Significant Differences (p < 0.001) in means of age and climate change beliefs between Global North and Global South

	Global North (N = 19,201)	Global South (N = 11,083)	Significant difference (*) between Global North and South
Age (mean years)	45.07	36.97	*
Concern over climate change (1-5 scale: 5=Extremely worried)	3.644	4.069	*
Perceived climate harm (1-4 scale: 4 = A great deal)	2.772	3.253	*
Personal experience with a major natural disaster in last three years (percentage answering “Yes”)	33.28%	53.35%	*
Belief in science and technology as a solution to climate change (1-5 scale: 5 = Strongly agree)	3.337	3.810	*

Note: N = 30,284 participants. Significant differences (p < 0.001) between Global North and Global South cohorts, according to (two-tailed) independent-samples Mann Whitney U-testing. Age (mean) higher in Global North, U = 20700.00, Z = 14.16, p = 0.000; concern over climate change, U = 3050.00, Z = −10.229, p = 0.000, perceived climate harm, U = 2000.00, Z = −11.68, p = 0.000, personal experience with major natural disaster, U = 3500.00, Z = −9.60, p = 0.000, science and technology as solution to climate change, U = 1850.00, Z = −11.89, p = 0.000, higher in Global South. Means (not mean ranks, on which tests are based) reported.
