What Climate Change Mitigation Is

The UN’s climate panel has published its strategies for climate change mitigation. Such document from the Intergovernmental Panel on Climate Change (IPCC) looks at options in preventing or limiting greenhouse gas emissions and promoting activities that would get rid of them in the atmosphere.

What Climate Change Mitigation Is

What is climate change mitigation?

Mitigation pertains to the efforts of cutting or preventing greenhouse gas emissions – these limit the degree of warming in the future. This includes attempts to get rid of greenhouse gases from the atmosphere. It is different from what they call climate change adaptation, which pertains to actions that should be taken in order to manage the inevitable effects of climate change. Adaptation is discussed in the IPCC’s group 2 report.

Mitigation may require changes in people’s behavior, sources of clean energy, new technologies, and the more efficient use of older technologies.

What Climate Change Mitigation Is

Which technologies are helpful?

Shifting to nuclear energy, hydroelectric, geothermal, solar, wind power and other low-carbon energy sources is among the main strategies in lowering greenhouse gas emissions in the atmosphere.

Taking renewable energy from resources that don’t get consumed through time is ever increasing. Figures from the UN reveal that renewable energy has raised its total energy generation in the previous year from 7.8% to 8.5%. They have also revealed that investments have fallen to at least 14%.

Such technologies are still facing barriers relating to capital costs (such as costs for building and maintaining the plants), public perception, financing, and a long-lasting dependence of institutions and markets on the use of fossil fuels.

The IPCC’s third report mentioned a lot of renewable energy technologies that have progressed in both cost and performance, and the roles they have in providing energy security and reducing air pollution outweigh other disadvantages.

The degree of such challenge is immense since fossil fuels constitute 80% of the energy on earth. Technologies like carbon capture and storage (CCS) can help reduce the bad effects.

What Causes the Long Term Climate Changes?

Earth’s climate has drastically changed over a period of time. It’s unthinkable that all living things can live in a certain period, which is the ice age, and now our planet swings from being ice-free. Many scientists are interested in studying sediments deposit that will have the answer and better understanding of long-term variation.

What Causes the Long Term Climate Changes?

Weather fluctuates from day to day and people across the globe experiences extreme hurricanes, tornados, floods and droughts; where climate is based on temperatures averages and long-term precipitation. The change of matter and energy in the land, atmosphere and ocean has a major role in reallocating heat all over the earth and sustaining global climate. One theory that greatly influenced and explained the long-term climate changes is the Milankovitch Cycles, where it describes the earth’s climate changes through the angle of earth’s tilt, precision of the earth and peculiarity of earth’s orbit.

In addition, scientific investigations such as Expidition 341, which involves the study of fossils, sediments, rocks, corals, ice cores, tree rings and other information contained in the rock record and evidence acquired from nature mirror astronomical observations. There are evidences found in Gulf of Alaska where glacial and interglacial, as scientist dig deeper through Pleistocene sediments.

What Causes the Long Term Climate Changes?

Milankovitch theory helps us understand climate changes over a period of 100,000 year scale but the factor found in his theory is not only the elements affecting the weather. Elements such as composition of gases in the atmosphere, especially carbon dioxide, also affect the earth’s climate because it changes the atmosphere’s temperature and sometimes it doubles or triples the level of its natural temperature.

Overtime, atmospheric greenhouse effect and plate tectonics affect weather climate. This movements cause currents to flow from the warm equatorial regions to moderate weather regions drastically resulting a sudden and unbalanced weather. In addition, the location of continents affects ocean flows and in the course of periods of active plate activities, carbon dioxide may be formed by faster rate spreading and a consequent increased in volcanism.

Types of Environmental Pollution and Its Causes

Environmental pollution is the greatest threat and danger to Earth and its dwellers. Pollution refers to impurity added to our environment or surrounding. It is categorized into different kinds, such as water pollution, air pollution, soil and sound pollution. Now, let’s get to know each one of them.

Types of Environmental Pollution and Its Causes

Air Pollution

This refers to the air getting polluted due to various reasons. Air pollution happens by means of natural and by human-induced causes. Natural air pollution takes place because of forest fire, volcanic activity, evaporation of organic compound, wind erosion, and natural radioactivity. Aside from these natural phenomena, air also gets polluted due to smoke from factories and industries, making it toxic to human’s and animal’s health.

Types of Environmental Pollution and Its Causes

Soil Pollution

Soil pollution happens when the fertility rate of soil gets diminished and becomes contaminated due to chemical mixtures and other impurities. This can be harmful to us and also to our vegetation. Soil erosion is the natural cause of soil pollution. Hospital or other industrial waste thrown and dumped over the soil is the primary cause of soil pollution.

Water Pollution

There are several things that cause water pollution. Usually, toxic substances get mixed and dissolved in water as they enter water bodies like ponds, rivers, lakes, and tanks. This deteriorates the quality of our waters and the marine ecosystem. The industrial wastes are said to be the leading cause of toxins that pollute the water. Such industrial wastes are released to the bodies of water, which then become unhygienic and contaminated.

Types of Environmental Pollution and Its Causes

Sound Pollution

This refers to any loud noise, one very uncomfortable and displeasing to the ears. This is mainly produced by road vehicles, jet planes, railway trains, and large machineries in industrial areas. Even the sound of the bass from car speakers can contribute to sound pollution, as well as the bursting of crackers in your neighborhood. Sound pollution can irritate humans and animals alike. It can also jeopardize our health.

The Two Types of Climate Changes

We, humans, often tend to feel that we are in control of everything. However, random events happen that show us that it doesn’t go that way. Extreme weather conditions, natural disasters, untimely illnesses and deaths, freak accidents, and more are extremely hard to predict and consider when planning. With these events, we are reminded about what our true nature is and the fleetingness and vulnerability of our existence. Being aware of this can alter our everyday living, goals, and priorities.

Climate is not analogous to weather. Weather is the irregular state of the atmosphere characterized by wind, temperature, clouds, precipitation, and other elements of weather. It is the result of a quickly developing and decaying weather system, such as high and low pressure systems and others. There are some common examples of weather phenomena. These are hailstorm, dust storm, fog, among others. On the other hand, climate refers to the average weather condition and its changeability in a certain period of time and area. According to the World Meteorological Organization (WMO), 30 years is the standard span of time for defining the climate of a certain region. Polar, tropical, Mediterranean, and marine are the usual examples of climate.

The Two Types of Climate Changes

Unlike before when we can anticipate when the rainy season will come and go, now we are experiencing drastic climate changes. Storms and floods are becoming more severe and frequent. And this greatly affects us, humans, especially when it comes to our health. The effects of pollution and global warming around us are becoming evident. Climate change is just one of which. Climate, though works very slowly, keeps on evolving. There are actually many causes of climate change or variation, but it is categorized into two broad frameworks.

Natural Climate Change

There are numerous natural causes that compel climate to change across scale and time. This can be further drawn down to the following categories:

The Two Types of Climate Changes
  • Natural forcings of the climate system – this has two types: the external and internal forcings. The former is associated with the changes in the orbital parameters of the Earth that manage the location and amount of solar radiation and variation in solar energy. The latter, on the other hand, comprises all the changes within the Earth’s system, including volcanic activity, ocean circulation fluctuations, and large-scale variations in the marine or cryosphere.
    • The sun and the global energy balance
    • Radiative forcing
    • Greenhouse effect
  • Natural variability of climate – from the name itself, it is caused by natural factors.
    • Global and hemisphere variability
    • Regional variability
    • Feedback
    • Internally and externally induced climate variability

Human-Induced Climate Change

Activities of humans contribute a lot to the variations in climate. The changes in the greenhouse gas concentrations (GHG), land use, and cover and aerosol levels are just some of the main causes of climate change.

  • Enhanced greenhouse effect – this is the unswerving result of human activities in the course of some processes like industrial operations, fossil fuel burning, nitrous oxide and methane in the atmosphere, and forest clearing, releasing carbon dioxide that adds danger and can destroy the ozone layer.

Now, that you’ve learned about the types of climate changes and its subtypes, you will thus become aware of the dos and don’ts for the improvement of Mother Nature.

The Essence of Adaptation to Global Warming

Global warming is the main human-induced contributor to climate change. And because of this, we are greatly suffering from our consequences. But fighting global warming and shutting down all its root causes can be too ideal to be true. We can’t just stop industries and corporations from their operations and tell people to live without the niceties of modern living. Doing this is simply unrealistic.

What experts have developed is a two-pronged approach to fight the effects of global warming – mitigation and adaptation. Mitigation is the act of dealing with the finest methods to lessen present and future carbon output, while adaptation is the simultaneous identification that global climate change is happening and the means people and the government can take to be ready for those changes. In this article, we will tackle in brief the adaptation to global warming.

In adaptation response, people search for means to reduce the effect of the issue and address it one step at a time. In mitigation, people are crooked to postponing or stopping the effects of global warming. In looking for a better term, adaptation is like “chilling” for now then gradually making some actions to reduce the effects of global warming. For instance, we know that glaciers will melt away even if we put an end to our usage of fossil fuels now, so why don’t we resort to modern developments? All they have to focus on is to learn how to “handle” the effects.

The Essence of Adaptation to Global Warming

We should begin planning for adaptation and mitigation now in order to try to reduce the impact of global warming in our lives and in our environment. But adaptation shouldn’t be made as an excuse not to mitigate global warming. These two approaches go hand in hand, and we, people, should join forces to fight our common enemy.

The Different Effects of Climate Changes

We all need a safe place to live in and our planet still needs to supply us with water, air, food and shelter. Around the globe, seasons are changing and are becoming more unstable, sea levels are rising and temperature is climbing. Climate change will transform the land and the water that we all depend on for our survival, and if we do not take care of our planet, if we continue to abuse it, our next generation will be the ones who will suffer the mistake done, leaving our children in a different world. If you don’t act now, below are the consequences of climate change that will affect in each and everyone’s life and places that you care about:

The Different Effects of Climate Changes
  • Glaciers and permafrost are melting – mountain glaciers in all areas of the world are continually decreasing in size and it means circulation of ocean is changing and it’s speeding up the warming effect in the arctic.
  • Sea level is rising – sea level rose about 6 inches or 15cm during 20th century and is still rising due to expansion of warmer seawater and melting of glaciers threatening coral reefs, wetlands and coastal communities.
  • Sea-surface temperature are warming – warmer waters contributed to the death of world’s coral reefs and many of the animals in corals died after their habitat has been weakened through bleaching, which is the process tied to warm marine life.
  • Heavier rainfall – warmer temperatures can cause heavy and intense rainfall in some areas and this heavy rainfall will cause flooding in many low land regions and will affect the economic and social life of every individual.
  • Extreme drought – as temperature increases, evaporation of higher rate happens and it will lead to dryness of the land in some areas and crops will wither, causing decline in crop productivity and the consequence will affect the economy where shortage of food supplies are prevalent.
  • Heat waves – warmer temperature will cause heat waves that result in death to all living things.
  • Wild life at risk – the rapid climate change will likely to affect the ability of many species to adjust and adapt the changes in its environment and the result will be forced migration, and the worst is death of species or extinction of species.
  • Stronger storms – storm gets their energy from warm water; as sea temperatures increases, developing storm will continually contain more energy and become more intense unleashing stronger winds and causing more damage to communities and coastal areas.
The Different Effects of Climate Changes

The rapid change in climate will become a problem to human’s economic, health and properties.

Several Reasons for Climate Changes

Our earth is always experiencing climate changes. Even in the past, our planet suffered climate unevenness when energy was imbalanced; loses and gains of heat were experienced, and the temperature continued to change. Climate change is an all natural occurrence and even if our technology did not fully evolve or develop, climate changes will still happen. Climate will react to whatever forces it to change and today, humans are the dominant force that influences climate change irregularly. The average temperature and its long-term state are measured by the steadiness between the outgoing and incoming energy as well as factors that causes changes are referred to climate forces which could lead to a warm and cool earth depending on the cause of change. Factors that cause our climate to change can be divided in three categories. Each category will determine the reason how it affects climate to change. Below are the three reasons why we have climate change:

Several Reasons for Climate Changes
  • Human causes – climate change can be directly pointed to human activities such as conversion of lands for agriculture and forestry and burning of fossil fuel. When the Industrial Revolution started, the climate system increased noticeably because of the activities where the land surface was changed and it emits substances to the atmosphere, and this activity will influence both the outgoing and incoming amount of energy and the effect on the climate can be both warm and cool. The prevailing products that contribute most in greenhouse effect are through fossil fuel combustion which emits massive carbon dioxide. The enhancement of natural greenhouse effect which the human had cause made the planet warmer and such climate change may lead to the environmental, economic and social concerns.
  • Natural causes – our planet’s weather can be affected by natural factors such as earth’s orbit around the sun, solar output and volcanic eruption or activity. Volcanic activity made short-term effects on our climate and it is episodic. Solar radiance has affected our climate system and because of the human activities, it added more greenhouse gases to our atmosphere ten times the output of sun’s radiation.
  • Long-lived and short-lived climate forcers – carbon dioxide is the primary contributory factor that affects our climate. It has been emitted for a long period of time and vast quantities from burning fossil fuels; this would mean that it will continually affect our atmosphere in its long residence time. Some substances that cause the climate system change may be of short-live forcers which can be treated and removed quickly from the atmosphere.
Several Reasons for Climate Changes

Our climate is constantly changing and such factors which is natural or man-made activities can contribute the change in climate dramatically.

Proactive Solutions to Climate Change

One of the rising and serious problems that the world is facing today is climate change. Climate change is basically a significant change on the distribution of the weather that happens over a period of time. Recently, the government and several scientists have noticed how the environment is beginning to slowly deteriorate which lead them to devise and act on proactive solutions to counter its effects. These solutions primarily vary in the different levels of society; however, it is important to note that big changes start from small ones.

Proactive Solutions to Climate Change

Individuals

Most of us do not know that we, as individuals, actually play a major part in climate change. Our daily consumption of electricity and energy can emits high levels of carbon dioxide which greatly affects the environment. According to the author of “The Climate Challenge: 101 Solutions to Global Warming”, Guy Dauncey, lessening electric consumption and usage of energy-saving options can help in decreasing the effects of climate change. As simple as turning off appliances and devices when not in use can help save at least 420 kg of carbon dioxide each year. Replacement of 20 light bulbs with CFLs or Compact Fluorescent Lamps helps reduce 1,000 kg of carbon dioxide in a year.

Community

The community as a whole can also help lessen the effects of climate change through organizing drives and programs to help increase environmental awareness. As a matter of fact, some cities nowadays offer various services and resources wherein they encourage the use of public transportation and car pools, rather than private vehicles. This helps in the environment because it decrease the total usage of crude oil they save at least 219 gallons a year. The local government can also help through implementing transportation laws.

Proactive Solutions to Climate Change

Nation

National environmental efforts can be done through increasing public awareness not only to adults but to kids as well. The government nowadays is sponsoring documentaries and environmental awareness programs with the aim on getting everyone engaged. Through this, the trend of environmental awareness may spread worldwide. Educating students about climate change is also very important; the focus of the topics should not only be about the effects of climate change but, most importantly various proactive solutions that students themselves can perform.

Proactive Solutions to Climate Change

Global

In order to help the environment, countries all over the world can counter the effects of climate change by protecting the natural resources. Deforestation must be avoided, as well as decreasing the consumption of wood materials. Aside from that, tropical rainforests should also be reserved as it actually accounts for at least 16% reduction of global carbon dioxide emissions.

Polar Bears and Climate Change

Climate change affects not only our weather but also other living things, aside from humans. One of the animals that are greatly affected by this problem is the polar bears. According to several researchers, the polar bear population decreases if climate change progresses as time pass. As we all know, annual average temperatures continue to rise each year as a result of global warming and this progresses primarily because our environmental efforts haven’t taken effect just yet.

Polar Bears and Climate Change

The Habitat of Polar Bears

Polar bears primarily live in the Arctic region of the world where they can practically walk around layers of thick ice. As the ice begin to melt due to increasing temperatures, their natural habitat is slowly getting destroyed. Thus, if climate change worsens, the only surviving polar bears will be those who are being held captive in the zoos.

Polar Bears and Climate Change

Food Sources of Polar Bears

Climate change does not only affect natural habitats of polar bears, but food sources as well. Polar bears primarily feed on seals. Since seals actually have to move to look for their own food in the ocean or sea, polar bears have to move as well. And since their natural habitat is destroyed, they might find themselves too close to the humans who may harm them and vice versa.

Polar Bears Adaptation to Warmer Climates

Polar bears may be able to adapt to warmer temperatures as time pass. However, they may have to change food sources which may, in turn, affect the homeostasis of the food chain. Thus, it may affect their capabilities in surviving the wild. While evolution can happen, a huge loss of numbers may occur first to determine who of them will survive.

Polar Bears and Climate Change

Problems in Climate Change for Polar Bears

According to researches, the main problem for polar bears in climate change is attributed to the changes in ice mass. They usually walk along the ice to go back and forth from land and water. Since there is an increase in temperature, ice formations may melt or break off. Thus, there is a possibility that they may get stranded on a piece of land where there are no sufficient food for them to fend on.

Natural Climate Changes – What Are These?

Climate change is a great and permanent change in the statistical allocation of weather patterns over periods that range from decades to millions of years. In today’s era, climate variations have become very evident. Days are getting warmer; rains and storms are getting stronger and more frequently experienced. The climate has been extremely crazy that we are greatly affected by the result. For this reason, it pays for us to be knowledgeable about this matter. In this article, we will tackle more about the natural causes of climate changes.

Natural Climate Changes – What Are These?

Climate changes are caused by some factors. Yes, it’s true for a fact that some unhealthy human activities contribute to the changes of our weather now. However, natural factors also cause such variations. Normal atmospheric changes are the cause of natural climate change. Natural climate change is caused by a number of factors or climate forcings, which include ocean variations, plate tectonics, volcanic activity, orbital fluctuations, tilting of planet, and changes in the sun’s output.

From these natural factors, volcanic activity and change in solar radiation are the two most relevant on the timescale of existing climate change. When it comes to the energy balance of the Earth, these factors mainly contribute to the level of the incoming energy. Volcanic eruptions are episodic phenomena and have fairly short-term effects on our climate. The sun is the Earth’s ultimate source of energy input. Variations in solar radiance, both long and short term, on the other hand, have contributed to climate trends in the past centuries. However, ever since the industrial revolution, the impact of additions to greenhouse gases towards the atmosphere became ten times stronger than that of the changes in solar output.

Natural Climate Changes – What Are These?

Though the natural causes of climate change is beyond human control, we can still work together to save the world. And we can make this happen by preventing human-induced climate changes. This is where we can make great and beautiful changes in our dear planet.
