[FRIAM] Climate Change

[Marcus Daniels]

"My problem is that I fear that we have passed the point of no possible remedy.  There was a meme which was a graph of global mean temperature for the last several centuries.  There was a sharp transient to the high side in recent decades."


Hippopatumus in Cologne could be fun.

And of course, the errors can be in either direction.  Large organizations tend to avoid controversy, not seek it out.

Other alternative views can be quite terrifying...

How about boulders like below being tossed around in storms near Miami, Shanghai, etc.

"In 1990 the IPCC predicted a temperature increase of 0.3 degrees centigrade per decade. In 2014 they reported an actual increase of 0.05 degrees centigrade for the previous 15 years."


The second plot gives an idea of how these estimates, based on observation, could go wrong.  However, the first plot in the first image shows a trend over a larger interval, which is consistent with matching the observational & simulation outputs for longer periods.

Thank you, I do appreciate.

Let me start with my background. I have done modeling for predictions in engineering applications as a major part of my professional career of 40 years. I am now doing deep learning for making predictions. (Not necessarily relevant to this discussion, but I do combine ABM to get the emerging properties of the system as part of the deep learning exercise - a very exciting endeavor).

In my career, I have made many technical mistakes. I guess this is part of making predictions based on models. I do not have any climate modeling expertise, but I do measure their success in the accuracy of the model's predictions.

In 1990 the IPCC predicted a temperature increase of 0.3 degrees centigrade per decade. In 2014 they reported an actual increase of 0.05 degrees centigrade for the previous 15 years.

Maybe they are right in their new disaster predictions? IMO it would give them some credibility if they admit the uncertainties.

Yes, I think so.  The trick, I think, is to demonstrate respect for those with whom we disagree.  If someone posts, without rancor, an argument (preferably with data) arguing that the models are wrong in a crucial way, I know *I* would be interested.

I've posted tons of contrarian and stubborn, perhaps even stupid, opinions and have been treated with respect.
