WebAs 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...
WebFORCING: Something acting upon Earth's climate that causes a change in how energy flows through it (such as long-lasting, heat-trapping gases - also known as greenhouse gases). These gases slow outgoing heat in the atmosphere and cause the planet to warm.
WebThis website provides a high-level overview of some of the known causes, effects and indications of global climate change: Evidence. 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.
WebApr 12, 2024 · 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.

Climate change is a long-term change in the average weather patterns that have come to define Earth’s local, regional and global climates. These changes have a broad range of observed effects that are synonymous with the term.
WebCauses of climate change. Drivers of climate change from 1850–1900 to 2010–2019. There was no significant contribution from internal variability or solar and volcanic drivers. The scientific community has been investigating the causes of climate change for decades.
WebOct 19, 2023 · The cause of current climate change is largely human activity, like burning fossil fuels, like natural gas, oil, and coal. Burning these materials releases what are called greenhouse gases into Earth’s atmosphere. There, these gases trap heat from the sun’s rays inside the atmosphere causing Earth’s average temperature to rise.
WebEvidence - NASA Science. There is unequivocal evidence that Earth is warming at an unprecedented rate. Human activity is the principal cause. En español. Takeaways. While Earth’s climate has changed throughout its history, the current warming is happening at a rate not seen in the past 10,000 years.
WebWhat 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
