Plants trapped under Iceland's icecaps
store a record of ancient temperatures

The Little Ice Age was caused by the cooling effect of massive volcanic eruptions, and sustained by changes in Arctic ice cover, scientists conclude.

An international research team studied ancient plants from Iceland and Canada, and sediments carried by glaciers.

They say a series of eruptions just before 1300 lowered Arctic temperatures enough for ice sheets to expand.

Writing in Geophysical Research Letters, they say this would have kept the Earth cool for centuries.

The exact definition of the Little Ice Age is disputed. While many studies suggest temperatures fell globally in the 1500s, others suggest the Arctic and sub-Arctic began cooling several centuries previously.

The global dip in temperatures was less than 1C, but parts of Europe cooled more, particularly in winter, with the River Thames in London iced thickly enough to be traversable on foot.

What caused it has been uncertain. The new study, led by Gifford Miller at the University of Colorado at Boulder, US, links back to a series of four explosive volcanic eruptions between about 1250 and 1300 in the tropics, which would have blasted huge clouds of sulphate particles into the upper atmosphere.

These tiny aerosol particles are known to cool the globe by reflecting solar energy back into space. 

The Little Ice Age saw an increase in
 cold winters in parts of Europe, but a
small global change

"This is the first time that anyone has clearly identified the specific onset of the cold times marking the start of the Little Ice Age," said Dr Miller.

"We have also provided an understandable climate feedback system that explains how this cold period could be sustained for a long period of time."

The scientists studied several sites in north-eastern Canada and in Iceland where small icecaps have expanded and contracted over the centuries.

When the ice spreads, plants underneath are killed and "entombed" in the ice. Carbon-dating can determine how long ago this happened.

So the plants provide a record of the icecaps' sizes at various times - and therefore, indirectly, of the local temperature.

An additional site at Hvitarvatn in Iceland yielded records of how much sediment was carried by a glacier in different decades, indicating changes in its thickness.

Putting these records together showed that cooling began fairly abruptly at some point between 1250 and 1300. Temperatures fell another notch between 1430 and 1455.

The first of these periods saw four large volcanic eruptions beginning in 1256, probably from the tropics sources, although the exact locations have not been determined.

The later period incorporated the major Kuwae eruption in Vanuatu.

Aerosols from volcanic eruptions usually cool the climate for just a few years.

When the researchers plugged in the sequence of eruptions into a computer model of climate, they found that the short but intense burst of cooling was enough to initiate growth of summer ice sheets around the Arctic Ocean, as well as glaciers.

The extra ice in turn reflected more solar radiation back into space, and weakened the Atlantic ocean circulation commonly known as the Gulf Stream.

"It's easy to calculate how much colder you could get with volcanoes; but that has no permanence, the skies soon clear," Dr Miller told BBC News.

"And it was climate modelling that showed how sea ice exports into the North Atlantic set up this self-sustaining feedback process, and that's how a perturbation of decades can result in a climate shift of centuries."

Analysis of the later phase of the Little Ice Age also suggests that changes in the Sun's output, particularly in the ultraviolet part of the spectrum, would also have contributed cooling.

20TH KRYON SUMMER LIGHT CONFERENCE, US (7), June 2-4, 2017 (Kryon Channelling by Lee Carroll) (Text version "The State of the Earth")

"....  A mini ice age is coming. "Kryon, isn't that doom for the planet?"  Many have seen the artist's rendering of major earth cities under ice and all of the other things that go very well with science fiction movies. That's simply a painting of someone's doom scenario, not reality based in the history of the cycle. If you want to know what a mini ice age is like, just flash back in history and study what took place in about 1650. That was a mini ice age. Due to the change in the Gulf Stream (the ocean), the river Thames froze in London. Dear ones, it was cold, but it did not doom the planet. That's a mini ice age.

That's what you're facing, and I'll say it again. If you live in a cold climate, heed this advice: It's going to get colder. Get off the grid! Within the next 15 years, find a way of producing electricity independently or in smaller groups. This can be done neighborhood-wide or separately in homes. You're going to need this, dear ones, because the grid as it exists right now all over the world is not prepared for this coming cold, and the grid will fail. That's not doom and gloom, that's just practical, commonly known information. Your electricity infrastructure is delicate, too delicate. Prepare for a cold spell that may last for a couple of decades. That's all it is. Technology is racing forward to allow this. Don't let your politics get in the way of your survival. ..."

"...  This is controversial. The planet can't just "change the water". It does it instead with a "reboot of life in the ocean" using the water cycle. Watch for evidence of this as it occurs, and then remember this channel. This weather cycle is to refresh the life in the ocean so that everyone on the planet will have needed food from the ocean. Gaia does this by itself, has done it before, and it does it for a reason - so it will not stagnate.

Dear ones, indeed, you have put compromising things into the air and the water, but it has not caused this cycle. We have said for a very long time, stop killing the environment! The reason? It's going to kill you, not Gaia. Gaia is spectacularly resilient and will survive anything you do. However, it is you who may not survive if you continue polluting. All this is starting to change with your awareness, and you're starting to see this and move with it. But Humans are not causing the current weather shift. This will be known eventually.

What is happening has happened before, and it's almost like a reboot for the oceans and it carries a lot of dichotomous events. You're going to see reports of a dying ocean, but at the same time you're going to see unusual reports of too many fish and other sea life in places that were supposed to have a decline. You're going to see the life cycle of the ocean itself start to change and reboot.

The chief player in this renewal is a place you would not expect: Antarctica. I want you to watch for magic in Antarctica. It has always been the core of the refreshing of microbes and other kinds of life in your oceans and it's especially active during these mini ice ages. The process will cause currents under the sea to be filled with new life, delivering it to both hemispheres almost like an under-sea conveyor belt. ..."

“… 4 - Energy (again)

The natural resources of the planet are finite and will not support the continuation of what you've been doing. We've been saying this for a decade. Watch for increased science and increased funding for alternate ways of creating electricity (finally). Watch for the very companies who have the most to lose being the ones who fund it. It is the beginning of a full realization that a change of thinking is at hand. You can take things from Gaia that are energy, instead of physical resources. We speak yet; again about geothermal, about tidal, about wind. Again, we plead with you not to over-engineer this. For one of the things that Human Beings do in a technological age is to over-engineer simple things. Look at nuclear - the most over-engineered and expensive steam engine in existence!

Your current ideas of capturing energy from tidal and wave motion don't have to be technical marvels. Think paddle wheel on a pier with waves, which will create energy in both directions [waves coming and going] tied to a generator that can power dozens of neighborhoods, not full cities. Think simple and decentralize the idea of utilities. The same goes for wind and geothermal. Think of utilities for groups of homes in a cluster. You won't have a grid failure if there is no grid. This is the way of the future, and you'll be more inclined to have it sooner than later if you do this, and it won't cost as much…

Water

We've told you that one of the greatest natural resources of the planet, which is going to shift and change and be mysterious to you, is fresh water. It's going to be the next gold, dear ones. So, we have also given you some hints and examples and again we plead: Even before the potentials of running out of it, learn how to desalinate water in real time without heat. It's there, it's doable, and some already have it in the lab. This will create inexpensive fresh water for the planet. 

There is a change of attitude that is starting to occur. Slowly you're starting to see it and the only thing getting in the way of it are those companies with the big money who currently have the old system. That's starting to change as well. For the big money always wants to invest in what it knows is coming next, but it wants to create what is coming next within the framework of what it has "on the shelf." What is on the shelf is oil, coal, dams, and non-renewable resource usage. It hasn't changed much in the last 100 years, has it? Now you will see a change of free choice. You're going to see decisions made in the boardrooms that would have curled the toes of those two generations ago. Now "the worst thing they could do" might become "the best thing they could do." That, dear ones, is a change of free choice concept. When the thinkers of tomorrow see options that were never options before, that is a shift. That was number four.”

THE RELATIONSHIP TO GAIA - April 2010 (Kryon channelled by Lee Carroll)

GLOBAL WARMING – NOT LONG TERM (WATER CYCLE)

New Mini Ice Age

"The weather you have today, and all the alarming attributes of it, is a scenario of what was scheduled to happen on Earth anyway. I review again that the weather changes you are seeing prophesied by myself, 21 years ago, are not a surprise. The changes are not caused by the pollutants you put in the air. You call it global warming and that's a nice phrase, and perhaps that will get you to put less pollutants in the air – a very good thing. But what you are seeing in the weather shift today was not caused by Humans putting things into the air. It would have happened anyway in about 300 years."

"We've called this process the water cycle, since it's all about water, not about air. The water is the predominant attribute of Gaia and of the weather cycle you're seeing. More predominant is the temperature of it. The cycle is ice to water and water to ice, and has been repeated on this planet over and over and over. It is not new. It is not exceptional. It is not frightening. But it's a cycle that modern humanity has not seen before, and it's a long cycle that is beyond the life span of a Human Being. Therefore, it tends to be overlooked or not seen at all !"

"In the days of the Lemurians, the water level of the Pacific Ocean was almost 400 feet lower, and that's only 50,000 years ago. [Kryon invites science to check this out – the water level at that time.] That was a water cycle working, and the reason it was lower was due to so much of the water being stored as ice. Today you're going through another water cycle that will eventually lead to cooling. The last one was in the 1400s."

"Science sees that at about 1650. As mentioned, they are so slow there is no remembrance that a Human has of them except in past writings and in the rings of the trees. The time span of the changes is so great that environmental record keeping does not exist in the form that it does today. But you can still look at the rings of the trees and at the striations of the rocks and can generally figure out that a few hundred years ago, you had a mini-ice age. Now you're going to have another one."  Read more .....(THE RELATIONSHIP TO GAIA - April 2010 (Kryon Channeling))
