The Little Ice Age And Medieval Warming In South Africa

by Paul Homewood, August 19, 2017

The climate industry likes to pretend that the Little Ice Age was just a local event in Europe, but studies like this one give the lie to that.

Interestingly this Tyson study also includes graphs of historical temperature trends in other parts of the world, for comparison. They all clearly show the MWP and Little Ice Age, although the peaks and troughs don’t always match.

NASA’s Secret Plan to Save Earth From Super-Volcanoes… Seriously?

by David Middleton, August 18, 2017 in WUWT

If “the supervolcano threat is substantially greater than the asteroid or comet threat,” does this mean we can stop fretting about Gorebal Warming and the Sixth Mass Extinction?  Is NASA really moving on to actual threats to the planet?  Well, not threats to the planet… The planet has handled supervolcanoes, asteroids and comets quite well over its 4.5 billion year lifespan.

Gilmer: We Should View The Permian Basin As A Permanent Resource

by David Blackmon, August 17, 2017 in Forbes

« We should view the Permian Basin as a permanent resource, » he says, « The Permian is best viewed as a near infinite resource – we will never produce the last drop of economic oil from the Basin. »

No one disputes that the resource in the Permian is huge, but ‘infinite’ is a big word.  I asked him to expand on that concept.

What do we know about Arctic sea ice trends?

by Dr. Ronan Connolly & Dr. Michael Connolly, August 16, 2017 in WUWT

Satellite observations indicate that the average Arctic sea ice extent has generally decreased since the start of the satellite records in October 1978. Is this period long enough to assess whether the current sea level trend is unusual, and to what extent the decline is caused by humans?

This change in Arctic climate is often promoted as evidence that humans are causing drastic climate change. For instance, an April 29th 2017 article in the Economist (“Skating on thin ice”, pg 16) implied that the Arctic is melting unusually, dramatically and worryingly (…)


The rise of algae in Cryogenian oceans and the emergence of animals

by Jochen J. Brocks et al., August 2017, in Nature

The ‘Rise of Algae’ created food webs with more efficient nutrient and energy transfers, driving ecosystems towards larger and increasingly complex organisms. This effect is recorded by the concomitant appearance of biomarkers for sponges and predatory rhizarians, and the subsequent radiation of eumetazoans in the Ediacaran period.

The Global Temperature Record Is A Farce

by Tony Heller, August 16, 2017 in DeplorableClimSciBlog

NASA says  97% of scientists agree that their temperature graphs are accurate, and NASA, NOAA, CRU and JMA all independently agree very precisely about global temperature going back to 1880.

This is quite remarkable, considering that NASA doesn’t agree with their own data, having doubled 1880-2000 warming over the past 15 years.
