Several comments in this thread mention visualization. These data can be easily visualized with the Unidata IDV [1] (same ppl that make THREDDS). For those interested, go to the IDV dashboard, "Data Choosers" tab and enter http://dataserver3.nccs.nasa.gov/thredds/catalog/bypass/NEX-... for the catalog. At that point you can browse the dataset, add the data as a data source, subset it (serverside), and visualize it. I…

I just want a single image that tells me the expected better/worse degree of change in suitability for agriculture and habitation. Maybe red would mean a lot worse than today, and green would mean a lot better. An absolute image (of today's climate) would help make sense of the deltas also.

>expected better/worse degree of change in suitability for agriculture and habitation

What kind of agriculture? Every plant species is different, and various growing techniques are suited to different conditions.

What kind of habitat? Every dwelling is different, and every person has unique requirements of it.

See the problem?

The key takeaway: > Noting that “buoy data have been proven to be more accurate than ship data,” the new study applies a new “bias correction” to address the difference between them.

..by adding a correction to the more accurate buoy data, generating a combined dataset that does not match trends in the satellite data, gold-standard terrestrial data, balloon data, or oceanic temperature data. It also reduces the long-term temperature trend to the pre-1950 trend (i.e., pre-anthropogenic trend). This is a paper that requires a significant degree of corroboration rather than simple endorsement becaus…

Pre-1950 trend? I don't get it. What happened in 1950?

"When confronted with the fact that scientists as a general rule are scrupulously honest" citation needed

Here are some citations showing the exact opposite. Believe it or not, scientists are humans and have biases, are occasionally bad actors, and sometimes just need to get that grant. http://publicationethics.org/news/cope-statement-inappropria... http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1182327/ - "Why Most Published Research Findings Are False" http://www.thelancet.com/pdfs/journals/lancet/PIIS0140-6736%... - Edit…

The second and third links are for medical research. Anything similar for climatology?

Would you be open to Kickstarting this project if the resulting repo was public/open source on Github? EDIT: I should be clear. I would not be writing the code. I'd do the legwork to find someone (and pay them) who is familiar working with OSM to process the data, create the dataset, and build a javascript frontend to visualize it. The result would be open source. I would accept no funds whatsoever for this. I don't…

In fact, I don't think there's even a way to get historic temperature by day/location anywhere. That would be a useful thing to add, just the ability to down small subsets of the data.

The entire dataset is 12TB because it contains _daily_ global 25x25km maps for all years between 1950-2099 probably for a bunch of different variables. You don't need to download the entire thing to get the gist of it, although it probably would have helped if they also delivered a digest version with for example yearly or 5-yearly averages. Edit: There is also a THREDDS data catalog present which allows you to extra…

If you could boil it down for the busier among us: on a scale of "screwed" to "really screwed", how screwed does it say we are? ;)

Really? You actually believe the hysteria?

Yea and in other posts she's always defending Ted Cruz. Really makes you trust her sciencyness.

What does Ted Cruz have to do with anything? Do you know anything about his positions? Wasn't Al Gore that said all of the polar ice caps would be melted by now? Wasn't it Gore that also predicted a dramatic increase in hurricanes? When did that happen? Cruz is Linus Pauling compared to Al Gore.

It looks like you can only do one day at a time though?

My ultimate goal is to make a list of cities with less than 10 90 degree days per year. I still don't see a way to do that on wunderground.

Rebuttal: http://judithcurry.com/2015/06/04/has-noaa-busted-the-pause-... The greatest changes in the new NOAA surface temperature analysis is to the ocean temperatures since 1998. This seems rather ironic, since this is the period where there is the greatest coverage of data with the highest quality of measurements – ARGO buoys and satellites don’t show a warming trend. Nevertheless, the NOAA team finds a substantia…

Ahh, yes, the famous Judith Curry, known by climate scientists as a quack who seems to be rather incapable of understanding the most basic notions of physics necessary to build (or refute, for that matter) any sort of argument in climate sciences.

Are these the same climate scientists that were accused of fabricating data by adjusting the adjustments in order to support their political desires? Those climate scientists? Because if anyone is having trouble with credibility right now it's the entire industry of grant-chasing climatologists. The IPCC even admired that climate policy was a means to redistribute world wealth. Does that not scare anyone? Has Al Gore become a billionaire because of a climate 'crisis' he helped invent? I don't know anything about this Curry woman but I do know that political ideology has a disproportionate influence in climate science because it's an ideal Trojan horse for Marxism. It's no accident that extreme leftists are the ones most passionate about carbon. Carbon represents freedom. It's that simple. Even the founder of Greenpeace admits that the whole global warming industry is nothing more than a political scam.

I'm sure someone here is already making a visualization with the dataset.

I sure hope so because I am very very curious. Surely there are a lot of researchers that will love to jump into this data and manipulate it somehow. It's a good time to be studying climate change now... your dissertation is right here :D

Assuming the data is accurate and hasn't been 'adjusted' or 'corrected.' The whole climate business is a corrupt mess. Raw data over the years has been 'fixed' and policy is being made from 'models.' Yet what non partisan organization checks the models? The IPCC certainly doesn't. It's all a scam. We had global cooling fears in the 1970s. Then warming. Now "climate change." Yet industrial carbon output has risen exponentially and consistently since the industrial revolution yet temperatures haven't, thus calling into question that increased carbon dioxide raises temperatures. Such a disgusting mess.
