Some things deserve repeating.
One of those things, which happened to come up in conversation recently, is that climate change has its most profound effect on extreme events. Climate change is a change in the probability function (the odds for each possible outcome) of weather, and when you look at probability functions you find that if they change in the way we expect them to, it can increase (or decrease) the chance of extremes by a surprising amount.

Temperature varies, through day and night, from day to day, from month to month, and year to year. The most common way to note its changes is to record each day’s high temperature and low temperature, which has been done at Kremsmuenster, Austria since 1876. Here’s a snapshot of five years of that data, from 2010 through 2014:

An idea for capturing CO2 & storing
heat under your new house
Question: “Is it a good idea or barmy?”
The mineral olivine is taken as the example for this note. It absorbs CO2 slowly at ambient temperature (25°C) but much faster at a temperature of 186°C. Continue reading Capture CO2 under your new house
A new paper by Risbey et al. examines the so-called “pause” in global temperature, and demonstrates convincingly that it wasn’t a real phenomenon, it was just random fluctuation that can look like a pause all along. I’ve been saying this for some time now. I’m also a co-author on the paper.

‘An idea for storing renewable energy’
was first posted on ccq.org.uk, 25th March 2012
Question “Is it a good idea or barmy?”
Points:
1. There are times when renewable energy cannot be used. Sources tell me that 20% or more of wind energy is grounded (i.e. thrown away) because sometimes the generated energy cannot be used. Other renewable sources (solar, wave power) are also intermittent. Biomass is an exception. Continue reading An idea for storing renewable energy (2012)
I’ve been studying how temperature has changed over the years in the Arctic. The longest record I’ve got is for land areas only, from the Berkeley Earth Surface Temperature project, which starts way back in 1750:

This was an appendix to Garden Cities and Green Evolutionary Settlements but that’s buried too deep to casually reference. It is reproduced here to show that lifestyles can be affected by a different structure of local finances. I look forward to the Butlins designing Green Evolutionary Settlements to begin the transformation towards more sustainable ways of living.

Have you found that interesting page on a UK government website is missing? Do you suspect that it contained information inconvenient to present government?
Looking up a previous post on the effect of climate change on the safety of coastal nuclear power stations, I found :
The report relies on the HadRM3 Regional Climate Model. This may underestimate or omit the effects of certain climate feedbacks which are mentioned on the NERC website:
– reduced sea ice cover – reflecting less of the sun’s heat back out to space, changing ocean circulation patterns
– less carbon dioxide absorption by the oceans
– increased soil respiration
– more forest fires
– melting permafrost
– increased decomposition of wetlands
I thought I might refresh my memory but the NERC link gives Continue reading Inconvenient information: Page not found

We need to reduce greenhouse gases in the atmosphere, and we need to do it quickly. The main ones increased by humans are carbon dioxide (CO2), methane (CH4, the main component of natural gas), and nitrous oxide (N2O).
How are we doing?
