A common argument against global warming and climate change is that it is just the sun's heat, nothing more. But, scientific research and measurements have shown that over the last 35 years the sun has shown a slight cooling trend; however global temperatures have been increasing. So the global increase in temperature cannot be blamed on solar flares or sunspots, but some other cause, like the increase of CO2 emissions.
Another ignorant belief is that the ocean acidification being caused by rises in CO2 is not harmful, it's just happening. As ocean waters absorb CO2 they become more acidic. Ocean life can be sensitive to slight changes in pH levels, and any drop in pH is an increase in acidity, even in an alkaline environment. An increased level of acidity means hazardous habitats for marine life. Corals and the shells can have a struggle to form and grow.The acidification can also cause small, bottom of the food chain organisms' population can severely decrease, resulting in the collapse of food chains.
