When Greenland was green in warmer times

Science: There’s something ancient in the icebox

Researchers find 3-million-year-old landscape beneath Greenland Ice Sheet

In this one-minute video, University of Vemont scientists demonstrate how they discovered 3 million-year-old soil under the Greenland Ice Sheet.

Glaciers are commonly thought to work like a belt sander. As they move over the land they scrape off everything—vegetation, soil, and even the top layer of bedrock. So scientists were greatly surprised to discover an ancient tundra landscape preserved under the Greenland Ice Sheet, below two miles of ice.

“We found organic soil that has been frozen to the bottom of the ice sheet for 2.7 million years,” said University of Vermont geologist Paul Bierman—providing strong evidence that the Greenland Ice Sheet has persisted much longer than previously known, enduring through many past periods of global warming.

Cook’s 97% climate consensus paper crumbles upon examination

pinocchio_puppetUgh. Do you remember the “97% consensus”, which even Obama tweeted?

Turns out the authors don’t want to reveal their data.

It has always been a dodgy paper (http://iopscience.iop.org/1748-9326/8/2/024024/article). Virtually everyone I know in the debate would automatically be included in the 97% (including me, but also many, much more skeptical).

The paper looks at 12,000 papers written in the last 25 years (see here, the paper doesn’t actually specify the numbers, http://notalotofpeopleknowthat.wordpress.com/2013/07/12/watch-the-pea/). It ditches about 8,000 papers because they don’t take a position.

About that overwhelming 97-98% number of scientists that say there is a climate consensus…

Larry Bell writes in his weekly Forbes column about that oft repeated but less than truthy “98% of all scientists” statistic. Supposedly, this was such an easy and quick to do survey, it was a no-brainer according to the two University of Illinois researchers who conducted it:

To maximize the response rate, the survey was designed to take less than 2 minutes to complete, and it was administered by a professional online survey site ( www.questionpro.com  ) that allowed one-time participation by those who received the invitation.

I think it is hilarious that so few people who cite this survey as “proof” of consensus actually look into the survey and the puny response numbers involved. So, I decided to graph the data to give some much needed perspective. Apparently, the majority of AGU members polled didn’t think this poll on climate change consensus was worth returning. – Anthony

No global warming for 17 years 8 months

RSS considers the cause of a Pause now half the satellite record long

By Christopher Monckton of Brenchley

Times are not easy for true-believers just now. The RSS satellite lower-troposphere temperature anomaly for March, just in, shows no global warming at all for 17 years 8 months. This remarkable 212-month period, enduring from August 1996 to March 2014, represents half of the entire 423-month satellite record since it began in January 1979.

clip_image002

Figure 1. The remarkable 212-month absence of global warming, notwithstanding a record rate of increase in CO2 concentration. The Pause – the least-squares trend on the data for the past 17 years 8 months – now extends to just over half the entire 423-month Remote Sensing Systems satellite record since January 1979.

Yet we should not crow. A strongish el Niño – we are rather overdue for one – may well shorten the Pause quite a bit, but…

Earth Hour 2012 – A dissent and poll

The winner for Earth Hour every year since 2003 - North Korea. Odds favor them to be the winner again this year.

Every year at Christmas, many newspapers reprint “Yes Virginia, there is a Santa Claus“, this excellent essay by Ross McKittrick should be repeated on every blog on every observance of Earth Hour. Copy, paste, and share it widely. A poll on what you plan to do to observe this event follows.

The whole mentality around Earth Hour demonizes electricity. I cannot do that, instead I celebrate it and all that it has provided for humanity. – Ross McKitrick

In 2009 I was asked by a journalist for my thoughts on the importance of Earth Hour.

Here is my response.

I abhor Earth Hour. Abundant, cheap electricity has been the greatest source of human liberation in the 20th century. Every material social advance in the 20th century depended on the proliferation of inexpensive and reliable electricity.

When Did Anthropogenic Global Warming Begin?

By WUWT Regular “Just The Facts”:

Note: This article builds upon a previous article, When Did Global Warming Begin?, which offers highly recommended background for this article.

There appears to be some confusion as to when humans might have begun to influence “Earth’s Temperature”. For example, “Global warming is the unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels.” NASA Earth Observatory “Ninety-seven percent of climate scientists agree that climate-warming trends over the past century are very likely due to human activities, and most of the leading scientific organizations worldwide have issued public statements endorsing this position.” NASA Climate Consensus page “‘Global warming started over 100 years ago‘: New temperature comparisons using ocean-going robots suggest climate change began much earlier than previously thought”. The Daily Mail “The temperature, they pointed…
