CLIMATE CHANGE
A long-term shift in the typical weather patterns that have come to characterize local, regional, and global climates on Earth is referred to as climate change. The phrase is synonymous with a wide variety of observed outcomes resulting from these changes.
Since the middle of the 20th century, human activity has been responsible for changes in Earth's climate. Burning fossil fuels, in particular, has increased the amount of heat-trapping greenhouse gases in the atmosphere, which has raised the planet's average surface temperature. Natural processes, overshadowed by human activity, can also cause climate change. These include external forcings like volcanic activity, variations in Earth's orbit, and changes in the Sun's energy output, as well as internal variability like cyclical ocean patterns like El Niño, La Niña, and the Pacific Decadal Oscillation.
GLOBAL WARMING
. The long-term warming of the Earth's surface that has been seen since the pre-industrial era (between 1850 and 1900) is known as global warming. It is caused by human activity, mainly the burning of fossil fuels, which raises the atmospheric concentrations of heat-trapping greenhouse gases. There is a difference between this word and "climate change."
The global average temperature of Earth has risen by around 1 degree Celsius (1.8 degrees Fahrenheit) from the pre-industrial era due to human activity; this value is currently rising by more than 0.2 degrees Celsius (0.36 degrees Fahrenheit) every decade. Since the 1950s, human activity has unquestionably contributed to the current warming trend, which is happening at a rate never seen in millennia.
CLIMATE
Climate change refers to the phenomenon of global warming, which is the continuous rise in the average temperature of the planet, and its impact on Earth's climate system. It also encompasses long-term changes that have occurred in the past. The current increase in global average temperature is happening at a faster rate compared to previous changes, and it is primarily caused by human activities such as the burning of fossil fuels. The use of fossil fuels, deforestation, and certain agricultural and industrial practices contribute to the emission of greenhouse gases, particularly carbon dioxide and methane. These gases trap heat in the Earth's lower atmosphere, leading to global warming.
The consequences of climate change are increasingly evident in the environment. Deserts are expanding, heat waves and wildfires are becoming more frequent, and the Arctic region is experiencing amplified warming, resulting in the thawing of permafrost, the retreat of glaciers, and the decline of sea ice. Higher temperatures also contribute to more intense storms, droughts, and other extreme weather events. Rapid environmental changes in mountains, coral reefs, and the Arctic are forcing many species to either relocate or face extinction. Even if efforts to mitigate future warming are successful, certain effects will persist for centuries, including ocean heating, ocean acidification, and sea level rise.
Climate change poses significant threats to human populations, including increased flooding, extreme heat, food and water scarcity, the spread of diseases, and economic losses. It can also lead to human migration and conflicts. The World Health Organization (WHO) has identified climate change as the greatest threat to global health in the 21st century. Without action to limit warming, societies and ecosystems will face even more severe risks. Although efforts to adapt to climate change, such as implementing flood control measures or developing drought-resistant crops, can partially reduce these risks, there are already limitations to adaptation that have been reached.

NATURAL CAUSE OF CLIMATE CHANGE
1. Climate change can be partially attributed to natural phenomena such as volcanic eruptions, solar radiation fluctuations, tectonic shifts, and changes in Earth's orbit. However, the rapid global warming observed since the industrial revolution cannot be solely explained by these natural causes. According to NASA, while these factors still play a role, they are too minor or slow to account for the current pace of warming. This challenges the misinformation spread by some in the fossil fuel industry and conservative think tanks who try to downplay human influence on climate change.
OUR LIFE STYLS CHOICES
Our daily choices as individuals, such as the products we buy, the amount of electricity we use, our modes of transportation, and our dietary habits, contribute to our personal carbon footprints. When combined, these individual footprints form humanity's overall carbon footprint. To reduce this footprint, we must first recognize the unequal distribution of climate change impacts and take action to reduce greenhouse gas emissions, particularly by those who are most responsible, without causing further harm to those who bear less responsibility.
Version 1: The significant decisions made by utilities, industries, and governments that impact the climate are ultimately influenced by our own needs, desires, and priorities. Overcoming climate change will necessitate a reevaluation of these needs, an increase in demands, and a realignment of priorities. Instead of prioritizing short-term gains for corporations, we must focus on long-term planning that benefits communities and ensures the well-being of all individuals. Climate advocacy should extend beyond mere slogans and transition into collective action, driven by a sense of urgency and supported by faith in science and our capacity to enact positive change.
