The National Snow and Ice Data Centre has reported that snow cover in the US is decreasing over time. Here is a snapshot of what that means in one US state, Wisconsin:

Yes, Booby, snow may fall but does it hang around for long and does it persist or fairly rapidly melt? Watching all those 500 YouTubes has rotted your brain.

Robert Scribbler on the Californian fires:

https://robertscribbler.com/2017/12/22/toasted-californias-2017-foreshadowing-of-the-monster-fires-to-come/

Wettest winter ever then the hottest summer, drying out the growth caused by winter rains, dried it out until it was flammable. Winds spreading the fires.

1. This is what weather and 1.1°C temperature rise brings

2. Can’t say there is a month in California where no fire can burn.

Dead or dying coral reefs a consequence of AGW:

The trend in tropical sea temperatures continues inexorably upward, and high temperatures lead to coral bleaching. Climate change is happening more quickly than many imagined it would. The bleaching event of 2016 may not have been repeated as severely in 2017, but those circumstances will reproduce themselves soon enough, probably during the next El Nino event – these too are slated to become more severe. Scientists are now concerned about how early in the season bleaching has begun this year. Any bleaching events in close succession will kill parts of the reef that are not already dead.

I read about the pine bark beetle years ago. Winters in Canada no longer cold enough to kill nearly all pine bark beetles so with spring the pest started feeding and breeding, devastating wide swathes of forest. Now the pest has jumped the rockies and is threatening another species of conifer:

Fish face problems from AGW. If the water in their preferred bit of see is too cold they can’t bask in the sun like a lizard and they can’t shed heat if the water heats up. All they can do—migrate.

http://www.nationalgeographic.com.au/animals/more-sharks-ditching-annual-migration-as-ocean-warms.aspx

This year has been strange,” Kajiura says. “Last year was unusually warm all winter: The water temperatures never got below 23 degrees Celsius. This year, the temperatures have risen dramatically to 26 degrees Celsius. It’s now even hotter than this time last year


It means fishermen may have to travel further to catch the desirable fish and that means more $$$ and higher prices.

The immediate face of AGW: sea level rise and the increased flooding it brings (fires are also an immediate face but fires have been with us a long time so people turn their face away so they don’t have to think:)

Sea Level Rise in the United States — From Nuisance to Trouble

As fossil fuel companies fight to keep cities and nations captive to harmful emissions, the effects of rising greenhouse gas concentrations are growing more and more pronounced.

A new study from NOAA finds that the incidence of coast flooding along the U.S. coasts (primarily driven by fossil fuel burning) has increased considerably. This already-damaging situation, under present emissions scenarios, is expected to become much worse over the coming decades.

In the Southeast, high tide flooding days since 2000 have increased from an average of 1.5 per year to 3 per year. In the Northeast, similar flooding days have increased from about 3.5 per year to 6. Flooding is also becoming more common on the U.S. West Coast, though at a slower rate of growth. But hotspots for this region include San Francisco — which is seeing both land subsidence and rising oceans.

Image



https://robertscribbler.com/2018/03/09/sea-level-rise-in-the-united-states-from-nuisance-to-trouble/

I read the Wired article on sea level rise/land subsidence in SanFran, similar obtains on parts of the east coast of the US—balancing the lack of kilometre thick ice sheets means some land rises and some sinks.

Holland, of course, is the poster child for land subsidence, being largely a delta plus parts reclaimed from the sea (read up on the Zuiderzee dike) but, due to weird gravity effects and proximity to Greenland is not facing rising seas, not yet anyway.

The graphs show the difference between the US west and east coasts (SanFran is a very local effect) with sea level rise zooming on the east coast.

One consequence is shortage of water.

We know Cape Town is in dire straits but in the US Miami, Los Angeles and others are too.

In the case of Miami—the sea is encroaching onto under- and above- ground water sources. In the case of LA—the snow pack in the Sierras is way too low for ensured water supplies.

In Australia—the southern half of the country is drying out according to the BuMet (Search here for: State of the Climate 2016 report.)

BTW—sorry Pinky—Lees’ claim that glacier retreat/sea level rise is due to adjustment to the Little Ice Age ending is hogwash.

The “Little Ice Age” was not really an ice age. Temperatures in the LIA were like 0.5°C cooler than temperatures in the early 20th century. It was felt mostly in England and north east of the USA and likely due to the ending of the Gulf Stream.

So, forget about that bit of nonsense.

Three major storms, two of which involved “bombogenesis” (a rapid fall in barometric pressure) have hit the NE coast of the US in two weeks. The first produced huge waves which have caused flooding in Boston and other areas—sea level rise is highest off the east coast of the US.

So what is going on?

Atmospheric Train Wreck

Looking for causes, we need to go all the way back to February. At that time, a big polar warming event was taking place. In the upper levels of the atmosphere over the pole, the stratosphere was warming up. But at the same time, surface temperatures at the pole were rising to above freezing. In some locations near Northern Greenland, readings were pushing as high as 63 F above average.

High amplitude Jet Stream waves were eating away at the typically faster polar circulation patterns even as they were helping to inject much warmer than normal air into the Arctic and pull its resident cold air out. Eventually, all this heat running into the various layers of the Arctic atmosphere drove the polar vortex to collapse. This, in turn, resulted in cold Arctic air being ejected south and west into Europe. This massive jet stream dip, in eddy-like fashion produced a large, countervailing high pressure ridge over Greenland.


We all saw this warmth above 80°N reported. The thick ice off the north coast of Greenland disappeared and was replaced by open water. Open water where the thickest ice used to be! 61 days above freezing in the north of Greenland when the sun had been below the horizon for months! Certainly amazing things were happening!

The Jet Stream has become wavy and weaker as I have mentioned more than once. One ridge above Alaska diverted moist air from California and gave it five years of drought. Picture of the Jet Stream at present:

Image
A deep trough that has consistently lingered over the U.S. East Coast and helped to spawn storm after powerful storm, was initially generated by a very intense polar warming event linked to human-caused climate change. Image source: Earth Nullschool



The Gulf of Mexico is several degrees hotter than normal and the Gulf Stream in the North Atlantic is warmer than usual. (As an aside, another dupe on Twitter asked wtte “Gulf of Mexico is hotter by 5°C is there a volcano or vent underneath it?” because they cannot think anymore.) No, there is no volcano or vent under the Gulf! Plain old sun has raised the temperature of the Gulf, jeez! The warm Gulf and North Atlantic nourished the storms, feeding them energy and moisture like the North Atlantic did to Hurricane Sandy that flooded New York and the easternmost hurricane that almost hit northern England/Ireland/Scotland.

The rippling upper level jumble of winds backed all the way to the U.S. East Coast — forming a deep and persistent trough. The trough funneled numerous disturbances slowly through the region. And it was both the trough’s persistence and depth that enabled strong storms to form repeatedly even as they set off such long-lasting and intense impacts (see Dr Jennifer Francis’s related work on how polar amplification impacts the Jet Stream here).


You can see the patterns in the image above. There is a Jet Stream around Antarctica and that too is being disorganised by AGW and polar amplification.

Much Warmer than Normal Ocean Waters

Though polar amplification — which is another term for how global warming spurs the poles to heat up faster than the rest of the world — helped to generate the upper level features in the atmosphere that would consistently generate storms running across the U.S. East Coast, widespread warmer than normal ocean waters helped to give these storms more fuel.

In the Gulf of Mexico, sea surface temperatures have consistently ranged between 0.5 and 3 C above normal since February. These warm ocean waters contributed to severe floods over the Ohio River Valley at that time by pumping record levels of atmospheric moisture into the storms running south.

You will need to Right-Click and open the image in a new tab.

As I said, a brainwashed dupe asked if there was a volcano under the Gulf. It is a diseased reflex among the dupes to see volcanoes everywhere. Volcanoes are why the West Antarctic ice sheet is sliding into the sea doncha know—and there was a Dubyne silly video on that. Retreating glaciers, the Totten etc on East Antarctica where there are no volcanoes were not mentioned, of course—these are not educational videos, these are brainwashing videos!

Anyway, the heat on the seas south and east of the US NE coast are clearly visible.

As the Jet Stream dip became more oriented toward the East Coast during March, storms that would ultimately blow up over the Atlantic at first got a big plug of moisture from the extra evaporation flowing off that warmer than normal Gulf. But it was over the Atlantic Ocean that the storms would really start to fire. There, ocean temperatures were ranging between 0.5 and as high as 9 C above normal over parts of the Gulf Stream.

Such very warm sea surfaces provide a lot of fuel in the form of moisture and related convection. And, in particular, we saw some rather amazing instances of convective lift during the recent March 2nd and 7th storms as they tapped that incredible Atlantic Ocean heat and moisture.


All this heat does not come from nowhere, especially not in the NH late winter to early spring! The heat comes from AGW, the AGW that blocks some infra red frequencies from escaping to earth.

The earth is a black body, not a perfect one but perfect black bodies just aren’t found in nature. Come on the night side of the planet and you can’t see it—the Earth does not emit visible visible light part of the EM spectrum. A black body that receives EM energy will emit IR and in so doing cool down. So when the atmosphere blocks some of the IR from leaving the atmosphere the planet inevitably warms up.

A fourth and even a fifth northeaster might be being formed. Comment to the blog mentioned above:

rhymeswithgoalie / March 14, 2018
This is reminiscent of the “conveyor belt” of major storms that hit the UK in early 2014 due to a different stalled configuration of the jet stream.

https://www.metoffice.gov.uk/climate/uk/interesting/2014-janwind


Reminiscent of a stalled pattern causing a five year drought in California.

West coast drought getting worse and moving to the central parts of the US. Wildfires—already this early in spring—breaking out is one sign.

the situation is now looking a bit worse for the Totten Glacier — an enormous sea-fronting slab of ice as big as France that if it melted in total would, by itself, raise sea levels by about 10-13 feet globally.

Previously thought to be more resilient to melt as a result of human-caused climate change and related fossil fuel burning, the Totten was once considered to be stable. However, over recent years, concerns were raised first when plumes of warm water were identified approaching the glacier’s base and later when it was confirmed that Totten was melting from below. Concerns that were heightened by new research identifying how winds associated with climate change were driving warmer waters closer and closer to the huge ice slab. . . .

After follow-on expeditions to Totten, scientists (over the past two years) discovered that the glacier’s floating underside was losing about 10 meters of thickness annually even as its seaward motion was speeding up. Now, new research has found that more of the Totten Glacier is floating upon this warming flood of ocean water than previously thought. According to Professor Paul Winberry, from Central Washington University, who spent the austral summer of 2018 with a Tasmania-funded team of scientists taking measurements of Totten:

“A hammer-generated seismic wave was used to ‘see’ through a couple of kilometres of ice. In some locations we thought were grounded, we detected the ocean below indicating that the glacier is in fact floating (emphasis added).”

Beneath Totten lies a large ridge upon which most of the glacier is grounded as it flows toward the sea. But penetrating this ridge are numerous gateways that, if melted through, provide sea water access to the glacier’s interior. And recent studies have found that a number of these gateways have been thawed open, allowing warming ocean waters access to sections of the glacier that are hundreds of miles inland.


https://robertscribbler.com/2018/03/20/the-great-totten-glacier-is-floating-on-more-warming-water-than-we-thought/

Not looking good, is it? One of these giant glaciers—Jacobshavn or Petermann on Greenland, Pine Island and/or Thwaites on West Antarctica or Totten on East Antarctica—give way sea levels will rise by many centimeters very quickly causing havoc in coastal cities everywhere.

$3Bn disasters in US in first three months of 2018, exacerbated by rising see levels that saw repeated flooding. A stuck pattern in the northern Jet Stream sent the storms on the same track to hit the NE US coast. These stuck patterns have seen other series of storms hit the same part of the Earth before.

This year has been “anything but ordinary” according to the latest data released by the National Oceanic and Atmospheric Administration (NOAA). In the first three months of 2018, the United States has seen three climate and weather disasters each resulting in more than $1 billion in damages.

Two of the four nor’easters to hit the central and eastern U.S. during a one month period resulted in record snowfall and more than a billion dollars in losses each. Millions were without power and hundreds of flights were grounded. Multiple deaths were reported across Connecticut, Maryland, Massachusetts, New York, Pennsylvania, Rhode Island, and Virginia. . . .

. . .scientists know that climate change is making nor’easters more powerful.

Nor’easters form when warm ocean air converges with cold terrestrial air. They are more powerful in the winter when the temperature difference is greatest. Climate change is making the temperature contrast even more pronounced, both by warming the Atlantic and by distorting the jet stream, allowing frigid Arctic air to reach further south. Rising temperatures in the Arctic are responsible for reshaping the jet stream.

Like with summertime hurricanes, winter nor’easters start in the ocean. And with warmer waters, these storms become more intense. According to Accuweather, this year’s series of devastating nor’easters spent more time forming over the ocean, giving them a chance to increase in strength by absorbing more of the warmer ocean temperatures.

This is an interesting article, which contributes to the jet stream and southern oscillation systems effect on climate. The slowing of the world oceans circulation, will lead to catastrophic events, the vast majority of humans won't be able to cope with as they have no fall back system to support them. As the southern oscillation system drives all world ocean currents, dramatic weather patterns will become more and more volatile.

https://www.washingtonpost.com/news/ene ... edirect=on

read a couple of predictions a few years ago which were rejected and removed from the web after just a few days, because they predicted we are close to 100 years out in the timing of climate change and what was predicted to happen next century was happening now and at much faster rates that thought. The conclusions reached, was by 2020, we would be be seeing uncontrollable weather events devastating areas humans congregate and that by 2030, we may see the demise of over 90% of the current human population. Cities increasingly are creating their own weather patterns, which are getting more devastating each time.

When you look at how everyone is approaching the future, not rocket science to see at the rate we are pushing climate change with our destructive ways of living, it's not beyond the realms of possibility. The number of people who have prepared for these dramatic changes, would by just a few millions worldwide, everyone else does nothing, but continue down the path to their extinction.

Weather will get more extreme and sea levels will keep rising.

But renewable energy prices keep falling and electric vehicle sales are ramping up so there are grounds for hope.

It is a pity that now we have Trumpy in Washington and Fizza, captive to the Nats and rabid right wing Libs, in power now.

Britain is going gangbusters with RE, building windfarms in the open seas where winds are stronger and more consistent. SA is going to drag its feet on RE under the Lib govt. It will take a major disaster—I predict flooding in the east coast of the US (and Bangladesh but nobody takes much notice of that)—but it could be anything.

We are rapidly running out of time!

Interesting article that, Dax. The Gulf Stream is something I have been concerned about for a while. I believe the so–called Little Ice Age (not really an ice age) may have been due to a slowdown in the Gulf Stream.

Notice how fishery stocks have moved north, staying in the temperature zone that suits them? There is a limit to that, 90°N! A rapid melt of Arctic sea ice and Greenland ice sheet would put a lot of fresh water into the North Atlantic, threatening the survival of some marine populations.

Agree with that, there are many other tings which are changing and will have a major impact upon us. At the present rate of commercial fishing, we are seeing a rapid decrease in sea life and when you add the huge changes in ocean current and warming. It will not be long before fish will become very scarce.

Used to fish a lot to feed myself, but over the last 10 years, most species in our area have disappeared, or are so small you can't take them. Now we are down to native black back salmon, which are now getting very small and the Atlantic salmon fish farms use massive nets to catch native salmon heading to and from breeding grounds and feed them to their fish farms. It takes 18kg of fish to provide 1kg of farmed salmon. So there is nothing illogical or sustainable in that insane approach. The government dropped catchable sizes for commercial farm operations, so they take all the fish and leave nothing for sea life. To cover the problem,have stocked my dams with trout and installed and aquaponics system, so am not a burden o the natural ocean world.

Expect when climate change reaches a certain point, along with over fishing of the seas, we will have many catastrophic events which decimate the ability for us to live and that's just a couple off years away. It will be the same on land, the accumulating effects of our over grazing, chemical poisoning land clearing and most importantly, over population of a very fragile environment. We may well see am almost instant collapse of the essential food chains and ecological stability.
