evidence: The most recent solar cycle was relatively quiet, leading to a lot of fearmongering over an impending Grand Solar Minimum, a longer period of time spanning several cycles where even the maximums are subdued. Reports suggested global temperatures would plummet, producing a mini ice age. NASA gave this idea a sound drubbing earlier this year. "The warming caused by the greenhouse gas emissions from the human burning of fossil fuels is six times greater than the possible decades-long cooling from a prolonged Grand Solar Minimum," wrote the NASA Global Climate Change team in February. [...] So, the solar minimum we're about to enter doesn't look particularly unusual, according to the NOAA and NASA, and we can expect a similar intensity to the previous cycle, they noted in their prediction.
