In the last several decades, a number of theories on global warming and climate change have been put forward. Most of these theories suggest that global warming is the result of human activities leading to global warming. On the other hand, climate change is the result of natural climate fluctuations. It is believed that climate change is the result of human activities because greenhouse gases have been emitted which lead to global warming.
Global warming as the result of human activities is most commonly associated with the burning of fossil fuels for energy production. The burning of fossil fuels such as oil, coal and gas contributes to global warming since these fossil fuels emit carbon dioxide and other greenhouse gases.
Since the earth has a history of being subjected to such extreme climate changes, there is a high chance that future climate change will occur. The average global temperature is the result of the combined effect of land precipitation, wind, and solar radiation.
This average condition can only be described as a “condition of the atmosphere.” A sudden drastic change in the atmospheric conditions can cause drastic changes in the climate.
- One of the theories on global warming and climate change that is currently gaining importance is the theory called “topsides”. This theory suggests that the earth’s surface warm up as a result of the warming up of the ocean surface. Ocean heat is absorbed by the earth’s surface, therefore, causing an increase in atmospheric pressure. This rise in atmospheric pressure causes an increase in the earth’s temperature.
- Another theory on global warming and climate change suggests that the earths average surface temperature rise as a result of carbon dioxide released into the atmosphere. Carbon dioxide is a leading cause of global warming. Recent studies have shown that carbon dioxide is responsible for about 60% of the climate change.
Greenhouse gases are caused by a number of factors including human activities. Emissions such as those from cars and factories are major contributors to the increase in the greenhouse gas. Manmade emissions are also a cause of the decreasing amounts of carbon dioxide in the atmosphere.
There is more than one theory on global warming and climate change
Scientists have spent decades studying the atmosphere and its effects on the earth. Through research, scientists have found what causes certain types of weather to occur. They have developed theories that explain the phenomenon. Through this study, scientists have also discovered a relationship between the atmosphere and climate.
The connection between global warming and climate change is not fully understood. It is believed that future climate changes may result from greenhouse gas emissions. The concentration of greenhouse gases in the atmosphere is increasing at an alarming rate. It is believed that carbon dioxide is the cause of about one fourth of the global warming. The other causes are variations in earth orbit and solar radiation.
Causes of Global Warming
Global warming is one of the most serious environmental issues of our time. It is literally changing the world we live in. One day it will be too late because the damage is already done. Global warming is a result of the gradual increase in the Earth’s temperature over the last century, caused by the emission of carbon dioxide and other greenhouse gases from industrialised countries.
Climate change also includes the resulting large-scale changes in weather patterns and global warming caused by human-forced climate change. Global warming has recently reached its highest recorded value, with the average annual atmospheric temperature reaching +1.5C. This value has been confirmed by various scientific research agencies around the world.
While this is an increase from the normal, it is still well short of the global warming amounts caused by carbon dioxide released from burning fossil fuels. The Intergovernmental Panel on Climate change (IPCC) believes that the recent burst of El Nino has been a contributing factor to the rise in Earth’s temperatures.
Other researchers believe that the increase in Earth’s temperature is being driven more by human activities such as farming, construction and other land-related activities. While greenhouse gas levels continue to increase at a rapid rate and are likely to continue to do so for some time, the feedback cycle between climate change is not completely clear.
Some researchers believe that the Earth’s climate system is largely capable of regulating its internal temperatures, but are unable to cope with the increased output from greenhouse gases
While global warming appears to have been the cause of certain extreme weather events in the past, recent research indicates that climate change could also be responsible for the onset of the long-term global warming trend. One theory suggests that the extreme weather events which have become so common over the last half a century are caused by a change in the Earth’s atmospheric circulation.
Another theory suggests that long-term global warming is caused by the release of methane gas from wetlands and thawing permafrost regions into the atmosphere, accelerating climate change
The increased concentration of this methane, considered to be the most important source of man-made climate change, could result in a further release of methane stored in wetlands, as thawing permafrost melts, releasing this greenhouse gas. Additional research is needed to examine the link between human activities and climate change.
Although the observed increase in Earth’s temperatures is believed to be caused primarily by human activities, it is thought that some kind of natural mechanism is responsible for the recent slowdown in global warming. Since the 1950s, the United States has made every effort to monitor and document global warming.
In this process, satellite temperatures have been taken and analyzed, and a record of global warming temperatures has been recorded. Unfortunately, these records only go back so far, and even then the data is questionable. While carbon dioxide is believed to be the primary cause of global warming, other researchers think that the main driver of climate change may be the release of methane and carbon dioxide from wetlands and thawing permafrost areas.
A recent study claims that wetlands that are located near industrial facilities and power plants contain much higher levels of methane gas than those found in more remote areas. This study was published in the peer-reviewed Journal of Geophysical Research: Atmospheres.
Effects of Global Warming on the Human Health
Effects of global warming are being felt now more than ever. We have become so used to living in the twenty-first century that we have been conditioned not to see the effects of global warming. Unfortunately, the 21st century is the era of extreme weather and the effects of global warming seem to be more pronounced now than ever before.
The effects of global warming are also apparent on water resources. The average global temperature has risen by approximately 2.5 degrees since the mid-nineteen sixties. This increase in temperatures has had a devastating effect on agriculture and animal products all over the world.
In addition to the obvious effects on peoples livelihoods, global warming has been projected to have a detrimental and adverse effect on human health causing increased risks for disease and death caused by warmer temperatures. While some are blaming global warming for increasing hurricane activity there are also many scientists who believe that there is a correlation between heat waves and hurricanes.
- Heatwaves are known to bring heavy rainfall and beach storms
- Hurricanes have even been linked to super cyclones
There are many theories on what is causing these trends but most agree that it is caused by increasing greenhouse gas emissions from growing countries like the United States and China. This increase in greenhouse gases is the primary cause for what is causing the warming of the Earth.
Effects of global warming can be seen in precipitation patterns
When the Earth’s temperatures rise above freezing they produce what is called an ice age. During the winter months when the temperatures are cold temperatures in the northern hemisphere become milder and the droughts can no longer hold back the rivers and streams that provide the food supply for the population.
As the droughts worsen so do the natural flows of the rivers and the floods become more severe. In fact, the floods might become too severe that they overtake the major cities. Perhaps one of the worst effects of global warming that we can see in the real world is the effects of global temperatures on weather patterns.
While there are some theories on this there is still much that is not understood about it. There is some evidence that the warming speeds up the Earth’s core temperature which affects the atmosphere and precipitation. Many scientists believe that global temperatures will continue to rise due to human activity like the burning of fossil fuels and the resulting pollution.
The effects of global warming can be seen in the way people adapt to new climates
While there is some evidence of less tropical rain, the melting glaciers and increased humidity are showing that there will be changing climates. In many areas, people are already experiencing a shift in culture and lifestyle as a result of the global warming.
It has already started changing the way we live our lives and the consequences could be catastrophic if it continues at a fast rate. Some experts believe that we may already be witnessing signs of changes in human health and the number of diseases might increase as the effects of global warming become worse.
Global Warming Solutions – An American Approach
When it comes to global warming solutions, everyone is looking for some magic quick fix that never works. Unfortunately, there is no magic button that is going to solve this problem for good. In fact, this problem will get worse over time if we do not take action to change our habits and use more sustainable methods of energy production. Let’s look at some of the options available.
The most widely-known are the environmental solutions that deal primarily with the short-term effects, for example, rising sea levels and heavy rainstorms. However, these solutions do not address the main cause of global warming: excessive greenhouse gases being released into the atmosphere. Recent research shows that even if greenhouse gases are not reduced, gradual climate change will create a permanently “heat-shy Earth” within 20 years or so. So we have a lot of time to work on this problem!
One of the most important of the global warming solutions being discussed now are what are called “mitigation projects“. These projects aim to reduce greenhouse gas emissions from the sources that can potentially cause climate change, such as
- Carbon dioxide released from burning fossil fuels and industry processes
- Agricultural land clearing and forest clear-felling
- The manufacture of cement, iron and steel products
Each of these activities has the potential to significantly alter the global temperature, and each has the potential to cause varying degrees of climate change. The key is to do everything we can today to mitigate their impact. Unfortunately, right now, these activities are underway in many parts of the world, especially in the developing world.
There is another major force for climate change and its mitigation which is not often discussed as much, and that is the political will of the global warming solutions discussed here
The political will to solve problems like reducing carbon emissions requires strong countries behind them to pull together and act quickly to find viable solutions. The people who live in the United States, in particular, must come to collectively realize the seriousness of the situation and that they have an incredible opportunity to contribute towards finding solutions that will preserve the planet for future generations.
We need the support of all countries to make these global warming solutions a reality. It won’t be easy, but it is possible if we work hard at it together. As a matter of fact, there have been increasing calls from some very concerned scientists for the United States to lead the way in finding better ways to mitigate greenhouse gas emissions.
A recent study by eleven top climate scientists suggested that the gaps between Earth’s atmosphere and the heat it experiences are becoming larger with time. It is not clear yet how these gaps are going to be closed, but scientists are concerned that the consequences could be catastrophic.
The calls for greater action are growing by the minute, and more scientists are urging the United States to take a leading role on global warming. Scientists are also concerned about the impact that global warming will have on the world’s poor and on the ecosystems of the world’s tropical forests.
One of the most dire effects is the rapid die-off of many types of trees that are found in the tropical forests. This can be directly tied to the expansion of the carbon emissions causing the greenhouse effect, and it is likely that the death of the Amazon’s evergreen tree will have a disastrous impact on the food supply as well as the economy of the world’s poor.
Hopefully scientists and others will continue to find innovative solutions to the problems of global warming, and they will also find ways to mitigate the negative effects of the carbon emissions causing the climate change, rather than simply ignoring it.
