New evidence from clams and mussels with temperature-sensitive habitat requirements confirm that warmer temperatures and less sea ice than today existed during the early Holocene period about 10.2–9.2 thousand years ago and between 8.2 and 6.0 thousand years ago (based on radio carbon dates) around Svalbard. Barents Sea polar bears almost certainly survived those previous low-ice periods, as they are doing today, by staying close to the Franz Josef Land Archipelago in the eastern half of the region where sea ice is more persistent (…)

Could someone explain in 100 words or less without complex algebraic formulas how the trace gases, approximately 1% of the atmosphere can overtly control the temperatures of the remaining 99% atmospheric constituents?

SPOTLIGHT: After the Intergovernmental Panel on Climate Change (IPCC) report was released in 2007, its dramatic findings of species extinction were repeatedly emphasized by chairman Rajendra Pachauri.
BIG PICTURE: When it examined the question of species extinction, the 2007 IPCC report relied heavily on a single piece of research – a Nature cover storypublished early in 2004. Written by Chris Thomas and 18 others, this was the source of Pachauri’s claim that climate change threatened 20 to 30% of the world’s species.

Sky News, one of Australia’s most popular news services, just gave climate skeptic and geologist Ian Plimer an honest opportunity to explain what is wrong with Australia’s climate obsessed energy policies.
Geologist Ian Plimer told The Outsiders that Energy Minister Josh Frydenberg had caught himself ‘between a rock and a hard place’ when it comes to the government’s energy policies. Mr Plimer said it wasn’t possible for the energy market to provide cheap and reliable energy, but also reduce emissions.

Agriculture could pull carbon out of the air and into the soil — but it would mean a whole new way of thinking about how to tend the land.

You think we had a bad winter here in the USA? Look at Japan where they have walls of snow 56 feet tall (almost the height of a 6-story building).
There’s an avalanche of tourists coming to the Tateyama to see the walls of snow.
It has been a rough winter full of snow all over the northern hemisphere, as this newest NOAA-20 satellite image shows

Coral reefs are facing no shortage of threats including ocean acidification, overfishing, plastic pollution, and rising temperatures. Sea surface temperatures have been climbing on average for over a century, and ocean heat waves—which can trigger coral bleaching events—are becoming more common and severe. Scientists have long worried that as coral-killing spikes in temperature become more frequent, corals won’t have enough time to recover between bleaching events and will ultimately go extinct. But a new paper, published today in PLoS Genetics, suggests that corals might be able to adapt to another century of warming.

Oil saw significant gains in anticipation of the strikes in Syria, but following U.S. efforts to ease geopolitical tensions in the region, crude prices have stabilized.

Michael Kruger at German skeptic site Science Skeptical here writes about how solar energy indutry in Germany has disintegrated spectacularly.
What follows are 4 charts that show us some shocking trends, and how in reality the German solar industry has seen a bloodbath that can be rated as one of the worst in a long time. The reality is that Germany’s green revolution is far from being a model for the world.

In the May 2000 issue of Reason Magazine, award-winning science correspondent Ronald Bailey wrote an excellent article titled “Earth Day, Then and Now” to provide some historical perspective on the 30th anniversary of Earth Day. In that article, Bailey noted that around the time of the first Earth Day in 1970, and in the years following, there was a “torrent of apocalyptic predictions” and many of those predictions were featured in his Reason article. Well, it’s now the 48th anniversary of Earth Day, and a good time to ask the question again that Bailey asked 18 years ago: How accurate were the predictions made around the time of the first Earth Day in 1970? The answer: “The prophets of doom were not simply wrong, but spectacularly wrong,” according to Bailey.
Here are 18 examples of the spectacularly wrong predictions made around 1970 when the “green holy day” (aka Earth Day) started

The famous Oxford Dodo died after being shot in the back of the head, according to new research. Using revolutionary forensic scanning technology and world-class expertise, researchers have discovered surprising evidence that the Oxford Dodo was shot in the neck and back of the head with a shotgun.
The significant and unexpected findings, made by Professor Paul Smith, director of the Museum of Natural History, and Professor Mark Williams from WMG at the University of Warwick, only became apparent when mysterious particles were found in the specimen during scans carried out to help analyse its anatomy.

The Arctic region was the largest contributor to the positive slope in global temperatures in recent decades.
Consequently, the anomalously rapid warming in the Arctic region (that occurred prior to 2005) has been weighted more heavily in recent adjustments to instrumental temperature data (Cowtan and Way, 2013; Karl et al., 2015) so as to erase the 1998-2015 hiatus and instead produce a warming trend.
Meanwhile, other scientists have been busy determining that only about 50% of the warming and sea ice losses for the Arctic region are anthropogenic, or connected to the rise in CO2 concentrations.
The rest of the warming and ice declines can be attributed to unforced natural variability.

The first half of April was third coldest in the past 110 years in the US, and the coldest since 1975. The three warmest first fifteen days of April occurred in 1910, 1930 and 1925, when about 80% of days were over 60 degrees.

I’ve been regularly bringing you climate and energy news from Germany, with Kenneth in USA posting on the latest science.
Now NoTricksZone is happy to report we are also working with skeptic Japanese climate blogger Kirye, who runs KiryeNet. This means we’ll also be occasionally presenting skeptic news out of Japan in English.
For example in last Tuesday’s post Kirye delivered the key parts on the Arctic Freezamageddon. Our aim is to provide more of such posts in the future.
Views from other countries like Japan are always extremely useful. There really isn’t any global climate science consensus. It’s fraudulent to claim that there is.

In early 2017 scientists announced the discovery of possible desiccation cracks in Gale Crater, which was filled by lakes 3.5 billion years ago. Now, a new study has confirmed that these features are indeed desiccation cracks, and reveals fresh details about Mars’ ancient climate.
“We are now confident that these are mudcracks,” explains lead author Nathaniel Stein, a geologist at the California Institute of Technology in Pasadena. Since desiccation mudcracks form only where wet sediment is exposed to air, their position closer to the center of the ancient lake bed rather than the edge also suggests that lake levels rose and fell dramatically over time.
