This article, the second in a series on climate change, explores the science behind its causes, emphasizing human activity as the driver of this crisis. Following political actions that downplay climate science, it underscores the consensus among scientists that climate change is real and exacerbated by greenhouse gases, notably carbon dioxide, which has surged from 280 ppm to over 430 ppm since the 1800s. The consequences include rising global temperatures, severe weather shifts, and threats to human survival, necessitating urgent changes in behavior and policy toward the climate crisis.
Climate change is an environmental crisis created by greenhouse gases released into the atmosphere by human industrial activity, requiring humans to change their behavior for survival.
The concentration of carbon dioxide in the atmosphere has increased from about 280 parts per million in the 1800s to more than 430 parts per million today.
