The last IPCC report, AR4, stated that it was “very likely” that they were full of bat guano, er, that Mankind was at fault for the tiny bit of warming (mentioned in the AP report) since the Little Ice Age, now…
(USA Today) Global warming is “unequivocal” and it is “extremely likely” that humans are the primary contributors to this warming, according to a report released Friday morning in Stockholm by the U.N.-created Intergovernmental Panel on Climate Change (IPCC), the world’s top climate research group.
“Human influence has been detected in warming of the atmosphere and the ocean, in changes in the global water cycle, in reductions in snow and ice, in global mean sea level rise, and in changes in some climate extremes,” the report says.
I’ll agree that Mankind has some small influence, perhaps 10-15%, mostly from agriculture, landfills, land use, and the Urban Heat Island Effect, but, sea rise is well within the norm of the average for the last 7,000 years (this is when the monster sea rise from the end of the last glacial age slowed down), meaning that this is a light warm period. It has not accelerated. As for the rest, no big deal, either. It’s what is expected during a warm period.
The report says that it is now more certain than ever that “human influence has been the dominant cause of the observed warming” since the 1950s.
Which is funny, considering that the 1950’s through late 1970’s was a period of cooling. Remember the articles wondering if the earth was heading towards a new ice age? Perhaps the IPCC could explain the extreme warmth of the 1930’s? And rising temps post Little Ice Age?
The report says that “each of the last three decades has been successively warmer at the Earth’s surface than any preceding decade since 1850” and that in “the Northern Hemisphere, 1983–2012, was likely the warmest 30-year period of the last 1400 years.”
Well, duh. That’s what happens when a warm period follows a cold period. Does. Not. Prove. Causation.
As for the supposed “pause” in global warming since 1998, the report says that this may be due to changing climate models and that a fuller understanding of this pattern requires further study.
So, it’s now caused by faulty computer models? Seriously? That’s the tactic they’re taking? Oh, and that they don’t know what’s going on? What makes them think they know for the rest?
This all comes from the summery for policymakers, and prognosticates a temperature rise by 0.3 to 4.8 degrees C by the end of the century unless Government puts in massive controls on your life with lots of taxes and all the other things they’ve been pushing. That’s 0.5-8.6 F. That’s one whopping difference in prognostication, wouldn’t you say? Unless you’re forced to give up your fossil fueled lifestyle, we’re all going to burn and be flooded and live in drought and see more snow and ice and experience more earthquakes and volcanoes. Doom! Now watch the Warmists fly off in droves in fossil fueled vehicles for a nice working vacation in Poland for this year’s IPCC COP19.

Regarding your silly picture. You do understand that CO2 is colorless and odorless, right? And I typical coal-fired power plants emits plenty of it in addition to steam (H20).
You’re a bit confused here. Recent reconstructions of the Holocene temperature record (Marcott et al., 2013) show a slow, long term cooling trend where estimated global temperatures have declined about 0.6C from the peak of about 5000 yrs ago. In the past century or so the avg global temperature has increased that much and man-made global warming is just getting started. All of human civilization evolved within a global temperature range of 0.6C and we’re looking conservatively at a 2C increase within this century. Strap in, it’s likely to be a bumpy ride for your grandchildren, great-grandchildren and great-great grandchildren. I’m sure they’ll thank us later for living it up at their expense!
(By the way, the Marcott reconstructions show MORE natural variability in the temp record than was previously described.) The Marcott data also correlates well with the PAGES 2k land-only reconstructions independently derived.

Abstract:
“Surface temperature reconstructions of the past 1500 years suggest that recent warming is unprecedented in that time. Here we provide a broader perspective by reconstructing regional and global temperature anomalies for the past 11,300 years from 73 globally distributed records. Early Holocene (10,000 to 5000 years ago) warmth is followed by ~0.7°C cooling through the middle to late Holocene (<5000 years ago), culminating in the coolest temperatures of the Holocene during the Little Ice Age, about 200 years ago. This cooling is largely associated with ~2°C change in the North Atlantic. Current global temperatures of the past decade have not yet exceeded peak interglacial values but are warmer than during ~75% of the Holocene temperature history. Intergovernmental Panel on Climate Change model projections for 2100 exceed the full distribution of Holocene temperature under all plausible greenhouse gas emission scenarios."
Have the paleocons performed any long-term reconstructions that differs from this result?
Since the Earth has been gradually cooling since about 5000 yrs ago (naturally, I might add) to what physical mechanism do you attribute your purported "natural" rise in sea level up to about a century ago? We know that water expands with warming and that land ice can melt with warming. How do we get more water with cooling?
