Jeff, I understand what you are saying but I tend to agree with Malcolm  but 
take that with a grain of salt as I am no PR or media specialist.

I think that your examples of a rancher, preserve manager, and municipality 
show 
that there is a misunderstanding by scientists as to the relevant time and 
spatial scales. I'm talking about ecosystems that span 5 states not ranches. 
The 
fact is that if I drop a 15 km pixel of the Regional Climate Model over either 
the Bighorn Mountains or the Powder River Basin of Wyoming that I still can't 
come up with specific predictions. Below is an example that is relevant today 
with the record hot temperatures and lack of precipitation over the 
northwestern 
prairie. Note that the regional models for western North Dakota, South Dakota 
and Nebraska 50 years out at the high CO2 emissions scenario predict about the 
same average temperatures and precipitation for the April to June wet season 
with a slight shift to more precipitation in April.

If we look at the entire northwestern prairie and want to make a prediction 
about how climate change will affect its wet season in 50 years the first 
problem we face is that the extreme western margin is dominated by winter 
precipitation regimes while the eastern from North Dakota south to Nebraska is 
dominated by an April-June wet season.

Let's just look at the eastern margin. Winter is the dry season. As the 
mid-latitude jet stream starts to move north in April it is still far enough 
south that Rossby waves, the kinks in the jet stream that move downstream, dip 
every week or so and are positioned almost north to south along the eastern 
side 
of the Rockies. When the kinks tighten enough they pinch off and create low 
pressure systems that spiral downwards from 40,000 feet to 10,000 feet or so. 
The high elevation of the Rockies creates a northward flowing lower elevation 
jet at about 12,000 feet that streams moisture from the Gulf of Mexico into the 
heartland. When the timing of the low elevation jet and the cut off low are 
right the moisture in the low jet gets a free ride upward and creates a 
regional 
precipitation pattern as the low is occluded. This happens periodically during 
the wet season and requires a high pressure system just west of the Rockies to 
work. There is a net increase of moisture from the Gulf of Mexico into the 
eastern Plains region. As the polar high shifts further northward taking the 
jet 
stream with it this pattern is eliminated and precipitation in July and August 
shits to local convective storms. Other models of climate change taking a 
functional approach state thatthe velocity of the jet stream in the region will 
grow slower and the kinks will deepen. This will cause both the wet spells and 
dry spells during the wet season to become longer - eg increased variablity but 
the same amount of precipitation.

The climate literature is just about as dense as the climate change literature 
but it is fascinating because you can see it happen in real time on weather 
maps 
and satellite imagery. The problem I have is that all I get from the Regional 
Climate model is average precipitation from April through June. Now I couple 
that with the other models that tell me that the dry periods and wet period 
will 
become longer. Then I add on our current understanding of the drivers of 
current 
climate. Finally, I try to interpret how an organism or a vegetation type will 
respond to all of this. 


If we are sitting in a bar and having a couple IPAs I will say something like 
HTFSIK what will happen. That is most definitely not what I read in reports and 
the literature. Don't get me started on the cottage industry of climate 
envelope 
models coupled with MAXENT species distributions.

Best,

John

Hey John – Great points. I have two main thoughts:
 
1) There is a great deal of uncertainty about exactly how climate change will 
manifest itself, especially at the local scales that your clients, etc. are 
considering.  Our science isn’t often precise enough to be able to offer 
specific prescriptions for a rancher, a preserve manager, or a municipality as 
to how their operations should take action for the future. However, what 
Monckton, Senator Inhofe, etc. offer is a very  anti-scientific denial of the 
large-scale research about the connections between carbon emissions and climate 
change. I didn’t go into this in our EOS piece, but I made the specific point 
at 
our counter-presentation that we have a great deal to discuss as  to HOW 
society 
should confront climate change – Cap&Trade, Carbon tax, mitigation, etc. But 
such a discussion must begin with an acceptance of the understood science. 

 
2) Related to the point above, Monckton et al are a separate category from the 
general public who does have difficulty filtering out the conflicting sides of  
the “debate”. I specifically referred to the public being “doubtful” or 
“skeptical”; but to say that Monckton is doing anything but cynically denying 
reality for the purpose of his own political agenda is naive. Monckton trades 
in 
the currency of attacking  the credibility of scientists – and the public’s 
distrust of science or confusion about climate change is a function of his 
ability to command attention.

Hi Jeff,

I don't want to get into the whole climate change Denier issue directly but I 
will add my observations in advising governmental clients on the use of the 
various types of climate models (Global, Regional, various types of 
statistically down-scaled) for their  landscape level planning efforts. I also 
have heard an earful from friends at various California state agencies 
regarding 
their opinions.

What the agencies want is clear direction on how to plan for climate change. 
Other than the obvious general tactics such as larger preserves are generally 
better and connectivity is generally better there is little that the models can 
do to provide the level  of information that the agencies expect. For on the 
ground planning the resolution of the Global models is too coarse (60-100 km 
pixels) and they don't really do precipitation so you just have a temperature 
increase. The Global models also don't take into  effect important features 
such 
as mountain ranges. The Regional models are also fairly coarse resolution (15 
km 
pixels) but do incorporate surface features. One problem with regional models 
are that they are too coarse for looking at local effects which the  agencies 
want but they do pick up regional patterns. Another problem of usage is that 
the 
output of the regional models is not intelligently utilized. Generally, the 
data 
are almost always reported as the average temp or precipitation per day over a 
3 
month  calendar period which is not biologically relevant. Even if you were to 
do the intelligent thing and lump the data by local seasons you still have to 
know enough about how the climate actually works in the region to interpret the 
data. Sure, most models predict  more variable climate but exactly what does 
that mean for a wolverine in the middle Rockies for example? PRISM data are now 
being commonly used to model climate data at 800 m resolution but projecting it 
out to 50 years not to mention 100 gives you false precision  even if the data 
are accurate and there are a some known issues with the data. Finally, you have 
to have baseline data to compare the model data to and that data is also 
modeled.

So how does this relate to the public's perception of climate change? The 
subject of climate change is a very complex thing with lots of almost 
unintelligible (to me at least, and my training is in plant physiology and 
ecophysiology) moving parts. There is  a huge amount of data coming in from 
field research concerning the aparent responses of organisms and ecosystems, 
there are a huge number of inconsistent climate models that are being misused 
without any semblance of protest by the scientists that created  them that I 
have been able to detect, and finally, there is a huge cottage industry of 
climate change adaptation in which regulated entities are connected with 
sources 
of funding by middlemen.

If I get confused and overloaded by all of this what can reasonably be expected 
of a lay public? Ultimately this should not be framed as believers and deniers 
as science is not a belief system - yes there is a huge field of the philosophy 
of science which shows  that this is not exactly the case but that is another 
huge and complex subject. Given my personal confusion and information overload, 
I resort to what I hope are accurate basics. We are doing things to the planet 
that are altering its heat balance rapidly  and irreversibly for 500 years or 
so 
at the minimum. We appear to be observing a number of phenomena ranging from 
organisms to climate that support the altered climate hypothesis.

The problem is that I have to "believe" in the competence and credibility of 
the 
scientists and their interpretation of the data and that is where I feel 
uneasy. 
Given what I perceive in my role as a non-academic and non-research scientist 
who tries to understand  and use the data, there is a significant lack of open 
peer evaluation of the data and that gives me pause as does the the scientist 
who won't speak up when his data and conclusions are over-interpreted by users.

By focusing on the "Deniers" you may be winning a battle but losing the war.

Best,

John Gerlach

Hello Ecolog - In March, one of the leading anti-minds of the Climate Deniers 
movement, Christopher Monckton, visited Union College. EOS, AGU's Newspaper, 
just published a Forum article describing our experience and that at our 
neighbor RPI. Subscription is  required - http://www.agu.org/pubs/eos/ - but 
I've pasted the first two paragraphs below. Anyone interested can email me 
directly and I'll forward the pdf.

-Jeff Corbin

"In spite of the fact that 97-98% of the climate researchers most actively 
publishing in the field accept the basic tenets of the Intergovernmental Panel 
on Climate Change's (IPCC) findings (Anderegg et al. 2010), there is a 
consistent undercurrent of climate  skepticism among the general public 
(Leiserowitz et al., 2011). To some extent, this skepticism is fueled by high 
profile speakers who offer "the real view" of climate science. Our campuses 
recently hosted two such speakers: Dr. Ivan Giaever at Rensselaer  Polytechnic 
Institute and Christopher Monckton (also known as Lord Monckton) at Union 
College. (Mr. Monckton's presentation can be seen at 
http://union.campusreform.org/group/blog/live-webinar-lord-monckton-at-union-college.)


While the intention of such speakers is often to muddy the waters with respect 
to climate science  (McCright and Dunlap, 2010), the effect at our campuses was 
to galvanize our students and colleagues to highlight the widely accepted facts 
of climate change  and the nature of expert scientific consensus on this topic. 
This communication was achieved using social media and follow-up events that 
raised the profile of climate change discussions. These events proved to be so 
successful that we offer our experiences  so that others can capitalize on 
similar visits by climate skeptics by converting them into "teachable moments.""
