Climate change is one of the most pressing issues facing the world today. It refers to the long-term changes in the Earth’s climate system, mainly caused by human activities that increase the concentration of greenhouse gases in the atmosphere. Greenhouse gases, such as carbon dioxide and methane, trap the sun’s heat and warm the planet. This leads to a variety of impacts, such as rising temperatures, melting ice, sea level rise, extreme weather events, droughts, floods, wildfires, biodiversity loss, and health risks.
According to the United Nations, the average global temperature has risen by about 1.1°C since the late 1800s, and the last decade was the warmest on record. Scientists have shown that humans are responsible for virtually all of the warming over the last 200 years and that limiting the temperature increase to no more than 1.5°C would help avoid the worst consequences of climate change. However, to achieve this goal, global emissions of greenhouse gases need to be reduced by at least 45% by 2030 and reach net zero by 20501.
Climate change is a complex and multifaceted problem that requires urgent and coordinated action from all sectors of society. Some of the solutions include switching to renewable energy sources, improving energy efficiency, promoting sustainable transport and agriculture, protecting forests and ecosystems, adapting to the changing conditions, and enhancing international cooperation and solidarity. Everyone can play a role in tackling climate change by making informed choices, raising awareness, and demanding action from governments and businesses. Together, we can create a more resilient and sustainable future for ourselves and the generations to come.
