Check out the TED-Ed Clubs YouTube channel: Throughout Earths history, climate has varied greatly. For hundreds of millions of years, the planet had no polar ice caps. Without this ice, the sea level was 70 meters higher. At the other extreme, about 700 million years ago, Earth became almost entirely covered in ice, during an event known as Snowball Earth. What causes these swings in the planets climate? Lorraine Lisiecki investigates. Lesson by Lorraine Lisiecki

So if man is the main reason for the climate changing then what caused all the other endless climate changes and ice ages in Earths history, how about that big thing in the sky, commonly known as the sun. The most massive and powerful object in the solar system plays a far bigger part on Earths climate than any other factor outside of Malankovich cycles. All your are doing is pushing man made global warming.

This video is pure BS. Norway for instance has had it's coldest July in 60 year, and down under there has been heavy snowfall in places like Australia, Argentina and Brazil. Explain that? If it wasn't for the industrial revolution, the amount of CO2 in the atmosphere was dangerously close to dip below 200ppm, at which point all plant life on earth would come to a grinding halt.
reply

Our present atmospheric CO2 (2020) is 418 parts per million and at 150 parts per million all plants on the planet die. The question: just where during this video do people turn off their brain cells and not understand just how good 418 ppm CO2 has been for our plants?
reply

No doubt they will say anthropomorphic global warming led to the ice sheets melting and a shut down of the Gulf Stream which ushered in the new unnatural ice age! Its happening on cue though. was it anthropomorphic all the others times too?
reply

If wed not released that much CO2 wed run into an ice age faster. Is that what you are saying? If yes, do you think an ice age would be preferred to a warm period for humans and life in general?
reply

That means this is actually a cooling period for earth and still because of our actions we are feeling warmer Warmer day by day. I wonder how would it be if the period shifts to hot.
reply

Fact: there is no fossil fuel. Instead our earth produces it naturally, just like how it produces everything else. How else would fossil fuel get here? Our earth makes it
reply

funny because now I am seeing more and more talk about Global cooling and an impending new ice age. Best to disregard all of this and just live your life.
reply

its minimally caused by co2. the main factor is the axis rotation and it is periodic. theyre really pushing the narrative that we are the problem lmao
reply

California hardly has any snow where I live, I wish COVID never happened, then we wouldn't have to do social distancing and wear face masks.
