Tamper, tamper! How They failed to hide the gulf between predicted and observed warming

by Christopher Monckton,  January 3, 2018, in WUWT


The indefatigable Roy Spencer at the University of Alabama at Huntsville is the first to declare the global temperature anomaly for December 2017. As Fig. 1 shows, in the 39 years 1 month from December 1978 to December 2017, the planet has warmed by half a Celsius degree. But that is equivalent to 1.28 C°/century, or little more than one-third of the 3.3 C°/century predicted with “substantial confidence” by IPCC in 1990 and also by the fifth-generation general-circulation models of the Climate Model Intercomparison Project in 2013.

150 NON-Global Warming Graphs From 2017 Pummel Claims Of Unusual Modern Warmth

by K Richard, January 1, 2018 in NoTricksZone


In the last 12 months, 150 graphs from 122 peer-reviewed scientific papers have been published that undermine the popularized conception of a slowly cooling Earth temperature history followed by a dramatic hockey-stick-shaped uptick, or an especially unusual global-scale warming during modern times.

Yes, some regions of the Earth have been warming in recent decades or at some point in the last 100 years.

Some regions have been cooling for decades at a time.

And many regions have shown no significant net changes or trends in either direction relative to the last few hundred to thousands of years.

Succinctly, then, scientists publishing in peer-reviewed journals have increasingly affirmed that there is nothing historically unprecedented or remarkable about today’s climate when viewed in the context of long-term natural variability.

The following (partial) list has been organized by geographical region

Freeman Dyson, 94 today, on scepticism

by Paul Matthews, December 15, 2017


At the excellent Curious Wavefunction blog of Ash Jogalekar, there’s an article (posted last year) about Freeman Dyson, who is 94 today.

He disapproves of faith in computer models and of the zealous dogmatism exhibited by some climate change activists, and both these points are extremely well taken. Ultimately Dyson is saying something simple; that science progresses only when there is a critical mass of skeptics challenging the status quo

2017 in review: polar bear prophesies of doom more at odds with current reality

by Polar Bear Science, December 29, 2017


Tales of doom and gloom about polar bears reflect what some people think might happen in the future, not what is happening right now.  Currently, polar bears are doing just fine despite the low summer sea ice coverage they’ve experienced since 2007 (Crockford 2017a; York et al. 2016). In other words, there has been no global population decline as predicted: officially, the numbers were 22,000-31,000 (or 26,500 average) in 2015 (Wiig et al. 2015) but about 28,500 when estimates published since then are included (Aars et al. 2017; Dyck et al. 2017; Matishov et al. 2014; SWG 2016), up from about 22,500 in 2005).

NINE YEARS AGO… Al Gore Predicted North Pole Would Be Completely Ice Free by Today

by Jim Hoft, December 28, 2017 in GatewayPundit


NINE YEARS AGO THIS MONTH—
Al Gore predicted the North Polar Ice Cap would be completely ice free in five years.
Gore made the prediction to a German audience in 2008. He told them that “the entire North ‘polarized’ cap will disappear in 5 years.”

This wasn’t the only time Gore made his ice-free prediction. Gore’s been predicting this since 2007.

Where The Temperature Rules The Total Surface Absorption

by Willis Eschenbach, December 22, 2017 in WUWT


Reflecting upon my previous post, Where The Temperature Rules The Sun, I realized that while it was valid, it was just about temperature controlling downwelling solar energy via cloud variations. However, it didn’t cover total energy input to the surface. The total energy absorbed by the surface is the sum of the net solar energy (surface downwelling solar minus surface reflections) plus the downwelling longwave infrared, or DWIR. This is the total energy that is absorbed by and actually heats the surface.

CONTAMINATED ICE CORES: EVERYTHING WE KNOW ABOUT PALEO-CLIMATE MAY BE WRONG

by University of York, December 20, 2017 in GWPF

For the first time scientists have directly observed living bacteria in polar ice and snow — an environment once considered sterile. “As microbial activity and its influence on its local environment has never been taken into account when looking at ice-core gas samples it could provide a moderate source of error in climate history interpretations.”
