CrashCourse 
Today we’re going to talk about climate change which is when there is a change in the average weather patterns in a region over a long period of time – these changes can be natural or human-caused. We’ll discuss the main driving forces of climate change in the past and show you how what’s happening now is unlike anything in the past. Global warming, or when there is an increase in the average surface temperature of the planet, has been well-documented since the Industrial Revolution, and scientists have concluded that there is a 95% probability that human activities like burning fossil fuels, industrialization, modern agriculture, and deforestation have caused most of this most recent warming. And while individual actions do matter in helping to curb the disastrous implications of a warming planet, it’s also up to us to hold corporations and governments responsible for the policies and the large-scale emissions that play a disproportionate role in impacting our atmosphere and climate.

About The Author
You say "almost all of the warming was caused by humans" – could you expand on that? I learned that we even caused more than the visible warming, because naturally causes would actually be cooling the planet a little bit, right now.

Your data is a little old. Global average temperatures have already risen by more than 1°C (1.84 °F) from baseline 1951-1980 mean [https://climate.nasa.gov/vital-signs/global-temperature/ ], we already passed the mark of 415 PPM of CO2 [https://www.esrl.noaa.gov/gmd/ccgg/trends ], and we are on track for about 3-4°C by the end of the century.
Best crash course episode I have ever watched.
I love this series. Thankful to be a geographer myself 🙂
If you are looking for a way to help the environment you can use ecosia they are a search engine that plants trees
Wow I just happened to look this up for a class. I didn't realize this is literally just came out. I am glad to see this on crash course but also can't help but think they could have a whole course on human impacts on the environment, ecosystems, biodiversity, land use, resource extraction, levels of consumption, lack of reusable products, and much much more. Sustainability is one word for it, but sustainability is not just about the environment and climate, it is about how we set up our social, financial, agricultural and resource systems. I would love to see crash course do something like that. If anyone I believe crash course can. If agree please up vote and maybe they will see!
Truthful video with evidence about climate change: exists
Climate deniers: "Time to ruin the video so we can get a comment with likes haha"
I am watching this video before going on vacation. This video is really inspiring and I am now deciding to put a reusable water bottle and a plastic bag for toothbrush made from packaging waste in my suitcase IT IS NEVER TOO LATE TO HELP IN 2021!!!!!!!!!!!!
Can you make a video explaining the Great Recession in 2008? Please!!!! I love you’re videos and I would really like to Learn more about that
Very sad.
Thank you for keeping up the good fight.
Might help to present to people what are the causes and effects of climate change in their area, even down to the neighborhood level. People locally better able to grasp and deal with climate change.
My favorite channel ever!
“It is increasingly clear that we are living through the sixth major mass extinction. Freshwater microbial blooms, wildfires, coral bleaching and spikes in ocean temperature are becoming more frequent and intense in our warming world. Where along the extinction-event spectrum the present warming will place us is, for the first time in Earth’s history, up to just one species.” – Scientific American, July 2022
It's not the environment that's in danger, but us 😉
This is amazing for my school because I need to do a project😯😛
This thing is good
hello
The problem is human greed knows no bound. The solution is already in plain sight but it's just hard to let go of those multi billion profits. For God's sake we are all just fleeting travelers in time, yet some people act as if they're immortals!
When glaciers advance and the climate is colder, glaciation occurs and the sea level drops. And when the climate is warmer, glaciers retreat and sea levels rise.
it was amazing, really i bow head
Guys at crash course thank you for making us learn in fun🎉
