Nov 22, 2019 · The gases primarily responsible for global warming include water vapor, carbon dioxide, methane, nitrous oxide and chlorofluorocarbons (CFCs). Humans produce them by burning fossil fuels and engaging in various agricultural and industrial activities.
6 days ago · This article provides an overview of the scientific background related to the subject of global warming. It considers the causes of rising near-surface air temperatures, the influencing factors, the process of climate research and forecasting, and the possible ecological and social impacts of rising temperatures.
The increased surface temperature caused by global warming leads to noticeable changes in our climate - not just in warmer land and ocean temperatures. Other changes to the environment include rising sea levels, shrinking glaciers and sea-ice, shifts in plant blooming times and an increase in extreme weather events.
Climate Change. The Causes of Climate Change. Human activities are driving the global warming trend observed since the mid-20th century. En español. Takeaways. The greenhouse effect is essential to life on Earth, but human-made emissions in the atmosphere are trapping and slowing heat loss to space.
