- climateprediction.net: Change needed to avoid ‘paralysis’ in climate policies
04.08.2015 13:54 Uhr
Climate scientists, including climateprediction.net’s Dr Friederike Otto and Professor Myles Allen, are calling for an overhaul of the way climate change pledges are assessed, in order to avoid ‘indefinite procrastination’ on designing efficient mitigation policies.
Writing in Nature Climate Change, they say that the ‘pledge and review’ approach that will form the basis of commitments made at the UN climate change negotiations in December, presents an opportunity to link mitigation goals explicitly to the evolving climate response.
“Scientific uncertainty about the long-term impacts of climate change is often used as an excuse for inaction, or as a basis for recommending highly precautionary worst-case-scenario strategies, which may be unpalatable to policy makers juggling economic and political interests,” said Dr Friederike Otto of Oxford’s Environmental Change Institute, lead author of the paper.
“Human-induced warming has brought us 10% closer to 2°C since 2009. So any country whose government acknowledged in 2009 that CO2 emissions must reach net zero by the time temperatures reach the target stabilisation level of 2°C should be 10% of the way there now. However there still is no overall strategy to achieve this.”
The authors, who include the Oxford Martin School’s Professor Myles Allen, argue that strategies should be ‘anti-fragile’, meaning they are not just robust under uncertainty but more successful under a wide range of uncertainties, including scientific, economic and political risks. Learning from trial and error is an integral part of such an ‘anti-fragile’ strategy, allowing for evolving knowledge to be incorporated at low costs.
They looked at what climate policy makers could learn from adaptive management techniques, to create an approach to mitigation that more fully accounts for the set of risks that governments care about, is less dependent on a globally binding mandate, and which could, therefore, be a better way to preserve flexibility in climate mitigation.
They recommend an adaptive strategy grounded on an index of the warming attributable to human influence, which is itself based on observed temperatures. Calculated in 2014 the rise in global mean temperature attributable to anthropogenic influences was 0.91?C.
In contrast to global mean temperature the ‘attributable anthropogenic warming’ index is not subject to high year to year and decadal variability. It also requires no complex modelling and could be updated on an annual basis, allowing governments to review their pledges to reduce greenhouse gas emissions.
The paper outlines three policy options using the index and concludes that indexing to attributable anthropogenic warming allows a transparent link between the policy instrument and the policy goal. It is a simple way to monitor the overall consistency between the evolving climate change signal, individual countries’ pledges and the overall goal of achieving net zero CO2 emissions by the time we reach 2°C of human-related warming.
Dr Otto concludes: “At a crucial time for climate negotiations, the proposed index offers a transparent and accountable method of evaluating climate policies that deals with the remaining uncertainty of the climate response, which has so far had a paralysing effect on climate change policies.”

- More information on the index can be found at www.safecarbon.org, an up-to-the-second index of human-induced warming relative to the mid-19th century (1861-80) and cumulative carbon dioxide emissions from fossil fuel use, cement manufacturing and land-use-change.
- Human-induced warming is currently increasing at 1.8 hundredths of a degree per year, or 0.6 billionths of a degree per second.

- Quake-Catcher Network Sensor Monitoring: If You're Having Trouble Connecting Since the Big Move to CalTech….
23.07.2015 12:09 Uhr
Some people are having trouble connecting — this is probably due to the operating system (it seems to mostly be a Windows problem) caching the old qcn.stanford addresses, and not liking the forwarding to qcn.caltech (probably a “safety feature” in Windows). You can try doing a “Reset Project” in the BOINC Manager program to see if that will correct things. If not, you may have to do a more drastic “Remove Project” and then “Attach Project” to our new URL: http://qcn.caltech.edu/sensor You may want to first go to the “Your Account” page at the website to make sure you know which email address you used, and find/recover your password information as you will need this to login again.
- climateprediction.net: Weather@home 2015 Western US Drought: All models have been sent out, about half have come back
23.07.2015 11:01 Uhr
So, thanks to the fantastic efforts of our volunteers, all 22,000 models for this experiment have now been downloaded to run on people’s home computers, and nearly half have finished running and have been uploaded back to our servers.
The plots for the results so far have been updated to include all the models that have been returned to us – currently sitting at nearly 8,000 models!
Thanks again to everyone who has helped us with this experiment by running our models on your computer, we couldn’t do this without you.
There are 3 plots for each state, here’s one of them showing temperature in California:

You do not have to do anything on your BOINC account – as the QCN addresses/URLs are being forwarded automatically from Stanford to Caltech.

- climateprediction.net: New Climatology Results for Western US Drought Experiment
15.07.2015 09:49 Uhr
We now have the first results for our Climatological simulations, investigating the influence of removing the ‘blob’ of warm sea surface temperatures off the western US coast.
The ‘blob’ has a strong influence on the temperature, for example the climatological simulations without the ‘blob’ are colder than the actual or natural simulations.
In the climatological simulations, it is interesting to see a different response in the precipitation between the different states. This is something our scientists will be investigating in more detail in the upcoming weeks.
There are 3 plots for each state, here’s one of them showing temperature in California. The experiment is looking at two possible influences on the drought in the Western US – climate change and the “blob”. In the plot below, there are 3 sets of data:
- “Actual” – these are models that use observed data to simulate the climate
- “Natural” – these are models that show a “world that might have been without climate change”
- “Climatology” – these are models that include climate change, as observed, but have removed the “blob”
There are still a few thousand models left to run, so please do sign up if you haven’t already, and help us answer this fascinating and important question!

- Moo! Wrapper: Out of work
12.07.2015 11:40 Uhr
There’s no more work available at the moment due to the distributed.net keymaster hardware failure. Our local cache was just also depleted, which lasted for about two days. So let’s finish what we have and then move on to backup projects (yes, they are always good idea to have) while we wait for the distributed.net staff to repair keymaster. Rest assured, they are working hard to get the keymaster back up. As soon as that happens, we’ll get fresh work out for our hungry systems to crunch.
For more details and latest developments, please read http://blogs.distributed.net/. Thanks for your patience!
- Moo! Wrapper: Disk maintenance and work generation woes
10.07.2015 18:44 Uhr
Project was down today between 18:00 and 21:30 EEST (that’s from 15:00 UTC/7:00 PST to 18:30 UTC/11:30 PST) for about 3 and half hours while the previously failing disk was swapped with a backup disk and data was copied over. Now the project is running from a disk that’s not showing signs of collapsing due to read errors. The backup disk is as old as the failed disk but hasn’t had that much use so it should last until the project server is migrated to a new server with SSD disks later this year.
This happened a bit unannounced as I took advantage of the D.net keymaster problems that seems to slow down our work generation for some reason. That’s also the why we run out of work before the maintenance and why we still don’t have full work buffers. Hopefully that will fix itself once the keymaster is back in action. In any case, our local proxy will eventually run out of work unless the keymaster will be resurrected.
For more information about the keymaster failure, please read http://blogs.distributed.net/2015/07/10/04/28/bovine/. Thanks and happy crunching once the dust settles!
