What are the Factors that Affect Climate?
Here is a list of factors affecting climate change -
A. Natural Causes
Ocean Currents: They tend to influence the temperature of a place significantly. It can either increase a region’s overall temperature or decrease it by transferring the land’s heat energy to the sea and vice versa.
Topography: The shape of land also influences the climate of a region. For instance, low-lying areas are relatively hotter and receive less rainfall than those regions situated at a higher altitude, especially in the mountainous areas.
Wind Directions: The directions of wind, both to and from where it is blowing have an impact on the climate as well. For instance, if the wind blows from a humid region it is likely to be colder while the wind blowing from a dry area is mostly hot.
Distance From the Sea: Likewise, nearness to the sea and other water bodies is an influential factor. For instance, the coastal areas are wetter and cooler than interior regions.
El Nino Phenomenon: El Nino or the uneven heating of the water surface in the Pacific tends to affect both rainfall and wind pattern. The said phenomenon is held responsible for triggering forest fires, smog, and tornadoes across many regions.
Also, the movement of continents and variation in the earth’s orbit are among the natural factors that affect climate change.
B. Man Made Cause
Pollution: Emissions from vehicles, industrial wastes, burning fossil fuels, etc. are among the major factors of climate change.
Increase in Population: With an increase in population, the demand for crop production, land, and use of fossil fuel has also increased. Resultantly, the climate has also undergone a noticeable difference.
Deforestation: Rampant felling of trees and clearing off patches of forest to accommodate agricultural practices is mostly responsible for a change in the climate.

Introduction to Climate Change
Climate change refers to persisting changes in the temperature and weather of the earth. The temperature of the earth is getting warmer every day. Clean glaciers are beginning to melt, greenhouse gases are clouding the world, sea levels are rising, and global warming is imminent. Without control, atmospheric conditions can get much worse or severe enough to be life-threatening. If these conditions continue to intensify then it will cause loss of life, several species have already gone extinct.
Human activities such as the burning of fossil fuels such as coal, oil and gas have been the major climate forcers. Burning fossil fuels emits greenhouse gases. It acts like a blanket that wraps around the earth, trapping the heat of the sun and raising its temperature.
Examples of greenhouse gasses such as carbon dioxide and methane gas are causing climate change. These occur, for example, by using gasoline to drive a car or coal to heat a building. Logging of land and forests can also release carbon dioxide. Energy, industry, transportation, buildings, agriculture and land use are the main sources of emissions.
Climate and Weather
Weather and climate are two different conditions. Most of us have seen weather forecasts on the news where weather forecasters are talking about temperature, cloud cover, humidity, and whether a storm will come in the next few days or more. This is the current state of the atmosphere at a particular location which is known as Weather.
It is the daily conditions of a place or atmosphere. It can be cloudy, sunny, rainy, stormy, or sunny. In contrast to the weather, the climate is a long-term condition in a particular region. This refers to the average weather over the years at a location. Weather can change in just a few hours, but climate takes over a hundred years to change. However, in recent years, it's changing at an alarming rate. This explains why the desert is too hot while the poles are frozen.
Factors Affecting Climate Change
The atmosphere warms the surface of the earth by passing heat from the sun. After that, the surface of the earth emits heat. This heat is absorbed by greenhouse gases (methane, carbon dioxide, nitrous oxide, etc.) and radiates heat to the earth, this phenomenon is well known as the greenhouse effect. The greenhouse effect is one of the major factors affecting the climate in the long run.
Human Factors Increase Global Warming
Burning fossil fuels such as coal, gas, and petroleum releases carbon dioxide into the atmosphere.
Logging trees absorb carbon dioxide during photosynthesis. As they diminish, the atmosphere contains more carbon dioxide.
Landfill waste produces methane when the waste decomposes.
Agricultural practices result in the release of nitrogen oxides into the atmosphere.
Natural Factors That Promote Global Warming
Orbital changes The Earth has periods of natural warming and cooling caused by Milankovitch cycles, or changes in the Earth's tilts and orbits around the Sun.
Carbon dioxide is emitted into the atmosphere when volcanic eruptions take place.
There may be fluctuations in solar power generation and the amount of solar radiation. When released in large quantities, the temperature of the earth rises.
FAQs on An Introduction to Effects of Climate Changes
1. What is the fundamental definition of climate change?
Climate change refers to the long-term, significant alteration in the average weather patterns that have come to define Earth's local, regional, and global climates. It is primarily characterised by a sustained rise in global temperatures, often called global warming, driven by both natural processes and human activities.
2. What is the main difference between weather and climate?
The primary difference lies in the timescale. Weather refers to the short-term atmospheric conditions in a specific place at a specific time, such as daily temperature, rain, or wind. Climate, on the other hand, describes the average weather conditions in a region over a very long period, typically 30 years or more.
3. What are the major causes of climate change?
The causes of climate change can be broadly categorised into two types:
- Human-Made Causes: These are the dominant drivers of recent climate change and include the burning of fossil fuels (coal, oil, gas), deforestation, industrial processes, and certain agricultural practices that release greenhouse gases.
- Natural Causes: These include variations in the Earth's orbit (Milankovitch cycles), volcanic eruptions that release gases and aerosols, and changes in solar radiation.
4. What are some of the most significant effects of climate change on the environment?
Some of the most critical environmental effects include:
- Rising Sea Levels due to the melting of glaciers and ice sheets.
- Increased frequency and intensity of extreme weather events like hurricanes, droughts, and heatwaves.
- Ocean acidification as oceans absorb excess carbon dioxide, harming marine life.
- Loss of biodiversity and species extinction as habitats change faster than species can adapt.
- Disruption of precipitation patterns, leading to water shortages in some regions and flooding in others.
5. What are greenhouse gases and how do they contribute to the greenhouse effect?
Greenhouse gases are gases in the atmosphere, such as carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O), that trap heat. They allow sunlight to pass through and warm the Earth's surface. However, when the Earth radiates heat back, these gases absorb it, preventing it from escaping into space. This process, known as the greenhouse effect, keeps the planet warm, but an excess of these gases from human activities has intensified the effect, leading to global warming.
6. How do natural factors like topography and ocean currents influence a region's climate?
Topography and ocean currents are powerful natural climate regulators. Topography, the shape of the land, affects climate as higher altitudes are generally cooler than low-lying areas. Mountain ranges can also create 'rain shadows' by blocking moisture-laden winds. Ocean currents act like massive conveyor belts, transporting warm and cold water across the globe, which in turn influences the temperature and precipitation of coastal and inland regions.
7. Why is deforestation considered a primary driver of climate change?
Deforestation impacts climate change in two major ways. Firstly, it eliminates vital carbon sinks; forests absorb vast amounts of carbon dioxide from the atmosphere during photosynthesis. When they are cut down, this absorption capacity is lost. Secondly, when trees are burned or left to decay to clear land, the carbon they have stored over their lifetime is released back into the atmosphere as CO₂, further intensifying the greenhouse effect.
8. Beyond environmental damage, how does climate change affect human health and society?
Climate change poses direct threats to human well-being. These impacts include heat-induced health issues like heatstroke, the spread of vector-borne diseases such as malaria and dengue as warmer temperatures expand mosquito habitats, food and water shortages due to rampant crop losses and droughts, and displacement of communities from coastal flooding and shoreline erosion.
9. What are 'climate forcers' and what is an example?
Climate forcers are substances or factors that influence the Earth's energy balance, causing the climate to either warm or cool. The most well-known climate forcer is carbon dioxide (CO₂), which has a warming effect. Other examples include methane and black carbon (soot), which also warm the climate, while certain aerosols can have a temporary cooling effect by reflecting sunlight.
10. What are some key mitigation strategies to address climate change?
Mitigation involves actions to reduce or prevent greenhouse gas emissions. Key strategies include:
- Transitioning from fossil fuels to alternative energy sources like solar, wind, and geothermal power.
- Improving energy efficiency in buildings, transportation, and industries.
- Promoting afforestation and reforestation to enhance natural carbon sinks.
- Adopting sustainable agricultural and land-use practices.
- Developing and deploying carbon capture technologies to trap emissions at their source.
