Link to climate forcing by the sun found by the SATIRE (Spectral And Total Irradiance REconstruction)

Our resident solar physicist, Dr. Leif Svalgaard sends word of this paper: ​ Climate responses to SATIRE and SIM-based spectral solar forcing in a 3D atmosphere-ocean coupled GCM Abstract We apply two reconstructed spectral solar forcing scenarios, one SIM (Spectral Irradiance Monitor) based, the other the SATIRE (Spectral And Total Irradiance REconstruction) modeled, as inputs…

Sun-Cloud-Ocean Update

Guest essay by Mike Jonas “so much to say…so little time.” – Roy Spencer I have at last found the time for the next step in my Sun-Cloud-Ocean calculations. But first, I would like to thank everyone who commented on my previous article. Some are addressed directly below, and all comments (well, most) were useful.…

New mechanism proposed that describes all solar eruptions

From NASA/GODDARD SPACE FLIGHT CENTER and the “solar eruptions are still a bigger threat to humanity than global warming” department. Scientists propose mechanism to describe solar eruptions of all sizes From long, tapered jets to massive explosions of solar material and energy, eruptions on the sun come in many shapes and sizes. Since they erupt at…

Robust relationship between solar wind speed and North Atlantic Oscillation discovered

Interdisciplinary studies reveal relationship between solar activity and climate change INSTITUTE OF ATMOSPHERIC PHYSICS, CHINESE ACADEMY OF SCIENCES The solar flux is considered the fundamental energy source of earth’s climate system on long time scales. In recent decades, some studies have noted that the tiny variations in solar activity could be amplified by the nonlinear…

Current Weak Solar Cycle Could Reduce Global Temperatures By Half A Degree

From ​the Swiss National Science Foundation (SNSF) Sun’s impact on climate change quantified for first time For the first time, model calculations show a plausible way that fluctuations in solar activity could have a tangible impact on the climate. Studies funded by the Swiss National Science Foundation expect human-induced global warming to tail off slightly over…

Solar Slump: The Sun has been blank for two weeks straight

Over the weekend, we reviewed the state of the solar data for March 2017. Now, there’s a two week straight lack of sunspots, the longest stretch since 2010. Overview The sun is currently blank with no visible sunspots and this is the 14th straight day with a blank look which is the longest such stretch…

Solar Update March 2017 – still slumping

Guest essay by David Archibald Our divination of solar parameters is aimed to elucidating two things – the length of Solar Cycle 24 and the amplitude of Solar Cycle 25. Figure 1: F10.7 Flux from 2014 The F10.7 flux was exhibiting high volatility up to the beginning of 2015 after which it entered a disciplined…
