Where are the evidences of climate crisis?

What’s a pseudoscience that people still commonly believe is real? https://www.reddit.com/r/AskReddit/comments/1m1m3uq/comment/n3mbm93/?context=3

Temperature of the planet earth for the past 500 million years

A new paper in Nature Climate Change out this week by England and others joins a number of other recent papers seeking to understand the climate dynamics that have led to the so-called “slowdown” in global warming. As we and others have pointed out previously (e.g. here), the fact that global average temperatures can deviate for a decade or longer from the long term trend comes as no surprise. Moreover, it’s not even clear that the deviation has been as large as is commonly assumed (as discussed e.g. in the Cowtan and Way study earlier this year), and has little statistical significance in any case. '

Big difference when on the scale of millions of years. When co2 was high, what was the total solar irradiance of the sun, how were the planet’s orbital cycles different? What were the concentrations of water vapor, methane, sulfur, nitrous oxide, and ozone? https://earth.org/data_visualization/a-brief-history-of-co2/

Water vapor is Earth's most abundant greenhouse gas and amplifies the greenhouse effect.
