Global Warming The average global temperature of the Earth has risen an astonishing 1.4 degrees Fahrenheit since 1880. This may not seem like a big increase, but it actually is. In fact, 14 of the hottest years on record have been in the past 15 years. So what is the cause of this global warming? The main cause of global warming is the increasing concentration of greenhouse gases in the Earth’s atmosphere. Some greenhouse gases consist of water vapor, CO2, methane, and nitrous oxide.
When all of these gases are collected into the ‘lower environment,’ its makes something like a cover that makes it very easy for the hot radiations of the sun to earth to restrict its escape back to space. This whole process is known as the greenhouse effect. These gases in the Earth’s atmosphere trap hot radiations and keep Earth’s temperature increasing.
The level of greenhouse gases also increase. The level of greenhouse gases increases because of many human activities.
These activities include but are not limited to burning trees, burning fossil fuels, electric lighting, refrigerator, stove, air conditioning, and many other electric machines. These practices tend to release a rather high percentage of carbon dioxide and other greenhouse gases into the atmosphere causing Earth’s temperature to increase. This increasingly higher temperature on Earth causes Earth’s water to evaporate into the atmosphere faster which causes more water vapor. Water vapor again absorbs heat which in turn makes the Earth’s atmosphere warmer. Global warming has changed and will continue to change many of Earth’s natural processes such as rainfall patterns, rising sea level, the length of seasons, and much more.
Global warming is something powerful that affects all our lives actively, so we must do what we can to stop it.
