Muy bueno. Siempre he pensado que cualquier estudio sobre el clima que no incluya gráficos de variaciones orbitales, no debería ni ser publicado.

Abdussamatov - The New Little Ice Age Has Started

Abstract

Since 1990, the Sun has been in the declining phase of the quasi-bicentennial variation in total solar irradiance (TSI). The decrease in the portion of TSI absorbed by the Earth since 1990 has remained uncompensated by the Earth's long-wave radiation into space at the previous high level because of the thermal inertia of the world's oceans. As a result, the Earth has, and will continue to have, a negative average annual energy balance and a long-term adverse thermal condition. The quasi-centennial epoch of the new Little Ice Age has started at the end 2015 after the maximum phase of solar cycle 24. The start of a solar grand minimum is anticipated in solar cycle 27±1 in 2043±11 and the beginning of phase of deep cooling in the new Little Ice Age in 2060 ± 11. The gradual weakening of the Gulf Stream leads to stronger cooling in the zone of its action in western Europe and the eastern parts of the United States and Canada. Quasi-bicentennial cyclic variations of TSI together with successive very important influences of the causal feedback effects are the main fundamental causes of corresponding alternations in climate variation from warming to the Little Ice Age.

artículos de investigación sobre dinámica solar, reconstrucciones, rayos cósmicos,... (centro RESOLVE)

CitarReSoLVE (Research on SOlar Long-term Variability and Effects) is a Center of Excellence established in 2014 and funded by the Academy of Finland. We are a group of 5 research teams from University of Oulu, and Aalto University focused on studying the long-term solar variability and its effects in near-Earth space, atmosphere and climate.

New Paper: Most Modern Warming, Including For Recent Decades, Is Due To Solar Forcing, Not CO2

Though advocates of the dangerous anthropogenic global warming (AGW) narrative may not welcome the news, evidence that modern day global warming has largely been driven by natural factors – especially solar activity – continues to pile up.

Much of the debate about the Sun's role in climate change is centered around reconstructions of solar activity that span the last 400 years, which now include satellite data from the late 1970s to present.

Mapa de correlación entre el sol y la temperatura en la Tierra, como se ve es el Sol el que controla perfectamente la temperatura, en los trópicos son las nubes la que hacen que la correlación sea negativa.

Acabo de leer esta noticia que creo que está relacionada con el tema. Lo extraño es que según indica ya hace tiempo que está sucediendo:

http://noticiasdelaciencia.com/not/27931/la-radiacion-espacial-se-esta-volviendo-mas-peligrosa/

Como estaba previsto, la menor actividad solar hace que los rayos cósmicos que llegan a la Tierra están aumentando mas de lo que se esperaba.

No tan extraño, se ha ido comentando: https://foro.tiempo.com/los-rayos-cosmicos-y-el-clima-t103655.0.html

Afecta no solo a los viajes espaciales y satelites también a los vuelos aereos (tanto a personas como equipos), son particulas de alta energía que penetran hasta la tierra y capaces de romper equipos electrónicos y cadenas de adn,.

En el minimo de Maunder, podriamos tener periodas calidas como de Deciembre 1675 al Verano 1676 o el año 1680 (Septembre record en Paris) o el Enero 1708 sin helado. Pero la actividad baja aumenta las olas de frio y los años frios. Y los stratus.
Y la gente es en depresion cuando la actividad baja.

405 thousand year climate cycle discovered related to Earth's orbit around the sun

Scientists drilling deep into ancient rocks in the Arizona desert say they have documented a gradual shift in Earth's orbit that repeats regularly every 405,000 years, playing a role in natural climate swings. Astrophysicists have long hypothesized that the cycle exists based on calculations of celestial mechanics, but the authors of the new research have found the first verifiable physical evidence. They showed that the cycle has been stable for hundreds of millions of years, from before the rise of dinosaurs, and is still active today.

Hola.

Vuelvo al ataque con lo mismo de siempre, pero contado de otra forma.
