The luxury of precise and worldwide climate data has not existed long enough to properly settle the dispute of whether this shift of climate is a recurring trend or a snowballing disaster caused by CO2 excess, and will require more time to settle.
Modern-day society is not environmentally-friendly, and that is something that should definitely be changed using our technology and resources. My disagreement with the environmentalist point of view is that it is 100% our fault that climate is changing, and also with the way that it sometimes gets overpoliticized.
