You’ve probably heard a lot about climate change in the news or seen people protesting about it. Scientists, public figures, and governments are all talking about it because it’s a big deal for our planet. But what exactly is climate change, and why is it so important?
Throughout Earth’s history, the climate has changed many times. There have been ice ages and warmer periods. The last major ice age ended about 12,000 years ago. So, if the climate has always changed, why are people so worried about it now?
Since the industrial revolution began in 1760, Earth’s average temperature has been rising faster than ever before. This rapid increase in temperature is called global warming. It’s mainly caused by the rise in greenhouse gases due to human activities. These activities include burning fossil fuels like coal and oil, cutting down forests, farming, and the breakdown of waste in landfills.
Greenhouse gases, such as carbon dioxide and methane, naturally exist in our atmosphere. They act like a blanket, trapping heat from the sun and keeping Earth warm enough for life. This is known as the greenhouse effect. However, too many greenhouse gases make this blanket too thick, causing Earth’s temperature to rise too much.
The increase in Earth’s temperature is causing ice in places like the Arctic and Antarctica to melt. This melting ice adds more water to the oceans, causing sea levels to rise. Rising sea levels threaten to submerge small islands, especially in the Pacific and Caribbean regions. They also lead to severe floods that can destroy crops and farms.
Warmer temperatures also cause oceans to heat up and evaporate faster, leading to more intense storms and heavy rainfall. Global warming is making weather more extreme, with longer droughts and heatwaves. During droughts, the dry soil and high temperatures increase the risk of wildfires.
These changes affect Earth’s ecosystems. Many animals have to move to new areas to survive, while others lose their habitats and face extinction.
Climate change is a challenge humanity has never faced before, but we can still make a difference. Communities around the world need to make smart choices and take environmentally friendly actions.
Some big solutions include switching from fossil fuels to renewable energy sources like solar, wind, and hydroelectric power. We can also reduce emissions from industries and transportation by using greener technologies. Limiting deforestation and investing in efficient farming methods, like vertical farming, can also help.
There are smaller actions you can take at home, too. You can recycle, compost organic waste, eat more vegetables, save electricity, and buy durable or reusable items.
People worldwide are working together to find solutions for climate change. For example, Bhutan is the world’s most carbon-negative country, Costa Rica uses 99 percent renewable energy, and China leads in wind power.
Climate change is a global issue, and our future depends on the actions we take today. Think about how your community is working towards a more sustainable future and what you can do to help.
Design an infographic that explains the causes and effects of climate change. Use images, charts, and brief text to make it visually appealing and informative. Share your infographic with the class to help spread awareness.
Perform a simple experiment to understand the greenhouse effect. Use two jars, thermometers, and a lamp to simulate how greenhouse gases trap heat. Record the temperature changes and discuss how this relates to global warming.
Participate in a class debate about the pros and cons of different renewable energy sources. Research solar, wind, and hydroelectric power, and present arguments for why one might be the best solution for reducing climate change.
Work in groups to develop a project that your community can implement to combat climate change. This could be a recycling program, a tree-planting event, or a campaign to reduce energy consumption. Present your plan to the class.
Compose a letter to a local government official or community leader, expressing your concerns about climate change. Suggest actions they can take to help reduce its impact and explain why these actions are important for your community’s future.

[Music] Protests around the world, headlines about extreme weather events, scientists and public figures calling for action, and governments uniting in the search for solutions. Climate change is a global issue, and we must work together to save our world.
But what exactly is climate change? Our planet’s climate has changed throughout history, alternating between ice ages and warmer periods. Earth has experienced at least five major ice ages, with the last one ending nearly 12,000 years ago. So if the climate has always changed, why is climate change such a big issue today?
Since the start of the industrial revolution in 1760, Earth’s average temperature has risen faster than ever before. This effect is known as global warming, and it’s caused by the increase of greenhouse gas emissions from human activity. Greenhouse gases occur naturally on our planet, but human activities such as the burning of fossil fuels, agriculture, deforestation, and the decomposition of waste in landfills have dramatically increased the amount of these gases.
Greenhouse gases act like a blanket around Earth, trapping heat from the sun’s rays. This is called the greenhouse effect. Thanks to this effect, Earth has just the right temperature for life to thrive, unlike other planets in our solar system. However, if the greenhouse effect becomes too strong, it starts to cause issues.
The increased temperatures we are experiencing now are causing ice in the Arctic and Antarctica, as well as glaciers and snow around the world, to melt. The water created by the melting ice pours into the oceans, causing sea levels to rise. This puts small islands in danger of disappearing, especially those in the Pacific and Caribbean regions. Rising sea levels are also causing devastating floods in many countries, which can destroy crops and farms used to feed the population.
Another effect of rising temperatures is that oceans warm up and evaporate faster than normal, increasing the occurrence of severe storms and heavy rainfall. Global warming is making weather more extreme, bringing longer droughts and heatwaves. The loss of soil moisture and high temperatures during a drought increase the risk of wildfires.
The high temperatures, both on land and in our oceans, affect Earth’s delicate ecosystems. Many animals are forced to migrate to other areas to survive, while others are losing their habitat and dying.
So, can we do anything to stop the effects of climate change? Climate change has already reached a point that humanity has never experienced before. However, the future of our planet is in our hands. Communities must make smart choices and tackle this issue with environmentally friendly actions.
Some solutions to limit global warming include switching from burning fossil fuels to renewable and greener energy sources like solar, hydroelectric, or wind energy; reducing emissions caused by industry and transportation by investing in greener technology; and limiting deforestation while investing in more space-efficient forms of agriculture like vertical farming.
These are all significant solutions, but there are also smaller actions you can easily take at home, such as recycling, composting organic waste, eating more vegetables and fewer meat products, saving electricity, and buying items that last longer or can be reused.
People around the world are working together to innovate, engineer, and develop solutions for the issue of climate change. Bhutan is the world’s most carbon-negative country, Costa Rica has achieved 99 percent renewable energy, and China is now the world leader in wind power.
