Answer 1

Hint: Global warming is the long-term warming of Earth's climate system that has been observed since the pre-industrial era (between $1850$ and $1900$) as a result of human activities, mainly fossil fuel burning, which raises heat-trapping greenhouse gas levels in the atmosphere.

Complete answer:
Climate change includes the long-term increase in global temperatures, which is referred to as global warming. Increased greenhouse gas concentrations in the environment, mostly from human activities such as burning fossil fuels, deforestation, and farming, cause it.
Hydrocarbons, which are present in fossil fuels such as crude oil, natural gas, and coal, are organic compounds made up solely of hydrogen and carbon atoms. They're divided into five different families or homologous series (alkanes, alkenes, alkynes, cycloalkanes, alkadiene). A homologous sequence of hydrocarbons has the same general formula, chemical, and physical properties. The alkene family of hydrocarbons, which includes methane, ethane, propane, and butane, has the most identifiable structure, with carbon-carbon single bonds.
Carbon dioxide, as well as other greenhouse gases, are released during the combustion of hydrocarbon fuels, contributing to emissions and climate change. $C{O}_2$ is an unavoidable by-product of hydrocarbon combustion, unlike impurities that cause by-product pollution from fossil fuels. The length of a fuel's hydrocarbon chain and the complexity of its hydrocarbon molecules determine its energy density and $C{O}_2$-footprint.
As methane is released into the atmosphere, it responds in a number of dangerous ways. For one thing, methane is primarily removed from the atmosphere by oxidation, which results in the formation of water vapour and carbon dioxide. As a result, not only does methane directly contribute to global warming, but it also indirectly contributes to global warming through the release of carbon dioxide.

Note:
Methane also leads to the formation of ozone, which lowers air quality and causes a variety of health problems in animals, as well as premature human deaths and lower crop yields. Reduced methane levels in the atmosphere would eventually mitigate these impacts.
