Who would have thought – apparently a few degrees of global warming won’t make the cold North Eastern states of America, and Eastern Canada, into blazing hot uninhabitable deserts.

Northeastern North America as a potential refugium for boreal forests in a warming climate

A future for boreal forests

Conservation under climate change presents the challenge of predicting where will be suitable for particular organisms and ecological communities in the future. D’Orangeville et al. assess the probable future range for boreal forests in eastern North America, which are expected to be subject to large temperature increases in their natural range. Using tree-ring data from many thousands of forest stands, they delineate the geographical extent of the region where tree growth responds favorably to higher temperatures and where the forest should persist at least until 2070.


High precipitation in boreal northeastern North America could help forests withstand the expected temperature-driven increase in evaporative demand, but definitive evidence is lacking. Using a network of tree-ring collections from 16,450 stands across 583,000 km2 of boreal forests in Québec, Canada, we observe a latitudinal shift in the correlation of black spruce growth with temperature and reduced precipitation, from negative south of 49°N to largely positive to the north of that latitude. Our results suggest that the positive effect of a warmer climate on growth rates and growing season length north of 49°N outweighs the potential negative effect of lower water availability. Unlike the central and western portions of the continent’s boreal forest, northeastern North America may act as a climatic refugium in a warmer climate.

The press release;

The Most Hopeful Place On Earth For Climate Change

Eastern Canada’s black spruce forests are one of the largest untamed wilderness areas on Earth. And in refreshingly optimistic news, parts of this ecosystem are expected to flourish in a warmer world, creating a refuge for species escaping drought-stricken regions to the south and west.

That’s the conclusion of a sweeping new analysis of black spruce trees across 225,000 square miles of forest in Canada’s Quebec province. The research, published today in Science, offers clues as to how this vast ecosystem will fare under human-caused climate change. While the boreal forest’s southern and western regions are likely to struggle with drought in a hotter future, parts of eastern Canada north of the 49th parallel could see a net benefit as the growing season lengthens.

“Climactically speaking, this looks like a system that can take what we think is going to happen in the next 20 or 30 years,” Harvard ecologist and study co-author Neil Pederson told Gizmodo. “It’s hope. It’s a bright spot.”

The boreal forests of North America and Eurasia are some of the most pristine wildlands on the planet. In addition to providing habitat for dozens of charismatic animals, from moose and caribou to foxes and migratory birds, they’re a massive carbon sink, locking away hundreds of billions of tons of organic matter in their soils. That means these forests are not only a sanctuary for biodiversity, but an important regulator of global climate.

“The trees are telling us that it might not be so bad.”

Since we evolved to suit the sub-tropical forests and plains of Africa surely we should be grateful that through our own efforts (supposedly) we are returning to a more ‘natural’ temperature for humans? Let’s get rid of these un-natural cold temperatures we have been having for decades and return to our proper climate! LOL

I just arrived back from a weekend at the Oregon
Coast. The place we were at was loaded with driftwood; tons of huge trees down on the beaches. I wondered if it was permissible to cut them up for firewood or other useful purposes.
I guess it is, because just before leaving, a walk to a different part of the beach found the stump of a quite large conifer of some sort, that had clearly been hacked at as the stump was cut clean across, with about a 5 ft. diameter. Although the end was just plain saw cut, the tree rings, were very prominent, and I might have been able to count them on the spot.
But I took to good high res photos of the stump surface, in bright sunlight, so I will be able to use those photographs, to tell the temperature, the wind direction, the wind speed, the rainfall amount, the direction of the rainfall. All kinds of stuff I can read off that stump just like Mikey can.
I have even seen claims that you can actually tell the age of that tree from those rings. Well I guess only the living age of the tree. Maybe I can figure out how long it has been dead too.
Remember that a tree stump is a two dimensional portrait of a three dimensional object. And if it was a living tree, and you did a core drill, instead of a beheading, you will get a one dimensional sample of that three dimensional object.
There is one glitch to this. I think I mentioned that this was beach driftwood, which means it could have come from Alaska or Canada, or even from the local Oregon or Washington (even California) forests.
So I have no idea which way was north on this tree when it was a tree, instead of a stump.
Well not to worry, the ring thickness goes through at least four complete cycles, from paper thin rings, to rings almost a half inch thick, as you go around the stump.
So this tree should be amine of information just like the Yamal Charlie Brown Christmas tree, but that information will all be about some unknown place.
There’s a lot of insectile boring in about the middle of the ring count, but at the moment, I can’t tell if this was insect or bird activity way back when this was the surface of the trunk, or whether this is post mortem insectivation.
Well If I can get a look to see which is the best picture, I will try to get it to Anthony to sub for the Yamal tree.
Quite a few years back the was an article in Nat Geo, about the Bristlecone pines in the
White Mountains of California.
There’s a picture of a stump still engrounded, which was left by a researcher. He had just got a Masters degree, in botany or bology or something, and he wanted to find out how old bristle cone pines were, so being of sound mind and MS enshingled, he found what looked loke an old tree, so he cut it down with a say, and cut a slice off it, to take back to his lab. Well to his amazement, he found that this tree was around 5,000 years old, so he excitedly showed his handiwork to his peers.
In horror, they asked him if he had ever learned about core drilling, while mastering his Botanicals.
Well somewhat red of face he hied back to the white mountains, now with a nice shiny new core drill, and he started coring and boring Bristlecone pines till the cows came home.
He found lots of old BC trees up there.
He never ever found another one that came within 500 years as old as the one that now sits detrunked out there in the White Mountains.
This MS rocket scientist cut down the oldest known Bristle Cone pine tree, just by being dumber than a box of pine cones.

Once again, they’ve omitted any discussion of the most important effect of increased atmospheric CO2.
Probably (close to a certainty) because that is a joke, and a clear “pink unicorn”.
It is pretty clear that greenery in this planet increases only during a warming trend.
The only way to consider the CO2 as with a significant potential effect on greenery is only if CO2 causes warming and therefore causing AGW.
For the last 150 years there has being an increase of ~120 ppm but still Sahara is a dry desert place and many other places like Gobi show that desertification is still in full force .
From Wikipedia:
“The Gobi Desert is expanding at an alarming rate, in a process known as desertification. The expansion is particularly rapid on the southern edge into China, which has seen 3,600 km2 (1,390 sq mi) of grassland overtaken every year by the Gobi Desert. Dust storms, which used to occur regularly in China, have increased in frequency in the past 20 years, mainly due to desertification. They have caused further damage to China’s agriculture economy.”
Only looking in short term (from the short-term lookingglass or crystal-ball) with no any regard for long term can lead to conclusions like CO2 is causing increase of greening or increase of biomass, or that there actually is any significant greening in overall actually happening.
Looking carefully it shows that in both long term and short term it is humidity and precipitations that are the main cause of the variation in the biomass aka greenery.
There is places in Africa that clearly show that in short term. there is places there that in one season are lash watery and swampy and in the next season turn in to dry bone places, only due to humidity and nothing to do with CO2 emissions or concentrations.
In long term also all data at the best show that this planet has being going through a desertification trend during the last ~7k years of the cooling trend and still keeping on it.
There no any sign of it been halted even temporarily or stooped as supposed to have being if AGW real and happening.
Another thing, variation of ppm(s) in CO2 concentrations have no any significant effect in plants because the share of the biomass in the “river” of CO2 flux is insignificant, especially in a case of very short residence time of CO2 in atmosphere.
The plants do not even “feel” the variation of ppm(s) but do feel greatly the variation of humidity to a real point of even starvation.
There is a parallel relation and clear correlation between desertification and glaciation, in a cooling trend.
Both have a reducing impact on the biomass and greenery in overall, which makes the claimed effect and impact of CO2 concentration variation in to the biomass a joke.
Unless CO2 causes climate change, CO2 can not cause increase or decrease of the biomass, by causing blooming or starvation of it
And the reason why the AGW “science” is not very keen on it is because is very easy debunked and in return showing clearly that AGW is not happening.
From this angle is not hard to see why so much weight in short term and its terminology of “droughts” and “floods” with no any regard whatsoever of long term and it’s associated terminology of desertification.

Consider that CO2 levels have increased by 40%. Long running “FACE” (Full Access Carbon Enrichment) experiments suggest that a very conservative estimate is that this has increased the planetary biosphere productivity by at least 10%.
Put this in purely human terms. Since there are 7 billion people on the earth, 700 million are now being fed by productivity increases due to CO2 fertilization.

Since they use tree ring measurements it seems they commited the very same two “mistakes” Mann did. First, as you said, they assinged the cause of all the growth to temperature increase and none to CO2 fertilization, and second, they perceived the increase of tree ring thickness as a bad thing, when it is actually a very good thing. Trees are growing faster, That is the important fact. It is not about Gaia, Gaia is a mental construct, it is not real, it is not alive. Trees are real, they are alive, and they are growing faster. If they don´t see that, they are not ecologist or environmentalists.

Tree rings are all about how much rain, how few insects and other issues affect trees. It has very little to do with mere temperature. Every 20 years we get bug infestations where they eat everything and having lived through one such, the sound of insect pests crunching the leaves is loud! Birds get super fat eating these bugs, too.
From day one, tree experts have been very upset about ‘climate experts’ misusing tree ring data.

Reply to  urederra
June 17, 2016 9:42 am

Trees, like just about all living things have an optimum temperature. Above that, or below that, then growth slows. If trees are above their optimum temperature, a decrease in temperature would cause an increase in tree ring size.
So even if they could prove with scientific certainty, that none of the couple of dozen other things that affect tree growth have changed, they still could not say with certainty that an increase in ring size meant the climate got warmer.

The following is a photo of a cross-sectional slice of a 60+- year old tree as denoted by the number of “tree rings” or yearly “growth rings” …… that vary in width from quite wide or thick to quite narrow or skinny ……. and you can pretty much bet that no two (2) of those “rings” are exactly the same width.
And the only thing those “tree rings” can tell you is that the years of the wide width rings were good growing years ……. and the years of the narrow width rings were poor growing years.
And you can guess why it was a good growing year ….. but there is really nothing about those “narrow growth rings” that will tell you why it was a poor growing year.

Somehow, I seriously doubt that the tree are going to notice even a 2°C increase. Their annual temperature ranges are far more than a few degrees of tepid temperatures.

In the north, black spruce sites are commonly underlain by permafrost (perennially frozen soils). Black spruce seems to be the tree species best adapted to growing on permafrost soils because of its shallow rooting habit.”

I don’t doubt it (2C being noticed) at all. There is always a limit where a tree can grow. Add 2C and the treeline will start moving. How bad is that is a totally different question. IMO climatic effects are so badly swamped with other factors, like random fluctuation that you mentioned, not attributable to climatic shift, that I really have difficulties to panic. My countrymen doing forestry seem to agree with me and those who do not agree are people doing neat indoor activities with computers.

Plants usually die when conditions are too harsh. Plants have two principal methods to adapt. First, they produce seeds that are spread by the species-specific manner, by wind, or using for example birds to spread them, so some of the seeds will fall into better suited place for the species, while of course some will fall in a place badly suited. Since conditions vary at very short spatial and temporal distances, the seeds don’t need to go so far in a generation.
The second way to adapt is the genetic variation. Many plant species have a polyploid set of chromosomes, so they have plenty on alleles that may express for the same locus. The ability to create genetically variable seeds is one of the primary factors that keep species vigorous. In woody plants, this of course takes time, usually from 10 to 40 years per generation, but on the other hand, plants create huge amounts of seeds to make sure each and every useful combination keeps appearing to the position seeds end up.
Animals, on the other hand, have extensions that we call legs, which they use to move around. Many animal species can move miles in a generation, even when the legs are pretty small. Some of the animals have specialised legs called wings, and they are capable of moving thousands of miles twice a year. So your suggestion about air is correct. There is also a documented case of domesticated pests called rabbits using local train to get shelter and move around, so your suggestion about rails is also right to some extent. Insects go simply by the wind.
However, if you are concerned about some mice living on island being incapable to escape, we might want to found a Rescue Patrol. I’m sure your good work would not go unnoticed.

Now I liked your comment about “genetically variable seeds keeping species vigorous” simply because it reminded me of the uniqueness of Apple and Peach trees, most any Apple or Peach tree.
One might say they are both “genetically vigorous”, in the same way as are humans, because one never knows, or can even predict, ….. what a fertilized “seed” is going to produce until after it is sprouted, birthed and/or “bears fruit”.
And for those not learned on the subject, ….. if you want two or more of the same “type” of apple or peach trees …. you have to graft them. If you plant a seed from an apple produced by your favorite apple tree, ….. you will get a different “type” of apple tree everytime.

Indeed, it is enough to drive one to tears. I’m also thinking this was another study they could have done without.

June 17, 2016 1:43 am

Temperature going up inside the leaf used to mean (for the previous 23 million years when CO2 was below 400 ppm outside them) that O2 in solution didn’t go down the same rate CO2 in solution would. Rubisco enzyme would then increasingly engage with O2 , which meant it would “take on/breathe” oxygen in a dynamic termed photo-respiration.
Yet elevated CO2 in C3 plants, like study cited tree, has a side effect of raising Rubisco handling of CO2; which correlates as less O2 interacting with Rubisco. Plants have a pathway that serves to clear up potential reactive oxygen that is a natural byproduct of photosynthesis as light rises in the day.
MAP (Mahler ascorbate peroxidase) pathway results in electrons
shunted to O2 by a chloroplast subsystem (PS1), which could otherwise become super-oxide (reactive oxygen species), be made into H2O (instead of reactive oxygen). Trees are well adapted to long periods of dry roots; they deal with heat impacting evaporation of internal water.
Survival of the leaf is tied in to limiting the reactive oxygen potential damage to leaf cells; which is why mention MAP
neutralizes light’s electron surfeit & hydrates the cells. In addition
this trees’ leaves have substantial structural design/composition to minimize water loss from their leaf.
As for the claim this forest is better at prospering than plants elsewhere, should this have some validity, I have a further comment on that. Ideally tomorrow can find time to develop it.

June 17, 2016 4:00 am

I own a fair amount of forest and every 20 years, harvest it. I live on a mountain and I am amazed at how fast the trees are growing now compared to say, 1978. It is green everywhere! The entire Northeast, after our government did free trade and killed off a great deal of the farming here after a flood of farm products poured in mainly from the subsidized EU farmers, nearly all the farms up here shut down and instantly, the forests took over.
Now, our community makes its money from processing oak and other hardwoods which the world wants because it is very good wood and I am finally making money again. Trees love CO2. No longer starving.

Alaskan records indicate warming since at least 1800. Did we do that?

Given the fact that for the last 100 years or so, we have been fighting all forest fires and have finally wised up and stopped that nonsense, it’s hardly surprising that forest fires are up. The forests have 100 years of burning to catch up on.
The fact that a few tenths of a degree in warming has caused boreal forests to modify their boundaries is hardly surprising.

Radiocarbon-dated macrofossils are used to document Holocene treeline history across northern Russia (including Siberia). Boreal forest development in this region commenced by 10,000 yr B.P. Over most of Russia, forest advanced to or near the current arctic coastline between 9000 and 7000 yr B.P. and retreated to its present position by between 4000 and 3000 yr B.P.
Forest establishment and retreat was roughly synchronous across most of northern Russia. Treeline advance on the Kola Peninsula, however, appears to have occurred later than in other regions. During the period of maximum forest extension, the mean July temperatures along the northern coastline of Russia may have been 2.5° to 7.0°C warmer than modern.
The development of forest and expansion of treeline likely reflects a number of complimentary environmental conditions, including heightened summer insolation, the demise of Eurasian ice sheets, reduced sea-ice cover, greater continentality with eustatically lower sea level, and extreme Arctic penetration of warm North Atlantic waters. The late Holocene retreat of Eurasian treeline coincides with declining summer insolation, cooling arctic waters, and neoglaciation.

And also this:
Griff quoted, to wit:

” (researchers) found that fire frequency in a 2,000-kilometer swath of the Yukon Flats is higher today than at any time in the last 10,000 years

Griff, educate yourself on the ABSOLUTE necessity of forest fires in many locales of North America, including the Yukon and other areas in Alaska and British Columbia.
To wit:

Cones [of the Lodgepole Pine [Pinus contorta,]
The 3–7 CM cones often need exposure to high Temperatures (such as from forest fires) in order to open and release their seeds, though in subsp. murrayana they open as soon as they are mature. The variation in their serotiny has been correlated with wildfires and mountain pine beetle attacks.[25] The cones have prickles on the scales.

From the CBC- so commie B.S. until proved otherwise
It says that worldwide the boreal forest is “mostly intact”
The rest is all could, might and mindless speculation.

Thanks for the good news on tree growth. My compost works best with leaves. Now that the rain has stop for awhile my garden is coming alive. The leaves on my grape vines have restarted sprouting, as well as the other vegetation. Lost cucumbers and the actual grapes themselves from too much rain.
Now the roots are driving deeper, this will increase nutrient uptake to the plants and tree leaves for a better compost for winter crop.,+Santa+Fe,+TX+77517/@29.4048942,-95.1152732,203m/data=!3m2!1e3!4b1!4m5!3m4!1s0x8640816457822d97:0xa20960b9b9e5626d!8m2!3d29.404893!4d-95.114699

Spring was quite late this year and now, just this last week, we have active sunspot activity plus good old CO2 and my trees are growing at a mad, mad rate and are very pleased with all this. And the wild turkey chicks have hatched and are marching behind mom and dad while eating insects…and the other wild birds are outside my window, quarreling over the bird feeders.

The biggest threat to those forests pictured in the post is the spruce budworm infestation. And once again, it is a cyclical phenomenon, though they will try to link it to global warming.
“Scientists are investigating how climate change may be influencing a spruce budworm outbreak in Quebec’s forests.
An area the size of Belgium on Quebec’s North Shore is now affected by the highly destructive insect, which feeds on the young needles of white, red and black spruce and balsam fir trees.
Spruce budworm populations go through cyclical fluctuations and reach outbreak proportions once every 30 to 40 years, leading to widespread defoliation and massive losses for the forest industry.
The spruce budworm population in Quebec has been steadily increasing since 2006, and more than 3.2-million hectares of forest have been affected.
The federal government has invested $6 million to control the outbreak in Quebec.” CBC News

So let me get this straight. The unspoken message is to prepare to go North? Now what could go wrong with that idea?????

Henry, look at the 60-66 year cycle and you will find that the atmospheric cycle that caused it has just past. The currents that drive the gulf up through Texas started to dissipate in 2006. Thus the 7-11 year cycle has come to an end. Look at the early 40’s for the up coming weather. I have begun looking at the military information to try and get more on what the weather was like after the dust bowl.

I disagree. The Gleisberg is more persistent.
look at tables II and III
clearly there is a 80-100 weather cycle, that is determined by the [type of] energy-out from the sun.

Henry, Thank you. This is great information. But with all cycles they will fluctuate. I believe that the same cycle in the 1930’s weather pattern has just pasted. In the fact that here in Galveston county Texas I spent 4-6 hours a day during 07 through 12 or 13 during many periods throughout the spring and summer seasons trying to keep plants watered. The rain patterns prior have seemed to come back with a vengeance. I will keep reading to improve my knowledge.
Thank you for all you do.

If they looked at old tree rings, did they happen to notice the preserved tree stumps now reappearing from under the ice in Alaska and northern Canada? I wonder what their explanation is for that, in this “warmest ever” world.

I am convinced that rainfall (water) is the dominant factor that would influence tree growth.
You can believe what you want, but your story of great differences between trees standing 100 yards apart is hard to accept.
if you want to learn about solar cycles, there is no easy way.
It is a long way to Tipperary…

Reply to  HenryP
June 18, 2016 10:05 am

@ HenryP
In many locales, rainfall is a dominant factor, …… but is really unimportant in other locales.
Tree growth does not depend on any rainfall ….. iffen those trees are growing at a Desert Oasis, …. or growing on the “flatland” of a river channel with their roots in the “water table” ….. or growing on the banks of a lake, river, stream or pond,

You can believe what you want, but your story of great differences between trees standing 100 yards apart is hard to accept.

HenryP, I can only offer you “the FACTS”, …. it’s your option to believe or not believe them to be true.
A tree out in “the open” will grow faster than multiple trees in a group.
Mineral nutrients in the soil can be different 50 to 100 yards apart.
Soil moisture decreases as elevation increases, …. thus a tree growing 50 to 100 yards up on top or on the side of a hill DO NOT HAVE ACCESS to as much ground moisture as do the trees growing down-slope or at the bottom of the hill.
Trees that are growing in “the shade” of hills, mountains, buildings or the canopy of other trees …. for a portion of every day … do not grow as fast as a similar tree that is not “shaded”. The morning Sunshine never strikes the trees growing on the Western side of a hill until the afternoon. And the trees growing on the Eastern side of the hill gets no direct Sunshine during the afternoon.
And HenryP, just what makes you think I need to “learn about solar cycles”? Or was that just an “ad lib” for lack of something knowledgeable to say?

@ HenryP
I am not sure what you are asking me to tell you.
Anyway, my learned opinion (given my AB in Biological Science which included Botany) is, …. the use of “growth rings” as proxy data for determining past weather or climate conditions of hundreds to thousands of years BP (Before Present) is little more than an act of futility on the part of the researcher.
HenryP, ‘click’ this hyperlink and read about the Science of “growth ring” dating, ….. Dendrochronology
But don’t get too excited when you read where it states …… “used to determine certain aspects of past ecologies (most prominently climate)” ….. simply because 1 or 2 or a few ancient timbers, that no one knows where they were timbered at, makes for a highly questionable “climate guessing” game.

Dear Sam
I appreciate your comments and they do make great sense to me.
I know a lot about chemistry and about stats.
Your comments tell me exactly what the problem is –
which I faced as well when putting together my own graphs of global minima and maxima:
you have to design a very specific sampling procedure if you want to make the tree rings tell you something important.
perhaps, like me, it would help if you balanced your (tree) samples to zero latitude and a certain altitude and look only at the [average] rate of changes in size per annum?
Unfortunately that is already 3 parameters, which is one too many.

June 19, 2016 5:59 am

perhaps to further clarify:
my sample of weather stations here:
is balanced on latitude (to zero)
I figured longitude would not matter as long as we looked at the change per annum
I remember having an argument with Anthony about the validity of the graph as altitude was excluded as a factor.
I think in my case, altitude does not matter as long as we look at the rate of change, which is an absolute figure.
