Climate change refers to the long-term alteration of temperature and typical weather patterns on earth, primarily driven by human activities like burning fossil fuels, which release greenhouse gases into the atmosphere. This has led to an increase in global temperatures, resulting in more frequent extreme weather events, rising sea levels, and significant ecological impacts such as habitat loss and shifts in species distribution.

Vulnerable populations face heightened risks, including food insecurity and health issues, as climate change exacerbates droughts, floods, and other environmental stresses.

They are quite a lot of human activities that are causing climate change however the most popular are the following: banning fossil fuels such as coal, oil, and natural gas combustion for energy releases significant amounts of carbon dioxide (CO2) And nitrous oxide, intensifying the greenhouse effect. The clearing of forests for agriculture or Urban Development reduces carbon dioxide absorption, exacerbating atmospheric greenhouse gas concentrations.

Livestock farming produces methane, a potent greenhouse gas, while fertilizers release nitrous oxide, further contributing to climate change.

Climate change, particularly human induced climate change, began in the early 19th century. Researchers indicate that greenhouse gases started warming the oceans around the 1830s, significantly earlier than previously thought. The industrial revolution, which began around 1750, marked the start of significant human impact on the climate through increased carbon dioxide emissions from fossil fuel combustions. By the late 19th century, scientists recognized that human activities were influencing climate patterns, laying the groundwork for our current understanding of climate change.

Climate change is currently a serious global threat, impacting health, ecosystems, and economies. It contributes to extreme weather events like heat waves, floods, and droughts, which are becoming more frequent and severe. As estimated 3.6 billion people live in areas highly vulnerable to these changes, leading to projected annual deaths of about 250,000 from climate-related health issues by 2050. Additionally, climate change exacerbates existing inequalities, disproportionately affecting low-income communities and developing nations. Therefore, immediate action is crucial to mitigate these escalating impacts.

Because of climate change, there are a few regions that are most vulnerable and that include Chad ranking the highest in vulnerability, facing severe drought and resource depletion. Somalia is also struggling with drought and food insecurity, exacerbated by political instability. South Sudan with experiencing extreme flooding and conflict, hindering climate resilience and Syria affected by war and drought, with over 80% of their population below the poverty line.

Climate change is a real and undeniable threat to our entire civilization. The effects are already visible and will be catastrophic unless we act now. Through education, innovation and adherence to our climate commitments, we can make the necessary changes to protect the planet. These changes will also provide huge opportunities to modernize our infrastructure which will create new jobs and promote greater prosperity across the world.

Individuals and governments should take several actions to reduce climate change such as switching to renewable energy, which is in transition from fossil fuels to solar, wind, or nuclear energy sources. We can also strive to change transportation habits in the sense that people use public transport, cycle, or switch to electric vehicles to cut emissions from travel. Reducing waste by using reusable bags, bottles and containers instead of single-use plastics. Supporting reforestation should also be part of the actions that individuals need to take into consideration, planting trees and restoring forests to absorb carbon dioxide.

These collective efforts and many more examples that are not mentioned above can significantly impact global emissions
