Global warming will bring more heavy snow in northern Japan
Logic would tell us that continuing global warming will lead to less snowfall, but the opposite will be true in some areas of northern Japan, according to a meteorological simulation.
By the end of this century, while the country as a whole will receive a smaller amount of snow, Hokkaido and inland areas of the Hokuriku region will experience more frequent heavy snowfalls, the Meteorological Research Institute of the Japan Meteorological Agency announced Sept. 23.
The reasoning behind the prediction is that larger amounts of water vapor in the atmosphere caused by higher temperatures will make it easier for belts of snow clouds to develop above the Sea of Japan when the air pressure pattern is typical of the winter.
According to the results of the institution’s precise simulation, the Japanese archipelago will have lighter snowfall during the winter, if the mean annual temperature increases three degrees from the current level between 2080 and 2100.
Tracking original source material is a bit tricky because I don’t read or write Japanese, but the following appears to be part of an official Japanese Meteorological Report – though I am not sure if it is the source material referenced by Yoshida.
HARBOR, Ore. (AP/WATE) – Transportation officials say a massive sinkhole has opened near a highway along the coast of southern Oregon.
Kyle Rice, posted a YouTube video of drone footage of the massive sinkhole from a bird’s eye view. Oregon. The Oregon Department of Transportation says the sinkhole off Highway 101 has been plaguing the Curry County town of Harbor since heavy rains last month.
A contractor was working on it Thursday when the erosion started to accelerate on a nearby road. Officials say the sinkhole didn’t swallow any vehicles, and there were no injuries. Signs have been placed along the highway directing traffic to a detour. ODOT spokesman Jared Castle says drivers can expect delays of five to 10 minutes.
The agency plans to get bids from contractors so repairs can start quickly, but repairs could be upwards of $4 million according to ODOT. Castle says ODOT wants the road partially opened within a week, but the entire repair could take eight weeks.
Research conducted by U Ph.D. student Patrice Kurnath finds that at warmer temperatures the toxin tolerance of certain mammals is reduced — adding yet another problem to the growing list of environmental complications due to global warming.
Plants often generate toxins as a natural defense. Desert woodrats, the plant-eating species used by Kurnath and chair of the U’s biology department Denise Dearing in the study, generate certain enzymes to counteract the effects of these toxins that are ingested when consuming the plants.
“We’re answering the big question of how warmer temperatures might be affecting animals that eat plants and how they deal with the toxins produced by those plants,” Kurnath said.
The diet of desert woodrats, which are common in Utah and western North America, consists mainly of creosote bush, which produces so many toxins in its resin that laboratory rats often die eating the same amount as the desert woodrats.
The idea behind the experiments hypothesized that as woodrat toxin tolerance levels decreased with temperature increases, that they would reduce food intake and lose weight. Woodrats were removed from the experiment if they lost more than 10 percent of their body weight.
“[Kurnath] really pushed the envelope with this work and expanded knowledge from a different study,” Dearing said. “Not only did she work with different species and a different toxin, she did processes and experiments we have never done before.”
Desert woodrats were able to eat more food at cooler temperatures in both experiments at the end of the research, while almost all of the woodrats in higher temperature climates were removed due to weight loss.
“The most recent study found that warmer temperatures resulted in reduced tolerance in rats,” Kurnath said.
This research adds another dimension to the problems associated with global warming for these species as they deal with an increasingly more toxic diet.
“Not only are surface temperatures increasing, severe weather storms, this is another obstacle that these woodrats and other species are going to have to face,” Kurnath said.
Kurnath plans to extend the study by “digging deeper” into the liver functions and genetic structure of these mammals consuming a highly toxic diet and by “stepping back” and examining their behavior in lab settings. Dearing is working on studying this same trend in marsupials and expects to see results by next year.
Dearing said, “We hope that it will inspire research in other species of mammals.”
KOIN 6 Meteorologist Kristen Van Dyke says the system will be a windy one, with gusts on the coast reaching 55 mph.
Winds will also pick up in the Portland metro area with gusts up to 30 mph overnight and even 40 mph on Thursday. This could bring down large branches and even some trees, so be careful out on the roads.
There will be a lull in the rain after morning with a round of heavy, blustery showers pushing in Thursday evening.
Freezing temperatures will mean more ice and freezing rain in the Gorge overnight and into Thursday. A rise in temperatures will scour out the cold air and turn the ice back into rain in the afternoon.
Thankfully, the ice will be confined to the Gorge as temperatures in the valley warm up to the 40s overnight.
You can expect wetter weather on and off through early next week. There’s no sunshine in our immediate future, but temperatures are expected to be much milder with highs in the 50s.

It’s not really the most wonderful time of the year unless there is snow involved. Fact.
This is your reaction when it snows (Photo: Dan Kitwood/Getty Images)
Not only can snow be the greatest part of the British weather experience, but it also guarantees more happiness than a decent summer season.
Ah snow. Word on the street (the street being the Met Office) is that we are due a sprinkling of snow, with many places across the UK being treated to a flurry last night.
And snow lovers couldn’t be happier about this.
1. So PRETTY
Of course autumn is really beautiful, what with the leaves all turning to a cosy shade of orange. However, not even the prettiest autumn scene, trees lining a path through an empty park, could ever trump a field full of freshly fallen, untouched snow.
2. Makes Christmas better
There are only two things that could make Christmas Day even better; meeting Santa Clause, or a white Christmas.
Nothing could match the warm fuzzy feeling of waking up early in the morning on Christmas Day and seeing your street transformed as if it’s been draped in a layer of clean cotton wool.
Bing Crosby felt exactly the same way.
You love nothing more than grabbing a few sticks, buttons, pebbles and the obligatory carrot stick and assembling a small team to make an epic snowman.
Of course you take this very seriously, and every time you pride yourself on having the best snowman on the street.
In fact you have a strict method involving rolling a huge ball of snow down a slope in order to get your snowman as big as possible. You have also been known to shed a tear once he melts away. *Sob*
4. Snow days = best days
There are waves of excitement that still feel the exact same way when you’re an adult as they did when you were a child.
Stuff like watching Home Alone, birthday cake… and snow days.
A snow day feels just as amazing now, when you can’t get into the office, as it did when school was closed.
Especially when you get to the station only to be greeted with signs telling you that all trains are cancelled.
You take this opportunity to power walk home as quickly as possible, alerting everyone you meet on your way that it’s now an official snow day, whilst being busy with thoughts of how to make the most of it.
Of course throwing a few snowballs around is mandatory.
5. The memories
It doesn’t matter if your school days weren’t your best days, because the memories of snowy times during school definitely makes up for this.
The only thing to trump the mayhem of times when a dog managed to get into the playground was sitting in Maths and seeing thick heavy flakes falling and engulfing everything.
Most of the time your teachers would give up trying to capture your attention and let you out early which was always welcomed.
6. Perfect for long walks
There is something special about being able to stomp over fresh untouched snow whilst wrapped up head to toe in at least six layers of clothing.
Is there anything better than popping on some wellies and going for a long walk in the crisp cold air whilst feeling the soft snow underneath your feet?
7. Everything stops
Of course some people don’t like the snow because it causes disruption, but this can actually be a good thing.
It’s nice to have a bit of disruption which causes things to come to a bit of a stop, proving that it’s not the end of the world if you don’t manage to answer all your emails before 6pm.
8. Snow watching is intense
The only thing that could ever trump a snow filled walk, is sitting inside near the radiator with a hot drink and watching the snow fall and seeing the world turn into a winter wonderland.
Preferably whilst wearing thick woolly socks.
During this ritual you embark upon an emotional roller-coaster as you are glued to the window desperately wishing for the snow to become thicker, and heavier. Any sign of easing off leads to severe disappointment, which can only be ended by another flurry.
9. It’s very exciting
Waiting for the snow to arrive is a bit like waiting for a baby.
You know that it will come at some point, and despite having a rough time frame you still exhaust yourself with excitement waiting for it to arrive.
Once it finally arrives there is something magical about waking up and being able to tell from the silence outside, and the light reflecting off the snow into your bedroom that your wait is now over.
10. How to deal with haters
Being a lover of snow means you’ve developed a very thick skin to not only deal with the temperature drop, but also all of the people who don’t like the snow.
You’ve figured that if you can convert one snow hater to a snow fan then you’ve pretty much served your purpose on Earth.
11. SLEDGE TIME
You’ve probably got a customised beauty hidden in your garage, or garden shed that you always bring out as soon as the snow lands.
You also know the best parks within a 10 mile radius to go get revel in all the fun that sledging offers. And you head out with a sense of urgency, in order to get the best of the snow before pesky teenagers ruin it all.
12. It’s never enough
Chances are that most years you will end up slightly disappointed, as the UK tends to only get a small sprinkling.
But this just means that when we receive a heavy snow storm, you take full advantage of this rare event by spending as much time as possible outside.
You will even risk mild frostbite and soggy gloves in order to squeeze in as much time as possible in the snow. And it’s well worth it.
13. And it always goes too soon
The fact that snow melts away is one of the biggest tragedies in your life, and each time the sun comes out you are filled with dread.
Especially when it goes from being fresh white pure snow and disintegrates into a brown muddy slushy mess.
The only way to get through this is by remembering all of the good times you’ve had with it, and pinning your hopes on it returning next year. Courtesy of: The Metro UK.
“In a normal thunderstorm, ice crystals collide and generate electric charges,” volcano filmmaker Marc Szeglat, who was not involved in filming the below clip, told BBC Earth earlier this year. “In an eruption cloud, ash particles collide instead of ice crystals.”

The projected upsurge of severe El Niño and La Niña events will cause an increase in storm events leading to extreme coastal flooding and erosion in populated regions across the Pacific Ocean, according to a multi-agency study published Monday in Nature Geoscience.
The impact of these storms is not presently included in most studies on future coastal vulnerability, which look primarily at sea level rise. New research data, from 48 beaches across three continents — including Hawaii — and five countries bordering the Pacific Ocean, suggest the predicted increase will exacerbate coastal erosion irrespective of sea level rise affecting the region.
Researchers from 13 different institutions analyzed coastal data from across the Pacific Ocean basin from 1979 to 2012. The scientists sought to determine if patterns in coastal change could be connected to major climate cycles.
Although previous studies have analyzed coastal impacts at local and regional levels, this is the first to pull together data from across the Pacific to determine basin-wide patterns. The research group determined all Pacific Ocean regions investigated were affected during either an El Niño or La Niña year.
When the west coast of the U.S. mainland and Canada, Hawaii, and northern Japan felt the coastal impacts of El Niño, characterized by bigger waves, different wave direction, higher water levels and/or erosion, the opposite region in the Southern Hemisphere of New Zealand and Australia experienced “suppression,” such as smaller waves and less erosion.
The pattern then generally flips: during La Niña, the Southern Hemisphere experienced more severe conditions.
The published paper, “Coastal vulnerability across the Pacific dominated by El Niño/Southern Oscillation” is available online.
Abstract: To predict future coastal hazards, it is important to quantify any links between climate drivers and spatial patterns of coastal change. However, most studies of future coastal vulnerability do not account for the dynamic components of coastal water levels during storms, notably wave-driven processes, storm surges and seasonal water level anomalies, although these components can add metres to water levels during extreme events. Here we synthesize multi-decadal, co-located data assimilated between 1979 and 2012 that describe wave climate, local water levels and coastal change for 48 beaches throughout the Pacific Ocean basin. We find that observed coastal erosion across the Pacific varies most closely with El Niño/Southern Oscillation, with a smaller influence from the Southern Annular Mode and the Pacific North American pattern. In the northern and southern Pacific Ocean, regional wave and water level anomalies are significantly correlated to a suite of climate indices, particularly during boreal winter; conditions in the northeast Pacific Ocean are often opposite to those in the western and southern Pacific. We conclude that, if projections for an increasing frequency of extreme El Niño and La Niña events over the twenty-first century are confirmed, then populated regions on opposite sides of the Pacific Ocean basin could be alternately exposed to extreme coastal erosion and flooding, independent of sea-level rise.

WINNIPEG – The freezing cold winter weather Winnipeggers have been waiting for is finally here.
Saturday morning was -24C and felt like -38 with the wind chill. Winds will be gusting at about 50 km/h throughout the day.
Overnight temperatures could drop to a low of -35C and with extreme wind chill feel like -45, according to Environment Canada.
Due to the cold temperatures, heavy winds and snow drifting, garbage collection will be slower than normal. The city says crews working will need to take frequent breaks and may need extra time to pull carts out and over the snow in neighbourhoods with manual collection.
The city is currently working on clearing and sanding streets full of snow and ice. Operations began at midnight on Friday.
Only the regular Snow Route Parking effect remains in effect, meaning parking is not allowed between 2:00 a.m. and 7:00 a.m. on streets with “Snow Route”…
The day of Dec. 26, 2004, started with an earthquake, off the coast of Sumatra, and only got worse as the resulting tsunami hit coastal nations throughout the Indian Ocean.
As TIME explained in a special issue devoted to the devastation, the geology behind the tsunami caused a chain reaction of disaster:
Geologists describe the tectonics–the almost imperceptibly slow movement of massive plates–of the southern Indian Ocean as complex because a number of plates converge there. The floor of the Indian Ocean–the Indian plate–is moving north at around 2.5 in. per year, about twice the rate that your fingernails grow. As it moves, it is forced under the Burma plate to its east. Eighteen miles below the surface of the ocean, stresses that had been gradually accumulating forced the Burma plate to snap upward. That was a huge geological event, eventually measured at 9.0 on the Richter scale. The dislocation…
