Looks like you’re probably wrong on that unsupported assertion, CosmicTitan.

Here’s how The Guardian reported GISS’ Schmidt on Aug. 30, 2016.

“The planet is warming at a pace not experienced within the past 1,000 years, at least, making it “very unlikely” that the world will stay within a crucial temperature limit agreed by nations just last year, according to Nasa’s top climate scientist.

“This year has already seen scorching heat around the world, with the average global temperature peaking at 1.38C above levels experienced in the 19th century, perilously close to the 1.5C limit agreed in the landmark Paris climate accord. July was the warmest month since modern record keeping began in 1880, with each month since October 2015 setting a new high mark for heat.

“But Nasa said that records of temperature that go back far further, taken via analysis of ice cores and sediments, suggest that the warming of recent decades is out of step with any period over the past millennium.

“In the last 30 years we’ve really moved into exceptional territory,” Gavin Schmidt, director of Nasa’s Goddard Institute for Space Studies, said. “It’s unprecedented in 1,000 years. There’s no period that has the trend seen in the 20th century in terms of the inclination (of temperatures).”

“Maintaining temperatures below the 1.5C guardrail requires significant and very rapid cuts in carbon dioxide emissions or co-ordinated geo-engineering. That is very unlikely. We are not even yet making emissions cuts commensurate with keeping warming below 2C.”

“Temperature reconstructions by Nasa, using work from its sister agency the National Oceanic and Atmospheric Administration, found that the global temperature typically rose by between 4-7C over a period of 5,000 years as the world moved out of ice ages. The temperature rise clocked up over the past century is around 10 times faster than this previous rate of warming.

“The increasing pace of warming means that the world will heat up at a rate “at least” 20 times faster than the historical average over the coming 100 years, according to Nasa. The comparison of recent temperatures to the paleoclimate isn’t exact, as it matches modern record-keeping to proxies taken from ancient layers of glacier ice, ocean sediments and rock.”

In choosing not to see the elephant in the room CosmicTitan, you’ve also decided that your chosen political alignment is more important than the facts of the matter. That’s fine but it has nothing to do with the science of global warming and climate change, which remains intact whether you believe it or not.

The Guardian. Now there is an objective scientific journal on note. No political bias whatsoever. The discussion was on glacial retreat and how that began long before the wide scale burning of fossil fuels before you launched into your diatribe replete with red herrings and arguments to authority. Only the East Anglia university's finest have done away with the Maunder Minimum and the Millenium Warm Period. Hockey mates of yours, I presume?

On a more scientific note you may with to peruse the paper by Robinson et. al, 2007 who track and composite the retreat of 169 glaciers from 1700 to 2000. There is no evidence that the rate of retreat has accelerated with the burning of fossil fuels and plenty of evidence that the retreat began long before the burning of fossil fuels.

The only pachyderm in the room is those sucking lively and lustily from the teat of taxpayer largess and whose desperation to prolong the scam is palpable.
