evidence: What happens if the next solar cycle becomes less active? Will we enter into a new ice age? [...] In more depth, scientists know that even a prolonged Grand Solar Minimum would only serve to offset a few years of warming caused by human activities. In other words, warming caused by the greenhouse gas emissions from the human burning of fossil fuels is 6 times greater than the possible decades-long cooling from a prolonged Grand Solar Minimum. Even if a Grand Solar Minimum were to last for a century, global temperatures would still continue to warm. Because the Sun is not the only factor affecting global temperatures on Earth.
