WebThe Causes of Climate Change. Human activities are driving the global warming trend observed since the mid-20th century. The greenhouse effect is essential to life on Earth, but human-made emissions in the atmosphere are trapping and slowing heat loss to space. Five key greenhouse gases are carbon dioxide, nitrous oxide, methane ... WebApr 7, 2024 · Climate change, it should be obvious by now, is happening. And as that chart of CO2 concentration shows, the correlation with economic growth powered by the burning of fossil fuels – energy sources which emit into the atmosphere CO2 which has been buried underground for millions of years – leaves little doubt as to where this CO2 came from.
