Could you list your sources? And do you know any specific things that the humans did to create climate change 1,300 years ago?

As the population rises the more fossil fuels we burn and the more pollution we create, yes natural occurrences create climate change but humans are affecting it drastically more and more each day.

I agree with your comment because there is always two sides - it isn't all humans doing, there is natural causes. its a fact. And I agree with your last few sentences because yeah, who knows. The universe may have other things in store for the planet, we might just be a phase.

Rising levels of human-produced gases released into the atmosphere create a greenhouse effect that traps heat and causes global warming

2010 Anderegg study found that 97-98% of climate researchers publishing most actively in their field agree that human activity is primarily responsible for global climate change

Over the 20th century, global temperatures rose 1.4F cause of humans burning fossil fuels

Rising levels of atmospheric greenhouse gases are a direct result of human activities such as burning fossil fuels which causes significant and increasingly severe climate changes (global warming, loss of sea ice, sea levels rise, stronger storms, and more droughts).
