What Is Causing Climate Change To Happen – Climate change is real and we are surrounded by evidence. Although Earth’s climate change is nothing new, it is clearly having a devastating effect on many people, places and wildlife. If you want to know what climate change is and why, keep reading to learn more about the causes, consequences, and effective solutions to stop it. .
You may have heard the terms climate change and global warming used interchangeably. Because they both describe how the world is changing. While global warming focuses on an increase in global temperatures, climate change refers to changes in rainfall, wind patterns, and temperature over a period of time. Changes in climate can occur over years, decades, or millions of years.

What Is Causing Climate Change To Happen
Climate change has been around for as long as the earth has existed. Earth’s climate fluctuates and remains constant for measurable periods of time. This is reflected in the natural cycles of winter and summer. Before human factors began to change the world’s climate, there were five main factors that interacted to change the climate. These include five: [1]
Climate Change: Causes, Impacts, And Solutions
According to the American Association for the Advancement of Science, “The scientific evidence is clear: global climate change caused by human activities is already occurring, and it is growing as a threat to the crowd.” [2]
Greenhouse gases play an important role in the global climate. When the earth hits the sun’s rays, some of the energy is absorbed and the rest of the energy and heat is reflected back into the atmosphere. Greenhouse gases in the atmosphere trap visible energy and return it to Earth, resulting in global warming. Various gases play this role, including:[3]
While some of these greenhouse gases, such as water vapor, are naturally occurring, others, such as CFCs, are synthetic. CO2 is released into the atmosphere from natural and man-made sources and is one of the main contributors to climate change. CO2 is rising at an alarming rate and can remain in the Earth’s atmosphere for thousands of years if it is not absorbed by the oceans, land, trees and other sources. [4] However, while CO2 production has continued to increase, the Earth’s natural resources have also decreased in their ability to absorb it. This is happening in many ways because of the loss of Eid resources from things like deforestation. Some studies predict that plants and soil will absorb less CO2 as food continues to warm – a faster rate of climate change. [5]
The sun’s activity, as mentioned above, plays a role in the Earth’s climate. As the Sun goes through natural cycles of increasing and decreasing the amount of energy it provides to Earth, the Sun’s role in global warming or climate change may not be significant. the weather Since scientists began measuring the Sun’s energy hitting our atmosphere, no increase has been measurable.[6]
Climate Explained: How Much Of Climate Change Is Natural? How Much Is Man Made?
There are many important ways in which agriculture affects climate change. Agriculture accounts for most of the world’s greenhouse gas emissions, from deforestation to transportation and livestock in places like the Amazon to support agricultural operations around the world However, agriculture is one sector that is making great efforts to become sustainable. As productivity increases, less carbon is needed to produce food. Agriculture can act as a carbon sequester, ultimately sequestering as much CO2 as it emits. [7]
Deforestation and climate change go hand in hand. Not only does forest change increase through wildfires and other natural disasters, but deforestation is also a major contributor to global warming. According to the Earth Day Network, deforestation is the second largest source of greenhouse gases. [8] Many people and organizations fighting climate change consider deforestation as one of the most important, if not the most important, problems that slow and prevent climate change. [9]
According to the Environmental Protection Agency, the biggest contributor to climate change in the United States is the burning of fossil fuels for electricity, heat and transportation. Among these sources, transportation in the form of cars, trucks, ships, trains, and airplanes emits large amounts of CO2—which increases global warming and is a major cause. of climate change. [10]
Although related to many of the agricultural and deforestation issues we touched on earlier, livestock such as cattle, sheep, pigs and chickens play a major role in change. measuring the weather. According to a study, “Livestock and Climate Change,” livestock worldwide is responsible for 51% of global greenhouse gas emissions. [11]
Why Doesn’t Everyone Believe Humans Are Causing Climate Change?
From melting glaciers to hurricanes, people everywhere are beginning to realize the real impact of climate change. While some countries around the world are taking steps like the Paris Climate Agreement, others are continuing business as usual – burning millions of carbon dioxide into the atmosphere. each year. While the long-term effects remain to be seen, in the meantime, climate change continues to cause extreme weather and security and economic problems on a global scale.
Climate change is the biggest impact of climate change for the average person. One reason for this is the financial impact that adverse events can cause. Currently in 2019 in the United States, there are six major disasters, the cost of which is more than $ 1 billion. [12] According to the National Climate Assessment, extreme weather events will continue to increase in frequency and intensity as climate change continues. [13] The worst-case scenarios related to climate change include:
In 2014, the US Department of Defense issued a report indicating that climate change is a serious threat to the country. According to former Secretary of Defense Chuck Hagel, “Increasing global temperatures, changing precipitation patterns, rising sea levels, and extreme weather events will intensify the challenges of the global instability, hunger, poverty, and conflict.” [14]
In addition, climate change can cause economic problems in many parts of the world. According to some estimates, the United States already spends about $240 billion annually as a result of human-caused climate change, and the costs will be much higher. measures. [15] However, when you consider the huge costs of losing natural resources such as clean air and water, it is difficult to put an exact number on the real costs of changing to the weather

The long-term effects of climate change will be devastating to the planet and everyone who lives on it. If the world continues on its current path, we will continue to see the consequences in everyday life.
Climate affects people’s health in many ways. Depending on age, location and economic status, climate change affects the health of many and can affect millions. According to the Centers for Disease Control and Prevention, the health risks associated with climate change include: [16]
Ecosystems are webs of organisms that help support plant species and biodiversity. Climate change is changing weather patterns and depleting food supplies for plants and animals around the world, creating mass extinction events. Some studies estimate that up to 30% of plants and animals are at risk if global temperatures continue to rise. [17]
Climate change has a significant impact on food and water supplies. Climate change and rising temperatures will limit crop yields and increase demand for water. With food demand expected to increase by 70% by 2050, the problem will only increase. [18]
What Causes Climate Change? — Earth@home
Rising sea levels can have long-term effects on coastal cities and settlements. Rising ocean temperatures and melting ice sheets are a constant cause of global sea level rise. At current rates, the National Oceanic and Atmospheric Administration expects sea levels to rise about 8 inches by the year 2100, increasing flooding and loss of marine and wetland habitats. [19]
While contributing to sea level rise, the loss of sea ice presents unique challenges, including global warming and greenhouse gas emissions. The change in summer melting of the ice sheets covering Greenland and Antarctica has increased by about 30% since 1979.
The ocean is one of the main channels through which CO2 enters. Although the net seems good at first glance, human-caused CO2 emissions are pushing the world’s oceans to their limits and increasing acidification. A drop in ocean pH makes it difficult for fish to reproduce, and affects many of the ocean’s food cycles. [21]
Although the effects of climate change may be bleak, there is still hope. By acting quickly on climate change, we can’t see the worst effects. Likewise, millions of new jobs and billions of dollars can be created when the world uses clean energy solutions.
