One lonely molecule…

by Ian Plimmer, Geologist, June 17, 2017

If Australia emits 1.5 per cent of global annual CO2 emissions, 3 per cent of the total annual global emissions are anthropogenic and the atmosphere contains 400 parts per million by volume of CO2, then one molecule in 6.6 million molecules in the atmosphere is CO2 emitted from humans in Australia. This molecule has an atmospheric life of about 7 years before it is removed from the atmosphere by natural sequestration into life and limey sediments.

It’s Said That ‘97% of Climate Scientists Agree’ About Global Warming – But Do They?

by Neil Frank, June 9, 2017

A variety of studies have purported to find an overwhelming consensus among climate scientists on global warming. However, the studies rarely specify what it is to which the scientists agree

Neil L. Frank, Ph.D. (Meteorology), was the longest-serving Director of the National Hurricane Center (1974–1987) and is retired Chief Meteorologist of KHOU-TV, Houston (1987–2008). Living in Fulshear, TX, he continues research on global climate change while serving as a Fellow of The Cornwall Alliance for the Stewardship of Creation.

Hundreds Of Scientific Papers Challenge ‘Global’ Warming

By Kenneth Richard, June 16, 2017 in NoTricksZone

Recently, an article citing over 80 graphs from scientific papers published in 2017 — and another 55 graphs from 2016  — established that modern “global” warming is not actually global in scale, and that today’s warmth is neither unprecedented or remarkable when considering the larger context of natural variability.

Here, an additional 140 non-hockey stick graphs taken from papers published in 2015 and earlier have now been made available.  With this latest installment, graphical temperature reconstructions challenging the conceptualization of global-scale or unprecedented modern warming are rapidly approaching 300.


The Vostok Ice Core: Temperature, CO2 and CH4

by Euan Means, December 12, 2014

In their seminal paper on the Vostok Ice Core, Petit et al (1999) [1] note that CO2 lags temperature during the onset of glaciations by several thousand years but offer no explanation. They also observe that CH4 and CO2 are not perfectly aligned with each other but offer no explanation. The significance of these observations are therefore ignored. At the onset of glaciations temperature drops to glacial values before CO2 begins to fall suggesting that CO2 has little influence on temperature modulation at these times.

Global versus Greenland Holocene Temperatures

by Andy May, June 19, 2017 i

Last week, I posted a global temperature reconstruction based mostly on Marcott, et al. 2013 proxies. The post can be found here. In the comments on the Wattsupwiththat post there was considerable discussion about the difference between my Northern Hemisphere mid-latitude (30°N to 60°N) and the GISP2 Richard Alley central Greenland temperature reconstruction (see here for the reference and data). See the comments by Dr. Don Easterbrook and Joachim Seifert (weltklima) here and here, as well as their earlier comments.
