Which of these statements from the same article are true?

the effect is so small that it has very little impact on the weather and climate on Earth.

the number of sunspots (through association with active regions) may influence the climate

the net result is a heating of the Earth

so the net result is cooling

You obviously didn’t read it carefully. Go back and try again. If you still have problems, let me know.

Which of these statements from the same article are true?

Depends on what the article was referring to at the time. You lifted each of these statements totally out of their context.

"the effect is so small that it has very little impact on the weather and climate on Earth."

Here they are referring to the hotter regions on the Sun's surface which often accompany sunspots. Sunspots themselves are cooler than the surrounding solar surface. That's why they appear dark. The theorized climate relationship involves *magnetic* changes on the Sun. Not greater amounts of heat being produced by the Sun during sunspot outbreaks.

-------------------

"the number of sunspots (through association with active regions) may influence the climate"

Several mechanisms at play here. One involves the production of the greenhouse gas ozone (O3) in Earth's atmosphere via increased solar activity and increased ultra-violet radiation.

-------------------

"the net result is a heating of the Earth"

This would be the case if there were more high-level, Sirius-type clouds being produced via galactic cosmic ray interactions with atmospheric particles (in our atmosphere).

-------------------

"so the net result is cooling"

This would be the case if more low-level, thick, sunlight-blocking cumulus-type clouds are being produced via galactic cosmic ray interactions with atmospheric particles (in our atmosphere). The researchers that I linked to believe the solar activity-cosmic ray-cloud formation-Earth climate connection involves the production of these types of clouds (thick, low-level sunlight-blocking clouds) And so when the Sun is magnetically active (around sunspot cycle peaks), less of these cooling clouds form, more sunlight reaches the Earth and the surface warms *naturally*.
