WUWT
However, Excess Winter Deaths are not the worst threats to humanity. The
glacial cycle averages about 100,000 years, consisting of about 90,000
years of the glacial period, when mile-thick continental glaciers
blanketed much of the Northern and Southern Hemispheres including
Canada, Russia, Northern Europe and Northern USA, and about 10,000 years
of interglacial, the warm period of the present. Earth is now 11,500
years into the current warm interglacial, and our planet may re-enter the glacial period at any time. ......
Increased atmospheric CO2, driven by fossil fuel combustion
and/or other causes, will have little impact on the onset of future
glaciation. Climate is not highly sensitive to increasing atmospheric CO2. Paradoxically, CO2 concentrations are not alarmingly high; in fact, atmospheric CO2 concentrations are alarmingly low – too low for the long-term survival of terrestrial life. Photosynthesis of C3 food crops ceases at 150ppm – CO2 starvation."

Activist biologist filled with eco-anxiety shares unfounded fear of polar bear catastrophe
WUWT
Misplaced eco-anxiety that kids have about polar bears starts with activist biologists like Steven Amstrup, spokesperson for an organization devoted to raising climate change alarm – and media outlets like The Guardian who help them spread fears unsupported by scientific evidence.
........The truth is, Amstrup has a vested interest in advancing polar bear catastrophe: as I explain in my new book, The Polar Bear Catastrophe That Never Happened (Crockford 2019), he considers his 2007 prediction that summer sea ice decline would decimate polar bear numbers to be a career legacy. He cannot bear to admit he was wrong (no pun intended) . That’s highly unscientific. Yet the media assists him in passing his unfounded eco-anxiety about polar bears on to naïve young children and gullible adults without a word about the current healthy status of the bears."

Water Behaving Badly
WUWT
After 2005 the global ice area went down, but by 2010 it had recovered. From there to 2015, it was above average. And since 2015 global ice area has dropped precipitously but then recovered back to average. Finally, there is no statistically significant trend in the full 1973 – 2019 dataset.
So … lots of things of interest in Figure 3. However, I gotta say, I’m not seeing the evil hand of steadily increasing atmospheric CO2 in that record. Nor am I seeing any “anthropogenic fingerprint”. Perhaps most importantly, am I unable to detect any sign of any “climate emergency” in that record.
The final surprise was the recent several-year deep drop and then recovery of the ice area. I figured it must be from what alarmists have termed the “Arctic death spiral”, the widely trumpeted decrease in Arctic sea ice. So I added the separate Arctic and the Antarctic records to Figure 3 above. Figure 4 below shows those records.
Curiously, the amount of ice at the two poles is just about the same, at ~2% of the globe. But that makes it hard to compare the Arctic and Antarctic ice. So in Figure 4 below, I’ve offset the northern hemisphere (blue line) by 1% for clarity. You’ll need to add 1% to the northern hemisphere ice areas to get the actual values. Figure 4 shows the globe as well as the two halves of the planet separately. Note that in this graphic they are all to the same scale."

Science Vs. The Extinction Rebellion

PODCAST: Dr. Ross McKittrick on climate, hockey-sticks, and Mann
WUWT
Dr. Ross McKittrick of the University of Guelph, Canada, is a professor of economics who got interested in the climate debate after looking over satellite data. He found the climate community very unresponsive and went on his own journey to discover what was up.
He, alongside Steve McIntyre, challenged the famous Hockey Stick paper. Listen in to hear his analysis and why you ought not trust the fraud. Models have to be accurate in their reporting without adjustment by climate pushers."

A Line-By-Line Response to Greta Thunberg’s UN Speech
WUWT
Did you bother to look at any of that science? Thirty years ago they were saying Manhattan would be under water by now. Most every prediction so called “climate scientists” have made during the past thirty years has failed to come true. This is not science being crystal-clear. It is shamanism being crystal-clear. You need to learn the difference. A science that is not able to make what are called “useful, non-obvious predictions” is not science. It’s religion. And, I’m sorry, but you’ve become ensnared in the climate cult’s terrible clutches."

A Climate Modeller Spills the Beans

The climate models are useful tools for academic studies, he says. However, “the models just become useless pieces of junk or worse (worse in a sense that they can produce gravely misleading output) when they are used for climate forecasting.” The reason:
The climate models are useful tools for academic studies, he says. However, “the models just become useless pieces of junk or worse (worse in a sense that they can produce gravely misleading output) when they are used for climate forecasting.” The reason:
These models completely lack some
critically important climate processes and feedbacks, and represent
some other critically important climate processes and feedbacks in
grossly distorted manners to the extent that makes these models totally
useless for any meaningful climate prediction.
I myself used to use climate
simulation models for scientific studies, not for predictions, and
learned about their problems and limitations in the process."
How Many Times do Useless Climate Models have to be Killed before they Die?

Quadrant Online has just published a remarkable article – A Climate Modeller Spills the Beans – in which a highly-qualified climate scientist and modeller makes it abundantly clear that the climate models, as coded and used currently, can never predict future climate."

How to Destroy the Climate Change Hoax
Celebrities, activists, environmentalist organizations, the UN,
government entities and sadly, even the Vatican support the theory that
humans cause climate change. However, in this exclusive interview,
“global warming” expert and author Marc Morano gives you hard-hitting
arguments and facts that dispel the artificial fear propagated by
“climate emergency” alarmists. (YouTube)
No Climate Emergency say 500 Scientists to UN
On the same day that Greta Thunberg made an impassioned speech to the UN
about her fears of a climate emergency, some 500 scientists sent a
registered letter to the UN Secretary-General stating that there is no
climate emergency and climate policies should be designed to benefit the
lives of people. Read the full document and list of names here:

Professor Valentina Zharkova: The Solar Magnet Field and the Terrestrial Climate
"This approach also predicts the modern grand minimum upcoming in
2020-2055. By utilising the two principal components of solar magnetic
field oscillations and their summary curve, we extrapolate the solar
activity backwards one hundred millennia and derive weaker oscillations
with a period of 2000-2100years (a super-grand cycle) reflecting
variations of magnetic field magnitude. The last super-grand minimum
occurred during Maunder Minimum with magnetic field growing for 500
years (until ~2150) and decreasing for another 500 years. The most
likely nature of this interaction will be discussed and used to explain
long-term variations of solar magnetic field and irradiance observed
from the Earth." (YouTube)

No Change In Arctic Sea Ice Extent For Almost 14 Years

There has been little or no trend in Arctic sea ice extent since the start of MASIE records in 2006.

Misinformed Iowa Professors
Tony Hellier
University of Iowa professors Peter Thorne and Jerry Schnoor tell the world that Iowa will get a lot more 90 degree days in the future as a result of Iowa residents emitting CO2. All evidence shows the exact opposite. Average daily maximum temperatures in Iowa have plummeted over the past century.As CO2 levels have increased, the frequency of 90 degree days has plummeted. Peak temperatures in Iowa have plummeted. The number of 100 degree temperature readings in Iowa has plummeted. Iowa’s worst heatwave occurred in 1936, when Logan had 41 days over 100 degrees from June 16 to September 6. Why are public health professors pretending they are climate prophets? They obviously didn’t do any research. Professors Peter Thorne and Jerry Schnoor are simply making numbers up. There is no evidence to back up their claims, and it is absurd to suggest that Iowan’s can control atmospheric CO2 levels – as China and India build hundreds of new coal fired power plants.
