Heavy snowfall in Bulgaria

Amid heavy snowfalls, Bulgaria’s Road Infrastructure Agency issued a call for motorists to avoid travel in north-western Bulgaria, unless in the event of emergency.

16 Dec 2018 – The road agency also called for caution given the “Code Yellow” warning of potentially dangerous weather because of heavy snowfalls in the regions of Vidin, Montana, Vratsa, Sofia – both the city and the district – Pernik and Kyustendil.

The road agency said that its 27 regional offices and snow-cleaning companies were in 24-hour mode, ready to respond to keep the national road network functioning.

In capital city Sofia, heavy snowfall began at about 10am on December 16 and was forecast to continue throughout the day.

  1. How does the Sun drive climate change?

    The dispute between scholars that favor a periodical interpretation of climate changes, mostly based on astronomical causes, and those that prefer non-periodical Earth-based explanations has a long tradition that can be traced to the catastrophism-uniformitarianism dispute and how the theory of ice ages (now termed glaciations) fitted in.

    Prior to the scientific proposal of ice ages in 1834, most scholars that cared about the issue believed that the Earth had been progressively cooling from a hot start, as tropical fossils at high latitudes appeared to support. By 1860 scholars had been convinced by evidence that not one but several glaciations had taken place in the distant past. By then scientists trying to explain the cause of past glaciations were split in two. Those following Joseph Adhémar, who had already proposed orbital variations in 1842, and those following John Tyndall, who proposed that they were due to changes in GHGs (greenhouse gases) in 1859, particularly water vapor.

    For a time, the anti-cyclical, pro-GHG camp had the advantage, after James Croll’s hypothesis was rejected, and Svante Arrhenius in 1894 proposed CO2 as the responsible GHG. But then, doubts about the CO2 effect and a new formulation of the cyclical astronomical hypothesis by Milankovitch appeared that fit popular geological reconstructions of past glaciations. This swung the field again.

    By the late 1940’s Milankovitch theory was well established, particularly in Europe, but not so much in America where reconstruction of Laurentide ice-sheet changes did not match the theory very well. But in the 1950’s a new consensus formed. The GHG theory was reinforced by Suess, Revelle, and Keeling’s work, while carbon dating led to glacial reconstructions at odds with Milankovitch theory.

    In the 1960’s and early 70’s Milankovitch theory was discredited with only a handful of followers left. The anti-cyclical, GHG explanation enjoyed wide consensus, but due to the cooling at the time, scholars believed other factors must be at play. Then disaster struck for the anti-cyclical camp. In 1976, Hays, Imbrie, and Shackleton, analyzing Indian Ocean benthic cores for the past 450,000 years and showed that glaciations followed some of Milankovitch frequencies within 5% error. A 140-year quest had ended, and the cyclical orbital supporters had won.

    Of course, GHG supporters are bad players and did not accept the defeat graciously. Since it was soon discovered in ice cores that GHGs followed orbital changes (as they should), it was soon proposed (and accepted without evidence) that they were required to amplify the orbital changes and to maintain inter-hemispheric synchroneity. Trying to turn the defeat into a victory, they claim that the frequency is set by Milankovitch but a great deal of glacial-interglacial climate changes are due to GHG changes.
    I have already shown some evidence for that in my previous articles:

    Do-It-Yourself: The solar variability effect on climate

    Do-It-Yourself: Solar variability effect on climate. Part II

    I have also shown that ENSO is under solar control:

    But this is really interesting
