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.

The really sad part is that most people in developed nations won't care until it directly affects them. Some won't care even then.

Just some few weeks agos one plaque was put too to declare the death of the Ayocolo Glaciar, in the Iztazihuatl volcano, in Mexico :(

That memorial to a glacier is one of the most sobering, depressing things I've seen recently

This is the saving grace for all students taking online classes right now. I cannot be more grateful.

You need to make a whole course on climate change
@pablovan2675 2 years ago

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!

Such an important message. Thank you for sharing and simplifying it.

I wish that you went more in depth about methane and nitrous oxides role in global warming; which are vastly overlooked despite playing a major in it

Best crash course episode I have ever watched.

8:41 is not correct. Annual average global temp, increased 1.2°C or 2.1°F from 1880 year to today not 0.3-0.6°C (0.5°F - 1.1°F) as is stated at that mark.

I was lucky enough to go hike on Solhiemjokull in Iceland in 2017. They had markers set up on the walk to the glacier showing where it was in years past. It was a stark and enlightening experience.

“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

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.

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!!!!!!!!!!!!

I recently made a program for showing how climate change has affected an area based off of weather station reports from 1950 to modern day. It, to the surprise of very few people, showed an increase in temperature of 1-2 degrees almost everywhere. Except Calgary.

It's not the environment that's in danger, but us 😉
