Summary

From food shortages to global weather changes, there are ways to mitigate the risks of climate change, experts say. A new multi-national report outlines what we can expect as the planet continues to change with regard to climate patterns, and offers recommendations that focus on strategies from adaptation to mitigation.

The Intergovernmental Panel on Climate Change (IPCC) has approved the second part of its Fifth Assessment Report (AR5), titled Climate Change 2014: Impacts, Adaptation, and Vulnerability, at the IPCC meeting in Yokohama, Japan. The key message of the report is that climate change poses serious risks to the well-being of nature and people all over the world. The observed effects of climate change have an impact on people's health, land and marine ecosystems, water supplies, and people's livelihoods, from the polar regions to the tropics and from small islands to continents. Poor countries that lack the means to adapt to these changes will suffer the worst. 

"Despite our efforts, global greenhouse gas emissions continue to increase and the climate will change. We must strengthen Finland's ability to manage the risks related to climate change and adapt to it," emphasises Permanent Secretary Jaana Husu-Kallio from the Ministry of Agriculture and Forestry.

Professor Tim Carter from the Finnish Environment Institute (SYKE) is one of the lead writers of the now published report. He hopes that decision-makers will take the information produced by researchers seriously: "If adequate measures to reduce emissions are not taken, the fear is that some of the changes resulting from climate change will push us over an edge after which development can no longer be reversed. This kind of threshold could be, for example, the irreversible melting of Greenland's glaciers."

Europe's glaciers dwindling and permafrost melting

"Climate change impacts Europe in many ways. The ice sheets of the Alps and other mountain ranges are dwindling and an increasing portion of the permafrost is melting. In the northern coniferous forest belt, including Finland, the growth of forests is accelerating, and some species are growing more abundant, while others decline. The risk of forest fires is also increasing in southern Europe," Tim Carter explains about the regional effects of climate change.

In Finland, the effects of climate change may weaken the water quality of water systems, as the ground remains unfrozen for longer periods of time in the autumn and winter. Water protection efforts will have to adapt to increased run-off, erosion, and nutrition loads. This will result in new challenges, particularly in agricultural water protection. The warming of Finland's climate is already evident in Finnish fauna; birds, for example, are migrating earlier in the spring and later in the autumn.

Food shortages expected

The estimated future crop yields will not be enough to feed the world in 2015. "The climate has already changed and affected crop yields. The effects observed have been local, and for the most part negative. The most notable effects have had to do with extreme weather events, such as heavy rains, heat waves, and draught."

"Crop yields and food production per capita have generally improved over the last 40 years, due to the development of farming culture and technology, which has resulted in better fertilisers, better crop strains and more efficient production. However, climate change will result in more extreme weather, draught, heat, and heavy rains. In northern areas, global warming will initially also present benefits, such as longer growth periods," says Senior Researcher Kaija Hakala from MTT Agrifood Research Finland.

Severe and wide-ranging global changes

Warming, acidification, and decreasing oxygen levels will change marine life. Warming has already resulted in plankton, fish, and invertebrate communities shifting northwards. In northern marine areas, the diversity and biomass of fish populations have increased. Water warming has also altered the distribution of large species of fish found in the open sea. As marine and coastal ecosystems change, their diversity and the products and services derived from them will weaken. Those who depend on coastal areas for their livelihoods, such as fishing communities in the tropics and arctic areas, will suffer.

Rising sea levels, coastal flooding and tidal waves cause danger to life and risk of injury, and hinder livelihoods in low-lying coastal areas and in small island nations. These problems will impact poor population groups in particular. In some areas, flooding will also pose problems to urban populations.

Agricultural trade will grow more difficult and earnings from it will decrease due to the insufficient availability of drinking and irrigation water and the decreasing productivity of farming. These problems will have a particularly severe impact on poor farmers in dry regions.

Extreme weather events will hinder important basic services, such as water, electricity and health and rescue services. Mortality, morbidity and other adverse effects will increase during heat waves, particularly among vulnerable urban population groups and those who work outdoors.

Adaptation required in addition to mitigation

Countries all over the world have begun to develop climate change adaptation plans and strategies. Finland has been a pioneer in this regard, and Finland's reformed adaptation strategy is currently being widely circulated for comments. In Europe, the EU's adaptations strategy has led to adaptation planning being incorporated into, for example, the use and management of coastal areas and water systems and the risk management of natural disasters.

"Currently we are adapting mainly to past events when we should be adapting to future threats. However, it is good that governments, companies and communities are gaining experience in adaptation, since this experience can be utilised to better help society, and more ambitiously adapt to changes," says Chris Field, the Co-chair of IPCC Working Group II.

IPCC gathers information to support decision-making

The IPCC's Fifth Assessment Report consists of the now published report along with a report on the state of climate, which was published last September in Stockholm, and a report on climate change mitigation, which will be finalised at a meeting in Berlin from 7 to 11 April. A summary of the individual reports will be completed in autumn 2014.

The Intergovernmental Panel on Climate Change was called together by the World Meteorological Organization WMO and the UN's environmental programme UNEP. The goal of the panel is to support decision-making related to climate policy. Its tasks include assessing scientific knowledge related to climate change and its effects, as well as various climate change mitigation measures. During 2010-2013, some 813 writers took part in drawing up the report, five of them from Finland.

Dumb and Dumber, Thanks to GPS

 

“People should re-engage with their environment,” says Holly Taylor

Wednesday, April 9th 2014

By Helene Ragovin

Summary: What do a commuter taking a detour on the way to work and a youngster fashioning a bird out of a sheet of brightly colored paper have in common? They’re both depending on spatial cognition to complete a task. The trouble is that some of our beloved electronic devices could be a detriment to spatial cognition. Tufts University psychologist Holly Taylor and her colleagues study spatial cognition and comprehension. They tackle the effect of navigational aids on memory and whether learning the Japanese paper art origami can increase children’s abilities in all sorts of practical fields such as science, technology, engineering and math. In this interview she shares some of what they've learned.

What do a commuter taking a detour on the way to work and a youngster fashioning a bird out of a sheet of brightly colored paper have in common? They’re both depending on spatial cognition to complete a task.

Being able to interpret the three-dimensional world around us and to use that information to solve problems is an often-overlooked skill, says Tufts psychologist Holly Taylor. That ability benefits both adults and children in myriad ways, from helping drivers navigate to preparing kids for their future careers.

The trouble is that some of our beloved electronic devices could be a detriment to spatial cognition.
Taylor, a professor in the School of Arts and Sciences, studies spatial cognition and comprehension. In her lab, she and her colleagues have investigated such topics as the effect of navigational aids on memory and whether learning the Japanese paper art origami can increase children’s abilities in all sorts of practical fields such as science, technology, engineering and math.

In one study, she and doctoral student Aaron Gardony looked at subjects who had to find their way through a virtual neighborhood, both with and without navigational aids such as a GPS. In the end, all of them navigated from point to point just as efficiently, regardless of whether they had the GPS. But Gardony’s work also showed that the use of navigational devices actually impaired their memory of where they had been.

Tufts Now: How could people do just as well without the GPS device as with it?

Holly Taylor: People use GPS because they feel they’ll navigate more efficiently, and they see it as a security blanket, to some extent. What we found is that only very early on when navigating from point to point to point in an unfamiliar environment did people with the navigational aid do better than people without it. Very quickly, the people without the navigational aid seemed to learn the environment and navigate just as efficiently as those with the GPS.

But people who had the navigational aid had significantly worse memory about what was around them. And this was on multiple different measures, such as pointing from one landmark to another or drawing a map of the environment.

Why is that?

One of the main reasons is that the GPS draws attention away from the environment.

But don’t some people just have a terrible sense of direction? Wouldn’t the navigational aids have helped them?

There are individual differences, and this is not to discount that some people are better at spatial tasks. But we had each subject working both with the navigational aids and without, and across the whole group, this was what we found.

This doesn’t sound like good news for the GPS companies.

Navigational aids are not going to go away. People feel more comfortable having them, as sort of a crutch. But they don’t seem to have the benefits for navigating that people attribute to them. If you put yourself in the environment and navigate through it, you can do pretty well, and you’ll remember it better.

So what’s the lesson from this?

People should re-engage with their environment, rather than offloading to GPS or smartphones. By paying attention to your environment, you can learn it, so that when things go wrong—your GPS stops working, it gets stolen, you’re in somebody else’s car, there’s a detour somewhere and you can’t stay on the usual path—you’re able to do it. It also sets the wrong example for kids. Seeing their parents always using a device—that sort of suggests that it’s the thing to do, that navigating through your environment and figuring out where things are is not the way to do things.

Speaking of children, you have also done research that supports the idea that improving spatial cognition helps them do better in the STEM (science, technology, engineering and mathematics) fields.

There’s a lot of work that’s been done over the past 35 years looking at spatial abilities and how that relates to retention, perseverance and ability in the STEM disciplines. My work relates to training in spatial skills, and it’s been shown very nicely that such training is effective. In my work, kids engage in origami and pop-up paper engineering lessons. After doing so, they did better on standard measures of 2D-to-3D mental transformations. What we’ll be looking at next is the question of whether this training translates to performance in STEM disciplines.

You’re involved with a spatial cognition program called Think3d! in elementary schools in rural Vermont and New Hampshire. What’s that?

The approach that my collaborator, Allyson Hutton, who is an architect, and I have used is a program that employs origami and pop-up paper engineering to help young students translate two-dimensional objects into three-dimensional ones. Some of this has also been done with college students.

We don’t actually teach origami—we don’t say, “Now fold this, and then fold this.” We say, “Here are the diagrams and instructions; you figure out how to do it.” Or we use reverse engineering, and we show them an origami object already made, and tell them to take it apart. Figuring out how to make or modify objects has been shown to help people make great gains in spatial thinking.

Are there other methods of teaching these skills?

In other studies, researchers have used perspective drawings and even video games, such as first-person shooter games, all of which have been shown to improve spatial thinking and have been linked to improved STEM outcomes.

I don’t have very good spatial abilities. Do you mean playing Call of Duty could improve them?

It may not hurt to try it.

More Earthquakes for Chile? Seismic gap has not been closed

Date:              April 4, 2014

Summary:

After the strong earthquake that struck Chile on April 2 (CEST), numerous aftershocks, some of them of a considerable magnitude, have struck the region around Iquique. Seismologists doubt that the strong earthquake closed the local seismic gap and decreased the risk of a large earthquake. On the contrary, initial studies of the rupture process and the aftershocks show that only about a third of the vulnerable zone broke.

After the strong earthquake that struck Chile on April 2 (CEST), numerous aftershocks, some of them of a considerable magnitude, struck the region around Iquique. Seismologists from the GFZ German Research Centre for Geosciences doubt that the strong earthquake closed the local seismic gap and decreased the risk of a large earthquake. On the contrary, initial studies of the rupture process and the aftershocks show that only about a third of the vulnerable zone broke. 

This vulnerable area is referred to as the seismic gap of Iquique and a strong earthquake is expected to strike here. The Pacific Nazca plate meets the South American plate at South America's west coast. "In a subsea trench along the coast, the Pacific Ocean floor submerges beneath the continent buildinumerous aftershocks, some of them of a considerable magnitude, have ng up tension that is released in earthquakes," explains Professor Onno Oncken of the GFZ. "In the course of about 150 years the entire plate boundary from Patagonia in the South to Panama in the North breaks completely with a segmented series of strong earthquakes." This cycle has been completed except for a last segment west of Iquique in northern Chile. As expected, the strong earthquake of April 2 took place exactly at this seismic gap. 

No All-Clear 

Initial analyses conducted by GFZ seismologists have shown that there is no sign that tension in the earth' crust has significantly decreased: "So far tension has been released only in the central section of this vulnerable zone," Oncken further explains. The series of earthquakes began on March 16 with a 6.7-magnitude earthquake. Although the main earthquake with a magnitude of 8.1 broke the central section of the seismic gap of a length of some 100 kilometres, two large segments further north and south remain intact, and these segments are able to cause strong earthquakes with a high risk of ground shaking and tsunamis.Oncken: "This means that the risk of one or even several earthquakes with a magnitude clearly above 8 still exists." Furthermore, the location and magnitude of the aftershocks suggest such a scenario. 

Since the main quake struck, hundreds of aftershocks have been registered, the strongest that of April 2 (CEST) of a magnitude of 7.6. This earthquake struck about 100 kilometres south of the main earthquake's epicentre. Together with the its associated aftershocks, it forms a second rupture zone. 

Scientists getting ready for a field trip 

For such extreme events, the GFZ has a task force called HART (Hazard and Risk Team) that will travel to the area affected to conduct further studies. The assignment aims at gaining a better and more detailed understanding of the rupture process based on the aftershocks, and defining the rupture surface more precisely based on the distribution of the aftershocks. Currently 25 seismometers are being prepared for air transport. Early next week a team of eight GFZ scientists will fly to Chile. The 25 portable seismometers will be used to expand the existing observatory network IPOC (Integrated Plate Boundary Observatory Chile) in order to be able to determine the earthquake epicentres more precisely. In addition highly precise surface displacements will be measured at 50 GPS measuring points. Two new additional continuous GPS stations will be installed to determine how the earthquake has deformed the earth' crust. 

The Helmholtz Centre for Ocean Research Geomar in Kiel intends to support the measuring campaign. Ocean floor seismometers will supplement land-based seismic data by providing measurements of the aftershocks on the seafloor. 

The Plate Boundary Observatory IPOC in Chile 

The GFZ initiated the setup of an observatory directly within the seismic gap in northern Chile in order to be able to precisely measure and capture tectonic processes before, during and after the expected strong earthquake. The observatory called Integrated Plate Boundary Observatory Chile (IPOC) is a European-American network of institutions and scientists. Together with several Chilean and German universities, German, French, Chilean and American non-university research institutions operate a decentralized instrumentation system located at Chile's convergent plate boundary to gather data on earthquakes, deformations, magmatism, and surface processes. 

The mission succeeded in the case of the April 2 earthquake: "All our instruments survived the quake and aftershocks unscathed. We now have a set of data that is unique in the world," says GFZ seismologist Günter Asch with a smile, who was responsible for checking the instruments on site right after the earthquake and who is once again on his way to the region. "We believe that these data will help us understand the entire earthquake process -- from the phase that tension builds up to the actual rupture, and also during the post-seismic phase." This understanding will provide insights into earthquake risks in this part of the world as well as elsewhere. 

The IPOC will further expand. To this day more than 20 multi-parameter stations have been set up. They comprise broadband seismographs, accelerometers, continuous GPS receivers, magneto-telluric probes, expansion measuring devices and climate sensors. Their data is transferred to Potsdam in real time. The European Southern Observatory on Cerro Paranal is now also part of the observatory network.

Where everyone in the world is migrating--in one gorgeous chart

Finally, world migration in one (relatively) easy to use graphic!

Original Source: Quartz 

By Nick Stockton @StocktonSays March 27, 2014

These flows represent 75% of human migration from 2005-2010. (NB only flows over 50,000 are displayed.) Circos/ Krzywinski, M. et al.

It’s no secret that the world’s population is on the move, but it’s rare to get a glimpse of where that flow is happening. In a study released in today’s Science, a team of geographers used data snapshots to create a broad analysis of global migrations over 20 years.

The study was conducted by three geographic researchers from the Wittgenstein Centre for Demography and Global Human Capital in Vienna. The researchers presented their data in five-year increments, from 1990 to 2010. Their research is unique, because it turned static census counts from over 150 countries into a  dynamic flow of human traffic.

Migration data is counted in two ways: Stock and flow. “The stocks are the number of migrants living in a country,” says Nikola Sander, one of the study’s authors. Stock is relatively easy to get—you just count who is in the country at a given point of time. Flow is trickier. It’s the rate of human traffic over time.

Keeping accurate account of where people are moving has stymied the UN, and researchers and policy-makers in general, for a while. The European Union keeps good track of migrant flows, but elsewhere the data are sparse. Static measurements are plentiful, but it is hard to use them to get a picture of how people are moving on a broad scale, because each country has its own methodology for collecting census data.

Last year, however, the UN brought stock data from nearly 200 countries into harmony by erasing the methodological seams between them. To turn this stock data into five-year flow estimates, the researchers used statistical interpolations from stock data from the UN, taken mostly from 10-year country censuses, but supplemented with population registers and other national surveys.

It’s not the poorest who migrate the most

While the results of the migration study aren’t particularly groundbreaking, there are two interesting insights:

1) Adjusted for population growth, the global migration rate has stayed roughly the same since around  since 1995 (it was higher from 1990-1995).

2) It’s not the poorest countries sending people to the richest countries, it’s countries in transition—still poor, but with some education and mobility—that are the highest migratory contributors.

“One of the conclusions they make in the paper, is the idea as countries develop, they continue to send more migrants, and at some point they become migrant-receiving regions themselves,” says Fernando Riosmena, a geographer from the University of Colorado, who did not contribute to this research, but is collaborating with one of the authors on a future paper.

A few other noteworthy results:

1) The largest regional migration is from Southeast Asia to the Middle East. This is largely driven by the huge, oil-driven, construction booms happening on the Arabian Peninsula.
2) The biggest flow between individual countries is the steady stream from Mexico to the US. (In fact, the US is the largest single migrant destination)
3) There’s a huge circulation of migrants among sub-Saharan African countries. This migration dwarfs the number leaving Africa, but the media pay more attention the latter because of the austerity-driven immigration debates in Europe.

Explore the world of migration

The data aren’t perfect. Riosmena points out that in countries that especially dislike migrants, like the US and Europe, numbers are often underreported. Still, he says, the data are a very good indication of the general trends.


Also, amateur data sleuths be warned: Because these flow estimates are taken from 10-year static counts, they cannot be compared to the annual migrational flows that the UN publishes (which, as mentioned above, cannot be used to compare between countries).

Sander says she hopes her data will change the way other researchers approach migration. “Inside the discipline, we hope that it’s going to be the basis for subsequent analysis of the impact of migration on population, on economies, on aging.” Sander and her colleagues have lined their data up with global remittance flows, and are analyzing what kind of patterns they can find therein.

Beware the risks of smartphones and tablets in schools - I knew it!

Beware the risks of smartphones and tablets in schools

I have been saying something similar for years. Now the experts agree!

Article By: Sachin Maharaj Freelance Opinion writer, Published Toronto Star, on Wed Apr 02 2014

While electronic devices like smartphones and tablets offer many learning benefits, we should be cognizant of the potential downsides.

School boards are embracing the use of smartphones and tablets as learning tools for students in class. But Sachin Maharaj says we should be aware of the potential downsides of pervasive electronic use on young people.

After initial reluctance, school systems appear to be rapidly embracing the use of electronic devices in classrooms. In 2010, former premier Dalton McGuinty reversed an earlier position and publicly supported the use of smartphones in schools, touting their ability to be used as learning tools. In 2011, the Toronto District School Board followed suit and overturned its previous ban of devices in classrooms.

Tablets like the iPad, once considered an expensive luxury, are increasingly becoming a must-have learning item. The Los Angeles Unified School District recently decided to spend more than $1 billion to give every one of its students an iPad. Many schools across Canada are now either buying iPads for their students or actively encouraging them to bring their own smartphones and tablets to class.

The momentum appears to be unstoppable. But while electronic devices certainly offer many learning benefits, we should be cognizant of the potential downsides.

First, as many teachers will know from first-hand experience, while these devices can be valuable learning tools, they are often not used that way. Instead of focusing on the lesson or task at hand, many students find the compulsion to use their phones to play Candy Crush or browse Facebook, Twitter, Vine, Instagram et al. much too tempting. This should be no surprise given what we know about impulse control and the developing adolescent brain.

And even when safeguards are put in place to ensure the devices are used for learning, they are often no match for students’ ingenuity. Almost immediately after students in Los Angeles were given their iPads, the tablets were hacked, loaded up with social media apps, and students started accessing unauthorized websites.

Apart from these issues, given how pervasive electronic use is in all of our lives already, should we really be encouraging even more of this in our schools? Canadians with smartphones already spend an average of eight hours per day staring at electronic screens, not including time spent on computers or mobile devices for work. One Stanford University study found that 75 per cent of iPhone users regularly fall asleep with their phones in their bed. Another study found that almost a third of 16- to 25-year-olds check and update their social media accounts while in the middle of using the bathroom.

Perhaps most worrying are the effects that all of this constant technology use can have on students’ cognitive and emotional development. As noted in a recent feature on CBC’s The National, such high amounts of screen time reduce opportunities for quiet reflection, a key to developing empathy for others. This may go some way to explaining the prevalence of cyberbullying among teens.

It is also having an impact on the values our children hold. Whereas teens used to be mostly concerned with fitting in with their social groups, their primary concerns now seem to be acquiring attention and fame. As one Grade 6 Nova Scotia student put it: “I like it when people like my pictures, it makes me feel really good . . . who doesn’t want to be famous?”

Constant electronic use can also carry a significant cognitive cost. Indeed, researchers in Britain found that excessive use of technology reduces people’s intelligence more than twice as much as heavy marijuana use. The incessant barrage of electronic information also makes us less patient. A study by Microsoft and Google found that just a mere 250-millisecond delay in the time it takes to load a web page is enough for most people to abandon it entirely.

Other studies have shown that as our devices and networks get even faster, our impatience only grows. It also seems to be reducing our attention span. Consider the finding that people who read newspapers read for an average of 25 minutes, whereas people who read news online read for an average of 70 seconds.

The implications for our students are profound: it can make them less likely to want to experience things that take long periods of time or that do not provide instant gratification. But learning about and truly appreciating the natural world, as well as the great works of humanity, often require both significant time and patience. It is also what is necessary for students to engage in deep and creative thinking of their own. So while electronic devices may have benefits, perhaps we should rethink embracing them with such open arms in our schools.

UN report on climate change rings alarm on warming polar regions

Second of three reports by UN Intergovernmental Panel on Climate Change released Monday in Japan warns that Arctic sea ice is declining faster than models projected.

Spencer Wynn / Toronto Star

Arctic sea ice cover and volume are declining faster than models projected, warns John Stone, the lead author on the polar regions chapter of the new UN report on climate change.

By: Raveena Aulakh Environment, Published in the Toronto Star, March 30, 2014

The world is warming up and the impact of climate change is already being seen across the globe, an authoritative new UN climate report says.

But in this part of the world, which is barely out of the clutches of a long and wicked winter, the report sounds like a conundrum.

Make no mistake, the world is warming up, especially the Arctic, said John Stone, an IPCC lead author and adjunct professor at Carleton University.

“What we have experienced this winter is just weather,” said Stone. “It may have been cold in large parts of North America, but Alaska was unusually warm and Norway and other Scandinavian countries have been abnormally warm, too.”

Most of Europe has also had warm weather this year, he added.

“When you are looking at climate change, you just cannot look at one region of the world. You’ve got to look at the whole world together and you can’t look at one year, you have to look at the trend.”

The past 150 years indicate that climate has changed, he said.

The second of three reports by the United Nations Intergovernmental Panel on Climate Change was released in Japan on Monday. It warns that governments are ill-prepared for a warming world and if action is not taken soon, risks could become unmanageable.

The impact and adaptations in polar regions are a big part of the report.

Stone, the lead author on the polar regions chapter, pointed out that warming there has already led to a decrease in Arctic sea ice cover and volume. “It is declining faster than any of our models projected,” he said, adding that it suggests “to some of us that climate change may well be accelerating.”

The Arctic, said Stone, could be clear of sea ice in summer within the next few decades, “rather than the end of the century as was previously estimated. . . ”

It may be very hard for Arctic communities to adapt, he said.

The accelerated rates in permafrost thaw, loss of coastal sea ice and sea level rise are forcing some communities, particularly in Alaska, to relocate, said Stone.

“It is an expensive and culturally difficult exercise.”

The report says, without ambiguity, that there are risks to the “health and well-being of Arctic residents, resulting from injuries and illness from the changing physical environment, food insecurity, lack of reliable and safe drinking water, and damage to infrastructure, including infrastructure in permafrost regions.”

In an emailed statement, Environment Canada said that through the Arctic Council scientists are engaged in “climate change adaptation activities that advance our understanding of the range and extent of impacts of climate change in the Arctic region.”

It also said that an online adaptation information portal will be set up to help people there understand and adapt to climate change.

The IPCC report also sheds light on the new reality of property insurance versus extreme weather, especially in North America, where companies have experienced increases in severe weather damage claims in the past couple of decades.

(The flooding in southern Alberta in June 2013 was the costliest natural disaster in Canadian history, with $6 billion in losses, according to a January report by Munich Re, the world’s largest reinsurance firm.)

Meanwhile, Monday’s IPCC report also warned of decreased crop yields, losses due to forest fires and coastal erosion in North America.

“Climate change is more than just an environmental issue,” Ian Bruce, science and policy manager with the David Suzuki Foundation, said. “This is an economic and security issue that will impact everyone from the biggest cities to the smallest towns.”

In September, the first part of the IPCC report warned that Canada will continue to see more warming than the global average and extreme weather events will be more frequent and more intense.

Denmark Needs Babies so Danish Businesses Take on Population Decline

Taking on the problems associated with an aging and declining population!

A Danish travel company is calling for Danes to have more sex while they’re on holiday – to save the country. They even launched a competition to encourage the people to take a break and conceive kids, as the birthrate is now at its lowest in decades.

Spies Rejser Travel has promised three years of free baby supplies and a child friendly holiday for a couple who can prove that they conceived while on a Spies’ holiday. The travel company said it is trying to help tackle the country’s low birth rate by encouraging couples to do it for Denmark.

The birth rate in Denmark is currently the lowest it’s been in 27 years. Almost 58,000 children were born in 2012, but the present rate of 1.7 children per family is not enough to maintain the population. 

Warning:  Mildly Not Safe for Work/Children

Eva Lundgren, a spokeswoman for Spies, said that sexologists believe one of the reasons for the low birth rate is that Danes are too busy to have sex.

“Sex specialists believe that Danes are too busy with their daily life and they need to get away, so we hope we encourage people to take a break and have some romance,” she told RT.

The thinking behind the initiative is that a couple’s desire for each other increases while they are taking a break together.

Couples who enter the competition are sent a pregnancy test after the holiday and if it comes up positive, they must send in a picture of the test result to Spies as proof.

Entrants are given a list of romantic cities and the website then asks women to enter the date of their last period so they can take a trip when they are at their most fertile.

There are even useful tips for increasing fertility such as “take advantage of gravity. Lie down for at least 15 minutes after sex.” Men are also advised not to wear tight pants “even if you think it looks good.”

A report published in February described the birth rate among Danish women as “dangerously low” and found that one in five couples in Denmark are childless.

“Many wait too long to have children, creating a greater need for fertility treatments. There is a need to raise awareness, as the problem is approaching epidemic levels,” Soren Ziebe, a clinical supervisor at Rigshospitalet, wrote in the report.

The study noted that in the 1970s the average Danish woman was 24 years-old when she gave birth to her first child. Today the age is 29, but a greater number of women are waiting until they are over 35. As a result more and more couples are relying on fertility treatments to conceive.

But do it for Denmark isn’t just about increasing the birthrate and is also a bit of fun.

“What if you already did your duty? Or what if your chance of conceiving a child isn’t so high,” asks the advert, filming an old couple followed by two gay men.

“Well look at it this way. It’s not just about winning. All the fun is in the participation.”
