How Much Warming Can Earth Take?

I came across this graph of the historical temperature. In the distant past, during the Eocene, which is when mammals first began to evolve, the earth was actually as much as 25 degrees Fahrenheit (14 Celsius) warmer than it was today. Even if the temperature models are correct, this is 17 degrees Fahrenheit (9 Celcius) warmer than the temperature they predict in 2100.

This makes the claim that we are crossing a tipping point to catastrophic warming that will make the earth uninhabitable seem pretty questionable. If the models are correct and we shift the earth’s temperature by 8 degrees Fahrenheit in only 100 years, it will be the relatively short time (a mere moment, in geological time) that causes grief, not the resulting temperature. In the past, changes of this magnitude have occurred over tens of thousands of years, giving the biome time to adapt gradually.

  1. When interested in environment and when believing in only One True God, the Gdo of Israel, why not sharing your thoughts of how to live in this world and how to respect the creation of the Most Divine Elohim Hashem Jehovah on From Guestwriters?

      Paul said “Who has known the mind of god?” Applying Jesus’s teaching is difficult in this case. Is it better to take drastic actions that can place a terrible burden on the poorest among us, or to risk future generations? But, as usual, if you think about it, the answer is clear. Avarice is the root of the problem. We all need to use less. Perhaps the fact that humanity will soon cease to multiply upon the earth is a sign that we have not learned our lesson in time. I choose to hope that it is still possible to bring about the kingdom of heaven on earth.
