That was over 10,000 years ago. Holocene temperatures have been very stable.
What is their plan to stop the Earth from recovering from the last Ice Age?
The last vestiges of the LIA may have persisted into the early 1900s.
And temperatures are one thing; corals are also imperiled by ocean acidification.
So, is it your contention that this supposed ocean acidification is the Fault of Man? That somehow, since it is All Our Fault, that we will be able to stop the process?
How can you call the Holocene stable when, in the same post, you refer to the Little Ice Age lasting into the 1900s - and which was preceeded by the Midieval Warm period?
During the Holocene, there have been several warm-cold cycles with a periodicity of around 1500 years. The cold phases have been relatively abrupt, and each lasted several centuries before an apparently rapid switch back to warmer conditions.
If you want to call that stable, then temperatures today are stable, too.
