Regardless of causes and contributors (since Bit adamanetly refuses that the man-caused portion is part fo his question, only "climate change" is), DOES the climate of planet Earth change over time in any way?
Does the Climate of the Earth Change over Time? i.e. Is Climate Change (a changing climate over time due to any number fo factors) real?
Yes it's real, the climate changes, or no it's no real, the climate never changes?
