I don't know if there are any out there, but being a being a comedian doing a Climate Change Skeptic routine could be a hit.

Now back to the waste of tax payers (millions) moneys in the climate modelling scam. Of course those here who pray daily to them models will instantly object.

“Funding of multi-decadal regional climate predictions by the National Science Foundation which cannot be verified in terms of accuracy is not only a poor use of tax payer funds, but is misleading policymakers and others on the actual skill that exists in predicting changes [in the climate] in the future.”
R.A. Pielke Sr

The Failure Of Dynamic Downscaling As Adding Value to Multi-Decadal Regional Climate Prediction
The main issues, as I summarize from our paper are:

1. As a necessary condition for an accurate prediction, the multi-decadal global climate model simulations must include all first-order climate forcings and feedbacks. However, they do not [see for example: NRC, 2005; Pielke Sr. et al., 2009].

2. These global multi-decadal predictions are unable to skillfully simulate major atmospheric circulation features such the Pacific Decadal Oscillation [PDO], the North Atlantic Oscillation [NAO], El Niño and La Niña, and the South Asian monsoon [Pielke Sr., 2010; Annamalai et al., 2007].

3. While dynamic regional downscaling yield higher spatial resolution, the regional climate models are strongly dependent on the lateral boundary conditions and interior nudging by their parent global models [e.g., see Rockel et al., 2008]. Large-scale climate errors in the global models are retained and could even be amplified by the higher spatial resolution regional models.

4. Since as reported, the global multi-decadal climate model predictions cannot accurately predict circulation features such as the PDO, NAO, El Niño, and La Niña [Compo et al., 2011] they cannot provide accurate lateral boundary conditions and interior nudging to the regional climate models.

5. The regional models themselves do not have the domain scale (or two-way interaction) to skillfully predict these larger-scale atmospheric features.

6. There is also only one-way interaction between regional and global models which is not physically consistent. If the regional model significantly alters the atmospheric and/or ocean circulations, there is no way for this information to alter the larger-scale circulation features which are being fed into the regional model through the lateral boundary conditions and nudging.

7. When higher spatial analyses of land use and other forcings are considered in the regional domain, the errors and uncertainty from the larger model still persists thus rendering the added complexity and details ineffective [Ray et al. 2010; Mishra et al. 2010].

8. The lateral boundary conditions for input to regional downscaling require regional-scale information from a global forecast model. However the global model does not have this regional-scale information due to its limited spatial resolution. This is, however, a logical paradox since the regional model needs something that can only be acquired by a regional model (or regional observations). Therefore, the acquisition of lateral boundary conditions with the needed spatial resolution becomes logically impossible.

Finally, There is sometimes an incorrect assumption that although global climate models cannot predict future climate change as an initial value problem, they can predict future climate statistics as a boundary value problem [Palmer et al., 2008]. With respect to weather patterns, for the downscaling regional (and global) models to add value over and beyond what is available from the historical, recent paleo-record, and worse case sequence of days, however, they must be able to skillfully predict the changes in the regional weather statistics.

There is only value for predicting climate change, however, if they could skillfully predict the changes in the statistics of the weather and other aspects of the climate system. There is no evidence, however, that the model can predict changes in these climate statistics even in hindcast. As highlighted in Dessai et al. [2009] the finer and time-space based downscaled information can be “misconstrued as accurate”, but the ability to get this finer-scale information does not necessarily translate into increased confidence in the downscaled scenario [Wilby, 2010].

There was a CO2 forced hothouse event as Pangea broke up in the later Mesozoic, which was a time of great vulcanism. You can find Cretaceous dinosaur and temperate flora fossils in Arctic Alaska, and at the time of deposition the fossil beds were closer to the magnetic pole than they are now. Yes, we know how to measure the latitude where rocks were deposited through time using paleomag data. It is very valuable information if used properly.

That event has been well studied, so I will describe it in short posts. It is extremely relevant to the CO2 increase today, because we have a very good idea of CO2 concentrations at that point in time.

First, I must set the stage here, and I'm not sure if I will have enough free time to argue with these two fellows.

Chief. Do you even believe in science? I remember you saying that God turned on all of the lights in our universe at the same time, and the time it took for light to travel to our telescopes (or instrument, as you prefer) was instantly created.

You also seem to have a hard time with people who go to college. Didn't you say as much? I want this clear because we are getting into a lot of really new science here, and all you are concentrating on is statistics and how to misuse them. Don't worry. This is very common unless you are used to working with numbers, so ignorance in this area is forgiveable. Ed basically just gave you a lesson in the statistics of small numbers, which is meaningless. Statistics improve as the dataset grows.

I'm not trying to be mean.

So I'm setting the stage for a scientific argument here with Rick and The Chief. Anyone else is free to step in.

Does anyone know what the troposphere is?

No come on now Basey, remember you are not talking to me anymore? Besides you refused to allow the heresy of answer to my questions passing your lips, so to speak.

Anyway Mama, bless her heart, has me doing the delayed spring cleanup and roto tilling of compost into our king size and hugely productive garden so i don't have much time till later.

Our ever vigilant friend Ron (where is he by the way?) sent me this link to post. I think we've all seen it before but it is still useful in refreshing closed minds.

Alien Planets Could Shed Light on Earth's Climate Future


Understanding climate change

Jim Green, NASA’s Planetary Science Division Director, said that one goal is to examine a variety of planetary bodies as a system, to see if there are trends or similarities. He also pointed out that from a planetary scientist’s perspective, climate change on our planet is not a new thing.

"Earth’s climate has done nothing but change," Green said.

Michael Meyer, lead scientist for the Mars Exploration Program at NASA Headquarters, also pointed out that we should never become complacent in our scientific understanding. For instance, he said that while climate models have not been able to make early Mars warm enough to sustain liquid water on its surface, the same can be true for models of the young Earth.

I remember you saying that God turned on all of the lights in our universe at the same time

Never wrote anything of the sorts. I do not believe in a creator. Rather that the Universe has no beginning nor end. It is the ultimate power. It is infinite and has not concept of time. Beginning nor end. Black and White Holes substantiate my belief. That is a whole different ball game on the other side of them holes. Holes that we humans have absolutely no idea what they hold on their other sides. None. Zero. Only some mathematical human perceptions that are constantly disputed amongst one an other of those experts math formula generators.

I thought I told you to shut up

Anyway, I think that is a thephi, which plots the capacity for instability through a vertical slice of atmosphere. Its really cool as any para gliders will tell you. I don't know why a geologist would know much about them unless of course you live in Tornado alley

How bout you fk off. K.

Tephigram. Is weather forecasting, not climate. We all know how accurate that is. Weather forecasting that is. NOAA forecasted an above avg snow year in the Sierra back in Oct of 2012. Not. They forecasted a below normal snow fall year in Oct of 2010. Not. Record year. On and on. Oh the forecasting/models.

This is a little off topic so please forgive me. For along time after the BP Gulf I'll spill I tried to find information on what happened to the many Sperm Whales in the area. There was a news blackout in regards to it. Apparently Americans have to use the Freedom of Information Act to see photos of dead whales;
http://www.huffingtonpost.com/2012/10/24/sperm-whale-dead-gulf-of-mexico-bp-oil-spill_n_2010221.

I remember reading an account about turtles, dolphins and whales being burned en masse. I'll bet we never see those photos. We are supposed to think one whale died and the rest 'migrated'. Yeah, they migrated to Hell before they went to Heaven.

This cover up could probably be attributed to the power of BP rather than NOAA. At the time, ALL reporting STOPPED after the discovery of the first dead whale.
