global warming and its impact Flashcards
is the long-term rise in Earth’s average surface temperature caused by
the accumulation of greenhouse gases in the atmosphere.
Global warming
is a natural
phenomenon in which certain gases in Earth’s
atmosphere trap heat from the sun, keeping
the planet warm enough to support life
greenhouse effect
Human reliance on fossil fuels like coal, oil, and natural
gas for electricity, transportation, and industry is a major contributor to global
warming.
Burning of Fossil Fuels
Large-scale cutting of forests for agricultural expansion, urban
development, or timber reduces the number of trees available to absorb carbon
dioxide from the air.
Deforestation
The agricultural sector contributes to global warming in multiple ways.
Agriculture
Improper handling of waste, especially organic materials like
food and plant matter, results in significant methane emissions when the waste
decomposes in landfills.
Waste Management
is a key driver of carbon dioxide
emissions due to the widespread use of vehicles powered by gasoline and diesel.
Transportation
- Rapid urban development increases energy demand for construction,
transportation, and infrastructure.

Melting glaciers and thermal expansion of saltwater are
causing sea levels to increase, endangering coastal towns.
Rising Sea Levels:
Hurricanes, droughts, and floods are becoming
more frequent and intense, disrupting people’s lives and businesses.
Extreme Weather Events:
Many species are on the verge of extinction as a result of
habitat loss and shifting weather patterns.
Biodiversity loss:
Heatwaves, vector-borne illnesses, and pollution all pose _________
throughout the world.
health risks
a significant consequence of global
warming, contributing to rising sea levels and altering ecosystems worldwide.
