CLIMATE CHANGE: CAUSES, CONSEQUENCES AND SOLUTIONS

Аннотация

Climate change is one of the biggest problems facing our world today. This article looks at the main causes of climate change, including pollution from factories, cars, and the cutting down of forests. It also explains how climate change is affecting the Earth, such as rising sea levels, heatwaves, stronger storms, and threats to animals and human health. In addition, the article discusses how climate change is unfair to poorer countries and how it affects people's mental health. The article ends with solutions, including clean energy, better environmental laws, and small actions we can all take to help. The goal is to raise awareness and encourage everyone to take part in protecting the planet.

The term "climate change" refers to long-term alterations in temperature, precipitation patterns, and the frequency of extreme weather events. These shifts are largely attributed to human-induced factors such as the burning of fossil fuels, deforestation, and industrial emissions. According to the Intergovernmental Panel on Climate Change (IPCC, 2021), the Earth's climate system is experiencing unprecedented changes that are intensifying each year. The urgency of addressing climate change is no longer a matter of future concern — it is a contemporary crisis with far-reaching consequences. Causes of Climate Change: Climate change is predominantly driven by anthropogenic activities. Among these, the burning of fossil fuels such as coal, oil, and natural gas for electricity, heating, and transportation remains the chief contributor. These activities release enormous quantities of greenhouse gases (GHGs), especially carbon dioxide (CO₂), into the atmosphere. GHGs trap heat in the atmosphere through the greenhouse effect, leading to global warming. Another significant contributor is deforestation, which reduces the planet’s capacity to absorb CO₂. Forests act as carbon sinks, and their removal not only increases atmospheric CO₂ levels but also disrupts biodiversity and water cycles. The expansion of agriculture, logging, and urbanization accelerates this process. Moreover, industrial activities and vehicular emissions release not only CO₂ but also methane (CH₄), nitrous oxide (N₂O), and other harmful gases. These emissions contribute to ozone depletion, acid rain, and air pollution, which collectively worsen climate-related problems. The dumping of industrial waste into oceans also threatens marine ecosystems, jeopardizing species that are already endangered. As NASA (2022) notes, these human activities form a feedback loop of environmental degradation, making it increasingly difficult to restore ecological balance. Consequences of Climate Change: The impacts of climate change are both global and local, affecting every continent and ecosystem. The most visible effect is https://scientific-jl.org/obr Выпуск журнала №-73 121 Часть–1_ июл–2025 ОБРАЗОВАНИЕ НАУКА И ИННОВАЦИОННЫЕ ИДЕИ В МИРЕ 2181- 3187 global warming, with the Earth's average surface temperature rising by approximately 1.1°C since the pre-industrial era (IPCC, 2021). If current trends continue, temperatures may increase by 3.7°C to 4.8°C by the end of the century — far surpassing the 2°C threshold many scientists consider dangerous. One immediate result of this warming is accelerated glacial and polar ice melt, which contributes to rising sea levels. NASA (2022) reports that sea levels have risen more than 20 centimeters since 1900, endangering low-lying coastal regions with frequent flooding and land erosion. The loss of biodiversity is another critical consequence. Arctic species, such as polar bears, are struggling to survive as their habitats vanish. In tropical regions, coral bleaching and ecosystem collapse are threatening marine and terrestrial life. Climate change also intensifies extreme weather events — hurricanes, droughts, wildfires, and heavy rainfall are becoming more frequent and severe. These disrupt agriculture, displace communities, and increase the risk of disease. The Food and Agriculture Organization (FAO, 2020) warns that global food security is at risk, particularly in vulnerable regions such as Sub-Saharan Africa and Latin America, where climate variability leads to crop failures and water scarcity. Solutions and Mitigation Strategies: Despite the alarming trends, effective solutions are available. The most critical step is a transition to renewable energy sources, including solar, wind, hydro,
