No dude, rapid change in climate is directly tied to human activity. You should have read the article you posted:
"The radiation output of the Sun does fluctuate over the course of its 11-year solar cycle. But the change is only about one-tenth of 1 percent—not substantial enough to affect Earth’s climate in dramatic ways, and certainly not enough to be the sole culprit of our planet’s current warming trend, scientists say."
"As for Abdussamatov’s claim that solar fluctuations are causing Earth’s current global warming, Charles Long, a climate physicist at Pacific Northwest National Laboratories in Washington, says the idea is nonsense.
“That’s nuts,” Long said in a telephone interview. “It doesn’t make physical sense that that’s the case.”
In 2005, Long’s team published a study in the journal Science showing that Earth experienced a period of “solar global dimming” from 1960 to 1990, during which time solar radiation hitting our planet’s surface decreased. Then from the mid-1990’s onward, the trend reversed and Earth experienced a “solar brightening.”
These changes were not likely driven by fluctuations in the output of the Sun, Long explained, but rather increases in atmospheric clouds or aerosols that reflected solar radiation back into space."
