El Niño brings Christmas chaos

From Paraguay to the US, Australia to Spain, El Niño brings Christmas chaos 



Weather and climate are, of course, very different things. But the sheer concentration of extreme weather events around the world over the Christmas period has lent yet more weight to the idea that the world’s climate is changing, even if the effects are currently exacerbated by the effects of El Niño.

Also a Deltaplan for the UK ?

[From the Guardian] 
When more than 1,800 people died in the wake of the 1953 North Sea flood in the Netherlands, the national reaction was: never again. The resulting Delta programme to close off the south-western river delta from the sea was so bold that its name became synonymous with dealing with a crisis. 

For the Dutch, water management goes to the core of their national identity.The Netherlands has adapted to the changing nature of the threat. Today, the biggest danger is not the sea swallowing the land but the rain overwhelming it. The main focus no longer is building higher dykes and bigger dams, like they did after the 1953 flood. Instead, the Dutch have spent the past decade deepening and widening rivers, creating new side canals that provide extra capacity, and setting aside land as dedicated flood plains. More about "these projects" >>

Some people say the UK needs now also a Dutch-style national response, with the necessary funding. The British landscape demands it even more than the Dutch flat countryside. With heavy rainfall flowing down the hills into lower-lying areas, those places need investment in rivers and landscapes able to absorb that water, transport it away from homes quickly or temporarily store it on empty flood plains. We need to stop building in at-risk areas, setting those places aside as buffers to protect existing homes.

The other Christmas Island and El Nino

Except from the "Australian Christmas Island in the Indian Ocean there is also one in the Pacific. This Christmas Island sits about as close to the middle of the Pacific as you can get.

The main island of Kiribati, a small island nation, is 3,300 miles from San Francisco, 3,800 miles from Brisbane and just 140 miles north of the equator. Its closest neighbor of note is Hawaii, which is still 1,250 miles away.

Some might say it’s as close to the middle of nowhere as you can get. But it’s at the center of one of the biggest climate events in decades. A super El Niño has raised water temperatures to unprecedented levels and it’s causing a massive coral die off.

Mount Etna erupts again

Europe’s tallest active volcano, Mount Etna, has erupted in spectacular fashion, filling the sky above Sicily with flame, lightning, and a gigantic ash cloud.


Mount Etna has been mostly quiet for two years, but after intensifying volcanic activity in recent weeks, things came to a head with the dramatic eruption you can see in the video below.

Heavy smog in Beijing

While the governments of more than 190 countries met in Paris last week for the UN climate change conference to set targets on reducing carbon emissions China’s capital and many cities in the northern part of the country recorded the worst smog of the year with air quality devices in some areas unable to read such high levels of pollutants. Levels of PM 2.5, considered the most hazardous, crossed 600 units in Beijing, nearly 25 times the acceptable standard set by the World Health Organisation.

The eruption of the Nevado del Ruiz in 1985


The Colombian volcano Nevado del Ruiz is an active stratovolcano with a history of generating deadly volcanic mudflows (lahars) from relatively small-volume eruptions.

In 1595, a lahar swept down the valleys of the River Guali and the River Lagunillas, killing 636 people.

In 1845, an immense lahar flooded the upper valley of the River Lagunillas, killing over 1000 people. It continued for 70 kilometers downstream before spreading across a plain in the lower valley floor. The young village of Armero was built directly on top of the 1845 mudflow deposit. Over the ensuing years, Armero grew into a vibrant town with over 27,000 residents.

On November 13, 1985, history repeated itself for the third time in 400 years, with another eruption and another deadly lahar racing down the River Lagunillas.

The eruption was not very alarming, but the lava flow combined with melting snow took everything resulting in a high speed Lahar on his way down.
This time, over 23,000 people were killed, including most of the residents of Armero.

What's Up With the Quakes Before a Volcano Erupts?

EARTHQUAKES AND VOLCANOES are intimately linked. They are both products of the plate tectonic process that is constantly reshaping the surface of the Earth. But even beyond that, earthquakes are some of the best clues we have that a volcano might be heading towards an eruption. So, why are there earthquakes in the days-months-years before a volcano erupts and why do some earthquakes lead to an eruption and some don’t? Well, it is a little more complicated than it seems.

China announces that the One Child Policy is to end

China's Communist party has scrapped its one-child policy, allowing all couples to have two children for the first time in more than three decades 
 
In the late 1970s, the Chinese government introduced a number of measures to reduce the country's birth rate and slow the population growth rate. The most important of the new measures was a one-child policy, which decreed that couples in China could only have one child.

Five migrant stories from Greece

Almost 600,000 refugees and migrants have made their way across the Mediterranean to Europe this year and the majority of those have landed on the Greek islands closest to Turkey.

Migration experts say the numbers arriving on the islands have surged recently to as many as 7,000 a day, trying to reach Europe before the weather worsens. The biggest numbers arriving in Greece are from Syria, Afghanistan, Iraq and Pakistan and some of the new arrivals on the island of Lesbos told BBC News their stories.

Arctic Sea Ice Minimum Volumes 1979-2015

This is an animated visualization of the startling decline of Arctic Sea Ice, showing the minimum volume reached every September since 1979, set on a map of New York with a 10km grid to give an idea of scale. It is clear that the trend of Arctic sea ice decline indicates that it'll be ice-free for an increasingly large part of the year, with consequences for the climate. The rate of ice loss in the Arctic is staggering. Since 1979, the volume of Summer Arctic sea ice has declined by more than 80% and accelerating faster than scientists believed it would, or even could melt. Based on the rate of change of volume over the last 30 years, I expect the first ice-free summer day in the Arctic Ocean (defined as having less than 1 million km² of sea ice) to happen between 2016 and 2022, and thereafter occur more regularly with the trend of ice-free duration extending into August and October.

Glacier flood on Iceland




The Icelandic Meteorological Office has announced that the eastern Skaftárketill caldera in Vatnajökull glacier is emptying into the Skaftá river.

Large amounts of water collect in the calderas under the glacier due to volcanic and geothermal activity which melts the glacier above. The calderas have emptied on average every two years, causing massive flooding in the Skaftá river.

The Glacier flood may reach the Iceland national ring road

Mapcode

From the founders of Tomtom .

A mapcode represents a location. Every location on Earth can be represented by a mapcode. Mapcodes were designed to be short, easy to recognise, remember and communicate. They are precise to a few meters, which is good enough for every-day use

Mapcodes are a free, open way to make every house or location on Earth addressable by a short code. With nothing else except your mapcode, for instance, a navigation system will bring someone to within meters of your front door.

Syrians fleeing war find new route to Europe – via the Arctic Circle


Dozens of Syrian migrants have trekked to the far north of Russia this year in an unlikely bid to reach a little-known Arctic border crossing with Norway Up to 20 Syrians a month are crossing into the tiny Norwegian town of Kirkenes, where the average daily temperature hovers just below freezing.

 They tried the shores of Libya, the islands of Greece, and the plains of the Balkans.

Now it has emerged that Syrians fleeing civil war have found another route to the safety of Europe: the Arctic Circle.

Doggerland’s lost world

During the last Ice-age Great Britain was directly connected to the European continent.





About 100 km northwest of the Dutch coast we find today "The Doggersbank". A seabank in the middle of the Nortsea. An that is all what's left from Doggerland, essentially an entire prehistoric European country.
Looking at the area between mainland Europe and the eastern coast of Great Britain, you probably wouldn’t guess it had been anything other than a great expanse of ocean water. But roughly 12,000 years ago, as the last major ice age was reaching its end, the area was very different. Instead of the North Sea, the area was a series of gently sloping hills, marshland, heavily wooded valleys, and swampy lagoons: Doggerland.
However as a result of the sea level rising in the Holocene Doggersland disappeared beneath the North Sea.

National Geographic Education Has now produced a interesting map of Pleistocene Europe

This data entry visualizes how infant mortality decreased over the last 2 centuries. Visualize the data on a series of world maps if you want to study how infant mortality is now decreasing around the world. This fundamental change contributed to the rapid increase of life expectancy of people around the world. Before the onset of modernity every 4th child died before its first birthday. Over the course of modernity the mortality of infants (children below 1 years of age) declined rapidly – first in the countries that industrialized early and now in countries around the world. This is shown in the following time series plot. [source : Our world in Data by Max Roser )

Optimism for the Aral Sea ?


The Aral Sea is situated in Central Asia, between the Southern part of Kazakhstan and Northern Uzbekistan. Up until the third quarter of the 20th century it was the world's fourth largest saline lake, and contained 10grams of salt per liter. The two rivers that feed it are the Amu Darya and Syr Darya rivers, respectively reaching the Sea through the South and the North.

 The Soviet government decided in the 1960s to divert those rivers so that they could irrigate the desert region surrounding the Sea in order to favor agriculture rather than supply the Aral Sea basin. The demise of the Aral Sea in central Asia was caused primarily by the diversion of the inflowing Amu Dar’ya and Syr Dar’ya rivers to provide irrigation water for local croplands.

These diversions dramatically reduced the river inflows, causing the Aral Sea to shrink by more than 50%, to lose two-thirds of its volume, and to greatly increase its salinity. At the current rate of decline, the Aral Sea has the potential to disappear
However A new study using data from NASA satellite missions finds that, although the long-term water picture for the Aral Sea watershed in Central Asia remains bleak, short-term prospects are better than previously thought.

The melting season of Greenland’s ice sheet

It appears that Greenland’s melt season is making up for lost time. 

After a cool spring kept Greenland’s massive ice sheet mostly solid, a (comparatively) warm late June and early July have turned half the ice sheet’s surface into liquid, well outside the range of normal for this time of year.

 Despite the ice sheet’s remote location, its slushy fingers reach across the globe, influencing sea levels and how fast the Gulf Stream current moves. As temperatures rise, its influence could grow larger as major summer melt events become regular occurrence.

Recent warming has already contributed to ice loss in some areas previously thought to be stable and sped the trip of some glaciers into the sea.
