WHY DOES IT MATTER?
Climate Change is impacting all living things on planet Earth. It is the biggest problem we have. There are many causes to it. Read more to find out.
We are facing a massive threat and rapid attention and action is necessary. If we continue with our current path, scientists say that the consequences will be devastating, having implications on where we live, how we grow food and other services vital to our well-being. A 2 °C increase could mean more heat waves, more extreme weather, a wipe-out of the world's coral reefs, home to millions of species, and eventually, it could lead to conflict and wars over resources.
Excess carbon dioxide can only go into the air and the surface of the ocean. This makes the oceans acidity levels to rise. Marine animals, including coral reefs, are dying off because of this increase.
We depend on Earths polar caps to reflect the sun's heat back to space. This helps cool the planet. But, due to global warming, these polar caps are melting, leading to higher sea levels.
Polar Bears Drowning
Struggling polar bears are the icon for a melting Arctic. Not just them, but many other species, are dying off or being pushed to migrate.
The warmer the climate is, the more water evaporates from the ocean, which makes rainstorms more intense. Huts hurricanes can grow larger, and they can travel farther. At the warmer parts of the planet, it gets extremely dry, which means more droughts, heat waves, and larger forest fires.
Bleached Coral Reefs
Coral and algae depend on each other to survive. Changes in ocean temperature, pollution, overexposure to sunlight, and air exposure during extremely low tides cause the algae to stress and leave the coral. This leaves the coral bleached and vulnerable.
As glaciers melt in the Arctic, they turn into seawater. In cities, tides rise up, sometimes creating floods. This will continue to go on.
Why is this happening?
Evidence shows that human activities, especially emissions of heat-trapping greenhouse gases from fossil fuel combustion, deforestation, pollution, and land-use change, are primarily responsible for the climate crisis. The amount of carbon dioxide in the atmosphere has increased by about 40% over the industrial era. This change has intensified the natural greenhouse effect, driving an increase in global temperatures. Rapid changes like these are unprecedented in the history of Earth.
