my question is
What is the affect of increasing CO2?:
Increasing carbon dioxide (CO2) levels in the atmosphere is harmful to the Earth because it acts as a greenhouse gas, trapping heat from the sun and causing the planet to warm significantly, leading to climate change with severe impacts like rising sea levels, extreme weather events, disruption of ecosystems, and potential food insecurity; essentially, human activities are enhancing the natural greenhouse effect by adding more CO2 to the atmosphere, causing global warming
In the past 60 years, carbon dioxide in the atmosphere has increased 100-200 times faster than it did during the end of the last ice age.

Now what was the temperature of the Earth 485 million years ago?
According to recent studies, the global temperature around 485 million years ago was significantly warmer than today, with an average estimated to be around 30°C (86°F), indicating a "hothouse" climate with no polar ice caps and warm oceans throughout the globe; this data is based on reconstructions of Earth's past climate using proxy data and climate models.
HMMM... a "hothouse" climate, no ice caps... and this was at 4,000 PPM!
Today "global warming" (now "climate change" believers) say
the most concerning temperature for global warming is 1.5 degrees Celsius above pre-industrial levels, with efforts focused on limiting the increase to this level to avoid the most severe impacts of climate change
Pre-industrial temperature approximately 56.62°
We know all about how the Earth's temperature needs to stay below "1.5° above pre-industrial levels". But what were they? Every news article and policy statement seems to hand-wave it away.

HMMM... so the world's temperature in 485 million years ago was 86° and global warming people are fighting to keep it down by 1.5°?
