Global Warming... no, scientist don't call it this anymore.
Climate Change due to Carbon Dioxide emissions... yes. More CO2 in the atmosphere changes the temperature and moisture retention. Pretty simple.
"How can global warming be real if this winter is seeing record cold?"
When a ice cube melts in a glass of water, the water get colder.
In the summer the Earth is closer to the sun and tilted so that the northern hemisphere is facing it, with more CO2 in the atmosphere evaporated water stays up there longer and forms bigger clouds/storms. (Also more water compared to salt in the ocean makes for a bunch of other factors)
Infrared light from the sun is trapped with more CO2, meaning slightly warmer temperatures, melting more polar ice than pre-industrialism.
This is where the glass of ice water comes in, as the ice melts the ocean gets cooler around the northern ice cap. When winter comes the earth goes further away from the sun but the cooler water around the northern ice cap remains and creates harsher winters.
So it just so happens that these changes came about the same time as industrialization? Sure.
Here's an experiment you can do if you don't "believe" in global warming. Park your running gasoline powered car(emissions simulator) in a garage (experimental ecosystem) with the door closed (green house) and see if the biodiversity in the garage is challenged to survive.
Science isn't like religion: even if you don't believe, it still exists.
I would cite regulation, but I know you will simply ignore it.
