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.
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.
Modern global warming is the result of an increase in magnitude of the so-called greenhouse effect, a warming of Earth’s surface and lower atmosphere caused by the presence of water vapour, carbon dioxide, methane, nitrous oxides, and other greenhouse gases.
Vital Signs of the Planet: Global Climate Change and Global Warming. What is the “greenhouse effect”? What is causing it? Are humans to blame? What does solar irradiance have to do with it? Answers here.
Causes of global warming, explained. Human activity is driving climate change, including global temperature rise. January 17, 2019. • 4 min read. The average temperature of the Earth is...
As greenhouse gas emissions blanket the Earth, they trap the sun’s heat. This leads to global warming and climate change. The world is now warming faster than at any point in recorded...
The effects of human-caused global warming are happening now, are irreversible for people alive today, and will worsen as long as humans add greenhouse gases to the atmosphere. We already see effects scientists predicted, such as the loss of sea ice, melting glaciers and ice sheets, sea level rise, and more intense heat waves.
Global warming is the long-term heating of Earth’s surface observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere.
How do we know global warming is not because of the sun or volcanoes? The sun is the ultimate source of energy in Earth’s climate system, so it’s a natural candidate for causing climate...
The effects of human-caused global warming are happening now, are irreversible on the timescale of people alive today, and will worsen in the decades to come.
