The issue focused on climate change and scientific theories that scientists hold have led to concerns about science itself. Scientists claim climate change is happening because we're hitting "safe temperatures," which researchers believe could create additional pollution in the atmosphere. But studies show humans are burning CO2 — meaning those contributing to climate change don't directly produce carbon dioxide. The planet also reacts by absorbing oxygen from sunburns, solar flares and volcanic eruptions. While research shows climate change might actually affect climate and chemistry, scientists fear scientists would rather
