NASA has released detailed global climate change projections. If you would like to know what these projections are please drink from this data firehose.

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

At 12 TB I think just getting the files would take days of downloading.

I have 25 mbs which equals to 1041:40:00 (hh:mm:ss) That is 25 mbs perfect connection with no errors or drops. 1041 hours equals 43+ days.

Let's see if these fare any better than the projections used by the IPCC ... http://esr.ibiblio.org/?p=5297 "The most recent climate model simulations used in the AR5 indicate that the warming stagnation since 1998 is no longer consistent with model projections even at the 2% confidence level." Kudos to them for publishing these, though. If they are rotten, it ought to be easy to tell.

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 substantial increase in the ocean surface temperature anomaly trend since 1998. ... The global surface temperature datasets are clearly a moving target. So while I’m sure this latest analysis from NOAA will be regarded as politically useful for the Obama administration, I don’t regard it as a particularly useful contribution to our scientific understanding of what is going on.

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

Indeed. The image at the top of the page (presumably the worst case scenario) has no legend. I'm guessing that the red is desert, but what counts as temperate? The South America blue or the South Africa yellow? Or are the colors a delta from the current temperatures?

It's amazing how easy it is to turn a 12TB deluge of pristine scientific data into something completely meaningless.

One could make the visualisation app work for a reduced data set and then constantly add to it whilst downloading. It would also make development easier. So you start with 2-3 years, make the app, make some scripts to automatically download and process what you need to process, and then add the other 147-148 years. This means... downloading only 164 - 245 GB of data... that'll keep me and my 10mbps broadband busy for more than 2 days :)

Would it go significantly quicker if you downloaded it to a VPS instead of your home?

You'd think some spots on the globe would get colder or rainer, no? Also this map makes it appear Antarctica will get colder? Or maybe that map is a stock image?

Those who deal with climate data are used to huge data sizes and are usually equipped with fast internet connections. You can also work with the data within AWS. The files come split in logical 750MB parts. There are different aspects of the data which come separately.
