Science leaves a lot of questions open, tons of variables: we know that an overall warmer climate is bad for ppl. Warm objects radiate electromagnetic waves, warmer = shorter wavelength. Sun emits radiation that reaches the earth. Earth temp = energy from sun outgoing infrared radiation. Greenhouse gases: h20(v), co2, ch4, ozone, no2, artificial cfcs absorbs infrared radiation, ozone holes. Human activities directly increased these gases (anthropogenic greenhouse gases) excludes h20(v) 400pp was a milestone in a negative sense.
