What remains uncertain is how these increases of carbon dioxide– an important greenhouse gas– and other human impacts such as land use changes will react with naturally occurring climate forces and variability in the future. Predictions of global temperature increases vary, but various modeling scenarios run for the Intergovernmental Panel on Climate Change ( IPCC) suggest a range of global warming of between 2.5–10.4°F by 2100. How these changes will impact regional climate and hydrologic dynamics is also largely uncertain.
Quick quiz for IPCC gurus. Temperatures have not increased at all this century. If the current temperature decline continues, how long will it take to reach 2.5F warming? How long will it take to reach 10.4F warming?
Temperatures rose about 1F over the last 150 years, so it makes perfect sense to forecast 10.4F warming over the next 90 years. If you have the IQ of a snail.

lol, I like the way they nailed down their prediction. Between 2.5 and 10.4……… that’s what I like about climate science, it is so exacting!
quite a range of estimates. too bad mikey wont give up the code, it was accurate to 0.01 degree over a thousand years.
Amazing how they can get to such a gnat’s a$$ backcasting, but forecasting, wwaaayyyy different.
You shouldn’t insult snails like that.
And unlike the IPCC, they are harmless and beneficial.
The recent news that ice cores taken in Greenland from over a mile and a quarter deep found butterflies and such, a lush forest environment that is buried under all that ice tells us a lot doesn’t it? I think the graph we have seen that shows current times are cooler than most of the past 10,000 years is pretty well confirmed. If only man made global warming was true. We were so lucky to live in very moderately warm times, at the declining end curve of mostly warmer times like the Medieval warming was, and the cold is going to return. One day, history books may well record a date from our current times as the end of the Holocene interglacial. The Japanese climate science project that tied the geological indicators together and proved that deep solar quiet gave us more precipitation and the Little Ice Age is another important piece in the puzzle and we owe them a lot of credit for it.
Mr. Goddard, mark this prediction down for future reference:
Well, they’ve got off to a good start I see.

Your chart doesn’t look like the one recently published in the Washington Post. The Post would never tell a lie!!
