Climate Change Causes Effects and Solutions - Description
Dear readers, here we are offering Climate Change Causes Effects and Solutions PDF to all of you. Climate Change is one of the biggest problem that we are facing now days. Before understanding climate change, it is necessary to understand what is climate? Climate generally refers to the average weather in a given area over a long period of time. Scientists who study the earth tell that the temperature of the earth is continuously increasing. Earth’s temperature has increased by 1 degree Fahrenheit in the last 100 years.
This change in the Earth’s temperature may be very small in number, but any such change can have a big impact on mankind. Some of the effects of climate change are still being felt today. Due to the increase in the temperature of the earth, glaciers are melting and the water level of the oceans is increasing, as a result, the risk of natural disasters and drowning of some islands has also increased. climate change causes effects and solutions pdf will give a detailed information on the particular topic along.
Climate Change Causes Effects and Solutions PDF
- Greenhouse Gases
Greenhouse gases play a vital role in the earth’s climate cycles. As the planet gets hit with the sun’s rays, some of the energy is absorbed, and the rest of that energy and heat gets reflected into space. Greenhouse gases in the atmosphere trap the reflected energy, redirecting it back down to the earth and eventually contributing to global warming. Various gases play this role, including:
- Water vapor
- Carbon dioxide (CO2)
- Nitrous oxide
- Chlorofluorocarbons (CFCs)
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 both natural and human-made causes and is one of the leading contributors to climate change. CO2 has been increasing at an alarming rate and has the potential to stay in the earth’s atmosphere for thousands of years unless it gets absorbed by the ocean, land, trees, and other sources.
However, as CO2 production has steadily risen, the earth’s natural resources to absorb it has also been diminished. This is already occurring in many ways as eath’s resources are disappearing from things like deforestation. Some studies even predict that plants and soil will be able to absorb less CO2 as the eath continues to warm—possibly accelerating climate change even further.
- Solar Activity
Solar activity, as mentioned above, does play a role in the earth’s climate. While the sun does go through natural cycles, increasing and decreasing the amount of energy that it emits to the earth, it is unlikely that solar activity is a major contributor to global warming or climate change. Since scientists began to measure the sun’s energy hitting our atmosphere, there has not been a measurable upward trend.
There are many significant ways in which agriculture impacts climate change. From deforestation in places like the Amazon to the transportation and livestock that it takes to support agricultural efforts around the world, agriculture is responsible for a significant portion of the world’s greenhouse gas emissions.
However, agriculture is also an area that is making tremendous strides to become more sustainable. As productivity increases, less carbon is being emitted to produce more food. Agriculture also has the potential to act as a carbon sink, and could eventually absorb nearly the same amount of CO2 it emits.
Deforestation and climate change often go hand in hand. Not only does climate change increase deforestation by way of wildfires and other extreme weather, but deforestation is also a major contributor to global warming. According to the Earth Day Network, deforestation is the second leading contributor to global greenhouse gasses.
Many people and organizations fighting against climate change point to reducing deforestation as one of, if not the most, important issues that must be addressed to slow or prevent climate change.
- Human Activity
According to the Environmental Protection Agency, the most significant contributor to climate change in the United States is the burning of fossil fuels for electricity, heat, and transportation. Of these factors, transportation in the form of cars, trucks, ships, trains, and planes emits the largest percentage of CO2–speeding up global warming and remaining a significant cause of climate change.
While interconnected to many of the agricultural and deforestation issues we have already touched on, livestock in the form of cattle, sheep, pigs, and poultry play a significant role in climate change. According to one study, “Livestock and Climate Change,” livestock around the world is responsible for 51% of annual global greenhouse gas emissions.
Immediate Effects of Climate Change
From melting glaciers to more extreme weather patterns, people everywhere are beginning to take notice of the real impacts of climate change. While some nations around the world are taking action with initiatives such as the Paris Climate Agreement, others are continuing business as usual–pumping millions of tons of carbon into the atmosphere year after year. While the long-term consequences are still to be seen, for now, climate change continues to cause extreme weather as well as safety and economic challenges on a global scale.
- Extreme Weather
Changes to weather are perhaps the most noticeable effect of climate change for the average person. One reason for this is the financial impact severe weather events can have. So far in the U.S. during 2019, there have been six climate disasters, most costing more than $1 billion.
According to the National Climate Assessment, extreme weather events will continue to increase in frequency and intensity as climate change continues to happen. Extreme weather influenced by climate change includes:
- Stronger storms & hurricanes
- More flooding
- Heavier droughts
Safety & Economic Challenges
In 2014 the U.S. Department of Defense released a report that stated climate change posed a severe and immediate threat to national security. According to former Secretary of Defense, Chuck Hagel, “Rising global temperatures, changing precipitation patterns, climbing sea levels, and more extreme weather events will intensify the challenges of global instability, hunger, poverty, and conflict.”
Furthermore, climate change is likely to cause economic challenges in many parts of the world. Some estimates have the U.S. already spending around $240 billion annually due to human-caused climate change, and future costs are projected to be even higher.
However, putting an exact number on the real costs of climate change is difficult once you consider the staggering costs of losing natural resources like clean air and water.
Long Term Impact of Climate Change
The long term impact of climate change could be absolutely devastating to the planet and everyone and everything living on it. If the world continues on its current trajectory, then we will likely continue to see increasing effects on everyday life.
Health There are many ways in which climate change could impact people’s health. Depending on age, location, and economic status, climate change is already affecting the health of many and has the potential to impact millions more. According to the Center for Disease Control and Prevention, climate change-related health risks may include:
- Heat-related illness
- Injuries and fatalities from severe weather
- Asthma & cardiovascular disease from air pollution
- Respiratory problems from increased allergens
- Diseases from poor water quality
- Water & food supply insecurities
Negative Impact in Ecosystems
Ecosystems are interconnected webs of living organisms that help support all kinds of plant and biological life. Climate change is already changing seasonal weather patterns and disrupting food distribution for plants and animals throughout the world, potentially causing mass extinction events. Some studies estimate that nearly 30% of plant and animal species are at risk of extinction if global temperatures continue to rise.
- Water & Food Resources
Climate change could have a significant impact on food and water supplies. Severe weather and increased temperatures will continue to limit crop productivity and increase the demand for water. With food demand expected to increase by nearly 70% by 2050, the problem will likely only get worse.
- Sea Levels Rising
Rising sea levels could have far-reaching effects on coastal cities and habitats. Increasing ocean temperatures and melting ice sheets have steadily contributed to the rise of sea levels on a global scale. At current rates the National Oceanic and Atmospheric Administration estimate sea levels to rise by at least 8 inches by 2100, potentially causing increased flooding and decrease in ocean and wetland habitats.
- Shrinking Ice Sheets
While contributing to rising sea levels, shrinking ice sheets present their own set of unique problems, including increased global temperatures and greenhouse gas emissions. Climate change has driven summer melt of the ice sheets covering Greenland and Antarctica to increase by nearly 30% since 1979.
- Ocean Acidification
The ocean is one of the main ways in which CO2 gets absorbed. While at first glance that may sound like a net positive, the increasingly human-caused CO2 is pushing the world’s oceans to their limits and causing increased acidity. As pH levels in the ocean decrease, shellfish have difficulty reproducing, and much of the oceans’ food cycle becomes disrupted.
Solutions for Climate Change
While the effects of climate change can seem bleak, there is still hope. By taking immediate action to curb climate change, we may never see the worst consequences. Likewise, as the world adopts cleaner, more sustainable energy solutions, there may be millions of new jobs created and billions of dollars of economic benefits.
