The Solar Storm That Nearly Sparked A Nuclear Confrontation

On May 23rd, 1967, a solar storm took place that was so powerful, it jammed radar and radio communications in polar regions and the US Air Force actually began to…

X-Class Solar Flare

Even though the responsible sunspot was located behind the edge of the sun, enough radiation reached our planet to cause a strong shortwave radio blackout.

How Climatologists Forgot the Sun Was Shining: Your Questions Answered

Their error was so large that, after correction, the near-certainty of future global warming large enough to be catastrophic vanishes, and the tawdry notion of “climate emergency” with it.

Massive X-CLASS SOLAR FLARE Hurls a CME Towards Earth

Via SpaceWeather.com Earth-orbiting satellites have just detected an X1.3-class solar flare (March 30 @ 1737 UT). The source is active sunspot AR2975–the same sunspot that has already hurled at least two CMEs toward…

Group Sunspot Numbers: A New Reconstruction of Sunspot Activity Variations from Historical Sunspot Records Using Algorithms from Machine Learning

Indeed we think that this paper is very important on various fronts, including even the rather clear and revisionist attempts by several activists during the last 10 years or more…

Solar Variations Controversy

The impact of solar variations on the climate is uncertain and subject to substantial debate. However, you would not infer from the IPCC assessment reports that there is debate or…

Leif Svalgaard Responds to Willie Soon

To my eye there is no difference between our reconstruction and theirs [based on Machine Learning], except that we have error bars and they don’t. It is amazing how people’s…

Studying the Role of the Sun on Climate

Willie Soon, astrophysicist and aerospace engineer takes the stage at the 14th International Conference on Climate Change to discuss the role of the sun on climate change.

How the Sun Controls Arctic Ice and Temperatures part 3

Part 3 on controls on Arctic sea ice. Although sunspot cycles do not add enough energy to explain the Arctic’s warming, the sun and sunspot cycles do explain redistribution of…

Solar Update September, 2021

This figure also shows a flat trend through the 1970s cooling period followed by a 40 year long downtrend in activity. Whatever solar processes caused the Modern Warm Period and…

Challenging UN, Study Finds Sun—not CO2—May Be Behind Global Warming

Climate scientist Dr. Ronan Connolly, Dr. Willie Soon and 21 other scientists claim the conclusions of the latest “code red” IPCC climate report are strongly dependent on the authors’ narrow…

Can we predict long-term solar variability?

This post is a result of an online conversation with Dr. Leif Svalgaard, a research physicist at Stanford University. Leif knows a great deal about the Sun and solar variability…

A New Space Instrument Captures Its First Solar Eruption

Solar Orbiter has already taken the closest picture of the Sun to date, and it will only get closer. Solar Orbiter’s official mission begins in November, when SoloHI and the…

Scientists use AI to predict sunspot cycles

For the first time, scientists have used artificial intelligence not only to predict sunspots but also to correct the incomplete record of past sunspot activity.

New study ties solar variability to the onset of decadal La Nina events

The paper does not delve into what physical connection between the Sun and Earth could be responsible for the correlation, but the authors note that there are several possibilities that…

No Mention Of CO2: New Study Shows African Climate Variability Strongly Linked To Natural Cycles

A new study analyzes patterns of natural rainfall variability and can provide crucial assistance to African countries in seasonal rainfall forecasting for agriculture and protection against droughts & heavy rains.

Observations Around Solar System With Parker Solar Probe’s 7th Solar Encounter

During Parker Solar Probe’s seventh swing by the Sun, culminating in its closest solar approach, or perihelion, on Jan. 17, 2021, celestial geometry posed a special opportunity. The configuration of…

NASA Missions Make Unprecedented Map of Sun’s Magnetic Field

A major goal of heliophysics – the science of the Sun’s influence on space, including planetary atmospheres – is to predict space weather, which often begins on the Sun but…

Exploring the Solar Wind With A New View of Small Sun Structures

Scientists have combined NASA data and cutting-edge image processing to gain new insight into the solar structures that create the Sun’s flow of high-speed solar wind, detailed in new research…

Secrets Behind Sunquakes Could Lurk Beneath the Solar Surface

A secret behind the workings of sunquakes – seismic activity on the Sun during solar flares – might be hidden beneath the solar surface.

Huge sunspot may launch solar flares toward Earth in the next two weeks

One of the biggest sunspots in years is emerging on the sun today. Hours ago it produced a C-class solar flare and a minor radio blackout over the Indian Ocean.…
