evidence: Without the greenhouse gas effect, surface temperatures would drop 33 degrees Celsius (59.4 degrees Fahrenheit), according to the World Meteorological Organization (WMO) — making the planet a frozen, uninhabitable place. [...] The report described increasing levels of greenhouse gases in the atmosphere resulting from human activities, as "a major driver of climate change". [...] "If an alternative theory of what is driving climate change rather than greenhouse gases would be supported by research and evidence, such work would be groundbreaking," said Benjamin Cook. "It would be Nobel Prize-level study. But we do not see this research."
