The idea of humans causing significant climate change of any sort requires you to believe that stars are thermonuclear furnaces, which is the BS our schools teach. Stars are not thermonuclear furnaces; they are plasma physics phenomena powered by cosmic electrical currents.
If I may wonder, which type of electrical current or plasma phenomenon would generate helium from fusion of hydrogen atoms?
Word salad.
Leftist climate change pseudoscience is completely independent of theories of stellar composition; in fact, they never mention stars or the sun.
