Nope.
Temperatures fluctuate wildly on Earth for reasons that are simply not understood.
One of the more recent intriguing findings is the remarkable speed of these changes. Within the incredibly short time span (by geologic standards) of only a few decades or even a few years, global temperatures have fluctuated by as much as 15°F (8°C) or more.
For example, as Earth was emerging out of the last glacial cycle, the warming trend was interrupted 12,800 years ago when temperatures dropped dramatically in only several decades. A mere 1,300 years later, temperatures locally spiked as much as 20°F (11°C) within just several years. Sudden changes like this occurred at least 24 times during the past 100,000 years. In a relative sense, we are in a time of unusually stable temperatures today—how long will it last?

As you can see, temperature changes fluctuate wildly, jumping as much as 20°F within a few years for no apparent reason, and scientists are at a loss to explain why.
The IPCC has no interest in those facts or the reality, because its constitution mandates that it study only man-made global warming to the exclusion of all other possibilities.
That would be tantamount to cancer researchers limiting their research to only benzene as the cause of cancer, while excluding the possibility, and the fact, that other organic compounds, like unsymmetrical dimethyl hydrazine cause cancer, that there are genetic causes of cancer, and that there are environmental and life-style factors that can cause cancer.
The reality is that if you never burned a single ounce of fossil fuels, you would still be experiencing global warming, and the Greenland Ice-Sheet would still nearly melt in its entirety, causing sea levels to rise at least 30 feet.
That is what
always happens during an Inter-Glacial Period.
You are subscribing to the false belief that during an Inter-Glacial Period, the average global temperature
should be 56.8°F.
There isn't a single shred of evidence to support such a false belief.
The historical record of Earth's climate provides irrefutable proof that average global temperatures are significantly higher than present, during an Inter-Glacial Period.
If the average global temperature increases another 7.8°F, there is absolutely nothing abnormal about that, because it already happened.
And if the average global temperature increases another 15.3°F, there is absolutely nothing abnormal about that, either, because it, too, has already happened.
What is perfectly normal is for the average global temperature to increase to a point where it falls in the range 7.8°F to 15.3°F, because that is historically what happens.
And contrary to the false Doom & Gloom claims of the global warming crowd, a warmer Earth does not result in the massive destruction of habitat or expanding desertification.
It's exactly the opposite.
As Earth becomes warmer, it becomes wetter, not drier.
When the average global temperature of Earth was in excess of 90°F, the entire Earth was a lush tropical rain forest. Tropical rain forests covered all of Africa, all of Europe, all of Asia including Siberia, all of Alaska, Canada and the United States down into Central and South America.
We know this to be true, because the fossil record of tropical flora and fauna proves it.
Primates evolved in African tropical rain forests and migrated throughout Europe and Asia, but not the Americas.
Then there was a massive volcanic eruption on the scale of the Deccan Traps lasting about a Million years. It created a land-bridge between Scandinavia and Canada, and primate species crossed this land-bridge, populating the tropical rain forests in Alaska, Canada, the US, and Central and South America.
We know this to be true, because the fossilized records of various primate species have been found in Alaska, Canada and the US, and because there are still 8 primate species living in the jungles of Honduras, Guatemala, Nicaragua and Brasil.
Eventually, tectonic plate action and natural processes destroyed the land-bridge, and Earth's climate also cooled. That destroyed the tropical rain forests of Europe, most of the rain forests of Asia, all of the rain forests in Alaska, Canada and the US, and most of the rain forests in Central and South America, resulting in the extinction of dozens of primate species. Had that not happened, it's quite possible both great apes and hominids would have evolved in the Americas.
The point is that when global temperatures rise, it results in the destruction of the ice-sheets, glaciers and pack, increasing the sea levels.
The increase in sea levels also results in a corresponding increase in the surface area of the oceans.
The increased surface area of the oceans does not cause the rate of evaporation to increase, but it does result in more water being evaporated. That water vapor is precipitated out as rain.
Rising temperatures are beneficial, not harmful.
You can look forward to that, and this:
CP - Abstract - How warm was Greenland during the last interglacial period?
8.5°C corresponds to 15.3°F warmer.
7.5°C corresponds to 13.5°F warmer.
At the end of the last Inter-Glacial Period, there was neither an ice-sheet nor a glacier on Greenland; it was nearly totally ice free. All that was left was a very large "snow bank" that snaked along the west side of the mountains on the east coast.
I used to post an image of what is left of the Greenland Ice Sheet, but people didn't like it and kept reporting it, and so it kept getting deleted, but you can see it here:
