The British Isles were once neither British nor isles
Things aren’t always what they seem on the surface. Looking at the area between mainland Europe and the eastern coast of Great Britain, you probably wouldn’t guess it had been anything other than a great expanse of ocean water. But roughly 12,000 years ago, as the last major ice age was reaching its end, the area was very different. Instead of the North Sea, the area was a series of gently sloping hills, marshland, heavily wooded valleys, and swampy lagoons: Doggerland.

A new paper by renowned Swedish sea level expert Prof. Axel Mörmer published in the International Journal of Earth & Environmental Sciences dumps lots of cold water on the premise that today’s sea level rise is caused by man and is unusual.
Mörner’s paper looks back at the last 500 years of sea level rise and shows that natural variables are the major drivers, and not man-made CO2-driven global warming.

This is quite interesting. Remember the claim in on the front cover of Nature in 2009 by Steig and Mann that Antarctica was warming, thanks to that “special Mannian PCA math sauce” that was applied to air temperature data to smear surface temperature trends over the entire continent? It was dashed by climate skeptics who wrote a paper. It was accepted for publication and disproved (in my opinion) by a team of credible skeptics that wrote a counter-paper. But, there’s an interesting twist thanks to new and surprising data; Steig and Mann may have captured surface air temperature trends in the exact same areas that have been identified as geothermal hot spots.

While the effects of climate change on tree growth in forests have been extensively studied, there is little information available so far for urban trees”, said Professor Hans Pretzsch from the Chair for Forest Growth and Yield Science at TUM. The study supported by the Bavarian State Ministry for Environment and Consumer Protection as well as by the Audi Foundation for the Environment, which was published in the journal Scientific Reports, for the first time systematically examined the growth of urban trees worldwide for trends resulting from changing environmental conditions.

When continents break it gets warm on Earth
Rift zones released large amounts of CO2 from depth, which influenced global climate change.

(…)The body of evidence however clearly shows that the climate sensitivity is on the low side, about 1 to 1.5 degree increase per CO2 doubling. People in the climate community are scratching their heads trying to understand the so called hiatus in the warming. Where is the heat hiding? While in reality it simply points to a low sensitivity.

Of course, they had no choice but to withdraw the ludicrous claim about “ten times the global rate”!

(…) I am constantly amazed that the likes of Mark Lynas and Corrinne Le Quere are surprised to see emissions still rising.
If they had bothered to read the Paris Agreement and the INDCs, they would have known that was exactly what was intended.

Confirms what I’ve been saying all along!
NASA scientists admit that a massive heat source almost as hot as the Yellowstone supervolcano may be melting the Antarctic ice sheet from below.
It seems like a no-brainer to me. I mean, how can lakes and rivers be flowing beneath the ice unless there’s a heat source down there? And if sub-glacial volcanoes can be melting the ice, why couldn’t underwater volcanoes be heating the sea

With the Atlantic now devoid of tropical cyclones, I trust we can declare the season closed.
As we all know, its been one of the busier seasons in recent years. But it may surprise many to find that it has not been that unusual.

It is far too early to judge this year’s global temperature developments and their significance regarding the long-term warming trend.
The United Nations climate change conference, held in Bonn this year, is always the cue for press releases from the World Meteorological Office and the UK Met Office in which they give their assessment of the year based on 9-10 months of data.
Dealing with the El Nino of recent years (and don’t forget the ‘Pacific Blob’ before that) they have had difficulty with explaining what part of the record temperature was due to El Nino and natural, and what was anthropogenic.

An asteroid, also known as the Chicxulub Impactor, hit Earth some 66 million years ago, causing a crater 180 km wide. The impact of the asteroid heated organic matter in rocks and ejected it into the atmosphere, forming soot in the stratosphere.
According to the study, soot from hydrocarbon-rich areas caused global cooling of 8-11°C and cooling on land of 13-17°C. It also caused a decrease in precipitation by approximately 70-85 percent on land and a decrease of approximately 5-7°C in seawater temperature at a 50-m water depth, leading to mass extinction of life forms including dinosaurs and ammonites

The plots attached here are taken from the MOYHU blog maintained by Nick Stokes here. The software on the blog allows the global temperature anomaly data for each month for the last several years, it also allows the mesh showing the temperature measurement points to be turned on and off.

My first heresy says that all the fuss about global warming is grossly exaggerated. Here I am opposing the holy brotherhood of climate model experts and the crowd of deluded citizens who believe the numbers predicted by the computer models. Of course, they say, I have no degree in meteorology and I am therefore not qualified to speak.
But I have studied the climate models and I know what they can do.

In addition, we consider temperature dependent natural emission and absorption rates, by which the paleoclimatic CO2 variations and the actual CO2 growth rate can well be explained. The anthropogenic contribution to the actual CO2concentration is found to be 4.3%, its fraction to the CO2 increase over the Industrial Era is 15% and the average residence time 4 years.”
