What planet does these reporters come from?
Over the very long term, variations in Earth’s orbit that shape where and when sunlight reaches the planet are the main cause of ice ages, but this doesn’t apply to our current situation. It’s true that the Sun has produced more sunspots in recent decades than it did in the early 1800s. However, this mainly reflects an increase in the ultraviolet range of sunlight, which is only a tiny part of the solar spectrum.
In fact, the total solar energy reaching Earth changes very little over time. Across the 11-year solar cycle, it varies by less than 0.1%, and even across the period since the little ice age chill of 1750, solar output climbed no more than about 0.12%, according to the 2007 report from the Intergovernmental Panel on Climate Change. Subsequent estimates by Judith Lean of the Naval Research Laboratory and others have pegged the solar contribution to 20th-century warming at 10% or less. And a recent analysis of solar trends suggests that – over the last few decades – the sun has actually contributed a slight cooling effect, rather than accounting for any of the observed warming.
