen’s account of his voyage, Cottier thinks he’s come up
against more of it than the Norwegian did in 1903.
“Generally, being in the ice is very, very beautiful, but very extreme at the
same time because you never know how to get out,” Cottier says. “It is very
scary.
“As our youngest daughter nicely summarized it, being in the pack ice is
‘like a labyrinth, except that it is for real, and the labyrinth is constantly
changing, and you don’t even know if there is an exit!’”
That held up Libellule so long that Cottier’s wife and daughters had to go
ashore at Cambridge Bay.
It was time for the girls to fly back to school, leaving their father and crew to see what was stronger, a boyhood dream or the ice.

Cottier completed his transit of the Northwest Passage Tuesday, when Libellule
crossed the Arctic Circle in the morning and then headed into the Bering Strait
that evening.
“The sun was shining, for the first time since Herschel Island, Canada, and
we could clearly see Siberia on our starboard side and Alaska on our port side,”
the triumphant yachtsman writes.
He and his crew celebrated with the last beer on board and a bottle of rum as
they set sail for port in Nome, Alaska.
“Life is beautiful . . .”
“We have just spotted a walrus colony on nearby Fairway Rock,” Cottier says,
signing off on a 7,500-kilometre voyage “across the Arctic waters and ice of
Greenland, Canada and Alaska.”

In India, bottled water may not offer protection from Delhi belly
In India, bottled water may not offer protection from Delhi belly
It’s been a forgettable year for India tourism.
When foreign
media aren’t reporting on gamg rapes and sexual assaults in the country of 1.2
billion, journalists are documenting the freefalling Indian economy.
Now for some
more sour news for every visitor to sprawling India who carefully avoids ice in
their drinks, believing that avoiding tap water will help them avoid awkward
cases of travelers diarrhea: bottled water may not help prevent Delhi belly.
According to
a report in The Times of India,
as much as 20 per cent of bottled water tested in New Delhi during 2010-11 and
2011-12 failed quality testing. The results were revealed last week by consumer
affairs minister K V Thomas in a written reply to a question posed in Indian
parliament, Lok Sabha.
At least 23
of 190 samples in the national capital region failed and the licences of two
bottled water companies were revoked.
Bacteria-laden
bottled water might sound familiar. In the Academy Award-winning movie Slumdog
Millionaire, one of the young characters lands a job at a restaurant, filling
water bottles up with tap water, and then using a glue to fix the top it in
place and making it seem like a new bottle.
“I have also
seen young boys filing up 25 litre Bisleri and Kinley bottles from the roadside
taps,” notes one Times of India reader.
So what's a
tourist to do?
The Website Matadornetwork.com offers a few pointers that may
help avoid a bad stomach bug. Its best advice: avoid fish you don't see caught
and cooked; avoid eggs and cheese; and wash your hands regularly.

How fracking caused 109 earthquakes in Ohio town
Caption: Anti-fracking protestors
demonstrate at the state legislature in Albany, New York, in this photo.
The recent surge in U.S. oil and gas production has been linked to an increase in
small to moderate induced earthquakes in Oklahoma, Arkansas, Ohio, Texas and
Colorado. (Reuters photo.)
For over a century, there were no
earthquakes in Youngstown, Ohio. In fact, there were no recorded seismic events
in the town since observations began in 1776. But between December 2010 and
December 2011, Youngstown recorded 109 earthquakes.
So what gives?
Fracking. So say authors of
research published in the journal Geophysical Research Letters.
Fracking involves injecting
millions of litres of water and thousands of litres of chemicals underground at
very high pressure to create fractures in shale rock formations to extract
previously inaccessible natural gas. An average well takes four million to
eight million gallons of water to drill in and frack. There can be up to 20
wells on a single pad that is spread over an acre.
It is considered a boon because
it has opened a hidden treasure trove; it has also divided communities, created fears about health.
In December 2010, Northstar 1, a
well built to pump wastewater produced by fracking in the neighbouring state of
Pennsylvania, came online. In the next 12 months, Youngstown recorded 109
earthquakes; the strongest was a magnitude 3.9 quake on Dec. 31, 2011.
The authors of the study analyzed
the earthquakes and found that their onset, cessation, and temporary dips were
tied to activities at the Northstar 1 well. The first earthquake recorded in
the city occurred 13 days after pumping began; the tremors stopped soon after
the Ohio Department of Natural Resources shut down the well in December 2011.
Won-Young Kim, a seismologist at
Columbia University and one of the authors of the study, said the earthquakes
in Youngstown were directly caused by the pressure buildup and stopped when
pressure dropped.
The earthquakes, according to the
paper, were apparently centered in an ancient fault near the Northstar 1 well,
and pressure from wastewater injection caused this fault to rupture.
However, of the 177 wastewater
disposal wells of this size active in Ohio during 2011, only the Northstar 1
well was linked with this kind of seismic activity, suggesting this ability to
cause earthquakes was rare.

Some Good News: "90 million child deaths prevented since 1990, UNICEF says"
Jennifer Yang, Global Health reporter for the Toronto Star. Thursday September 12, 2013.
Innovations in health care delivery and political commitment
credited for improved child survival.
Nearly half as many children under 5 are dying today compared to two decades ago, with 90 million deaths prevented since 1990, according to new estimates published by UNICEF and other international agencies.“I think we’re seeing a child survival revolution going on,” said David Morley, president and CEO of UNICEF Canada. “Fewer children are dying today than ever before in human history.”
These latest figures were
published in two new reports, jointly released on Thursday by UNICEF, the World
Health Organization, the World Bank and the UN Inter-agency Group for Child
Mortality Estimation.
They estimate that in 2012, 6.6 million children died before the
age of 5, or 18,000 deaths per day. While these numbers are still unacceptably
high, they are a huge improvement from 1990, when 12.6 million children died
before celebrating their fifth birthdays.
What’s changed over the last two decades? Chalk it up to cheaper
and better treatments, innovations in health care delivery and sustained
political commitment toward improving child survival, UNICEF deputy executive
director Geeta Rao Gupta said in a telephone news conference.
Gupta noted that some of the world’s poorest countries have also
defied expectations by making the biggest strides in improving child survival.
Bangladesh, Nepal and Malawi, for example, have slashed their under-5 mortality
rates by two-thirds or more since 1990 — thus achieving one of the Millennium
Development Goals, a set of eight international targets established in 2000.
Despite the progress, there is an urgent need for more to be done,
Gupta said. Only two regions (East Asia and Pacific and Latin America and the
Caribbean) are on track to meeting the same millennium goal by the 2015
deadline.
Pneumonia and diarrhea continue to be the top killers of young
children, collectively accounting for more than 4,600 deaths every day in 2012,
according to the report.
“These statistics are all the more outrageous because so many of
these deaths . . . are preventable,” Gupta said.
The first month of life is also the most dangerous and nearly 44
per cent of under-5 deaths now occur during the first 28 days. Last year, 2.9
million newborns died within a month of being born, according to the new
estimates; roughly one million died on their very first day.
As survival rates continue to improve globally, 81 per cent of
under-5 deaths are now concentrated in two regions: South Asia (which has
actually seen the biggest reduction of under-5 deaths since 1990) and
sub-Saharan Africa, which together account for four out of every five deaths
under 5.
Sub-Saharan Africa has the world’s highest child mortality rates,
with 98 deaths for every 1,000 babies born. (Canada, by comparison, has a rate
of five deaths per 1,000 live births.) But even greater challenges loom:
despite making the least progress, the region will have the world’s largest
population of under-5 children by 2050.
Leading global health expert Dr. Zulfiqar Bhutta, the new
co-director of Sick Kids’ Global Child Health centre, welcomes these updated
estimates on child mortality.
He cautions, however, that they are largely based on projections.
As the UNICEF report itself points out, less than 3 per cent of causes for
under-5 deaths are medically certified and only 60 countries have registration
systems for tracking data on child deaths.
Bhutta said he would like to see whether these new estimates are
corroborated by two other groups expected to release child mortality estimates
in early 2014.

One of my former students who is now teaching geography asked me to recommend a couple of resources I use for teaching geography - particularly the "Canadian and World Issues" course.
I would highly recommend the the following as my current 'Top Three."
Stratfor provides a detailed and insightful analysis of world affairs, and tends to be ahead of conventional media sources. The information is relatively bias and agenda free. For geographers, it is one of the few sources that actually makes specific reference to location, space and place in explaining current geopolitical events. Stratfor covers a broad range of topics - from economics, to politics, to human rights - that fit beautifully with any course in World Issues. A subscription allows not only access to the full-range of products on their website, but also entitles the user to customizable e-mail updates. I find the "sit-rep" e-mails particularly useful as they provide "real time" updates on breaking news.
The Economist specializes in information on international business and world affairs. Headquartered in London, UK, with offices around the world, the Economist provides a much more "European" take on issues - a refreshing alternative to many of the traditional sources that tend to be more "American-centric." I subscribe to the print version, but web access comes with the subscription. The web content is very user friendly and provides additional information that helps to flesh out many of the issues explored in this weekly publication. While some may be deterred by the cost - $165.00 per year - it is well worth the investment. Division of the magazine into sections by geographic region allows you to get to the areas of specific interest quickly, and the articles themselves are well-written and provide detailed analysis of the issues. The one drawback for some is the heavy emphasis on economics/business stories.
Still one of the best sources for everything Canadian! Good value for the cost, and a must if you are teaching Canadian geography or social sciences. The articles are well-written and the photographs stunning. Reading level is appropriate for a wide range of ages. If I have one criticism, it is that the magazine has drifted from its geographic mandate, and has of late been far too historical in its focus.

Geo.me - Choropleth Mapping of World Bank Data
Geo.me has developed a series of choropleth maps using recently released World Bank data. It uses more than 1,000 data indicators between the years 1960 and 2008, and renders them on an interactive map.
To get going, select a year and click on one of the data topics listed below. A second table showing the individual data indicators available under that topic will then appear. Click on the required topic and an interactive map will be generated via a call to the World Bank API.
Check it out at: Geo.me World Bank Data
