Let’s understand what the major causes and effects of climate change are. 

1. Greenhouse Gas Emissions: Due to the extensive use of fossil fuels like coal, petroleum, and natural gases for energy and transportation, the overall CO2 levels have significantly skyrocketed.
2. Deforestation is another major cause of why the levels of CO2 are rising globally. Trees are known for soaking up CO2 and releasing oxygen (O2), and cutting them led to climate change.
3. Urbanization, excess consumption, and waste production cause climate change.

Let’s understand the harmful effects of climate change:

1. Ocean acidification: due to high concentrations of CO2 and other harmful gases, marine life is getting destroyed.
2. Extinction of species: Golden toad (Costa Rica region), Bramble Cay Melomys (Great Barrier Reef, Australia), Pinta Island Tortoise (Galapagos region), and more, became extinct due to hunting, sea-level rise, and loss of food sources.
3. Due to increasing temperatures, the oceans are becoming warmer, and cyclones are known for drawing energy from warm ocean waters.
4. Forest fires are another consequence of climate change. Due to increasing heatwaves, the forests catch fire that leads to loss of lives, natural habitat and public properties. For Example: Australia, California, and Amazon.
