Yes, climate change is real. This finding is based on the consensus of a climate science community that is educated in these matters and have reached this determination based on the scientific process. The only people who say climate change is not real is business leaders who would lose money due to environmental regulations.
Scientists all over the world have facts and data that support climate change. Water temperatures have riser, glaciers are receding, the ice caps are melting. All this supports climate change. The real question is how much of the change was inevitable as a part of the natural climate changes Earth goes through and how much is due to human causes, and if the damage done by humans is reversible.
Yes, climate change is real and anyone who questions it should really examine where they get their information. Evidence of climate change is all around us: rising water levels, melting ice in the Arctic, increasing temperatures, violent storms. It is extremely difficult to find any way to deny the existence of climate change and very dangerous to do so.
Climate change is not real, because there is not enough data that the world is warming, permanently. The world goes through swings of warm and cold. That's how glaciers formed during the ice ages. Climate change is made up by scientists who want to impose socialism on the rest of the world.
