Climate change / Grand solar minimum

[16coresCasual]

Basically, there's a THEORY that our sun affects our climate the most, that man-made change is insignificant and that we are slowly going into a new ice age. Supposedly it's all about solar cycles and she developed a model that can predict these things. What do you guys think? I'm adding two long videos that go into detail .

It can be true but there's one thing for sure - shit is going to happen. All drastic climate changes can affect lower amount of crops and it can give starvation then war.

It's a bullshit theory. As it's already proven in various studies that delve into thousands of years of data as in ice cores - it's mostly the rise of CO2 level that precedes the rise in temperatures and correlates with it. The cyclical change behind inclination of the Earth's axis that changes over millennia is crucial though (Milutin Milankovitch cycle) - as well as changes in orbital eccentrity. But our anthropogenic activity also alters Earth's tilt to some extent.

Changes in orbital eccentricity affect the Earth-sun distance. Currently, a difference of only 3 percent (5 million kilometers) exists between closest approach (perihelion), which occurs on or about January 3, and furthest departure (aphelion), which occurs on or about July 4. This difference in distance amounts to about a 6 percent increase in incoming solar radiation (insolation) from July to January. The shape of the Earth’s orbit changes from being elliptical (high eccentricity) to being nearly circular (low eccentricity) in a cycle that takes between 90,000 and 100,000 years. When the orbit is highly elliptical, the amount of insolation received at perihelion would be on the order of 20 to 30 percent greater than at aphelion, resulting in a substantially different climate from what we experience today.

Changes to global temperatures are brought about by changes in the Earth's axial tilt but it's a seperate phenomena against what we're facing now short-term.
