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.
Causes and Effects of Climate Change. Fossil fuels – coal, oil and gas – are by far the largest contributor to global climate change, accounting for over 75 per cent of global greenhouse...
Since the Industrial Revolution, human activities have released large amounts of carbon dioxide and other greenhouse gases into the atmosphere, which has changed the earth’s climate. Natural processes, such as changes in the sun's energy and volcanic eruptions, also affect the earth's climate.
Human activity since the Industrial Revolution (about 1750), mainly extracting and burning fossil fuels (coal, oil, and natural gas), has increased the amount of greenhouse gases in the atmosphere, resulting in a radiative imbalance.
Human-driven causes of climate change. Scientists agree that human activity is the primary driver of what we’re seeing now worldwide. (This type of climate change is sometimes referred to as...
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. A concise discussion of the primary climate change causes on our planet. Effects. A look at some of the likely future effects of climate change, including U.S. regional effects. Vital Signs.
Brief descriptions of some of the key scientific observations that our planet is undergoing abrupt climate change. Causes. A concise discussion of the primary climate change causes on our planet. Effects. A look at some of the likely future effects of climate change, including U.S. regional effects. Vital Signs.
Human activity is the principal cause. Earth-orbiting satellites and new technologies have helped scientists see the big picture, collecting many different types of information about our planet and its climate all over the world.
What Are the Effects of Climate Change? 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. more
