Olá, meu 8 (oito) leitores!
Escrevo apenas para lembrar que retomaremos nossas atividades aqui em Frumentarius em julho! Logo voltaremos a comentar sobre um pouco de tudo… Por falar nisso, o Inverno este ano será forte no Brasil… Convém estar preparado.
Segue artigo interessante sobre a possibilidade de uma nova Era Glacial (ou uma versão mini) para daqui a 15 anos… Espero que só vem o frio com ela…
Diminishing solar activity may bring new Ice Age by 2030
LOMONOSOV MOSCOW STATE UNIVERSITY PRESS RELEASE
The arrival of intense cold similar to the one that raged during the “Little Ice Age”, which froze the world during the 17th century and in the beginning of the 18th century, is expected in the years 2030—2040. These conclusions were presented by Professor V. Zharkova (Northumbria University) during the National Astronomy Meeting in Llandudno in Wales by the international group of scientists, which also includes Dr Helen Popova of the Skobeltsyn Institute of Nuclear Physics and of the Faculty of Physics of the Lomonosov Moscow State University, Professor Simon Shepherd of Bradford University and Dr Sergei Zharkov of Hull University.
It is known that the Sun has its own magnetic field, the amplitude and spatial configuration of which vary with time. The formation and decay of strong magnetic fields in the solar atmosphere results in the changes of electromagnetic radiation from the Sun, of the intensity of plasma flows coming from the Sun, and the number of sunspots on the Sun’s surface. The study of changes in the number of sunspots on the Sun’s surface has a cyclic structure vary in every 11 years that is also imposed on the Earth environment as the analysis of carbon-14, beryllium-10 and other isotopes in glaciers and in the trees showed.
