Climate change happens with or without us. That does not mean we should spend trillions of dollars on something that might change the outcome slightly. Change is coming and it is much cheaper and moral to adopt to the changes rather than trying to prevent them.
Climate change has everything to do with our cosmic environment and nothing to do with us as a species. We are living in the most stable climate we’ve seen in over 200,000 years and the temperature average have never stopped fluctuating.
However… the temperature fluctuations have been steadily and slightly getting more erratic from 10,000 YBP to now.
Statistically speaking, our Modern Warm Period is drawing to an end, and we are headed for another glacial period.
About 13,000 years ago, we experienced the Younger Dryas Period. A temperature swing of more than 15 degrees cooler than now.
Between 100-150,000 years ago, we experienced a catastrophic warming of over 15 degrees hotter than now.
I would have hated to have lived during these climatic upheavals, but our species did, and we survived everything the Earth has thrown at us for about 300,000 years, including mass extinction, extreme climate change, cosmic impacts, super volcanoes, etc…
This is why I shake my head when I see liberals crying about a 2 degree warming.

Note the average time spans of inter-glacial periods. It stays colder, longer, because it’s always easier to cool something off than it is to warm it.
Also note that all of the previous inter-glacial periods were as warm, if not warmer than the climate is now.
We have spent the vast majority of our time as a species in very cold times, and the global warming alarmists do nothing to address the heat-energy needed to end the last glacial cycle in under 1,400 years.
When the ice melts in a glass of water, does the level rise? So why should sea levels rise when icebergs melt? Warmer sea temperatures mean more evaporation. I have a 600 litre tropical fish tank - that loses about a litre a week in evaporation. Sea levels could go down, not up.
