The science of global warming is a complex topic, with many different facets. The history of global warming is a brief timeline of the major environmental changes on Earth. The timeline begins in the late 1800s with the discovery of natural greenhouse gases and continues to the present day.
Global warming is the increase in the average temperature of Earth’s atmosphere and oceans gases, such as carbon dioxide, methane, nitrous oxide, and water vapour. . It has been proven that the climate change we are seeing today is due to human activities
In 1859, John Tyndall discovered that water vapour and carbon dioxide could trap heat from escaping Earth’s atmosphere, meaning they act as natural “greenhouse” gases. This was before humans significantly impacted climate change through industrialization and deforestation. The pre-industrial period began in 1750 with a small increase in temperature. The industrial period began at the end of the 19th century and saw a major industrial temperature increase. The post-period has seen an even greater increase in temperature, which continues to increase to this day. In 1896, Svante Arrhenius calculated how much CO2 would be needed to raise global temperatures by 5 degrees Celsius (9 degrees Fahrenheit) if it doubled in concentration over a century or so – what we now know as “global warming.”
Greenhouse Gases: Greenhouse Gases are gases that trap heat in the earth’s atmosphere. They are made up of water vapour (H2O), carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) among others
Carbon Dioxide is the most important of all greenhouse gases. It is created by burning fossil fuels and natural gas, and it also comes from other sources like deforestation, animal agriculture, and landfills.
The UN has warned that global warming can lead to the extinction of up to one-third of all plant and animal species. In order for us to reduce the impact we have on our environment, it is important that we take steps at home.
