evidence: "In our paper, we show, using the best available observations from the [Clouds and the Earth’s Radiant Energy System] platform, that the warming of the last 24 years was entirely caused by the observed decrease of Earth’s albedo and not by increasing greenhouse gas concentrations as claimed by the IPCC." [...] In response to the question "Is the Sun causing global warming?" on its website, NASA states, "No. The Sun can influence Earth’s climate, but it isn’t responsible for the warming trend we’ve seen over recent decades. "The Sun is a giver of life; it helps keep the planet warm enough for us to survive. We know subtle changes in Earth’s orbit around the Sun are responsible for the comings and goings of the ice ages. But the warming we’ve seen in recent decades is too rapid to be linked to changes in Earth’s orbit and too large to be caused by solar activity."
