From the NIPCC report comes this study that suggests gloom and doom over pine forest growth suppression in the face of climate change is overwrought. The pine trees apparently have the tools within their genes to cope just fine.

Intraspecific Variation: Helping Species Survive Climate Change

Writing in Ecology and Evolution, Oney et al. (2013) note that species distribution modeling (SDM) is “an important tool to assess the impact of global environmental change.” However, they say that many species exhibit ecologically relevant intraspecific variation, but that “few studies have analyzed its relevance for species distribution modeling.” And, therefore, in an attempt to add to those few studies and enlarge upon their significance, the four researchers compared the results of three SDM techniques as applied to the highly variable lodgepole pine tree (Pinus contorta).

First, they employed a conventional approach called MaxEnt to model the tree as a single species, based on presence-absence observations. Second, they used MaxEnt to model each of the three most prevalent subspecies independently, after which they combined their projected distributions. And third, they used a universal growth transfer function (UTF) to incorporate intraspecific variation utilizing provenance trial tree growth data.

The end result of these various operations was that under future anticipated climatic conditions, the different projections of lodgepole pine habitat suitability significantly diverged. In particular, as they put it, “when the species’ intraspecific variability was acknowledged, the species was projected to better tolerate climatic change as related to suitable habitat without migration.”

In light of this finding, Oney et al. concluded that “models derived from within-species data produce different and better projections, and coincide with ecological theory,” leading them to also conclude that “intraspecific variation may buffer against adverse effects of climate change,” which ultimately implies that many climate-alarmist horror stories of various species extinctions occurring in response to projected global warming are likely enormously overstated, as in totally false.

Scientists found four different “generations” of above-ground remains with ages that dated 375, 5660, 9000 and 9550 years old.

And the Little Ice Age, for that matter.

so…..tell me again why plant nurseries sell these plants….to be planted in people’s yards….outside of their “native” habitat
>>>>>>>>>>>>>>>>>>>>.
So they can make money.
I found it amusing that the colored morning glories my neighbor up north so carefully planted grow wild here in the south. Southerners call it bindweed and hate them. I get rid of them by turning the goats loose on them or spraying them with a herbicide. (Large amounts are toxic to livestock due to alkaloids.)

LOL…yep
So they have this great ‘study’ to discover that these plants will grow outside of their natural habitat….when all they really had to do was take a drive through suburbia

Rather fancy way to show that Darwin was right.

Pinus contorta is a fascinating species but perhaps not a good subject for this type of study. P. contorta is widespread but actually has a highly discontinuous range with many isolated populations. Except at northern tree line and on the high elevation ash beds of eastern Oregon and the greater Yellowstone area , populations tend to be colonizers where other species cannot grow. Despite “intraspecific” variation, P. contorta somehow very effectively RESISTS speciation in its isolated populations. Can resistance to speciation be an adaptation to prevent isolated populations from adapting to temporary local conditions for the benefit of the species as a whole? P. contorta presents major challenges to the “selfish gene” theory.

“intraspecific variation”, local “gene pools” … Yep. Commonly observed here in the “Dry Tropics”.
Livistona australis, paperbarks, casuarinas sourced in the local area grow ok and will self-replicate if given a chance. Ostensibly the “same” sub-species sourced from nearby don’t do so well. On the other hand, we have the foxtail palm, originally found only in Cape Melville National Park and listed as endangered. They struggle if planted singly on traffic roundabouts and the like. Plant three together, they do better. Plant them in an artificial canyon eg between 3-storey buildings, they shoot up to the light.

Take a look around you. Are any humans you know exactly identical to one another?
Or are any animals you know exactly identical to one another?
Do you know of those amongst your friends and associates those who like and thrive in the cold and those who like and thrive in the heat?
The variations in genetic adaptability is universal throughout the planet’s bio -sphere.
So the variations in that genetic adaptability and the consequent natural selection from out of a species for those specimens that can adapt to a particular set of changing or changed natural circumstances is a universal attribute of life on this planet.
The cultists of global warming alarmism can in their ignorance and with their closed minds and rigid ideology, only imagine a fixed, rigid, inflexible, closed and limited in all aspects group of life forms on this planet. They are beyond imagining that any life forms might be able to adapt and adapt rapidly and yet that very immense specie’s adaptability, possibly the greatest adaptability of any life form on this planet, stares back at them every time they look in a mirror or look at another of the Homo sapien species.

Another such example here in Australia of the ability of what was assumed to be totally dead Australian outback River Gum Trees to re-shoot and start re-growing.
About a hundred or more years ago in more northern and very dry regions of inland South Australia [ the driest state in the driest continent ] a storm rain fed creek changed course to a new course some many kilometres distance away.
The great River Gums that line these outback creeks eventually died without the occasional storm fed run of the creek.
Recently the creek for reasons totally unknown, reverted back to it’s original course.
With the new runs of water a few of those old, dead trees suddenly started to throw out new shoots from what seemed totally dead and slowly rotting trunks and branches and started re-growing.
Nature is far, far more resilient and adaptable than the alarmists are ever capable of admitting or recognising.
Often due to the fact that recognising such natural resilience would seriously impact on their alarmist agenda based on creating fear of change and creating fear as as an object in itself.
The real problem in our modern society is that with over half the world’s population now living in cities of 100,000 population or more there is now a rapidly increasing lack of real down to earth knowledge and appreciation of just what Nature really is and just how tough and adaptable and resilient Nature outside of the highly rigid, artificial, mostly man made environment of the cities, actually is.
Our problem is not Nature’s adaptability or the way Nature acts and behaves and reacts.
It is in the mentally rigid picture of what Nature supposedly is and how Nature is to supposedly react to and it’s supposed inability to adapt that is being developed within the highly artificial man-made environment of the cities.
And that is a developing and major problem that politically and socially which will create immense problems for both Nature itself as attempts will be made to force natural changes and events into conforming with a rigid conformist ideology based around what Nature is supposed to look like and conform to according to the city based activists and ideologists.
When Nature refuses or fails to conform to this idealised vision then somebody must be at fault and scape goats will be sought and found. and they are most likely to come from the decreasing minorities and numbers in the rural regions of so many nations.
And immense and increasing problems for those who dwell outside of the cities and are the food producers and food providers and resource developers. will become a fact of life as the ignorance and complete out of touch with natural reality becomes a major attribute of the city based activists and ideologist who will increasingly try to enforce their idealised vision of Nature onto both Nature itself and onto those who live in, amongst and use Nature in their production and industrial pursuits.

In Georgia pine trees are the weeds of the tree family. You cannot get rid of them, the wind blows them over on peoples houses, and encroaching pine forests are taking over any piece of property that is not buzz-cut weekly.
So, the heck with pine trees. They are in no danger of disappearing. Indeed, they are like cockroaches. They seem to thrive everywhere.

Some species have adapted better by adapting the ability to adapt. Metadaptabilty!

ROM. Jim Steele,
When we lived in New England I had two wild AMERICAN Chestnuts in the back woods that managed to stay alive. One of them bloomed every year and had chestnuts. (I wish I had know at that time about the The American Chestnut Foundation.

“With the new runs of water a few of those old, dead trees suddenly started to throw out new shoots … .” (ROM at 4:43pm on 8/29/13)
That brought tears to my eyes. Even when all seems dead and finished, there is yet — hope.
There are so many metaphors for Life and Truth in creation. Amazing. Thank you for sharing that.
If trees can come back after being blown away by a volcano, they can survive anything the elements dish out:

Mt. St. Helens, 26 years later…
