<<–2/”>a >p style=”text-align: center;”>The Greenhouse Effect
The greenhouse effect is a natural phenomenon that insulates the Earth . Incoming solar radiations are absorbed and reemitted back from the Earth’s surface as infrared energy, greenhouse gases (GHGs) in the Atmosphere prevent some of this heat from escaping into space, instead reflecting the energy back to further warm the surface. Human activities that produce GHGs (anthropogenic) amplify the greenhouse effect. Anthropogenic GHG emissions are modifying the Earth’s energy balance between incoming solar radiation and the heat released back into space, resulting in Climate change. Gases such as CO2 , NO2 , CFCs (chloro fluorocarbons) allow sun rays to pass through them but then absorb and reradiate the heat back towards the earth. These are therefore termed as Green House Gases.
The amount of Solar Energy absorbed or radiated by Earth is modulated by the atmosphere and depends on its composition. Greenhouse gases—such as water vapor, carbon dioxide, and methane—occur naturally in small amounts and absorb and release heat energy more efficiently than abundant atmospheric gases like nitrogen and Oxygen. Small increases in carbon dioxide concentration have a large effect on the climate system.
Mazor Green House gases are:-
Carbon Dioxide (CO2)- 0.038%
Water Vapor (H20) -0-4%
Methane (CH4) -trace amount
Sulfur dioxide (SO2) -trace amount
Ozone (O3) -trace amount
Nitrogen oxides(NO, NO2, N2O)- trace amount

The greenhouse effect is a natural process that warms the Earth’s surface. When sunlight hits the Earth’s atmosphere, some of the energy is reflected back to space, and some of it is absorbed and re-radiated by greenhouse gases. These gases trap heat in the atmosphere, which warms the planet.
The main greenhouse gases are water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Human activities are increasing the levels of these gases in the atmosphere, which is causing the greenhouse effect to become stronger. This is leading to Climate Change, which is a long-term change in the Earth’s climate.
Climate change is already having a significant impact on the planet. It is causing sea levels to rise, Glaciers to melt, and extreme weather events to become more common. These changes are having a devastating impact on people and Ecosystems around the world.
There are a number of things that can be done to mitigate greenhouse gas emissions and reduce the Impact Of Climate Change. These include:
- Reducing our reliance on fossil fuels and switching to renewable energy sources
- Improving energy efficiency
- Reducing deforestation
- Protecting and restoring forests
- Investing in sustainable agriculture
- Reducing food waste
- Changing our transportation habits
- Making our homes and businesses more energy-efficient
Climate change is a serious problem, but it is not too late to take action. By working together, we can reduce greenhouse gas emissions and protect our planet for future generations.
Ocean Acidification is a serious problem that is caused by the increasing levels of carbon dioxide in the atmosphere. When carbon dioxide dissolves in the ocean, it forms carbonic acid. This acid can harm marine life, coral reefs, and other ecosystems.
Deforestation is the clearing of forests for other uses, such as agriculture, development, or logging. Deforestation can lead to a number of problems, including climate change, soil erosion, and Biodiversity-2/”>Biodiversity loss.

What is Global Warming?
Global warming is the long-term heating of Earth’s climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere. The term is frequently used interchangeably with the term climate change, though the latter refers to both human- and naturally produced warming and the effects it has on our planet. It is most commonly measured as the Average increase in Earth’s global surface temperature.
What are the causes of global warming?
The primary cause of global warming is human activity, primarily the burning of fossil fuels like coal, oil and natural gas. When these fuels are burned, they release greenhouse gases into the atmosphere. Greenhouse gases trap heat in the atmosphere, which causes the planet to warm.
Other human activities that contribute to global warming include deforestation, agriculture, and industrial processes. Deforestation removes trees, which absorb carbon dioxide from the atmosphere. Agriculture releases methane, a greenhouse gas, into the atmosphere. Industrial processes also release greenhouse gases into the atmosphere.
What are the effects of global warming?
Global warming is already having a significant impact on our planet. The average global temperature has increased by about 1 degree Celsius since the pre-industrial period. This may not seem like much, but it is already having a noticeable impact on our planet.
The effects of global warming include rising sea levels, melting glaciers, more extreme weather events, and changes in plant and animal life. Rising sea levels are caused by the melting of glaciers and ice sheets. This is causing coastal flooding and erosion. Melting glaciers are also causing changes in the flow of rivers and streams.
More extreme weather events, such as hurricanes, floods, and droughts, are becoming more common due to global warming. These events can cause widespread damage and loss of life. Changes in plant and animal life are also being observed due to global warming. Some species are moving to new areas in order to find suitable habitats. Others are facing extinction due to changes in their environment.
What can we do to mitigate global warming?
There are a number of things that we can do to mitigate global warming. These include reducing our reliance on fossil fuels, investing in renewable energy sources, and improving energy efficiency. We can also make changes to our lifestyles, such as driving less, eating less meat, and recycling more.
Reducing our reliance on fossil fuels is one of the most important things that we can do to mitigate global warming. Fossil fuels are the primary source of greenhouse gas emissions. We can reduce our reliance on fossil fuels by using renewable energy sources, such as solar and wind power. We can also improve energy efficiency by making our homes and businesses more energy-efficient.
Investing in renewable energy sources is another important way to mitigate global warming. Renewable energy sources, such as solar and wind power, do not produce greenhouse gases. We can invest in renewable energy sources by installing solar panels on our homes or by buying renewable energy from our utility company.
Improving energy efficiency is another way to mitigate global warming. Energy efficiency means using less energy to do the same things. We can improve energy efficiency by making our homes and businesses more energy-efficient. We can do this by weatherizing our homes, using energy-efficient appliances, and driving more fuel-efficient cars.
Making changes to our lifestyles is another way to mitigate global warming. We can reduce our impact on the environment by driving less, eating less meat, and recycling more. We can also choose to buy products that are made from recycled materials.
By taking these steps, we can help to mitigate global warming and protect our planet for future generations.
