A quick update: A lot of spam profiles were removed in the last few days, do complain if we removed any legitimate ones by mistake! Also, preliminary data for all triples with c no more than 10^18 has been available from our data page for a while now, although it is (of course) still preliminary at this point. Many thanks to our dedicated users, and we’ve now moved onward to further reaches of the search space!

- BURP: Short film "Uyir" by Danan completed rendering
03.12.2015 17:54 Uhr
Once again Danan has completed work on a movie, this time the short film “Uyir”. The storytelling style is recognizable from his earlier works Vetri and Tripping but has a different emotional twist this time.
657 contributors donated a total of around 690 CPU-months to rendering some of the more complicated parts of the movie.
You can watch the movie and comment on it in his thread in the forum.
- CAS@home: cas@home project status
01.02.2016 09:15 Uhr
The main application running on CAS@home is the TreeThreader which predicts protein structure. After finishing a big campaign in Oct 2015, there have been sporadic TreeThreader jobs running on CAS@home which is around 200 sequences to predict every month. Currently, the TreeThreader application provides a public service FALCON to allow worldwide biologists submitting their protein sequences for structure prediction, and CAS@home is the backend computing platform for this public service. This service has just been open to the public, and it expects more biologists to use it in the near future with a recent publication. Apart from the jobs from FALCON, there will also be another campaign of TreeThreader between Feb and May 2016 to prepare for the CASP event . As usual, CAS@home appreciates all the support from its volunteers!
- climateprediction.net: Human influence on climate in the 2014 southern England winter floods and their impacts
01.02.2016 17:27 Uhr
Human-induced climate change increased the risk of severe storms like those that hit the south of England in the winter of 2013/14, causing devastating flooding and costing several people their lives.
The preliminary results of this study have been on our website since the time the flooding happened , but now we have looked not only at the rainfall, but also the influence of anthropogenic greenhouse gas emissions on the atmospheric circulation and how this propagates from rainfall, to river flow down to the direct impact of flooded houses in the river catchment zones.
We found that anthropogenic greenhouse gas emissions increased the risk of the once-a-century wet January in 2014 by 43% (uncertainty range: 0–160%). The increase in extreme rainfall that led to the flooding in 2013/14 was the result of two factors associated with global warming: an increase in the water-holding capacity of the atmosphere (a thermodynamic factor) and more January days with westerly air flow (a dynamic factor). The authors identified that approximately 2/3 of the increased risk could be attributed to thermodynamic changes in the atmosphere, and 1/3 to dynamic changes.
Among the worst-affected areas were Somerset, Devon, Dorset and Cornwall in the south west, and the Thames Valley in the south east. This first-of-its-kind, end-to-end study looked at the event from start to finish, taking in atmospheric circulation, rainfall, river flow, inundation, and properties at risk. The research is published in the journal Nature Climate Change.
To be able to do this world we made use of over 100,000 weather@home simulation of possible weather in January 204 in both the current climate and one in which there was no human influence on the atmosphere. Researchers analysed more than a hundred thousand simulations of possible rainfall in the UK run by citizens from all over the world.
For the hydrological modelling of the Thames river catchment done at CEH we showed that the changes in atmospheric circulation and precipitation caused higher peak 30-day river flow, while flood risk mapping revealed a small increase in flood risk for properties in the Thames catchment.
The heightened risk of rainfall found in the meteorological modelling led to an increase in the peak 30-day river flow of 21% (uncertainty range: -17–133%) and about 1,000 more properties at risk of flooding (uncertainty range: -4,000–8,000). These numbers show that we need to run the impact models as well as analysing the meteorology as the anthropogenic signal does not propagate linearly. Furthermore, each of these steps reflects different sources of uncertainty, but we find overall that there is a substantial chance of more properties having been placed at flood risk because of past greenhouse gas emissions, leading to potential damages that could be part of the losses incurred in 2013/14.
Some examples of the media coverage this work got:
- climateprediction.net: Man-made climate change as important as natural variability in December’s record rains
14.01.2016 08:54 Uhr
First results of our new study together with researchers from the Royal Netherlands Meteorological Institute show that human-induced climate change approximately doubled the chances of an exceptionally warm December in Central England, and significantly increased the chances of high rainfall further North.
Ocean conditions in the Atlantic, and possibly the strong El Niño conditions now seen in the Pacific, also increased the odds of exceptional warmth and rainfall by similar amounts, we found, while random weather variability plays also a large role.

- climateprediction.net: CPDN and the Paris agreement
16.12.2015 00:10 Uhr
The negotiations in Paris finished with an unexpectedly strong agreement to aim to limit warming to “well below” 2C, and even “to pursue efforts to limit the temperature increase to 1.5C”.
In two articles in The Conversation and Carbon Brief, CPDN PI Myles Allen explores the implications of a 1.5C goal. Whether a 2C or a 1.5C goal, limiting global warming is only achievable if global anthropogenic greenhouse gas emissions reach zero within this century. To reach a more ambitious goal in global mean temperature stabilisation zero emissions need to be reached sooner than for 2C. So far the simple part of the story.
Not all greenhouse gas emissions are CO2, although it is the most important and longest lived greenhouse gas, and ideas to reduce those are only beginning to be explored. Furthermore, all emission reduction scenarios even for a 2C world include negative emissions in the form of Carbon Capture and Storage. These technologies exist in principle but have not been implemented, to reach a 1.5C stabilisation scenario these technologies would need to be available sooner and on a larger scale argues Allen. In summary, limiting global warming to 1.5C is definitely possible but requires commitment and fast action in developing appropriate political instruments and the necessary technologies.
Most directly relevant for the day to day work of the CPDN team is the fact that in the Paris agreement, Loss and Damage is treated separately from Adaptation. As argued in a paper published earlier this year by Allen Thompson and CPDN’s Fredi Otto, this is particularly important from a climate justice point of view. Not in terms of compensating for losses which is explicitly excluded from the new agreement but in terms of recognition of the fact that there are impacts of climate change we cannot adapt against and these impacts are particularly damaging in the most vulnerable parts of the world.
Currently however, there is no definition of Loss and Damage and concrete ways of dealing with Loss and Damage are to be evaluated at the next meeting of the Conference of the Parties in 2016. Whether and to what extend the science of event attribution is relevant in this context is amongst others being discussed at this weeks fall meeting of the American Geophysical Union (AGU). Watch Fredi Otto discuss some of the major challenges in defining Loss and Damage and Dann Mitchell giving an example of how event attribution can be done for variables beyond meteorology in the AGU on demand session.
