The science of climate change: Climate change refers to the long-term changes in global temperatures and weather patterns, which are primarily caused by human activities such as burning fossil fuels, deforestation, and industrial agriculture. The scientific consensus is that climate change is real, and it is happening at an unprecedented rate.
Impacts of climate change: Climate change has significant and far-reaching impacts on both natural systems and human societies. Rising temperatures and changing precipitation patterns lead to more frequent and severe extreme weather events such as heatwaves, droughts, floods, and storms. Climate change also affects global food security, water availability, public health, and ecosystems.
Mitigation and adaptation strategies: Mitigation strategies aim to reduce greenhouse gas emissions and limit the magnitude of climate change, while adaptation strategies focus on adapting to the unavoidable impacts of climate change. Examples of mitigation strategies include renewable energy, energy efficiency, carbon pricing, and green infrastructure. Adaptation strategies include building sea walls, improving water management, and developing climate-resilient crops.
Policy and international cooperation: Addressing climate change requires global cooperation and coordinated action. The United Nations Framework Convention on Climate Change (UNFCCC) is an international treaty that aims to stabilize greenhouse gas concentrations in the atmosphere and prevent dangerous anthropogenic interference with the climate system. The Paris Agreement, adopted in 2015, sets a goal of limiting global warming to well below 2 degrees Celsius above pre-industrial levels.
Climate justice and equity: Climate change affects different populations and communities differently, and vulnerable groups such as low-income communities, indigenous peoples, and people in developing countries are disproportionately impacted. Climate justice and equity require addressing the social and economic inequalities that drive and exacerbate climate change and ensuring that the burden of climate action and adaptation is shared fairly.
