- WillAdams 2y agoNo one is debating that the earth in the past was much hotter, and far less hospitable than it is today. The issue here is that modern society was built with certain expectations of certain temperature ranges, and by burning petrochemicals and adding carbon to the atmosphere we have increased the hot house effect of CO2 in the atmosphere beyond the ability of the planet to absorb it, resulting in a net average increase in temperature on a global scale. A layman's understanding of this: - burning fossil fuels adds CO2 and CO to the atmosphere - increased CO2 levels in the atmosphere increases the "greenhouse effect" --- this is easily proven with a science experiment 4th graders can do - the added solar gain increases the temperature of the planet beyond what can be radiated out into space for that portion of the planet rotated out of the sunlight - no one has been able to demonstrate that this additional solar energy is doing anything other than warming the planet --- if it isn't doing so, please explain in plain, simple words where this added energy is going and what it is doing
- jeltz 2y agoThere have been bigger increases but most likely not faster ones though I am not sure how far back we have reliable data for rate of increase. And even if so this rapid rate of increase is still not a good thing. It will require expensive adaptations and lead to extinctions.
- aeonik 2y agoIt's possible there were higher spikes in the past, but I would guess that they were all pretty dramatic events, and yes the earth used to be much hotter in the past. This is obvious if you think about it, all that carbon in the ground had to be in the air before photosynthetic life. And before any life, the Earth was a molten ball of liquid rock. https://en.wikipedia.org/wiki/Paleoclimatology https://en.wikipedia.org/wiki/Paleoclimatology
- dghughes 2y agoYes the Earth was molten magma 4.5 billion years but that's not included.
- abenga 2y agoThe only time scale we care about is the duration human beings have been around. You know the planet being fine it's humans we are worried about and all that jazz.
