Global Warming How Is It Caused – What causes global warming? (How Climate Change Will Affect the World!) by Lyle Oplentisima | Source: Here on April 22, 2022
Global warming is a problem that has been increasing in importance for more than a decade. Everyone wants to know what causes global warming and how it affects our planet. It’s not just one thing – it’s a combination of factors, including human activity. Let’s dive into the science behind global warming and the effects of global climate change.
Global Warming How Is It Caused
The greenhouse effect is a natural process that keeps the Earth’s temperature at a level that supports life. The atmosphere absorbs sunlight and traps heat on the planet. This process allows plants, animals and humans to live. Greenhouse gases in the atmosphere consist mostly of water vapor, carbon dioxide and methane, with smaller amounts of nitrous oxide, ozone and fluorinated gases. These gases are critical to keeping our planet warm enough to support life.
How Much Would It Cost To End Climate Change? Get The Facts
Travel and transportation accounts for 14% of global greenhouse gas emissions. From the extraction of fossil fuels to the use of end products as fuel, travel and transportation contribute to global warming. Transportation is responsible for the largest amount of greenhouse gas in the world. The most common greenhouse gas emitted from transportation sources is carbon dioxide (CO2). In general, CO2 is produced when carbon-based materials such as coal or petroleum (such as gasoline) are burned. The amount of carbon dioxide emitted depends on how far you travel, how much energy your vehicle uses during your trip (fuel consumption), and how much energy is needed for other activities during your trip.
Industrialization is a set of social changes that occur when a society moves from primarily producing goods to producing services and goods. This type of change is mostly related to urbanization, and the development of new technologies such as cars and airplanes have contributed significantly to climate change.
Industrialization has contributed significantly to climate change by causing massive air pollution. These pollutants have damaged the ozone layer, which protects the earth’s surface from harmful ultraviolet rays from the sun. As a result, more heat is now trapped in the atmosphere, which leads to higher temperatures around the world – global warming – and the melting of the polar ice caps. The effects can already be seen in some parts of the world, for example, in 2019 alone we saw extreme heat waves across Europe and North America, and Greenland recorded its first tropical cyclone.
Deforestation is the cutting of trees, the loss of forested land. This is often the result of commercial mining. When people clear forests to make way for farms or cities, that is deforestation. Deforestation accelerates the problem of global warming (because plants are less able to absorb carbon dioxide), deprives wildlife of their natural habitat, and contributes to soil erosion. As more land is converted to farmland or cities, the amount of carbon remaining in the soil decreases and carbon dioxide is released into the atmosphere.

Sea level is rising, this is because seawater expands as it warms and melting ice adds to the water. Climate change causes changes in climate. Ice caps are melting faster than ever. . As the oceans continue to warm, weather events such as hurricanes become more frequent, fueling hurricanes with increased energy. As temperatures rise, wildfires increase as drier conditions create debris in western forests (and beyond). Smoke from those fires spreads across the country, affecting people living far from the fires.
Our planet’s climate is changing and we need to do something. The easiest and most effective step we can take is to plant trees. Despite what you may have heard, planting trees won’t stop the effects of global warming—in fact, forests are some of nature’s best carbon sinks.
You don’t have to wait until you’re older or more mature to help clean up the world in your own backyard. Seeds today are easy for anyone to start planting at home. As an added bonus, by starting a tree program in your community, you will not only be helping yourself, but generations! Global warming refers to the increase in average global temperature since the industrial revolution. Since 1880, the average global temperature has increased by one degree Celsius (1.8 degrees Fahrenheit). Global warming is an ongoing process; Scientists expect the average global temperature to rise by 0.3 to 0.7 degrees Celsius (0.54 to 1.26 degrees Fahrenheit) by 2035.
Some gases, such as carbon dioxide and methane, trap the sun’s heat in the earth’s atmosphere. These greenhouse gases (GHG) occur naturally in the atmosphere and help keep the Earth’s surface warm enough to support life. Without greenhouse gases, the average temperature on Earth would be zero degrees Fahrenheit, instead of today’s approximately 58.3 degrees Fahrenheit.

Human activity, especially the use of fossil fuels (ie coal, natural gas and oil) to power vehicles, factories and homes, releases carbon dioxide and other greenhouse gases into the atmosphere. Other activities, including deforestation (cutting down trees) and farming, produce greenhouse gases.
High concentrations of greenhouse gases in the atmosphere trap more heat on Earth, leading to anthropogenic (ie man-made) global warming. Climate scientists agree that human activity is the main cause of the global warming we are experiencing.
The terms climate change and global warming are often used interchangeably, but climate change generally refers to ongoing changes in the average climate (eg, temperature, precipitation, humidity, wind, atmospheric pressure, ocean temperature, etc.). Average global temperature rise of the Earth.
Climate change can refer to natural fluctuations in the Earth’s average temperature over geological time, between cold periods (known as ice ages) and warm periods (interglacials).
Climate Change Facts That You Need To Know
However, the climate change we are currently experiencing is caused by human activity (see question 2). Scientists believe that in the last 50 years, the Earth’s surface should have cooled slightly based on natural factors such as solar intensity and volcanic activity; Instead, the increase in fossil fuels has caused global warming – faster than at any time in the past 800,000 years.
A rise in average temperature due to human activity has many effects on the planet, including more intense and frequent droughts and storms, melting glaciers and ice sheets, rising sea levels, warming and ocean acidification (see question 8). People around the world are affected by climate change. Climate change can destroy crops and cause severe water shortages. Rising sea levels threaten low-lying islands and coastal cities. Warm and insect-borne diseases spread because their hosts move to new habitats that were previously too cold to survive.
Climate change poses a serious threat to the health and well-being of human societies, especially in communities that are resource-rich and ill-equipped to cope with the effects of a warming climate.
5. What does global warming have to do with extreme weather such as hurricanes, heat waves, droughts and hurricanes?

Global warming will increase the severity and likelihood of hurricanes, floods, wildfires, droughts and heat waves. During warmer climates, the atmosphere can collect, hold, and shed more water, changing precipitation patterns. Increased rainfall will help support agriculture, but increased rainfall is also a property of intense one-day storms, damaging infrastructure and causing loss of life in affected areas. Over the past few decades, the United States has experienced more heat waves and cold waves. Since the 1960s, the length of heat waves in many cities has increased to more than 40 days. Major US cities average more than six heat waves per year, compared to two heat waves in the 1960s. Global warming leads to higher sea surface temperatures because most of the heat in the earth’s atmosphere is absorbed by the oceans. Higher sea surface temperatures facilitate the formation of hurricanes. Due to anthropogenic warming, the amount of rain from hurricanes is predicted to increase, the size of hurricanes will increase, and the number of storms reaching categories 4 and 5 will increase.
It is difficult for researchers to associate certain weather conditions with global warming. However, climate scientists believe that higher average temperatures will make extreme weather more severe. The United States is witnessing an increase in the number of catastrophic weather and climate disasters due to coastal and river flooding (meaning that more people and infrastructure are affected in these areas). The chart below from the National Oceanic and Atmospheric Administration (NOAA) shows the number and impact of billion dollar disasters during the decade of 1980-2019.
