Climate change refers to long-term changes in the Earth’s climate, particularly changes in temperature, precipitation, and sea level. Climate change is primarily driven by the release of greenhouse gases, such as carbon dioxide and methane, into the atmosphere from human activities such as burning fossil fuels and deforestation.
The scientific consensus is that the Earth’s climate is changing due to human activities, and that global temperatures are rising at an unprecedented rate. This is causing a range of impacts, including more frequent and severe heatwaves, droughts, floods, storms, and wildfires. It is also leading to melting glaciers and ice caps, rising sea levels, and ocean acidification.
Climate change poses significant risks to human societies and natural systems worldwide. It threatens public health, food and water security, infrastructure, and economic stability, particularly in vulnerable regions such as low-lying coastal areas and arid regions.
Climate change is also contributing to biodiversity loss and ecosystem degradation, which in turn further exacerbates the impacts on human societies.
Efforts to address climate change are focused on reducing greenhouse gas emissions and adapting to the impacts that are already happening.
The Paris Agreement, signed in 2015, is a global agreement to limit global warming to well below 2°C above pre-industrial levels, and to pursue efforts to limit warming to 1.5°C. To meet this goal, many countries have pledged to reduce their greenhouse gas emissions and transition to renewable energy sources.
However, despite these efforts, global greenhouse gas emissions continue to rise, and the impacts of climate change are becoming more severe.
Urgent action is needed to reduce emissions and adapt to the impacts of climate change, particularly for vulnerable communities and ecosystems.
