I originally started this blog to record my experiences in Ethiopia. It started out as a travel blog, but has now morphed mainly into a science blog on climate.

Civilisation needs a long term reliable power source if it is to avoid eventual collapse. Renewable energy cannot achieve this because a) it is inherently unreliable and requires gas backup, b) lasts less than 20 years yet requires huge areas of land/sea, and c) its renewal depends on steel, tarmac, plastics and heavy machinery. Nuclear Energy on the other hand is truly Zero Carbon neutral, lasts over 60 years and can if needed produce hydrogen, biofuel and recharge batteries at night.
The development of Nuclear Energy in the UK was damaged by a bad press, Chernobyl, an ..read more

December saw a rise in the global average temperature anomaly to 1.27C resulting in a final annual value of 1.13C for the year 2023. This represents an increase of just under 0.3C since 2022, the warmest year so far (as widely reported). My calculation is based on spherical triangulation and uses GHCN corrected land data and the latest HadCRUT3 sea surface temperature data. It is the same basic data as used by all groups (Berkeley, Hadley/CRU, NASA etc.)
Here is the data for the full year 2023

The Met Office are proposing to use a 10 year average temperature indicator to define when and if the 1.5 degree since industrial periods will be exceeded. The pre-industrial period is defined as 1850-1900 which is different from the 1961- 1990 baseline that are used for calculating station anomalies because this maximises the available station count. The offset for the preindustrial period is consequentially based on these anomaly values before 1900.
A comparison of the latest HadCRUT5 with my Spherical triangulation results shows an almost perfect agreement bet ..read more

A little late but here is my update on the global temperatures for October 2023, The method used is always by spherical triangulation. Temperature fell from the peak in September of 1.49 to 1.29 in October.

The well known result that CO2 radiative forcing is approximately 5.3 Ln (C/CO) [1] is confirmed here by comparing decadal global temperature anomalies with CO2 concentrations. Positive feedbacks are not needed to explain the observed warming. A value of Transient Climate Response of 1.6C is observed to confirm this. The Moana Loa CO2 measurements when combined with earlier estimates of emissions show that CO2 concentrations have essentially been increasing exponentially since before 1955. As a result we would expect resultant temperatures to increase linearly with time [see ..read more

The transient climate sensitivity (TCR) is the observed average warming of the earth following a doubling of atmospheric CO2 concentration. Effectively this means the observed average temperature when CO2 levels reach 560 PPM. The current average level of CO2 is 415 PPM and we measure the effective temperature of the earth each month relative to a normalised 30 year average. These average temperature anomalies vary from month to month and year to year due to internal effects like El Nino or Volcanoes. This September was the highest recorded temperature anomaly, but this does not mean that temp ..read more

September’s global average temperature was 1.44C. This beat the previous record high monthly temperature recorded in September 2016 (1.22C). There was a strong El Nino , and the Americas, Europe and Antarctica were all warmer than usual. Here is an animation of the temperature anomalies
A strong El Nino has developed and but what is more particularly apparent is strong warming in Antarctica which usually remains isolated and cool. This makes makes me wonder if sub surface volcanic activity is to blame.
Here are the updated monthly data.

Most of this summer saw variable weather and short spells of windy conditions across the UK, followed by a very hot spell at the beginning of September with little to no wind. The consequent sudden changes in wind power output needs flexible backup which can realistically only be provided with Gas power stations. So let’s see how the National Grid coped with providing sufficient power to keep the lights on, and what lessons can be learned.
Power generation by fuel type. Solar is an estimate from University of Sheffield. Wind power is also corrected to include non metered wind farms. (cl ..read more

Exaggerated claims of unusual temperatures
Summer 2023 saw a great deal of media fuss about excessive temperatures using plots such as figure 1, from the website Climate Reanalyzer. This display shows that the temperature on 4 July 2023 was 17.2°C, 1°C higher than the 1979-2000 average. This has been interpreted as corresponding to an extremely unlikely probability of 1/3.5 million, indicating imminent danger for humans. A very disturbing event in this climate alarmism was a speech by the Directeur General of the United Nations, António Guterres, saying in July 2023: ‘”The era of global w ..read more
