risk that dangerous and possibly catastrophic changes in the global environment will occur. For this reason,
the international community has recognized the need to keep warming well below 2°C and pursue efforts
to limit it to 1.5°C
3 Causes for rising emissions
• Burning coal, oil and gas produces carbon dioxide and nitrous oxide.
• Cutting down forests (deforestation). Trees help to regulate the climate by absorbing CO2 from the
atmosphere. When they are cut down, that beneficial effect is lost and the carbon stored in the trees is
released into the atmosphere, adding to the greenhouse effect
• Increasing livestock farming. Cows and sheep produce large amounts of methane when they digest their
food.
• Fertilizers containing nitrogen produce nitrous oxide emissions.
• Fluorinated gases are emitted from equipment and products that use these gases. Such emissions have a
very strong warming effect, up to 23000 times greater than CO2.
Components of climate change: Climate change has already begun to impact our planet in more ways than we
can think. Temperatures continue to rise throughout the planet and we are experiencing changes in precipitation
patterns as we have never seen before. The main cause of these catastrophic effects on our planet is pollution.
Harmful effect of climate change: The layer of Greenhouse Gases (GHG), including carbon dioxide (CO2),
methane, nitrous oxide and others, in their optimum concentration in Earth’s atmosphere, acts like a protective
blanket which maintains its temperature and the natural ecosystem. Lately, anthropogenic (human induced)
activities, mainly burning of fossil fuels, have resulted in increasing the concentration of these gases which in turn
trap extra heat and increase Earth’s average temperature leading to climate change. This in turn leads to a wide
ranging impact including sea level rise, melting of snow and glaciers, changes in weather patterns, increased
frequency and intensity of extreme events and natural disasters etc.
Factors affecting climate change: Fortunately, there are always things that we can do to fight against climate
change. Saving the environment starts with us and it is our responsibility to act against these terrible changes to
preserve the planet for future generations.
Prevention of climate change and best ways to help environment

1 Make your commute green
Millions of people drive to work every day. It is simply unavoidable in our modern-day society. However, the
downside to this is that millions of cars emit greenhouse gases that destroy our atmosphere. Vehicle emissions
are a close second when it comes to the top causes of climate change.
There are always other options that you can utilize to make your commute to work eco-friendly. For starters,
taking public transportation to work is a great way to cut out emissions. Riding your bike to work is also incredibly
helpful to the environment and is a great method to get exercise.
2 Be more conservative with energy usage

Becoming more energy efficient is a great way to prevent pollution. It causes the power plants to expend less
energy that can lead to the production of greenhouse gasses. This means that you should do what you can to cut
down on energy usage in your household.
Make sure to turn off lights and unplug devices that you are not using anymore when you are done with them.
Replace your light bulbs with energy-efficient light bulbs to help you save electricity too.
3 Get active and vote

One of the best ways to improve climate change is to help those who will fight against it get into office. This means
voting for legislation and politicians that aid against the detrimental effects of climate change. Many corporations
have politicians on their payroll and use them to lobby against legislation that would require more regulations
against them. Voting the right people into office will help pass legislation that allows us to fight against these
corporations that are mainly to blame for climate change.
