Climate change is not something that can be denied

In recent political debates, a common topic has been global warming.

As a Laguna Middle School student who likes politics, I find this topic very interesting.

When I logged onto my computer after school, I was curious why people believe climate change doesn’t exist. One repeating topic that I found was, “Polar bears are thriving!” But in fact, the Arctic is one of the worst places to be affected by global warming.

Arctic ice is melting so rapidly that by 2040, the region is expected to have a completely ice-free summer.

In fact, about 1 million square miles of arctic has melted since the 1970s. Many Republican presidential candidates do not believe global warming is made by human actions, although 97 percent of climate scientists agree that climate change is a result of humans.

Sea levels have risen, along with global temperatures. Carbon dioxide also has risen since the Industrial Revolution, which dates back to the 18th century and the Second Industrial Revolution in 19th century. In conclusion, global warming is a thing we should be taking care of — not denying.
