Climate change is a critical issue characterized by global warming and its widespread environmental and social consequences. Human activities, such as burning fossil fuels and deforestation, have accelerated the rise in greenhouse gases, leading to severe impacts like extreme weather, biodiversity loss, and health risks. Mitigation efforts, including a shift to renewable energy, are vital for adapting to and preventing the most severe outcomes.

Climate change is the long-term rise in the average temperature of the Earth's climate system, known as global warming
Human Activities
The burning of fossil fuels, deforestation, and certain agricultural practices are human activities that contribute to climate change
Natural Processes
Climate change is also driven by natural processes, but human activities have played a dominant role in recent decades
The current rate of change is occurring at a pace that challenges the ability of both human societies and natural ecosystems to adapt
Alteration of Water Cycles
Climate change can lead to more severe droughts and floods, altering water cycles
Acidification of Oceans
The increase in greenhouse gases can lead to the acidification of oceans
Loss of Biodiversity
Climate change can result in the loss of biodiversity as species struggle to adapt to changing habitats
Threats to Food Security
Climate change can impact agriculture, leading to threats to food security
Health Risks
Heatwaves and the spread of vector-borne diseases are health risks associated with climate change
Economic Damages
Extreme weather events can result in economic damages
The melting of ice caps and the expansion of seawater as it warms can lead to rising sea levels, threatening coastal communities
Increased Exposure to Heat Stress
Climate change can lead to increased exposure to heat stress
Changes in Distribution of Infectious Diseases
Climate change can impact the distribution of infectious diseases
Mental Health Challenges
Climate-related stress can lead to mental health challenges
Food and Water Shortages
Climate change can exacerbate food and water shortages
Population Displacement
Climate change can lead to population displacement
Resource Conflicts
Climate change can contribute to conflicts over resources
Vulnerable populations, particularly in developing countries, face the greatest challenges due to climate change
Scientific observations have documented a trend of escalating global temperatures
Climate models project that without significant reductions in greenhouse gas emissions, average global temperatures will continue to rise
The Paris Agreement aims to limit global warming to well below 2°C above pre-industrial levels, with efforts to restrict the increase to 1.5°C
Immediate and sustained global action is necessary to achieve the goals of the Paris Agreement and prevent the most severe impacts of climate change

Definition of global warming
Long-term rise in Earth's average temperature due to climate system changes.
01
Role of greenhouse gases in climate change
Greenhouse gases trap infrared radiation, enhancing Earth's natural greenhouse effect, causing warming.
02
Impact of climate change on adaptation
Rapid climate change outpaces the ability of human societies and ecosystems to adapt.
