Yup, global climate change brought about primarily through human activities imho. We have increased the carbon dioxide level above 400 parts per million. The last time this happened the world was a much different place and very inhospitable to humans. From all that I have heard and read on the subject we are heading towards a four or five degree centigrade rise in temperature and should be taking emergency steps to head off this possibility.

I agree that radiation from electronic devices would be a good thing to research more solutions to as well. My grandfather passed away from cancer that they think was caused from working around high voltage and dielectric materials (PVC) so I know this can cause issues. It would be good to find healthier solutions for using these mobile computers.

My guess is that unless we fix the climate issue soon, most of us will not be too worried about EV radiation because estimates of the carrying capacity of the earth could drop to a billion people if the temperature rises this high. The way things are going, this could happen faster than developing cancer for most of us. See this article for more on these facts: Earth risks tipping into 'hothouse' state: study
