Human Influence On The Earth's Climate by Bingchao Lin https://padlet.com/bilin3/a9lpqwlmfgjcklvc en-us 2022-01-10 17:03:14 UTC 2026-01-16 21:51:44 UTC hello@padlet.com https://padlet.net/icons/png/1f30e.png Introduction to Climate Change bilin3 https://padlet.com/bilin3/a9lpqwlmfgjcklvc/wish/1984318452
Climate change refers to changes in the climate over the periods of Earth. Climate change is caused by increasing greenhouse gases in the atmosphere of the Earth. 

Increasing greenhouse gases in the Earth’s atmosphere are warming the Earth and the Oceans. This results in rising sea levels, more wildfires, drought, changes in storm patterns, rainfall, melting snow, and ice.

The Earth's climate has changed throughout history, most of the changes in the Earth's climate in the past 650,000 years are from the small changes in Earth's orbit that change the amount of solar energy our planet receives.

The warming trend starting from the mid-20th century to now however has shown significant growth as the Earth's climate is increasing at a rate that is unprecedented over thousands of years. It is undeniable that the result of human activity since the mid-20th century to its current date has an influence on climate change.

Human activity releases tons of greenhouse gases chemicals that contribute to climate change such as carbon dioxide, a greenhouse gas that absorbs and radiates heat into the Earth's atmosphere, warming the Earth and causing climate change. 

Human activity deforestation plays a major part in climate change, tree help controls the temperature of the climate by absorbing carbon dioxide from the atmosphere, when trees are cut down the carbon dioxide that was absorbed by the trees are released back into the atmosphere, contributing to the greenhouse effect. According to NASA, human activities like land-use changes, burning fossil fuels as well as deforestation have increased the atmospheric Co2 concentration by 48% since the beginning of the Industrial Revolution.

Another major chemical that contributes to climate change is Methane, a greenhouse gas that can be produced through natural sources and human activities. Although methane is much less abundant in the atmosphere, it is also a war more active greenhouse gas compared to carbon dioxide. Human activity like increasing livestock farming can produce large amounts of methane as major livestock like cows and sheep produce methane when they digest their food.

One graph is showing the human-influenced factor and the other graph is showing the natural factors of temperature anomaly.

The graphs show data all the way from the 1880s to the present. The natural factor graph shows a steady increase in temperature. The human-influenced factor graph however showed an exponential growth starting from the 1920s.

The all factors graph below both human-influenced and natural factor graph shows that human-influenced factors have a greater impact than natural factors on temperature anomaly.

The planet's average surface temperature has risen about 1.18 degrees Celsius, or 2.12 degrees Fahrenheit since the late 19th century. Increased carbon dioxide emissions into the atmosphere however lead to the seven most recent years being the warmest years ever.]]> 2022-01-14 03:09:15 UTC https://padlet.com/bilin3/a9lpqwlmfgjcklvc/wish/1991583575
