Climate change is one of the most pressing environmental issues of our time. As the planet continues to warm due to the burning of fossil fuels, extreme weather becomes more and more frequent.
The biggest contributor to climate change in 2021 is human-generated greenhouse gas pollution. This is primarily caused by burning fossil fuels such as coal, oil, and natural gas. These activities release carbon dioxide and other gases into the atmosphere, trapping heat and resulting in global warming. In addition, deforestation and land-use change also greatly increase the amount of carbon dioxide in the atmosphere, contributing to rising temperatures.
Governments around the world are beginning to take action to reduce emissions of greenhouse gases and other pollutants, but the pace and extent is not yet at a level consistent with keeping global warming below catastrophic levels. To do this, it would require transitioning to a low-carbon energy system and placing greater value on conserving resources.
One way to make a difference is through energy conservation. This could be as simple as making sure your house is well insulated, turning off lights and appliances not in use, and reducing your reliance on cars for transportation. Many countries are now offering tax breaks to households and businesses that invest in renewable energy sources such as solar and wind.
Greenhouse gas emissions must be dramatically reduced in order to halt and reverse climate change. 2021 is a pivotal year—governments, citizens, and businesses have the opportunity to make a meaningful impact by transitioning to clean energy sources and increasing energy efficiency.
