In fact, according to National Geographic editor Dennis Dimick, “people have a hard time understanding when we talk about climate change. » His views changed dramatically after the EIS and now he is one of the leading advocates for recognizing human-caused climate change. Additionally, scientists have provided further evidence of the increase in greenhouse gases in the atmosphere that leads to climate change. They can drill holes in glaciers and remove a core. which consists of layers of ice accumulated millions of years ago. These layers provide information about ancient air bubbles trapped in the ice that reveal past temperatures and the carbon dioxide content of the air. Today, carbon dioxide levels are 40% higher. than any natural level in the past and are increasing at more than 100 times the highest natural rate recorded. Balog highlights how the physics and chemistry of the air are changing, leading to more natural disasters such as hurricanes and tornadoes. Although on paper the temperature changes may not seem too drastic, it only takes a small change to cause massive changes to the environment, in the same way that small amounts of steroids can have a massive effect on the environment. human body. These changes will continue to destroy our environment unless humans collectively make efforts to reduce this climate.
