Climate change is a serious issue that cannot be denied as factual with how much evidence we have for it.
Here are some crucial pieces of evidence listed below.
First of all, the global temperature in 2020 tied with 2016 as the hottest year in recorded history. Below showing this with more visuals
is
an animation I found on the climate.gov website.
The average temperature worldwide has increased by around 2 degrees fahrenheit since 1980. This is a rather short period of
time for such dramatic increase. It may really not seem dramatic until you take into consideration how much heating it takes
to warm up all the oceans by 2 degrees, and that should be very concerning to anyone who lives on this planet.
In the photo below we can see that carbon dioxide levels in our atmosphere are much higher than they've ever been. This is mostly from
human's burning of fossile fuels, which releases more gases in the atmosphere that trap the heat at the Earth's surface, trapping the heat
in with it. This is called the greenhouse effect.
