Global Warming
- GLOBAL WARMING occurs when CARBON DIOXIDE (CO₂), METHANE (CH₄), and other GREENHOUSE GASES accumulate in the atmosphere and trap the Sun's heat.
- The Earth's climate is a balance of the ENERGY it receives from the SUN and the energy it radiates back into space. When this balance is upset by excess greenhouse gases, global TEMPERATURES RISE.
- These gases act as an INSULATING LAYER, similar to the glass of a greenhouse, allowing sunlight in but preventing the heat from escaping, hence the term GREENHOUSE EFFECT.
- Without this natural greenhouse effect, Earth would be too cold for most forms of life. However, human activities have increased this effect, leading to climate change.
Consequences of an Enhanced Greenhouse Effect
- SEA LEVEL RISE: The melting of ice caps and glaciers contribute to rising sea levels, threatening coastal communities and ecosystems.
- INCREASED FLOODING: A higher sea level increases the likelihood of severe flooding. This can result in damage to infrastructure, loss of habitat for wildlife, and destructive effects on human settlements.
- SHIFTING ECOSYSTEMS: As global temperatures rise, ecosystems can change. Some species may find their current habitats unsuitable and move to cooler areas, if available.
- ALTERED SPECIES DISTRIBUTION: Many species are shifting to higher altitudes where temperatures are cooler, altering ecosystems and food webs.
- CHANGES IN AGRICULTURE: Some regions may become more suitable for agriculture, while others may become less so, affecting food security and economies.
- HEALTH IMPACTS: Higher temperatures can lead to increased incidences of heat-related illnesses and can affect disease patterns globally.
- BIODIVERSITY LOSS: Species that cannot adapt or migrate to new habitats may face extinction. This loss of biodiversity can disrupt ecosystems.
